Description

Technical Field

[0001] This invention relates to the field of vulcanization equipment technology, and specifically to a vulcanization device for rubber product manufacturing. Background Technology

[0002] In the large-scale production of rubber products, vulcanization is a key process that determines product performance. Multi-mold molds, which can simultaneously vulcanize and mold multiple products, have become core equipment for improving production efficiency. To reduce the subsequent separation process of multiple molded products after vulcanization, existing technologies often integrate cutters into the multi-mold mold. The cutters are used to directly divide the cured finished products after vulcanization, thereby shortening the production process and reducing manual intervention costs.

[0003] However, current multi-mold vulcanization molds with integrated cutters have certain drawbacks in practical applications. Rubber vulcanization requires a high-temperature environment to ensure full cross-linking of rubber molecules and vulcanizing agents. After vulcanization, the mold needs to be cooled to the rubber curing temperature range for rapid demolding. The cutter integrated inside the mold must undergo the high-temperature vulcanization and low-temperature curing cycle throughout the entire process. Frequent hot and cold cycles can cause thermal stress fatigue within the cutter material, leading to damage such as blade breakage. This not only necessitates frequent cutter replacements to ensure separation efficiency but also increases equipment maintenance costs and production downtime. Summary of the Invention

[0004] This invention provides a vulcanizing device for rubber product manufacturing, aiming to solve the problem of low blade life caused by frequent hot and cold alternation of the cutting blade in multi-molds in related technologies.

[0005] The present invention provides a vulcanizing apparatus for producing rubber products, comprising a main body and an upper mold and a lower mold disposed inside the main body. The lower mold is capable of vertical sliding relative to the main body, and a partition chamber is slidably assembled inside the upper mold, capable of vertical sliding relative to the upper mold, for separating the mold cavity. A crossbeam is provided on the inner side of the main body, and the crossbeam is located above the upper mold. A rotating rod is rotatably connected to the crossbeam, and the rotating rod is located above the crossbeam. The crossbeam and the rotating rod can slide vertically relative to the main body during the sliding of the lower mold, and the rotating rod can rotate as the crossbeam slides. A hook plate is installed above the compartment and a hook rod is installed below the rotating rod. The hook rod can slide vertically back and forth as the rotating rod rotates, and the hook plate can drive the compartment to slide vertically back and forth through the sliding of the hook rod. A reciprocating column is installed through the cross frame, and the reciprocating column can slide vertically relative to the cross frame. A reciprocating frame is fixedly connected to the top of the reciprocating column, and a rotating rod is inserted inside the reciprocating frame. A spring is installed between the reciprocating frame and the cross frame, and a hook rod is fixedly connected to the bottom of the reciprocating column. Both ends of the rotating rod are fixedly connected to gears, and the middle of the rotating rod is fixedly connected to a cam. The cam is located inside the reciprocating frame. Two toothed rods are fixedly connected to the top inner wall of the main body, and the two toothed rods mesh with two gears respectively.

[0006] Preferably, a telescopic column is fixedly connected to the top of the compartment, the telescopic column slides through the inside of the upper mold and extends to the top of the upper mold and is fixedly connected to the hook plate, and a spring is provided between the hook plate and the upper mold.

[0007] Preferably, the upper mold has a cavity inside, the partition chamber is slidably connected inside the cavity, the top of the lower mold has a partition groove adapted to the partition chamber, and the outer sides of the upper mold and the lower mold are respectively fixedly connected to mold frame one and mold frame two.

[0008] Preferably, connecting frames are fixedly connected to both sides of the cross frame, and guide rods are fixedly connected to the top inner wall of the main body, with the guide rods passing through the cross frame.

[0009] Preferably, a hydraulic cylinder is fixedly installed at the bottom of the inner side of the main body, and a top plate and a guide plate are fixedly connected to the telescopic end of the hydraulic cylinder, with the guide plate located below the top plate and fixedly connected to the connecting frame.

[0010] Preferably, a cylinder is provided on the rear side of the main body, and a push plate is fixedly connected to the telescopic end of the cylinder. A rotating shaft and a guide post are provided on the side of the push plate away from the cylinder, and the rotating shaft is located above the guide post. Mold frame one is rotatably mounted on the rotating shaft, and mold frame two is slidably mounted on the guide post.

[0011] Preferably, the inner side of the main body is provided with straight groove rods and corner groove rods, with two of each type, arranged symmetrically on the left and right. The corner groove rods are located above the straight groove rods. Both the straight groove rods and the corner groove rods are fixedly connected to the inside of the main body and extend to the outside of the main body. The inside of the straight groove rod is connected to several straight-out wheels, which are rotatably mounted on both sides of the mold frame two. The inside of the corner groove rod is connected to two corner wheels, which are rotatably mounted on both sides of the mold frame one.

[0012] Preferably, the straight groove rod is provided with a plurality of lifting grooves corresponding to the straight output wheel, and an elastic pressure plate is provided inside the lifting groove.

[0013] The beneficial effects of this invention are: 1. When using multi-molds that require vulcanizing multiple rubber products, this device can divide the mold cavity into independent units through the partition chamber before the rubber is vulcanized, preventing the rubber raw material from flowing into the cavity after melting, eliminating the need for subsequent cutting procedures. After vulcanization, during the mold opening process, the vibrating partition chamber can detach the cured rubber product from its chamber wall, eliminating the need for manual cleaning of adhering materials. This ensures production continuity and also saves the trouble of subsequent material unloading difficulties.

[0014] Second, when the lower mold rises, the partition chamber also vibrates, which can automatically fill the corner areas of the cavity with raw materials (rubber raw materials and vulcanizing agents), avoiding problems such as local material shortage and uneven wall thickness in the finished product after vulcanization due to uneven accumulation of raw materials.

[0031] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] like Figures 1 to 15 As shown, a vulcanizing apparatus for rubber product manufacturing according to the present invention includes: a main body 10, a pushing assembly 20, a pushing assembly 30, an upper mold 40, a lower mold 50, a separating assembly 42, a vibration assembly 60, and a unfolding assembly 70. The upper mold 40 and the lower mold 50 are disposed inside the main body 10. The lower mold 50 can receive the rubber raw material to be vulcanized. The separating assembly 42 is disposed on the upper mold 40 and can divide the cavity between the upper mold 40 and the lower mold 50 into multiple mold cavities. The pushing assembly 20 is located at the bottom inner side of the main body 10 and is used to push the lower mold 50 onto the upper mold 40 to vulcanize the rubber raw material. For vulcanization, the pushing component 30 is located at the rear of the main body 10, which can push the upper mold 40 and the lower mold 50 to the outside of the main body 10 for easy loading and unloading. The vibration component 60 is located between the upper mold 40 and the top of the main body 10, which can work with the pushing component 20 to make the separating component 42 vibrate when the upper mold 40 and the lower mold 50 are separated, so as to prevent the vulcanized raw material from sticking to the separating component 42. The unfolding component 70 is located at the front of the main body 10, which can tilt the upper mold 40 when the upper mold 40 and the lower mold 50 are pushed to the outside of the main body 10 for easy loading and unloading.

[0033] like Figures 1 to 2 As shown, the front and rear sides of the main body 10 are respectively fixedly connected to a front support 11 and a rear support 12 to support the unfolding component 70 and the pushing component 30, thereby improving structural stability.

[0034] like Figure 1, Figure 2 as well as Figure 9 As shown, the push assembly 20 includes a hydraulic cylinder 201, a top plate 202, and a guide plate 203. The hydraulic cylinder 201 is fixedly installed at the bottom of the inner side of the main body 10. The top plate 202 and the guide plate 203 are both fixedly connected to the telescopic end of the hydraulic cylinder 201, and the guide plate 203 is located below the top plate 202. When the hydraulic cylinder 201 is activated, it can drive the top plate 202 to rise or fall, so that the lower mold 50 rises or falls and moves closer to or away from the upper mold 40 to vulcanize and demold the rubber product. The guide plate 203 is slidably connected to the inner wall of the main body 10, which can ensure that the movement direction of the top plate 202 and the lower mold 50 is vertically upward or downward.

[0035] like Figures 1 to 3 As shown, the pushing component 30 includes a cylinder 301 and a push plate 302. The cylinder 301 is fixedly mounted on the rear bracket 12, and the push plate 302 is fixedly connected to the telescopic end of the cylinder 301. A rotating shaft 3021 and a guide post 3022 are provided on the side of the push plate 302 away from the cylinder 301, and the rotating shaft 3021 is located above the guide post 3022. The upper mold 40 is rotatably mounted on the rotating shaft 3021, and the lower mold 50 is slidably mounted on the guide post 3022. It can slide on the guide post 3022 when the top plate 202 pushes. After the cylinder 301 is started, the push plate 302 is displaced, which can push the upper mold 40 and the lower mold 50 into the unfolding component 70 for unfolding, which facilitates subsequent loading and unloading. In addition, the guide post 3022 can guide and limit the lower mold 50 during the pushing process, avoid the lower mold 50 from shifting laterally, and ensure that the relative position of the upper mold 40 and the lower mold 50 is accurate after pushing, thus ensuring the vulcanization molding accuracy.

[0036] like Figure 1 , Figure 2 as well as Figures 4 to 8 As shown, the upper mold 40 has a cavity 401 inside for placing the separator component 42. A mold frame 41 is provided on the outside of the upper mold 40. The upper mold 40 is fixedly installed on the mold frame 41 and is rotatably assembled on the rotating shaft 3021 through the mold frame 41. Multiple forming punches are provided at the bottom of the upper mold 40, which can cooperate with the lower mold 50 to form a specific shape of rubber during vulcanization.

[0037] The separating component 42 includes a separating chamber 421, a telescopic column 422, a spring 423, and a hook plate 424. The separating chamber 421 is slidably connected to the inside of the upper mold 40 and can slide vertically relative to the upper mold 40, and can separate multiple forming punches. Multiple telescopic columns 422 are fixedly connected to the top of the separating chamber 421. The telescopic columns 422 slide through the inside of the upper mold 40 and extend to the top of the upper mold 40 and are fixedly connected to the hook plate 424. The spring 423 is disposed between the hook plate 424 and the upper mold 40. When the separating chamber 421 slides inside the upper mold 40, the telescopic column 422 synchronously drives the hook plate 424 to slide. The spring 423 is a tension spring, which can ensure that the separating chamber 421 is below the upper mold 40 when there is no external force, and can contact the lower mold 50 before the upper mold 40 when the lower mold 50 slides upward.

[0038] The top of the lower mold 50 is provided with a partition groove 501 that is adapted to the partition chamber 421, and the top of the lower mold 50 is provided with a forming cavity that corresponds one-to-one with the forming punch. The forming punch and the forming cavity form a forming cavity. The upper mold 40 and the lower mold 50 are also provided with a heating component, a cooling component, and an exhaust port (not shown). When the upper mold 40 and the lower mold 50 are close together, the rubber raw material and the vulcanizing agent are mixed and located between the forming punch and the forming cavity. After extrusion, the rubber raw material is melted by the heating component and solidified by the cooling component. The gas generated during the forming process is discharged through the exhaust port.

[0039] During the process of the lower mold 50 sliding to the upper mold 40, the partition chamber 421 contacts the partition groove 501 in advance, dividing the cavity between the lower mold 50 and the upper mold 40 into multiple cavities. During the subsequent upward movement of the lower mold 50, the partition chamber 421 can be pushed to slide upward, and the spring 423 is stretched. The elastic potential energy provided by the spring 423 can ensure that the partition chamber 421 is tightly attached to the partition groove 501, preventing the rubber material from melting and spreading to the adjacent molding cavity.

[0040] like Figure 1 , Figure 2 as well as Figures 9 to 11As shown, the vibration assembly 60 includes a crossbeam 601 and a rotating rod 602. The rotating rod 602 is rotatably mounted on the crossbeam 601 and is located above the crossbeam 601. The crossbeam 601 can slide vertically relative to the main body 10. A reciprocating column 6011 is provided through the crossbeam 601 and can slide vertically relative to the crossbeam 601. A reciprocating frame 6012 is fixedly connected to the top of the reciprocating column 6011. The rotating rod 602 passes through the interior of the reciprocating frame 6012. The reciprocating frame 6012 and the crossbeam 6011 are connected. A second spring 6013 is provided between the two parts. A hook rod 6014 is fixedly connected to the bottom of the reciprocating column 6011. The hook rod 6014 is located below the crossbeam 601, and the end of the hook rod 6014 is provided with a hook. The hook is adapted to the edge of the hook plate 424. When the reciprocating column 6011 slides vertically back and forth, it can drive the hook plate 424 to slide up and down through the hook, so that the separator 421 will generate vertical vibration, and prevent the vulcanized rubber from sticking to the wall of the separator 421. The second spring 6013 is used to help the reciprocating column 6011 return to its original position.

[0041] Both ends of the rotating rod 602 are fixedly connected to gears 6021, and the middle of the rotating rod 602 is fixedly connected to a cam 6022. The cam 6022 is located inside the reciprocating frame 6012. Two racks 6023 are fixedly connected to the top inner wall of the main body 10, and the two racks 6023 mesh with the two gears 6021 respectively. The rotating rod 602 can slide vertically with the cross frame 601, causing the gears 6021 to roll on the surface of the racks 6023, thereby causing the rotating rod 602 and the cam 6022 fixedly connected to it to rotate. The cam 6022 can force the reciprocating frame 6012 to produce a vertical linear reciprocating motion, thereby causing the reciprocating column 6011 to slide vertically back and forth, so that the partition chamber 421 produces vertical vibration.

[0042] Connecting frames 61 are fixedly connected to both sides of the cross frame 601. The connecting frames 61 are fixedly connected to the guide plate 203 and can move with the guide plate 203 and drive the cross frame 601 to slide vertically. A guide rod 62 is fixedly connected to the top inner wall of the main body 10. The guide rod 62 passes through the cross frame 601 and can ensure that the cross frame 601 does not deflect when sliding vertically.

[0043] It should be noted that after the rubber vulcanization is completed, the mold needs to be opened, that is, the upper mold 40 and the lower mold 50 are separated. At this time, the hydraulic cylinder 201 drives the top plate 202 and the guide plate 203 to move down, and the lower mold 50 moves down accordingly. The partition chamber 421 also slides down due to the action of the spring 423. The cross frame 601 moves down synchronously with the guide plate 203, and the hook plate 424 generates vertical reciprocating sliding under the drive of the rotating rod 602, which in turn drives the partition chamber 421 to generate vertical reciprocating sliding. That is, during the process of the partition chamber 421 sliding down inside the upper mold 40, it will also generate a vertical reciprocating vibration, which prevents the vulcanized rubber from sticking to its chamber wall and reduces the processing difficulty of subsequent production stages. During the process of the lower mold 50 moving upward, the partition chamber 421 also generates vibration after contacting the partition groove 501. This can vibrate and level the mixture of rubber raw material and vulcanizing agent placed inside the molding cavity, filling the corner area of ​​the cavity, which is convenient for subsequent molding.

[0044] like Figure 1 , Figure 2 , Figure 14 as well as Figure 15 As shown, the unfolding assembly 70 includes two straight groove rods 701 and two corner groove rods 702. Both straight groove rods 701 and corner groove rods 702 are provided and arranged symmetrically on the left and right sides. The corner groove rod 702 is located above the straight groove rod 701. Both the straight groove rod 701 and the corner groove rod 702 are fixedly connected to the interior of the main body 10 and extend to the exterior of the main body 10, where they are fixedly connected to the front support 11. The corner groove rod 702 has a bend. Several straight-out wheels 7011 are rolled inside the straight groove rod 701, and the straight-out wheels 7011 are rotatably mounted on both sides of the mold frame 51. The mold frame 51 moves under the push of the push plate 302, and the straight-out wheels 7011 are in the groove of the straight groove rod 701. The internal rolling mechanism allows the lower mold 50 to slide smoothly out of the main body 10. The corner groove rod 702 has two corner wheels 7021 internally connected. The corner wheels 7021 are rotatably mounted on both sides of the mold frame 41. The mold frame 41 moves under the push of the push plate 302. The corner wheels 7021 roll in the groove of the corner groove rod 702 and pass through the bend, so that the upper mold 40 rotates upward to tilt during the process of sliding out of the main body 10, which facilitates loading and unloading. The bend angle is optimized to avoid collision with other parts when the upper mold 40 is tilted. At the same time, the tilt angle conforms to ergonomics, reducing the labor intensity of workers when loading and unloading materials and improving the safety and comfort of operation.

[0045] The straight groove rod 701 is provided with several lifting grooves 7012 corresponding to the straight wheel 7011. The lifting groove 7012 is provided with an elastic pressure plate 7013. When the top plate 202 pushes the lower mold 50 to slide upward, the straight wheel 7011 is lifted into the lifting groove 7012 to avoid the straight wheel 7011 interfering with the lifting of the lower mold 50. When the top plate 202 moves downward, the elastic pressure plate 7013 can exert pressure on the straight wheel 7011 through its own elasticity to ensure that the straight wheel 7011 can accurately fall back to the normal track of the straight groove rod 701 when the lower mold 50 descends.

[0046] Working principle: When the cylinder 301 is started, it drives the push plate 302 to push the upper mold 40 and the lower mold 50 to the outside of the main body 10. During the process, the straight wheel 7011 rolls in the straight groove rod 701 to make the lower mold 50 slide out smoothly. The corner wheel 7021 rolls in the corner groove rod 702 with a bend to make the upper mold 40 tilt. The operator can easily put the rubber raw material and vulcanizing agent mixture into the molding cavity of the lower mold 50. The pushing component 30 sends the upper mold 40 and the lower mold 50 back into the main body 10. The hydraulic cylinder 201 of the pushing component 20 is activated, driving the top plate 202 and the guide plate 203 to rise, so that the lower mold 50 moves upward and approaches the upper mold 40. During the upward movement of the lower mold 50, it first contacts the separating component 42 of the upper mold 40. The separating chamber 421 enters the separating groove 501 and divides the cavity into multiple mold cavities. Subsequently, the lower mold 50 continues to rise, pushing the separating chamber 421 to move upward and stretching the spring 423. The elastic force of the spring 423 makes the separating chamber 421 stick tightly to the separating groove 501 to prevent the raw material from flowing into the cavity after melting. At the same time, the forming punch of the upper mold 40 and the forming cavity of the lower mold 50 close to form a forming cavity. The heating components in the upper mold 40 and the lower mold 50 are activated to melt and vulcanize the raw material. The generated gas is discharged through the exhaust port. After vulcanization, the hydraulic cylinder 201 drives the top plate 202 and guide plate 203 to move down, and the lower mold 50 descends and separates from the upper mold 40. During this process, the connecting frame 61 drives the cross frame 601 of the vibration component 60 to move down synchronously. The downward movement of the cross frame 601 causes the gear 6021 of the rotating rod 602 to roll on the rack 6023. The rotating rod 602 and the cam 6022 rotate. The cam 6022 forces the reciprocating frame 6012 to drive the reciprocating column 6011 to slide vertically back and forth. The reciprocating column 6011 drives the hook plate 424 and the separator 421 to vibrate through the hook rod 6014, so as to prevent the vulcanized rubber from sticking to the separator 421. Similarly, during the upward movement of the lower mold 50, the separator 421 can vibrate and impact the lower mold 50, so that the raw material mixture is leveled in the molding cavity and automatically filled to the corner area of ​​the cavity. The pushing component 30 pushes the upper mold 40 and lower mold 50 to the outside of the main body 10 again, and the unfolding component 70 tilts the upper mold 40 so that the workers can take out the vulcanized rubber product and complete one production cycle.
