[0002] Spring ejector pins are used in automobile molds. Spring ejector pins include a grooved ejector pin body and a retractable ejector with a ball head. When installing, a screwdriver is usually used, because the groove of the ejector pin body There is a certain distance between the ejector and the ejector pin. To install the spring ejector pin, you must use a screwdriver to press the ejector part down so that it can be stuck into the groove, and then apply force to make the spring ejector pin rotate as a whole, and then complete the installation. work; because the ejector part has a strong tendency to eject upward under the force of the spring, so the hand using the tool must keep pressing down until the installation work is completed, which has great installation difficulty and labor intensity ;In addition, the top of the ejector part is a spherical structure. When pressing down with the existing tools, it is in line contact with the spherical surface, which is not easy to locate, and it is easy to slip off. The ejector part is reset. Only when the ejected part is pressed down can the installation work be carried out, which undoubtedly greatly restricts the efficiency of installation
