Description

Technical Field

[0001] The utility model relates to the technical field of oil seal production devices, and specifically relates to an oil seal production control device. Background Art

[0002] An oil seal is the customary term for a general seal. Briefly speaking, an oil seal is a mechanical component used to seal oil. It isolates the components that need lubrication in the transmission components from the output components, so as to prevent the lubricating oil from leaking. The seals used for static seals and dynamic seals (generally reciprocating motions) are called oil seals. The representative form of an oil seal is the TC oil seal, which is a double-lip oil seal with a self-tightening spring completely covered by rubber. Generally, the oil seal often refers to this kind of TC skeleton oil seal. Oil seals are widely used in various mechanical equipment, such as the automotive field, etc. They are installed in various parts such as bearings, gearboxes, etc. to prevent fluid leakage and pollution, and ensure the normal operation of the equipment and extend its service life.

[0003] As an indispensable sealing component in mechanical equipment, the quality of the oil seal directly affects the performance and reliability of the equipment. Therefore, the importance of oil seal production is self-evident. By selecting high-quality materials, adopting advanced production processes and strict inspection and testing, it can be ensured that the oil seal has excellent sealing performance and service life, providing reliable guarantee for mechanical equipment. At the same time, oil seal production can also promote the development of the rubber industry and related industries, and contribute to the growth of the national economy.

[0004] Currently, when producing an oil seal, it is necessary to select a suitable mold according to the actually required oil seal, and then process the raw materials required for making the oil seal, such as slitting, folding, etc. After the processing is completed, the raw materials are put into the mold, and the oil seal is formed through a compression and other control devices, then the production of the oil seal can be completed.

[0005] After using the control device to complete the production of the oil seal, the oil seal usually adheres to the outer surface of the upper mold. Therefore, after the worker removes the oil seal, he will hold a pneumatic gun to clean the outer surface of the upper mold, so as to avoid some residual substances adhering to the outer surface of the upper mold and affecting the production of the oil seal. However, this operation will reduce the working efficiency of oil seal production. Summary of the Utility Model

[0006] Based on this, the purpose of the present utility model is to provide an oil seal production control device to solve the technical problem that after using the control device to complete the production of the oil seal, the oil seal usually adheres to the outer surface of the upper mold. Therefore, after the worker removes the oil seal, he will hold a pneumatic gun to clean the outer surface of the upper mold, so as to avoid some residual substances adhering to the outer surface of the upper mold and affecting the production of the oil seal. However, this operation will reduce the working efficiency of oil seal production.

[0007] To achieve the above object, the present utility model provides the following technical solution: An oil seal production control device, including an operating table, a lower mold is slidably connected inside the operating table, and an upper mold that fits with the lower mold is slidably connected to the top of the lower mold.

The bottom of the sleeve is movably connected to a connecting block, and an inner cylinder is fixedly connected to the top of the connecting block. The inner cylinder is connected to a fixed groove through two sets of first springs. A fixed groove is provided on the outer surface of the inner cylinder, and both ends of the fixed groove are slidably connected to telescopic blocks that fit with the fixed groove. Each telescopic block is connected to the fixed groove through a set of second springs. The top of each telescopic block is a bevel structure, and a plurality of air spray holes are provided on the top of the telescopic block.

[0008] By adopting the above technical solution, after the production of the oil seal is completed, the lower mold and the upper mold are driven to move on the operating table. After they move to the middle of a set of movable blocks, the movable blocks are then driven to move upward, so as to synchronously drive the upper mold in the middle of the set of movable blocks to move upward, making the push rod insert into the upper mold to squeeze the inner cylinder and the first spring, then driving the inner cylinder to move downward until the fixed groove on its outer surface is lower than the bottom of the sleeve, then the oil seal at the bottom of the sleeve can be pushed to fall. And since the telescopic block in the fixed groove is not squeezed by the inner wall of the sleeve at this time, the telescopic block can be driven by the second spring to reset and move outward, so that the air spray holes at the bottom of the telescopic block can be completely exposed, then the gas transported into the inner cylinder can be sprayed out through the air spray holes, making the gas play a cleaning effect on the outer surface of the upper mold. Therefore, when removing the produced oil seal, the upper mold can be cleaned synchronously, which is convenient for improving the production efficiency of the oil seal, and thus better producing the oil seal.

[0010] By adopting the above technical solution, when the push rod is connected to the inner cylinder, the air passage in the push rod is connected to the cavity inside the inner cylinder. At this time, the gas pump is used to transport gas into the air passage, so that the gas enters the cavity of the inner cylinder through the air passage, and then enters the inside of the telescopic block through the cavity, so that the gas inside the telescopic block can be sprayed out through the air spray holes at the top of the telescopic block, so that the outer surface of the upper mold can be cleaned by the sprayed gas.

[0011] The present utility model is further configured such that a first gear that fits is fixedly connected to the outer surface of each of the push rods. A second gear meshes with the outer surface of one of the first gears, and the second gear is connected to the output end of a motor through a shaft. The motor is fixedly connected to the top of the operating table through a fixing ring.

[0012] By adopting the above technical solution, the second gear is driven to rotate by the motor, so that one of the first gears rotates, and then the mutually fitting first gears rotate synchronously, thereby driving a plurality of push rods to rotate, which is convenient for better use of the device.

[0013] The present utility model is further configured such that two groups of grooves are provided around the hole at the top of the inner cylinder, and a convex block is movably connected in the groove. The convex block is fixedly connected to the bottom of the push rod.

[0014] By adopting the above technical solution, when the convex block fits with the groove, the push rod can be connected to the inner cylinder. At this time, when the push rod is driven to rotate, the inner cylinder and the telescopic block on the outer surface of the inner cylinder can be synchronously driven to rotate, so that the outer surface of the upper mold can be better cleaned.

[0015] The present utility model is further configured such that a clamping groove is provided on one side of each movable block, and a clamping block that fits with the clamping groove is slidably connected in the clamping groove. The clamping blocks are fixedly connected to both sides of the upper mold, and the clamping blocks are arranged in a "T" shape.

[0017] The present utility model is further configured such that a baffle is fixedly connected to one side of the lower mold, a fixing plate is fixedly connected to the top of the operating table, and the baffle is connected to the fixing plate through a first telescopic rod.

[0018] By adopting the above technical solution, when cleaning the bottom of the upper mold, the position of the lower mold can be moved through the first telescopic rod, and the baffle can prevent the impurities cleaned from the outer surface of the upper mold from falling onto the top of the lower mold, thus affecting the production of the oil seal.

[0019] The present utility model is further configured such that a pressing block is connected to the bottom of the operating table through a hydraulic cylinder.

[0020] By adopting the above technical solution, when the lower mold drives the upper mold to move to one end of the operation table, it is exactly located at the bottom of the pressing block. At this time, the pressing block can be driven to move downward by the hydraulic cylinder, so that pressure can be applied to the lower mold and the upper mold through the pressing block, which is convenient for better production of oil seals.

[0021] To sum up, the main beneficial effects of the present utility model are as follows:

Therefore, after the production of the oil seal is completed by the lower mold and the upper mold, when they are driven to move to the middle of a group of movable blocks on the operation table, the movable blocks and the upper mold are driven to move upward, so that the push rod can be inserted into the upper mold to squeeze the first spring and drive the inner cylinder to move downward. When the fixing groove on the outer surface of the inner cylinder can be lower than the bottom of the sleeve, the oil seal at the bottom of the sleeve can be pushed to fall. At this time, the telescopic block in the fixing groove is not squeezed by the inner wall of the sleeve, and the telescopic block can be driven to move outward by the second spring, so that the gas transported to the inside of the inner cylinder can be ejected through the air injection hole, and the gas can clean the outer surface of the upper mold. Therefore, when the produced oil seal is taken off, the upper mold can be cleaned synchronously, which is convenient for improving the production efficiency of the oil seal and thus better producing the oil seal.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as limiting the present utility model.

[0030] The embodiments of the present utility model will be described below according to its overall structure.

[0031] An oil seal production control device, as Figures 1-5 shown, includes an operation table 1. A lower mold 2 is slidably connected in the operation table 1, and an upper mold 3 is movably connected to the top of the lower mold 2. A damping structure is provided at the connection between the lower mold 2 and the upper mold 3 to increase the friction between the two, so that the upper mold 3 can move synchronously with the lower mold 2. A plurality of sleeves 12 are fixedly connected to the bottom of the upper mold 3. Thus, the production of the oil seal can be completed through the lower mold 2, the upper mold 3 and the sleeves 12. At the same time, a pressing block 5 is connected to the bottom inside the operation table 1 through a hydraulic cylinder 6. Therefore, when the lower mold 2 and the upper mold 3 are connected and move to the bottom of the pressing block 5, the hydraulic cylinder 6 can drive the pressing block 5 to move downward, so as to apply pressure to the lower mold 2 and the upper mold 3, facilitating the completion of the production of the oil seal.

[0032] Furthermore, a baffle 8 is fixedly connected to one side of the lower mold 2, and a fixing plate 4 is fixedly connected to the top of the operation table 1. The baffle 8 is connected to the fixing plate 4 through a first telescopic rod 7. Then, after the production of the oil seal is completed, the second telescopic rod 29 can drive the lower mold 2 and the upper mold 3 to move, so as to complete the cleaning of the upper mold 3.

[0033] Subsequently, a movable block 9 is connected to the top of the operating table 1 through a set of second telescopic rods 29, and the upper mold 3 slides between a set of movable blocks 9. A number of push rods 20 that fit with the sleeves 12 penetrate through the top of the operating table 1 in a movable manner, and holes connected to the sleeves 12 are provided at the top of the upper mold 3, facilitating the better insertion of the push rods 20 into the interiors of the sleeves 12. A connecting block 13 is movably connected to the bottom of the sleeve 12. The connection between the connecting block 13 and the sleeve 12 can be made to fit tightly, preventing the material for producing the oil seal from entering the interior and affecting the production of the oil seal. The top of the connecting block 13 is fixedly connected to an inner cylinder 14. The inner cylinder 14 is connected to the fixed groove 16 through two sets of first springs 15. When the inner cylinder 14 is not squeezed, it can be reset by the first springs 15. Fixed grooves 16 are provided on the outer surface of the inner cylinder 14, and telescopic blocks 17 that fit with the fixed grooves 16 are slidably connected to both ends of each fixed groove 16. Each telescopic block 17 is connected to the fixed groove 16 through a set of second springs 18, and a sealing connection method is adopted between the telescopic block 17 and the fixed groove 16, enabling it to increase the sealing performance between the two while not affecting the movement of the telescopic block 17. When the telescopic block 17 is not squeezed by the interior of the sleeve 12, it can be reset by the second springs 18. Therefore, through the settings of the first springs 15 and the second springs 18, this device can be reused. The top of each telescopic block 17 is of an inclined surface structure, and a number of air jet holes 19 are provided at the top of the telescopic block 17, enabling better jet cleaning of the outer surface of the upper mold 3.

[0034] A clamping groove 10 is provided on one side of each movable block 9, and a clamping block 11 that fits with the clamping groove 10 is slidably connected in the clamping groove 10. A damping structure is provided between the clamping groove 10 and the clamping block 11. Therefore, when the external force is small, the clamping block 11 cannot slide in the clamping groove 10. The clamping block 11 is fixedly connected to both sides of the upper mold 3, and the clamping block 11 is set in a "T" - shaped structure. Through the clamping groove 10 and the clamping block 11, the stability of the upper mold 3 between a set of movable blocks 9 can be increased, facilitating better driving of the upper mold 3 to move.

[0035] Meanwhile, an air pump 24 is provided on the top of the operating table 1, and one end of the push rod 20 is rotatably connected to the bottom of the air pump 24. An air passage 23 is provided in each push rod 20, and an air outlet is provided at the bottom of the air passage 23. A cavity is provided in the inner cylinder 14, and a hole is provided at the top of the inner cylinder 14 and is connected to the air passage 23. One end of the telescopic block 17 is connected to the cavity. Then, the air pump 24 can be used to deliver gas into the push rod 20, and then the gas is delivered into the cavity in the inner cylinder 14 through the air passage 23 in the push rod 20, enabling the gas to enter the interior of the telescopic block 17 through the cavity, and thus the gas can be ejected through the air jet holes 19 at the top of the telescopic block 17 to complete the cleaning of the upper mold 3.

[0036] Therefore, during use, with the matching lower die 2 and upper die 3 provided, after the production of the oil seal is completed by the lower die 2 and the upper die 3, the lower die 2 and the upper die 3 can be driven to move on the operating table 1. After they move to the middle of a set of movable blocks 9, the movable blocks 9 are then driven to move upward, thereby synchronously driving the upper die 3 in the middle of the set of movable blocks 9 to move upward, so that the push rod 20 can be inserted into the upper die 3 to extrude the inner cylinder 14 and the first spring 15, driving the inner cylinder 14 to move downward until the fixing groove 16 on its outer surface is lower than the bottom of the sleeve 12, and the oil seal at the bottom of the sleeve 12 can be pushed to fall. And since the telescopic block 17 in the fixing groove 16 is not squeezed by the inner wall of the sleeve 12 at this time, the telescopic block 17 can be driven by the second spring 18 to reset and move outward, so that the air jet holes 19 at the top of the telescopic block 17 can be completely exposed, and the gas transported to the inside of the inner cylinder 14 can be ejected through the air jet holes 19, so that the gas can clean the outer surface of the upper die 3. Therefore, when removing the produced oil seal, the upper die 3 can be cleaned synchronously, which is convenient for improving the production efficiency of the oil seal.

[0037] And when cleaning the upper die 3, the second telescopic rod 29 can be used to drive the lower die 2 to move to the bottom of the pressing block 5, and the baffle 8 can prevent the impurities cleaned from the outer surface of the upper die 3 from falling onto the top of the lower die 2, thereby affecting the production of the oil seal.

[0038] In this embodiment, a matching first gear 25 is fixedly connected to the outer surface of each push rod 20. A second gear 26 is meshed with the outer surface of one of the first gears 25, and the second gear 26 is connected to the output end of a motor 27 through a shaft. The motor 27 drives the second gear 26 to rotate, thereby synchronously driving the first gear 25 and the push rod 20 to rotate. The motor 27 is fixedly connected to the top of the operating table 1 through a fixing ring 28, so that the position of the motor 27 can be fixed through the fixing ring 28, which is convenient for better use of the motor 27. At the same time, two groups of grooves 21 are provided around the hole at the top of the inner cylinder 14, and a convex block 22 is movably connected in the grooves 21. The convex block 22 is fixedly connected to the bottom of the push rod 20. When the push rod 20 is connected to the inner cylinder 14, the convex block 22 at the bottom of the push rod 20 is inserted into the groove 21 at the top of the inner cylinder 14. Therefore, when the push rod 20 rotates, the inner cylinder 14 can be synchronously driven to rotate through the groove 21 and the convex block 22, which is convenient for the telescopic block 17 in the inner cylinder 14 to clean the outer surface of the upper die 3 and avoid affecting the production of the oil seal.
