[0002] A valve plate is a working resistor piece with non-linear volt-ampere characteristics and is mainly used in valve type lightning arresters. It plays a role in sealing and regulating by controlling the flow of fluid. Specifically, the valve plate is composed of a valve body, a sealing ring, etc. When the valve plate is closed, the sealing ring plays a sealing role to prevent fluid from passing through the valve. In addition, the valve plate is also applied to shock absorbers. As a shock absorber regulating valve, its core duty is to control the signal output by the control unit to realize the regulation of control elements such as flow rate, pressure, temperature, and liquid level through power operation. In short, the valve plate is a key component that plays a regulating role.

Specific implementation mode
[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] Embodiment 1
[0022] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: a forming mold for valve plate production, including: a workbench 1, a power-providing air cylinder 2 fixedly connected to the top of the workbench 1, an upper die replacement mechanism 4 capable of placing the mold is arranged at the top of the air cylinder 2, a disassembly and assembly mechanism 5 for facilitating the disassembly and assembly of the mold is arranged inside the upper die replacement mechanism 4, and a buffer protection mechanism 3 capable of providing buffer protection is arranged between the workbench 1 and the upper die replacement mechanism 4. When in use, by setting the air cylinder 2, the position of the upper die replacement mechanism 4 can be controlled to rise and fall, thereby facilitating the valve plate mold forming work. By setting the upper die replacement mechanism 4, it is convenient to place and replace the upper die 43. By setting the disassembly and assembly mechanism 5, when different types of valve plates need to be produced, the required forming mold can be replaced, which not only reduces the manufacturing cost but also meets the requirements of valve plate production. By setting the buffer protection mechanism 3, when the upper die replacement mechanism 4 moves downward for forming work, it can provide a buffer and shock-absorbing effect, preventing excessive impact force during forming from generating vibration, thereby helping the mold forming work.
[0023] The buffer protection mechanism 3 includes a fixed column 31 fixedly connected to the top of the workbench 1. A circular groove 32 is formed inside the fixed column 31. A sliding disk 33 is slidably connected to the inner wall of the circular groove 32. A connecting column 34 is fixedly connected to the top of the sliding disk 33. A shock-absorbing gasket 37 is fixedly connected to the outside of the connecting column 34 and above the fixed column 31. A fixed ring plate 35 is slidably connected to the outside of the connecting column 34 between the fixed column 31 and the shock-absorbing gasket 37. A first spring 36 is fixedly connected between the fixed ring plate 35 and the fixed column 31 and outside the connecting column 34. During use, when the upper die replacement mechanism 4 moves downward, it will drive the connecting column 34 fixedly connected to the bottom to move downward, causing the downward-moving connecting column 34 to drive the sliding disk 33 to slide downward in the circular groove 32. When the shock-absorbing gasket 37 on the outside of the connecting column 34 driven by the upper die replacement mechanism 4 contacts the fixed ring plate 35, it will be squeezed, thereby driving the fixed ring plate 35 to compress the first spring 36, and shock absorption and buffer protection are realized through the shock-absorbing gasket 37 and the first spring 36.
[0024] The upper die replacement mechanism 4 includes a top plate 41 fixedly connected to the output end of the cylinder 2. A mounting seat 42 is fixedly connected to the bottom of the top plate 41. An upper die 43 is arranged at the bottom of the mounting seat 42. A limiting plate 44 is fixedly connected to the outside of the upper die 43. During use, by placing the upper die 43 in the mounting seat 42, when the top plate 41 is driven to move downward, it will drive the upper die 43 at the bottom to perform die forming work, and limiting protection can be provided through the limiting plate 44.
[0025] The disassembly and assembly mechanism 5 includes a first chute 51 formed inside the mounting base 42. A first slider 52 is slidably connected to the inner wall of the first chute 51. One side of the first slider 52 is fixedly connected to a connecting rod 592. The end of the connecting rod 592 away from the first slider 52 is fixedly connected to a connecting handle 54. A second spring 53 is sleeved on the outer side of the connecting rod 592 and on one side of the first slider 52. A bolt 55 is threadedly connected inside the connecting handle 54, and the bolt 55 is threadedly connected to the mounting base 42. One side of the connecting handle 54 is fixedly connected to a positioning angle block 56. A rotating pull plate 57 is rotatably connected inside the positioning angle block 56. A second chute 58 is formed inside the upper die 43. An inverted hook plate 59 is slidably connected to the inner wall of the second chute 58. A limiting and reinforcing rod 591 is fixedly connected to the inner wall of the second chute 58. A third spring 590 is sleeved on the outer side of the limiting and reinforcing rod 591 and above the inverted hook plate 59. During use, when the upper die 43 needs to be replaced, the bolt 55 is rotated and removed. Then, the inverted hook plate 59 is pulled to move upward along the inner wall of the second chute 58 and the outer side of the limiting and reinforcing rod 591 to compress the third spring 590. Then, the rotating pull plate 57 is toggled to flip and removed from the inverted hook plate 59. Thus, the compressed third spring 590 drives the inverted hook plate 59 to reset. After that, the connecting handle 54 is pulled to drive the positioning angle block 56 away from the upper die 43, and the first slider 52 is driven by the connecting rod 592 to slide in the first chute 51, so that the driven first slider 52 compresses the second spring 53. Thus, when the positioning angle block 56 no longer limits the upper die 43, it can be replaced. Then, conversely, the above disassembly operation can be performed to replace the new upper die 43.
[0026] Embodiment 2
[0027] As Figures 1 to 3 , in the second embodiment, other structures remain unchanged. Different from the first embodiment, grooves are provided on both sides of the connecting handle 54, which can be used to pull the connecting handle 54, thereby providing a gripping position for the staff. A lower die 7 is provided on the top of the workbench 1, which is convenient for mold forming work. A control panel 6 is fixedly connected to one side of the workbench 1, and the control panel 6 is electrically connected to the cylinder 2, which is convenient for controlling the overall operation of the device, thereby providing convenience for the staff to control and operate the device.
