AI Technical Summary

Technical Problem

Existing injection molding machines are usually equipped with only one feeding port. This means that when different raw materials are needed during production, it is necessary to wait for the previous material to be completely in the barrel before the next material can be added, which increases the feeding time cost and reduces production efficiency.

Method used

Design a multi-injection-port injection molding machine that uses multiple raw material tanks and a power shaft transmission system. The mixing and feeding of raw materials are controlled by a stirring rod and a rotating plate, enabling flexible combination and efficient feeding of different raw materials.

Benefits of technology

It improves the material feeding efficiency of injection molding machines. Through the flexible combination of multiple raw material tanks and the control of the power shaft, it provides a suitable ratio of mixed raw materials, shortens the feeding time, and improves production efficiency.

Abstract

This utility model discloses a multi-injection port injection molding machine, including a base plate, an injection section, and a feeding section. The injection section is located on top of the base plate for completing the injection molding operation. The feeding section is located on top of the injection section and has a mixing tank on top of the injection section. The mixing tank has a top cover. A power shaft for stirring the raw materials is rotatably mounted inside the mixing tank. A raw material tank is detachably mounted on the top of the top cover. Several raw material tanks are provided to allow for different quantities of raw materials to be mixed. A transmission shaft for controlling the material discharge is rotatably mounted inside the raw material tank and is meshed with the power shaft. This utility model, by providing a feeding section, makes the material feeding process of the injection molding machine more flexible. Multiple raw material tanks allow for convenient mixing of different quantities of raw materials, and the power shaft drives the transmission shaft to rotate to control the material discharge, providing a suitable ratio of mixed raw materials for subsequent injection molding operations.
