Since the top surfaces of the first mold body 1 and the second mold body 2 are opposite to each other, the edges of the top surfaces of the first mold body 1 and the second mold body 2 are opposite to each other. An injection hole 10 is opened at the center of the edge, and the injection hole 10 penetrates the top surface of the adjusting mold male mold 12. Since there are multiple adjusting mold male molds 12, the shapes of adjacent adjusting mold male molds 12 are different, and the adjusting mold male molds 12 and the adjusting mold female molds 11 are grouped and correspond to each other. According to the needs of the actual molding shape of the shell, the corresponding adjusting mold male mold 12 and the adjusting mold female mold 11 are selected, and the selected adjusting mold male mold 12 and the adjusting mold female mold 11 are engaged with the mounting adjustment grooves 9 on the surfaces of the first mold body 1 and the second mold body 2, and then the adjusting mold male mold 12 and The female mold 11 of the adjusting mold is molded, and the first mold body 1 and the second mold body 2 are molded together. After the mold is molded, the molten liquid of the plastic shell can be injected through the injection hole 10, and the injected liquid flows along the inner wall of the male mold 12 of the adjusting mold and the outer wall of the female mold 11 of the adjusting mold, covering the entire surface of the female mold 11 of the adjusting mold, and forming a shell structure after cooling. After cooling, the first mold body 1 and the second mold body 2 are demolded and separated in turn, and then the male mold 12 of the adjusting mold and the female mold 11 of the adjusting mold are demolded and separated, and the shell is taken out, and the injection of the shell is completed.
