Description

Technical Field

[0001] The utility model relates to the technical field of automobile plastic parts processing, in particular to an adjustable automobile plastic parts forming die. Background Art

[0002] Automotive plastic parts refer to various types of plastic products used in automobile manufacturing, which can be divided into interior parts, exterior parts and functional parts.

[0003] After searching, it was found that the Chinese patent announcement number CN218196613U discloses a mold for forming automobile plastic parts. The device pushes out the injection molded parts through a pushing mechanism, which makes it easier for users to take them out during use. The cooling component sprays the coolant on the lower mold, which can quickly cool the lower mold. This solves the problem that the existing injection mold is very inconvenient when taking out the injection molded parts, resulting in a long time to take out the injection molded parts during use, which not only reduces production efficiency but also wastes time and effort. However, the applicability of this device is limited. It can only process fixed-structure plastic parts that match the lower mold and upper mold. In the automotive field, the structures of plastic parts are different, and the corresponding devices need to be frequently replaced to achieve the processing effect, which increases the processing cost and the complexity of operation. Therefore, it is necessary to improve the existing device to meet actual needs. Utility Model Content
