When the rubber sleeve raw material enters the glue injection tube 33 under the action of external pressure, the rubber sleeve raw material is injected into the mold cavity from the glue injection tube 33 under the push of the pressure difference, and the corners around the upper mold body 31 are fixedly connected with top springs 32; the water-cooling component 6 includes a water storage shell 61, the inner walls on both sides of the water storage shell 61 are fixedly connected with connecting plates 63, the bottom of the water storage shell 61 is fixedly connected with a water outlet 64, and the water outlet 64 is arranged in a linear array along the outer wall of the water storage shell 61, and the inner wall of the water storage shell 61 is fixedly connected with a water inlet pipe 62.

[0020] A sealing ring 35 is fixedly connected to the bottom of the upper mold body 31, and the sealing ring 35 is arranged in a linear array along the outer wall of the upper mold body 31. The sealing ring 35 forms a sealing structure between the two, and uses the elastic deformation of materials such as rubber to fill possible gaps to prevent the rubber sleeve raw material from leaking during high-pressure injection.

A through groove 66 is opened in the wall of the cooling plate 65. The design of the through groove 66 increases the contact area between the coolant and the rubber sleeve cavity.

The through groove 66 is arranged in a linear array along the outer wall of the cooling plate 65, and the outer wall of the cooling plate 65 is fixedly connected to the inner wall of the water storage shell 61.

[0022] The mounting assembly 5 includes a lower mold body 51, an inner wall of the lower mold body 51 is fixedly mounted with a mounting block 55 through a mounting groove 52, and the mounting grooves 52 are arranged in a linear array along the outer wall of the lower mold body 51, coolant is injected into the mounting grooves 52, and the outer wall of the mounting block 55 is fixedly connected with a rubber sleeve shell 54, the top of the lower mold body 51 is pressed and sealed with the bottom of the upper mold body 31, and the top of the rubber sleeve shell 54 is pressed and sealed with the bottom of the sealing ring 35.

[0023] The air cooling component 7 includes a water tank 76, the outer wall of the water tank 76 is fixedly connected to an air inlet shell 71, the inner wall of the bottom of the air inlet shell 71 is fixedly connected to a fan assembly 72, the air inlet shell 71 is fixedly connected to a wind collecting shell 74 on one side close to the water tank 76, two groups of wind collecting shells 74 are provided, and the outer wall of each group of wind collecting shells 74 is fixedly connected to a main air duct 75, the inner wall of the main air duct 75 is connected to a blowing cone pipe 711 through a pipeline, and the blowing cone pipes 711 are arranged in a linear array along the outer wall of the water tank 76, the top of the water tank 76 is fixedly connected to the bottom of the lower mold body 51, the bottom of the lower mold body 51 is fixedly connected to the top of the blowing cone pipe 711, the outer and inner walls of the blowing cone pipe 711 are fixedly connected to a connecting pipe 77, and the inner wall of the bottom of the blowing cone pipe 711 is provided with an air hole 712. The special shape of the blowing cone pipe 711 makes the flow velocity gradually increase when the air flows in the pipe, and finally from The wind holes 712 arranged in a circular array on the inner wall at the bottom blow out heat, taking away heat and realizing air-cooled auxiliary cooling of the rubber sleeve raw material, and the wind holes 712 are arranged in a circular array along the central axis of the blowing cone 711, and the inner wall of the bottom of the water tank 76 is fixedly connected with a water pump 78, and the water outlet end of the water pump 78 is fixedly connected with a pump pipe 79, and the outer wall of the pump pipe 79 is fixedly connected to the inner wall of the water tank 76, and the inner wall of the top of the water tank 76 is fixedly connected with a water injection pipe 710, and the top of the pump pipe 79 is fixedly connected to the end of the water inlet pipe 62 away from the water storage shell 61. After power is turned on, the fan blades rotate. According to Bernoulli's principle, the rotation of the blades causes a pressure difference in the air, thereby sucking external air into the air inlet shell 71, and an air outlet slot 73 is opened in the wall of the top of the water tank 76. The blowing cone 711 is located outside the water outlet nozzle 64, and the top of the water tank 76 is fixedly connected to the limiting column of the hydraulic component 1.

[0024] The hydraulic component 1 serves as the power source of the entire mold. Based on Pascal's principle, it transmits pressure through the internal hydraulic oil to generate a stable and controllable thrust. Its output end is firmly fixed to the pressure plate 2. When the mold starts working, the internal pressure of the hydraulic component 1 changes, pushing the pressure plate 2 to produce a corresponding displacement.

[0025] The upper mold component 3 is slidably connected to the limit column of the hydraulic component 1 through its outer wall, and slides smoothly downward along the limit column under the push of the pressure plate 2. The core of the upper mold component 3 is the upper mold body 31. The inner wall of the upper mold body 31 is connected to the injection tube 33. When the rubber sleeve raw material enters the injection tube 33 under the action of external pressure, the rubber sleeve raw material is injected into the mold cavity from the injection tube 33 under the push of the pressure difference.

[0026] As the upper mold body 31 moves downward, the rubber sleeve columns 34 arranged in a linear array at its bottom begin to function. The rubber sleeve columns 34 are adapted to the internal structure of the rubber sleeve. In the process of compressing the rubber sleeve raw material, the rubber sleeve raw material is positioned by utilizing the fit of the shape to ensure the accuracy of the internal structure of the rubber sleeve during the molding process. At the same time, pressure is applied to the rubber sleeve raw material to assist its initial molding.

[0027] At the corners around the upper mold body 31, top springs 32 are connected. According to Hooke's law, the top springs 32 play a role of buffering and resetting during the opening and closing process of the mold. When the hydraulic component 1 pushes the upper mold component 3 downward, the top springs 32 are compressed and store elastic potential energy, which alleviates the impact force of the upper mold component 3 during the downward process and ensures the smoothness of the movement. When the mold is opened, the top springs 32 release the stored elastic potential energy to help the upper mold component 3 quickly return to its initial position.

[0028] In addition, a sealing ring 35 arranged in the same linear array is fixedly connected to the bottom of the upper mold body 31. When the mold is closed, the upper mold body 31 and the lower mold component 4 approach each other and are finally pressed together. The sealing ring 35 forms a sealing structure between the two, and uses the elastic deformation of materials such as rubber to fill possible gaps to prevent leakage of the rubber sleeve raw material during high-pressure injection.

[0029] The top of the lower mold part 4 is fixedly connected to the limit column of the hydraulic part 1, and is mainly responsible for cooling the rubber sleeve raw material to promote its solidification and molding. The lower mold part 4 includes an air cooling component 7, a mounting component 5 and a water cooling component 6, and each component works together to achieve efficient cooling.

[0030] The top of the air-cooling component 7 is also fixedly connected to the limiting column of the hydraulic component 1. Its operation is based on the principle that air flow carries away heat. The main body of the air-cooling component 7 is a water tank 76. The outer wall of the water tank 76 is connected to the air inlet shell 71. The fan component 72 is installed on the inner wall of the bottom of the air inlet shell 71. When powered on, the fan blades rotate. According to Bernoulli's principle, the rotation of the blades causes a pressure difference in the air, thereby sucking external air into the air inlet shell 71.

[0031] The air entering the air inlet shell 71 is guided to the two groups of air collecting shells 74 on one side close to the water tank 76. The air collecting shells 74 gather and guide the airflow, and collect the scattered air. Then, the air is transported to the blowing cone tubes 711 arranged in a linear array along the outer wall of the water tank 76 through the main air duct 75 connected to the outer wall of the air collecting shell 74. The blowing cone tubes 711 are connected by connecting tubes 77. The special shape of the blowing cone tube 711 makes the flow rate gradually increase when the air flows in the tube, and finally blown out from the wind holes 712 arranged in a circular array on the inner wall of the bottom, taking away the heat, thereby realizing air-cooled auxiliary cooling of the rubber sleeve raw material.

[0032] The mounting assembly 5 connected to the top of the air-cooling assembly 7 is composed of a lower mold body 51, a mounting groove 52, a mounting block 55 and a rubber sleeve shell 54. The inner wall of the lower mold body 51 is provided with mounting grooves 52 arranged in a linear array. The design of the mounting grooves 52 enables the mounting blocks 55 to be firmly fixed therein through a specific threaded connection method. The outer wall of the mounting block 55 is connected to the rubber sleeve shell 54. This structural design enables the mounting assembly 5 to be flexibly installed according to the requirements of rubber sleeve cavities of different sizes by replacing mounting blocks 55 and rubber sleeve shells 54 of different specifications, thereby greatly enhancing the versatility of the mold.

[0033] At the same time, coolant is injected into the mounting groove 52. The coolant in the mounting groove 52 exchanges heat with the rubber sleeve shell 54 by heat conduction, thereby assisting the cooling of the rubber sleeve material in the rubber sleeve shell 54. The top of the lower mold body 51 and the bottom of the upper mold body 31 are pressed and sealed, and the top of the rubber sleeve shell 54 and the bottom of the sealing ring 35 are pressed and sealed, thereby ensuring the sealing of the inside of the mold during the cooling process, preventing leakage of coolant and overflow of rubber sleeve material, and ensuring the stability and reliability of the cooling process.

[0034] The water-cooling component 6 connected to the inner wall of the top of the mounting component 5 has a water storage shell 61 as the main structure. The inner walls on both sides of the water storage shell 61 are connected to the connecting plate 63, and the outer walls on both sides of the connecting plate 63 are connected to the cooling plate 65. A through groove 66 is provided in the wall of the cooling plate 65. The design of the through groove 66 increases the contact area between the coolant and the rubber sleeve cavity. According to the principle of heat transfer, a larger contact area can improve the heat exchange efficiency, so that the coolant can more fully absorb the heat emitted by the rubber sleeve material.

[0035] The inner wall of the water storage shell 61 is connected to the water inlet pipe 62, and the bottom is connected to the water outlet nozzle 64 arranged in a linear array. The water pump 78 on the inner wall of the bottom of the water tank 76 first needs to inject cooling water into the water tank 76 through the water injection pipe 710. It should be noted that the cooling water needs to be located below the air outlet slot 73 and cannot exceed the air outlet slot 73. Based on the principle of centrifugal force, when the impeller of the water pump 78 rotates, the liquid at the center of the impeller is thrown to the surroundings to form a low-pressure area. The water in the water tank 76 is sucked into the center of the impeller, and then the water is transported to the water inlet pipe 62 through the pump pipe 79. The coolant flows in the water storage shell 61, exchanges heat with the rubber sleeve cavity, and then flows out from the water outlet nozzle 64 to complete a water cooling cycle, continuously taking away the heat of the rubber sleeve raw material and accelerating its cooling and molding.

[0036] The blowing cone tube 711 in the air cooling component 7 is located outside the water outlet nozzle 64, wrapping the water outlet nozzle 64 inside. When the water outlet nozzle 64 is in the process of discharging water, a high-speed airflow is continuously blown out through the wind hole 712 at the bottom of the blowing cone tube 711, thereby cooling the downward-flowing water. The high-speed airflow that continues to blow downward continues to blow downward, further cooling the circulating water in the water tank 76, assisting in cooling the circulating water in the water tank 76, and the wind after cooling the circulating water is discharged through the air outlet slot 73.
