Core pulling structure for stripping composite sliding blocks from front mold and rear mold

Abstract

The invention discloses a core pulling structure for stripping composite sliding blocks from a front mold and a rear mold. The structure is characterized by comprising a conventional sliding block and an oil cylinder driving sliding block, wherein the conventional sliding block and the oil cylinder driving sliding block are arranged on the two sides of a plastic product; the conventional sliding block is fixedly connected to one end of a rear mold core-pulling drawing block; a rear mold core-pulling sliding block is arranged on the rear mold core-pulling drawing block; the rear mold core-pulling drawing block makes contact with a stopping block in a collision mode when the rear mold core-pulling pulling block is in a mold closing state; the oil cylinder driving sliding block is fixedly connected to the front mold core pulling sliding block through the front mold core-pulling drawing block and is connected to an oil cylinder; and angle pins are arranged on the conventional sliding block and the front mold core-pulling drawing block separately. The core pulling structure for stripping the composite sliding blocks from the front mold and the rear mold has the advantages that a structure of a rear mold supporting plate can be omitted, a structure of a front mold supporting plate can be omitted, the thickness of a mold can be decreased, and the cost can be reduced; parting only needs to be performed at a time so as to realize the mold stripping of the product, the working steps can be reduced, the mold opening operation can be simple, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to a core-pulling structure for a front and rear mold of a composite slider, which belongs to the field of molds for plastic products. Background technique [0002] With the increasing development of the plastics industry, plastic products continue to expand and be used more and more widely in various industries, and the structure of products is becoming more and more complex. There are higher requirements for the precision fit of the mold and the dimensional stability. The complexity of the product directly has higher requirements for the stability of the mold structure. How to ensure the simplicity of processing, the convenience of maintenance, and the rationality of action while simplifying the structure has become a series of research courses. [0003] At present, the mold structure consists of four sliders: conventional slider 1, oil cylinder driven slider 2, front mold core-pulling slider 3, and rear mold core-pulling slide...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a core-pulling structure for the front and rear molds of composite sliders that reduces costs and improves production efficiency, and solves the problem of increasing the thickness of the mold caused by the traditional structure of adding the front film support plate and the rear mold support plate Many, the mold opening action is complicated, the molding cycle will be longer, and the cost of processing and injection molding will increase.
