Description

Technical Field

[0001] The utility model relates to the technical field of vulcanizing machine devices, in particular to a vulcanizing machine workbench. Background Art

[0002] Vulcanizer is an important processing equipment widely used in rubber, plastic and other industries. It is mainly used for vulcanization of various rubber and plastic products. Its working principle is: it mainly uses high temperature and vulcanizing agent to heat rubber or plastic to cross-link the chemical bonds between its molecules, so that the material has better strength and wear resistance. At the same time, during the vulcanization process, the vulcanizer will exert a certain pressure on the product to ensure the density and quality of the product.

[0003] The vulcanizer has multiple functional characteristics to meet the needs of different materials and production processes. It is usually equipped with an advanced temperature control system that can accurately adjust the vulcanization temperature to ensure the quality of the product. In addition, the vulcanizer also has functions such as timed mold locking, automatic pressure replenishment, automatic timing, and time alarm, making the operation easier and safer. In short, as an important processing equipment, the vulcanizer plays an irreplaceable role in the production process of rubber and plastic products.

[0004] At present, when using a vulcanizer, it is usually necessary to put the rubber or plastic product to be processed into a mold, and then heat it at a high temperature, and apply a certain pressure to the rubber or plastic product while heating, so as to increase the density and quality of the rubber or plastic product, and make the material have better strength and wear resistance.

[0005] After the rubber or plastic products are processed by the vulcanizer, they need to be cooled down because they are heated at high temperature and then molded. At present, most of them are cooled down by natural cooling, which can easily lead to a high internal temperature of the rubber or plastic products due to their short cooling time, thereby reducing product quality. Utility Model Content

[0006] Based on this, the purpose of the utility model is to provide a vulcanizing machine workbench to solve the problem that rubber or plastic products are heated and then molded at high temperatures, so they need to be cooled. At present, most of them are cooled by natural cooling, which easily leads to a short cooling time, making the internal temperature of the rubber or plastic products higher, thereby reducing the technical problem of product quality.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vulcanizing machine workbench, comprising an operating table, a lower mold is slidably connected in the operating table, the lower mold is connected to one side of the operating table through a first hydraulic cylinder, the top of the lower mold is movably connected to the upper mold, and a pushing structure is provided on the upper mold, both sides of the upper mold are movably connected to U-shaped blocks, and the top of the U-shaped block is connected to the operating table through a second hydraulic cylinder, the bottom of the operating table is fixedly connected to a guide block through a connecting rod, and one side of the guide block is fixedly connected to a fixed block, both sides of the fixed block are rotatably connected to movable covers through a first rotating shaft, one side of the guide block is rotatably connected to a second rotating shaft, and the outer surfaces of the first rotating shaft and the second rotating shaft are connected through a transmission belt, the outer surface of the second rotating shaft is fixedly connected to a gear, and the outer surface of the gear is meshed with a rack, the top of the rack is fixedly connected to the bottom of the U-shaped block, refrigeration devices are provided on both sides of the fixed block, and the fixed block is provided with a plurality of holes.

[0008] By adopting the above technical scheme, when the second hydraulic cylinder drives the upper mold to move upward through the U-shaped block, it can simultaneously drive the rack to move upward, and then drive the gear and the second rotating shaft to rotate, so that the first rotating shaft can rotate synchronously through the transmission belt and the second rotating shaft, so the movable cover can be opened by the rotation of the first rotating shaft. At this time, the rubber or plastic products on the surface of the upper mold fall off through the pushing structure, and the rubber or plastic products can enter the fixed block through the guide block, and then the upper mold and the rack are driven downward by the second hydraulic cylinder, which can drive the gear and the second rotating shaft to reverse, so that the first rotating shaft drives the movable cover to rotate synchronously, so that a sealed space can be formed by the movable cover and the fixed block, and then cold air is transported into the fixed block by the refrigeration device, so that the rubber or plastic products in the fixed block can be quickly cooled down, thereby shortening the cooling time, improving product quality, and facilitating better vulcanization of rubber or plastic products.

[0009] The utility model is further configured as follows: the pushing structure includes a movable block movably connected to the bottom of the upper mold, and the movable block is connected to the upper mold through a third hydraulic cylinder, the movable block is configured as a cavity structure, and a plurality of air outlet holes are provided at the bottom of the movable block, an air pump is provided on the top of the upper mold, and the cavity and the air pump are connected through a connecting pipe.

[0010] By adopting the above technical solution, the third hydraulic cylinder drives the movable block to move downward, so that the upper mold can be separated from the manufactured rubber or plastic product through the movable block. At the same time, gas is transported into the cavity through the air pump and the connecting pipe and then sprayed out through the air outlet, thereby preventing the rubber or plastic product from adhering to the bottom of the movable block and affecting the falling of the rubber or plastic product.

[0011] The utility model is further configured such that a group of baffles are slidably connected inside the fixed block, and the positions of the baffles match the positions of the holes, each of the baffles is connected to the fixed block by a spring, and the top of each baffle is movably connected to a group of fixing rods, and the fixing rods are fixedly connected to the bottom of the movable cover.

[0012] By adopting the above technical solution, when the movable cover and the fixed block form an enclosed space, the baffle can be squeezed by the fixed rod, so that the baffle moves downward to squeeze the spring, so that the hole is not blocked. At this time, the refrigeration device can transport cold air to the fixed block through the hole, which is convenient for cooling the product. At the same time, when the movable cover is rotated, the fixed rod can be rotated synchronously. The baffle is not squeezed by the fixed rod and can be reset by the spring so that it can block the hole again, making it impossible for the refrigeration device to transport cooling to the fixed block, thereby reducing the waste of cold air and saving resources.

[0013] The utility model is further configured that the top of the guide block is an inclined surface structure, and the top of the guide block is rotatably connected to a plurality of rollers.

[0014] By adopting the above technical solution, the rubber or plastic product can fall to the top of the guide block, and then enter the fixed block through the inclined structure and roller of the guide block to cool down.

[0015] The utility model is further configured that the connecting pipe is configured to be made of a corrugated pipe material.

[0016] By adopting the above technical solution, when the third hydraulic cylinder pushes the movable block to move downward, the connecting pipe can be stretched by the movable block, thereby avoiding affecting the movement of the movable block and facilitating the delivery of gas into the movable block through the connecting pipe.

[0017] The utility model is further configured such that the baffle is configured as an "I"-shaped structure.

[0018] By adopting the above technical solution, the movement direction of the baffle can be limited, thereby preventing the baffle from sliding out or falling from the fixing block, which would affect the use of the device.

[0019] In summary, the utility model mainly has the following beneficial effects:

[0020] The utility model meshes mutually between the gear and the rack, so when the second hydraulic cylinder drives the upper mold to move upward through the U-shaped block, it can synchronously drive the rack to move upward, and then drive the second rotating shaft and the first rotating shaft to rotate, so that the movable cover is opened. At this time, the rubber or plastic product on the surface of the upper mold is dropped into the interior of the fixed block through the pushing structure, and then the upper mold and the rack are driven downward by the second hydraulic cylinder, so that the movable cover can be rotated, so that a sealed space can be formed by the movable cover and the fixed block, and then cold air is transported into the fixed block by the refrigeration device, so that the rubber or plastic product in the fixed block can be quickly cooled, thereby shortening the cooling time, improving product quality, and facilitating better vulcanization of the rubber or plastic product.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0027] The following describes an embodiment of the utility model based on its overall structure.

[0028] A vulcanizing machine workbench, such as Figure 1-4As shown, it includes an operating table 1, in which a lower mold 3 is slidably connected, and the lower mold 3 is connected to one side of the operating table 1 through a first hydraulic cylinder 2. The top of the lower mold 3 is movably connected to an upper mold 4, and a pushing structure is provided on the upper mold 4. The lower mold 3 and the upper mold 4 can be driven to move in the horizontal direction by the first hydraulic cylinder 2. At the same time, U-shaped blocks 5 are movably connected on both sides of the upper mold 4, and the top of the U-shaped block 5 is connected to the operating table 1 through a second hydraulic cylinder 6. When the first hydraulic cylinder 2 drives the lower mold 3 and the upper mold 4 to move, until the upper mold 4 moves into the U-shaped block 5, the second hydraulic cylinder 6 can be used to drive the U-shaped block 5 and the upper mold 4 to move upward, thereby separating the lower mold 3 and the upper mold 4, so as to facilitate the removal of the rubber or plastic products made in the lower mold 3 and the upper mold 4.

[0029] Then, a guide block 13 is fixedly connected to the bottom of the operating table 1 through a connecting rod 12, and a fixed block 15 is fixedly connected to one side of the guide block 13. A movable cover 16 is rotatably connected to both sides of the fixed block 15 through a first rotating shaft 17. A second rotating shaft 18 is rotatably connected to one side of the guide block 13, and the outer surfaces of the first rotating shaft 17 and the second rotating shaft 18 are connected through a transmission belt 19. A gear 20 is fixedly connected to the outer surface of the second rotating shaft 18, and a rack 21 is meshed with the outer surface of the gear 20. The top of the rack 21 is fixedly connected to the bottom of the U-shaped block 5. When the second hydraulic cylinder 6 drives the U-shaped block 5 to move, the rack 21 can be moved synchronously, so that the driving gear 20 drives the second rotating shaft 18 to rotate, so that the first rotating shaft 17 can be rotated synchronously through the transmission belt 19, so that the movable cover 16 can be driven to open or close. Refrigeration devices 22 are arranged on both sides of the fixed block 15, and the fixed block 15 is provided with a plurality of holes 23, so that the refrigeration device 22 can transport cold air to the fixed block 15 through the holes 23.

[0030] The pushing structure includes a movable block 7 movably connected to the bottom of the upper mold 4, and the movable block 7 is connected to the upper mold 4 through a third hydraulic cylinder 27. The movable block 7 can be pushed downward by the third hydraulic cylinder 27, so that the rubber or plastic product can fall from the upper mold 4. The movable block 7 is set as a cavity 9 structure, and a plurality of air outlets 8 are set at the bottom of the movable block 7. An air pump 11 is set at the top of the upper mold 4, and the cavity 9 and the air pump 11 are connected by a connecting pipe 10. Gas can be transported into the cavity 9 through the air pump 11 and the connecting pipe 10, and then the gas is ejected through the air outlet 8, so that the rubber or plastic product can be prevented from adhering to the bottom of the movable block 7, so that the rubber or plastic product can fall from the upper mold 4.

[0031] At the same time, the top of the guide block 13 is an inclined structure, which can guide the rubber or plastic products, and the top of the guide block 13 is rotatably connected to a plurality of rollers 14, which can reduce the friction between the rubber or plastic products and the guide block 13 through the rollers 14, so that the rubber or plastic products can enter the interior of the fixed block 15 for rapid cooling.

[0032] Therefore, when in use, through the mutual meshing between the gear 20 and the rack 21, when the second hydraulic cylinder 6 drives the upper mold 4 to move upward through the U-shaped block 5, the rack 21 can be synchronously driven to move upward, and the gear 20 and the second rotating shaft 18 can be driven to rotate, so that the first rotating shaft 17 can rotate synchronously with the second rotating shaft 18 through the transmission belt 19, so that the movable cover 16 can be opened by the rotation of the first rotating shaft 17, and at this time, the rubber or plastic products on the surface of the upper mold 4 are dropped by the pushing structure, and the rubber or plastic products can be pushed through the guide block 13. The upper mold 4 and the rack 21 can then be driven downward by the second hydraulic cylinder 6, which can drive the gear 20 and the second rotating shaft 18 to reverse, so that the first rotating shaft 17 drives the movable cover 16 to rotate synchronously, so that a sealed space can be formed by the movable cover 16 and the fixed block 15, and then cold air is transported into the fixed block 15 by the refrigeration device 22, so that the rubber or plastic products in the fixed block 15 can be quickly cooled, thereby shortening the cooling time, improving product quality, and facilitating better vulcanization of rubber or plastic products.

[0033] A group of baffles 24 are further slidably connected in the fixed block 15, and the positions of the baffles 24 and the holes 23 are matched. Each baffle 24 is connected to the fixed block 15 by a spring 25. A group of fixing rods 26 are movably connected to the top of each baffle 24, and the fixing rods 26 are fixedly connected to the bottom of the movable cover 16. Therefore, when the movable cover 16 is closed, the baffles 24 can be squeezed by the fixing rods 26, so that the baffles 24 move downward to squeeze the springs 25, so that the holes 23 are not blocked, so that cold air can enter the fixed block 15 through the holes 23. When the movable cover 16 is opened, the fixing rods 26 can be driven to rotate synchronously, so that the baffles 24 are not squeezed by the fixing rods 26, so that the holes 23 can be reset by the springs 25 to block the holes. Through this device, when the movable cover 16 is opened, cold air cannot enter the fixed block 15, thereby avoiding waste of cold air.

[0034] At the same time, the connecting pipe 10 is set to be a bellows material to avoid affecting the movement of the movable block 7. At the same time, the baffle 24 is set to an "I"-shaped structure to limit the movement range of the baffle 24 and prevent it from sliding out or falling from the fixed block 15.

[0035] The air pump 11 and the refrigeration device 22 in this embodiment are prior arts, wherein the air pump 11 changes the internal pressure through the movement of a piston, a rotor, a diaphragm, etc. to achieve gas transportation; and the refrigeration device 22 is based on the phase change cycle of the refrigerant and achieves a refrigeration effect through four processes of compression, condensation, expansion and evaporation, and is a structure known to technicians in this field.

[0036] Although an embodiment of the utility model has been shown and described, this specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
