Description

Technical Field

[0001] This utility model relates to the field of rubber shoe production technology, specifically to a molding and vulcanization device for molded rubber shoes. Background Technology

[0002] The manufacture of rubber shoes typically involves making the sole and upper separately. Currently, the most common method for manufacturing rubber soles is compression molding and vulcanization, followed by assembling the semi-finished rubber sole with the semi-finished upper. The rubber sole undergoes a rubber refining process, during which vulcanizing agents and other chemical raw materials are added. The refined rubber sheets are then cut into strips and placed in molding equipment for vulcanization and shaping to form the shoe sole. After vulcanization, a second vulcanization process using hot air further cross-links the rubber molecules, improving its physical properties.

[0003] Chinese patent CN219583355U discloses a molding and vulcanization device for molded rubber shoes. This technical solution uses a side mold to fix the sole, and after the top mold moves upward a certain distance, a cooling mechanism cools the sole to promote demolding. When the left plate is driven downward by a moving mechanism, it presses against both the top and side molds. Furthermore, when the pressure plate moves upward, it allows for relative displacement between the top and side molds, facilitating the demolding of the top mold. An inverted "L"-shaped groove is provided in the side mold to limit the placement of the rubber shoe. This facilitates the demolding of the top mold and the cooling of the sole, while also allowing the left and right bottom molds to move left and right for demolding, further improving the overall demolding process of the sole.

[0004] However, the molding and vulcanizing device for this type of molded rubber shoe does not have a secondary hot vulcanizing function. This means that after the material is discharged, the device still needs to be put into a hot air mechanism for secondary vulcanization, which reduces the production efficiency of rubber shoes and is not conducive to the production of rubber shoes. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a molding and vulcanizing device for molded rubber shoes, which solves the problem that molding and vulcanizing devices for molded rubber shoes do not have a secondary hot air vulcanizing function, which means that after the material is discharged, the device still needs to be put into a hot air mechanism for secondary vulcanization.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a molding and vulcanizing device for molded rubber shoes, including a base plate, a first support rod fixedly connected to the upper surface of the base plate, a worktable fixedly connected to the top of the first support rod, and lower templates that move horizontally at both ends of the upper surface of the worktable, and a material discharge port opened on the worktable;

[0007] A transmission box is fixedly connected to one end of the lower surface of the workbench, and a transmission rod is rotatably provided on the other side of the transmission box. A receiving box is fixedly connected to the other end of the transmission rod. A diversion cavity communicating with an external hot air device is opened inside the receiving box, and several exhaust ports communicating with the diversion cavity are opened on the inner wall of the receiving box.

[0008] Furthermore, a motor is fixedly connected to the inner cavity of the transmission box, and a drive gear is fixedly connected to the output shaft of the motor. One end of the transmission rod extends rotatably into the inner cavity of the transmission box and is fixedly connected to a driven gear that meshes with the drive gear.

[0009] Furthermore, a connecting pipe is rotatably connected to the other side of the receiving box, and the connecting pipe is coaxial with the transmission rod.

[0010] Furthermore, a first protective shell is fixedly connected to both ends of the upper surface of the workbench. A first electric telescopic rod is provided inside the first protective shell. The inner end of the first electric telescopic rod extends movably to the outside of the first protective shell and is fixedly connected to the side wall of the lower template at the same end.

[0011] Furthermore, a plurality of second support rods are fixedly connected to the upper surface of the workbench, a top plate is fixedly connected to the top of the second support rods, a second protective shell is fixedly connected to the upper surface of the top plate, a second electric telescopic rod is fixedly connected inside the second protective shell, and the bottom end of the second electric telescopic rod extends movably to the bottom of the top plate and is fixedly connected to an upper mold base.

[0012] Furthermore, a receiving box located below the discharge port is placed on the upper surface of the base plate.

[0013] Furthermore, the plurality of exhaust ports are evenly spaced and distributed along the inner wall of the receiving box.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: after the rubber shoe vulcanization is completed, the two lower molds move away from each other, and the rubber shoe can be discharged through the discharge port, completing the automatic discharge of the rubber shoe. After discharge, the rubber shoe falls into the inside of the receiving box. After the external hot air equipment injects hot air into the distribution chamber, the hot air is distributed through multiple exhaust ports and discharged into the inside of the receiving box. This allows for a secondary vulcanization treatment of the rubber shoe inside the receiving box, further crosslinking the rubber molecules, improving the physical properties of the rubber shoe, increasing the functionality of the device, reducing the production steps of the rubber shoe, improving the production and processing efficiency of the rubber shoe, and benefiting the use of the rubber shoe production work.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a molding and vulcanizing device for molded rubber shoes, including a base plate 1, a first support rod 2 fixedly connected to the upper surface of the base plate 1, a workbench 3 fixedly connected to the top of the first support rod 2, and lower templates 8 that move horizontally at both ends of the upper surface of the workbench 3. The workbench 3 has a discharge port 22, and the two lower templates 8 can be spliced ​​together to form a complete lower mold base.

[0022] A transmission box 12 is fixedly connected to one end of the lower surface of the workbench 3, and a transmission rod 15 is rotatably arranged on the other side of the transmission box 12. A receiving box 17 is fixedly connected to the other end of the transmission rod 15.

[0023] The receiving box 17 has a diversion cavity 18 that communicates with an external hot air device inside, and the inner wall of the receiving box 17 has a number of exhaust ports 19 that communicate with the diversion cavity 18.

[0024] After the rubber shoe is vulcanized, the two lower mold plates 8 move away from each other, and the rubber shoe can be discharged through the discharge port 22, completing the automatic discharge of the rubber shoe.

[0025] After being unloaded, the rubber shoes fall into the receiving box 17. After hot air is injected into the diversion chamber 18 by an external hot air device, the hot air is diverted through multiple exhaust ports 19 and discharged into the receiving box 17, thereby enabling the rubber shoes inside the receiving box 17 to undergo secondary vulcanization treatment.

[0026] Further cross-linking of rubber molecules enhances the physical properties of rubber shoes, increases the functionality of the equipment, reduces the production steps of rubber shoes, improves the production and processing efficiency of rubber shoes, and facilitates the use of rubber shoes in production.

[0027] A motor 13 is fixedly connected to the inner cavity of the transmission box 12. The output shaft of the motor 13 is fixedly connected to the drive gear 14. One end of the transmission rod 15 extends rotatably into the inner cavity of the transmission box 12 and is fixedly connected to the driven gear 16 that meshes with the drive gear 14.

[0028] After the motor 13 drives the drive gear 14 to rotate, it can drive the transmission rod 15 to rotate through the driven gear 16, thereby driving the receiving box 17 to flip, which facilitates the automatic unloading of the rubber shoes after secondary vulcanization.

[0029] The other side of the receiving box 17 is rotatably connected to a connecting pipe 20. The connecting pipe 20 is coaxial with the transmission rod 15. The connecting pipe 20 facilitates the connection between the external hot air equipment and the inner cavity of the diversion chamber 18.

[0030] Both ends of the upper surface of the workbench 3 are fixedly connected to a first protective shell 6. The first protective shell 6 is provided with a first electric telescopic rod 7 inside. The inner end of the first electric telescopic rod 7 extends to the outside of the first protective shell 6 and is fixedly connected to the side wall of the lower template 8 at the same end.

[0031] Several second support rods 4 are fixedly connected to the upper surface of the workbench 3. A top plate 5 is fixedly connected to the top of the second support rods 4. A second protective shell 9 is fixedly connected to the upper surface of the top plate 5. A second electric telescopic rod 10 is fixedly connected inside the second protective shell 9. The bottom end of the second electric telescopic rod 10 extends movably to the bottom of the top plate 5 and is fixedly connected to the upper mold base 11.

[0032] A receiving box 21 located below the discharge port 22 is placed on the upper surface of the base plate 1, and multiple exhaust ports 19 are evenly distributed and spaced along the inner wall of the receiving box 17.

[0033] During operation, after the rubber shoe is vulcanized, the two lower mold plates 8 move away from each other, and the rubber shoe can be discharged through the discharge port 22, completing the automatic discharge of the rubber shoe. After discharge, the rubber shoe falls into the receiving box 17. After the external hot air equipment injects hot air into the diversion chamber 18, the hot air is diverted through multiple exhaust ports 19 and discharged into the receiving box 17. This allows for a secondary vulcanization treatment of the rubber shoe inside the receiving box 17, further crosslinking the rubber molecules and improving the physical properties of the rubber shoe.
