The ejector block 32 is movably disposed in the second opening 13.

[0060] When gas is introduced into the cavity 11, the ejection plate 31 moves in a direction away from the first opening 12, that is, moves in a direction toward the second opening 13, and the ejection plate 31 drives the ejection block 32 to move away from the first opening 12 in the second opening 13, so that the workpiece 201 located in the second opening 13 is ejected.

[0061] The mold 100 provided in the present application pushes the ejection plate 31 through gas to move it toward the second opening 13, thereby automatically ejecting the workpiece 201. The entire process reduces manual intervention, reduces the need for manual operation and related costs. At the same time, the automated ejection process can ensure that each of the workpieces 201 is ejected stably, avoiding the inconsistency that may be caused by manual operation. Furthermore, the force and speed of ejection can be precisely controlled by controlling the gas, reducing the damage to the workpiece 201 that may be caused by manual operation, which is beneficial to improving the integrity and quality of the product.

[0062] In this embodiment, the first mold frame 10 includes a first pad 14, a fixed plate 15, a first clamping plate 16 and a first template 17.

[0070] S1: Open the mold 100 to separate the first mold frame 10 and the second mold frame 20, then place the workpiece 200 on the second mold frame 20 and complete the alignment.

[0071] S2: The first mold frame 10 is moved toward the second mold frame 20, and the first template 17 and the second template 24 clamp the non-stamping area 200b. At this time, the elastic member 25 pushes the second template 24 and the second clamping plate 23 to be spaced apart.

[0072] S3: Continue to move the first mold frame 10 toward the second mold frame 20, and the punching block 21 punches the punching area 200a until the punching area 200a is punched into the groove 131 to form the workpiece 201. At this time, the elastic member 25 is not sufficient to push the second template 24 and the second clamping plate 23 to be separated, the distance between the second template 24 and the second clamping plate 23 becomes smaller, and the second ejector column 26 pushes the first ejector column 18, so that the ejector block 32 moves toward the first opening 12.

[0073] S4: Open the mold 100 again, so that the first mold frame 10 and the second mold frame 20 are separated again, and then a material tray 300 is inserted between the first mold frame 10 and the second mold frame 20, and the material tray 300 and the workpiece 201 located in the groove 131 are aligned.

[0074] S5: Gas is introduced into the cavity 11 through the first opening 12, so that the top material block 32 moves toward the groove 131, then enters the groove 131 and pushes the workpiece 201 to fall into a predetermined position of the material tray 300, and then the material tray 300 carrying the workpiece 201 is removed.
