Description

Technical Field

[0001] The utility model relates to the technical field of sealing ring injection molding, in particular to a rubber sealing ring injection molding mold. Background Art

[0002] The rubber sealing ring is an annular cover composed of one or more parts, which is fixed on a ring or washer of the bearing and contacts with another ring or washer or forms a narrow labyrinth gap to prevent the leakage of lubricating oil and the intrusion of foreign objects.

[0003] The patent number CN221314906U discloses an injection mold for a rubber seal ring, which relates to the technical field of rubber seal ring injection molds, including a workbench, a lower rubber seal ring mold is arranged in the middle of the workbench, and auxiliary mechanisms are symmetrically arranged on both sides of the lower rubber seal ring mold; a bracket is arranged on one side of the top of the workbench, a mounting plate is arranged at one end of the top of the bracket, a hydraulic telescopic rod is arranged at the top of the mounting plate, the bottom end of the piston rod of the hydraulic telescopic rod passes through the bottom end of the mounting plate and is provided with an upper rubber seal ring mold, a blanking port is provided at the top of the workbench, a blanking channel is provided on the other side of the workbench, and one end of the blanking channel extends to the inside of the blanking port. The utility model has a reasonable and reliable structure, is easy to operate, and can quickly injection mold the rubber material through the injection molding process, improve production efficiency, ensure the consistency of the size and shape of the rubber seal ring, and ensure the stable quality of the product.

[0004] The above device has certain shortcomings when in use: when the rubber sealing ring is taken out, the electric telescopic rod drives the rubber sealing ring mold to move toward the two ends of the workbench, and the formed rubber sealing ring falls into the blanking port. When the half mold moves toward the two ends, the mounting rod slowly rises from low to high during the movement of the inner wall of the guide groove. The rubber sealing ring may be stretched and engaged with the half mold groove in the inner wall of the half mold groove. Sometimes, the half mold is opened but the rubber sealing ring is stretched and does not detach from the half mold groove, resulting in the inability to fall into the blanking port.

[0005] Therefore, the utility model provides a rubber sealing ring injection mold to solve the above problems. Utility Model Content

[0022] Beneficial effects

[0023] The utility model provides an injection mold for rubber sealing rings. Compared with the prior art, it has the following

[0024] Beneficial effects:

[0025] (1) The injection mold for the rubber sealing ring closes the male mold and the female mold by pushing with a hydraulic rod. The sealing ring enters the sealing groove. The external injection molding machine conveys the rubber material into the injection pipe. The movable end of the hydraulic rod contracts to drive the separation of the male mold and the female mold. The electric telescopic rod pushes the sealing block to move upward on the inner wall of the through port, pushing up the formed rubber sealing ring inside the female mold to break away from contact with the female mold and with a height greater than that of the hook. The electric slider drives the connecting seat and the mounting bracket to move rightward along the outer wall of the linear slide rail. When the moving plate and the hook move to the lower position of the rubber sealing ring, the electric push rod pushes the moving plate and the hook to the bottom position of the rubber sealing ring. The blower conveys cold air into the inside of the conveying pipe through the movable hose and cools the rubber sealing ring through the air outlet pipe. The electric telescopic rod drives the sealing block to descend into the inner wall of the through port. The sealing block breaks away from contact with the rubber sealing ring and hangs on the hook. The electric slider drives the connecting seat and the mounting bracket to continue moving rightward along the outer wall of the linear slide rail. The male mold and the female mold cooperate to continue the injection molding production work of the rubber sealing ring. After the rubber sealing ring hanging on the hook is cooled, it is taken off and placed inside the placement frame and separated by the partition plate. This enables the formed rubber sealing ring to be quickly pushed up and separated from contact with the female mold after injection molding, and at the same time, it can be cooled and the rubber sealing ring can be transferred. During the cooling waiting time, the injection molding of the rubber sealing ring can continue, improving production efficiency, and preventing the rubber sealing ring from being stuck and stretched during demolding.

[0039] In the embodiment of the present utility model, the purpose of such a setting is that, with the setting of the mold clamping assembly 5, after the punch 4 is pushed downward by the hydraulic rod 52 to be clamped with the die 3, through the mutual cooperation of the sealing ring 53 and the sealing groove 54, the mold clamping tightness between the punch 4 and the die 3 can be increased. After cooling, the rubber sealing ring can be placed inside the placing frame 7.

[0040] Meanwhile, the content not described in detail in this specification belongs to the prior art well known to those skilled in the art.

[0041] During operation, first, connect the hydraulic rod 52, linear slide rail 61, fan 62, electric slider 64, electric push rod 67, and electric telescopic rod 613 to the main controller 2 through an external power supply, and connect the discharge pipe of the external injection molding machine to the injection pipe 9. Drive the electric slider 64 to slide on the outer wall of the linear slide rail 61 through the main controller 2, and drive the mounting bracket 66 to move to the left position of the linear slide rail 61. Then, control the hydraulic rod 52 to push the punch 4 downward to close the mold with the die 3 through the main controller 2. The punch 4 drives the sealing ring 53 into the sealing groove 54, increasing the sealing performance between the die 3 and the punch 4. After the mold is closed, the external injection molding machine transports the rubber material into the injection pipe 9. After the rubber sealing ring is formed, the movable end of the hydraulic rod 52 contracts to drive the punch 4 and the die 3 to separate, and the sealing ring 53 and the sealing groove 54 are disengaged. Control the electric telescopic rod 613 to push the sealing block 615 to move upward in the inner wall of the through hole 614 through the main controller 2. Thus, the sealing block 615 lifts the formed rubber sealing ring in the die 3 to disengage it from the die 3. Moreover, the height that the sealing block 615 lifts the rubber sealing ring is greater than that of the hook 69. Control the linear slide rail 61 and the electric slider 64 to cooperate with each other through the main controller 2, so that the electric slider 64 drives the connecting seat 65 and the mounting bracket 66 to start moving to the right along the outer wall of the linear slide rail 61. When the mounting bracket 66 moves, it drives the electric push rod 67, the moving plate 68, the hook 69, the conveying pipe 610, the T-shaped frame 611, and the air outlet pipe 612. When the moving plate 68 and the hook 69 move to the lower position of the rubber sealing ring, drive the moving plate 68 and the hook 69 to start moving forward through the electric push rod 67, so that the hook 69 is located at the bottom of the rubber sealing ring. And when the moving plate 68 moves, it drives the limiting rod 618 to move to prevent position deviation during movement. Start the fan 62 and transport cold air into the conveying pipe 610 through the flexible hose 63, and cool the rubber sealing ring through the air outlet pipe 612. The movable end of the electric telescopic rod 613 drives the sealing block 615 to descend into the inner wall of the through hole 614. At the same time, the sealing block 615 is disengaged from the rubber sealing ring. After the rubber sealing ring is hung on the hook 69, drive the connecting seat 65 and the mounting bracket 66 to continue moving to the right along the outer wall of the linear slide rail 61 through the electric slider 64. At the same time, the die 3 and the punch 4 can cooperate with each other to continue the injection production work of the rubber sealing ring. After the rubber sealing ring hung on the hook 69 is cooled, take it off and put it into the placement frame 7 and separate it through the partition plate 8.
