Clamp for processing glass mould

Abstract

The invention discloses a clamp for processing a glass mould, and belongs to the technical field of tooling clamps. The clamp comprises a base, a first clamp platform fixed mount, a second clamp platform fixed mount, a first mould horizontal adjusting mechanism, a second horizontal adjusting mechanism and a clamp platform driving mechanism, wherein a pair of guide rail bars is arranged on two sides of the base respectively, a clamp platform fixed mount sliding seat is arranged between the guide rail bars, and guide rails and a clamp platform moving chamber are formed on the clamp platform fixed mount sliding seat; the first clamp platform fixed mount and the second clamp platform fixed mount are positioned on the base respectively, a first acting cylinder and a second acting cylinder are fixed at two ends of the first clamp platform fixed mount and the second clamp platform fixed mount respectively, and a first clamp platform fixed seat and a second clamp platform fixed seat are fixedin the middle parts of the first clamp platform fixed mount and the second clamp platform fixed mount respectively; the first mould horizontal adjusting mechanism and the second mould horizontal adjusting mechanism are arranged on the first clamp platform fixed mount and the second clamp platform fixed mount respectively; and the clamp platform driving mechanism is arranged on the base. The clampis characterized by also comprising a pair of horizontal supporting adjusting mechanisms which are arranged on a pair of guide rail bars respectively, wherein each horizontal supporting adjusting mechanism comprises an adjusting base, an adjusting top plate and a group of elastic stretching devices. The clamp has the advantage that a half-mould of the glass mould cannot fall off to ensure the processing quality.

Description

technical field [0001] The invention belongs to the technical field of fixtures, and in particular relates to a fixture for glass mold processing. Background technique [0002] Fixtures play a very important role in the production of industrial products, and the production of glass molds is no exception. The so-called tooling mold 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 (comprehensi...

Problems solved by technology

[0006] However, the above-mentioned structure still has shortcomings in the actual use process, due to the longitudinal direction of the glass mold half mold held between the first and second clamps The middle and lower parts are in a suspended state, that is to say, the middle and lower parts of the outer circular surfaces on both sides of the length direction of the glass mold half-mold lack the necessary support, so the first and second mold level adjustment mechanisms act on a pair of joints at the same time. surface, it is very likely that it is difficult to obtain the overall levelness of the glass mold half-mold, especially when the first and second mold level adjustment mechanisms leave the joint surface, and in the process of machining the joint surface or mold cavity by the CNC machine tool In the process, the horizontality of the glass mold half changes, and even the sinking phenomenon occurs. The so-called sinking phenomenon refers to the glass mold half breaking away from the first and second clamps and falling
