Description

Technical Field

[0001] The utility model relates to the technical field of water supply and drainage of injection molds, and more specifically, to a water supply and drainage system for injection molds. Background Art

[0002] In the production of injection molded parts, water temperature regulation is usually used to control the mold temperature. Its water supply and drainage system has a vital impact on the normal operation of the mold and the quality of the injection molded products.

[0003] During the injection molding process, after the high-temperature plastic melt is injected into the mold cavity, the water supply system begins to operate. The water pump delivers cooling water through the water supply pipe to the cooling water channel inside the mold. The cooling water flows in the cooling water channel, exchanging heat with high-temperature components such as the mold cavity wall and core. After absorbing heat, the water temperature rises. The cooled cooling water is discharged from the mold through the drainage circuit. After passing through the filter device at the drain outlet to remove impurities, it flows into the cooling tower or heat exchanger for cooling. The cooled water is then pumped back to the cooling water channel of the mold for recycling.

[0004] A Chinese patent application with the patent number CN202321836701.X discloses a water supply and drainage system for injection molds, comprising a water inlet pipe, a water supply pipe, a first return water pipe, a drainage pipe, and a drainage air pipe. The water inlet pipe is connected to the water supply port of the mold temperature controller. This injection mold water supply and drainage system is suitable for mold water supply and drainage in the injection molding manufacturing process. This replaces the traditional drainage method of removing water pipes with a water supply and drainage system that matches the injection mold, making drainage more convenient and more efficient while avoiding the risk of burns, water backflow, and water waste caused by removing water pipes.

[0005] However, it can be seen from the drawings in its specification that the injection mold water supply and drainage system has realized the water supply and drainage of the injection mold, and avoided the risk of scalding, the risk of water backflow and water waste. However, when the water supply and drainage system is installed and used, it needs to be connected to the water pipes around the box frame through a connecting pipe. Most of the existing pipe connections are directly connected by rotating the screw sleeve and the screw head. However, when the water supply and drainage system is started, it will vibrate due to the installation position or internal water flow. Long-term operation will cause the connection of the screw sleeve and the screw head to loosen, affecting the connection sealing effect. Therefore, an injection mold water supply and drainage system is proposed. Utility Model Content
