[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] like Figure 1 and Figure 2 As shown, a sealing gasket hot pressing molding demolding device includes: a base plate 20, which is a rectangular plate. This is existing technology and will not be described in detail here.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a suction-release structure is installed above the base plate 20 to demold the formed pad. The suction-release structure includes: an air box 21, an air pump 22, a connecting pipe 23, a support plate 30, a vent box 31, and an air outlet net 32. The air box 21 is fixedly connected to the top of the base plate 20. The air pump 22 is symmetrically fixedly connected to the top of the air box 21. The connecting pipe 23 is fixedly connected to the top of each air pump 22. The support plate 30 is fixedly connected to the top of the base plate 20. The vent box 31 is fixedly connected to the top of the support plate 30. The air outlet net 32 ​​is fixedly connected to the wall of the vent box 31. Another identical support plate 30 is also provided above the vent box 31. The wall of the other support plate 30 is also provided with the same air outlet net 32.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the air box 21 is a hollow rectangular box with an internal cavity. The cavity of the air box 21 can be connected to the symmetrical air pumps 22 at the top. The symmetrical connecting pipes 23 can be connected to the cavities of the two air boxes 31 respectively. The connecting pipes 23 are circular flexible tubes. The air boxes 31 are hollow boxes in the shape of right-angled triangles. The air outlet nets 32 on the walls of the symmetrical air boxes 31 face each other. The air boxes 31 have rectangular slots at the air outlet nets 32. The air outlet nets 32 are rectangular plates with multiple circular slots on their walls. The suction and detachment structure also includes a rear plate 33, a sliding frame 34, a connecting plate 35, and a screw 36. The rear plate 33 is fixedly connected to the top of the base plate 20. Located behind the support plate 30, the sliding frame 34 is slidably connected to the wall of the rear plate 33, the connecting plate 35 is fixedly connected to the top of the rear wall of the sliding frame 34, the screw 36 is threadedly connected to the wall of the connecting plate 35, the front wall of the sliding frame 34 can be fixedly connected to the rear wall of the upper vent box 31, the front wall of the rear plate 33 can contact the rear wall of the support plate 30, the rear plate 33 is a rectangular plate, the sliding frame 34 is a rectangular frame, the cavity of the sliding frame 34 can be adapted to the size of the rear plate 33, the screw 36 can pass through the bottom of the connecting plate 35 and be threadedly connected to the connecting plate 35, and the bottom end of the screw 36 can be rotatably connected to the top of the base plate 20.

[0030] In practical use, the power supply of air pump 22 is turned on. When the power supply of air pump 22 is turned on, air pump 22, which is connected to the lower air box 31, can blow the air in the air box 21 towards the lower air box 31. Another air pump 22 can draw air into the air box 21 through the upper air box 31 and the air outlet net 32. After turning on the power, place the required demolding pad and mold at the top air outlet net 32 ​​of the lower air box 31. Then, the bottom air outlet net 32 ​​of the upper air box 31 contacts the top of the pad. The round holes on the wall of the lower air outlet net 32 ​​can blow out air, while the upper air outlet net 32 ​​can absorb the pad to achieve demolding. When the screw 36 is rotated, the connecting plate 35 and the sliding frame 34 can move vertically along the wall of the rear plate 33, thereby driving the upper air box 31 to move horizontally.

[0031] In summary, by setting up symmetrical vent boxes 31, one of which can exhaust air and the other can draw air in, the gasket cooling can be accelerated while the gasket can be sucked out of the mold without deforming the gasket. Furthermore, the height-adjustable vent boxes 31 can be adapted to molds and gaskets of different sizes.

[0032] like Figure 5As shown, the bottom of the support plate 30 below has a bottom groove 40, and a cover plate 41 is rotatably connected inside the bottom groove 40. A connecting block 42 is fixedly connected to the bottom of the cover plate 41, and a bolt 43 is threadedly connected to the wall of the connecting block 42. The bottom groove 40 is a rectangular groove, and the cover plate 41 is a rectangular plate. The cover plate 41 can cover the bottom groove 40. The bottom of the vent box 31 at the bottom groove 40 has a threaded groove, and the bolt 43 can pass through the wall of the connecting block 42 and be threadedly connected to the connecting block 42. The bolt 43 can also enter the threaded groove on the wall of the vent box 31.

[0033] In actual use, when it is necessary to clean the vent box 31, the bolt 43 can be unscrewed from the wall of the connecting block 42 to unlock the position of the cover plate 41. At this time, the cover plate 41 can be flipped over to clean the impurities in the cavity of the vent box 31.

[0034] In summary, by setting the bottom groove 40 and the cover plate 41, it is easy to clean impurities when they enter the lower ventilation box 31 cavity, thereby preventing impurities from affecting the air outlet efficiency of the air outlet net 32.

[0035] Working principle: When the power of air pump 22 is turned on, air pump 22, which is connected to the lower air box 31, can blow the air in the air box 21 towards the lower air box 31. Meanwhile, another air pump 22 can draw air into the air box 21 through the upper air box 31 and the air outlet net 32. After turning on the power, place the required demolding pad and mold at the top air outlet net 32 ​​of the lower air box 31. Then, the bottom air outlet net 32 ​​of the upper air box 31 contacts the top of the pad. The round holes on the wall of the lower air outlet net 32 ​​can blow out air, while the upper air outlet net 32 ​​can absorb the pad to achieve demolding.
