Two positioning slide rods 292 are slidably connected inside the limiting rod 24. The two sides of the positioning slide rods 292 are fixedly connected to the inner cavity of the positioning groove 22. More specifically, the positioning groove 22 is used to accommodate the limiting rod 24, and the positioning slide rods 292 are used to limit the limiting rod 24 to prevent the limiting rod 24 from shaking during movement.

[0028] In some embodiments, a first spring 23 is sleeved on the surface of the positioning slide rod 292, and a fixing rod 25 is fixedly installed on both the front and back of the limiting rod 24. The inside of the fixing rod 25 is connected to a first threaded bracket 26 by a threaded connection. A fixing groove 29 is opened on both the front and back of the connecting rod 291. More specifically, the limiting rod 24 is reset by setting the positioning slide rod 292.

[0029] In some embodiments, the first threaded bracket 26 passes through the connecting rod 291 through the fixing groove 29 on the side that is relatively close to it. The mounting base 28 has four slots 27 on both sides. The fixing rod 25 passes through the mounting base 28 through the slot 27 on the side that is relatively close to it. More specifically, the fixing rod 25 is fixed by setting the first threaded bracket 26 to pass through the connecting rod 291 through the fixing groove 29.

[0030] In some embodiments, the mounting platform 15 has receiving grooves 392 on both sides of its inner cavity. A limiting slider 37 is slidably connected inside the receiving groove 392.

More specifically, by setting the second threaded bracket 39, the limiting slider 37 is fixed through the card holder 391.

[0033] Working principle:

[0034] Step 1: When switching the top mold 21, the first threaded bracket 26 can be rotated. By rotating the first threaded bracket 26, the first threaded bracket 26 is disengaged from the inner cavity of the fixing groove 29, releasing the limit on the connecting rod 291. Then, the fixing rod 25 is pulled outward and disengaged from the inner cavity of the slot 27 to release the limit on the mounting base 28. Then, the top mold 21 is rotated. After rotating to the appropriate position, the fixing rod 25 is released. Under the action of the first spring 23, the limiting rod 24 drives the fixing rod 25 through the slot 27 and into the interior of the mounting base 28, thereby fixing the top mold 21.

[0035] Step 2: After fixing, rotate the first threaded bracket 26. The first threaded bracket 26 passes through the fixing groove 29 and enters the interior of the connecting rod 291. When replacing the bottom mold 31, rotate the second threaded bracket 39 to release the limit on the card seat 391, and then pull it out to replace the limit slider 37. When working, open the cylinder 12 and place the plate in the inner cavity of the limit bracket 32. Finally, with the cooperation of the top mold 21 and the bottom mold 31, turn the hole. When unloading, the second spring 34 causes the push rod 33 to drive the top plate 36 to reset. It has the advantages of easy disassembly and easy unloading.
