An air supply system for an injection molding machine

Abstract

This utility model discloses an air supply system for injection molding machines, belonging to the field of air supply technology for injection molding machines. The system includes an air storage tank with a sealed top cover fastened to its upper part. A connector is located above the sealed top cover. Connector 1 and connector 2 are welded to the right side of the air storage tank from top to bottom. An inlet pipe and an outlet pipe are connected to the inlet and outlet pipes of external equipment, respectively. Air enters the air storage tank through the inlet pipe and is then discharged through the outlet pipe. By modifying the air supply system, the inlet pipe of the external equipment is cut off, and the air is then connected to the air storage tank before being supplied to the equipment. This avoids the problem of large instantaneous air consumption. Although the air pressure may still fluctuate during production, this system meets production needs and no low-pressure alarms occur, thereby reducing the defect rate and improving production efficiency.

Description

Technical Field

[0001] This utility model relates to the field of air supply technology for injection molding machines, and more specifically, to an air supply system for injection molding machines. Background Technology

[0002] An injection molding machine is an industrial machine used for molding plastic products. It mainly works by injecting molten plastic into a mold, which then cools and solidifies to form the desired product shape. Injection molding machines are widely used in the plastics processing industry and can produce various plastic products, such as bottles, toys, appliance housings, and automotive parts. The air supply system, as part of the injection molding machine, is extremely important.

[0003] Based on the above, the inventors have discovered that: currently, during the production process of the 72 injection molding machine, medium-pressure compressed air is required. Due to the excessively long pipeline from the air compressor room to the production workshop, the injection molding machine consumes a large amount of air instantaneously during production, which leads to insufficient air supply. Therefore, in view of this, the inventors have researched and improved the existing structure to provide an air supply system for the injection molding machine, aiming to achieve a more practical purpose.
