Double core pulling linkage mechanism of oil cylinder

Abstract

The invention discloses a double core pulling linkage mechanism of an oil cylinder. The double core pulling linkage mechanism comprises a first core pulling device, a second core pulling device and an oil cylinder linkage device, wherein the first core pulling device and the second core pulling device are fixedly arranged on the oil cylinder linkage device through screw threads. According to the mechanism disclosed by the invention, twice core pulling actions can be completed in a demoulding process, the fully automatic production is adapted, the labor is saved, the cost of production is reduced, and the dimensional accuracy of a mold part is improved.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to an oil cylinder double core-pulling linkage mechanism. Background technique [0002] The product structure of injection molded parts is becoming more and more complex, which leads to the fact that the conventional mold structure design cannot meet the existing injection molded parts. In the usual injection mold structure, if the structure of the product is complex, two slider core-pulling structures are required. The usual practice is to first put the insert into the conventional slider core-pulling demoulding, and then manually remove the parts The inserts are shared with the plastic parts. This operation method not only requires more manual operations, but cannot adapt to fully automatic production, but also reduces the dimensional accuracy of plastic parts due to manual operations and reduces the product qualification rate.

[0002] The product structure of injection molded parts is becoming more and more complex, which leads to the fact that the conventional mold structure design cannot meet the requirements of existing injection molded parts.

In the usual injection mold structure, if the structure of the product is complex, two slider core-pulling structures are required. The usual practice is to first put the insert into the conventional slider core-pulling and demoulding, and then manually remove the parts. The inserts are shared with the plastic parts. This operation method not only requires more manual operations, but cannot adapt to fully automatic production. It will also reduce the dimensional accuracy of the plastic parts and reduce the product qualification rate due to manual operations.
