Description

Technical Field

[0001] This utility model relates to the field of rubber oil seal processing technology, specifically a vulcanization device for rubber oil seal processing. Background Technology

[0002] Rubber oil seal vulcanization is an important step in the production of rubber products. It significantly enhances the mechanical strength and service life of the products by transforming the linear molecular structure of raw rubber into a three-dimensional network structure.

[0003] Traditional oil-sealed vulcanizing machines are inefficient and prone to prolonged continuous operation, which shortens their lifespan, increases maintenance frequency, raises costs, and causes inconvenience for users.

[0004] As disclosed in Chinese Patent CN206242331U, a high-efficiency oil seal vulcanizing machine is constructed using a base. A first telescopic rod is fixedly connected to the bottom of the base's inner cavity. Second telescopic rods are fixedly connected to the bottom of the base's inner cavity on both sides of the first telescopic rod. The top of each second telescopic rod penetrates the top of the base and extends to the outside of the base. A top plate is fixedly connected to the top of the second telescopic rod. A storage box is fixedly connected to the left side of the top of the top plate, and a feeding funnel is connected to the top of the storage box. Through the coordinated use of the first and second telescopic rods, the first conduit, the slurry pump, and the second conduit, as well as improvements to the heating device, molding device, and processing device, the working efficiency of the oil seal vulcanizing machine is increased, avoiding excessively long continuous working times due to low efficiency.

[0005] However, in existing technologies, air is usually vented during the vulcanization process of rubber oil seals through the gaps between vulcanization molds. This method can cause overflow of the rubber material during molding, affecting subsequent processing. If the air is directly released through the vent holes, dust can easily enter the mold, thus affecting the processing effect.

[0006] Therefore, we urgently need to provide a vulcanization device for processing rubber oil seals. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1:

[0029] Due to existing technologies, vulcanization devices may experience rubber overflow and dust entering the mold during the mold closing process. Please refer to... Figures 1-6 The embodiment provides a vulcanizing device for processing rubber oil seals, which can effectively prevent the overflow of rubber material during the vulcanization molding process and effectively prevent dust from entering the mold and affecting the vulcanization molding effect. The vulcanizing device for processing rubber oil seals includes a worktable 1, a mold adjustment device installed in the middle of the top surface of the worktable 1, a mold closing device installed near the right end of the top surface of the worktable 1, and limit auxiliary devices installed on the front and back of the mold closing device near the bottom.

[0030] The mold closing device includes an venting mechanism and a mold closing mechanism. The mold closing mechanism is installed at the top and bottom of the venting mechanism. The venting mechanism includes an upper mold 204, with an vent pipe 206 installed on the top surface of the upper mold 204. A memory spring 207 is installed inside the vent pipe 206, and a sealing block 208 is installed at the top of the memory spring 207. The mold closing mechanism includes a processing frame 201, with a hydraulic cylinder 202 installed in the middle of the top surface of the processing frame 201. A heating layer 203 is installed at the output end of the hydraulic cylinder 202, and a stop plate 205 is provided at the bottom of the heating layer 203.

[0031] The upper mold 204 is fixedly installed on the bottom surface of the heating layer 203. The flow stop plate 205 is fixedly installed on the bottom surface of the upper mold 204. The outer surface of the exhaust pipe 206 is connected to the inner surface of the heating layer 203 through a circular hole. The bottom end of the memory spring 207 is fixedly connected to the middle of the inner wall of the exhaust pipe 206. The outer surface of the sealing block 208 is slidably connected to the inner wall of the exhaust pipe 206. The interior of the exhaust pipe 206 is connected to the molding cavity between the lower mold 107 and the upper mold 204. The shape and size of the flow stop plate 205 are adapted to the shape and size of the flow stop groove on the top of the lower mold 107.

[0032] By setting up the mold closing device, during the vulcanization molding of the rubber oil seal, the memory spring 207 is extended during the heating process, thereby pushing the sealing block 208 to slide away from the inside of the exhaust pipe 206, so that the exhaust pipe 206 can be used for exhaust, and the sealing block 208 can effectively prevent dust from entering the mold.

[0033] When using the mold closing device for vulcanization molding, the hydraulic cylinder 202 is activated to lower the heating layer 203 and the upper mold 204, thereby closing the upper mold 204 with the lower mold 107. During the mold closing process, the stop plate 205 is inserted into the stop groove on the top surface of the lower mold 107 to effectively prevent the rubber material from overflowing during vulcanization molding. After mold closing, the heating layer 203 is used for heating. During the heating and vulcanization molding process, air is exhausted through the exhaust pipe 206. During this process, the memory spring 207 is heated and extends, thereby pushing the sealing block 208 out through the top of the exhaust pipe 206, facilitating the exhaust through the exhaust pipe 206 and preventing gas from affecting the quality of the rubber material vulcanization molding. After the mold closing process, during the material discharge process, the temperature decreases, and the memory spring 207 is cooled and contracts, thereby driving the sealing block 208 to seal the exhaust pipe 206, preventing dust from entering the mold through the exhaust pipe 206 and effectively reducing the impact of dust on subsequent processing operations.

[0034] Example 2:

[0035] Based on Embodiment 1, since the loading and unloading processes in the prior art are all located at the bottom of the mold closing device, it is inconvenient to load and unload materials and is prone to accidental operation and danger. This embodiment provides a vulcanizing device for rubber oil seal processing. By adjusting the loading and unloading position of the mold, the inconvenience of loading and unloading materials and the risk of accidental operation and danger can be effectively avoided. The vulcanizing device for rubber oil seal processing includes an asynchronous motor 101, a transmission component 102 connected to the output end of the asynchronous motor 101, a slider 103 installed in the middle of the outer surface of the transmission component 102, a heating chamber 105 installed at the top of the slider 103, limit blocks 104 installed near the four corners of the bottom surface of the heating chamber 105, a heating tube 106 installed inside the heating chamber 105, and a lower mold 107 installed on the top surface of the heating chamber 105. The asynchronous motor 101 is detachably mounted on the top right side of the worktable 1. The outer surface of the slider 103 is slidably connected to the inner wall of a rectangular groove in the middle of the top surface of the worktable 1. The outer surface of the limiting block 104 is slidably connected to the inner wall of a convex groove in the top surface of the worktable 1 near the front and back ends. The transmission component 102 consists of a threaded rod and a threaded cylinder. The right end of the threaded rod is connected to the output end of the asynchronous motor 101. The outer surface of the threaded rod is threadedly connected to the inner wall of the threaded cylinder. The outer surface of the threaded cylinder is fixedly connected to the middle of the slider 103.

[0036] The limiting auxiliary device includes fixed rods 301. Two fixed rods 301 are fixedly mounted at one end close to each other, with a limiting box 302. A positioning block 303 is connected inside the limiting box 302. An electric push rod 304 is provided on the left side of the fixed rods 301, and an impact block 305 is installed at the output end of the electric push rod 304. The end of the fixed rod 301 away from the limiting box 302 is fixedly connected to the bottom end of the processing frame 201. The end of the positioning block 303 away from the limiting box 302 is fixedly connected to the lower mold 107. The electric push rod 304 is installed on the front and back of the processing frame 201, near the bottom.

[0037] With the mold adjustment device and the limiting auxiliary device, the lower mold 107 is moved by the transmission component 102 and the slider 103 to facilitate loading and unloading. The sliding limiting connection of the positioning block 303 and the limiting box 302 facilitates the mold closing and positioning of the lower mold 107. The electric push rod 304 drives the impact block 305 to facilitate the venting of the rubber material inside the lower mold 107.

[0038] When loading and unloading rubber materials and vulcanized products, the asynchronous motor 101 is started to drive the transmission component 102. The output end of the asynchronous motor 101 drives the threaded rod to rotate. The threaded connection between the outer surface of the threaded rod and the inner wall of the threaded cylinder causes the threaded cylinder to drive the slider 103 to slide. The slider 103 drives the heating chamber 105, the heating tube 106, and the lower mold 107 to move. During the movement, the outer surface of the limiting block 104 is slidably connected to the inner wall of the convex groove opened near the front and back ends of the top surface of the worktable 1, thereby ensuring the stability during the movement. This moves the lower mold 107 to the top of the worktable 1 away from the bottom of the processing frame 201, facilitating safe loading and unloading operations. During the mold closing and vulcanization process, the installation of the heating tube 106 inside the heating chamber 105, in conjunction with the heating layer 203, heats and vulcanizes the rubber material from the top of the upper mold 204 and the bottom of the lower mold 107, effectively improving the efficiency of production and processing. During the mold closing process, the positioning blocks 303 installed on the front and right sides of the lower mold 107 are connected to the sliding limit box 302 to ensure the accuracy of the mold closing process. During the mold closing and vulcanization molding process, the electric push rod 304 is activated to drive the impact block 305 to impact the lower mold 107, thereby using the vibration generated by the collision to help the air bubbles inside the rubber material to be discharged, effectively improving the quality of vulcanization molding.
