AI Technical Summary

Technical Problem

The mold and demolding mechanism of existing injection molding demolding devices are separately designed functional modules, which results in high demolding costs and requires close coordination, increasing the difficulty of operation.

Method used

The injection mold's movement and demolding functions are integrated into a single drive system by a servo motor-driven threaded shaft and a linkage ejector mechanism. The mold's closing and opening actions are achieved through a threaded plate and connecting rod, and a fixed spring provides elastic force to push the ejector plate to eject the molded part.

Benefits of technology

It integrates the injection mold and the demolding mechanism, reducing manufacturing costs and operational complexity, improving demolding efficiency and stability, and simplifying the operation process.

Abstract

This utility model discloses a demolding device for injection molded parts, belonging to the field of demolding technology for injection molded parts. The device includes an injection platform, a first support plate vertically fixed to the top side of the platform, a servo motor fixedly mounted on the middle of one side of the first support plate, the output end of the servo motor connected to a threaded shaft via a coupling, and a second support plate rotatably connected to the end of the threaded shaft away from the servo motor via a bearing. The bottom side of the second support plate is fixedly connected to the injection platform, a threaded plate vertically threaded onto the threaded shaft, and a connecting rod fixedly connected in a rectangular array to one side of the threaded plate. The connecting rod passes through the second support plate and is located away from the threaded shaft. An injection mold is vertically fixed to the end of the first plate. A pusher shaft is horizontally slidably connected through a rectangular array in the middle of the second plate. A limit plate is vertically fixed to the middle section of the pusher shaft. The end of the pusher shaft away from the threaded plate passes through the injection mold and is vertically fixed to a pusher plate. The pusher plate is fitted into the inner wall of the injection mold. The part of the pusher shaft between the injection mold and the limit plate is wrapped with a fixing spring. The two ends of the fixing spring are fixedly connected to the injection mold and the limit plate, respectively. This utility model can integrate the injection mold and the demolding mechanism, effectively reducing the cost and difficulty of demolding injection molded parts, which has certain practicality.
