AI Technical Summary

Technical Problem

In the existing technology, during the demolding process of planetary support, the disk part is prone to deformation, and the upper and lower tube sleeves are difficult to separate from the molding die, resulting in difficulty in mold opening and affecting demolding efficiency and yield.

Method used

The mold adopts a composite demolding mold with secondary ejection and accompanying ejection plate. Through a precise demolding design that is phased and segmented, it utilizes the linkage of elastic elements, guide structures and ejector plate assemblies to achieve separate demolding of the upper tube sleeve, lower tube sleeve and disc part of the planetary support.

Benefits of technology

It effectively avoids product surface deformation and damage, improves demolding yield and efficiency, and optimizes the demolding process.

Abstract

This utility model discloses a composite demolding mold for planetary support with secondary ejection and accompanying ejection plate, comprising an upper mold assembly, a lower mold assembly, a fixed plate assembly, and an ejector plate assembly. The upper mold assembly has an upper forming column, the fixed plate assembly has a lower forming column, and an ejector plate is provided below the upper mold assembly. An elastic element is provided between the ejector plate and the upper mold assembly. The ejector plate has a limiting pin that restricts its downward stroke. The ejector plate assembly has an ejector pin and an ejector rod. The side wall of the lower mold assembly has a receiving groove that houses a slider and a spring. The fixed plate has a guide seat, and a guiding structure is provided between the slider and the guide seat. This design improves the yield rate of demolded products and increases demolding efficiency.
