Work fixture for glass mould machining

Abstract

The invention discloses a work fixture for glass mould machining, belonging to the technical field of the work fixture. The work fixture comprises a base, a support mould block fixed seat and a support mould block, wherein the surface of one side of the base is provided with a pressure pin sliding chute; a pressure pin is arranged on the pressure pin sliding chute in a matching manner; the base is provided with a support mould block fixed seat sliding cavity; the support mould block fixed seat is matched with the support mould block sliding cavity and provided with a support mould block fixed seat nut in a matching manner; the support mould block fixed seat nut is connected with one end of a support mould block fixed seat lifting screw rod; the other end of the support mould block fixed seat lifting screw rod is supported on the pressure pin sliding chute; the support mould block is fixed with one side of the support mould block fixed seat; one end of the pressure pin stretches out of the surface of one side of the base; one side of the base is provided with a first guide sliding chute and a second guide sliding chute; and the other side of the base is provided with a bottle mould end face locating mechanism in a matching manner. The work fixture for glass mould machining disclosed by the invention has the advantages that the conventional electric sparking method for carving the inner cavity of a glass mould is gotten rid of, the carving quality and efficiency are ensured, the operation is convenient and rapid, the work fixture has good clamping adaptability, and resources are saved.

Description

technical field [0001] The invention belongs to the technical field of tooling fixtures, and in particular relates to a tooling fixture for processing glass moulds. Background technique [0002] Fixtures play a very important role in the production of industrial products, and the processing of glass molds is no exception. The so-called tooling fixture refers to special equipment or tools used to clamp or position workpieces in machining to meet certain process requirements. Fixtures usually need to meet the requirements of no interference during product production, accurate and reliable positioning, and convenient operation. Since the tooling fixture has the exclusive characteristics of manufacturing a certain product, the degree of generalization is low, and it is often made by the manufacturer of mechanical products. Glass mold manufacturers also mostly equip various tooling fixtures in a self-made way. In recent years, although all kinds of medium and high-end machining...

Problems solved by technology

However, due to the lack of suitable fixtures in the prior art that allow the glass mold to be put into a machining center for engraving in an ideal clamping state, electric discharge machining is generally used, but there are the following technical problems in electric discharge machining: one, The processing cost is high, and the processing efficiency is low, so it is difficult to meet the requirements of industrial scale-up production; second, the quality is difficult to guarantee, the depth of the pattern texture is difficult to control, and even the glass mold is easy to be damaged, because the pattern processing, that is, the depth of the carved pattern is superficial, but objective Therefore, if the depth of the pattern texture is improperly controlled and significantly exceeds the depth required by the process, it will leave the glass mold with the risk of cracking during the service process; third, after the impact The smoothness of the surface polishing in the first process, because there are many microscopic concave-convex surfaces on the surface of the pattern after EDM, it is difficult for these concave-convex surfaces to achieve the desired smoothness through polishing, thus affecting the overall smoothness of the mold cavity, and finally affecting the transparency of the glass container. The grade of the glass container cannot be upgraded

In addition, because glass containers vary in specifications depending on their uses, for example, the length (also known as height) of glass cans is significantly shorter than that of wine bottles and beer bottles, so the glass used to make glass cans The size of the mold is different from the size used to make red wine bottles and beer bottles, so the fixture must meet the requirements of both the length and length of the glass mold. Only in this way can it play a good role in adaptability. Two kinds of tooling and fixtures, resulting in waste of resources and inconvenience to management

[0004] For the above prior art, the applicant has searched the literature, but there is no corresponding technical inspiration in the published Chinese and foreign patents and non-patent literature
