Description

Technical Field

[0001] The utility model relates to the technical field of automobile air-conditioning pipeline injection molding, and specifically relates to an automobile air-conditioning pipeline injection molding mold. Background Art

[0002] The injection mold for automobile air-conditioning ducts is a mold specially used for the production of automobile air-conditioning ducts. Its main function is to inject the molten plastic into the mold for cooling and fixing under the action of pressure and temperature, and finally realize the molding of automobile air-conditioning ducts. This mold has many advantages, such as high production efficiency, good production stability and low production cost. By using injection molds, automobile air-conditioning ducts that meet the requirements can be produced on a large scale, quickly and accurately to meet the production needs of the automobile manufacturing industry.

[0003] During the long-term use of the automobile air-conditioning duct injection mold, when the injection plastic liquid flows in the duct, due to the influence of factors such as the roughness, temperature, and pressure of the duct surface, some components in the plastic liquid may adhere to the duct wall. As time goes by, these adhesions will gradually accumulate to form a thicker adhesion layer. The adhesion layer not only affects the flow performance of the plastic liquid in the duct, but also may cause clogging of the duct, affecting the quality and production efficiency of the injection molded product. This adhesion phenomenon not only affects the normal use of the mold, but also increases the difficulty of cleaning and maintenance. Therefore, the technical personnel in this field provide an automobile air-conditioning duct injection mold to solve the problems raised in the above background technology. Utility Model Content
