Description

Technical Field

[0001] The utility model relates to the technical field of injection molding devices, in particular to an injection molding device for producing automobile air conditioners. Background Art

[0002] Injection molding equipment plays a vital role in the production of automotive air conditioning system components. This type of equipment is mainly used to produce various plastic parts, such as air ducts and housings in air conditioning systems. The injection molding process is an efficient manufacturing technology that can mass-produce plastic parts with complex shapes and precise dimensions. In traditional injection molding equipment, the hot melt end is mainly responsible for providing the hot melt function, that is, the plastic particles are heated by the heater, and through the rotation and advancement of the screw, the plastic particles are heated and melted into hot flow plastic at the hot melt end. Then, the molten plastic is injected into a precisely designed mold, where it is cooled and solidified into the desired shape of the component. The efficiency and repeatability of this process make it an ideal choice for manufacturing automotive air conditioning system components.

[0003] However, the current injection molding devices have certain limitations when heating plastic particles. The heating process of plastic particles is from the outside to the inside, which requires a certain amount of time for the heat to gradually penetrate into the interior of the particles. The limitation of this heating method is that relying solely on traditional heating methods can easily lead to uneven heating of plastic particles. If the plastic is not heated and melted evenly, problems may occur during the injection molding process, such as unmelted particles inside the plastic parts, insufficient melt fluidity, and internal stress and poor surface quality in the molded products. These problems will directly affect the performance and appearance quality of the product, and may even lead to the scrapping of the product.
