Gear-driven bent pipe multi-directional demolding mechanism

Abstract

The invention provides a gear-driven bent pipe multi-directional demolding mechanism which comprises a mold frame structure as well as first-position, second-position, third-position and fourth-position core-pulling demolding mechanisms of a core-pulling demolding part, wherein similar oil cylinder driving double-linkage mechanisms serve as the first-position and second-position core-pulling demolding mechanisms; and circular pipe-circular sliding block core-pulling demolding mechanisms serve as the third-position and fourth-position core-pulling demolding mechanisms. The gear-driven bent pipe multi-directional demolding mechanism provided by the invention adopts the above technical scheme and can be applied to a three-way pipe injection mold; accordingly, the complexity and the mold structure of a side core-pulling mechanism at a middle bent pipe part can be simplified when a conventional three-way pipe product adopts the multi-cavity mold design, the reliability of a circular-arc core-pulling mechanism and the mold injection production efficiency can be improved; and the mold production cost can be reduced; and besides, the structural design is reasonable, the structure is compact, the work is stable, and the safety and the reliability are achieved.

Description

technical field [0001] The invention relates to the field of injection mold mechanism design, in particular to a gear-driven elbow multi-directional demoulding mechanism. Background technique [0002] The difficulty of demoulding tee pipe products lies in the core-pulling demoulding of the 90° elbow in the middle part. At the same time, when one mold with multiple cavities is required to improve injection molding production efficiency, the traditional demoulding mechanism is difficult to achieve one mold with multiple cavities, so , it is necessary to design a special core-pulling and demoulding mechanism for the bent pipe to complete the demoulding of the bent pipe and the corresponding mold structure for products with more than two cavities. The principle of production cost, and the simpler its mechanism, the better its reliability and stability. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a gear-driven cu...
