Technical Field

[0001] The utility model relates to the field of rubber processing machinery, in particular to a rubber gasket hot pressing and forming device capable of automatically demolding. Background Art

[0002] A rubber gasket is a thin rubber product that seals between two static surfaces of a metal flange or other connection parts. It can be manufactured by molding or punched from vulcanized rubber sheets. It can be widely used in various mechanical equipment for functions such as lining, sealing, and buffering. Rubber gaskets have properties such as oil resistance, acid and alkali resistance, cold and heat resistance, and aging resistance. They can be directly cut into various shaped sealing gaskets and are widely used in industries such as medicine, electronics, chemical industry, antistatic, flame retardant, and food.

[0003] A patent with the patent announcement number CN213137522U discloses a rubber gasket hot pressing and forming machine, including a base. A lower mold is fixedly installed on the base, and a support column is arranged on the base. The upper end of the support column is fixedly installed with a fixed plate, and a hydraulic mechanism is fixedly installed on the fixed plate. An activity frame is arranged on the support column, and the activity frame is connected to the hydraulic mechanism. The lower surface of the activity frame is fixedly installed with an upper mold. A placement frame is arranged on the base, and a stacking structure for placing rubber parts is arranged on the base.

[0004] For the rubber gasket hot pressing and forming machine designed in the above patent, by hanging an air pipe nozzle through the placement frame, it aims to facilitate the operator to pick up and place the nozzle. However, this method requires the operator to frequently pick up and place the nozzle for taking the rubber gasket, which not only reduces the production efficiency but also increases the labor intensity of the operator. Therefore, to optimize this process, a rubber gasket hot pressing and forming device capable of automatically demolding is designed. By introducing an automated nozzle system, manual intervention is reduced, thereby improving the production efficiency and reducing the burden on the operator. Summary of the Utility Model

[0005] In order to overcome the drawback that the existing rubber gasket hot pressing and forming machine usually relies on manual discharging, resulting in low production efficiency, the purpose of the utility model is to provide a rubber gasket hot pressing and forming device capable of automatically demolding.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be described clearly and completely. 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 in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0020] Embodiment: A rubber gasket hot pressing and forming device capable of automatically demolding, as Figures 1-3As shown in the figure, it includes a machine base 1, a mounting frame 2, a hydraulic cylinder 3, a sliding rod 4, a fixing plate 5, a guide rod 6, a hot pressing plate 7, a template 71, a spring 8, an air pump 9, an outer frame 10, a connecting pipe 11 and a blowing nozzle 12. A mounting frame 2 is provided on the machine base 1. A hydraulic cylinder 3 is installed at the rear side of the top of the mounting frame 2. The fixing plate 5 is slidably installed on the inner top of the mounting frame 2 through two symmetric sliding rods 4. The piston rod of the hydraulic cylinder 3 penetrates into the mounting frame 2 and is connected to the fixing plate 5. The hot pressing plate 7 is slidably installed on the lower side of the fixing plate 5 through multiple guide rods 6. Springs 8 are sleeved on the guide rods 6 between the fixing plate 5 and the hot pressing plate 7. An air pump 9 is installed at the rear side of the top of the machine base 1. An outer frame 10 is provided at the front side of the top of the machine base 1. A template 71 is installed at the bottom of the outer frame 10. The air outlet of the air pump 9 is communicated with a connecting pipe 11. The blowing nozzle 12 is communicated with the inner wall of the outer frame 10. The connecting pipe 11 and the blowing nozzle 12 are communicated with each other; The template 71 is replaceably installed in the outer frame 10. Multiple uniformly distributed circular grooves are provided on the template 71. The hot pressing plate 7 presses down and fits on the template 71, so that the rubber gasket is pressed and formed in the circular grooves; The cross section of the outer frame 10 is slightly larger than the plate surface of the hot pressing plate 7. The front side of the outer frame 10 is a through port for air flow.

[0021] As Figure 1 and Figure 3 shown in the figure, it further includes a collection box 13 and a drawer 17. A collection box 13 is fixedly connected to the front side of the outer frame 10. The outer frame 10 is communicated with the collection box 13 through its through port. A drawer 17 is slidably installed inside the collection box 13. The drawer 17 is used to collect the pressed rubber gaskets blown out by the blowing nozzle 12; An air outlet pipe 131 is further provided on the collection box 13. The air outlet pipe 131 is communicated with the front side wall of the collection box 13. The air outlet pipe 131 can make the air flow blown out by the blowing nozzle 12 flow from the rear to the front inside the collection box 13, so as to drive the rubber gasket to be blown into the drawer 17 for collection.

[0022] As Figure 4 shown in the figure, it further includes a baffle 14, an electric push rod 15 and a connecting rod 16. A baffle 14 is slidably installed on the top of the outer frame 10. The baffle 14 is used to block the rubber gasket from flying outwards, avoiding the rubber gasket from flying out from the top of the outer frame 10. The baffle 14 can completely cover the top opening of the outer frame 10. Electric push rods 15 are symmetrically installed on the front side of the outer frame 10. The telescopic rods of the electric push rods 15 are connected to the baffle 14 through connecting rods 16.

[0023] When using this device, first activate the electric push rod 15, so that the electric push rod 15 drives the baffle 14 to move forward through the connecting rod 16, and the baffle 14 is moved out and opened from the opening at the top of the outer frame 10. The operator first puts the preparation raw materials of the rubber gasket into the pressing circular groove of the template 71, and then activates the hydraulic cylinder 3. The hydraulic cylinder 3 drives the fixed plate 5 to move downward through the piston rod. The fixed plate 5 will continuously move downward under the guidance of the sliding rod 4. The downward moving fixed plate 5 will also drive the hot pressing plate 7 to move downward synchronously. When the hot pressing plate 7 enters the outer frame 10 and presses against the template 71, the hydraulic cylinder 3 continues to drive the fixed plate 5 to press downward, so that the fixed plate 5 continuously presses the spring 8 under the guidance of the guide rod 6, and the spring 8 between the fixed plate 5 and the hot pressing plate 7 is continuously compressed until the hot pressing plate 7 is tightly pressed on the template 71 under the action of the spring 8. At this time, the hot pressing plate 7 is electrified and heated. The hot pressing plate 7 melts and presses the multiple preparation raw materials in the template 71 into the required rubber gasket. When the hot pressing plate 7 presses and cools the rubber gasket into shape, the hydraulic cylinder 3 reversely drives the fixed plate 5 and the hot pressing plate 7 to move upward and reset, and reversely drives the connecting rod 16 through the electric push rod 15, so that the connecting rod 16 drives the baffle 14 to move backward and cover back to the opening at the top of the outer frame 10. Then activate the air pump 9 and pump the gas into the connecting pipe 11. The pumped gas flows through the connecting pipe 11 and then enters the blowing nozzle 12. Finally, the high-speed air flow is blown from the blowing nozzle 12 onto the rubber gasket on the template 71, so that the pressed rubber gasket is blown from the template 71 into the drawer 17 of the collection box 13 for collection. Thus, it is realized that the rubber gasket can be automatically discharged and collected while being hot-pressed, improving the production efficiency of the rubber gasket.
