[0021] The utility model provides Figure 1-5The post-mold locking structure shown in the figure includes a lower mold 100, and the lower mold 100 is also provided with an upper mold that can move up and down, and the lower mold 100 is provided with a detachable mold cavity. After the mold cavity is placed on the lower mold 100 and locked in position, the upper mold descends and is molded with the lower mold 100 to carry out the molding processing of the blank. A lock tongue seat 200 that can move horizontally along the upper surface of the lower mold 100 is provided above the lower mold 100. The side of the lock tongue seat 200 away from the guide block 300 is in the shape of an inclined surface, and the end of the lock tongue seat 200 away from the top block 500 is provided with a tongue body protruding outwards. The tongue body protruding outwards at the side wall of the lock tongue seat 200 can be moved horizontally by the lock tongue seat 200. , the mold cavity on the lower mold 100 is locked or unlocked by snapping, and the lower mold 100 is provided with a driving mechanism that can be lifted vertically, which is used to drive the lock tongue seat 200 to move horizontally, and the driving mechanism is fixedly connected to the upper mold. The upper mold can be lifted and lowered on the lower mold 100 to realize the process of mold closing or mold parting, and the driving mechanism can be driven to lift and lower, and the lock tongue seat 200 can be driven to move horizontally during the lifting process of the driving mechanism. In this way, the upper mold can drive the lock tongue seat 200 to move horizontally during the process of mold closing or mold parting, so that the upper mold can lock or unlock the upper mold cavity of the lower mold 100 at the same time during the process of mold closing or mold parting, making the use of the mold more flexible and convenient.

[0022] In one embodiment, the driving mechanism includes a guide block 300, and an inclined through hole 201 with inclined inner walls on both sides is opened at the end of the lock tongue seat 200. The outer wall of the guide block 300 is movably plugged into the inner side of the inclined through hole 201. When the guide block 300 moves up with the upper mold, the inclined surface of the guide block 300 and the inclined through hole 201 on the lock tongue seat 200 can be movably interlaced and matched, so that the guide block 300 moves up and drives the lock tongue seat 200 to move horizontally to the left. When the guide block 300 moves down, the lock tongue seat 20 0 moves horizontally to the right; further, the guide block 300 includes a connecting portion 301 and an inclined column portion 302, the inclined column portion 302 is fixedly connected to the bottom end of the connecting portion 301 in an inclined shape, the outer wall of the inclined column portion 302 is movably plugged into the inner side of the inclined through hole 201, and the inclined column portion 302 cooperates with the connecting portion 301, which can not only limit the downward position of the guide block 300, but also drive the lock tongue seat 200 to move horizontally during the vertical lifting process, so that the locking of the mold cavity after the upper mold and the lower mold 100 are closed is more flexible and convenient, and the degree of automation is high.
