Description

Technical Field

[0001] This utility model relates to the field of vulcanization equipment technology, and more specifically to a vulcanizing machine for rubber tires. Background Technology

[0002] As a key component of modern transportation vehicles, the quality and performance of rubber tires directly affect traffic safety and the overall operating condition of vehicles. The vulcanization process plays a central role in the production of rubber tires. Through specific temperature, pressure, and time conditions, it promotes cross-linking reactions in rubber molecules, thereby significantly improving important performance indicators such as strength, wear resistance, and aging resistance of the rubber.

[0003] Existing vulcanization equipment has defects, such as producing a strong pungent odor after vulcanization, especially for large-volume rubber vulcanization of rubber tires. This affects the working environment and may even harm operators during long-term production operations. In addition, the rubber tires are at a high temperature after vulcanization and require a certain cooling time, which affects work efficiency. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a vulcanizing machine for rubber tires to solve the problem that traditional rubber tire vulcanizing machines in the background art have difficulty in treating the irritating odor of rubber.

[0005] This utility model provides the following technical solution: a vulcanizing machine for rubber tires, including a base, a lower mold installed on the top of the base, a hydraulic lifting mechanism connected to the top of the base via a column, an upper mold installed at the bottom output end of the hydraulic lifting mechanism, a ventilation component provided on the side wall of the upper mold, the ventilation component being sleeved on the side wall of the lower mold, the lower mold being provided with a one-way air inlet and a one-way air outlet, the one-way air outlet of the lower mold being connected to an exhaust system via an exhaust hose, and the one-way air inlet of the ventilation component being connected to an air supply mechanism via an air inlet hose, the air supply mechanism being used for supplying air to the inside of the ventilation component and for airflow cooling.

[0006] Furthermore, a number of sliders are fixedly connected to the top of the inner wall of the ventilation component, and a number of sliding grooves are opened on the side wall of the upper mold, and the sliders slide and fit together in the sliding grooves.

[0007] Furthermore, the ventilation assembly includes an annular cylinder, the inner wall of which is provided with an intake annular chamber and an exhaust annular chamber. The intake annular chamber is connected to an intake hose through a one-way valve, and the exhaust annular chamber is connected to an exhaust hose through a one-way valve.

[0008] Furthermore, the air intake annular chamber includes an annular chamber main component, an annular wall is fixedly connected to the inner wall of the annular chamber main component, and a plurality of airflow holes communicating with the inner cavity of the annular wall are opened on one side wall of the annular wall, and the plurality of airflow holes are distributed in a ring shape along one side wall of the annular wall.

[0009] Furthermore, all of the aforementioned airflow holes are inclined in a clockwise direction, and the diameter of the airflow holes facing one side wall of the annular wall is larger than the diameter in the inward direction.

[0010] Furthermore, the exhaust ring chamber includes a bottom ring and a top ring. The inner walls of the bottom ring and the top ring are fixedly connected by a second ring wall. The inner wall of the second ring wall has several through holes. A ring cover is fitted onto the side wall of the top ring. The top of the ring cover is fixed to the top of the top ring by several screws. A sealing ring one and a sealing ring two are respectively provided on the side wall of the top ring and the top of the bottom ring. The sealing ring one fits into the inner wall of the ring cover, and the sealing ring two fits into the bottom end of the ring cover. An interface for connecting to a one-way valve is provided on the side wall of the ring cover.

[0011] Furthermore, the air supply mechanism includes a liquid tank, an air inlet connected to the outside of the liquid tank and connected to a high-pressure air pump, a heat exchanger inside the liquid tank, an air inlet end of the heat exchanger connected to the air inlet, an exhaust end of the heat exchanger passing through the outside of the liquid tank and connected to an air inlet hose, and several semiconductor cooling chips connected to the inside of the liquid tank at the bottom of the liquid tank, the inside of the liquid tank being used to store coolant.

[0012] Furthermore, a heat dissipation mechanism is provided at the bottom of the liquid tank, which is used to dissipate heat from the heating surfaces of several semiconductor cooling chips. The heat dissipation mechanism consists of several cooling fans.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] This utility model achieves a closed-loop ventilation effect by combining a ventilation component and an air supply mechanism. After the rubber tire is vulcanized, it is isolated in the inner cavity of the ventilation component. Through closed-loop ventilation, the pungent odor can be directly introduced into the exhaust system, avoiding the impact on the working environment and operators.

[0015] Based on the above, the air supply mechanism is further improved so that cold air is introduced when the air supply mechanism exchanges air inside the air exchange component. Under the action of cold air, the cooling speed of the vulcanized rubber can be accelerated, so that it can be quickly shaped, which helps to stabilize the structure of the vulcanized rubber and can improve production efficiency to a certain extent.

[0023] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] Reference Figures 1-2 This utility model provides a vulcanizing machine for rubber tires, including a base 1, a lower mold 2 installed on the top of the base 1, a hydraulic lifting mechanism 4 connected to the top of the base 1 via a column 3, an upper mold 5 installed at the bottom output end of the hydraulic lifting mechanism 4, a ventilation component 6 provided on the side wall of the upper mold 5, the ventilation component 6 being sleeved on the side wall of the lower mold 2, the lower mold 2 being provided with a one-way air inlet and a one-way air outlet, the one-way air outlet of the lower mold 2 being connected to an exhaust system via an exhaust hose 8, and the one-way air inlet of the ventilation component 6 being connected to an air supply mechanism 9 via an air inlet hose 7, the air supply mechanism 9 being used for supplying air to the inside of the ventilation component 6 and for airflow cooling.

[0025] During vulcanization, raw rubber tires are added to the lower mold 2. The hydraulic lifting mechanism 4 drives the upper mold 5 to connect with the lower mold 2 for sealed vulcanization. During this process, the ventilation component 6 is fitted into the side wall of the lower mold 2. After vulcanization, the hydraulic lifting mechanism 4 moves the upper mold 5 upward, opening a gap between the lower mold 2 and the upper mold 5. The ventilation component 6 remains fitted into the side wall of the lower mold 2, sealing the gap between the lower mold 2 and the upper mold 5. During this process, the pungent odor after vulcanization remains in the sealed space and does not mix with the outside. The air supply mechanism 9 outputs cold air, which enters the ventilation component 6 through the air inlet hose 7 and is discharged into the exhaust system through the exhaust hose 8. Under the action of the cold air flow, the pungent odor is directly carried out to the exhaust system to avoid mixing with the working ring. On the other hand, the cold air enters the ventilation component 6 and comes into contact with the vulcanized rubber tire, increasing the cooling speed of the vulcanized rubber and accelerating the setting.

[0026] Reference Figure 2 The top of the inner wall of the ventilation component 6 is fixedly connected to several sliders 10, and the side wall of the upper mold 5 is provided with several sliding grooves, in which the sliders 10 slide and are connected.

[0027] When in use, when the upper mold 5 moves down and closes with the lower mold 2, the ventilation component 6 first fits into the side wall of the lower mold 2. After touching the bottom, the upper mold 5 continues to move down, and the slider 10 slides upward behind the groove on the side wall of the upper mold 5 until the lower mold 2 and the upper mold 5 are closed. The ventilation component 6 completely wraps the side wall of the lower mold 2 and the upper mold 5. When the upper mold 5 moves up, the ventilation component 6 does not move under the influence of gravity until the slider 10 reaches the bottom of the groove. Then, the upper mold 5 can drive the ventilation component 6 to move up. When the ventilation component 6 reaches the edge of the side wall of the lower mold 2, it stops. At this time, the ventilation component 6 can achieve the sealing effect at the gap between the lower mold 2 and the upper mold 5.

[0028] Reference Figure 3 The ventilation assembly 6 includes an annular cylinder 61. The inner wall of the annular cylinder 61 is provided with an intake annular chamber 62 and an exhaust annular chamber 63. The intake annular chamber 62 is connected to the intake hose 7 through a one-way valve 65, and the exhaust annular chamber 63 is connected to the exhaust hose 8 through a one-way valve 64.

[0029] By setting one-way air valve 64 and one-way air valve 65, the overflow of gas after sulfidation into the gas supply mechanism 9 can be prevented, and the gas in the exhaust system can be prevented from flowing back into the ventilation assembly 6.

[0030] Reference Figure 4The air intake annular compartment 62 includes an annular compartment main component 621. An annular wall 622 is fixedly connected to the inner wall of the annular compartment main component 621. A plurality of airflow holes 623 communicating with the inner cavity of the annular wall 622 are opened on the side wall of the annular wall 622. The plurality of airflow holes 623 are distributed in a ring shape along the side wall of the annular wall 622.

[0031] With this setup, the gas entering the intake annular chamber 62 through the one-way air valve 65 first enters the main annular chamber 621 and is intercepted by the annular wall 622. Under the action of air pressure, the airflow flows through several annular walls 622. When the airflow cools the vulcanized rubber in multiple directions, the cooling uniformity is improved.

[0032] Reference Figure 4 Several airflow holes 623 are inclined in a clockwise direction, and the diameter of the airflow holes 623 facing the side wall of the annular wall 622 is larger than the diameter facing the inner wall.

[0033] This design allows the airflow from several airflow holes 623 to form a vortex, which facilitates the removal of the pungent odor after rubber vulcanization. The difference in the diameter of the airflow holes 623 increases the flow rate when the airflow passes through.

[0034] Reference Figure 5 The exhaust ring chamber 63 includes a bottom ring 631 and a top ring 632. The inner walls of the bottom ring 631 and the top ring 632 are fixedly connected by a second ring wall 633. The inner wall of the second ring wall 633 has several through holes. A ring cover 634 is fitted onto the side wall of the top ring 632. The top of the ring cover 634 is fixed to the top of the top ring 632 by several screws 635. A sealing ring 636 and a sealing ring 637 are respectively provided on the side wall of the top ring 632 and the top of the bottom ring 631. The sealing ring 636 fits into the inner wall of the ring cover 634, and the sealing ring 637 fits into the bottom end of the ring cover 634. The side wall of the ring cover 634 is provided with an interface for connecting to a one-way valve 64.

[0035] The sulfurized gas inside the ventilation assembly 6 is driven by the airflow to pass through the through hole of the second ring wall 633 and enter between the top ring 632 and the bottom ring 631. Then it flows out through the interface of the ring cover 634 and the one-way valve 64. During this process, impurities or oil stains in the sulfurized gas are easy to adhere to the bottom ring 631, the top ring 632, and the ring cover 634. Due to the structural design of the exhaust ring chamber 63, it can be cleaned by removing the screws 635 and then removing the ring cover 634.

[0036] Reference Figure 6The air supply mechanism 9 includes a liquid tank 91, an air inlet 92 connected to the outside of the liquid tank 91, the air inlet 92 is connected to a high-pressure air pump, a heat exchanger 93 is installed inside the liquid tank 91, the air inlet end of the heat exchanger 93 is connected to the air inlet 92, the exhaust end of the heat exchanger 93 passes through the outside of the liquid tank 91 and is connected to the air inlet hose 7, and a number of semiconductor cooling chips 94 connected to the inside of the liquid tank 91 are installed at the bottom of the liquid tank 91. The inside of the liquid tank 91 is used to store coolant.

[0037] During use, a high-pressure airflow is input into the air inlet 92 via a high-pressure air pump. The airflow exchanges heat with the coolant inside the heat exchanger 93 and then is output to the air exchange assembly 6. The coolant is cooled by several semiconductor cooling chips 94.

[0038] Reference Figure 6 The liquid tank 91 is equipped with a heat dissipation mechanism at the bottom, which is used to dissipate heat from the heating surfaces of several semiconductor cooling chips 94. The heat dissipation mechanism consists of several cooling fans.
