[0024] like Figures 1 to 4As shown, by setting a plurality of (4 in the present application) molding cavities between the upper template 4 and the lower template 5, more products 21 can be injected simultaneously. When the product 21 is demolded, the product 21 can be automatically ejected from the module 7 of the lower template 5 by the movement of the ejector plate 9, thereby realizing automatic demolding of the product 21 and improving production efficiency.

[0025] like Figure 4 and Figure 5 As shown, in the present embodiment, preferably, a first fixed block is provided on the ejection plate 9, and a first inclined ejection rod 12 is slidably connected to the first fixed block.
