[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. Example

[0025] In one embodiment, Figure 1-Figure 5 As shown, a rubber mold with an auxiliary demoulding structure comprises a lower mold 11, wherein the lower mold 11 is fixedly arranged on the upper end of a first mounting plate 13, an upper mold 14 is closely arranged on the upper end of the lower mold 11, a plurality of positioning rods are fixedly arranged on the upper end of the lower mold 11, and positioning holes are arranged at the upper end of the upper mold 14 and at positions corresponding to the positioning rods, a molding chamber 12 is arranged inside the lower mold 11, a push plate 33 is slidably arranged inside the molding chamber 12, a pushing mechanism is arranged at the bottom end of the lower mold 11 for pushing the push plate 33 to move so that the lower mold 11 can be demoulded quickly, the interior of the lower mold 11 is hollow, a connecting pipe 15 is connected to the bottom end of the lower mold 11, and a heat dissipation mechanism is arranged at one end of the connecting pipe 15 for quickly cooling the molding chamber 12, the pushing mechanism facilitates the sliding of the push plate 33, so that the product inside the molding chamber 12 is pushed out, thereby facilitating rapid demoulding, and the heat dissipation mechanism facilitates cooling the inside of the molding chamber 12, so as to speed up production efficiency;

[0026] The pushing mechanism includes two symmetrically arranged transfer tubes 16, both of which are fixedly arranged inside the lower mold 11, and a piston plate is slidably arranged inside the transfer tube 16, and a push rod 22 is fixedly arranged on the upper end of the piston plate, and one end of the push rod 22 is fixedly connected to the bottom end of the push plate 33, and a first return spring 23 is fixedly arranged between the upper end of the piston plate and the upper end of the transfer tube 16, and the bottom end of the transfer tube 16 is connected with a first transmission pipe, and the other end of the first transmission pipe is connected with the output end of the water pump 17, and the water pump 17 is fixedly arranged on the upper end of the second mounting plate 18, and the second mounting plate 18 is fixedly arranged on several supporting legs at the bottom end of the first mounting plate 13, and the input end of the water pump 17 is connected with a second transmission pipe, and the second transmission pipe is connected with the output end of the water pump 17. One end is connected to the inside of the water tank 19 at the upper end of the third mounting plate 20, and the third mounting plate 20 is fixed on a plurality of supporting legs. When in use, when it is necessary to demold the product inside the molding chamber 12, the upper mold 14 is removed, and then the water pump 17 is started. The input end of the water pump 17 draws liquid from the inside of the water tank 19, and then the water pump 17 transports the liquid to the inside of the transfer tube 16. As the water pump 17 continues to transport, the hydraulic pressure inside the transfer tube 16 increases, so that the liquid pushes the piston plate to slide inside the transfer tube 16, and the piston plate pushes the push plate 33 to slide inside the molding chamber 12 through the push rod 22, so that the product inside the molding chamber 12 is pushed out, thereby facilitating demolding. The transfer tube 16 is provided with a drainage component for discharging the liquid inside the transfer tube 16.

[0027] The liquid discharge assembly includes a third transmission pipe, and the transfer pipe 16 is connected to a third transmission pipe, and the other end of the third transmission pipe is connected to the input end of the valve 34, and the output end of the valve 34 is connected to one end of the second return pipe 32, and the other end of the second return pipe 32 is connected to the inside of the water storage tank 19. During use, when it is necessary to return the push plate 33 to the initial position, the valve 34 is opened to allow the liquid inside the transfer pipe 16 to be discharged into the water storage tank 19 through the third transmission pipe and the second return pipe 32, thereby discharging the liquid inside the transfer pipe 16 and facilitating the transfer pipe 16 to return to its initial position.

[0028] The heat dissipation mechanism includes two symmetrically arranged connecting pipes, one end of each of the connecting pipes is connected to one end of the connecting pipe 15, and the two connecting pipes are respectively connected to one end of two transfer pipes 16. The lower mold 11 is respectively connected to one end of two first return pipes 21, and the other ends of the two first return pipes 21 are connected to the inside of the water storage tank 19. A plurality of refrigerators 36 are fixedly arranged on the water storage tank 19, and a plurality of overflow weirs 35 are fixedly arranged inside the water storage tank 19. When it is necessary to dissipate heat and cool the inside of the molding chamber 12, the water pump 17 is started, and the water pump 17 is transported to the inside of the transfer pipe 16 through the first transmission pipe. Refrigerant, since the upper mold 14 is tightly attached to the upper end of the lower mold 11, the piston plate does not move, and then the refrigerant enters the lower mold 11 through the connecting pipe and the connecting pipe 15. When the lower mold 11 is filled with refrigerant, the refrigerant flows back into the water tank 19 through the first return pipe 21, so that the refrigerant circulates and takes away the heat inside the molding chamber 12 during the flow, thereby facilitating rapid cooling of the product. At the same time, the refrigerator 36 can cool the refrigerant in the water tank 19, and the overflow weir 35 can increase the cooling time of the refrigerant. The connecting pipe is provided with a switching component for switching the flow direction of the refrigerant.

[0029] The switching assembly includes a stopper 24, which is slidably arranged inside the first fixed tube, and the first fixed tube is connected to the connecting tube. A second return spring 25 is fixedly arranged between the bottom end of the stopper 24 and the bottom end of the first fixed tube. The bottom end of the stopper 24 is connected to one end of a connecting frame 26, and the other end of the connecting frame 26 is fixedly arranged on a sliding plate 27. The sliding plate 27 is slidably arranged in a rectangular perforation at the upper end of the first mounting plate 13. A support plate is fixedly arranged on one side of the sliding plate 27, and a third return spring 28 is fixedly arranged between the upper end of the support plate and the bottom end of the first mounting plate 13. Connecting plates are fixedly arranged at the positions corresponding to one end of the sliding plate 27 on both sides of the upper mold 14. When in use, when it is necessary to inject a product, the upper mold 14 is placed close to the upper end of the lower mold 11, and then to the molding chamber. 12, the upper mold 14 is tightly attached to the upper end of the lower mold 11, and the connecting plate pushes the sliding plate 27 to slide under the action of the upper mold 14's own gravity, and the sliding plate 27 drives the connecting frame 26 to slide. The connecting frame 26 moves and pulls the stopper 24 to slide, so that the stopper 24 slides to the inside of the first fixed tube. When cooling is required, the refrigerant enters the connecting tube 15 through the connecting tube. When demoulding is required, the upper mold 14 is separated from the upper end of the lower mold 11, and then under the action of the third return spring 28, the sliding plate 27 returns to the initial position, and the sliding plate 27 drives the stopper 24 to return to the initial position through the transfer tube 16, so that the stopper 24 blocks the connecting tube, so that when the water pump 17 transports the refrigerant to the inside of the transfer tube 16, the refrigerant can push the piston plate to move.

[0030] The cooling surface of the refrigerator 36 is fixed with a plurality of fins 37 , and the plurality of fins 37 are arranged at equal intervals, so as to enhance the cooling effect of the refrigerant in the water storage tank 19 when in use. Example

[0031] The difference from Example 1 is that a limit frame is fixedly provided at the bottom end of the piston plate, a push rod 30 is slidably provided on the inner side of the limit frame, a second fixed tube is slidably provided on the push rod 30, and the second fixed tube is fixedly provided on the transfer tube 16, one end of the push rod 30 is tightly arranged with the inclined surface of the guide block 29, the guide block 29 is fixedly provided on one side of the sliding plate 27, a circular fixed plate is fixedly provided on the push rod 30, and a tension spring 31 is fixedly provided between one side of the circular fixed plate and one side inside the second fixed tube. When in use, when the sliding plate 27 moves, the sliding plate 27 drives the guide block 29 to move, and the inclined surface of the guide block 29 guides the push rod 30, so that one end of the push rod 30 is inserted into the inner side of the limit frame, thereby fixing the piston plate, so as to prevent the coolant from pushing the piston plate to move when the heat is dissipated inside the molding chamber 12, so that the push plate 33 pushes the product inside the molding chamber 12, thereby causing product damage.

[0032] One end of the push rod 30 is provided with a ball, which is convenient for reducing the wear between one end of the push rod 30 and the inclined surface of the guide block 29 when in use.

[0033] The above embodiment discloses a rubber mold with an auxiliary demoulding structure, wherein when a product needs to be injected, the upper mold 14 is pressed against the upper end of the lower mold 11, and then material is added into the molding chamber 12. While the upper mold 14 is pressed against the upper end of the lower mold 11, the connecting plate pushes the sliding plate 27 to slide under the action of the upper mold 14's own gravity, and the sliding plate 27 drives the connecting frame 26 to slide. When the connecting frame 26 moves, the stopper 24 is pulled to slide, so that the stopper 24 slides to the inside of the first fixed tube, and at the same time, the sliding plate 27 drives the guide block 29 to move, and the guide block 29 is inclined to the ejector rod 30. The piston plate is guided so that one end of the ejector rod 30 is inserted into the inner side of the limit frame, thereby fixing the piston plate. When cooling is required, the water pump 17 is started, and the water pump 17 transmits refrigerant to the inside of the transfer tube 16 through the first transmission pipe. Since the upper mold 14 is tightly attached to the upper end of the lower mold 11, the piston plate does not move. Then the refrigerant enters the lower mold 11 through the connecting pipe and the connecting pipe 15. When the lower mold 11 is filled with refrigerant, the refrigerant flows back into the water storage tank 19 through the first return pipe 21, so that the refrigerant circulates and takes away the heat from the inside of the molding chamber 12 during the flow. The product can be cooled quickly. At the same time, the refrigerator 36 can cool the refrigerant in the water tank 19. The overflow weir 35 can increase the cooling time of the refrigerant. When demoulding is required, the upper mold 14 is separated from the upper end of the lower mold 11. Then, under the action of the third return spring 28, the sliding plate 27 returns to the initial position. The sliding plate 27 drives the stopper 24 to return to the initial position through the transfer tube 16, so that the stopper 24 blocks the connecting pipe. One end of the push rod 30 is separated from the inside of the limit frame, and the water pump 17 is started. The input end of the water pump 17 draws liquid from the inside of the water tank 19. Then, the water pump 17 The liquid is transported to the inside of the transfer tube 16. As the water pump 17 continues to transport, the hydraulic pressure inside the transfer tube 16 increases, so that the liquid pushes the piston plate to slide inside the transfer tube 16. The piston plate pushes the push plate 33 to slide inside the molding chamber 12 through the push rod 22, so that the product inside the molding chamber 12 is pushed out, thereby facilitating demoulding. When the push plate 33 is to return to the initial position, the valve 34 is opened to allow the liquid inside the transfer tube 16 to be discharged into the water storage tank 19 through the third transmission pipe and the second reflux pipe 32, thereby discharging the liquid inside the transfer tube 16 and facilitating the transfer tube 16 to return to its initial position.

[0034] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
