A plurality of forming holes 82 are opened on both sides of the downflow channel 81. The forming holes 82 are evenly arranged and penetrated on the rear mold panel 8. The set forming holes 82 can form multiple products for batch production, thereby improving production efficiency.
[0024] In addition, the downflow channel 81 includes a guide channel 811, which guides to one side of each molding hole 82. An injection hole 812 is opened in the downflow channel 81, and the injection hole 812 is connected to the injection pipeline of the plastic mold. The guide channel 811 facilitates the uniform introduction of the injection material into the molding hole 82, prevents excessive injection molding material, and can effectively save costs.
