Description

Technical Field

[0001] The utility model relates to the technical field of sealing gasket processing, in particular to a sealing gasket hot pressing molding device. Background Art

[0002] A sealing gasket is a device used to fill the gap between two relatively moving mechanical parts to prevent liquid or gas leakage. It is usually made of soft materials such as rubber, polytetrafluoroethylene, etc. Sealing gaskets are widely used in mechanical equipment, automobile engines, pipeline systems and other fields. Sealing gaskets are usually processed by hot pressing forming devices, mainly to ensure that the sealing gaskets have good sealing performance and dimensional accuracy. Hot pressing forming is a processing method that places hot-processed materials in a mold and applies pressure to deform them. For sealing gaskets, hot pressing can ensure that the material reaches the desired shape and density under high temperature and high pressure, thereby improving its sealing performance and durability.

[0003] At present, the existing device (such as patent number: CN220030937U) discloses a hot press forming device, which is based on the upper mold assembly and the lower mold assembly assembled and arranged in cooperation with the limit seat, so that the product forming cavity with the same size is constructed each time the hot press forming is performed, thereby ensuring the consistency of the hot press forming of the product; and the first sealing ring forming part, the second sealing ring forming part, the first positioning hole forming part and the second positioning hole forming part are combined to achieve one-time hot press forming of a large number of sealing rings and positioning holes for the sheet to be hot pressed, and the hot press forming effect and efficiency are high;

[0004] However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: when the device is hot-pressed, the material needs to be placed in the groove of the lower mold for hot pressing. Due to different process requirements, the material of some sealing gaskets has a high viscosity (such as vulcanized rubber, etc.). After hot pressing, the material is easy to adhere to the inner wall of the lower mold, which is not convenient for the staff to remove. The applicability needs to be improved. Utility Model Content

[0024] The embodiment of the present application provides a sealing gasket hot pressing forming device, which effectively solves the technical problem of insufficient practicality of the existing device. By turning on the motor, the motor drives the screw rod to rotate and transmit threaded transmission to the support plate, so that the support plate drives the top column and the step column to slide upward into the second through groove and the first through groove as a whole. Since the sealing gasket is sleeved on the step column at this time, the movement of the step column will bring the sealing gasket out as a whole, thereby facilitating the removal of the sealing gasket in the ring and avoiding the difficulty in removing the sealing gasket due to material adhesion in the ring, thereby increasing practicality. When the motor is turned on, the motor drives the screw rod to rotate and transmit threaded transmission to the support plate, so that the support plate drives the slider to slide in the slide groove, thereby providing additional limit and increasing stability. By turning on the motor, the position of the top column and the step column in the first through groove can also be controlled. It can also be suitable for sealing gaskets of different thicknesses, thereby improving applicability.

[0025] like Figure 1-Figure 4 As shown, the technical solution in the embodiment of the present application is to effectively solve the technical problem that the existing device is not practical enough. The overall idea is as follows:

[0026] In view of the problems existing in the prior art, the utility model provides a sealing gasket hot pressing forming device, comprising a support column 11 and a workbench 12, each support column 11 is located at the four corners of the workbench 12, the workbench 12 and the support column 11 are fixedly installed, a hot pressing forming unit 13 is provided at the upper end of the workbench 12, an upper mold 14 is provided at the lower end of the hot pressing forming unit 13, a lower mold 15 is provided at the upper end of the workbench 12, the lower mold 15 is located inside the hot pressing forming unit 13, the lower mold 15 is adapted to the upper mold 14, and a fixing plate 16 is fixedly installed inside each support column 11;

[0027] A material taking mechanism is fixedly mounted on the upper end of the fixed plate 16;

[0028] The material-grabbing mechanism includes a motor 17, on the output shaft of which a screw rod 18 is fixedly mounted, and the screw rod 18 is rotatably mounted with the workbench 12. A slide groove 19 is provided inside each support column 11. The material-grabbing mechanism also includes a slider 21, a support plate 22, a first through groove 23, a second through groove 24, a top column 25 and a step column 26. By turning on the motor 17, the motor 17 drives the screw rod 18 to rotate and to transmit threaded transmission with the support plate 22, so that the support plate 22 drives the top column 25 and the step column 26 to slide upward into the second through groove 24 and the first through groove 23 as a whole and to be ejected. Since the sealing gasket is now sleeved on the step column 26, the movement of the step column 26 will bring out the sealing gasket as a whole, thereby facilitating the removal of the sealing gasket in the ring, avoiding the difficulty in removing the sealing gasket due to the adhesion of the material in the ring, and increasing practicality.

[0029] Each slider 21 is located inside the slide groove 19, and each slider 21 is slidably installed with the slide groove 19. The support plate 22 is located on the circumferential surface of the screw rod 18, and the support plate 22 is threadedly installed with the screw rod 18. The support plate 22 is fixedly installed with the slider 21. Each first through groove 23 is opened through the lower mold 15, and each second through groove 24 is opened through the workbench 12. Each first through groove 23 is connected with the second through groove 24. Each top column 25 is located at the upper end of the support plate 22, and each top column 25 is fixedly installed with the support plate 22. Each top column 25 is slidably installed with the second through groove 24. Each step column 26 is located at the upper end of the top column 25, each step column 26 is fixedly installed with the top column 25, and each step column 26 is slidably installed with the first through groove 23. When the motor 17 is turned on, the motor 17 drives the screw rod 18 to rotate and transmits threaded transmission with the support plate 22, so that the support plate 22 drives the slider 21 to slide in the slide groove 19, thereby providing additional limit and increasing stability. By turning on the motor 17, the top column 25 and the step column 26 can also be controlled to be located in the position of the first through groove 23, and it can also be suitable for sealing gaskets of different thicknesses to improve applicability.

[0030] Working principle:

[0031] In the first step, when the sealing gasket strip needs to be processed, the sealing gasket strips can be inserted into the annular portion between the step column 26 and the first through groove 23 one by one. When the placement is completed, the hot pressing molding unit 13 can be turned on, so that the hot pressing molding unit 13 drives the upper mold 14 to hot press the annular portion between the step column 26 and the first through groove 23, so that the sealing gasket strip is hot pressed into an integral annular sealing gasket, and then the hot pressing molding unit 13 can be reset;

[0032] In the second step, the staff can then turn on the motor 17, so that the motor 17 drives the screw rod 18 to rotate and transmit threaded transmission with the support plate 22, so that the support plate 22 drives the slider 21 to slide in the slide groove 19 and slide the top column 25 and the step column 26 as a whole into the second through groove 24 and the first through groove 23 and push them upward. Since the sealing gasket is now sleeved on the step column 26, the movement of the step column 26 will bring the sealing gasket out as a whole. Then the staff can take the sealing gasket at the step column 26, and then reset the motor 17 and continue the production of the sealing gasket. In addition, by turning on the motor 17 before processing, the top column 25 and the step column 26 can be controlled to be located in the first through groove 23, so it can be suitable for sealing gaskets of different thicknesses.

[0033] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
