Description

Technical Field

[0001] The invention relates to the field of tire moulds, in particular to a tire mould capable of saving energy and reducing consumption. Background Art

[0002] Tires are circular elastic rubber products that roll on the ground and are installed on various vehicles or machinery. They are usually installed on metal rims and can support the vehicle body, cushion external impacts, achieve contact with the road surface and ensure the vehicle's driving performance. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects when driving. Therefore, they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, they are also required to have high wear resistance and flexibility resistance, as well as low rolling resistance and heat generation.

[0003] Tire molds are molds used for vulcanization molding of various tires. They are key equipment for tire production. Their technical level and manufacturing quality are crucial to the performance and safety of tires. With the advancement of science and technology and changes in market demand, the tire mold industry is developing in the direction of high precision, high efficiency, environmental protection and energy saving, and will pay more attention to technological innovation and product upgrades in the future.

[0004] In the process of vulcanizing the tire, the existing tire mold needs to heat the entire mold to vulcanize and shape the tire. When the mold is heated, the temperature of each part is the same. However, the thickness of the tread and the sidewall of the tire is different, and the heat required for the sidewall is less than the tread. When heating the tire for vulcanization, in order to meet the vulcanization conditions of the tread, the mold needs to supply enough heat, which will cause excess heat in the sidewall and cause energy waste. Moreover, after the tire is vulcanized, a large amount of heat will be directly dissipated into the air during the mold opening process, causing a large amount of energy waste.

[0005] For example, the utility model with application number CN212472104U discloses a tire mold, whose structure includes a mold shell and a cavity, wherein the mold shell is arranged outside the cavity, the mold shell includes a base, an upper cover, and a guide ring, a heating chamber is arranged inside the guide ring, and the heating chamber includes a first heating chamber and a second heating chamber that are interconnected, a through hole is arranged between the first heating chamber and the second heating chamber, an insulation layer is arranged on the outside of the guide ring, and the insulation layer covers the heating chamber; the thickness of the insulation layer away from the mold opening end is greater than the thickness of the portion close to the mold opening end; the outer portion of the guide ring is stepped The inner side of the thermal insulation layer is arranged to be stepped to match the outer side of the guide ring. When the utility model supports the mold for mold closing, in order to ensure that the difference in the force applied on the upper and lower sides of the mold is reduced, only the step design on the outer side of the guide ring is adopted. On the one hand, when the mold is misplaced, the step is easily notched due to extrusion, which makes the uniformity of the force on the upper and lower sides of the mold worse. On the other hand, during the mold closing process, the middle position of the mold is not evenly applied with force, resulting in greater stress on the middle position of the guide ring. Over time, the guide ring will be deformed, resulting in poor force uniformity of the mold.

[0006] Therefore, based on the above problems, we invented a tire mold that saves energy and reduces consumption. Summary of the invention

[0020] Compared with the prior art, the present invention provides a tire mold that saves energy and reduces consumption, and has the following beneficial effects:

[0021] 1. The energy-saving and consumption-reducing tire mold is provided with a non-step mechanism. The first motor drives two rotating shafts to rotate, the two rotating shafts drive two driving gears to rotate, the two driving gears drive the ring to rotate, the ring drives the half mold to move through a plurality of rotating keys, and at the same time, the second motor drives two moving screws to rotate, the two moving screws drive the disc to move, and the disc drives the oil bag to move until it reaches a suitable position, and then the mold can be opened, and the tire with internal vulcanization completed can be taken out, which is convenient for opening and closing the tire mold. In addition, in the process of mold closing, the ring rotates and the plurality of rotating keys are simultaneously applied with force, and the plurality of rotating keys can simultaneously apply pressure to the half mold, so that each part of the half mold is subjected to the same force, and the force application is more uniform. At the same time, because the ring directly resists the hot oil tank, the stress of each part of the ring is the same, and there will be no deformation caused by uneven stress of the components, that is, a non-step structure is adopted to achieve the effect of uniform force application.

[0022] 2. The energy-saving and consumption-reducing tire mold is provided with an energy-saving mechanism. When the tire is vulcanized, high-temperature oil is provided to the high-temperature tank through the hot oil tank, so that the high-temperature tank is filled with the high-temperature oil. The high-temperature oil conducts heat to the tire tread through the half mold for high-temperature vulcanization. At the same time, the high-temperature oil flows into the annular cavity through the first connecting hole. At the same time, the cold oil tank provides cold oil to the annular cavity through the third supporting pipe to neutralize the heat of the high-temperature oil, thereby providing appropriate heat according to various parts of the tire, avoiding excess energy when vulcanizing the tire, and saving energy. Moreover, when the vulcanization is finished, the cold oil tank is discharged through the third supporting pipe. A support pipe supplies oil to the low-temperature tank to accelerate the cooling of the mold and the tire. When the mold is opened, the tire and the mold have been cooled to a certain extent, so a large amount of heat dissipation is avoided when the mold is opened. At the same time, the heat of the mold and the tire is recovered and then refluxed to the cold oil tank through the third support pipe to preserve the heat. When the hot oil tank needs to be heated later, the low-temperature oil in the cold oil tank is introduced into the hot oil tank through the reflux pipe. Since the oil in the cold oil tank absorbs heat and its temperature is higher than normal temperature, it is not necessary to start heating from normal temperature when heating the oil, which reduces the heat required for heating and saves energy when vulcanizing the tire.

[0023] When the present invention vulcanizes the tire, less energy is required, and there will be no excess energy. Vulcanization is more energy-saving, and the force applied to the tire mold is more uniform, and the opening and closing is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] As introduced in the background technology, the deficiencies in the prior art exist. In order to solve the above technical problems, the present application proposes a tire mold that saves energy and reduces consumption.

[0035] like Figure 1-8 , energy-saving and consumption-reducing tire molds, including,

[0036] A hot oil tank 10 and a cold oil tank 11, two half molds 2 are arranged between the hot oil tank 10 and the cold oil tank 11, the hot oil tank 10 and the cold oil tank 11 are fixedly connected by two transverse plates 12, the two half molds 2 on the left side are slidably connected to the transverse plate 12 by two connecting plates 39, and the two half molds 2 on the right side are fixedly connected to the cold oil tank 11 by two fixing plates 40;

[0037] In order to make each part of the mold evenly stressed when the wheel mold is opened and closed, a non-step mechanism 21 is provided for evenly applying force to the left half mold 2. The non-step mechanism 21 includes a ring 23 rotatably connected to the hot oil tank 10, and the right end of the ring 23 is rotatably connected to multiple rotating keys 22, and the right ends of the multiple rotating keys are rotatably connected to the half mold 2 on the left. The hot oil tank 10 is rotatably penetrated by two rotating shafts 24, and the right ends of the two rotating shafts 24 are coaxially fixedly connected to driving gears 26. The outer wall of the ring 23 is provided with an annular tooth groove meshing with the two driving gears 26. The two rotating shafts 24 are connected by a transmission mechanism 25. It should be noted that the transmission mechanism 25 includes two pulleys 37, and the two pulleys 37 are coaxially fixedly connected to the two rotating shafts 24 respectively, and the two pulleys 37 are connected by synchronous belt transmission. A first motor 27 is installed on the left side of the hot oil tank 10, and the drive shaft of the first motor 27 is coaxially fixedly connected to one of the rotating shafts 24.

[0038] Through the above technical features, the two rotating shafts 24 are driven to rotate by the first motor 27, the two rotating shafts 24 drive the two driving gears 26 to rotate, the two driving gears 26 drive the ring 23 to rotate, and the ring 23 drives the half mold 2 to move through the multiple rotating keys 22. In the process of mold closing, the multiple rotating keys 22 are applied with force at the same time through the rotation of the ring 23, and the multiple rotating keys 22 can apply pressure to the half mold 2 at the same time. When the mold is closed, the various parts of the half mold 2 are subjected to the same force, and the force is more uniform. At the same time, since the upper side of the ring 23 directly resists the hot oil tank 10, the stress of various parts of the ring 23 is the same, and there will be no deformation caused by uneven stress of the components.

[0039] In order to save energy during tire vulcanization, an energy-saving mechanism 1 is provided for vulcanization molding of tire embryos. The energy-saving mechanism 1 includes a mold groove 3, a high-temperature groove 4, and a low-temperature groove 5 arranged on a half mold 2. The low-temperature groove 5 is located between the high-temperature groove 4 and the mold groove 3. An annular cavity 6 is provided in the half mold 2. The two annular cavities 6 are connected through an associated pipe 8. The annular cavity 6 and the high-temperature groove 4 are connected through a first connecting hole 7. The annular cavity 6 and the low-temperature groove 5 are connected through a second connecting hole 9. The hot oil tank 10 is connected to the high-temperature groove 4 through a connecting pipe 13. The cold oil tank 11 is connected to the low-temperature groove 5 through a first supporting pipe 14. A second supporting pipe 15 is connected between the high-temperature groove 4 and the cold oil tank 11. A third supporting pipe 16 is connected between the annular cavity 6 and the cold oil tank 11. It needs to be explained It is worth mentioning that the first support tube 14, the second support tube 15 and the third support tube 16 are all made of stainless steel metal. It is worth mentioning that the first connecting hole 7, the second connecting hole 9, the first support tube 14, the second support tube 15 and the third support tube 16 are all provided with solenoid valves, and the middle part of the two half molds 2 is provided with a through hole 17, and the same oil bag 18 is sealed and inserted in the two through holes 17; both ends of the oil bag 18 are respectively connected to the hot oil tank 10 and the cold oil tank 11 through a connecting pipe 19. Furthermore, the associated pipe 8 and the connecting pipe 13 are both corrugated pipes, and the connecting pipe 19 is detachable. It should be noted that the cold oil tank 11 is connected to the hot oil tank 10 through the reflux pipe 38. It should be noted that the connecting pipe 19 and the oil bag 18 are inserted in an inserted manner.

[0040] Through the above technical features, when the tire is vulcanized, the hot oil tank 10 provides high-temperature oil to the high-temperature tank 4, so that the high-temperature oil fills the high-temperature tank 4, and the high-temperature oil transfers the heat to the tire tread through the half mold 2 for high-temperature vulcanization. At the same time, the high-temperature oil flows into the annular cavity 6 through the first connecting hole 7. At the same time, the cold oil tank 11 provides cold oil to the annular cavity 6 through the third support tube 16 to neutralize the heat of the high-temperature oil, so that appropriate heat can be provided according to the thickness of each part of the tire, avoiding excess energy when the tire is vulcanized. When the vulcanization is completed, The cold oil tank 11 supplies oil to the low-temperature tank 5 through the first support pipe 14 to accelerate the cooling of the mold and the tire. At the same time, the heat of the mold and the tire is recovered and then refluxed to the cold oil tank 11 through the third support pipe 16 to preserve the heat. When the hot oil tank 10 needs to be heated and provided with heat later, the low-temperature oil in the cold oil tank 11 is introduced into the hot oil tank 10 through the reflux pipe 38. Since the oil in the cold oil tank 11 absorbs heat and its temperature is higher than normal temperature, when heating the oil, it is not necessary to start heating from normal temperature, which reduces the heat required for heating and saves heating energy.

[0041] In the present invention, a moving mechanism 20 for moving the oil bag 18 is provided on the cold oil tank 11. It is worth mentioning that the moving mechanism 20 includes a disc 28 fixedly connected to the right end of the oil bag 18, and a moving screw 29 is threadedly penetrated on the disc 28. The left end of the moving screw 29 is rotationally connected to the half mold 2 on the right side, and the right end of the moving screw 29 is rotationally connected to the cold oil tank 11. A second motor 30 is fixedly installed on the cold oil tank 11, and the driving shaft of the second motor 30 is connected to one of the moving screws 29 through a bevel gear set 31. It is worth mentioning that Yes, the bevel gear set 31 includes a first bevel gear 33 and a second bevel gear 34 that mesh with each other. The first bevel gear 33 is coaxially fixedly connected to the driving shaft of the second motor 30, and the second bevel gear 34 is coaxially fixedly connected to the moving screw 29. The two moving screws 29 are connected by a gear set 32. Further, the gear set 32 ​​includes two gears 35, and the two gears 35 are coaxially fixedly connected to the two moving screws 29 respectively. A transmission ring 36 is rotatably connected to the cold oil tank 11, and the transmission ring 36 is provided with annular tooth grooves that mesh with both gears 35.

[0042] Through the above technical features, while the tire mold is being opened, the second motor 30 drives one of the movable screws 29 to rotate, and one of the movable screws 29 drives the other movable screw 29 to rotate through two gears 35 and a transmission ring 36. The two movable screws 29 drive the disc 28 to move, and the disc 28 drives the oil bag 18 to move until it reaches a suitable position. The mold opening is completed, and the tire with internal vulcanization completed can be taken out, which makes the opening and closing of the tire mold more convenient.

[0043] Working principle:

[0044] Tire vulcanization: When vulcanizing the tire, the hot oil tank 10 provides high-temperature oil to the high-temperature tank 4, so that the high-temperature oil fills the high-temperature tank 4, and the high-temperature oil conducts heat to the tire tread through the half mold 2 for high-temperature vulcanization. At the same time, the high-temperature oil flows into the annular cavity 6 through the first connecting hole 7. At the same time, the cold oil tank 11 provides cold oil to the annular cavity 6 through the third support tube 16 to neutralize the heat of the high-temperature oil, so as to provide appropriate heat according to the thickness of each part of the tire, avoid excess energy when vulcanizing the tire, and when the vulcanization is completed, the cold oil tank 11 is used to cool the tire tread. The oil tank 11 supplies oil to the low-temperature tank 5 through the first support pipe 14 to accelerate the cooling of the mold and the tire. At the same time, the heat of the mold and the tire is recovered and then refluxed to the cold oil tank 11 through the third support pipe 16 to store the heat. When the hot oil tank 10 needs to be heated and provided with heat later, the low-temperature oil in the cold oil tank 11 is introduced into the hot oil tank 10 through the reflux pipe 38. Since the oil in the cold oil tank 11 absorbs heat and its temperature is higher than normal temperature, when heating the oil, it is not necessary to start heating from normal temperature, which reduces the heat required for heating and saves heating energy.

[0045] Mold opening: The two rotating shafts 24 are driven to rotate by the first motor 27, and the two rotating shafts 24 drive the two driving gears 26 to rotate, and the two driving gears 26 drive the ring 23 to rotate, and the ring 23 drives the half mold 2 to move through the multiple rotating keys 22. In the process of mold closing, the multiple rotating keys 22 are applied with force at the same time through the rotation of the ring 23, and the multiple rotating keys 22 can apply pressure to the half mold 2 at the same time. When the mold is closed, each part of the half mold 2 is subjected to the same force, and the force is more uniform. At the same time, since the upper side of the ring 23 is directly Against the hot oil tank 10, the stress of each part of the ring 23 is the same, and there will be no deformation caused by uneven stress of the parts. At the same time, the second motor 30 drives one of the movable screws 29 to rotate, and one of the movable screws 29 drives the other movable screw 29 to rotate through two gears 35 and a transmission ring 36. The two movable screws 29 drive the disc 28 to move, and the disc 28 drives the oil bag 18 to move until it is in a suitable position. The mold can be opened and the tire with internal vulcanization completed can be taken out, which is more convenient for opening and closing the tire mold.
