Description

Technical Field

[0001] The utility model relates to the technical field of hot runners, in particular to a hot runner system for automobile injection molds. Background Art

[0002] The hot runner ensures that the plastic in the runner and gate remains in a molten state by heating. The hot runner system is generally composed of several parts such as a hot nozzle, a manifold, a temperature control box and accessories. There are generally two types of hot nozzles: an open hot nozzle and a needle valve hot nozzle. Since the form of the hot nozzle directly determines the selection of the hot runner system and the manufacture of the mold, the hot runner system is often divided into an open hot runner system and a needle valve hot runner system. Since the existing technology cannot ensure that the material is always in a molten constant temperature state, the temperature is too high, causing the physical properties of the molten material to change or the molten material to solidify, thereby affecting the production quality of the product. Therefore, patent CN215791445U proposes "A hot runner system for an automotive sealing strip injection mold". The PLC controller integrates and analyzes data information to control whether the heating wire is working, thereby ensuring that the material is always in a molten state, avoiding excessive temperature that causes changes in the physical properties of the molten material or solidification of the molten material, thereby affecting the production quality of the product.

[0003] However, this solution does not have the function of filtering the fluid. Impurities and particles in the molten glue will affect the quality of the product after molding. In addition, the PLC controller and temperature sensor in this solution can only monitor the fluid temperature and control whether the heating wire is working. However, if the heating component is damaged, it cannot issue an alarm to alert the staff, which will increase the product defective rate. For this reason, a hot runner system for automotive injection molds is proposed. Utility Model Content
