[0032] 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 making creative efforts belong to the protection scope of the present utility model.

[0033] Please refer to Figures 1-4 ,

[0034] First embodiment:

[0035] The present utility model provides a technical solution: a high-temperature valve body mold, including a bottom plate 1, a fixed block 2 and a connecting block 3 are connected to the bottom plate 1, a hydraulic component 4 is connected to the fixed block 2, a fixed plate 8 is installed on the connecting block 3, a first mold 5 is installed on one side of the hydraulic component 4, a second mold 6 is installed on one side of the fixed plate 8, and the same limiting component 7 for limiting the movement trajectories of the first mold 5 and the second mold 6 is connected outside the hydraulic component 4 and the fixed plate 8. By setting the limiting component 7, the limiting component 7 limits the first mold 5 and the second mold 6 to prevent the first mold 5 and the second mold 6 from shaking when moving; a monitoring component 9 for monitoring the contact pressure between the first mold 5 and the second mold 6 is connected to the front surfaces of the first mold 5 and the second mold 6; fixing components 10 are installed on the upper and lower surfaces of the first mold 5 and the second mold 6;

[0036] The fixing component 10 includes two vertical plates 101 and two horizontal plates 106. Nuts 102 and threaded rods 103 are provided on the vertical plates 101, and locking rods 107 are provided on the horizontal plates 106.

[0037] Specifically, as Figures 2-3As shown, the hydraulic component 4 includes a hydraulic cylinder 41 and a locking plate 42. The hydraulic cylinder 41 is connected to the fixed block 2. A fixing hole 43 is provided in the locking plate 42, and the hydraulic cylinder 41 is connected within the fixing hole 43. By providing the hydraulic cylinder 41 and the fixing hole 43, the fixing hole 43 can limit the hydraulic cylinder 41 to prevent the hydraulic cylinder 41 from shaking during operation; the output end of the hydraulic cylinder 41 is connected to a push plate 44, and one side of the push plate 44 is connected to a mounting plate 45. The first mold 5 is mounted on one side of the mounting plate 45. The limiting component 7 includes four limiting plates 71, and the four limiting plates 71 are respectively connected to the upper surface and the lower surface of the locking plate 42 and the fixing plate 8. Two sliding rods 72 are slidably connected within the two upper limiting plates 71 and the two lower limiting plates 71. By providing the limiting plates 71 and the sliding rods 72, the limiting plates 71 limit the sliding rods 72 to prevent the sliding rods 72 from shaking during sliding; two adjacent sliding rods 72 are sleeved with collar rings 73, and the two collar rings 73 are respectively connected to the upper surface and the lower surface of the mounting plate 45. Sealing gaskets are provided at the edges of the adjacent surfaces of the first mold 5 and the second mold 6. By providing the sealing gaskets, the sealing gaskets can prevent leakage between the first mold 5 and the second mold 6; locking blocks with a diameter slightly larger than the end face diameter of the sliding rods 72 are provided at both ends of the sliding rods 72 for limiting the sliding rods 72 within the limiting plates 71. The inner diameter of the collar ring 73 is slightly larger than the end face diameter of the sliding rods 72, and the two are in close fit. The monitoring component 9 includes a control panel 91, a pressure rod 92, and a pressure sensor 94. By providing the pressure sensor 94, the degree of fit between the first mold 5 and the second mold 6 can be monitored; the control panel 91 is mounted on the bottom plate 1, the pressure rod 92 is connected to the front of the first mold 5, a sphere 93 is connected to one side of the pressure rod 92, the pressure sensor 94 is connected to the front of the second mold 6, and the pressure sensor 94 corresponds to the position of the sphere 93. The control panel 91 is electrically connected to the pressure sensor 94.

[0038] During operation, by starting the hydraulic cylinder 41, the hydraulic cylinder 41 drives the push plate 44 to move in a specified direction. The movement of the push plate 44 causes it to slide smoothly along the sliding track outside the sliding rods 72 through the collar rings 73, and at the same time, it pushes the mounting plate 45 and the first mold 5 connected to the push plate 44 to move together. When the first mold 5 gradually approaches and finally contacts the fixed second mold 6, the hydraulic cylinder 41 continues to apply power to push the first mold 5 and the second mold 6 to fit tightly. During this process, the first mold 5 further drives the pressure rod 92 and the connected sphere 93 to move forward, applying a thrust to the pressure sensor 94 installed in the device. When the pressure value detected by the pressure sensor 94 reaches the predetermined requirement, the operation of the hydraulic cylinder 41 will automatically stop, ensuring that the fixing and joining between the molds reach the required standard, thereby achieving a firm connection between the first mold 5 and the second mold 6 during casting, so that the two will not be displaced or shaken.

[0039] Second Embodiment:

[0040] Specifically, as Figure 4 shown, two vertical plates 101 are respectively connected to a limiting plate 71 and a mounting plate 45. A handle 104 is connected to the threaded rod 103. A second positioning sleeve 105 is clamped under the threaded rod 103. By setting the second positioning sleeve 105 and the threaded rod 103, the second positioning sleeve 105 can limit the threaded rod 103 to prevent it from shaking or disengaging when being clamped inside. Two second positioning sleeves 105 are respectively connected to the first mold 5 and the second mold 6. Two horizontal plates 106 are respectively connected under a limiting plate 71 and a mounting plate 45. A first positioning sleeve 108 is clamped at one end of the locking rod 107. Two first positioning sleeves 108 are respectively connected under the first mold 5 and the second mold 6.

[0041] When replacing different molds, only need to rotate the handle 104 at this time. The handle 104 drives the threaded rod 103 to move away from the second positioning sleeve 105. Then the new mold can be replaced. Subsequently, the first positioning sleeve 108 at the bottom of the new mold is clamped into the locking rod 107. Then rotate the handle 104 to drive the threaded rod 103 to be clamped into the second positioning sleeve 105 of the new mold, thus realizing the replacement of the mold and avoiding the problem of troublesome replacement when using multiple bolts for fixation.

[0042] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacement or change, and should be covered within the protection scope of the present utility model.
