They are characterized by light weight, corrosion resistance, good insulation, and ease of processing. They are widely used in numerous fields, including industry, agriculture, and daily life. Heat dissipation injection molding equipment is a molding device that optimizes the heat dissipation system based on traditional injection molding equipment. It is primarily used to address product defects (such as deformation, shrinkage, and stress concentration) caused by uneven heat dissipation during the polymer material molding process, thereby improving production efficiency and product quality.
[0003] During the operation of the existing heat dissipation injection molding device, there is a certain degree of heat dissipation instability, which can easily lead to uneven heat dissipation and product defects. Therefore, a new design was developed to address this situation. Summary of the Invention

[0005] The molding mechanism includes a molding base, one side of the top of the molding base is fixedly connected to the fixed mold, and during the injection molding process, the cooling device is used to dissipate heat inside the fixed mold, thereby accelerating the molding of the mold, increasing the molding speed of the mold, and improving the operating efficiency of the equipment. An injection tube is fixedly connected to one side of the outside of the fixed mold, and a sliding groove is provided on the top of the molding base away from the fixed mold. A sliding block is slidably connected to the inner side of the sliding groove. The sliding block drives the mobile mold to move toward the side of the fixed mold, and the mobile mold is docked with the fixed mold. The material is injected from the injection tube to achieve the effect of injection molding. The top of the sliding block is fixedly connected to the mobile mold, and the outside of the mobile mold is fixedly connected to the push rod on the side away from the fixed mold. Mechanism, after the mold is formed, the sliding block drives the mobile mold away from the fixed mold, and then pushes the material mold through the pushing mechanism, so as to achieve the effect of quickly falling off the mold, thereby improving the operating efficiency of the equipment, and avoiding mold adhesion, and preventing the equipment from affecting the operating efficiency. The outer side of the pushing mechanism is fixedly connected with a friction mechanism. When the input of material is stopped, after the mobile mold is docked with the fixed mold, the friction mechanism is controlled by the motor to rotate, so as to rub the injection pipe, thereby realizing the cleaning operation of the inner wall of the pipe, avoiding excessive precipitation of impurities after the equipment has been operated for a long time, and preventing the subsequent material flow effect from being affected. The side of the friction mechanism away from the fixed mold is fixedly connected with a motor, and the inner side of the fixed mold is fixedly connected to the outer side of the cooling device.

When the movable mold moves away from the fixed mold, the first electric push rod controls the pushing plate to push outward, thereby demolding the material from the mold, thereby separating the mold from the equipment, and avoiding deviations in the mold forming process, which could affect the mold demolding effect and the subsequent operating efficiency of the equipment.
[0007] Preferably, the friction mechanism includes a friction frame, one side of the outside of the friction frame is fixedly connected to a second electric push rod, one side of the outside of the second electric push rod is fixedly connected to the outside of the pushing frame, the side of the friction frame outside away from the second electric push rod is fixedly connected to the outside of the motor, the output end of the motor is fixedly connected to a rotating shaft, when the movable mold is docked and fitted with the fixed mold, the second electric push rod pushes the rotating shaft to move toward one side of the injection tube, and the motor controls the rotating shaft to rotate, so as to achieve the effect of friction scraping the injection pipe, thereby achieving the effect of cleaning the inner wall of the pipe, cleaning the impurities inside the inner wall, and preventing impurities from clogging after long-term operation, thereby affecting the subsequent normal operation of the equipment, one side of the rotating shaft outside the friction frame is rotatably connected, and the outside of the rotating shaft is fixedly connected to a diamond grinding block, which is made of silicone material and a diamond structure, so as to increase the texture of the component surface, further improve the friction performance, and further improve the friction cleaning effect.

[0008] Preferably, the cleaning device includes a cleaning shell, and the inner side of the cleaning shell is fixedly connected to a cleaning frame. In the process of the rotating shaft being extended and retracted by the second electric push rod, the diamond grinding block is frictionally adapted to the friction block inside the cleaning frame, so as to scrape and clean impurities on the surface of the component, peel off impurities on the surface of the component, avoid excessive accumulation of impurities on the surface of the component, and prevent the subsequent friction effect of the component from being affected. The groove on the outside of the cleaning frame is fixedly connected to a friction block, and the friction block is made of rubber material, so that the friction block and the diamond grinding block are frictionally adapted to reduce wear between components, slow down mechanical damage between components, and thus extend the service life of the equipment. The outer side of the cleaning shell is fixedly connected to a discharging device.
[0009] Preferably, the discharge device includes a discharge frame, a cylindrical block fixedly connected to one side of the discharge frame, a cylindrical housing plugged into the outer side of the cylindrical block, a first fan fixedly connected to one side of the outer side of the cylindrical housing, and the discharge housing fixedly connected to the inner side of the discharge frame. The first fan generates wind force to absorb cleaned impurities from the outside of the discharge housing, causing the impurities to move toward the cylindrical housing. The wind force then drives the impurities to be discharged outward through the first fan, thereby absorbing and cleaning impurities, thereby reducing impurities inside the cleaning housing, avoiding excessive accumulation of impurities inside the device, and preventing the device from affecting operating efficiency.
[0010] Preferably, the outer side of the discharge shell is fixedly connected with an external tube. Through the design of multiple external tubes, the feed pipe is increased, the impurity feeding efficiency is increased, the blockage of some pipes is prevented, and the subsequent operation efficiency of the components is avoided. The inner side of the external tube is fixedly connected with a funnel block. The funnel block plays a role in guiding the movement of impurities. The funnel block adopts a structure with one end wide and the other end narrow. According to Bernoulli's principle, the flow effect of objects is improved by reducing the diameter of the pipe, thereby accelerating the flow speed of impurities. The top of the inner wall of the discharge shell is fixedly connected with a scraping mechanism.
[0011] Preferably, the scraping mechanism includes a connecting shaft, a rotating column rotatably connected to the outer side of the connecting shaft, a paddle fixedly connected to the middle of the outer portion of the rotating column, an arc-shaped frame fixedly connected to both sides of the outer portion of the rotating column, and a scraping plate fixedly connected to one side of the outer portion of the arc-shaped frame. The wind impacts the paddle, causing the arc-shaped frame to drive the scraping plate to rub against the inner wall of the pipe, thereby scraping and cleaning the inner wall of the pipe, reducing impurities on the inner wall of the pipe, preventing impurities from being adsorbed on the inner wall of the pipe after long-term operation of the component, and preventing excessive accumulation that affects subsequent impurities and airflow, thereby avoiding affecting the operating efficiency of the equipment.

[0013] Preferably, a filter cover is fixedly connected to the side of the outside of the connecting plate close to the second fan, and the filter cover serves to block the entry of dust in the airflow, reduce the entry of dust, prevent dust from accumulating on the inner wall of the pipe, prevent affecting the heat dissipation efficiency of the components, and avoid affecting the operating efficiency of the equipment. A rotating mechanism is fixedly connected to one side of the inner wall of the filter cover, and a second pipe is fixedly connected to the side of the outside of the cooling pipe away from the first pipe. A third fan is fixedly connected to the side of the outside of the second pipe away from the cooling pipe. After the equipment has been operated for a long time, impurities in the inner wall of the pipe are likely to gradually increase, thereby increasing the heat dissipation pressure of the pipe. Therefore, the inside of the cooling pipe is backblown by the third fan, so as to clean the dust on the inner wall of the pipe through wind vibration, peel off the dust on the inner wall of the pipe, and then blow the floating dust to the outside through the third fan for discharge, so as to achieve the effect of cleaning internal impurities.

Wind force drives the paddle to rotate, causing the rotating bracket to control the rotating grinding block to rub against the inner wall of the filter housing, thereby cleaning dust and preventing impurities from being adsorbed on the holes in the filter housing, thereby preventing the holes from clogging and affecting air intake efficiency. Therefore, by cleaning, impurities on the components are reduced, the probability of hole clogging is reduced, and the normal operation of the equipment is maintained.
[0015] The present invention provides a heat dissipation injection molding device for polymer plastics. It has the following beneficial effects:
[0016] 1. The heat dissipation injection molding device for polymer plastics is designed with a molding mechanism. The sliding block drives the mobile mold to move toward the side of the fixed mold, the mobile mold is docked with the fixed mold, and the material is injected from the injection tube to achieve the effect of injection molding. During the injection molding process, the cooling device is used to dissipate heat inside the fixed mold, thereby accelerating the mold molding, increasing the mold molding speed, and improving the equipment operation efficiency. After the mold is formed, the sliding block drives the mobile mold away from the fixed mold, and then the pushing mechanism pushes the material mold to achieve the effect of quickly falling off the mold, thereby improving the equipment operation efficiency, and avoiding mold adhesion, and preventing the equipment operation efficiency from being affected. When the material input is stopped, after the mobile mold is docked with the fixed mold, the friction mechanism is controlled by the motor to rotate, thereby rubbing the injection pipe, thereby realizing the cleaning operation of the inner wall of the pipe, avoiding excessive precipitation of impurities after the equipment has been operated for a long time, and preventing the subsequent material flow effect from being affected.
[0017] 2. The heat dissipation injection molding device for polymer plastics is designed with a friction mechanism.

The diamond grinding block adopts silicone material and diamond structure to increase the texture of the component surface, further improve the friction performance, and further improve the friction cleaning effect. The silicone material has a certain wear-resistant effect, thereby reducing the rigid collision between components, slowing down the wear between components, and thus extending the service life of the equipment.
[0018] 3. The heat dissipation injection molding device for polymer plastics is designed with a cleaning device. During the extension and retraction of the rotating shaft through the second electric push rod, the diamond grinding block and the friction block inside the cleaning frame are friction-matched, thereby scraping and cleaning impurities on the surface of the component, peeling off impurities on the surface of the component, avoiding excessive accumulation of impurities on the surface of the component, and preventing the subsequent friction effect of the component from being affected. Secondly, the friction block is made of rubber material, which is friction-matched with the diamond grinding block to reduce wear between components and slow down mechanical damage between components, thereby extending the service life of the equipment.
[0019] 4. The heat dissipation injection molding device for polymer plastics is designed with a discharge device. The first fan generates wind force to absorb the cleaned impurities from the outside of the discharge shell, so that the impurities move toward the cylindrical shell, and then the wind drives the impurities to be discharged outward through the first fan, thereby achieving the effect of absorbing and cleaning impurities, thereby reducing the impurities inside the cleaning shell, avoiding excessive accumulation of impurities inside the equipment, and preventing the equipment from affecting the operating efficiency. Through the design of multiple external pipes, the feed pipe is increased, the impurity feeding efficiency is increased, and the blockage of some pipes is prevented, so as to avoid affecting the subsequent operating efficiency of the components. Secondly, the funnel block plays a role in guiding the movement of impurities. The funnel block adopts a structure with one end wide and the other end narrow. According to the Bernoulli principle, the diameter of the pipe is reduced to improve the flow effect of the object, thereby accelerating the flow speed of impurities.
[0020] 5. The heat dissipation injection molding device for polymer plastics is designed with a cooling device. The second fan generates wind force, so that the airflow flows inside the cooling pipe, and then the airflow is discharged outward, so as to achieve the effect of ventilation and heat dissipation, thereby improving the cooling efficiency of the mold, accelerating the operating efficiency of the equipment, shortening the mold molding cycle, preventing thermal fatigue damage to the mold, and avoiding overheating of the internal temperature of the mold, thereby protecting the mold and extending its service life. The filter cover blocks the entry of dust in the airflow, reduces the entry of dust, and prevents dust from accumulating on the inner wall of the pipe, preventing it from affecting the heat dissipation efficiency of the components and the operating efficiency of the equipment. After the equipment has been operated for a long time, the impurities in the inner wall of the pipe are likely to gradually increase, thereby increasing the heat dissipation pressure of the pipe. Therefore, the third fan is used to backflush the inside of the cooling pipe, so as to clean the dust on the inner wall of the pipe through wind vibration, peel off the dust on the inner wall of the pipe, and then blow the floating dust to the outside through the third fan to achieve the effect of cleaning internal impurities.

During the injection molding process, the cooling device 3 is used to dissipate heat inside the fixed mold 15, thereby accelerating the mold molding, increasing the mold molding speed, and improving the equipment operation efficiency. After the mold is formed, the sliding block 13 drives the movable mold 14 away from the fixed mold 15, and then pushes the material mold through the pushing mechanism 17 to achieve the effect of quickly falling off the mold, thereby improving the equipment operation efficiency, and avoiding mold adhesion and affecting the equipment operation efficiency. When the material input is stopped, after the movable mold 14 is docked with the fixed mold 15, the friction mechanism 18 is controlled by the motor 19 to rotate, thereby rubbing the injection pipe, thereby realizing the cleaning operation of the inner wall of the pipe, avoiding excessive precipitation of impurities after the equipment has been operated for a long time, and preventing the subsequent material flow effect from being affected.
[0034] The pushing mechanism 17 includes a pushing frame 171, the outer side of which is fixedly connected to one side of the exterior of the movable mold 14. A first electric push rod 172 is fixedly connected to the outer side of the pushing frame 171. A pushing plate 173 is fixedly connected to the outer side of the first electric push rod 172, which is adjacent to the movable mold 14. The outer side of the pushing plate 173 is slidably connected to the inner side of the movable mold 14. The outer side of the pushing frame 171 is fixedly connected to the outer side of the friction mechanism 18. When the movable mold 14 moves away from the fixed mold 15, the first electric push rod 172 controls the pushing plate 173 to push outward, thereby demolding the material from the mold, thereby separating the mold from the equipment and preventing deviations in the mold forming process, which could affect the mold demolding effect and the subsequent operating efficiency of the equipment.
[0035] The friction mechanism 18 includes a friction frame 181, and one side of the outside of the friction frame 181 is fixedly connected to the second electric push rod 182, and one side of the outside of the second electric push rod 182 is fixedly connected to the outside of the pushing frame 171. The side of the outside of the friction frame 181 away from the second electric push rod 182 is fixedly connected to the outside of the motor 19, and the output end of the motor 19 is fixedly connected to the rotating shaft 183, and the side of the outside of the rotating shaft 183 is rotatably connected to the outside of the friction frame 181. The outside of the rotating shaft 183 is fixedly connected to a diamond grinding block 184, and the side of the outside of the friction frame 181 away from the motor 19 is fixedly connected to the outside of the cleaning device 2. After the movable mold 14 is docked and fitted with the fixed mold 15, the second electric push rod 182 pushes the rotating shaft 183 to move toward the side of the injection tube 16, and the motor 19 controls the rotating shaft 183 to rotate, so as to achieve the effect of friction and scraping the injection pipe, thereby achieving the effect of cleaning the inner wall of the pipe, cleaning the impurities inside the inner wall, and preventing impurities from clogging after long-term operation, thereby affecting the subsequent normal operation of the equipment. The diamond grinding block 184 adopts silicone material and diamond structure to increase the texture of the component surface, further improve the friction performance, and further improve the friction cleaning effect. The silicone material has a certain wear-resistant effect, thereby reducing the rigid collision between components, slowing down the wear between components, and thus extending the service life of the equipment.
[0036] The second embodiment, based on the first embodiment, see Figures 5 to 7 As shown, the cleaning device 2 includes a cleaning shell 21, a cleaning frame 22 is fixedly connected to the inner side of the cleaning shell 21, a friction block 23 is fixedly connected to the groove on the outside of the cleaning frame 22, and a discharge device 24 is fixedly connected to the outer side of the cleaning shell 21. When the rotating shaft 183 is extended and retracted by the second electric push rod 182, the diamond-shaped grinding block 184 is frictionally adapted to the friction block 23 inside the cleaning frame 22, thereby scraping and cleaning impurities on the surface of the component, peeling off impurities on the surface of the component, avoiding excessive accumulation of impurities on the surface of the component, and preventing it from affecting the subsequent friction effect of the component. Secondly, the friction block 23 is made of rubber material, so that the friction block 23 and the diamond-shaped grinding block 184 are frictionally adapted to reduce wear between the components and slow down mechanical damage between the components, thereby extending the service life of the equipment.
[0037] The discharge device 24 includes a discharge frame 241. A cylindrical block 242 is fixedly connected to one side of the discharge frame 241. A cylindrical housing 243 is plugged into the outer side of the cylindrical block 242. A first fan 244 is fixedly connected to one side of the outer side of the cylindrical housing 243. A discharge housing 245 is fixedly connected to the inner side of the discharge frame 241. The first fan 244 generates wind force, which absorbs cleaned impurities from the outside of the discharge housing 245, causing the impurities to move toward the cylindrical housing 243. The wind then drives the impurities through the first fan 244 and discharges them outward. This absorbs and cleans the impurities, thereby reducing impurities inside the cleaning housing 21 and preventing excessive accumulation of impurities inside the device, which could affect the device's operating efficiency.
[0038] An external tube 246 is fixedly connected to the outside of the discharge housing 245, a funnel block 247 is fixedly connected to the inside of the external tube 246, and a scraping mechanism 248 is fixedly connected to the top of the inner wall of the discharge housing 245. The design of multiple external tubes 246 increases the feed pipe, improves the efficiency of impurity feeding, and prevents partial pipe blockage, which affects the subsequent operation efficiency of the component. Secondly, the funnel block 247 plays a role in guiding the movement of impurities. The funnel block 247 adopts a structure with one end wide and the other narrow. According to Bernoulli's principle, by reducing the pipe diameter, the flow effect of objects is improved, thereby accelerating the flow of impurities.
[0039] The scraping mechanism 248 includes a connecting shaft 2481, rotatably connected to a rotating column 2482 on the outside of the connecting shaft 2481. A paddle 2483 is fixedly connected to the middle of the exterior of the rotating column 2482. Curved frames 2484 are fixedly connected to both sides of the exterior of the rotating column 2482. A scraping plate 2485 is fixedly connected to one side of the exterior of the curved frame 2484. Wind impacts the paddle 2483, causing the curved frame 2484 to drive the scraping plate 2485 to rub against the inner wall of the pipe. This scrapes and cleans the inner wall of the pipe, reducing impurities on the inner wall and preventing them from being adsorbed on the inner wall after long-term operation. This prevents excessive accumulation that affects subsequent impurities and airflow, thereby reducing the operating efficiency of the equipment.
[0040] The third embodiment, based on the first and second embodiments, see Figures 8 and 9As shown, the cooling device 3 includes a cooling pipe 31. A first connecting pipe 32 is fixedly connected to one side of the cooling pipe 31. A connecting plate 33 is fixedly connected to the side of the first connecting pipe 32 away from the cooling pipe 31. A second fan 34 is fixedly connected to the side of the connecting plate 33 away from the first connecting pipe 32. The second fan 34 generates wind force, causing air to flow inside the cooling pipe 31, and then the air is discharged outward, thereby achieving ventilation and heat dissipation, thereby improving mold cooling efficiency, accelerating equipment operation efficiency, shortening mold molding cycle, preventing mold thermal fatigue damage, and preventing overheating inside the mold, thereby protecting the mold and extending its service life.
[0041] A filter cover 35 is fixedly connected to the side of the connecting plate 33 proximate to the second fan 34. A rotating mechanism 36 is fixedly connected to the inner wall of the filter cover 35. A second pipe 37 is fixedly connected to the side of the cooling duct 31 proximate to the first pipe 32. A third fan 38 is fixedly connected to the side of the second pipe 37 proximate to the cooling duct 31. The filter cover 35 blocks dust from entering the airflow, reducing dust ingress and preventing dust accumulation on the inner wall of the duct, thereby preventing it from affecting the heat dissipation efficiency of components and the operating efficiency of the equipment. After long-term operation of the equipment, impurities tend to accumulate on the inner wall of the duct, thereby increasing the heat dissipation pressure of the duct. Therefore, the third fan 38 back-blows the interior of the cooling duct 31, thereby clearing dust from the inner wall of the duct through wind vibration, stripping the dust from the inner wall of the duct. The third fan 38 then blows the floating dust outward, thereby clearing the internal impurities.
[0042] Rotating mechanism 36 includes a connecting shaft 361, rotatably connected to a rotating housing 362 on its outer side. A paddle 363 is fixedly connected to one side of the exterior of rotating housing 362. A rotating bracket 364 is fixedly connected to the exterior of rotating housing 362, away from paddle 363. A rotating grinding block 365 is rotatably connected to one side of the exterior of rotating bracket 364. Wind power drives paddle 363 to rotate, causing rotating bracket 364 to control rotating grinding block 365 to rub against the inner wall of filter housing 35, thereby cleaning dust and preventing impurities from adsorbing into the holes of filter housing 35, thereby preventing them from clogging and affecting air intake efficiency. Therefore, cleaning reduces impurities on components, lowering the probability of hole clogging and maintaining normal operation of the equipment.
[0043] During use, the sliding block 13 drives the movable mold 14 to move toward the side of the fixed mold 15, and the movable mold 14 is docked with the fixed mold 15, and the material is injected from the injection tube 16 to achieve the effect of injection molding. During the injection molding process, the cooling device 3 is used to dissipate heat inside the fixed mold 15, thereby accelerating the mold molding, increasing the mold molding speed, and improving the equipment operation efficiency. The cooling device 3 generates wind through the second fan 34 to make the air flow flow inside the cooling pipe 31, and then the air flow is discharged outward to achieve the effect of ventilation and heat dissipation, thereby improving the mold cooling efficiency, accelerating the equipment operation efficiency, shortening the mold molding cycle, preventing the mold from being damaged by thermal fatigue, and avoiding overheating of the internal temperature of the mold, thereby protecting the mold and extending its service life. The filter cover 35 blocks the dust from entering the air flow, reduces the dust from entering, and avoids dust accumulation on the inner wall of the pipe, preventing it from affecting the heat dissipation efficiency of the components and the equipment operation efficiency. After the equipment has been operated for a long time , impurities in the inner wall of the pipe tend to gradually increase, thereby increasing the heat dissipation pressure of the pipe. Therefore, the third fan 38 is used to back-blow the inside of the cooling pipe 31, so as to clean the dust on the inner wall of the pipe through wind vibration, peel off the dust on the inner wall of the pipe, and then use the third fan 38 to blow the floating dust to the outside and discharge it, so as to achieve the effect of cleaning internal impurities. After the mold is formed, the sliding block 13 drives the movable mold 14 away from the fixed mold 15, and then pushes the material mold through the pushing mechanism 17 to achieve the effect of quickly falling off the mold, thereby improving the equipment operation efficiency, and avoiding mold adhesion, and preventing the equipment from affecting the operation efficiency. When the material input is stopped, after the movable mold 14 is docked with the fixed mold 15, the friction mechanism 18 is controlled by the motor 19 to rotate, so as to rub the injection pipe, thereby realizing the cleaning operation of the inner wall of the pipe, avoiding excessive precipitation of impurities after the equipment has been operated for a long time, and preventing the subsequent material flow effect from being affected.
[0044] A cleaning device 2 is provided on the outside of the pushing mechanism 17. When the friction mechanism 18 is frictionally adapted to the cleaning device 2, the cleaning device 2 makes the diamond grinding block 184 frictionally adapted to the friction block 23 inside the cleaning frame 22 during the extension and retraction of the rotating shaft 183 through the second electric push rod 182, so as to scrape and clean impurities on the surface of the component, peel off impurities on the surface of the component, avoid excessive accumulation of impurities on the surface of the component, and prevent affecting the subsequent friction effect of the component. Secondly, the friction block 23 is made of rubber material, so that the friction block 23 is frictionally adapted to the diamond grinding block 184, thereby reducing wear between components, slowing down mechanical damage between components, and thus extending the service life of the equipment.
