[0002] In the manufacturing process of tires, after the tires are formed, they need to be vulcanized to make them have the required hardness, strength, elasticity and other performance. Vulcanization is one of the main processes in tire processing. When vulcanizing tires, the rubber of the tires undergoes a series of complex chemical changes to obtain more complete physical, mechanical and chemical properties.

[0003] In the prior art, after vulcanization, the tire needs to be left in the vulcanizing device for a period of time to cool before it can be taken out. The cooling and shaping speed of the tire is slow, which directly affects the production efficiency of tire manufacturing. Utility Model Content

[0008] In the working state, the first mold and the second mold are arranged in a close relationship, the vulcanization cavity is arranged circumferentially around the first accommodating cavity, and is used for high-temperature steam to enter the vulcanization cavity to vulcanize the tire to be vulcanized, and the heat dissipation part is communicated with the vulcanization cavity, and is used for discharging the high-temperature steam out of the vulcanization cavity;

[0009] In the non-working state, the first mold and the second mold are spaced apart along the first direction, and the vulcanization cavity and the first accommodating cavity are spaced apart;

[0010] A cooling device is connected to the vulcanization chamber. In the working state, the cooling device is used to provide cold air to the vulcanization chamber after the high-temperature steam is discharged.

[0011] With the above technical solution, in the working state, the first mold and the second mold are arranged in affixed relation, and the tire to be vulcanized is vulcanized through the vulcanization chamber. After the vulcanization is completed, the high-temperature steam is discharged from the vulcanization chamber, and then cold air is provided to the vulcanization chamber through the cooling device to achieve rapid cooling of the vulcanized tire. When the tire is cooled, the vulcanization device is switched to the non-working state, and at this time, the first mold and the second mold are arranged at intervals along the first direction, so as to facilitate timely removal of the tire and effectively improve the production efficiency of tire manufacturing.

[0012] According to another specific embodiment of the utility model, the embodiment of the utility model discloses a vulcanization device, wherein the cooling device includes a cooling chamber and an evaporation chamber, wherein the evaporation chamber is arranged on one side of the cooling chamber, and the evaporation chamber is communicated with the cooling chamber, wherein the cooling chamber is used to generate a liquid condensing agent, wherein the liquid condensing agent evaporates in the evaporation chamber to generate the cold air, and the evaporation chamber is communicated with the vulcanization chamber to provide the cold air to the vulcanization chamber after the high-temperature steam is discharged.

[0013] By adopting the above technical scheme, the liquid condensing agent produced by the cooling chamber is evaporated in the evaporation chamber to generate cold air and the cold air is passed into the vulcanization chamber. Since the cooling chamber and the evaporation chamber are set up, the condensing agent only needs to absorb the heat in the evaporation chamber to generate cold air, which can improve the production efficiency of cold air.

[0015] By adopting the above technical scheme, the low-temperature and low-pressure gaseous condensing agent is compressed into a high-temperature and high-pressure gaseous condensing agent through a compressor, and then the high-temperature and high-pressure gaseous condensing agent enters the condenser, and part of the gaseous condensing agent becomes liquid condensing agent after condensation, and finally the liquid condensing agent evaporates in the evaporation chamber to generate cold air, so that cold air can be provided at a relatively low cost for cooling the tires after vulcanization treatment.

[0017] By adopting the above technical scheme, the high-temperature and high-pressure gaseous condensing agent formed by the compressor first enters the first condenser, and the medium-temperature liquid condensing agent is obtained after condensation treatment. Then, the medium-temperature liquid condensing agent is evaporated and cooled through the second condenser, and finally a low-temperature liquid condensing agent is obtained. The liquid condensing agent obtained by this scheme has a lower temperature and is easy to evaporate and absorb heat in the evaporation chamber, thereby further improving the production efficiency of cold air.

[0019] By adopting the above technical solution, an evaporator is provided in the evaporation chamber, and the liquid condensing agent is evaporated into gaseous condensing agent by the evaporator. On the one hand, the heat in the evaporation chamber is taken away by evaporation to form cold air. On the other hand, the gaseous condensing agent formed after evaporation can be returned to the compressor for recycling.

[0021] By adopting the above technical solution, the heat can be dissipated from the first condenser tube through the heat sink, so as to realize the condensation process of the high-temperature and high-pressure gaseous condensing agent.

[0022] According to another specific embodiment of the utility model, the embodiment of the utility model discloses a vulcanization device, wherein the cooling device includes a fan and a grille, wherein the grille covers an open end of a cooling chamber and is used to connect the cooling chamber with an external environment, and the fan is disposed on a side of the cooling chamber close to the grille and is used to discharge heat from the cooling chamber into the external environment.

[0040] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] In some embodiments, see Figure 1 , Figure 2The present application provides a vulcanization system, including a vulcanization device 10 and a tire 20, wherein the vulcanization device has a working state and a non-working state. In the working state, the tire 20 is placed in the vulcanization device 10 for vulcanization and cooling treatment; in the non-working state, the tire 20 can be taken out of the vulcanization device 10 or a new tire to be treated can be placed. Exemplarily, before the tire 20 is placed in the vulcanization device 10 for vulcanization treatment, it is necessary to cover the inner side of the tire 20 with a vulcanizing agent, and the inner side of the tire refers to the side of the tire that is not in contact with the ground. In some embodiments, the vulcanizing agent is sulfur. It is understandable that the vulcanizing agent can also select organic peroxides such as tert-butyl peroxide (TBPB) and other types of vulcanizing agents. The present application does not limit the specific selection of the vulcanizing agent.

[0042] In some embodiments, see Figure 1 , Figure 2 , Figure 3 The vulcanization device 10 includes a first mold 11, a second mold 12 and a cooling device 13. In a working state, the second mold 12 can move toward the first mold 11 along a first direction X until the first mold 11 and the second mold 12 are fitted together. In a non-working state, the second mold 12 can move away from the first mold 11 along the first direction X, and finally the first mold 11 and the second mold 12 are spaced apart along the first direction X.

[0043] Exemplarily, the first mold 11 includes a first accommodating cavity 111, and the first accommodating cavity 111 is used to place the tire 20 to be vulcanized; the second mold 12 is used to reciprocate along the first direction X, so that the vulcanization device 10 switches between the working state and the non-working state. Along the first direction X, the second mold 12 is arranged on one side of the first mold 11, and the second mold 12 includes a vulcanization cavity 121 and a heat dissipation portion 122. In the non-working state, the vulcanization cavity 121 is spaced apart from the first accommodating cavity 111. Exemplarily, the first direction X is a vertical direction.

[0044] In some embodiments, the cooling device 13 is connected to the vulcanization chamber 121. In the working state, the vulcanization chamber 121 is arranged around the first accommodating chamber 111 along the circumferential direction R, and is used to allow high-temperature steam to enter the vulcanization chamber 121 to vulcanize the tire 20 to be vulcanized. The heat dissipation portion 122 is connected to the vulcanization chamber 121, and is used to discharge the high-temperature steam from the vulcanization chamber 121. The cooling device 13 is used to provide cold air to the vulcanization chamber 121 after the high-temperature steam is discharged.

[0045] With the above technical solution, in the working state, the first mold 11 and the second mold 12 are arranged in close contact, and the tire 20 to be vulcanized is vulcanized through the vulcanization chamber 121. After the vulcanization is completed, the high-temperature steam is discharged from the vulcanization chamber 121, and then the cooling device 13 provides cold air to the vulcanization chamber 121 to achieve rapid cooling of the vulcanized tire 20. When the tire 20 is cooled, the vulcanization device 10 is switched to the non-working state. At this time, the first mold 11 and the second mold 12 are spaced apart along the first direction, so as to facilitate timely removal of the tire 20 and effectively improve the production efficiency of the tire 20 manufacturing.

[0046] In some embodiments, see Figure 1 The vulcanization device 10 includes a bottom 14 and a top 15. The bottom 14 and the top 15 are arranged at intervals along the first direction X. The bottom 14 and the top 15 are connected by a plurality of support rods 16, and a working area is formed between the bottom 14 and the top 15. Exemplarily, the bottom 14 and the top 15 are both plate-shaped, and the bottom 14 and the top 15 are both rectangular. The support rods 16 include four support rods 16 arranged opposite to each other in pairs, and the four support rods 16 are respectively arranged at the four corners of the bottom 14 and the top 15. It can be understood that the present application does not limit the shape of the bottom 14 and the top 15, for example, it can also be a cube, and the bottom 14 and the top 15 are not limited to a plate shape. In addition, the number of support rods 16 can also be 3, 5, 6, etc., and the present application does not limit it.

[0047] For example, see Figure 1 , Figure 3 The first mold 11 , the second mold 12 and the cooling device 13 are all arranged in the aforementioned working area, wherein the first mold 11 and the cooling device 13 are arranged at the bottom 14 , and the second mold 12 is arranged at the top 15 . In some embodiments, the top 15 is further provided with a hydraulic press 151, and a piston rod 152 of the hydraulic press 151 is connected to the second mold 12. The piston rod 152 of the hydraulic press 151 can extend or retract along the first direction X. When the piston rod 152 extends toward the first mold 11 along the first direction X, the second mold 12 moves along the first direction X close to the first mold 11 until the first mold 11 fits the second mold 12. At this time, the vulcanization device 10 is in a working state; after the vulcanization and cooling treatment is completed, the piston rod 152 of the hydraulic press 151 retracts along the first direction X away from the first mold 11, so that the second mold 12 moves along the first direction X away from the first mold 11, so that the first mold 11 and the second mold 12 are spaced apart. At this time, the vulcanization device 10 is in a non-working state, which is convenient for the operator to promptly remove the processed tire 20 from the first accommodating cavity 111 and replace it with a new tire 20 to be processed.

[0048] In some embodiments, in order to better fit the tire, the first mold 11 and the second mold 12 are both barrel-shaped. It can be understood that the vulcanization device 10 provided in the present application can also be used for vulcanization of other rubber products. Therefore, the present application does not limit the shapes of the first mold 11 and the second mold 12.

[0049] In some embodiments, see Figure 1 , Figure 3 , the heat dissipation part 122 includes a heat dissipation port 1221 and a top cover 1222, the top cover 1222 is arranged at the heat dissipation port 1221, when the top cover 1222 is opened, the heat dissipation port 1221 is connected to the vulcanization chamber 121 and the external environment, when the vulcanization treatment is completed, there is high-temperature steam in the vulcanization chamber 121, at this time, the top cover 1222 is opened to discharge the high-temperature steam in the vulcanization chamber 121, when the cooling device 13 starts to provide cold air to the vulcanization chamber 121, the top cover 1222 is closed. Exemplarily, the second mold 12 includes an upper pressing plate 123, the upper pressing plate 123 includes a first channel (not shown in the figure), along the first direction X, one end of the first channel is connected to the heat dissipation port 1221, and the other end is connected to the vulcanization chamber 121. It can be understood that in some embodiments, the cooling device may also include an exhaust fan (not shown in the figure), the exhaust fan is connected to the heat dissipation port 1221, and is used to extract the high-temperature steam from the vulcanization chamber 121 to improve work efficiency.

[0050] In some embodiments, along the first direction X, the side of the upper pressing plate 123 close to the top 15 is connected to the piston rod 152, and the side of the upper pressing plate 123 facing away from the top 15 is provided with a vulcanization chamber 121. Exemplarily, the vulcanization chamber 121 is annular, and the upper pressing plate 123 includes a second channel 1231 and a third channel 1232. The second channel 1231 is used to connect the vulcanization chamber 121 and the steam device (not shown in the figure). In the working state, the high-temperature steam generated by the steam device enters the vulcanization chamber 121 through the second channel 1231. The third channel 1232 is used to connect the cooling device 13 and the vulcanization chamber 121. After the high-temperature steam is discharged from the vulcanization chamber 121, the cold air provided by the cooling device 13 enters the vulcanization chamber 121 through the third channel 1232.

[0051] Exemplarily, when the high-temperature steam generated by the steam device enters the vulcanization chamber 121 through the second channel 1231, the third channel 1232 remains closed; when the cold air provided by the cooling device 13 enters the vulcanization chamber 121 through the third channel 1232, the second channel 1231 remains closed. For example, end covers may be provided on the second channel 1231 and the third channel 1232, respectively, for opening or closing the second channel 1231 or the third channel 1232.

[0052] In some embodiments, see Figure 1 , Figure 2 , Figure 3 The second mold 12 includes a vulcanization bladder 124, which is used to expand or contract in the second direction Y in the first accommodating cavity 111. In the working state, the vulcanization bladder 124 expands in the second direction Y to support and fix the tire 20 to be vulcanized, and heat the side of the tire 20 to be vulcanized that is opposite to the vulcanization cavity 121 along the second direction. Exemplarily, along the first direction X, the vulcanization bladder 124 is arranged on the side of the upper pressing plate 123 that is opposite to the top 15, and the vulcanization cavity 121 is arranged around the vulcanization bladder 124 along the circumferential direction R.

[0053] Exemplarily, along the second direction Y, the tire 20 includes a first side 21 and a second side 22. In the working state, the second side 22 is attached to the side wall of the first accommodating cavity 111 provided in the vulcanizing device 10, and the expanded vulcanizing bladder 124 enters the inner side of the tire 20 from the first side 21 to support and fix the tire 20 to be vulcanized. The second direction Y may be the radial direction of the tire 20. It should be noted that Figure 2 FIG. 1 is a schematic diagram showing the position of the tire 20 in the vulcanization device 10 provided in the present application. Figure 2 The tire 20 is only a simplified schematic diagram, and its shape and other related features do not limit the range of tires to which the vulcanization device 10 provided in the present application can be applied.

[0054] In some embodiments, the upper pressure plate 123 includes a fourth channel 1233, one end of the fourth channel 1233 is connected to the sulfide bladder 124, and the other end is connected to a water adding device (not shown in the figure). The water adding device is used to add high-pressure hot water into the sulfide bladder 124 through the fourth channel 1233, so that the sulfide bladder 124 expands along the second direction Y.

[0055] In some embodiments, see Figure 1 , Figure 3 , Figure 4 The first mold 11 includes a first fixing member 113 and a second fixing member 114, and the first fixing member 113 and the second fixing member 114 are used to move toward or away from each other along the second direction Y. In the working state, the first fixing member 113 and the second fixing member 114 enclose a first accommodating cavity 111. Exemplarily, in the working state, the projection of the first fixing member 113 and the second fixing member 114 in the first direction X is circular, and a plurality of protrusions 115 are provided on the side walls of the first fixing member 113 and the second fixing member 114, and the plurality of protrusions 115 are arranged at intervals along the circumferential direction R. Exemplarily, a total of 16 protrusions 115 are provided on the side walls of the first fixing member 113 and the second fixing member 114. It can be understood that the present application does not limit the number of protrusions 115, and it can also be 14, 15, 17, 18, etc.

[0056] In some embodiments, see Figure 4The first mold 11 includes a shell 116 and a second accommodating cavity 117. The side wall of the shell 116 is arranged around the first fixing member 113 and the second fixing member 114 along the circumferential direction R, and the side wall is spaced from the first fixing member 113 and the second fixing member 114 along the second direction Y. The side wall, the first fixing member 113, and the second fixing member 114 jointly form the second accommodating cavity 117. In the working state, the vulcanization cavity 121 is located in the second accommodating cavity 117.

[0057] Exemplarily, a slide groove 1161 is provided at the bottom of the shell 116, and a bidirectional threaded rod 112 is movably inserted into the inner wall of the slide groove 1161. The first fixing member 113 and the second fixing member 114 are respectively arranged on the bidirectional threaded rod 112 through a first connecting block (not shown in the figure) and a second connecting block 1141. By rotating the bidirectional threaded rod 112, the first fixing member 113 and the second fixing member 114 can move toward or away from each other along the second direction Y, so that the processed tire can be removed and replaced with a new tire to be processed, so as to improve work efficiency.

[0058] In some embodiments, a motor 1162 is fixedly installed on one side of the shell 116, and the output end of the motor 1162 is fixedly connected to the bidirectional threaded rod 112, which is used to drive the bidirectional threaded rod 112 to rotate, thereby making the first fixing member 113 and the second fixing member 114 move toward or away from each other along the second direction Y.

[0059] Before the vulcanization device 10 is started, the first fixing member 113 and the second fixing member 114 are moved in opposite directions along the second direction Y by the bidirectional threaded rod 112, so as to facilitate the placement of the tire 20; the first fixing member 113 and the second fixing member 114 are moved in opposite directions along the second direction Y by the bidirectional threaded rod 112, so as to fix the tire 20 in the first accommodating chamber 111, and the vulcanization device 10 is put into working state by the hydraulic press 151. After the vulcanization and cooling treatment is completed, the first fixing member 113 and the second fixing member 114 are moved in opposite directions along the second direction Y by the bidirectional threaded rod 112, so as to facilitate the removal of the tire and the placement of a new tire to be treated.

[0060] In some embodiments, see Figure 1 , Figure 5The cooling device 13 includes a protective shell 130, which is in the shape of a rectangular parallelepiped. For example, the interior of the protective shell 130 is divided into a cooling chamber 131 and an evaporation chamber 132. The evaporation chamber 132 is arranged on one side of the cooling chamber 131, and the evaporation chamber 132 is connected to the cooling chamber 131. The cooling chamber 131 is used to generate a liquid condensing agent, and the liquid condensing agent evaporates in the evaporation chamber 132 to generate cold air. The evaporation chamber 132 is connected to the vulcanization chamber 121, and is used to provide cold air to the vulcanization chamber 121 after the high-temperature steam is discharged. For example, the cooling chamber 131 and the evaporation chamber 132 are both in the shape of a rectangular parallelepiped, so the entire cooling device 13 is roughly in the shape of a rectangular parallelepiped, which is convenient for being arranged in the aforementioned working area.

[0061] It is understandable that the protective shell 130, the cooling chamber 131 and the evaporation chamber 132 may also be other shapes such as a cube, and the present application does not limit this.

[0062] In some embodiments, see Figure 5 The cooling device 13 includes a compressor 133 and a condenser 134, which are connected to each other. The compressor 133 and the condenser 134 are both arranged in the cooling chamber 131. The compressor 133 is used to generate a gaseous condensing agent, and the gaseous condensing agent forms a liquid condensing agent through the condenser 134. Exemplarily, the compressor 133 includes a compression part and a storage part, which are connected to the compression part. The storage part stores a low-temperature and low-pressure gaseous condensing agent, and the low-temperature and low-pressure gaseous condensing agent is compressed into a high-temperature and high-pressure gaseous condensing agent through the compression part. Then, the high-temperature and high-pressure gaseous condensing agent enters the condenser 134, and part of the gaseous condensing agent becomes a liquid condensing agent after condensation. Finally, the liquid condensing agent evaporates in the evaporation chamber 132 to generate cold air, so that cold air can be provided at a lower cost for cooling the tire 20 after vulcanization treatment. Exemplarily, the condensing agent includes Freon. It can be understood that the condensing agent can also be other inorganic compound refrigerants, etc., and this application does not limit this.

[0063] In some embodiments, see Figure 5 The condenser 134 includes a first condenser 1341 and a second condenser 1342. One end of the first condenser 1341 is connected to the compressor 133, and the other end is connected to the second condenser 1342. The diameter of the second condenser 1342 is smaller than the diameter of the first condenser 1341. The gaseous condensing agent passes through the first condenser 1341 and the second condenser 1342 in sequence to form a liquid condensing agent. Exemplarily, the high-temperature and high-pressure gaseous condensing agent formed by the compressor 133 first enters the first condenser 1341, and a medium-temperature liquid condensing agent is obtained after condensation. The medium-temperature liquid condensing agent is then evaporated and cooled through the second condenser 1342, and finally a low-temperature liquid condensing agent is obtained. The liquid condensing agent obtained by this solution has a lower temperature and is easy to evaporate and absorb heat in the evaporation chamber 132, further improving the production efficiency of cold air.

[0064] In some embodiments, see Figure 5 The first condenser 1341 includes a plurality of first vertical portions (not shown) spaced apart along the third direction Z. The first vertical portions extend along the first direction X. Every two first vertical portions are connected by a first arc portion 1343. Two adjacent first arc portions 1343 are disposed on both sides of the first vertical portion along the first direction X. The second condenser 1342 is a capillary tube. For example, the capillary tube includes a copper tube with a diameter of 0.4 to 2.0 mm. The diameter of the first condenser 1341 can be a copper tube of a size of 6, 7, 8 mm, etc. The diameter can be selected according to actual needs. The present application does not limit the diameters of the first condenser 1341 and the second condenser 1342.

[0065] In some embodiments, see Figure 5 The cooling device 13 includes an evaporator 135, which is arranged in the evaporation chamber 132 and is used to evaporate the liquid condensing agent into a gaseous condensing agent. The evaporator 135 includes a first end and a second end. The first end is connected to the second condensing pipe 1342, and the second end is connected to the compressor 133, so that the evaporated gaseous condensing agent flows into the compressor 133. The liquid condensing agent is evaporated into a gaseous condensing agent by the evaporator 135. On the one hand, the heat in the evaporation chamber 132 is taken away by evaporation to form cold air. On the other hand, the gaseous condensing agent formed after evaporation can be returned to the compressor 133 for recycling.

[0066] Exemplarily, the evaporator 135 may be in the form of an evaporation tube. Exemplarily, the evaporation tube includes a plurality of second vertical portions 1351 spaced apart along the third direction Z in the evaporation chamber 132, the second vertical portions 1351 extending along the first direction X, each two second vertical portions 1351 being connected by a second arc portion 1352, and two adjacent arc portions 1343 being arranged on both sides of the second vertical portion 1351 along the first direction X. After the low-temperature liquid condensing agent enters the evaporation tube, it is used to evaporate and absorb the heat in the evaporation chamber 132, so that the air in the evaporation chamber 132 is cooled to form cold air.

[0067] In some embodiments, see Figure 5 The cooling device 13 includes a heat sink 136, and the first condenser tube 1341 is penetrated through the heat sink. The heat sink 136 is used to reduce the temperature of the first condenser tube 1341. Exemplarily, the heat sink 136 extends along the third direction Z, and the heat sink 136 includes a plurality of heat sinks 136, and the plurality of heat sinks 136 are stacked along the first direction X to form a heat sink group. The first vertical portion of the first condenser tube 1341 is penetrated through the heat sink group to improve the condensation effect and efficiency of the first condenser tube 1341.

[0068] In some embodiments, see Figure 5The cooling device 13 includes a fan 137 and a grille 138. The grille 138 covers the open end of the cooling chamber 131 and is used to connect the cooling chamber 131 with the external environment. The fan 137 is provided on the side of the cooling chamber 131 close to the grille 138 and is used to discharge the heat of the cooling chamber 131 into the external environment. Exemplarily, the fan 137 is provided on the side of the heat sink group close to the grille 138 in the second direction Y, and can directly take the heat of the heat sink group out of the cooling chamber 131, thereby improving the condensation efficiency of the condenser 134. Exemplarily, the grille 138 includes a through hole extending along the third direction Z. The grille 138 can connect the cooling chamber 131 with the external environment and provide protection for the fan 137 and the compressor 133. In some embodiments, the number of through holes is 4, and the 4 through holes are arranged at intervals along the first direction X. It can be understood that the number of through holes can also be 3, 5, 6, etc., and the present application does not limit this.

[0069] In some embodiments, a fan 1321 and a connecting pipe 1322 are provided in the evaporation chamber 132 , one end of the connecting pipe 1322 is connected to the fan 1321 , and the other end is connected to the vulcanization chamber 121 , so as to draw the cold air in the evaporation chamber 132 into the vulcanization chamber 121 .

[0070] For ease of understanding, the complete working process of the cooling device provided by the present application will be specifically described below:

[0071] See also Figure 4 , place the tire between the first fixing member 113 and the second fixing member 114, start the motor 1162 to drive the bidirectional threaded rod 112 to rotate, so that the first fixing member 113 and the second fixing member 114 move toward each other along the second direction Y, and then the tire is located in the first accommodating cavity 111 formed by the first fixing member 113 and the second fixing member 114.

[0072] See also Figure 3 , start the hydraulic press 151 to move the upper pressing plate 123 of the second mold 12 along the first direction X toward the first mold 11 until the upper pressing plate 123 is in contact with the housing 116 .

[0073] High-pressure hot water is added into the vulcanization bladder 124 through the fourth channel 1233, so that the vulcanization bladder 124 expands along the radial direction of the tire, so that the tire fills the gap in the first accommodating chamber 111, and then high-temperature steam is added into the vulcanization chamber 121 through the second channel 1231 to achieve vulcanization and shaping of the tire.

[0074] See also Figure 1 , Figure 3 , Figure 5After the shaping is completed, the compressor 133 of the cooling device 13 is started and the top cover 1222 is opened to discharge the heat in the vulcanization chamber 121. The compressor 133 sucks in the low-temperature and low-pressure gaseous condensing agent. Under the action of the compressor 133, a high-temperature and high-pressure gaseous condensing agent is formed. The high-temperature and high-pressure gaseous condensing agent enters the first condensing tube 1341 for cooling and heat dissipation, and part of the gas entering the first condensing tube 1341 will become a medium-temperature liquid condensing agent after condensation. The medium-temperature liquid condensing agent will enter the second condensing tube 1342. Since the second condensing tube 1342 suddenly becomes narrower, when the liquid condensing agent passes through the second condensing tube 1342, the pressure suddenly decreases, causing part of the liquid condensing agent to suddenly evaporate and cool. The cooled liquid condensing agent then passes through the evaporator 135 for evaporation and vaporization. The cooled condensing agent will continuously take away the heat in the evaporation chamber 132 and form cold air.

[0075] The fan 1321 is started to continuously extract cold air from the evaporation chamber 132, and then enters the vulcanization chamber 121 through the third channel 1232 to accelerate the cooling and shaping speed of the tire.

[0076] After cooling, the hydraulic press 151 is started to move the upper pressing plate 123 of the second mold 12 along the first direction X away from the first mold 11, so that the upper pressing plate 123 and the shell 116 are spaced apart in the first direction X to facilitate tire replacement.

[0077] See also Figure 4 , start the motor 1162 to drive the bidirectional threaded rod 112 to rotate, so that the first fixing member 113 and the second fixing member 114 move backwards along the second direction Y, so as to facilitate the removal of the treated tire and the replacement of the new tire to be treated.
