The upper mold 3 and its lower mold 4 can be installed and removed. This is a prior art and no further explanation is given here. A demolding mechanism 5 is arranged on the inner wall of the upper mold 3; the arrangement of the demolding mechanism 5 facilitates the rapid demolding of relevant personnel, and the demolding mechanism 5 includes a connecting spring 504, one end of which is fixedly connected to the inner wall of the upper mold 3, and the connecting spring The other end of 504 is fixedly connected with a movable block 506, and the elasticity of the connecting spring 504 makes the movable block 506 have the reset and limit functions. The outer wall of the movable block 506 is fixedly connected with the extrusion block 505, and the inner wall of the punching machine 1 is fixedly connected with the fixed seat 503, and the fixed seat 503 is L-shaped as a whole. The inner wall of the lower mold 4 is slidably connected with the top plate 501, and the upward movement of the top plate 501 drives the stamped retaining ring to be ejected. The outer wall of the top plate 501 is fixedly connected with the connecting block 502, and the connecting block 502 is provided with two groups located at the left and right ends of the top plate 501. The inner wall of the lower mold 4 is provided with a water cooling mechanism 6, and the water cooling mechanism 6 is used to cool the stamped retaining ring.

[0036] Reference Figure 2-Figure 4 The bottom end of the top plate 501 is fixedly connected with a movable column 507, and the outer wall of the movable column 507 is slidably connected to the inner wall of the lower mold 4. The movable column 507 plays a guiding role, so that after the top plate 501 is pulled out, the top plate 501 can be reset by the setting of the movable column 507, and the outer wall of the movable block 506 is slidably connected to the inner wall of the upper mold 3, and the purpose of convenient demoulding is achieved by sliding. The outer wall of the fixed seat 503 contacts the outer wall of the extrusion block 505, and the contact between the two can make the extrusion block 505 move to release the connection between the movable block 506 and the connecting block 502. The outer walls of the fixed seat 503 and the extrusion block 505 are both triangular in shape, and the outer wall of the movable block 506 is provided with an inclined surface. The triangular shape and the inclined surface are arranged to facilitate extrusion contact, and the outer wall of the movable block 506 is plugged into the inner wall of the connecting block 502. The plugging of the two makes the movable block 506 and the connecting block 502 plug-in and fixed.

[0037] Reference Figure 1 , Figure 5 and Figure 6The water cooling mechanism 6 includes a water storage tank 601, the outer wall of the water storage tank 601 is fixedly connected to the bottom end of the punching machine 1, and the water storage tank 601 plays a fixed supporting role. The inner wall of the water storage tank 601 is fixedly connected with a water storage tank 603 and a water outlet tank 604 respectively. The water storage tank 603 is used to store hot water at the bend of the water pipe 602, and the water storage tank 604 is used to store cooling water. The tops of the two are hollow for heat dissipation. The top of the water storage tank 603 is fixedly connected with a magnetic block 606. The inner wall of the water storage tank 603 is elastically connected with a baffle 605 through a volute spring 608. The baffle 605 is erected for water storage. When the water volume reaches a certain level, the baffle 605 is opened to discharge water into the water outlet tank 604. The top of the baffle 605 is fixedly connected with a magnet 607. The inner wall of the lower mold 4 is fixedly connected with a water pipe 602, and the center of the water pipe 602 is bent.

[0038] Reference Figure 5-Figure 7 The outer wall of the magnetic block 606 is attracted to the outer wall of the magnet 607. When the amount of water inside the water outlet tank 603 reaches a certain level, that is, the amount of water is greater than the magnetic force between the magnetic block 606 and the magnet 607, plus the elasticity of the spiral spring 608, the baffle 605 is opened, and one end of the spiral spring 608 is fixedly connected to the inner wall of the water storage tank 603, and the other end of the spiral spring 608 is fixedly connected to the outer wall of the baffle 605. The outer wall of the baffle 605 is rotatably connected to the inner wall of the water storage tank 603. The elasticity of the spiral spring 608 enables the baffle 605 to have a reset function.

[0039] Working principle: When the relevant personnel need to perform stamping operation on the retaining spring, first place the stamping part on the lower mold 4, then start the stamping machine 1 to make the stamping head 2 move downward, when the stamping head 2 moves downward, it will drive the extrusion block 505 to move downward, and when it moves downward, the inclined surface of the movable block 506 will contact the connecting block 502, so that the movable block 506 and the connecting block 502 are plugged, at this time, the stamping head 2 can perform stamping operation on the stamping part, and at this time, the water pipe 602 on the inner wall of the lower mold 4 will perform a certain cooling operation on the top plate 501, so that the overall working time is shortened, when the stamping is completed, the stamping machine 1 can be started with The movable punch head 2 moves upward, so that the upper mold 3 drives the top plate 501 and the connecting block 502 to move upward together, so that the stamping parts inside the top plate 501 can be brought out, and the relevant personnel can take out the stamping parts, and then continue to move the punch head 2 upward, so that the top inclined surface of the extrusion block 505 contacts the inclined surface of the fixed seat 503, and then the movable block 506 moves, thereby releasing the connection between the movable block 506 and the connecting block 502, and then the top plate 501 will be reset due to its own gravity, so as to facilitate subsequent operations, and the overall demoulding is relatively simple. The contact area with the retaining spring is increased by the setting of the top plate 501 to reduce the damage of the retaining spring.

[0040] Water enters the water pipe 602 from the right end and exits from the left end. When water exits from the left end, it will fall into the inner wall of the water tank 603 for a certain amount of collection, and the opening of the water tank 603 will open to achieve heat dissipation efficiency. When the amount of water on the inner wall of the water tank 603 increases, when it increases to a certain extent, the weight of the water will drive the baffle 605 to flip to squeeze the volute spring 608, thereby allowing the cooling water to be discharged into the water outlet tank 604 for recycling, and then the water is discharged through the water pump inside the water outlet tank 604 for recycling.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
