[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model 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.

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: a hot pressing mold for a valve rubber seat, including an operating table 1 and a demolding mechanism 5. A lower mold 2 is installed on one side of the surface of the operating table 1, an upper mold 3 is installed on one side of the surface of the operating table 1, a cooling mechanism 4 is arranged on one side of the surface of the operating table 1, and a demolding mechanism 5 is arranged inside the lower mold 2;

[0021] The demolding mechanism 5 includes a mounting groove 501, a movable groove 502, a support plate 503, a handle 504, a connecting plate 505, a sleeve 506, a sliding rod 507, a return spring 508, a connecting rod 509 and a top plate 510. A mounting groove 501 is opened inside the lower mold 2, a movable groove 502 is opened inside the lower mold 2, a support plate 503 is installed inside the mounting groove 501, a handle 504 is installed on one side of the surface of the support plate 503, a connecting plate 505 is fixedly connected to one side of the surface of the support plate 503, a sleeve 506 is fixedly connected to one side of the surface of the support plate 503, a sliding rod 507 is fitted inside the sleeve 506, a return spring 508 is sleeved on the surface of the sleeve 506, a connecting rod 509 is fixedly connected to one side of the surface of the connecting plate 505, and the other end of the connecting rod 509 is fixedly connected to a top plate 510. Through the settings of the mounting groove 501, the movable groove 502, the support plate 503, the handle 504, the connecting plate 505, the sleeve 506, the sliding rod 507, the return spring 508, the connecting rod 509 and the top plate 510, when in use, after the workpiece is formed, the handle 504 can be pulled. At this time, the handle 504 drives the support plate 503 to lift upward, the sliding rod 507 slides relative to the sleeve 506, and at the same time the return spring 508 is compressed and deformed. The support plate 503 drives the connecting plate 505 to lift upward. At this time, the connecting plate 505 drives the top plate 510 to lift through the connecting rod 509, so that the top plate 510 pushes the workpiece out of the inside of the lower mold 2. Release the force applied to the handle 504, and the return spring 508 rebounds and deforms to drive the support plate 503 to return to its original position, thereby driving the top plate 510 to return to its original position.

[0022] Furthermore, both ends of the support plate 503 extend out of the inside of the mounting groove 501, and two groups of handles 504 are provided. Through the setting of the handle 504, the handle 504 can drive the support plate 503 to move.

[0023] Furthermore, the connecting plate 505 is symmetrically distributed, the slide rod 507 and the sleeve 506 constitute a mutually sliding structure, one end of the slide rod 507 is fixedly connected to the lower mold 2, and through the arrangement of the sleeve 506 and the slide rod 507, when in use, the sleeve 506 and the slide rod 507 slide against each other to limit the reset spring 508 without affecting the deformation of the reset spring 508.

[0024] Furthermore, one end of the return spring 508 is fixedly connected to the support plate 503, and the other end of the return spring 508 is fixedly connected to the lower mold 2. Through the setting of the return spring 508, when in use, the return spring 508 can rebound and deform when the handle 504 loses its force, driving the support plate 503 to return to its original position.

[0025] Furthermore, the connecting rod 509 is embedded in the movable groove 502. The connecting rod 509 is an "L"-shaped rod. Through the setting of the connecting rod 509, when in use, one end of the connecting rod 509 is connected to the connecting plate 505, and the other end is connected to the top plate 510, so that the connecting rod 509 drives the top plate 510 to move when the connecting plate 505 moves.

[0026] Furthermore, the cooling mechanism 4 includes a support frame 401, a fixing buckle 402, a ventilation pipe 403, an air outlet nozzle 404 and a fan 405. The support frame 401 is installed on one side of the surface of the operating table 1, and the fixing buckle 402 is fixedly connected to one side of the surface of the support frame 401. The interior of the fixing buckle 402 is penetrated by a ventilation pipe 403, and one side of the surface of the ventilation pipe 403 is sealed with an air outlet nozzle 404. One end of the ventilation pipe 403 is connected to the fan 405. Through the arrangement of the support frame 401, the fixing buckle 402, the ventilation pipe 403, the air outlet nozzle 404 and the fan 405, when the upper mold 3 is lifted, the fan 405 is turned on. At this time, the fan 405 conveys wind to the air outlet nozzle 404 through the ventilation pipe 403. Since the air outlet nozzle 404 is inclined toward the lower mold 2, the air outlet nozzle 404 blows air to cool the workpiece inside the lower mold 2.

[0027] Furthermore, the air outlet nozzles 404 are inclined toward the lower mold 2, and are distributed at equal intervals. The fan 405 is installed on the surface of the operating table 1. Through the setting of the air outlet nozzles 404, when in use, the air outlet nozzles 404 can blow air to cool the workpiece inside the lower mold 2.

[0028] Working principle: After the upper mold 3 is lifted, the blower 405 is turned on. At this time, the blower 405 conveys air to the air outlet nozzle 404 through the ventilation pipe 403. Since the air outlet nozzle 404 is inclined downward with respect to the lower mold 2, the air outlet nozzle 404 blows air to cool the workpiece inside the lower mold 2. When the workpiece is formed, the handle 504 can be pulled. At this time, the handle 504 drives the support plate 503 to lift upward. The slide rod 507 and the sleeve 506 slide relative to each other. At the same time, the return spring 508 is compressed and deformed. The support plate 503 drives the connecting plate 505 to lift upward. At this time, the connecting plate 505 drives the top plate 510 to lift through the connecting rod 509. Thus, the top plate 510 ejects the workpiece out of the inside of the lower mold 2. Release the force applied to the handle 504, and the return spring 508 rebounds and deforms to drive the support plate 503 to return to its original position, thereby driving the top plate 510 to return to its original position.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
