Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold for the production of automobile parts. Background Art

[0002] The injection mold used in the production of auto parts is a tool specially used to manufacture automobile-related plastic products. It is made of high-strength, wear-resistant materials and can withstand harsh production environments such as high pressure and high temperature. Injection molds can realize the manufacture of complex parts, such as the dashboard and body appearance parts on the car, which require fine injection molds to manufacture. At the same time, injection molds can also realize mass production, improve production efficiency, and meet the market needs of the automotive industry;

[0003] When the injection mold is demolded, the cooperation of the ejector pin is the key to ensure that the parts are smoothly separated from the mold. Although the ejector pin can help the parts to be demolded smoothly in most cases, in some special cases, such as when the parts have a complex structure, a large size or a high material viscosity, the ejector pin may not be able to completely eject the parts from the mold. It can only separate the injection molded parts from the mold, and the parts will remain on the mold. At this time, manual intervention is required to remove the parts from the mold using tools or manual operations, resulting in low demolding efficiency. At the same time, when manually picking up parts from the mold, it will also increase production risks. Utility Model Content
