Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Please see Figure 1-4 This utility model provides a technical solution: A burr-free mold that is easy to assemble and disassemble includes a base plate 1, a control key 2 is provided at the middle of the right end of the base plate 1, a support back frame 3 is fixedly connected to the upper left end of the base plate 1, an upper mold drive device 4 is fixedly connected to the upper right end of the support back frame 3, a lower mold fixing seat structure 5 is fixedly connected to the upper left end of the base plate 1, and the lower part of the upper mold drive device 4 is located directly above the lower mold fixing seat structure 5.

[0026] In this embodiment, the upper mold driving device 4 includes a hydraulic cylinder 41. The output end of the hydraulic cylinder 41 passes through the upper left part of the support back frame 3 and is fixedly connected to a mounting plate 42. Fixing bolts 43 are threaded and movably connected to the upper perimeter of the mounting plate 42. T-shaped positioning slots 44 are formed at the front and rear of the upper end of the mounting plate 42. An upper mold component assembly 45 is disposed below the mounting plate 42. The upper mold component assembly 45 includes an upper mold base plate 451. Connecting plates 452 are fixedly connected to the upper perimeter of the upper mold base plate 451. The four connecting plates 452 are close to the upper mold base plate 451. One end is fixedly connected to a T-shaped positioning block 453. The upper end of each of the four connecting plates 452 has a through bolt hole 454. The lower middle part of the upper mold base plate 451 is fixedly connected to a stamping punch 455. The lower end of the stamping punch 455 is fixedly connected to a punch cutting edge 456. The upper mold base plate 451 is snapped into the mounting plate 42 through the four connecting plates 452. The two horizontally distributed T-shaped positioning blocks 453 are respectively inserted into the T-shaped positioning slots 44. The four connecting plates 452 are detachably connected to the mounting plate 42 through the four bolt holes 454 and the four fixing bolts 43.

[0027] The above solution provides driving force through a hydraulic cylinder 41, whose output end passes through the support back frame 3 and connects to the mounting plate 42, providing stable up-and-down movement for the upper mold assembly 45. The upper mold base plate 451 of the upper mold assembly 45 is connected to the T-shaped positioning slot 44 of the mounting plate 42 via the T-shaped positioning block 453 of the connecting plate 452, achieving precise positioning. Then, the fixing bolt 43 passes through the bolt hole 454 for fastening, ensuring a stable connection and convenient disassembly and assembly. The punch cutting edge 456 at the lower end of the stamping punch 455 matches the size of the stamping die 57 of the lower mold. This precise fit avoids the burr problem caused by the wear of the cutting edge and uneven gap in traditional molds. With the dual guarantee of T-shaped structure positioning and bolt fastening, the mold gap is uniform and worn parts can be quickly replaced, reducing subsequent grinding and polishing processes and effectively reducing costs and time.

[0028] In this embodiment, the lower mold fixing base structure 5 includes a lower mold base plate 51, which is fixedly connected to the upper end of the base plate 1. Fastening bolts 52 are threadedly connected to all four sides of the upper end of the lower mold base plate 51. A positioning groove 53 is formed in the middle of the upper end of the lower mold base plate 51. A lower mold clamping plate 54 is provided above the lower mold base plate 51. A positioning boss 55 is fixedly connected to the lower end of the lower mold clamping plate 54. Through bolt holes 58 are formed around all four sides of the upper end of the lower mold clamping plate 54. The middle of the upper end of the lower mold clamping plate 54 is fixed... A die holder 56 is connected, and a stamping die 57 is opened in the middle of the upper end of the die holder 56. The lower die clamping plate 54 is clamped to the lower die base plate 51 through the positioning boss 55 and the positioning groove 53. The lower die clamping plate 54 is detachably connected to the lower die base plate 51 through four bolt through holes 58 and four fastening bolts 52. The size of the stamping die 57 matches the size of the punch cutting edge 456. The die holder 56 is located directly below the stamping punch 455, and the area of ​​the die holder 56 is larger than the area of ​​the stamping punch 455.

[0029] With the above scheme: the lower die base plate 51 is fixed to the base plate 1, and the lower die clamping plate 54 is quickly clamped and positioned by the positioning boss 55 and the positioning groove 53. Then, the fastening bolt 52 is fastened through the bolt through hole 58. The positioning boss 55 and the positioning groove 53 are pre-fixed, and preliminary installation can be carried out without professional tools. The bolt through hole 58 only serves as a reinforcement. When disassembling, the fastening bolt 52 is loosened first and then the lower die clamping plate 54 is separated. The die pad 56 and the stamping die 57 are easy to replace individually due to the clamping structure. Moreover, the area is larger than that of the stamping punch 455, which not only ensures the stamping accuracy but also reduces the technical threshold of disassembly and assembly, and greatly shortens the working time.

[0030] It should be noted that this utility model is a burr-free mold that is easy to assemble and disassemble. During use, firstly, the device is started via control key 2. The hydraulic cylinder 41 of the upper mold drive device 4 drives the mounting plate 42 to move up and down, causing the upper mold assembly 45 to operate. The upper mold base plate 451 is inserted into the T-shaped positioning slot 44 of the mounting plate 42 via the T-shaped positioning block 453 of the connecting plate 452, and then reinforced by fixing bolts 43 passing through bolt holes 454, so that the stamping punch 455 and punch cutting edge 456 move down precisely. In the lower mold fixing base structure 5... The lower die clamping plate 54 is clamped to the positioning groove 53 of the lower die base plate 51 through the positioning boss 55, and the fastening bolt 52 is fixed through the bolt through hole 58. The stamping die 57 of the die pad plate 56 and the punch cutting edge 456 are precisely matched to complete the stamping. During operation, the T-shaped structure ensures accurate positioning and avoids burrs caused by uneven gaps. During disassembly and assembly, the clamping parts can be separated by loosening the fastening bolt 52 without complicated tools. Therefore, this mold achieves precise burr-free stamping and greatly simplifies the disassembly and assembly process, reduces reliance on professional personnel, and saves time and costs.
