The piston rod of the cylinder 122 extends and pushes the moving block 123 to move. The moving block 123 pushes the third forming block 13 to the second casting station 7. After closing, the first casting station 6 and the second casting station 7 form a casting cavity. The casting block 24 connects with the casting pipe 251. The casting equipment connects with the casting mold through the casting pipe 251 to pour the casting liquid. The casting liquid enters through the casting pipe 251 and flows along the guide channel 30 of the casting section to the main channel 31. When it reaches the branch channel 32, it is guided to the inlet groove 33 through the branch channel 32. The casting liquid enters the casting cavity through the inlet groove 33 and is cast. After the casting liquid enters the casting cavity and the workpiece is cooled and formed, the fixed mold frame 2 and the moving mold frame 3 are opened. The return springs 83 on both sides extend and push the pull rod 82 to return to its original position. The two pull rods 82 pull the two connecting blocks 9 respectively. The two connecting blocks 9 move away the first forming block 10 and the second forming block 11 respectively. Then, the cylinder 122 is driven. The piston rod of the cylinder 122 retracts and moves away the third forming block 13 through the moving block 123, reducing the area during each demolding and thus reducing the force required for demolding, making it easier for the workpiece to be demolded.
