Description

Technical Field

[0001] This utility model relates to the field of shoe sole production technology, specifically to a vulcanizing machine for shoe sole curing. Background Technology

[0002] Currently, shoe sole production involves selecting appropriate main materials such as rubber or thermoplastic elastomers, along with various compounding agents such as vulcanizing agents, accelerators, activators, fillers, and antioxidants, based on the shoe's performance requirements. For example, commonly used natural rubber has good elasticity and abrasion resistance, while styrene-butadiene rubber (SBR) has better aging resistance. These materials can be used to create sole blanks according to actual needs. The sole blanks are then placed in a vulcanizing mold, where they undergo a vulcanization reaction under specific temperature, pressure, and time conditions. During vulcanization, the rubber molecular chains form a three-dimensional network structure through cross-linking reactions, thereby giving the sole good strength, elasticity, and abrasion resistance.

[0003] However, when using existing vulcanizing machines, in order to prevent the soles from sticking to the mold surface during the vulcanization process, workers usually need to manually apply a layer of release agent to the mold on the upper and lower heating plates, which increases the workload of workers. Moreover, existing vulcanizing machines produce harmful gases such as sulfur dioxide and hydrogen sulfide when vulcanizing soles, which are easily inhaled by workers and affect their health.

[0032] like Figures 1 to 5 As shown, this utility model provides a vulcanizing machine for shoe sole curing, including a base 1. A support frame 2 is mounted on the top of the base 1. An electric slide rail 3 is mounted at the rear position between the left and right inner side walls of the support frame 2. A mounting frame 4 is mounted in front of the slide table of the electric slide rail 3. Spray pipes 5 are laid on the top and bottom of the mounting frame 4. Multiple evenly distributed nozzles 6 are mounted on the spray pipes 5. The nozzles of the upper nozzles 6 are set upwards, and the nozzles of the lower nozzles 6 are set downwards. A placement groove is provided on the back of the base 1. A release agent storage tank 7 and a water pump 8 are placed in the placement groove. A water outlet is provided on the bottom side of the release agent storage tank 7, and the water outlet is connected to the water inlet of the water pump 8. The water outlet is connected to the water inlet of the spray pipe 5 via the first connecting pipe 9. The electric slide rail 3 can control the left and right displacement of the spray pipe 5. The water pump 8 can pump the release agent stored in the release agent storage tank 7 into the spray pipe 5, and then spray the release agent upward and downward through the nozzle 6. The release agent storage tank 7 is made of polyethylene plastic. Polyethylene plastic tanks are acid and alkali resistant and tough, and can effectively store release agent. The top of the release agent storage tank 7 is provided with a liquid filling port, and a sealing cap is provided on the liquid filling port. The purpose of the sealing cap is to prevent the release agent stored in the tank from evaporating and deteriorating. The first connecting pipe 9 is made of polyethylene hose, and the hose will not hinder the left and right movement of the spray pipe 5.

[0033] A lower heating plate 10 is mounted on the top of the base 1. A hydraulic rod 11 is mounted on the bottom inner side of the support frame 2. A base plate 12 is mounted on the bottom end of the output rod of the hydraulic rod 11. An upper heating plate 13 is mounted on the bottom surface of the base plate 12, and the upper heating plate 13 is located directly above the lower heating plate 10. A cover 14 is provided above the base plate 12. Four guide rods 15 arranged in a rectangular array are mounted on the top of the base plate 12. The four guide rods 15 and the output rod of the hydraulic rod 11 all pass through the top of the cover 14. A baffle 16 is mounted on the top of each of the four guide rods 15, and a spring is fitted on the outside of each of the four guide rods 15. Spring 17 is located between the top of the cover 14 and the bottom of the baffle 16 and is always in a compressed state. When the hydraulic rod 11 controls the upper heating plate 13 to press down, the cover 14 will first contact the top of the machine base 1, and then the spring 17 will start to deform until the upper heating plate 13 presses on the lower heating plate 10. At this time, the cover 14 completely covers the upper and lower heating plates inside, which can effectively prevent the harmful gases generated during the vulcanization process from drifting away. When the hydraulic rod 11 controls the upper heating plate 13 to reset, the cover 14 will also return to its original position under the elastic force of the spring 17 and its own gravity.

[0034] The cover 14 is provided with an air inlet and an air outlet. A one-way valve 18 is installed on the air inlet. A gas purifier 22 is installed on the top of the support frame 2. The air inlet of the gas purifier 22 is connected to the air outlet of the cover 14 through a second connecting pipe 23. The gas purifier 22 is activated during the vulcanization process of the shoe sole to draw in the harmful gases generated during the vulcanization process for purification, preventing the harmful gases from drifting into the air and affecting the health of the workers. The purpose of setting the air inlet on the cover 14 is to maintain the air pressure inside the cover 14. After the harmful gases inside the cover 14 are drawn away, outside air can enter the cover 14 through the air inlet to maintain its internal air pressure and prevent the cover 14 from being sucked onto the machine base 1 due to internal negative pressure. The second connecting pipe 23 is made of fluoroplastic hose. Fluoroplastic hose is resistant to high temperature and corrosion, and can effectively prevent corrosion from harmful gases such as sulfur dioxide and hydrogen sulfide. Moreover, the hose will not hinder the up and down movement of the cover 14.

[0035] A first sealing ring 19 is installed at the bottom edge of the cover 14. A second sealing ring 20 is installed inside the through hole through which the output rod of the hydraulic rod 11 passes through the cover 14. A third sealing ring 21 is installed inside the through hole through which the four guide rods 15 pass through the cover 14. When the cover 14 contacts the top of the base 1, the cooperation of the three sealing rings can keep the inside of the cover 14 sealed, thereby effectively preventing the leakage of harmful gases during the vulcanization process.

[0036] Working principle and usage process of this utility model:

[0037] Before using the vulcanizing machine for curing shoe soles, first start the electric slide rail 3 and move the spray pipe 5 between the upper heating plate 13 and the lower heating plate 10. Then start the water pump 8 and pump the release agent stored in the release agent storage tank 7 into the spray pipe 5. Then spray it evenly onto the mold of the upper heating plate 13 and the lower heating plate 10 through the nozzle 6 on the spray pipe 5. Then start the electric slide rail 3 again and move the spray pipe 5 to the right side of the cover 14.

[0038] When using the vulcanizing machine, the shoe sole blank is placed into the mold of the lower heating plate 10, and then the machine is started. The hydraulic rod 11 controls the upper heating plate 13 to press down. The cover 14 first contacts the top of the machine base 1, and then the spring 17 begins to deform until the upper heating plate 13 presses on the lower heating plate 10 to start vulcanizing the shoe sole. During the vulcanization process, the gas purifier 22 is activated to absorb and purify the harmful gases generated during the vulcanization process. After the shoe sole vulcanization is completed, the hydraulic rod 11 controls the upper heating plate 13 to return to its original position. Finally, the shoe sole can be removed from the mold of the lower heating plate 10.

[0039] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
