Description

Technical Field

[0001] The utility model relates to the technical field of injection molding cooling, in particular to an injection molding cooling mechanism for automobile plastic parts. Background Art

[0002] Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it ejected and fill the mold cavity. After the injection molding is completed, the injection mold needs to be cooled to facilitate demoulding and molding of the injection molded parts.

[0003] Traditional cooling mechanisms can often only adapt to injection molds of specific specifications. When it is necessary to produce automotive plastic parts of different sizes, the corresponding cooling mechanism must be replaced or cumbersome manual adjustments must be made. This limitation seriously affects the flexibility and efficiency of production. For example, after replacing the mold, the staff needs to spend a lot of time and energy to re-adapt the cooling system. Not only is the operation complicated, but it is also prone to inaccurate adjustments, which in turn affects the cooling effect and leads to unstable product quality. In addition, there is a high risk of error when manually adjusting the cooling mechanism. Due to the influence of human factors, improper adjustments may occur, such as the cooling channel not fitting tightly to the mold, uneven distribution of the cooling medium, etc., which may lead to local overheating or overcooling, thereby affecting the molding quality of the plastic parts, and may even cause the generation of waste products, increasing production costs.
