According to the shape of the product, deep holes can be set in the male mold core 51 and the female mold core 52 to pass coolant to accelerate the cooling and solidification of the product.

[0048] like Figure 1 As shown, the ejection module 8 includes an ejection plate 81, an ejection fixing plate 82, an ejector pin 83 and a guide rod 84. The ejector plate 81 is provided with a plurality of ejector pins 83 and a plurality of guide rods 84. The ejector pins 83 and the guide rods 84 pass through the ejection plate 81 and the movable mold plate 4 in sequence. The bottom of the ejector plate 81 is fixedly connected to the ejection fixing plate 82, and the bottom surface of the ejector fixing plate 82 is in contact with the mold base 7.

[0049] The ejector plate 81 is used to fix the ejector pin 83 and the guide rod 84. The ejector fixing plate 82 prevents the ejector pin 83 and the guide rod 84 from detaching from the bottom of the ejector plate 81. When demolding, the ejector pin 83 penetrates into the male mold core 51 to eject and separate the product. A spring is inserted into the guide rod 84 to reset the ejector plate 81.

[0050] The working principle of the present invention is as follows: the injection nozzle passes through the positioning ring to pass the plastic melt to the shovel base, the shovel base evenly sends the plastic melt into the cavity module, and then passes the coolant to cool and solidify, the fixed template is fixed to the support seat through the pad and the fixed block, the shovel base is fixed to the mold frame fixed plate, and after solidification is completed, the injection molding machine separates the fixed template from the movable template, and then controls the injection molding machine to press the ejector plate, so that the ejector pin passes through the male mold core to eject and separate the product.
