Background technique

There are many auto parts, among which plastic parts usually need to be processed by injection molds. Injection molds are a tool for producing plastic products, and also a tool for giving plastic products a complete structure and precise size. Injection molding is a processing method used in the mass production of some complex-shaped parts. Specifically, it refers to the high pressure injection of the heated and melted plastic into the mold cavity by the injection molding machine, and after cooling and solidification, a molded product is obtained. And to ensure the molding quality of plastic products, the above-mentioned groove structure is often demolded by the inclined top mechanism. However, during the use of the existing ejector mechanism, most of the ejector rods have an excessively large range of motion, which is easy to cause retraction. It is inconvenient, the device is stuck and the ejector device is scrapped. At the same time, the ejection position of the general ejector device is too small, which will cause product deformation or white surface phenomenon, and the existing ejector device is generally straight upward. Lifting the object is not conducive to the integrity of the demoulding. Therefore, we need to develop an injection mold ejector for automobile parts processing.
