[0002] An injection molding machine, also known as an injection molding machine or an injection machine, is divided into various types such as vertical, horizontal, and all-electric types. An injection molding machine is the main molding equipment for making various shaped plastic products by using a plastic molding die for thermoplastic or thermosetting plastics.

[0003] When using an injection molding machine, usually an electric motor is used to convert electrical energy into mechanical energy, so as to drive the injection molding machine to mix, heat, and melt the raw materials required for injection molding and then form them into finished products through injection molding. Therefore, the electric motor is a very important component in the injection molding machine.

[0004] However, when the injection molding machine is used for a long time, the electric motor may overheat due to a large working load, which may cause damage to the internal components of the electric motor due to heat accumulation, affect the working performance of the electric motor, and even cause delays in the operation of the injection molding machine. Therefore, in view of the above problems, a heat dissipation device for an injection molding machine is proposed. Content of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] As Figure 1 , Figure 2 , Figure 5 shown, a heat dissipation device for an injection molding machine includes an injection molding machine body 1; an injection molding machine electrical box 11 is fixedly connected to the top of the injection molding machine body 1; a motor 12 is rotatably connected to the middle of the injection molding machine electrical box 11; a plurality of groups of connecting plates 17 are fixedly connected to the inner side wall of the injection molding machine electrical box 11; copper fins 16 are fixedly connected to the ends of the connecting plates 17; a plurality of groups of hollow copper tubes 15 are fixedly connected to the middle of the copper fins 16; arc-shaped heat conduction plates 14 are fixedly connected to the ends of the hollow copper tubes 15; a plurality of groups of heat absorption wires 13 are fixedly connected to the middle of the arc-shaped heat conduction plates 14; during operation, a heat conduction liquid is injected into the hollow copper tubes 15. When the injection molding machine body 1 works for a long time, the motor 12 will generate a large amount of heat due to excessive operation. At this time, the heat absorption wires 13 will absorb the heat and transfer it to the hollow copper tubes 15 through the arc-shaped heat conduction plates 14. Then, the heat conduction liquid inside the hollow copper tubes 15 will absorb the heat. When the heat temperature is greater than the evaporation threshold of the heat conduction liquid, it will evaporate into water vapor and adhere to the inner side wall of the hollow copper tubes 15. When the injection molding machine body 1 stops working for a period of time, the temperature inside the hollow copper tubes 15 will tend to be stable. At this time, the heat conduction liquid evaporated into water vapor will converge together inside the hollow copper tubes 15. When the hollow copper tubes 15 absorb heat, the copper fins 16 will absorb a part of the heat at the hollow copper tubes 15. Through the mutual cooperation of the heat absorption wires 13 and the hollow copper tubes 15 in this step, the heat generated during the operation of the motor 12 can be reduced, thereby preventing the mechanical heat deformation caused by excessive heat. In the hydraulic components, thermal expansion will cause the moving parts to jam due to the reduction of their mating clearances, resulting in action failure, affecting the transmission accuracy of the hydraulic system, causing the working quality of the components to deteriorate, and even reducing their working life in severe cases. Through the function of the copper fins 16, a part of the heat can be shared, thereby alleviating the evaporation speed of the heat conduction liquid inside the hollow copper tubes 15.

[0025] As Figure 1 , Figure 2 , Figure 3 , Figure 4 shown, a suction fan 2 is fixedly connected to the side of the injection molding machine electrical box 11; a cross support frame 21 is fixedly connected to the end of the suction fan 2; a rotating shaft 22 is rotatably connected to the middle of the cross support frame 21; a plurality of groups of fan blades 23 are fixedly connected to the middle of the rotating shaft 22; during operation, the cross support frame 21 plays a role in supporting the rotating shaft 22. When the suction fan 2 needs to work, the rotating shaft 22 will rotate in the middle of 212, thereby driving the fan blades 23 to rotate. The rotation of the fan blades 23 will form a certain amount of wind, so that the suction fan 2 can perform the work of heat absorption and ventilation. Through the action of the suction fan 2 in this step, the heat absorbed by the copper fins 16 and the hollow copper tube 15 can be discharged to the outside, thereby assisting the hollow copper tube 15 and the copper fins 16 in heat absorption work, and further strengthening the ventilation and heat dissipation effect inside the injection molding machine electrical box 11.

[0026] As Figure 2 , Figure 5 shown, a limiting plate 3 is fixedly connected to the inner side wall of the injection molding machine electrical box 11; a plurality of groups of spring columns 31 are fixedly connected to the middle of the limiting plate 3; shock pads 32 are fixedly connected to the ends of the spring columns 31; during operation, the limiting plate 3 plays a role in supporting the motor 12. When the motor 12 is working, it will generate vibrations. At this time, the vibrations will be transmitted to the spring columns 31 through the limiting plate 3. The spring columns 31 will perform telescopic work under the influence of the vibrations, so as to relieve a certain amount of vibrations. Then the remaining vibration force will be transmitted to the shock pads 32, and the shock pads 32 can weaken the vibration force once again. Through the mutual cooperation of the spring columns 31 and the shock pads 32 in this step, the vibrations generated during the operation of the motor 12 can be alleviated, helping the motor 12 to be more stable during operation. At the same time, through shock absorption, the noise generated during the operation of the motor 12 can be reduced, thereby reducing noise pollution and providing a relatively good working environment for the staff.

[0027] As Figure 1 shown, a box door 4 is rotatably connected to the top of the injection molding machine electrical box 11; a plurality of groups of hinges 41 are rotatably connected to one side of the box door 4; a handle 42 is fixedly connected to one side of the box door 4; during operation, when it is necessary to open the injection molding machine electrical box 11, the hinges 41 can be first held and pulled outwards, and then the box door 4 can be expanded outwards by using the rotating characteristics of the hinges 41, so as to open the injection molding machine electrical box 11. Through the opening of the box door 4 in this step, it is convenient for the staff to perform maintenance, repair and maintenance work on the components inside the injection molding machine electrical box 11.

[0028] As Figure 3 , Figure 4As shown, multiple groups of strip plates 5 are fixedly connected to the middle of the air suction fan 2; brush hairs 51 are fixedly connected to the middle of each strip plate 5; connecting rings 52 are fixedly connected to the ends of each strip plate 5; during operation, when the fan blades 23 rotate, their surfaces will contact the brush hairs 51, and at this time, the brush hairs 51 can clean the fan blades 23. This step is that when the air suction fan 2 is operating, the dust, impurities, and oil stains inside the injection molding machine electric box 11 will be discharged along with the exhaust air flow. However, a part of the dust will adhere to the surface of the fan blades 23, and in the long-term accumulation, it may cause a situation where the rotation speed of the fan blades 23 is affected. At this time, through the cooperation of the strip plates 5 and the brush hairs 51, the accumulation of dust on the surface of the fan blades 23 can be reduced.

[0029] As Figure 1 shown, a valve plate 6 is fixedly connected to the end of the air suction fan 2; during operation, when the air suction fan 2 is operating, the exhaust air flow will first reach the valve plate 6, and at this time, the valve plate 6 will expand outwards under the influence of the air flow pressure, so as to smoothly discharge the air flow to the outside. This step is that when the air suction fan 2 is not operating, the valve plate 6 will be in a closed state, thereby reducing the possibility that external dust and impurities may enter the inside of the injection molding machine electric box 11 through the air suction fan 2 and cause pollution to the components inside the injection molding machine electric box 11.

[0030] As Figure 1 shown, multiple ventilation holes 7 are opened on one side of the injection molding machine electric box 11; during operation, the opening of the ventilation holes 7 can make the air inside the injection molding machine electric box 11 flow with the outside of the limit plate 3. Through the function of the ventilation holes 7, this step can further strengthen the heat dissipation effect of the inside of the injection molding machine electric box 11, thereby reducing the working load of the air suction fan 2.

[0031] Working principle: During operation, there is heat-conducting liquid injected inside the hollow copper tube 15. When the injection molding machine body 1 works for a long time, the motor 12 will generate a large amount of heat due to excessive operation. At this time, the heat-absorbing wire 13 will absorb the heat and transfer it to the hollow copper tube 15 through the arc-shaped heat-conducting plate 14. Then, the heat-conducting liquid inside the hollow copper tube 15 will absorb the heat. When the heat temperature is greater than the evaporation threshold of the heat-conducting liquid, it will evaporate into water vapor and adhere to the inner side wall of the hollow copper tube 15. After the injection molding machine body 1 stops working for a period of time, the temperature inside the hollow copper tube 15 will tend to be stable. At this time, the heat-conducting liquid evaporated into water vapor will converge inside the hollow copper tube 15. When the hollow copper tube 15 absorbs heat, the copper fins 16 will absorb a part of the heat at the hollow copper tube 15. Through the mutual cooperation of the heat-absorbing wire 13 and the hollow copper tube 15, this step can reduce the heat generated during the operation of the motor 12, thereby preventing thermal deformation of the machine caused by excessive heat. In the hydraulic components, thermal expansion will cause the moving parts to jam due to the reduction of their mating clearances, resulting in malfunction of the actions, affecting the transmission accuracy of the hydraulic system, causing the working quality of the components to deteriorate, and even reducing their working life seriously in severe cases. Through the function of the copper fins 16, a part of the heat can be shared, thereby alleviating the evaporation rate of the heat-conducting liquid inside the hollow copper tube 15. During operation, the cross support frame 21 plays a role in supporting the rotating shaft 22. When the suction fan 2 needs to work, the rotating shaft 22 will rotate in the middle of 212, thereby driving the fan blade 23 to rotate. The rotation of the fan blade 23 will form a certain amount of wind, so that the suction fan 2 can perform the work of heat absorption and ventilation. Through the function of the suction fan 2, this step can discharge the heat absorbed by the copper fins 16 and the hollow copper tube 15 to the outside, thereby assisting the hollow copper tube 15 and the copper fins 16 in heat absorption work, and further strengthening the ventilation and heat dissipation effect inside the injection molding machine electrical box 11. During operation, the limit plate 3 plays a role in supporting the motor 12. When the motor 12 operates, it will generate vibration. At this time, the vibration will be transmitted to the spring column 31 through the limit plate 3. The spring column 31 will perform telescopic work under the influence of the vibration, so as to relieve a certain amount of vibration. Then the remaining vibration force will be transmitted to the shock pad 32, and the shock pad 32 can weaken the vibration force once again. Through the mutual cooperation of the spring column 31 and the shock pad 32, this step can relieve the vibration generated during the operation of the motor 12, help the motor 12 to be more stable during operation, and at the same time, through shock absorption, it can reduce the noise generated during the operation of the motor 12, thereby reducing noise pollution and providing a relatively good working environment for the staff. During operation, when it is necessary to open the injection molding machine electrical box 11, the hinge 41 can be held first and pulled outwards, and then the box door 4 can be expanded outwards by using the rotating characteristics of the hinge 41, so as to open the injection molding machine electrical box 11. Through the opening of the box door 4, this step can facilitate the staff to perform maintenance, repair and maintenance work on the components inside the injection molding machine electrical box 11. During operation, when the fan blade 23 rotates, its surface will contact the brush 51,At this time, the brush 51 can clean the fan blades 23. This step is that when the suction fan 2 is working, the dust, impurities and oil stains inside the injection molding machine electric box 11 will be discharged along with the exhaust air flow. However, a part of the dust will adhere to the surface of the fan blades 23, and in the long-term accumulation, it may cause the situation of affecting the rotation speed of the fan blades 23. At this time, through the cooperation of the strip plate 5 and the brush 51, the accumulation of dust on the surface of the fan blades 23 can be reduced. During operation, when the suction fan 2 is working, the exhaust air flow will first reach the valve plate 6. At this time, the valve plate 6 expands outward under the influence of the air flow pressure, so that the air flow can be smoothly discharged to the outside. This step is that when the suction fan 2 is not working, the valve plate 6 will be in a closed state, so as to reduce the possibility that the dust and impurities in the outside world may float into the injection molding machine electric box 11 through the suction fan 2, resulting in the pollution of the components inside the injection molding machine electric box 11. During operation, the opening of the ventilation hole 7 can make the air inside the injection molding machine electric box 11 flow with the outside of the limit plate 3. This step can further strengthen the heat dissipation effect of the injection molding machine electric box 11 through the function of the ventilation hole 7, so as to reduce the working load of the suction fan 2.,
