AI Technical Summary

Technical Problem

After repeated disassembly and reassembly of the mold, the mold and injection head of the existing injection molding machine are prone to misalignment, making it difficult to accurately inject molten plastic into the mold.

Method used

The device employs a combination of a placement plate, clamping components, a positioning frame, and a fixing component. The circular placement slot and cylindrical through slot on the placement plate, in conjunction with the clamping block and the electric cylinder fixing rod, enable precise positioning and fixing of the mold.

Benefits of technology

Ensure that the mold can be accurately placed under the injection head after disassembly and cleaning, avoiding deviation and shaking during movement, and ensuring that the molten plastic is accurately injected into the mold.

Abstract

This disclosure relates to the field of centering adjustment devices. One embodiment of this disclosure provides a centering adjustment device for an injection molding machine's injection stage, which includes a placement plate, a clamping assembly, a positioning frame, and a fixing assembly. The placement plate is mounted on top of a mounting plate via a movable assembly for mounting the mold on the placement plate. The clamping assembly is mounted on the placement plate for clamping and fixing the mold on the placement plate. Two positioning frames are provided, both fixedly mounted on top of the mounting plate. Two fixing assemblies are provided, both mounted on the mounting plate, for fixing the placement plate after it is moved below the injection head. This technical solution solves the problem in the prior art where, after multiple disassemblies and installations of the mold, misalignment easily occurs between the mold and the injection head, making it difficult to accurately inject the molten plastic into the mold.
