Description

Technical Field

[0001] This utility model relates to the field of rubber sealing ring injection mold technology, and in particular to a rubber sealing ring forming device. Background Technology

[0002] A rubber seal is an annular cover composed of one or more parts, fixed to one ring or washer of a bearing and contacting or forming a narrow labyrinth gap with another ring or washer. It prevents lubricating oil leakage and the intrusion of foreign objects. Generator rubber seals prevent leakage of lubricating oil, coolant, and other fluids and gases from the generator, avoiding problems such as poor lubrication, insufficient cooling, and power reduction caused by leakage. They also prevent internal insulation materials from getting damp and short-circuiting, ensuring normal generator operation. Rubber seals are typically made by injection molding rubber material and then cooling it.

[0003] Currently, during the injection molding of rubber seals, the rubber fluid cools down slowly, and the formed seals tend to adhere to the mold during removal, making them difficult to remove. Furthermore, after the mold cools down, re-injecting the rubber fluid into the mold cavity is difficult due to the high temperature of the rubber fluid, hindering the processing and affecting efficiency. To address these issues, we propose a rubber seal forming device. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a rubber sealing ring forming device. It can heat the lower mold base to allow the rubber fluid to flow rapidly and cool the lower mold base to allow the rubber sealing ring to cool and form quickly, ensuring processing efficiency. After the rubber sealing ring is formed, it can control the two half mold bases to move away from each other, making it easy to remove the formed rubber sealing ring and preventing it from adhering to the forming cavity. The operation is simple.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rubber sealing ring forming device includes a worktable, on which a lower mold base is mounted. The lower mold base is composed of two half mold bases arranged symmetrically front to back. The worktable is provided with a drive assembly for moving the two half mold bases. A temperature regulating assembly extending into the lower mold base for cooling and heating is mounted on the worktable. An upper mold base corresponding to the lower mold base is mounted on the worktable via a height adjusting assembly. The upper mold base is provided with an injection port.

[0007] Preferably, the drive assembly includes a mounting plate fixedly connected to the upper end of the worktable. The side wall of the mounting plate is provided with a guide groove. Two T-shaped sliders adapted to the guide groove are slidably connected in the guide groove. The two T-shaped sliders are fixedly connected to the side walls of the two half mold bases respectively. A double-ended screw is rotatably connected in the guide groove. The double-ended screw is threaded through the two T-shaped sliders. The double-ended screw is driven to rotate by a drive motor mounted on the upper end of the worktable.

[0008] Preferably, the temperature regulating component includes a cold water tank and a hot water tank installed on the upper part of the workbench. The cold water tank and the hot water tank are respectively equipped with U-shaped cold water pipes and U-shaped hot water pipes extending into two half-mold seats on the lower mold seat. The section of the U-shaped cold water pipe and the U-shaped hot water pipe located outside the lower mold seat are both telescopic flexible hoses.

[0009] Preferably, both the cold water tank and the hot water tank include a water storage chamber and a water return chamber. The two ends of the U-shaped cold water pipe and the U-shaped hot water pipe extend into the corresponding water storage chamber and the water return chamber, respectively, and water is transported by a water pump. Both the cold water tank and the hot water tank are equipped with an inlet pipe extending into the corresponding water storage chamber and a drain pipe that communicates with the corresponding water return chamber.

[0010] Preferably, the height adjustment assembly includes two vertical rods fixedly connected to the upper end of the worktable, and a connecting plate slidably connected to both vertical rods is sleeved on the two vertical rods.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. This rubber sealing ring forming device allows hot water to flow inside a U-shaped hot water pipe, which heats the lower mold base. It controls the upper mold base to move down and contact the lower mold base, and injects rubber raw material between the lower and upper mold bases through the injection port. The high-temperature rubber fluid flows rapidly to initially form the rubber ring. Cold water flows inside a U-shaped cold water pipe, which cools the lower mold base, thereby allowing the rubber sealing ring to cool and form quickly, ensuring processing efficiency.

[0014] 2. In this rubber sealing ring forming device, after the rubber sealing ring is formed, the starting cylinder drives the upper mold seat to move upward, and controls the drive motor to drive the double-headed screw to rotate. Under the thread meshing action, the two T-shaped sliders drive the two half mold seats to move away from each other, which makes it easier to remove the formed rubber sealing ring and avoids it from adhering to the forming cavity. The operation is simple. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5A rubber sealing ring forming device includes a worktable 1, on which a lower mold base 2 is mounted. The lower mold base 2 consists of two semi-mold bases symmetrically arranged front and rear. Both semi-mold bases share a forming cavity for forming the rubber sealing ring. Sealing gaskets are provided on the opposing sidewalls of the two semi-mold bases, ensuring a seal between their opposing sidewalls when the two semi-mold bases abut, preventing leakage of the rubber fluid. A driving assembly for moving the two semi-mold bases is provided on the worktable 1. The driving assembly includes a mounting plate 3 fixedly connected to the upper end of the worktable 1. The side wall of 3 is provided with a guide groove, and two T-shaped sliders 4 that are adapted to it are slidably connected in the guide groove. The two T-shaped sliders 4 are fixedly connected to the side walls of the two half mold bases respectively. A double-headed screw 5 is rotatably connected in the guide groove. The double-headed screw 5 is threaded through the two T-shaped sliders 4. The double-headed screw 5 is driven to rotate by a drive motor 6 installed on the upper end of the worktable 1. The drive motor 6 drives the double-headed screw 5 to rotate, which can make the two T-shaped sliders 4 move the two half mold bases closer or further apart under the thread meshing action, so as to facilitate the removal of the molded rubber sealing ring.

[0023] A temperature regulating component is installed on the workbench 1, extending into the lower mold base 2 to cool and heat the lower mold base 2. The temperature regulating component includes a cold water tank 8 and a hot water tank 9 installed on the upper end of the workbench 1. U-shaped cold water pipes 10 and U-shaped hot water pipes 11 are respectively installed on the cold water tank 8 and the hot water tank 9, extending into the two half mold bases on the lower mold base 2. The section of the U-shaped cold water pipes 10 and the U-shaped hot water pipes 11 located outside the lower mold base 2 are both telescopic hoses, so that when the two half mold bases are close to each other or far apart, the U-shaped cold water pipes 10 and the U-shaped hot water pipes 11 can extend and retract to adapt to the movement of the half mold bases and ensure the normal operation of the processing work.

[0024] Both the cold water tank 8 and the hot water tank 9 include a water storage chamber and a water return chamber. The two ends of the U-shaped cold water pipe 10 and the U-shaped hot water pipe 11 extend into the corresponding water storage chamber and water return chamber, respectively, and water is transported by a water pump. The lower mold base 2 and the U-shaped cold water pipe 10 and the U-shaped hot water pipe 11 are made of materials with good thermal conductivity. The water pump draws water out of the water storage chamber and flows through the U-shaped cold water pipe 10 or the U-shaped hot water pipe 11. After being cooled or heated by the lower mold base 2, the water flows back to the water return chamber for storage. Both the cold water tank 8 and the hot water tank 9 are equipped with inlet pipes that extend into the corresponding water storage chambers and drain pipes that are connected to the corresponding water return chambers. Control valves are installed on both the inlet pipes and the drain pipes.

[0025] An upper mold base 15 corresponding to the lower mold base 2 is installed on the worktable 1 via a height adjustment assembly. The upper mold base 15 is provided with an injection port. The height adjustment assembly includes two vertical rods 12 fixedly connected to the upper end of the worktable 1. A connecting plate 13 is slidably connected to the two vertical rods 12. The upper mold base 15 is fixedly connected to the side wall of the connecting plate 13. The two vertical rods 12 can restrict the connecting plate 13, so that the connecting plate 13 can move up and down stably, thereby driving the upper mold base 15 to move up and down stably. A cylinder 14 is installed between the worktable 1 and the connecting plate 13. The cylinder 14 can drive the upper mold base 15 to move up and down stably.

[0026] Multiple limiting posts 7 are fixedly connected to the lower mold base 2, and multiple insertion holes 16 are opened through the upper mold base 15. The multiple insertion holes 16 correspond to the multiple limiting posts 7 respectively, so that the upper mold base 15 and the lower mold base 2 can be aligned vertically, thereby ensuring the processing quality of the rubber sealing ring.

[0027] The functional principle of this utility model can be explained through the following operation methods:

[0028] In this utility model, when the rubber sealing ring forming device is in use, the water pump in the hot water tank 9 is started to make hot water flow in the U-shaped hot water pipe 11 to heat the lower mold base 2. The cylinder 14 is started to drive the upper mold base 15 to move downward, so that multiple limiting posts 7 pass through the corresponding insertion holes 16 until the upper mold base 15 contacts the lower mold base 2. The rubber raw material is injected into the space between the lower mold base 2 and the upper mold base 15 through the injection port by the extruder set in advance. The high temperature rubber fluid flows rapidly to ensure processing efficiency. The water pump in the cold water tank 8 is started to make cold water flow in the U-shaped cold water pipe 10 to cool the lower mold base 2, thereby enabling the rubber sealing ring to cool and form, ensuring the forming efficiency of the rubber sealing ring.

[0029] The starting cylinder 14 drives the upper mold base 15 to move upward, and the drive motor 6 drives the double-headed screw 5 to rotate. Under the engagement of its threads, the two T-shaped sliders 4 can move the two half mold bases away from each other, which makes it easier to remove the formed rubber sealing ring and prevent it from adhering to the molding cavity. The two half mold bases are brought closer together. By repeating the above work, the next rubber sealing ring can be formed. The operation is simple and ensures work efficiency.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
