Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to a mold for molding and processing automobile rearview mirrors. Background Art

[0002] In the production process of automobile rearview mirrors, it is often necessary to use an injection mold to perform injection molding on the rearview mirror shell. The Chinese utility model patent, authorization announcement number "CN215589830U", discloses an injection mold for an automobile rearview mirror shell that realizes rapid cooling and molding. A connecting groove is provided inside the lower mold body, and a heat sink is fixedly installed inside the connecting groove. A rectangular frame is fixedly installed on one side of the connecting groove. A rectangular groove is provided on the surface of the rectangular frame, and a connecting frame is slidably connected to the inside of the rectangular groove. A cooling fan is fixedly installed on the inner side of the connecting frame. The surfaces of the lower mold body and the upper mold body are both provided with mounting structures, and a magnetic strip is fixedly installed on the surface of the rectangular frame, so that the staff can control the start of the cooling fan to make the cooling fan draw air to contact the heat sink for heat dissipation, thereby quickly cooling the lower mold body so that the rearview mirror shell can be quickly cooled and molded, reducing the waiting time required by the staff and improving the processing efficiency of the rearview mirror shell.

[0003] The above technical solution is to fit the upper mold body with the lower mold body and then perform injection molding. After the injection molding is completed, the staff can control the heat dissipation fan to start, so that the heat dissipation fan draws air, and the air enters the connecting groove through the rectangular frame, so that the air contacts the heat sink and takes away most of the heat, so that the rearview mirror housing can be quickly cooled and formed. However, the above technical solution still has certain defects. For example, the above equipment performs injection molding after fitting the upper mold body with the lower mold body, and then the heat dissipation fan can speed up the molding. However, when taking out the molding mold, the staff needs to manually take out the model. Due to the interference of human factors, it may cause unstable product quality, such as dimensional deviation, appearance defects, etc., which greatly reduces the production efficiency and quality of the equipment.
