[0015] Compared with the prior art, the present utility model has the following beneficial effects:

[0016] 1. In this application, an edge mechanism for tearing the edge of the sealing ring is cooperatively arranged on the upper die and the lower die, so that a rubber material buffer area for decelerating the rubber material during the flowing process is arranged on the side of the rubber material forming area.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific embodiments, structures, features, and their effects of the present utility model as follows.

[0027] Please refer to Figures 1-5As shown, a hydrogen energy sealing ring mold with a new type of trimming groove includes an upper mold and a lower mold. There is a trimming groove structure at the corresponding positions of the upper mold and the lower mold. The processing cavity of the sealing ring is formed by the upper mold and the lower mold to realize the production of the sealing ring, and the connection and blanking of the sealing ring are realized by using the trimming groove structure. Therefore, in this application, the trimming groove structure includes a vertical flash fracture zone 2, a rubber buffer zone 1, and a rubber forming zone 3. By using the above trimming groove structure, an edge trimming structure for the sealing ring is formed to replace the traditional trimming groove structure.

[0028] The traditional trimming groove structure includes an old-fashioned sharp-angle flash fracture part 6. There is an old-fashioned surplus material groove area 4 connected to the side of the old-fashioned sharp-angle flash fracture part 6 through a thin flash easy-to-strip rubber area 5. In this way, the processing cost of the old-fashioned surplus material groove area 4 accounts for one-tenth of the entire processing cycle, and the trimming groove is in a sharp state, which is very easy to cause losses when the product is torn, resulting in wear of the mold and affecting the service life of the mold. At the same time, because the surplus material groove is connected to the position of the old-fashioned surplus material groove area 4 through the thin flash easy-to-strip rubber area 5, it is necessary to perform separate mold removal when discharging the old-fashioned surplus material groove area 4, resulting in low efficiency.

[0029] To solve the above technical problems, in this application, it is realized through the trimming groove structure. Specifically, in this application, first, a rubber buffer zone 1 and a vertical flash fracture zone 2 are arranged on the side of the rubber forming zone 3. The fracture area of the flash in the vertical flash fracture zone 2 is set as a right angle, which increases the strength of the vertical flash fracture zone 2, so that the trimming fracture point is forcibly locked between the product cavity and the vertical flash fracture zone 2. And the increase in the strength of the vertical flash fracture zone 2 greatly improves the mold life.

[0030] Moreover, in this application, due to the existence of the rubber buffer zone 1, the setting of the original old-fashioned surplus material groove area 4 is cancelled, which improves the mold removal efficiency. And the rubber buffer zone 1 can make the rubber be laid flat, thereby improving the product qualification rate, the utilization rate of the rubber, shortening the processing time, and reducing the mold cost.

[0031] In this application, the flash fracture area is innovatively designed as a straight surface, thereby increasing the strength of the flash fracture area, so that the trimming fracture point is forcibly locked between the product cavity and the vertical flash fracture zone 2. And due to the increase in the strength of the vertical flash fracture zone 2, the mold life has been greatly improved. At the same time, it solves the problem of product tearing and increases the product qualification rate.

[0032] As a further embodiment of the present application, the thickness of the stock buffer zone 1 in the present application is adjustable, innovating the stock buffer zone 1 of the flash groove. The stock buffer zone 1 of the flash groove enables the rubber to slow down and form during the flowing process. Moreover, since the stock buffer zone 1 of the flash groove has a certain thickness, the phenomenon of tiny flash can be greatly reduced. And by controlling the thickness of the stock buffer zone 1, the structure of the old-fashioned surplus material groove area 4 can be replaced, the process of machining the surplus material groove can be reduced, and the utilization rate of the rubber material can be improved.

[0033] As a further embodiment of the present application, in order to control the thickness of the stock buffer zone 1, the present application is controlled by using a control mechanism. The control mechanism is located inside the upper mold to control the cavity size of the stock buffer zone 1, so that the thickness of the stock in the stock buffer zone 1 can be controlled, and thus the old-fashioned surplus material groove area 4 can be replaced, enabling the reduction of the process of machining the surplus material groove and the improvement of the utilization rate of the rubber material.

[0034] Therefore, the control mechanism includes an adjustment pressing plate 7 that can move longitudinally. The longitudinal movement of the adjustment pressing plate 7 can adjust the cavity size of the stock buffer zone 1. So the adjustment pressing plate 7 is slidably connected to the upper mold. The adjustment pressing plate 7 is installed on the support base 10, and a driving device is cooperatively arranged on the support base 10 for controlling the height of the support base 10, thereby controlling the height of the adjustment pressing plate 7 to realize the adjustment of the cavity size of the stock buffer zone 1.

[0035] Therefore, the driving device includes a driving turntable 9 and support columns 8. A driving motor is fixed inside the upper mold, and the driving motor is drivingly connected to the driving turntable 9. A plurality of groups of support columns 8 are installed on the driving turntable 9, and the support columns 8 are located below the support base 10. By driving the driving turntable 9 to rotate by the driving motor, the support base 10 is longitudinally supported by the support columns 8, thereby controlling the height of the adjustment pressing plate 7 to realize the adjustment of the cavity size of the stock buffer zone 1.

[0036] When filling the glue, air will be discharged. Common air hole discharges will form hole imprints on the glue buffer area 1, resulting in the breakage of the rubber on the glue buffer area 1 in a thinner state. Therefore, in this application, a pneumatic buffer assembly is provided on the adjusting pressing plate 7. The pneumatic buffer assembly includes an adjusting groove 11. The adjusting groove 11 is opened on the adjusting pressing plate 7. The end of the adjusting groove 11 is fixed with a limiting plate 15. A balance air pipe 12 is arranged on the side above the limiting plate 15. And a balance cylinder 13 is fixed inside the adjusting groove 11. A balance pressing plate 14 is fixed at the output end of the balance cylinder 13. The balance pressing plate 14 is slidably connected with the adjusting groove 11. And the balance pressing plate 14 is in a T shape. The lowest end of the balance pressing plate 14 cooperates with the limiting plate 15. When in use, the balance cylinder 13 is used to drive the balance pressing plate 14 to move longitudinally, so that the lowest end of the balance pressing plate 14 is higher than the highest end of the limiting plate 15, enabling the air to be discharged from the balance air pipe 12, thereby achieving pneumatic balance. When the glue injection is completed, the balance cylinder 13 is used to push the balance pressing plate 14 to move longitudinally, so that the lowest end of the balance pressing plate 14 is balanced with the lowest end of the limiting plate 15, thereby achieving the closing of the balance air holes, and thus being able to solve the formation of hole imprints in the prior art.

[0037] When the upper die and the lower die are separated, since the glue buffer area 1 is thinner, the glue buffer area 1 adheres to the upper die. When the upper die moves away from the lower die, the glue buffer area 1 breaks, causing fluff to adhere to the finished product. Therefore, this application includes a demoulding mechanism. The demoulding mechanism includes a rotating rod 16. The rotating rod 16 is rotatably installed inside the upper die. And a connecting rod 17 is rotatably installed at the end of the rotating rod 16. A limiting slider 21 is fixed at the end of the connecting rod 17. A limiting column 18 is also slidably arranged inside the upper die. A separating plate 19 is fixed at the end of the limiting column 18. A limiting chute 20 is slidably arranged on the separating plate 19. The limiting chute 20 is slidably connected with the limiting slider 21. A pushing platform 22 for cooperating with the rotating rod 16 is arranged on the adjusting pressing plate 7. In this application, the rotating rod 16 is rotatably installed inside the upper die through a torsion spring. When in use, when the adjusting pressing plate 7 moves longitudinally to the highest end, the rotating rod 16 rotates against the acting force of the torsion spring. At this time, the end of the connecting rod 17 is pressed downward. At this time, the connecting rod 17 slides under the action of the limiting chute 20, so that the separating plate 19 presses downward on the glue buffer area 1. At this time, the glue buffer area 1 is separated from the adjusting pressing plate 7, thereby being able to avoid the tearing caused by the glue on the glue buffer area 1 adhering to the adjusting pressing plate 7. Therefore, the demoulding function with the upper die can be stably realized in this application.

[0038] When the utility model is in use, in this application, first, a rubber material buffer zone 1 and a vertical flash fracture zone 2 are arranged on the side of the rubber material forming zone 3. The fracture area of the flash in the vertical flash fracture zone 2 is set as a right angle, which increases the strength of the vertical flash fracture zone 2, so that the tearing edge fracture point is forcibly locked between the product cavity and the vertical flash fracture zone 2. Moreover, the increase in the strength of the vertical flash fracture zone 2 greatly improves the die life.

[0039] And due to the existence of the rubber material buffer zone 1 in this application, the original old-fashioned surplus material groove area 4 is cancelled, which improves the demolding efficiency. The rubber material buffer zone 1 can make the rubber material be laid flat, thereby improving the qualified rate of products, increasing the utilization rate of rubber material, shortening the processing time, and reducing the cost of the die.

[0040] When the thickness of the rubber material buffer zone 1 needs to be adjusted, in this application, the driving motor is used to drive the rotation of the driving turntable 9, so that the support column 8 longitudinally supports the support base 10, thereby controlling the height of the adjustment pressing plate 7 to realize the adjustment of the cavity size of the rubber material buffer zone 1.

[0041] When adjusting the air pressure in the space, the balance cylinder 13 is used to drive the balance pressing plate 14 to move longitudinally, so that the lowest end of the balance pressing plate 14 is higher than the highest end of the limit plate 15, enabling the gas to be discharged from the balance air pipe 12, thereby achieving air pressure balance. After the injection of rubber material is completed, the balance cylinder 13 is used to push the balance pressing plate 14 to move longitudinally, so that the lowest end of the balance pressing plate 14 and the lowest end of the limit plate 15 are balanced, thereby closing the balance air hole and solving the formation of hole prints in the prior art.

[0042] Subsequently, during demolding, when the adjustment pressing plate 7 moves longitudinally to the highest end, the rotating rod 16 rotates against the acting force of the torsion spring. At this time, the end of the connecting rod 17 is pressed downward. At this time, the connecting rod 17 slides under the action of the limit sliding groove 20, so that the separating plate 19 presses downward on the rubber material buffer zone 1. At this time, the rubber material buffer zone 1 is separated from the adjustment pressing plate 7, thereby avoiding the tearing caused by the adhesion of the rubber material on the rubber material buffer zone 1 to the adjustment pressing plate 7. Therefore, the demolding function with the upper die can be stably realized in this application.

[0043] The above are only the preferred embodiments of the present utility model, and do not impose any formal limitations on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present utility model. However, as long as it does not depart from the content of the technical solution of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
