Description

Technical Field

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

[0002] Vulcanization is a very important process in the rubber industry. Through this process, rubber materials can obtain better physical and mechanical properties, such as strength, elasticity, and abrasion resistance.

[0003] The patent with publication number CN219788988U discloses a rubber molding vulcanizing machine. A fixed shaft is provided on the inner side of the silicone mold, and a groove is provided on the inner side of the fixed shaft. An upper plate is provided on the top of the silicone mold, and a groove is movably connected to the outer side of the upper plate. A washer is movably connected to the top of the upper plate, and a connecting column is movably connected to the end of the washer away from the upper plate. One end of the connecting column is movably connected to the bottom of the extrusion plate. A base plate is provided at the bottom of the silicone mold, and a groove is movably connected to the outer side of the base plate. When the flat vulcanizing machine processes rubber, after the product in the mold is formed, it is easily removed from the mold via the upper plate and base plate connected on both sides of the silicone mold, preventing damage to the finished product.

[0004] However, the vulcanizing machine mentioned above still has the following problems in actual use:

[0005] During rubber vulcanization, a series of harmful gases are released. These gases mainly originate from byproducts of the vulcanization reaction, the thermal decomposition of rubber materials, and the volatilization of compounding agents. If these waste gases are emitted directly without treatment, they will not only pollute the environment but may also pose a threat to human health. However, most vulcanization equipment currently on the market lacks effective waste gas absorption and treatment capabilities, which brings potential risks to the operating environment and personnel safety. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a rubber primary processing vulcanization device that can remove gas after the upper and lower molds are separated, thereby reducing the impact on the environment and personnel.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rubber primary processing vulcanization device, comprising a base with four pillars, a hydraulic rod mounted on the base, a lifting plate mounted on the output end of the hydraulic rod, and a top plate mounted on the upper end of the base pillars. A lower mold and an upper mold are fixedly connected to the adjacent side of the lifting plate and the top plate, respectively. Four adjusting components are connected to the side of the top plate near the lifting plate. The four adjusting components are arranged in pairs. The lower ends of the two sets of adjusting components are respectively connected to two suction boxes. The cross-section of the two suction boxes is fan-shaped, and the wider end of the fan-shaped section faces the space between the lower mold and the upper mold.

[0008] Furthermore, the adjustment assembly includes a threaded rod and a support block. The upper end of the threaded rod is fixedly connected to the bottom surface of the top plate, the lower end of the threaded rod passes through one end of the support block and is slidably connected to the support block, and the other end of the support block is fixedly connected to the outer wall of the air intake box.

[0009] Furthermore, an anti-detachment plate is fixedly connected to one end of the threaded rod that passes through the support block. The diameter of the anti-detachment plate is larger than the diameter of the through hole of the threaded rod on the support block.

[0010] Furthermore, a spring is fixedly connected to the upper surface of the support block, and the other end of the spring is fixedly connected to the bottom surface of the top plate.

[0011] Furthermore, a nut is threaded onto the outer wall of the threaded rod, and the nut is located between the support block and the anti-detachment plate.

[0012] Furthermore, a shim assembly is connected to the side of the lifting plate near the top plate, and the upper end of the shim assembly is connected to the bottom surface of the two air intake boxes.

[0013] Furthermore, several grooves are provided on the side of the lifting plate near the top plate, and the lower end of the shim assembly is located in the grooves.

[0014] Furthermore, the elevation component includes several top blocks, the lower ends of which are slidably connected to the slide groove. The top blocks are divided into two groups, and the upper ends of the two groups of top blocks abut against the bottom surfaces of the outer walls of the two air intake boxes, respectively.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This rubber primary processing vulcanization device, by setting fan-shaped air suction boxes on both sides of the upper and lower molds, can promptly suck away the vulcanization waste gas at the moment of mold separation and guide it to the external filtration equipment, significantly reducing the impact of harmful gases on the environment and operators;

[0017] 2. In this type of rubber primary processing vulcanization device, the adjusting component, through the cooperation of threaded rod, support block and spring, enables the air suction box to rise and fall synchronously with the lifting plate, always maintaining the optimal air suction position with the mold, and ensuring stable waste gas absorption efficiency.

[0023] 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.

[0024] Please see Figures 1-4 A rubber primary processing vulcanization device includes a base 1 with four pillars, a hydraulic rod 12 mounted on the base 1, a lifting plate 2 mounted on the output end of the hydraulic rod 12, and a top plate 13 mounted on the upper end of the pillars of the base 1. A lower mold 3 and an upper mold 7 are fixedly connected to the adjacent side of the lifting plate 2 and the top plate 13, respectively. Four adjustment components are connected to the side of the top plate 13 near the lifting plate 2. The four adjustment components are in pairs. The lower ends of the two sets of adjustment components are respectively connected to two suction boxes 4. The cross-section of the two suction boxes 4 is fan-shaped, and the wider end of the fan-shaped section faces the space between the lower mold 3 and the upper mold 7.

[0025] like Figures 1 to 4 As shown, when using the rubber primary processing vulcanization device of this utility model, the rubber raw material is first placed on the lower mold 3 on the lifting plate 2 (before this, the lower mold 3 and the upper mold 7 need to be preheated). Then, the lifting plate 2, the lower mold 3 and the rubber raw material are pushed up by the hydraulic rod 12. After the lower mold 3 and the upper mold 7 overlap, the rubber raw material can be made into the required shape in the mold by heating the lower mold 3 and the upper mold 7.

[0026] After the set time is reached, the hydraulic rod 12 descends, taking the lower mold 3 and the finished rubber product with it. At this time, the lower mold 3 and the upper mold 7 separate. As they separate, the odor can escape from the separation point. However, because there are two air suction boxes 4 on both sides of the lower mold 3 and the upper mold 7, these odors can be sucked away and directed to the external flue gas filtration equipment (this is an existing mature technology and will not be described in detail here), thereby reducing the impact on the environment and personnel.

[0027] In addition, because an adjustment component is provided between the lower mold 3 and the upper mold 7, the two suction boxes 4 can rise and fall together with the lifting plate 2 (i.e., the lower mold 3), thereby ensuring the position of the adjustment component.

[0028] It should be noted that the base 1 with four pillars, hydraulic rod 12, lifting plate 2, top plate 13, lower mold 3 and upper mold 7 mentioned above are all mature technologies in existing rubber vulcanizing machines. Their positional relationship, connection relationship and working principle will not be described in detail here. In addition, in this utility model, only the structure of the disclosed patent is partially improved. Structures not mentioned in the disclosed patent, such as the base 1 and hydraulic rod 12 mentioned above, are not modified in any way and retain their original functions and effects.

[0029] As a preferred embodiment of this utility model, the adjustment component includes a threaded rod 5 and a support block 9. The upper end of the threaded rod 5 is fixedly connected to the bottom surface of the top plate 13, the lower end of the threaded rod 5 passes through one end of the support block 9 and is slidably connected to the support block 9, and the other end of the support block 9 is fixedly connected to the outer wall of the air intake box 4.

[0030] More specifically, when the lifting plate 2 rises, it will push the support block 9 to rise together, and the rise of the support block 9 will push the suction box 4 to rise together, thereby ensuring the relative position of the suction box 4 and the lower mold 3.

[0031] In addition, the lower end of the threaded rod 5 passes through the perforation on the lifting plate 2, and will not obstruct the normal movement of the lifting plate 2.

[0032] As a preferred embodiment of this utility model, an anti-detachment piece 11 is fixedly connected to one end of the threaded rod 5 that passes through the support block 9. The diameter of the anti-detachment piece 11 is larger than the diameter of the through hole of the threaded rod 5 on the support block 9.

[0033] More specifically, by setting the anti-detachment plate 11, the support block 9 can be prevented from falling off the lower end of the threaded rod 5.

[0034] As a preferred embodiment of this utility model, a spring 6 is fixedly connected to the upper surface of the support block 9, and the other end of the spring 6 is fixedly connected to the bottom surface of the top plate 13.

[0035] More specifically, by setting spring 6, when the lifting plate 2 and the lower mold 3 descend, spring 6 can provide an additional thrust to the support block 9 and the suction box 4, ensuring that the suction box 4 can descend and will not stop on the threaded rod 5.

[0036] As a preferred embodiment of this utility model, the outer wall of the threaded rod 5 is threaded with a nut 10, which is located between the support block 9 and the anti-detachment plate 11.

[0037] More specifically, by setting the nut 10, the initial height of the support block 9 when it stops can be limited, thereby adapting to the height of the lower mold 3 at different heights.

[0038] As a preferred embodiment of this utility model, the lifting plate 2 is connected to a shim assembly on the side near the top plate 13, and the upper end of the shim assembly is connected to the bottom surface of the two air intake boxes 4.

[0039] More specifically, by setting up a shim assembly, a support for the air intake box 4 can be added to the lifting plate 2, thereby improving the stability of the air intake box 4.

[0040] As a preferred embodiment of this utility model, the lifting plate 2 has several sliding grooves 201 on the side near the top plate 13, and the lower end of the raising component is located in the sliding grooves 201.

[0041] More specifically, by setting the slide 201, different height shims can be replaced according to the different heights of the lower mold 3.

[0042] As a preferred embodiment of the present invention, the elevation component includes a plurality of top blocks 8, the lower ends of which are slidably connected to the sliding groove 201. The plurality of top blocks 8 are divided into two groups, and the upper ends of the two groups of top blocks 8 respectively abut against the bottom surface of the outer wall of the two air intake boxes 4.

[0043] More specifically, when starting to use the device, simply insert several top blocks 8 through the slide 201, ensuring that the top blocks 8 are located below the air intake box 4;

[0044] It should be noted that the top block 8 can be stopped in the slide groove 201 by friction, or it can be restricted to the slide groove 201 by bolts or clamps, etc. The specific method is not limited.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
