Background
In the machining of the injection mold, various numerical control machining is available, the numerical control milling and machining center is most applied, the numerical control wire cutting machining and the numerical control electric spark machining are very commonly applied to the numerical control machining of the mold, and the wire cutting is mainly applied to the machining of various straight-wall molds, such as a concave-convex mold in stamping, an insert and a slide block in an injection mold, an electrode for electric spark machining and the like. For the die parts with high hardness, the machining method cannot be used for machining, electric spark machining is mostly used, and electric spark machining is also used for sharp corners, deep cavity parts, narrow grooves and the like of a die cavity.

In the die machining, the application of the numerical control drilling machine can also play a role in improving the machining precision and shortening the machining period. The thimble is a plastic mould accessory and is used in a plastic mould. The thimble may be a push rod, an insert needle, a middle needle, a support needle, etc., and sometimes a tip for a lathe is also called a thimble. In plastic molds, it is also most common to separate the product from the mold; the hard alloy thimble such as a tungsten steel thimble can be used for passing a longer and thinner hole; the ejector pin, also called the tip, is a conical metal round bar with a conical head, which is assembled on a lathe or a grinding machine and used for supporting and rotating a workpiece around the workpiece, but is completely different from the ejector pin of a plastic mold accessory; the plastic mould thimble can also be used in the mould, and it can play a firm effect, is called to inlay the needle. The ejector pin panel and the ejector pin of the existing injection mold are inconvenient to assemble accurately, and the assembly operation efficiency is low.
