[0030] Please refer to Figure 1-8, the present invention provides a technical solution: a rubber sleeve injection mold for the production of an automotive engine ignition coil, comprising: a hydraulic component 1, the output end of the hydraulic component 1 is fixedly connected with a pressing plate 2; an upper mold component 3, the inner wall of the upper mold component 3 is slidably connected with the limit column of the hydraulic component 1, and the upper mold component 3 is used to press down the injected rubber sleeve raw material by sliding; a lower mold component 4, the top of the lower mold component 4 is fixedly connected with the limit column of the hydraulic component 1, and the lower mold component 4 is used to reduce the temperature of the rubber sleeve raw material through heat exchange.

The top of the air-cooling component 7 is fixedly connected with a mounting component 5, and the mounting component 5 is used to mount rubber sleeve cavities of different sizes. The inner wall of the top of the mounting component 5 is fixedly connected with a water-cooling component 6, and the water-cooling component 6 is used to perform heat exchange with the rubber sleeve cavity through a liquid; the upper mold component 3 includes an upper mold body 31, the bottom of the upper mold body 31 is fixedly connected with rubber sleeve columns 34, and the rubber sleeve columns 34 are linearly arranged along the outer wall of the upper mold body 31. The inner wall of the upper mold body 31 is fixedly connected with a rubber injection pipe 33. Inside the inner wall of the upper mold body 31, the rubber injection pipe 33 is connected. When the rubber sleeve raw material enters the rubber injection pipe 33 under the action of external pressure, the rubber sleeve raw material is pushed by the pressure difference and injected into the mold cavity from the rubber injection pipe 33. At the corners around the upper mold body 31, top springs 32 are fixedly connected; 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 water outlet nozzles 64, and the water outlet nozzles 64 are linearly arranged along the outer wall of the water storage shell 61.

[0031] A sealing ring 35 is fixedly connected to the bottom of the upper mold body 31, and the sealing ring 35 is linearly arranged 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 the high-pressure injection process. The sealing ring 35 is used to seal when pressed against the lower mold component 4 to prevent the rubber sleeve raw material from leaking; one side of the top spring 32 away from the upper mold body 31 is fixedly connected to the bottom of the pressing plate 2, the bottom of the pressing plate 2 is in contact with the top of the upper mold body 31, and the inner walls around the upper mold body 31 are slidably connected with the limit columns of the hydraulic component 1.
[0032] Cooling plates 65 are fixedly connected to the outer walls on both sides of the connecting plate 63, and the cooling plates 65 are linearly arranged along the outer wall of the cooling plate 65. Through grooves 66 are formed in the walls of the cooling plates 65. The design of the through grooves 66 increases the contact area between the cooling liquid and the rubber sleeve cavity.

Moreover, the through grooves 66 are linearly arranged 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.
[0033] The mounting assembly 5 includes a lower die body 51. An installation block 55 is fixedly installed on the inner wall of the lower die body 51 through an installation groove 52, and the installation grooves 52 are linearly arrayed along the outer wall of the lower die body 51. A coolant is injected into the installation grooves 52. An outer wall of the installation block 55 is fixedly connected to a rubber sleeve housing 54. The top of the lower die body 51 is press-fitted and sealed with the bottom of the upper die body 31, and the top of the rubber sleeve housing 54 is press-fitted and sealed with the bottom of the sealing ring 35.
[0034] The air-cooling assembly 7 includes a water tank 76. An air inlet housing 71 is fixedly connected to the outer wall of the water tank 76. A fan assembly 72 is fixedly connected to the inner wall of the bottom of the air inlet housing 71. An air collecting housing 74 is fixedly connected to one side of the air inlet housing 71 close to the water tank 76. There are two groups of the air collecting housings 74, and a main air duct 75 is fixedly connected to the outer wall of each group of air collecting housings 74. An air blowing tapered pipe 711 is connected to the inner wall of the main air duct 75 through a pipe, and the air blowing tapered pipes 711 are linearly arrayed 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 die body 51, and the bottom of the lower die body 51 is fixedly connected to the top of the air blowing tapered pipe 711. A connecting pipe 77 is fixedly connected to the inner wall of the outer wall of the air blowing tapered pipe 711. Air holes 712 are formed in the inner wall of the bottom of the air blowing tapered pipe 711. The special shape of the air blowing tapered pipe 711 causes the flow rate of air to gradually increase when flowing in the pipe, and finally blows out from the air holes 712 arrayed in a ring shape on the inner wall of its bottom, taking away heat, realizing air-cooling auxiliary cooling of the rubber sleeve raw material, and the air holes 712 are arrayed in a ring shape along the central axis of the air blowing tapered pipe 711. A water pump 78 is fixedly connected to the inner wall of the bottom of the water tank 76. A pump water pipe 79 is fixedly connected to the water outlet end of the water pump 78, and the outer wall of the pump water pipe 79 is fixedly connected to the inner wall of the water tank 76. A water injection pipe 710 is fixedly connected to the inner wall of the top of the water tank 76. The top of the pump water pipe 79 is fixedly connected to one end of the water inlet pipe 62 far away from the water storage housing 61. After being powered on, the fan blades rotate. According to Bernoulli's principle, the rotation of the blades generates a pressure difference in the air, thereby sucking external air into the air inlet housing 71. An air outlet groove 73 is formed in the top wall of the water tank 76. The air blowing tapered pipe 711 is located outside the water outlet nozzle 64. The top of the water tank 76 is fixedly connected to the limit post of the hydraulic component 1.
[0035] As the power source of the entire mold, the hydraulic component 1 transmits pressure through the internal hydraulic oil according to Pascal's principle, generating a stable and controllable thrust. Its output end is firmly fixed to the pressing plate 2. When the mold starts to work, the internal pressure of the hydraulic component 1 changes, pushing the pressing plate 2 to generate a corresponding displacement.
[0036] The upper die component 3 is slidably connected to the limit posts of the hydraulic component 1 through its outer wall, and smoothly slides downward along the limit posts under the push of the pressure plate 2. The core of the upper die component 3 is the upper die body 31. Inside the inner wall of the upper die body 31, a glue injection tube 33 is connected. 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.
[0037] As the upper die body 31 descends, the rubber sleeve columns 34 arranged in a linear array at its bottom start to play a role. The rubber sleeve columns 34 are adapted to the internal structure of the rubber sleeve. During the process of pressing the rubber sleeve raw material, the shape fit is used to position the rubber sleeve raw material, ensuring the accuracy of the internal structure of the rubber sleeve during the forming process. At the same time, pressure is applied to the rubber sleeve raw material to assist its preliminary forming.
[0038] At the corners around the upper die body 31, top springs 32 are connected. According to Hooke's law, the top springs 32 play a role in buffering and resetting during the mold opening and closing process. When the hydraulic component 1 pushes the upper die component 3 downward, the top springs 32 are compressed, storing elastic potential energy, relieving the impact force during the downward movement of the upper die component 3, and ensuring the smoothness of the movement. When the mold is opened, the top springs 32 release the stored elastic potential energy to help the upper die component 3 quickly reset to the initial position.
[0039] In addition, a sealing ring 35 arranged in a linear array is also fixedly connected to the bottom of the upper die body 31. When the mold is closed, the upper die body 31 and the lower die component 4 approach each other and finally press together. The sealing ring 35 forms a sealing structure between the two, using the elastic deformation of materials such as rubber to fill the possible gaps and prevent the rubber sleeve raw material from leaking during the high-pressure injection process.
[0040] The top of the lower die component 4 is fixedly connected to the limit posts of the hydraulic component 1, and is mainly responsible for cooling the rubber sleeve raw material to promote its solidification and forming. The lower die component 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.
[0041] The top of the air-cooling component 7 is also fixedly connected to the limit posts of the hydraulic component 1. Its work is based on the principle that heat is carried away by air flow. 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 an air inlet shell 71. A fan assembly 72 is installed on the inner wall of the bottom of the air inlet shell 71. After being 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.
[0042] The air entering the air inlet housing 71 is guided to two groups of air collecting housings 74 near one side of the water tank 76. The air collecting housings 74 play a role in gathering and guiding the air flow, collecting the scattered air. Subsequently, the air is conveyed through the main air duct 75 connected to the outer wall of the air collecting housing 74 to the blowing cone pipes 711 arranged in a linear array along the outer wall of the water tank 76. The blowing cone pipes 711 are connected by connecting pipes 77. The special shape of the blowing cone pipes 711 causes the air flow rate to gradually increase when flowing inside the pipes, and finally blows out from the air holes 712 arranged in an annular array on the inner wall of its bottom, taking away heat and realizing the air-cooling assisted cooling of the rubber sleeve raw material.
[0043] The mounting component 5 connected to the top of the air-cooling component 7 is composed of a lower die body 51, mounting grooves 52, mounting blocks 55 and a rubber sleeve housing 54. The inner wall of the lower die 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 blocks 55 is connected to the rubber sleeve housing 54. This structural design enables the mounting component 5 to be flexibly mounted according to the requirements of rubber sleeve cavities of different sizes by replacing mounting blocks 55 and rubber sleeve housings 54 of different specifications, greatly enhancing the versatility of the mold.
[0044] Meanwhile, the mounting grooves 52 are filled with a coolant. The coolant in the mounting grooves 52 exchanges heat with the rubber sleeve housing 54 through heat conduction to assist in cooling the rubber sleeve raw material inside the rubber sleeve housing 54. The top of the lower die body 51 is press-fitted and sealed with the bottom of the upper die body 31, and the top of the rubber sleeve housing 54 is press-fitted and sealed with the bottom of the sealing ring 35 to ensure the sealing performance inside the mold during the cooling process, prevent the leakage of the coolant and the overflow of the rubber sleeve raw material, and ensure the stability and reliability of the cooling process.
[0045] The water-cooling component 6 connected to the inner wall of the top of the mounting component 5 has a water storage housing 61 as the main structure. The two inner walls of the water storage housing 61 are connected with connecting plates 63, and the two outer walls of the connecting plates 63 are further connected with cooling plates 65. Through grooves 66 are opened in the walls of the cooling plates 65. The design of the through grooves 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, enabling the coolant to more fully absorb the heat dissipated by the rubber sleeve raw material.
[0046] 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 nozzles 64 arranged in a linear array. For the water pump 78 on the inner wall of the bottom of the water tank 76, first, cooling water needs to be injected into the water tank 76 through the water injection pipe 710. It should be noted that the cooling water needs to be below the air outlet groove 73 and should not exceed the air outlet groove 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, forming 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 water 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, completing a water cooling cycle, continuously taking away the heat of the rubber sleeve raw material and accelerating its cooling and forming.
[0047] Moreover, the blowing cone pipe 711 in the air cooling component 7 is located outside the water outlet nozzle 64 and wraps the water outlet nozzle 64. When the water outlet nozzle 64 is discharging water, high-speed airflows continuously blown out through the air holes 712 at the bottom of the blowing cone pipe 711 are used to cool the downward flowing water. The continuously downward blowing high-speed airflows continue to blow downward, further performing air cooling on the circulating water in the water tank 76, assisting the circulating water in the water tank 76 in the cooling work. The air after cooling the circulating water is discharged through the air outlet groove 73.
