When the mold needs to be replaced, the locking assembly 523 is released, and the lower mold 53 and the mounting assembly 52 can be slid out of the track 51 together.

[0023] The locking assembly 523 includes a connecting plate 231, the outer side of the connecting plate 231 is fixedly connected to the inner side of the base 1, the top of the connecting plate 231 is fixedly connected to a rebound spring 232, the top of the rebound spring 232 is fixedly connected to a locking block 233, the outer side of the locking block 233 is slidably connected to the inner side of the base 1, the top of the locking block 233 is slidably connected to the inner side of the groove 522, the bottom of the locking block 233 is fixedly connected to a movable plate 234, the bottom of the movable plate 234 is fixedly connected to a magnet 235, an electromagnet 236 is provided below the magnet 235, the outer side of the electromagnet 236 is fixedly connected to the bottom of the inner cavity of the base 1, and when in use, the locking block 233 in the locking assembly 523 is fixedly connected to the inner side of the base 1. 33 moves upward under the action of the rebound spring 232 and locks with the groove 522. When the lower mold 53 needs to be replaced, the electromagnet 236 is energized, and the electromagnet 236 drives the magnet 235 to move downward. The magnet 235 drives the movable plate 234 and the locking block 233 to move downward, so that the locking block 233 is away from the groove 522 and released. The locking block 233 compresses the rebound spring 232 on the connecting plate 231. At this time, the old mold is removed and the new mold is moved along the track 51 to the base 1. After the mold replacement is completed, the electromagnet 236 is de-energized, and the locking block 233 moves upward under the drive of the rebound spring 232, gets stuck on the inner side of the groove 522, and locks the sliding plate 521.

The lower mold 53 is installed and positioned by sliding on the track 51 through the installation component 52, and the upper mold 43 is installed and positioned by sliding on the slide groove 42 through the top plate 41;

[0028] When the lower mold 53 needs to be replaced, the electromagnet 236 in the locking assembly 523 is energized, and the electromagnet 236 drives the magnet 235 to move downward, and the magnet 235 drives the movable plate 234 and the locking block 233 to move downward, so that the locking block 233 is away from the groove 522 and the lock is released. The locking block 233 compresses the rebound spring 232 on the connecting plate 231. At this time, the mounting assembly 52 is slid out along the track 51, and the new mold is moved along the track 51 to the base 1. After the lower mold 53 is replaced, the electromagnet 236 is de-energized, and the locking block 233 moves upward under the drive of the rebound spring 232, gets stuck in the inner side of the groove 522, and locks the sliding plate 521.
