However, the above-described die has the following problems:

1. the cavity is usually made integrally with the mold in which it is located, so that when the mold of a different cavity is to be replaced to form the aforementioned product, the entire set of the previously installed molds must be removed from the forming machine, and another mold must be installed in the forming machine. If the whole set of molds must be detached from the forming machine and then mounted in the manufacturing process, the molds usually have a certain weight and volume, and the molds often need to be detached and mounted by means of a hanging tool (such as a bridge crane), so that the problem that the replacement process of the whole set of molds is inconvenient and the efficiency is poor due to the increase of the manufacturing process time is not easy to find.

2. When the existing mold is used for forming materials in a mold cavity, the upper mold and the lower mold are relatively pressed together, so that the situation that the materials are easy to overflow from the space between the upper mold and the lower mold due to the fact that the contact surface of the whole body is not good in tightness is caused, and the qualified rate of finished products is poor.
