Slide demoulding mechanism with simple structure

Technical Field

Background

The slide block (slide position) mechanism is very popular in injection mold, and mainly solves the problems of molding and demolding of structural features perpendicular to the mold opening direction on plastic products. In practice, for the slide block (slide position) mechanism driven by the inclined guide post, the moving distance of the slide block (slide position) is in direct proportion to the length of the inclined guide post, the inclined guide post is long, and the moving distance of the slide block (slide position) is long, but the rigidity of the inclined guide post as a cantilever structure can be reduced, and the defects of deformation and fracture increase the daily maintenance cost and directly affect the service life of the die. On the other hand, the inclined guide column is long, the space occupied by the sliding block (row position) mechanism is large, and the die cost is increased.

In addition, the structure of the existing slide demoulding mechanism is complex, and certain parts are required to be replaced integrally after being damaged, so that the maintenance efficiency is low, the maintenance cost is high, and the production progress of products is greatly influenced.

Therefore, the application provides a slide demoulding mechanism with a simple structure, so as to solve the problem.
