The opposite side of the electromagnetic block 402 and the magnets 4023 on both sides are of different poles. Because the electromagnetic block 402 is started, the magnet 4023 is driven to move under the principle of attraction between different poles, so that the magnet 4023 drives the locking plug plate 4025 to move. Then, the snap-fitting plate 302 is inserted into the snap-fitting slot 4011 to make the two sets of molds match each other, and then the electromagnetic block 402 is closed. When the magnet 4023 moves, the spring 4022 is squeezed on the outside of the fixed cross bar 4021, so that the spring 4022 produces elastic deformation, so that the spring 4022 pushes the magnet 4023 to move, so that the magnet 4023 drives the locking plate 4025 to reset and insert it into the locking slot 3021, so as to prevent the mold from loosening when closing the mold, improve the accuracy of closing the mold, and avoid defective products.

[0039] The specific usage and function of this embodiment are as follows:

[0040] In the present invention, the lower mold structure 3 is placed on the mounting recess 201, and then the rotating handle 2022 is rotated to drive the bidirectional screw rod 202 to rotate, and then the bidirectional screw rod 202 is rotated and engaged with the threaded hole 2041 on the movable belt ring 204, but the movable belt ring 204 is limited and guided on the guide rod 203 by the guide ring 2042, so that the bidirectional screw rod 202 drives the two groups of movable belt rings 204 to move in reverse, so that the movable belt ring 204 drives the installation plug 2045 to be inserted into the installation plug hole 3011 through the fixed vertical plate 2044, and the installation of the lower mold structure 3 is completed. When disassembling, it is only necessary to rotate the rotating handle 2022 in the opposite direction, and the movable belt rings 204 on both sides are driven to move toward each other under the action of the bidirectional screw rod 202, so that the movable belt ring 204 drives the installation plug 2045 to disengage from the installation The socket 3011 is opened, and the disassembly of the lower mold structure 3 is completed. The operation is simple, easy to disassemble and replace, and the work efficiency is improved. Then, the electromagnetic block 402 is started to drive the magnet 4023 to move under the principle of opposite poles attracting each other, so that the magnet 4023 drives the locking plug plate 4025 to move, and then the snap-fit ​​plug plate 302 is inserted into the snap-fit ​​slot 4011 to make the two sets of molds fit together. Then the electromagnetic block 402 is closed, and when the magnet 4023 moves, the spring 4022 is squeezed on the outer side of the fixed cross bar 4021 to make the spring 4022 produce elastic deformation, so that the spring 4022 pushes the magnet 4023 to move, so that the magnet 4023 drives the locking plug plate 4025 to reset and insert it into the locking slot 3021, so as to prevent the mold from loosening when closing the mold, improve the accuracy of closing the mold, and avoid defective products.
