AI Technical Summary

Technical Problem

Existing methods for removing material edges from blow-molded parts cannot effectively remove hidden material edges at the root. Furthermore, the separate design of the blow molding material pick-up and edge removal mechanisms results in complex structures, large floor space requirements, and makes them unsuitable for high-speed production.

Method used

A compact blow-molded part removal and blanking edge removal device was designed. It adopts a molded part removal mechanism, a blanking edge removal mechanism and a molded part conveying mechanism. The edge is completely removed by clamping and lateral movement. The removal and edge removal operations are integrated, simplifying the structure.

Benefits of technology

It achieves complete removal of material edges, simplifies the operation process, improves production efficiency, and is suitable for high-speed multi-mold blow molding production.

Abstract

The application relates to a device for taking out blow-molded parts and removing the lower edge, characterized in that the taking-out mechanism of the molded parts comprises a linear module, a cantilever arm and a receiving groove, which is used for receiving the molded parts falling from the mold opening mechanism after the mold is opened and conveying the molded parts to the lower working position; the removing mechanism of the lower edge is arranged on the right side of the receiving groove at the lower working position and comprises two groups of oppositely arranged molded part pressing assemblies and two groups of oppositely arranged edge removing assemblies; the base plate is provided with a hollow hole for the lower edge to pass through, and the waste output mechanism is arranged below the hollow hole; the conveying mechanism of the molded parts adopts a belt conveying mechanism arranged along the left and right sides, and the conveying belt is arranged in a side-standing mode, which is used for conveying the molded parts moved to the lower working position by the taking-out mechanism of the molded parts to the removing mechanism of the lower edge, conveying the molded parts with the lower edge removed to the inlet end of the terminal output mechanism, and realizing the output of the molded parts. The application has compact structure and is suitable for high-speed multi-mold blow molding production.
