Clamping mechanism for machining glass die

Abstract

The invention discloses a clamping mechanism for machining a glass die and belongs to the field of frock clamps. The clamping mechanism comprises a base, a support module fixing seat and a support module, wherein a pressure foot sliding chute is formed in a flat surface; a pressure foot is arranged in the pressure foot sliding chute; a support module fixing seat sliding cavity is formed in the base; the support module fixing seat is matched with a support module sliding cavity; a support module fixing seat nut is matched and arranged on the support module fixing seat; one end of a support module fixing seat lifting screw is connected onto the support module fixing seat nut; the other end of the support module fixing seat lifting screw is supported on the flat surface; the support module is fixedly connected with one side of the support module fixing seat; one end of the pressure foot extends out of the surface of one side of the base; a first guide sliding chute and a second guide sliding chute are formed in one side of the base; and a bottle die end surface positioning mechanism is matched and arranged on the other side of the base. The clamping mechanism has the advantages that the carving machining for an inner cavity of the glass die is realized without adopting a traditional an electric spark mode; the carving quality and efficiency are ensured; the clamping mechanism is convenient and quick in operation and is favorable in clamping adaptability; resources are saved and the interference influence on the die cavity is avoided.

Description

technical field [0001] The invention belongs to the technical field of fixtures, and in particular relates to a fixture mechanism for glass mold processing. 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 centers...

Problems solved by technology

However, due to the lack of suitable glass molds in the prior art, they can be put into machining centers, high-degree-of-freedom CNC multi-axis machine tools (usually four-axis) or equipped with known tiltable CNC rotary machines. Ordinary machine tools on the workbench carry out engraved fixture mechanisms, so EDM is commonly used, but EDM has the following technical problems: first, the processing cost is high, and the processing efficiency is low, so it is difficult to meet the requirements of industrialized enlarged production; second, The quality is difficult to guarantee, the depth of pattern texture is difficult to control and even easy to damage the glass mold, because although the pattern depth of pattern processing is superficial, it objectively produces different degrees of splitting effect on the inner cavity of the glass mold, so if the depth of pattern texture Improper control and significantly exceeding the depth required by the process will leave a risk of cracking in the service process of the glass mold; third, it will affect the smoothness of the surface polishing in the subsequent process, because there are many microscopic surfaces on the pattern surface after EDM. The concave and convex surfaces, these concave and convex surfaces are difficult to achieve the desired finish by polishing, thus affecting the overall smoothness of the mold cavity, and finally affecting the transparency of the glass container, so that the grade of the glass container cannot be improved

[0003]In addition, due to the different uses of glass containers, there are differences in specifications, such as the length (also called height) of glass cans relative to wine bottles and beer bottles Therefore, the size of the glass mold used to make glass cans is different from that used to make red wine bottles and beer bottles. Therefore, the tooling fixture must meet the requirements of both the length and length of the glass mold. Only in this way can it work To achieve good adaptability, otherwise it is necessary to deal with two kinds of long and short fixtures separately, resulting in waste of resources and inconvenience to management

Also, because a set of glass molds is composed of a pair of half molds with the same structure, and because the process requirements for mold cavity carving are more stringent than for joint processing, and because the mold cavity (also called Inner cavity or mold cavity) has a semicircular tendency or an irregular curved surface, so it is critical to the structure of the fixture mechanism, for example, the fixture mechanism is not allowed to have any interference effect on the mold cavity

[0004] may be due to factors that are not limited to the above examples, so in the Chinese and foreign patent documents and non-patent documents disclosed so far, it has not been used for the mold cavity The technical enlightenment of the clamp mechanism for clamping the glass mold during engraving processing, and there is no relevant report on the successful use of it in the industry
