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

[0002] The rubber strip vulcanization processing equipment is used for the vulcanization treatment of rubber or synthetic materials. Vulcanization refers to the reaction of rubber with sulfur to enhance its physical properties and elasticity. It involves heating, pressurizing and adding sulfur or other crosslinking agents to make raw rubber undergo a chemical reaction to form a network structure, thereby obtaining shaping, reinforcement and aging resistance properties.

[0003] A rubber strip vulcanization processing device, such as the one disclosed in announcement number CN222819363U, includes a base and a support platform mounted on the base. A vulcanizing machine body is mounted on the support platform. A guide column is located inside the vulcanizing machine body. A lower mold mounting plate is located on the bottom wall of the vulcanizing machine body. An upper mold mounting plate is slidably mounted on the guide column. An electric cylinder is located at the top of the vulcanizing machine body. The free end of the electric cylinder is connected to the upper mold mounting plate. An upper mold is located at the bottom of the upper mold mounting plate. A lower mold is mounted on the upper mold mounting plate. An auxiliary feeding structure is also provided on the base. This utility model relates to the field of rubber strip vulcanization technology, specifically providing a rubber strip vulcanization processing device.

[0004] The aforementioned patent proposes that the rubber strip can be ejected by the cooperation of an electric telescopic rod, a lifting plate, and an ejector plate, which facilitates the ejection of the vulcanized rubber strip from the lower mold. However, during the use of the rubber strip vulcanization processing device, since the rubber strip is vulcanized inside the vulcanizing machine, the rubber strip is taken out by the grippers after vulcanization. The vulcanized rubber strip is not easy to separate from the mold groove, and direct ejection can easily cause damage to the side wall of the rubber strip, affecting the appearance of the rubber strip. Summary of the Invention

[0005] The purpose of this utility model is to provide a rubber strip vulcanization processing device to solve the problem mentioned in the background art that the vulcanized rubber strip is not easy to separate from the mold groove, and direct ejection can easily cause damage to the side wall of the rubber strip, affecting the appearance of the rubber strip.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rubber strip vulcanization processing device, comprising a base and a vulcanizing machine body installed on the upper end of the base, a door installed at the front end of the vulcanizing machine body, the vulcanizing machine body comprising an electric push rod A and an upper mold base connected to the telescopic end of the electric push rod A, the upper mold base being located inside the vulcanizing machine body, a lower mold base being installed on the inner bottom wall of the vulcanizing machine body, a mold groove being formed on the surface of the lower mold base, a forming block being installed at the lower end of the upper mold base, the forming block being positioned opposite the mold groove, a cavity being formed inside the vulcanizing machine body, a demolding structure being installed in the cavity, and an airflow auxiliary component being embedded inside the lower mold base, the airflow auxiliary component being used to blow airflow onto the edge of the rubber strip in the mold groove, and cooperating with the demolding structure to complete demolding.

[0007] Preferably, the inner wall of the mold groove is uniformly coated with a Teflon coating, which can serve as a non-stick coating.

[0008] Preferably, the demolding structure includes an electric push rod B and a connecting plate connected to the telescopic end of the electric push rod B. Several push rods are evenly distributed on the upper end of the connecting plate. An ejector plate is installed on the upper end of the push rod. A collar is installed on the side of the ejector plate near the push rod. The collar is located on the outside of the push rod and is fixed by bolts.

[0009] Preferably, the airflow auxiliary component includes a pump body, an intake pipe, and an exhaust pipe. The pump body is located outside the vulcanizing machine body. The two ends of the pump body are connected to the intake pipe and the exhaust pipe, respectively. A filter cover for filtration is fitted on the outside of one end of the intake pipe. One end of the exhaust pipe is connected to a diverter pipe. The end of the diverter pipe away from the exhaust pipe is connected to an air jet pipe, which is embedded in the lower mold base. Several nozzles are evenly distributed on the air jet pipe. When the pump body is started, the intake pipe draws in air, and the gas flows through the exhaust pipe, the diverter pipe, and the air jet pipe before being ejected from the nozzles.

[0010] Preferably, a flow equalization plate is embedded in the inner wall of the mold groove, and the flow equalization plate is located on one side of the nozzle, so that the airflow can be evenly distributed after passing through the flow equalization plate.

[0011] Preferably, a slide rail is fixedly installed on the outer wall of the vulcanizing machine body, and a side door panel is slidably connected inside the slide rail. After the side door panel is pulled out from the slide rail, the rubber strip can be removed for cooling.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. Through the set base, vulcanizing machine body and box door, the rubber strip is vulcanized in the vulcanizing machine body. At the same time, the airflow auxiliary component can blow airflow on the edge of the rubber strip in the mold groove to reduce the adhesion between the rubber strip and the mold groove, and complete the demolding in conjunction with the demolding structure, which is conducive to demolding of the rubber strip. The airflow assistance can effectively reduce scratches on the rubber strip.

[0013] 2. Through the set ejector plate, collar and mold groove, the ejector plate moves up and down in the mold groove to push out the rubber strip. The set Teflon coating effectively reduces the friction to prevent the rubber strip from sticking in the mold groove. In addition, the ejector plate is installed on the top plate in a detachable manner, so it can be replaced in time when wear occurs. Attached Figure Description

[0016] 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.

[0017] Example 1: Please refer to Figures 1-4 A rubber strip vulcanization processing device includes a base 1, a vulcanizing machine body 2, and a door 3. The vulcanizing machine body 2 is located at the upper end of the base 1 and is used to vulcanize the rubber strip. The door 3 is located at the front end of the vulcanizing machine body 2 (the vulcanizing machine body 2 is prior art and does not need to be described in detail).

[0018] The vulcanizing machine body 2 includes an electric push rod A21 and an upper mold base 22 connected to the telescopic end of the electric push rod A21. The upper mold base 22 is located inside the vulcanizing machine body 2. A lower mold base 23 is installed on the inner bottom wall of the vulcanizing machine body 2. A mold groove 24 is opened on the surface of the lower mold base 23. A forming block 25 is installed at the lower end of the upper mold base 22. The forming block 25 is positioned opposite to the mold groove 24. A cavity 27 is opened inside the vulcanizing machine body 2. A demolding structure 28 is installed in the cavity 27. An airflow auxiliary component 26 is embedded inside the lower mold base 23. The airflow auxiliary component 26 is used to blow airflow onto the edge of the rubber strip in the mold groove 24 to reduce the adhesion between the rubber strip and the mold groove 24, and to complete demolding in conjunction with the demolding structure 28.

[0019] The demolding structure 28 includes an electric push rod B281 and a connecting plate 282 connected to the telescopic end of the electric push rod B281. Several push rods 283 are evenly distributed on the upper end of the connecting plate 282. An ejector plate 284 is installed on the upper end of the push rods 283. Both the electric push rod A21 and the electric push rod B281 are turned on and off by a switching power supply. When the electric push rod B281 is started, it can push the connecting plate 282 to move upward. At this time, the push rods 283 push the ejector plate 284 to move, which can push the rubber strip out of the mold groove 24.

[0020] The airflow auxiliary component 26 includes a pump body 261, an air intake pipe 262, and an exhaust pipe 263. The pump body 261 is located outside the vulcanizing machine body 2. The two ends of the pump body 261 are connected to the air intake pipe 262 and the exhaust pipe 263, respectively. A filter cover 267 for filtration is fitted on the outer side of one end of the air intake pipe 262. One end of the exhaust pipe 263 is connected to a diverter pipe 264. The end of the diverter pipe 264 away from the exhaust pipe 263 is connected to an air jet pipe 265, which is embedded in the lower mold base 23. Several nozzles 266 are evenly distributed on the air jet pipe 265. When the pump body 261 is started, the air intake pipe 262 draws in air. The gas flows through the exhaust pipe 263, the diverter pipe 264, and the air jet pipe 265 and is then ejected from the nozzles 266. The airflow can blow the rubber strip, which can help separate the rubber strip from the mold groove 24.

[0021] A flow equalization plate 268 is embedded in the inner wall of the mold groove 24. The flow equalization plate 268 is located on one side of the nozzle 266. After the airflow passes through the flow equalization plate 268, it can be evenly distributed, reducing the impact on the surface of the rubber strip.

[0022] A slide rail 4 is fixedly installed on the outer wall of the vulcanizing machine body 2. A side door panel 5 is slidably connected inside the slide rail 4. After the side door panel 5 is pulled out from the slide rail 4, the rubber strip of the ejector mold groove 24 can be taken out for cooling.

[0023] In this embodiment: the rubber strip is vulcanized in the mold groove 24 and formed in conjunction with the electric push rod A21, the upper mold base 22 and the molding block 25. When it is necessary to remove the rubber strip, the pump body 261 is started and the suction pipe 262 sucks in air. The filter cover 267 filters the dust. At this time, the gas flows through the exhaust pipe 263, the diversion pipe 264 and the jet pipe 265 and is sprayed out from the nozzle 266. The airflow can blow the rubber strip and, in conjunction with the flow equalization plate 268, can evenly distribute the airflow, reduce the impact on the surface of the rubber strip, and help the rubber strip separate from the mold groove 24. Then, the electric push rod B281 is started, which can push the connecting plate 282 to move upward. At this time, the ejector rod 283 pushes the ejector plate 284 to move, which can push the rubber strip out of the mold groove 24, which is conducive to demolding of the rubber strip. The airflow assistance can effectively reduce scratches on the rubber strip.

[0024] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 3 The inner wall of the mold groove 24 is uniformly coated with a Teflon coating 241, which serves to prevent sticking.

[0025] A collar 285 is installed on the side of the ejector plate 284 near the ejector rod 283. The collar 285 is located on the outside of the ejector rod 283 and is fixed with bolts, so that the ejector plate 284 can be fixed on the ejector rod 283.

[0026] In this embodiment: the adhesive strip is located inside the mold groove 24 and can contact the Teflon coating 241, effectively reducing friction to prevent the adhesive strip from adhering to the mold groove 24, which facilitates the ejection of the adhesive strip. Furthermore, the ejector plate 284 can be fixed to the ejector rod 283 by the cooperation of the collar 285 and bolts, which enables the ejector plate 284 to be disassembled and assembled.
