A kind of processing method of glass mold mouth mould
Technical field
The invention belongs to the glass mold processing technique field, be specifically related to a kind of processing method of glass mold mouth mould.
Background technology
Such as industry knowledge, the vial oral area is nearest with bottle content shape thing, its quality good or not directly influences the quality of content, and is therefore very strict to the requirement of vial oral area moulding.
Mouthful mould is the vitals of restriction vial oral area portion moulding in the glass mold assembly, is made up of two half modules opposite each other, and its inner chamber cooperates with choma, sleeve, drift etc., and the outside matches with blank mould again.Therefore in all parts of glass mold, at most, precision is the highest for the mating surface of mouthful mould (the joint close face when mating surface is meant two half module matched moulds, down together), and structure is the most complicated.Because in use simultaneously, mouthful mould wearing and tearing are big, heat is concentrated, and the material that causes ideal making mouth mould is the composite that high rigidity material (like copper alloy) adds the inner chamber surfacing.Therefore, in the glass mold all component, the hardness of mouthful mould also is the highest, and processing is got up just very difficult naturally.If mouthful mould precision is not up to standard, it is poorly sealed directly to cause glassware to be mixed behind the lid, adverse consequences such as cause gas leakage easily, leak.If cause occurring the glass overlap owing to mouthful mould precision is defective, also can consumer's physical and mental health even life security be caused a hidden trouble.
Exactly because a mouthful mould has the above-mentioned notable feature that is different from other moulds in the glass mold, the processing method that causes the processing of mouthful mould can not directly apply mechanically other moulds (like Cheng Mo, blank mould etc.) in the glass mold.Traditional mouth mould processing method is generally: at first, with the two ends of clamp clamps mouth mould, joint close faces up, and planer digs the joint close face and cooperates muscle; Then, carry out manual repair, guarantee quality of fit; Then, two mouth moulds are cooperated, four-jaw chuck clamp blank cylindrical one end is calibrated bad mold joint, turning with scriber; Follow flange car other end cylindrical again; At last, process other positions, obtain a mouthful mould finished product.
The shortcoming of this traditional mouth mould processing technology is: at first, when planer processing joint close face, need the cost long time to calibrate, machining accuracy is low again simultaneously, requires very high to workman's operation technical ability; Secondly, manual repair need spend the longer time, when carrying out scriber calibration bad mold joint, beats repeatedly with hammer and to smooth, and same precision is low, and efficient is slow, and product quality is low-grade.The mouth mould that processes like this is rough surface often, and interchangeability is poor, unique the matching of die that a secondary punch can only match with it, can't use in case just obscure.Therefore, tradition mouthful mould processing method often is difficult to guarantee the precision of mouthful mould, and length, inefficiency, scrappage remain high the production cycle.
