[0021] The present invention will be further described in detail below with reference to embodiments:

[0022] Example 1

[0023] like Figures 1-4 As shown, this utility model provides a production mold for electrical insulation components, including a buffer mechanism. An upper mold is provided at the top of the inner cavity of the buffer mechanism, and a lower mold is provided at the bottom of the inner cavity of the buffer mechanism. The structure of the lower mold is the same as that of the upper mold. The upper mold includes a mold mechanism, and an air-cooling mechanism is provided inside the mold mechanism. The mold mechanism includes a mounting component 21. An electrical insulation component injection mold core 22 is provided on the inner wall of the mounting component 21. A liquid cooling flow channel 23 is opened inside the mounting component 21. A guide plate 24 is provided on the inner wall of the liquid cooling flow channel 23. A flow pipe 25 is provided on one side of the inner cavity of the liquid cooling flow channel 23. An injection pipe 26 is provided on the top of the mounting component 21. One end of the injection pipe 26 is connected to the interior of the electrical insulation component injection mold core 22.

[0024] In this embodiment, the raw material is injected into the injection mold core 22 of the electrical insulation component through the injection tube 26, and solidified. During the solidification process, coolant is continuously injected into the mounting part 21 through the flow tube 25. The mounting part 21 is cooled by direct contact between the coolant and the mounting part 21. At the same time, the guide plate 24 allows the coolant to advance in an arc shape in the liquid cooling flow channel 23, prolonging the flow time of the coolant in the liquid cooling flow channel 23 and enhancing the cooling effect.

[0025] Example 2

[0026] like Figures 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, an upper mold is provided at the top of the inner cavity of the buffer mechanism, and a lower mold is provided at the bottom of the inner cavity of the buffer mechanism. The upper mold includes a mold mechanism, and an air-cooling mechanism is provided inside the mold mechanism. The mold mechanism includes a mounting component 21, and an electrical insulation component injection mold core 22 is provided on the inner wall of the mounting component 21. A liquid cooling flow channel 23 is opened inside the mounting component 21, and a guide plate 24 is provided on the inner wall of the liquid cooling flow channel 23. A flow pipe 2 is provided on one side of the inner cavity of the liquid cooling flow channel 23. 5. An injection tube 26 is provided on the top of the mounting component 21. One end of the injection tube 26 is connected to the interior of the injection mold core 22 of the electrical insulation component. The air-cooling mechanism includes a heat sink 31. Both ends of the heat sink 31 are fixedly connected to the inner wall of the mounting component 21. Heat sink fins 32 are fixedly connected to the surface of the heat sink 31. The air-cooling mechanism also includes a mounting frame 33. A mounting plate 34 is fixedly connected to the inner wall of the mounting frame 33. A motor 35 is fixedly connected to one side of the mounting plate 34. A fan blade 36 is fixedly connected to one end of the shaft of the motor 35. A dustproof net 37 is provided on one side of the mounting frame 33.

[0027] In this embodiment, the residual heat in the mounting component 21 after liquid cooling is absorbed by the heat sink 31. Then, the contact area with the air is increased by the heat sink fins 32. Under the action of the fan blades 36 driven by the motor 35, the outside air enters the mounting component 21 through the dustproof net 37 and contacts the surface of the heat sink 31 to cool it down, improve the heat dissipation effect, and speed up the molding speed of the electrical insulation component. After molding is completed, the upper fixing plate 14 is moved upward by the external drive component to complete the mold opening and take out the workpiece. Compared with conventional natural heat dissipation, the air-cooled liquid cooling method has a better heat dissipation effect and a faster molding speed of the electrical insulation component.

[0028] Example 3

[0029] like Figures 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the buffer mechanism includes a lower fixed plate 11, the top of the lower fixed plate 11 is fixedly connected to the bottom of the lower mold, a damper 12 is fixedly connected to the top of the lower fixed plate 11, an upper fixed plate 14 is fixedly connected to the top of the damper 12, the bottom of the upper fixed plate 14 is fixedly connected to the top of the upper mold, and a spring 13 is movably sleeved on the surface of the damper 12.

[0030] In this embodiment, during use, the upper fixed plate 14 is driven to move downward by an external power component. During the downward movement, the damper 12 and spring 13 are continuously compressed. The reaction force of the damper 12 and spring 13 buffers the downward movement speed of the upper fixed plate 14, avoiding excessively fast mold closing speed and causing violent collision between the upper and lower molds.

[0031] The working principle of the production mold for this electrical insulation component will be explained in detail below.

[0032] like Figures 1-4As shown, during use, the upper fixed plate 14 is driven downward by an external power component. During the downward movement, the damper 12 and spring 13 are continuously compressed. The reaction force of the damper 12 and spring 13 buffers the downward movement speed of the upper fixed plate 14, preventing the upper and lower molds from colliding violently due to excessively fast mold closing speed. Subsequently, the raw material is injected into the injection mold core 22 of the electrical insulation component through the injection tube 26, allowing it to solidify and form. During solidification, coolant is continuously injected into the mounting part 21 through the flow tube 25. The direct contact between the coolant and the mounting part 21 cools the mounting part 21. At the same time, the guide plate 24 allows the coolant to advance in an arc shape in the liquid cooling flow channel 23, extending the coolant's flow time. The flow time within the liquid cooling circulation channel 23 enhances the cooling effect. Simultaneously, under the action of the heat dissipation plate 31, the residual heat in the mounting part 21 after liquid cooling is absorbed. Subsequently, under the action of the heat dissipation fins 32, the contact area with air is increased. Under the action of the fan blades 36 driven by the motor 35, outside air is allowed to enter the mounting part 21 through the dustproof net 37 and come into contact with the surface of the heat dissipation plate 31 to cool it down, improve the heat dissipation effect, and accelerate the molding speed of the electrical insulation component. After molding is completed, the upper fixing plate 14 is moved upward by the external drive component to complete the mold opening and remove the workpiece. Compared with conventional natural heat dissipation, the air-cooled assisted liquid cooling method has a better heat dissipation effect and a faster molding speed of the electrical insulation component.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
