[0007] Furthermore, the number of the fixed columns and the sliding blocks are both four, and the number of the moving rods and the springs are both two.

[0008] Furthermore, the shape of the cold air duct is "U"-shaped, the shape of the through seam is "Z"-shaped, a card slot is provided on the upper surface of the base, a card block is installed inside the card slot, the shape and size of the card block are adapted to the card slot, the shape of the card block is "L"-shaped, and the height of the card block is greater than the depth of the card slot.

[0009] Furthermore, the shape and size of the position where the first groove is formed on the fixing rod 1 are adapted to the second groove, and the position where the first groove is formed on the fixing rod 1 is slidably matched with the second groove.

[0010] Furthermore, the lower surface of the fixing plate is slidably connected to the upper surface of the base, the sliders on the side close to the block are slidably connected to the peripheral side of the moving rod, and the sliders on the side away from the block are fixedly connected to the peripheral side of the moving rod.

[0011] The utility model has the following beneficial effects:

[0012] 1. Insert the card block into the card slot to block and fix the fixing plate, and then put the injection molding material into the plastic mold cavity for cooling and molding. Connect a cold air fan at one end of the cold air fan interface, and let the cold air flow into the cold air duct through the cold air fan.
