Description

Technical Field

[0001] The utility model relates to the technical field of plastic molds, in particular to a plastic mold for an automobile connector. Background Art

[0002] The plastic mold of the automotive connector is a mold used to produce automotive connectors. It is usually made of metal materials such as steel and aluminum, and the internal design of the mold is precisely processed according to the shape and size of the connector. During the production process, plastic particles are injected into the mold and deformed into the shape of the connector through high temperature and high pressure. The final product can be formed and used after cooling and demolding. This mold needs to have the characteristics of high precision, high wear resistance, and high strength to meet the automotive industry's requirements for connector quality and performance;

[0003] In an existing automobile connector plastic mold, the product will fit into the inner wall of the molding cavity after being cooled and formed in the mold, which makes it inconvenient to quickly remove the mold material. When demolding, the plastic mold with a demolding structure on the market needs to separate the movable mold and the fixed mold and then use the demolding mechanism to remove the abrasive from the mold. This process takes a lot of time, which affects the work efficiency. In addition, during use, due to the heavy weight of the movable mold, it is easy to move during repeated opening and closing of the mold, which makes the mold closing inaccurate and reduces the practicality of the mold. For this reason, we propose an automobile connector plastic mold. Utility Model Content
