[0023] The contact plate 7 is installed inside the adapting groove 5. The right side surface of the contact plate 7 is fixedly connected with a boss 8. The left side surface of the contact plate 7 is fixedly connected with a spring body 9 and a telescopic cylinder 10 in sequence from top to bottom. The spring body 9 and the telescopic cylinder 10 are mutually adapted to the limiting groove 6. The lower mold 4 is installed inside the mounting groove 2. The right side surface of the lower mold 4 can be fitted through the anti-slip pad 3 to fix the right side of the lower mold 4. At the same time, when the lower mold 4 enters the mounting groove 2, the boss 8 starts to move to the left, and at the same time, the spring body 9 starts to compress, and the telescopic cylinder 10 limits the spring body 9. At the same time, the spring body 9 and the telescopic cylinder 10 are both installed inside the limiting groove 6, so that the left side of the lower mold 4 is squeezed and limited by the contact plate 7 and the boss 8, and the overall limiting effect is good.

When dismantling it later, it is only necessary to contact the resistance plate 12 to limit the lower mold 4, so the overall installation and disassembly is relatively simple, and it is convenient to replace the lower mold 4.

[0024] Working principle: First, install the lower mold 4 into the inside of the installation groove 2, and the anti-slip pad 3 can fit the right side surface of the lower mold 4 to fix the right side of the lower mold 4. At the same time, when the lower mold 4 enters the inside of the installation groove 2, the boss 8 begins to move to the left, and the spring body 9 begins to compress, and the telescopic cylinder 10 limits the spring body 9. At the same time, the spring body 9 and the telescopic cylinder 10 are both installed in the limiting groove 6, so that the left side of the lower mold 4 is squeezed and limited by the contact plate 7 and the boss 8. The overall limiting effect is good, and the threaded rod 14 can also be twisted. Since the threaded rod 14 is threadedly connected to the bottom plate 1, the threaded rod 14 will drive the contact plate 12 in the groove. 11 moves inside, so that the contact plate 12 will also fit the left side surface of the lower mold 4, so that it only needs to limit and fix the left side of the lower mold 4. When dismantling it later, it only needs to contact the limit of the lower mold 4 by the contact plate 12. The top plate 16 and the cylinder body 17 can be supported by the stabilizing rod 15, and then the cylinder body 17 is started. The connecting plate 18 is driven downward by the cylinder body 17, so that the upper mold 20 can be driven to correspond to the upper surface of the lower mold 4, thereby completing the stamping process of the workpiece of the mounting groove 2. The design of the buffer spring 19 and the telescopic rod 21 can provide a certain buffer during stamping. The above is all the working principles of the present invention.
