[0024] The molten plastic is injected into the internal position through the injection hole 8 at the upper end, and the molten plastic fills the mold cavities of the female mold plate 2 and the male mold plate 3. After cooling, the upper ejector plate 7 and the lower ejector plate 6 move upward and downward respectively, so that the molded product is ejected from the mold cavity. The molded product is usually attached to the male mold plate 3. As the mold is opened, the molded product will detach from the mold together with the male mold plate 3, and finally the molded product can be taken out.

[0025] like Figure 3 and Figure 4As shown, the upper fixing plate 1 injects the injection material into the internal position through the injection hole 8 at the upper end position, the connection between the female template 2 and the male template 3 forms a mold cavity, and the mold cavity at the internal position of the female template 2 and the male template 3 is filled with the injection material injected from the injection hole 8.
