System for controlling temperature of plastic part by injection mold

Abstract

The invention discloses a system for controlling a temperature of a plastic part by an injection mold. An injection mold part comprises a main injection mold body and a cooling water pipe arranged in an injection mold, a temperature measurement and control part comprises a wireless thermocouple, a data acquisition module, a controller and a controllable hydraulic pump, the wireless thermocouple is mounted in the main injection mold body and is used for detecting an injection molding temperature, the wireless thermocouple is connected with the data acquisition module, the data acquisition module is connected with the controller, the controller is connected with a controlled end of the controllable hydraulic pump, an inlet of the cooling water pipe is connected with an outlet of the controllable hydraulic pump, an inlet of the controllable hydraulic pump is connected with an outlet of a cooling water tank, an outlet of the cooling water pipe communicates with a water return opening of the cooling water tank, and the controller comprises a temperature control module used for controlling different flow speeds of cooling liquid of the controllable hydraulic pump according to a received injection molding temperature and an injection molding working state. According to the system, the temperature is effectively controlled, a yield is increased, and meanwhile the production efficiency is improved.

Description

technical field [0001] The invention belongs to injection mold production equipment, and relates to a system for controlling the temperature of plastic parts of an injection mold. Background technique [0002] With the progress of mold design and processing level, mold products have been widely used in social production and life. Molds include injection molds and stamping molds. The rapid increase in demand for plastic products has brought about the rapid development of injection molds. Injection mold is a tool for producing plastic products, and injection molding is a processing method used in mass production of certain complex-shaped parts. The molded product is obtained by injecting the heated and melted plastic into the mold cavity under high pressure from the injection molding machine, and cooling and solidifying. The injection mold consists of a moving mold and a fixed mold. The moving mold is installed on the movable template of the injection molding machine, and t...

AI Technical Summary

Problems solved by technology

[0003] During the molding process, there is no way to control the temperature of the plastic parts, which will cause problems such as air pockets, bubbles, and cracks in the finished product

After molding, it is generally taken out by air cooling to a suitable temperature. This situation will result in low production efficiency. The temperature taken out generally depends on the experience of the operator, which may cause trouble for subsequent processing or pose a hidden danger to the safety of the operator.
