[0002] Molds are various molds and tools used in industrial production to obtain the desired products through methods such as injection molding, blow molding, extrusion, die casting or forging, smelting, and stamping. Molds can achieve mass production of products, greatly improving production efficiency. Compared with traditional manual production, mold production can produce a large number of products of the same specifications in a short time.

[0003] When the mold is in use, it is usually fixed in a suitable position by a mold frame so that the mold can be used for injection molding and stamping production. However, during production, if the mold is damaged or needs to be replaced with a different mold, the mold frame and the mold need to be removed and replaced. The operation is cumbersome and the replacement is troublesome. It is not possible to replace it quickly, so that in the case of continuous production, it is difficult to resume production as soon as possible.
