[0003] Ejector plate. This is the main part of the mold ejector plate, usually composed of a steel plate and a support frame. It is equipped with multiple ejectors, which are used to control the opening and closing of the mold. The structure of the ejector plate ensures that the mold can perform injection molding or die casting in a closed state to achieve the molding of parts.

[0004] Needle holder. This is a fixture on the ejector plate, usually made of steel or copper. Its function is to place the ejector in a fixed position to ensure that the part can be ejected accurately.

[0005] Ejector. This is one of the important parts of the mold ejector plate, mainly made of steel with high surface quality requirements. The function of the ejector is to push the mold top plate open during injection molding or die casting, so that it can be opened and quickly recovered to achieve the molding of the part. When designing, it is necessary to select ejectors of different diameters and lengths according to the specific mold requirements, and ensure that their surface is smooth without any scratches, cracks and other defects.

[0006] Spring. This is one of the important parts connecting the ejector pin and the ejector plate. Its main function is to adjust the extension and contraction of the ejector pin, keep the ejector pin in a predetermined position, and absorb impact and noise during the opening and closing of the mold.

[0007] The existing mold ejector plate is inconvenient to install and disassemble, the operation steps are cumbersome, and there is a problem of occupying a large space. Utility Model Content
