DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0029] Example 1

[0030] The present invention provides a power supply housing stamping die that is easy to demould, such as Figures 1 to 7 As shown, it comprises: a lower die base 1, a plurality of hydraulic rods 2 are fixedly installed at the four corners of the top of the lower die base 1, an upper die base 3 is installed between the tops of the plurality of hydraulic rods 2, a concave die fixing plate 4 is fixedly installed at the bottom of the upper die base 3, a concave die pad 5 is fixedly installed at the middle of the bottom of the concave die fixing plate 4, an upper die 6 is fixedly installed at the middle of the bottom of the concave die pad 5, a punch fixing plate 7 is fixedly installed at the middle of the top of the lower die base 1, a punch pad 8 is fixedly installed at the top of the punch fixing plate 7, and a lower die 9 is movably installed inside the punch pad 8;

[0031] A lifting structure 11 is fixedly installed inside the punch fixing plate 7, and the lifting structure 11 includes a fixed plate 1101 fixedly installed inside the punch fixing plate 7, a plurality of cylinders 1102 are installed on the top of the fixed plate 1101, the tops of the plurality of cylinders 1102 and the bottom of the lower mold 9 are fitted with each other, a guide groove 1104 is opened inside the lower mold 9, a plurality of exhaust holes 1105 are opened on the top of the lower mold 9, a bellows 1103 is installed between the bottom end of the lower mold 9 and the top end of the fixed plate 1101, T-shaped columns 1106 are equidistantly welded on the bottom end of the lower mold 9, the same fixing ring 1107 is sleeved on the outer side of the plurality of T-shaped columns 1106, and the fixing ring 1107 is fixedly installed inside the punch pad 8.

[0032] like Figure 3 and Figure 4As shown, a base 1108 is fixedly installed on the bottom edge of the fixing ring 1107, a positioning sleeve 1109 is fixedly installed on the top of the base 1108, a piston rod 1110 is movably connected up and down inside the positioning sleeve 1109, and the top of the piston rod 1110 is fixedly connected to the bottom of the lower mold 9, a limiting groove is provided on the outer surface of the piston rod 1110, a sealing gasket is clamped and installed at the outer side of the piston rod 1110 at the inner position of the limiting groove, and the sealing gasket and the inner edge of the positioning sleeve 1109 fit each other to increase the sealing between the piston rod 1110 and the positioning sleeve 1109, a hard tube 1111 is embedded and installed at the bottom of the outer surface of the positioning sleeve 1109, and the same guide ring 1112 is connected between the tops of several hard tubes 1111, and the outlet direction of the guide ring 1112 is located at the connection between the punch pad 8 and the lower mold 9;

[0033] As the lower die 9 moves, it drives the piston rod 1110 to move. When the piston rod 1110 moves, it squeezes the gas inside the positioning sleeve 1109, so that the positioning sleeve 1109 enters the guide ring 1112 along the hard tube 1111, and finally enters the connection between the punch pad 8 and the lower die 9 along the guide ring 1112, thereby blowing the connection between the punch pad 8 and the lower die 9, and allowing the gas to enter the outside of the lower die 9, thereby cleaning the outside of the lower die 9 and ensuring the cleanliness of the outside of the lower die 9.

[0034] like Figure 5 and Figure 6 As shown, a guide structure 10 is installed at the four corners of the bottom end of the die pad 5, and the guide structure 10 includes a pillar 1001 fixedly installed at the four corners of the bottom end of the die pad 5, a threaded sleeve 1002 is welded at the bottom end of the pillar 1001, a mounting ring 1003 is connected to the outer side of the threaded sleeve 1002 through a thread, a threaded sleeve 2 1004 is welded to the bottom end of the mounting ring 1003, a mounting ring 2 1005 is connected to the outer side of the threaded sleeve 2 1004 through a thread, and a wear-resistant head 1006 is fixedly installed at the bottom end of the mounting ring 2 1005, and the pillar 1001, the threaded sleeve 1002, the mounting ring 1003, the threaded sleeve 2 1004, the mounting ring 2 1005 and the wear-resistant head 1006 are combined to form a guide pillar.

[0035] The pillar 1001, the threaded sleeve 1002, the mounting ring 1003, the threaded sleeve 1004, the mounting ring 1005 and the wear-resistant head 1006 are installed in sequence, so that the pillar 1001, the threaded sleeve 1002, the mounting ring 1003, the threaded sleeve 1004, the mounting ring 1005 and the wear-resistant head 1006 are combined into a guide pillar, and the overall length of the combined guide pillar can be adjusted, so that the guide pillar can be used more reasonably.

[0036] like Figure 6 and Figure 7As shown, an extrusion spring 1007 is fixedly installed on the inner wall of the wear-resistant head 1006, a buffer block 1008 is fixedly installed on the top of the extrusion spring 1007, and the shape of the buffer block 1008 is T-shaped, and the buffer block 1008 runs through the wear-resistant head 1006. A circular hole is opened in the middle of the pillar 1001, the threaded sleeve 1002, the mounting ring 1003, the threaded sleeve 1004 and the mounting ring 1005. The inside of the mounting ring 1005 is located inside the circular hole and is slidably connected with a piston plate 1009. An air outlet is opened on the top of the pillar 1001, and lubricating oil is arranged inside the circular hole.

[0037] The piston plate 1009 is used to separate the mounting ring 2 1005 and the wear-resistant head 1006, and the piston plate 1009 can be pushed to move slowly under the action of gas pressure. When the piston plate 1009 moves slowly, it pushes the lubricating oil to be discharged along the inside of the circular hole, thereby lubricating the outside of the guide pillar.

[0038] like Figure 6 and Figure 7 As shown, a mounting cylinder 1010 is fixedly installed at the middle of the top of the wear-resistant head 1006, a guide hole 1011 is opened at the top of the outer surface of the wear-resistant head 1006, and a return spring 1012 is installed inside the guide hole 1011 and the mounting cylinder 1010, and a blocking plate 1013 is fixedly installed at one end of the return spring 1012;

[0039] When the buffer block 1008 moves downward, negative pressure is generated inside the wear-resistant head 1006. When negative pressure is generated in the wear-resistant head 1006, the gas adsorbs the blocking plate 1013 inside the mounting tube 1010, causing the blocking plate 1013 to move. When the blocking plate 1013 moves, it blocks the inside of the mounting tube 1010, and at the same time, the blocking plate 1013 inside the guide hole 1011 compresses the return spring 1012 due to the action of negative pressure, so that the guide hole 1011 opens, thereby allowing external gas to enter the inside of the wear-resistant head 1006. Conversely, the guide hole 1011 is closed and the inside of the mounting tube 1010 is opened, thereby allowing gas to enter the inside of the mounting ring 1005, thereby continuously pressurizing the inside of the mounting ring 1005, thereby changing the difficulty of continuously pressurizing the inside of the mounting ring 1005.

[0040] Working principle: During the actual use of the device, the lower die 9 moves to the highest point, and then the aluminum material is placed on the top of the lower die 9. At this time, the hydraulic rod 2 is started, and the hydraulic rod 2 drives the upper die seat 3 to move downward. When the upper die seat 3 moves, it drives the die fixing plate 4 to move. The die fixing plate 4 drives the upper die 6 to enter the material surface through the die pad 5, and stamps the material on the surface of the lower die 9. At this time, since the buffer block 1008 first fits with the top of the punch fixing plate 7 and moves upward, the buffer block 1008 drives the extrusion spring 1007 to stretch when it moves, and a positive pressure is formed inside the wear-resistant head 1006. At this time, the gas pushes the blocking plate 1013 inside the mounting tube 1010. When the blocking plate 1013 moves, it drives the reset spring 1012 to stretch, and at the same time, the gas pushes the blockage inside the guide hole 1011. Plate 1013, when the blocking plate 1013 moves, it drives the return spring 1012 to stretch, and makes the blocking plate 1013 block the inside of the guide hole 1011, so that the gas enters the inside of the mounting ring 1005, and pushes the piston plate 1009 inside the mounting ring 1005 to move. At this time, the piston plate 1009 pushes the lubricating oil to move upward, and the lubricating oil moving upward eventually drips outward along the outside of the pillar 1001, so that the lubricating oil enters the corresponding holes of the guide pillar and the punch pad 8, thereby reducing the friction between the moving parts, thereby reducing wear and extending the service life of the equipment, and at the same time can reduce the noise caused by friction during the stamping process, improve the comfort of the operating environment and production efficiency, and can also make the stamping process smoother, reduce jams and pauses, thereby improving production efficiency and product quality;

[0041] The pillar 1001, the threaded sleeve 1002, the mounting ring 1003, the threaded sleeve 1004, the mounting ring 1005 and the wear-resistant head 1006 are sequentially assembled into a guide pillar. At this time, the length of the guide pillar can be adjusted to meet the requirements of different installation environments and working conditions, thereby improving the flexibility and adaptability of installation, and the position and direction of the guide component can be adjusted more accurately to ensure that it can maintain good guiding performance during the working process. The corresponding components can also be easily replaced or adjusted without the need to replace the entire guide pillar as a whole, thereby reducing maintenance costs and time;

[0042] Finally, the upper mold 6 and the lower mold 9 are separated by starting, and then the cylinder 1102 is started. The cylinder 1102 drives the lower mold 9 to descend. At this time, the lower mold 9 is separated from the material, and at the same time, the gas inside the bellows 1103 enters the guide groove 1104, and enters the exhaust hole 1105 along the guide groove 1104, and finally enters the joint between the material and the lower mold 9 along the exhaust hole 1105, which changes the method of using a push pin to separate the material in the prior art. This method can effectively avoid scratches or other damage to the surface of the material, thereby reducing the deformation or damage that may occur to the material during the separation process, thereby improving the use efficiency of the material. Compared with the method of separating the material with a push pin, this method is softer, can reduce noise emissions during the production process, create a more comfortable working environment, and reduce direct impact on the mold, which helps to extend the service life of the mold;

[0043] Finally, when the lower mold 9 descends, the piston rod 1110 is driven to move. When the piston rod 1110 moves, the gas inside the positioning sleeve 1109 is squeezed, so that the positioning sleeve 1109 enters the guide ring 1112 along the hard tube 1111, and finally enters the connection between the punch pad 8 and the lower mold 9 along the guide ring 1112, thereby blowing the connection between the punch pad 8 and the lower mold 9, and allowing the gas to enter the outside of the lower mold 9, thereby cleaning the outside of the lower mold 9, ensuring the cleanliness of the outside of the lower mold 9. Since the outside of the lower mold 9 is cleaned in time, the influence of dirt and impurities in the processing process can be reduced, thereby improving the stability of the lower mold 9 when it descends, reducing wear, and extending the service life of the mold.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
