Summary: Polishing is any moulds produce one of the process important segment. Electrochemistry of the electrochemistry polish with article more advanced introduction, groovy mechanical polish, union plays mark function. Keyword: Polishing technology; Model antrum mould; Exterior quality; Electrolyte organizes preface as rubber-plastic rapid development of industry, people is right rubber-plastic the exterior quality demand of goods is higher and higher, often ask the surface of the mould reachs the level of lens face. If inject,surface roughness of model antrum surface is worth a requirement to achieve Ra0.

1-0.

The level of 25 μ M. The method of polishing is more. Have manual polish, chemical polish, electroanalysis polishing, supersonic polish, extruding honing polish, machinery rotates, move back and forth or shake polishing to wait. But more complex to appearance model for antrum mould, still can use equipment and the method that close suitably by hand to solve only. 1 electrochemistry introduces a kind here beforehand relatively advanced and the electrochemistry polish that people has not known deep. The metal that the surface such as the metallic spare parts that electrochemistry polish is pair of complex form, mould undertakes deliquescent purify measures electrochemistry positive pole certainly expresses facing, repair in order to achieve grind or polishing purpose new technology of a kind of compound treatment. Report builds the limitation that grinds polishing not to suffer metallic stuff hardness and tenacity to wait. Wait to all can undertake repairing grinding polishing to material of all sorts of hard steel of temper by dipping in water, alloy steel, stainless steel and heat-resisting alloy, hard alloy. In recent years, report is repaired grind polishing technology to already applied at mould of each type antrum. Especially model of Die Casting of plastic injection mould, metal, forging die, hard alloy plays late pattern and different part. For example of blade model polish of face, Xie Gen, the exterior metamorphism that uses the presence after purify electric spark is machined is sclerotic layer, each abnormity aperture and abnormity go burr and pour a variety of sides such as the circle, already obtained favorable treatment result now. 1.

1 electrochemistry repairs the principle electrochemistry that grinds polishing the principle that grinds polishing and electroanalysis grinding is similar, deliquescent action gives priority to its electrochemistry positive pole with the metal, slight mechanical scrape action is complementary, accompany have faint scintilla discharge effect. The electrochemistry positive pole of alleged metal is deliquescent action, common ground is told can compare eletroplating contrary process. Will be repaired grind namely or the workpiece surface of polishing dissolves directionally one, the dimension of this one deliquescent process is OK pilot. Electrochemistry positive pole is deliquescent in the process, metallic surface generates a large number of electroanalysising child (if oxidize,film and hydroxide garrulous install the) such as content, enclothe in workpiece surface, affect further electrochemistry reaction. This is explicit the ionic chroma that stands by workpiece electrode surface to handle solution and the ionic consistency with internal solution have apparent difference, make farther electrochemistry positive pole deliquescent generation is difficult, exterior quality worsens badly. So report is repaired the tool that the graph shows 1 times is used to serve as cathode when grinding polishing, tool electrode surface contains abrasive. The tool when be being operated so and workpiece also do not send generation short circuit when slight contact is mobile. Graph when 1 pair of workpiece undertake polishing, the positive pole of will special direct current source receives work, electric tool receives the cathode of power source. Pour out of right amount and fresh electrolyte from electric tool wheelhead. When electric conduction grinds an as slight as workpiece contact to make opposite motion, the metal of workpiece surface produces electrochemistry positive pole to dissolve, electroanalysis the abrasive that child and loose zincous film are ground to provide by electric conduction ceaselessly (diamond film) scrape, electroanalysis child and electroanalysis the quantity of heat that reaction produces is flowed to take away by electrolyte. As electroanalysis of reaction undertake ceaselessly, the prominent place of metallic surface, be dissolved by electrochemistry above all, achieve thereby whole the smooth, dimension that till obtain,asks and surface roughness. Any moulds that this kind of equipment comes out to looking front cut, electric spark is machined undertake beforehand polishing is very advantageous. Graph and model antrum polish can use electric black lead and file of abnormity electric conduction to undertake polishing (see a picture 2, graph 3) . 1.

The characteristic of 2 electrochemistry polish (1) electric mould does not want as mechanical as handiwork rasp to exert oneself to do sth. in that way when as slight as workpiece contact, operation only, so report is repaired grinding polishing is a kind of very slight labor, can reduce the polishing labor intensity that the mould is versed in. (When 2) electric tool is used, contact gently with workpiece only, wear away little, service life is long; File of diamond electric conduction wants only not by scintilla burn or receive turn over power source, basically do not have loss. Oilstone of electric black lead has small loss. (The degenerative and sclerotic layer that 3) report builds the surface after grinding polishing electric spark to machine to exist, those who cast part of smooth complex form model face. Especially ministry of the horn of the mould, root, groove, narrow seam etc particularly effective. Can save the 70 % left and right sides at manual polish time. (4) report is repaired grind polishing the data with all sorts of hard temper by dipping in water, do not accept hardness restriction. That is to say polishing the rolled steel such as the CrR with all sorts of hard temper by dipping in water, T8, 5CrMnMo, Cr-WMn even hard alloy also can resemble polishing common mild steel is euqally easy. (5) classics report repairs surface of the metal after grinding polishing not to have any nick, can use sand paper of 1000 eye metallographic or oilstone directly farther polish. (6) report is repaired grind polishing nonexistent cutting force. Polishing hind won't make generation of thin wall workpiece is out of shape, won't produce burr and heat to be out of shape the layer. Classics report repairs the workpiece face that wears polishing is metallic stuff " true " the surface. (7) electrochemistry polish has pledged like material, the operation skill that adds adroitness and rich polishing experience can be cast to surface roughness RaO commonly.

1 μ M is controlled. Polish of 2 mechanical essence wants to make the mould achieves the demand with lens higher even area, still must cooperate machinery to undertake essence of life is cast. Commonly used machinery is the table with adjustable rotate speed or polisher of flexible shaft of condole type emery wheel. It is OK needle of the proper emery wheel on clip, felt annulus, hardwood annulus, colophony annulus, bamboo undertake essence of life is cast. Want to achieve lens face or satisfactory result. The process of polishing should note two respects: (Each measure of 1) polish must keep clean; (2) notes the alternative of polishing tool, order. Specific as follows: What ① polish must not have dirt in cleanness is indoor undertake. Hard grit can pollute abrade material, damage already was close to finished mould appearance. Every polish that polishing tool uses a level only gets ② gesso, be sure to keep in mind to cannot be mixed with. When ending to polishing especially, meet otherwise all one's previous efforts wasted. ③ should want changeover finer when the arenaceous date of one class, must clean both hands and workpiece. Clean both hands with soap, with the dissolvent that divide fat (clean kerosene, special clear lotion) clean workpiece. ④ hand is moved (artificial) when polishing, get gesso to want besmear to be on polishing tool; When mechanical polish abrade cream want besmear to be on workpiece. The hardness of the pressure that uses when ⑤ polish and polishing tool and abrade the grade that cream should be adjusted each other and suit. Undertake the finest when the polish of one class, pressure should adjust the weight with polishing tool to comparative. When use oilstone polish, because oilstone does not have flexibility, complete the feeling by the hand. If pressure is too great, not only cannot knife mark purify, stay instead deeper closer oilstone mark. ⑥ should achieve rate of older rolled steel purify, the diamond that must use stronger polishing tool and thicker arenaceous bead creams. The final polish of ⑦ plastic mould should undertake along the direction of work drawing of patterns. ⑧ begins polishing is to want to handle corner, side first horn, round horn and narrow seam the place that waits to be cast harder. ⑨ handles kind of horn and edge horn to answer special caution, the attention does not form round part or collapse edge, answer to use stronger polishing tool as far as possible. If ⑩ needs to use when brush cloth or brushing paper to undertake wiping brushing smear phenomenon, must every measure brush the cloth, departure that brush paper to use, do not mix brush with chaos, lest better workpiece face cut. 3 etch hit mark to use electrochemistry positive pole likewise deliquescent principle, can undertake printing label, design, character to wait in any slick metal surfaces. Be like all sorts of steel of steel of stainless steel, carbon, all sorts of alloy steel, tool, hard alloy, aluminium alloy, plating surface of metal of all sorts of material of line of chromic, plating, galvanization, grinding, polish. Can use at printing name of name of mark badge, product, technical index, firm, safety accident and make sign of high-grade stainless steel, crust hit mark to wait. 3.

1 application method controls the content that should print on velar edition (edition of large quantities of silk screen of system of quantities, small lot is printed go up in stencil film edition. Use common typewriter to be able to print the) that make. Be operated for advantage and secure, desirable harder and the transparent nylon flimsy of level off, delimit among dig a more largish than content square hole, follow cement of velar edition brim to secure with paper of transparent thin adhesive plaster next but. Use a velar edition to be put on the workpiece that should print (graph 4 express) . workpiece of catching of power source anode, negative pole catching makes sign work head. Head of the job that make bid can use black lead or metal, carry the calico on biscuit, facilitate touch take electrolyte. General tone is voltage 10-18V is advisable. The electrode job head that has the package cloth dips in take electrolyte to be pressed gently in velar edition above, electrolyte permeates the label of velar edition or character to wait namely, enter workpiece surface to undertake positive pole dissolves, 2-3 second can. Removed electrode, stencil. An elegant label is printed namely came out, never fall off. Graph 4 dozens of indicative intents 3.

Tool of hardware of ① of 2 application limits, knife, cut, tool of hard alloy of cutting tool of clamp, measure. Product of crust of goods of ② stainless steel, stainless steel. Cabinet of cup, crock, crock, eat is provided, food tool. Parts of an apparatus of ③ appearance component, electronic parts, medical treatment, horological glasses. A replacement of spare parts of bearing of accessory of ④ machine tool, gear, valve, machine, car. 3.

3 have distinctive and clinking advantage ① accomplishment of its label, word is normal, clear, fast, changeless color, do not fall off, high temperature resistant, do not be afraid that organic dissolvent is swabbed. ② no matter product volume, planar, dambered surface, chip can be printed, print careful. M of deepness 5-100 μ . ③ operation is handy, need a few seconds to be able to be finished only, need not stoving solidify. ④ can make several kinds of facial expression. General metal but black and white. If the convention such as iron, stainless steel, copper can hit a black. The convention such as aluminous, chromic, line can call a white. Via experiment basis the property of material differs, deserve to be able to be hit than differring with the component of electrolyte a color and mixture color. This is any engraving that those who make a tool cannot be likened to. Because 4 conclusion are current market competition is intense, the product changes fast, quality asks to also rise ceaselessly, the precision to the mould and polishing demand are consequently higher and higher also. To achieve the surface roughness that reduces mould surface, shorten mould treatment cycle and the goal that reduce finished cost. People already changed a lot of treatment way. The equipment of advanced high-tech also appears ceaselessly. But will tell to mould polish, remain a difficult problem that studies on international, because of mould appearance complex characteristic decides this, return rate of tall without degree of a kind of automation, polish fast, precision a kind of equipment of satisfaction of good, surface roughness, because this is current,still give priority to with manual polish. Electrochemistry is cast beforehand, mechanical essence is cast, etch the three-in-one that make bid body polish equipment, at present home already had manufacturer production. For national patent product, already small lot puts in the market, be agreed reputably. Write the ceaseless promotion application that grinds polishing technology as electrochemistry machinery, regular meeting is created and accumulate the experience with more valuable more, provide more extensive application example, serve for numerous mould polish connoisseur.
