[0027] The connection mechanism is used to enable the inflation mechanism to squeeze the air in the air chamber 7 into the two cavities, and then discharge it through each air outlet, so that the workpiece can be blown out, effectively reducing the possibility of workpiece damage.

[0028] In order to make the workpiece can be blown out, such as Figure 1 As shown, the connecting mechanism includes a first air pipe 8, a three-way joint 9 and two second air pipes 10, a first through hole is opened on the inner wall of the air chamber 7, one end of the first air pipe 8 is fixedly sleeved inside the first through hole, second through holes are opened on the inner walls of the two cavities, the two second air pipes 10 are respectively fixedly sleeved inside the corresponding second through holes, the three joints of the three-way joint 9 are respectively fixedly sleeved on the pipe walls of the first air pipe 8 or one end of the two second air pipes 10, the inflation mechanism includes two connecting rods 11 and a piston 12, the two connecting rods 11 are respectively fixedly connected to the upper surfaces of the two ends of the upper mold 5, the two connecting rods 11 successively penetrate the mounting plate 3 and the lower surface of the air chamber 7 and extend to the inside of the air chamber 7, the piston 12 is fixedly connected to the upper ends of the two connecting rods 11, and the piston 12 matches the air chamber 7.

[0029] When the workpiece is plasticized, the cylinder 4 is started so that the upper mold 5 and the lower mold 6 can be separated, and the two connecting rods 11 are driven to move upward. Then the piston 12 can discharge the air in the air chamber 7 into the interior of the two cavities through the first air pipe 8 and the two second air pipes 10, and then discharge it through each air outlet, so that the workpiece can be blown out.

[0030] In order to prevent the casting liquid from flowing into the cavity, Figure 2-3 As shown, a first one-way valve 13 is disposed inside each air outlet.
