The second mold 300 refers to another part of the main structure for molding the work, and the second mold 300 is detachably connected to the base 100. The material of the second mold 300 is similar to that of the first mold 200, and will not be described here. The second die 300 in the embodiment of the present application is exemplified by the same carbon steel material as the first die 200.

The second mold 300 is disposed opposite to the first mold 200 in the first direction Z. The first direction Z may be a horizontal direction, a vertical direction, or an oblique direction, depending on the actual situation. For ease of understanding and description, some embodiments of the application are illustrated with respect to the vertical direction.

Before the workpiece is formed, the movable die 210 needs to be rotated in a direction approaching the second die 300 to close the die 10 to form a cavity. When the mold needs to be opened, the movable mold 210 needs to be rotated in a direction away from the second mold 300 to open the mold 10.

But after accomplishing the pressure release unblock movable mould 210 and make movable mould 210 rotate along the direction that deviates from second mould 300 and open, for the direct open mould's of not pressure release situation, its process of this scheme adoption initiative pressure release scheme is gentler, and less to the influence of product in the die cavity to can ensure the quality of product, promote the yields of product. When the mold 10 needs to be operated again, the transmission assembly 400 only needs to drive the movable mold 210 to move to the first position along the opposite direction of the first direction Z, that is, the movable mold 210 abuts against the second mold 300 to form a mold cavity. The whole operation is convenient and quick, and the production efficiency of the die 10 can be improved. Compared with the scheme that the movable die 210 is directly far away from the second die 300 to take out a workpiece, the moving distance of the movable die 210 is shorter during pressure relief, so that the moving precision of the die 10 can be ensured, the abrasion of the die 10 is reduced, and the production cost is saved.

The drive assembly 400 is configured to enable the mold frame 220 to move toward or away from the second mold 300 in the first direction Z. And because the driving piece 410 passes through the platform, the platform can realize the guiding function on the driving piece 410, and the shaking of the mold frame 220 in the moving process is reduced.

In some embodiments, the drive 410 is driven in a range of 0mm to 10mm. I.e. the mold frame 220 can move 0mm to 10mm in the first direction Z. It should be noted that, the external controller 800 may control the movement stroke of the driving member 410, and different movement strokes may be set according to actual needs. The external controller 800 can realize the automatic control of the driving member 410, and improve the production efficiency. Compared with the scheme that the movable die 210 is directly far away from the second die 300 to take out a workpiece, the moving distance of the movable die 210 is shorter during pressure relief, so that the moving precision of the die 10 can be ensured, the abrasion of the die 10 is reduced, and the production cost is saved.

Referring to fig. 2 to 5, the mold 10 further includes a locking member 600. In some embodiments, retaining member 600 may be configured as an elongated shape. In other embodiments, the locking member 600 may be configured as an oval, as the case may be. The locking member 600 in this embodiment is exemplified by a strip-shaped structure.

It should be noted that the second peripheral portion 222 of the mold frame 220 may be a peripheral portion of the mold frame 220 for accommodating the internal notch of the movable mold 210. The specific structure of the latch 223 depends on the structural shape of the latch 212. It is understood that the depth of the slot 223 should be smaller than the thickness of the mold frame 220, so that the clamping block 212 can penetrate the slot 223 when the movable mold 210 is in the first position, i.e. the mold frame 220 can support the clamping block 212 through the slot 223 and limit the movable mold 210 to move toward the second mold 300.

In some embodiments, retaining member 600 is rotatably coupled to mold frame 220, i.e., retaining member 600 may rotate relative to mold frame 220. Referring to fig. 2, in the third position, the locking member 600 abuts the movable die 210 in the first direction Z, that is, the displacement of the movable die 210 is limited. Referring to fig. 3, in the fourth position, the locking member 600 is rotated to a portion other than the movable mold 210 so that the movable mold 210 can be freely rotated. The locking member 600 is turned to switch the first position and the second position of the movable mold 210, so that the operation is convenient and fast, and the production efficiency can be greatly improved.

Referring to fig. 2, a plurality of locking members 600 may be provided, and the specific number may depend on the actual situation, and three locking members 600 are taken as an example in the embodiment of the present application. The plurality of locking members 600 are spaced apart along the circumferential direction of the mold frame 220.
