Description

Technical Field

[0001] The invention relates to the technical field of tire molds, and in particular to a tire mold structure with a novel heating method. Background Art

[0002] The tire mold is a very important carrier in the tire manufacturing process. During the vulcanization process of the tire, the tire mold needs to be placed between the upper hot plate and the lower hot plate of the vulcanizer and heated to a temperature of about 175°C to maintain vulcanization.

[0003] At present, tire heating molds are divided into steam type and hot plate type according to different heating methods. Steam type tire heating molds cause a lot of energy loss and environmental pollution during production, and require a lot of space; hot plate type tire heating molds occupy a small area and have high heat transfer efficiency.

[0004] However, the heat plate in the existing hot plate type tire heating mold radiates heat in all directions, and the heat radiated from the side of the hot plate away from the tread block cannot be reasonably utilized, resulting in a waste of resources. In addition, in order to improve the heat transfer efficiency during the production of the tire heating mold, the tread blocks therein are mostly made of materials with high thermal conductivity. This results in the heat of the tread blocks being quickly dissipated in the gap between two vulcanization operations, which not only wastes resources but also reduces production efficiency.

[0005] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention

[0006] In view of the above-mentioned defects, the purpose of the present invention is to provide a tire mold structure with a new heating method, which has a simple structure and is easy to use. It can not only quickly heat up the upper side plate, the lower side plate and the pattern block, but also keep the pattern block warm in the gap between two vulcanization operations, which can not only improve work efficiency but also save resources.

[0007] In order to achieve the above-mentioned purpose, the present invention provides a tire mold structure with a new heating method, including: an upper cover, whose bottom surface is provided with an upper side plate, the bottom surface of the upper cover is provided with a middle sleeve, and the middle sleeve is arranged outside the upper side plate; a lower cover, whose top surface is provided with a lower side plate, the top surface of the lower cover is slidably provided with a plurality of bow-shaped seats, the plurality of bow-shaped seats are evenly arranged outside the lower side plate, and the inner ring side walls of the bow-shaped seats are provided with pattern blocks; the upper cover, the lower cover and the bow-shaped seats are all provided with oil radiators.

[0008] According to the tire mold structure with a novel heating method of the present invention, a heat-insulating plate is provided on the outer side wall of the upper cover, the lower cover and the middle sleeve.

[0009] According to the tire mold structure with a new heating method of the present invention, an insulation component is provided in the bow-shaped seat, and the insulation component includes a U-shaped tube, a piston and a connecting rod. A heat storage liquid is provided in the U-shaped tube. The U-shaped tube includes two vertical pipes and a connecting pipe connected to the bottom of the vertical pipes. The two vertical pipes are respectively located on both sides of the oil radiator device. The top of the vertical pipe close to the pattern block is connected to the receiving groove. A piston is slidably provided in the receiving groove, and the top surface of the piston is connected to the connecting rod passing through the receiving groove.

[0010] According to the tire mold structure with a novel heating method of the present invention, a limiting plate is provided at the top end of the connecting rod.

[0011] According to the tire mold structure with a novel heating method of the present invention, a spring is sleeved outside the connecting rod, and two ends of the spring respectively abut against the bottom surface of the limiting plate and the top surface of the bow-shaped seat.

[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0018] See also Figure 1 and Figure 2 The present invention provides a tire mold structure with a novel heating method, including an upper cover 1, a lower cover 2 and a middle cover 3. The present invention is installed on a common vulcanizer (not shown in the figure), wherein the upper cover 1 is connected to the top seat of the vulcanizer, and the lower cover 2 is connected to the base of the vulcanizer. The upper cover 1 can be raised and lowered synchronously with the top seat of the vulcanizer. The upper cover 1 is provided with an upper side plate 11 on the bottom surface, and the lower cover 2 is provided with a lower side plate 21 on the top surface. The upper side plate 11 and the lower side plate 21 can cooperate with the tire blank. The upper cover 1 is provided with a middle cover 3 on the bottom surface, and the middle cover 3 is arranged outside the upper side plate 11. The top surface of the lower cover 2 is provided with a plurality of arch seats 4 for sliding. The inner ring side wall of the middle cover 3 is provided with an inclined surface that cooperates with the arch seat 4. The inner ring side wall of the arch seat 4 is provided with a pattern block 41. When the top seat and the base of the vulcanizer are matched, the upper inclined surface of the middle cover 3 cooperates with the arch seat 4, so that the pattern block 41 abuts and squeezes the side of the tire blank. The upper side plate 11, the lower side plate 21 and the arched seat 4 are all provided with an oil radiator device 5, which can provide heat for tire vulcanization.

[0019] See also Figure 1 and Figure 2 A heat preservation component 7 is provided in the bow-shaped seat 4, and the heat preservation component 7 includes a U-shaped tube 71, a piston 72 and a connecting rod 73. A plurality of U-shaped tubes 71 are provided in the bow-shaped seat 4. The U-shaped tube 71 includes two vertical pipes and a connecting pipe connecting the bottoms of the two vertical pipes. The two vertical pipes are respectively located on both sides of the oil heater device 5. The connecting pipe is arranged below the oil heater device 5. The U-shaped tube 71 is provided with heat storage liquid. The top of the vertical pipe of the U-shaped tube 71 located between the oil heater device 5 and the pattern block 41 is connected to the accommodating chamber. The accommodating chamber is arranged at the top of the bow-shaped seat 4. A piston 72 is slidably provided in the accommodating chamber. The top of the piston 72 is connected to a plurality of connecting rods 73 passing through the accommodating chamber. When the vulcanizer is vulcanizing the tire blank, the connecting rod 73 is squeezed by the upper cover 1, and the connecting rod 73 drives the piston 72 to move downward, so that the heat storage liquid in the U-shaped tube 71 enters the vertical pipe away from the pattern block 41. At this time, the oil heater device 5 starts and dissipates heat to the surroundings. The heat storage liquid can collect the heat dissipated by the oil heater device 5 in the direction away from the pattern block 41, and the heat storage liquid is located in the vertical pipe away from the pattern block 41 during vulcanization, which can avoid the heat storage liquid affecting the oil heater device 5 to transfer heat to the pattern block 41; when the vulcanization is completed, the upper cover 1 moves upward under the action of the top seat of the vulcanizer, and under the action of the force of the flow of the heat storage liquid, the connecting rod 73 can drive the piston 72 to rise slowly, and part of the heat storage liquid enters the vertical pipe close to the pattern block 41. The heat stored in the heat storage liquid is used to keep the pattern block 41 warm, which can save resources.

[0020] See also Figure 2 Preferably, a limit plate 74 is provided at the top of the connecting rod 73, and a spring is provided on the outer sleeve of the connecting rod 73, and the two ends of the spring respectively abut against the bottom surface of the limit plate 74 and the top surface of the bow seat 4. When the spring is in a natural state, the piston 72 is located at the top of the accommodating groove, and the heat storage liquid is all located in the vertical pipe close to the pattern block 41, which can maximize the utilization of the heat stored in the heat storage liquid.

[0021] See also Figure 2 Preferably, the top surface of the bow seat 4 is provided with a groove that cooperates with the limit plate 74. When the top seat of the vulcanizer cooperates with the base, the limit plate 74 enters the groove, which can prevent the limit plate 74 from affecting the cooperation between the upper side plate 11, the lower side plate 21 and the pattern block 41, thereby ensuring product quality.

[0022] See also Figure 1 Preferably, the outer surfaces of the upper cover 1, the lower cover 2 and the middle sleeve 3 are all paved with insulation boards 6, which can not only play a heat insulation role to prevent people from being scalded, but also reduce heat loss and energy waste.

[0023] During the implementation of the present invention: the vulcanizer is located at the initial position, the top seat does not cooperate with the base, the user places the tire blank on the lower side plate 21, starts the vulcanizer, and the top seat drives the upper cover 1 to descend. During the descent of the upper cover 1, the middle sleeve 3 cooperates with the bow seat 4 to make the pattern block 41 abut against and squeeze the side of the tire blank, the upper cover 1 presses down the limit plate 74, so that the piston 72 moves downward, and the heat storage liquid enters the vertical pipe away from the pattern block 41 under the action of air pressure, and the oil heater device 5 starts to transfer heat to the pattern block 41, and the heat storage liquid absorbs excess heat. After the vulcanization is completed, the upper cover 1 rises, and under the action of the spring, the piston 72 is reset, and the heat storage liquid enters the vertical pipe close to the pattern block 41, and the heat storage liquid keeps the pattern block 41 warm.

[0024] The present invention provides a tire mold structure with a novel heating method. By arranging an oil heater device disposed in an upper cover, a lower cover and a bow-shaped seat, heat can be quickly transferred to the upper side plate, the lower side plate and the pattern block, thereby accelerating the vulcanization process of the tire blank and improving work efficiency. By arranging a heat preservation component, the excess heat emitted by the oil heater device in the bow-shaped seat can be stored, and the pattern block can be insulated in the gap between two vulcanization operations, which can effectively utilize energy, avoid energy waste, and improve work efficiency. In summary, the beneficial effects of the present invention are: the upper side plate, the lower side plate and the pattern block can be quickly heated, and the pattern block can be insulated in the gap between two vulcanization operations, which can not only improve work efficiency but also save resources.

[0025] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
