Description

Technical Field

[0001] This utility model relates to the field of vulcanization equipment technology, specifically to an electromagnetic heating tire vulcanization device. Background Technology

[0002] Tire vulcanization is a process in which rubber compounds with certain plasticity and viscosity are transformed into soft, elastic rubber products or hard, tough rubber products under certain external conditions through the action of chemical or physical factors, thereby obtaining the performance characteristics required for use.

[0003] Currently, in vulcanization equipment, a tire is placed inside a molding mold, and an electromagnetic heater is attached to the outside of the mold. The electromagnetic heater heats the tire inside the mold to drive the tire through vulcanization and ensure tire conversion. However, during the vulcanization process using the electromagnetic heater, the electromagnetic heater is attached to the outside of the mold, which means that the electromagnetic heater is not in direct contact with the tire. This results in different distances between the electromagnetic heater and the tire at different positions, leading to uneven heating of the tire during vulcanization and incomplete vulcanization in some areas, which in turn affects the forming quality of the tire. Therefore, we propose an electromagnetic heating type tire vulcanization device. Utility Model Content

[0004] To address the shortcomings of existing electromagnetic heating tire vulcanizing devices, this invention provides an electromagnetic heating tire vulcanizing device. This device features a lower mold fitted inside an electromagnetic heater. When the electromagnetic heater is activated to vulcanize the tire, a gear drives a rotating seat to rotate, maintaining rotation during tire vulcanization. This ensures that the tire and the inner side of the gear remain in a dynamic state, improving the uniformity of heating and thus enhancing tire quality. This invention solves the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: an electromagnetic heating tire vulcanizing device, including a bracket, a rotating seat movably sleeved inside the bracket, a connecting sleeve fixedly connected to the inner side of the rotating seat, a lower mold fixedly connected to the upper part of the connecting sleeve, a lead screw installed inside the connecting sleeve, a tire tread shaping mold threaded onto the outer thread of the lead screw, a first hydraulic rod installed on the inner thread of the lower mold, an inner extrusion sleeve fixedly connected to the outer side of the first hydraulic rod, second hydraulic rods installed inside the two sides of the bracket, an upper cover plate installed at the top of the second hydraulic rod, and an electromagnetic heater fixedly connected to the lower part of the upper cover plate.

[0006] Preferably, a gear is installed on one side of the bracket, and the gear installed at one end of the gear output shaft meshes with an auxiliary gear installed on the outside of the rotating seat.

[0007] Preferably, the tread shaping mold is semi-circular and is fitted onto the upper part of the upper end of the lower mold.

[0008] Preferably, the lower part of the upper cover plate is fixedly connected to an upper mold, and the upper mold is movably sleeved on the upper part of the tread shaping mold.

[0009] Preferably, an electromagnetic induction coil is installed inside the electromagnetic heater, and the electromagnetic heater is sleeved on the outside of the tire tread shaping mold.

[0010] Preferably, a gas transmission pipe is installed inside the lower mold and on one side of the first hydraulic rod, and an air pump is connected to the outside of the gas transmission pipe. The gas transmission pipe is connected to the inside of the inner extrusion sleeve.

[0011] Preferably, the two ends of the inner extrusion sleeve are respectively installed between the lower mold and the top of the first hydraulic rod, and the wheel to be vulcanized is clamped between the lower mold, the tread shaping mold, the upper mold and the inner extrusion sleeve.

[0012] Compared with existing electromagnetic heating tire vulcanizing devices, this invention has the following advantages:

[0013] 1. In this electromagnetic heating tire vulcanizing device, a tire is placed on the upper part of the lower mold. At the same time, the electromagnetic heater moves to the outside of the upper end of the lower mold and can be sleeved on the outside of the tire tread shaping mold. The electromagnetic heater can vulcanize the tire, and the gear drives the rotating seat to rotate. That is, when the tire is vulcanized, it drives the tire to rotate, ensuring that the tire vulcanization heating is uniform and avoiding uneven heating, which would affect the vulcanization effect.

[0014] 2. The electromagnetic heating tire vulcanizing device uses a tread shaping mold fitted onto the upper part of the lower mold. After the tire is fitted onto the outside of the inner extrusion sleeve, the tread shaping mold is moved inward. The lower mold, tread shaping mold, upper mold, and inner extrusion sleeve provide vulcanizing and molding space for the tire. Furthermore, the electromagnetic heater and the molding device are not integrated into a single design, meaning the electromagnetic heater can heat vulcanizing equipment of different shapes and sizes.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An electromagnetic heating tire vulcanizing device includes a bracket 1, a rotating seat 2 movably sleeved inside the bracket 1, a connecting sleeve 4 fixedly connected to the inner side of the rotating seat 2, the connecting sleeve 4 adjusting the position of a lower mold 5, the upper part of the connecting sleeve 4 fixedly connected to the lower mold 5, a lead screw 6 installed inside the connecting sleeve 4, the lead screw 6 driving the position of a tread shaping mold 7 for adjustment, the external thread of the lead screw 6 sleeved to the tread shaping mold 7, the tread shaping mold 7 providing the forming shape for the tire, a first hydraulic rod 9 installed internally in the lower mold 5, an inner extrusion sleeve 10 fixedly connected to the outside of the first hydraulic rod 9, after the inner extrusion sleeve 10 is inflated, it can extrude from the inside of the tire to ensure that the tire fits against the inside of the tread shaping mold 7, a second hydraulic rod 11 installed inside both sides of the bracket 1, an upper cover plate 12 installed at the top of the second hydraulic rod 11, an electromagnetic heater 13 fixedly connected to the lower part of the upper cover plate 12, the electromagnetic heater 13 is started to perform electromagnetic heating, thus vulcanizing the tire.

[0023] Please see Figure 2A gear 3 is installed on one side of the bracket 1. The gear installed at one end of the output shaft of the gear 3 meshes with the auxiliary gear installed on the outside of the rotating seat 2. The rotating seat 2 is sleeved on the upper part of the bracket 1. At the same time, a tire limiting forming mold is installed on the upper part of the rotating seat 2. When the upper cover plate 12 heats and vulcanizes the tire, the gear 3 drives the rotating seat 2 to rotate. That is, the tire is heated in a rotating state inside the mold, which ensures that the external heating of the tire is sufficient and effectively avoids uneven tire heating due to different distances and obstacles between the tire and the upper cover plate 12, which would affect the vulcanization quality of the tire.

[0024] Please see Figure 3 The tread shaping mold 7 is semi-circular and is fitted onto the upper part of the lower mold 5. The tread shaping mold 7 is positioned on the upper part of the tread shaping mold 7. When the tire material is placed, the screw 6 is activated, which drives the tread shaping mold 7 to move outward. At the same time, after the tire material is placed outside the inner extrusion sleeve 10, the tread shaping mold 7 is controlled to move inward. That is, the tread shaping mold 7 defines the tread pattern and shape of the tire. Meanwhile, the tire is heated and squeezed inside the inner extrusion sleeve 10, which allows the tire to undergo vulcanization and shaping treatment.

[0025] Please see Figure 2 The upper cover plate 12 is fixedly connected to the lower part of the upper mold 8. The upper mold 8 is movably sleeved on the upper part of the tread shaping mold 7. The upper mold 8 is fixedly connected to the lower end of the upper cover plate 12. When the upper cover plate 12 moves up and down, the upper cover plate 12 drives the upper mold 8 to adjust its position. At the same time, the upper mold 8 can be sleeved on the upper end of the tread shaping mold 7 to ensure that the upper mold 8 seals the upper end of the tread shaping mold 7 and ensures that the equipment forms a forming space.

[0026] Please see Figure 3 An electromagnetic induction coil is installed inside the electromagnetic heater 13. The electromagnetic heater 13 is sleeved on the outside of the tread shaping mold 7. Since the electromagnetic induction coil is installed on the outside of the electromagnetic heater 13, when the tire needs to be vulcanized, the electromagnetic induction device is activated by controlling the electromagnetic heater 13 to be sleeved on the outside of the tread shaping mold 7. The electromagnetic induction device can heat the tire placed inside the tread shaping mold 7 to ensure that heat energy is provided during the tire vulcanization process.

[0027] Please see Figure 5A gas transmission pipe 14 is installed inside the lower mold 5 and on one side of the first hydraulic rod 9. An air pump is connected to the outside of the gas transmission pipe 14. The gas transmission pipe 14 is connected to the inside of the inner extrusion sleeve 10. After the first hydraulic rod 9 is extended or retracted, the thickness of the inner extrusion sleeve 10 can be adjusted. At the same time, gas is injected into the inside of the inner extrusion sleeve 10 through the gas transmission pipe 14. The gas can drive the inner extrusion sleeve 10 to be extruded to the outside, ensuring the tire extrusion forming process.

[0028] Please see Figure 2 The two ends of the inner extrusion sleeve 10 are respectively installed between the lower mold 5 and the top of the first hydraulic rod 9. The wheel to be vulcanized is clamped between the lower mold 5, the tread shaping mold 7, the upper mold 8 and the inner extrusion sleeve 10. The tire is clamped by the lower mold 5, the tread shaping mold 7, the upper mold 8 and the inner extrusion sleeve 10. At the same time, during the heating of the equipment and the extrusion of the inner extrusion sleeve 10 to the outside, the tire is ensured to adhere to the inner side of the tread shaping mold 7 to ensure its forming process.

[0029] Working principle: In use, the second hydraulic rod 11 is activated to control the upper cover plate 12 to move upward. At the same time, the lead screw 6 is activated, which drives the tread shaping mold 7 to move to both sides. Simultaneously, the tire is placed outside the inner extrusion sleeve 10. The tread shaping mold 7 is controlled to move inward. At the same time, the second hydraulic rod 11 is activated to control the upper cover plate 12 to move downward. The electromagnetic heater 13 is sleeved on the side of the tread shaping mold 7, and the upper mold 8 is sleeved on the upper part of the tread shaping mold 7. Simultaneously, the first hydraulic rod 9 and the gas transmission pipe 14 are activated, which can drive the inner extrusion sleeve 10 to extrude from the inside. The electromagnetic heater 13 is activated to perform electromagnetic heating treatment, and the heat generated is used to heat and vulcanize the tire.
