Description

Technical Field

[0001] The present invention relates to the technical field of injection molding, and particularly to an anti-blocking injection molding device for a battery middle cover. Background Art

[0002] The battery middle cover is a key component of the battery assembly, mainly used for sealing and protecting the battery cells and other components inside the battery. In terms of position, it is located at the top of the battery (or in a specific enclosed position according to the battery structure design), playing a role in isolating the inside of the battery from the external environment. In terms of structure, it usually has a specific shape and size to fit different models of battery casings. It is generally made by injection molding or stamping from materials such as plastics and metals. For plastic battery middle covers, engineering plastics with good insulation, mechanical strength, and chemical corrosion resistance, such as ABS and PP, are often selected and can be made into complex shapes through the injection molding process to meet the design requirements of different batteries. Metal battery middle covers have higher strength and good electrical conductivity, and some metal middle covers will also undergo surface treatment to enhance their corrosion resistance and aesthetics. From a functional perspective, its sealing performance is crucial. By closely cooperating with the battery casing and using auxiliary sealing materials such as sealants and sealing rings, it prevents impurities such as moisture and dust from entering the battery interior, avoiding the erosion of the battery cells, and thus ensuring the performance and service life of the battery. At the same time, some specific structures, such as explosion-proof valves, will be provided on the battery middle cover. When the internal pressure of the battery is too high, the explosion-proof valve can automatically open to relieve pressure, preventing dangerous situations such as battery explosion and ensuring the safe use of the battery. In addition, some battery middle covers also integrate structures such as electrode leads for connecting the battery cells inside the battery to the external circuit to achieve the output and input of electrical energy.

[0003] In the daily operation of the existing battery middle cover injection molding device, poor plasticization effect is likely to occur, thus affecting the injection molding effect, and the mold forming efficiency is relatively low. Therefore, a new design is carried out in view of this situation. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: an anti-blocking injection molding device for a battery middle cover, including an injection molding mechanism, the bottom of the injection molding mechanism is fixedly connected with a frame body, a conveying mechanism is fixedly connected to the groove at the top of the frame body, and a mold mechanism is fixedly connected to one side of the frame body near the conveying mechanism; The injection mechanism includes an injection housing. On one side of the injection housing away from the mold mechanism, a first motor is fixedly connected. The inner wall of the injection housing is rotationally connected to a central rotating shaft. On the outer side of the central rotating shaft, blades are fixedly connected. One side of the outer part of the central rotating shaft is fixedly connected to the output end of the first motor. On the outer side of the injection housing, a support base is fixedly connected. On one side of the injection housing away from the frame body, a receiving platform is fixedly connected. On the top of the receiving platform, an input mechanism is fixedly connected. Materials enter from the top of the input mechanism, pass through the conveying mechanism and enter the interior of the injection housing. The input mechanism stirs the injection materials to prevent blockage during the feeding process, avoid mutual friction between particles, prevent the overall fluidity of the materials from deteriorating and blocking the descent of the materials. On one side of the injection housing away from the first motor, a heater is fixedly connected. After the materials enter the interior of the injection housing, the first motor controls the rotation of the central rotating shaft. Under the action of the blades, the rotating blades and the inner wall of the injection housing are used for extrusion and conveying. The materials gradually melt under the action of the heater and then are conveyed to the mold mechanism, thereby achieving the effect of injecting products. Through the cooperation of the input mechanism and the rotating blades, while the materials are evenly fed, time is provided for melting the plastic, and continuous conveying is maintained, thereby keeping the equipment operating normally.

[0005] Preferably, the input mechanism includes an input housing. On the upper side of the inner wall of the input housing, a bearing frame is fixedly connected. On the top of the bearing frame, a second motor is fixedly connected. At the bottom of the bearing frame, a connecting shaft is rotationally connected. The top of the connecting shaft is fixedly connected to the output end of the second motor. At the bottom of the connecting shaft, a screening cover is rotationally connected. Materials enter from the top of the input housing. The screening cover blocks materials with larger particles to avoid uneven materials affecting the melting speed and preventing the injection effect from being affected. The outer side of the screening cover is fixedly connected to the bottom of the inner wall of the input housing. On the outer side of the connecting shaft, a rotating bracket is fixedly connected. The second motor controls the rotation of the connecting shaft to make the rotating bracket stir the materials. Through stirring, the materials are kept evenly dispersed, and at the same time, a certain degree of uniform feeding is maintained to prevent excessive friction between uneven particles, causing the materials to agglomerate inside the equipment, thereby deteriorating the overall fluidity of the materials and blocking the descent of the materials. Secondly, through stirring, the adhesion of the materials is reduced to avoid the situation where the humidity of the materials is too high, the viscosity between particles will increase, and they are easily adhered into lumps, avoiding affecting the feeding effect.

[0006] Preferably, a trapezoidal plate is fixedly connected to the inner side of the rotating bracket. During the rotation of the rotating bracket, the trapezoidal plate is driven to rotate, thereby increasing the stirring range, improving the stirring and turning effect, and enhancing the anti-adhesion effect. A friction mechanism is fixedly connected to the outer side of the rotating bracket away from the connecting shaft. During the rotation of the rotating bracket, the friction mechanism rubs against the inner wall of the input housing, thereby cleaning the materials on the inner wall and reducing the adhesion of materials to the inner wall of the equipment. On the one hand, it avoids the influence of material adhesion on the material flow effect and prevents poor feeding. On the other hand, it avoids the deterioration of materials after adhesion, which is likely to cause corrosion to the equipment and easily affect the service life of the equipment. A rotating mechanism is fixedly connected to the side of the connecting shaft near the bottom. Larger particles of materials settle near the screening cover. The connecting shaft drives the rotating mechanism to rotate, prompting the larger particles to move towards the discharge valve side, facilitating subsequent processing and preventing blockage. A discharge valve is provided on the outer side of the input housing near the screening cover.

[0007] Preferably, the friction mechanism includes a friction housing. A connecting block is fixedly connected to the middle of the inner side of the friction housing. A cylindrical block is rotatably connected between the opposite surfaces of the connecting block. As the friction housing rotates with the rotating bracket, the cylindrical block rubs against the inner wall of the equipment, thereby cleaning the materials on the inner wall and enabling the residual materials to participate in the operation, reducing resource waste. Friction plates are fixedly connected to both sides of the inner side of the friction housing. During the process of cleaning the inner wall of the equipment, the materials may be relatively humid, resulting in adhesion to the surface of the cylindrical block. Therefore, when the cylindrical block rotates, it rubs against the friction plates for adaptation, thereby achieving the effect of cleaning the materials on the surface of the components, playing a certain self-cleaning role, keeping the surface of the object clean, and preventing the influence on the subsequent cleaning effect. Grooves are provided on the outer sides of the friction plates. By providing the grooves, the contact area is increased, improving the cleaning effect. At the same time, it plays a certain heat dissipation effect, avoiding overheating due to friction and preventing the influence on the service life of the components.

[0008] Preferably, the rotating mechanism includes a rotating shaft. The inner side of the rotating shaft is fixedly connected to the outer side of the connecting shaft. A trapezoidal frame is fixedly connected to the outer side of the rotating shaft. The connecting shaft drives the rotating shaft to rotate, causing the trapezoidal frame to stir the materials outside the screening cover, prompting the materials to move towards the discharge valve, facilitating the processing of larger materials, avoiding blockage of the equipment, and maintaining the normal operation of the materials inside the equipment.

[0009] Preferably, the mold mechanism includes a square housing. On one side of the outside of the square housing, an injection mold is fixedly connected. On the side of the injection mold away from the square housing, a connecting column is fixedly connected. On the side of the connecting column away from the injection mold, a receiving body is fixedly connected. On the side of the receiving body close to the connecting column, a hydraulic push block is fixedly connected. Inside the hydraulic push block, a square block is slidably connected. On the side of the square block away from the hydraulic push block, a spring rod is fixedly connected. On the side of the spring rod away from the square block, an ejection mold is fixedly connected. The melted material enters the inside of the injection mold from the injection mechanism. By pushing the ejection mold into the injection mold through the hydraulic push block, the mold extrusion and forming effect is achieved. By retracting the hydraulic push block, the column on the side of the square block close to the receiving body is squeezed, and the spring rod is squeezed towards the ejection mold, thereby achieving the demolding effect, avoiding mold adhesion, and preventing it from affecting subsequent operations. During the process of mold forming, the grooves at the four corners of the ejection mold are slidably connected to the outside of the connecting column. Inside the injection mold, a heat exchange mechanism is fixedly connected. By means of the heat exchange mechanism, heat is exchanged for the mold, increasing the mold cooling speed, thereby promoting mold forming, improving the demolding efficiency, accelerating the operation efficiency. After the mold falls off, it moves towards the conveying mechanism side, and the mold is transported by the conveying mechanism.

[0010] Preferably, the heat exchange mechanism includes a funnel tube. Water flows into the inside of the heat exchange tube from the funnel tube. Through the funnel structure of the funnel tube, according to Bernoulli's principle, by reducing the pipe diameter, the water flow velocity is accelerated, and at the same time, the concentration effect of the water flow is improved, enhancing the heat exchange efficiency. On one side of the outside of the funnel tube, a heat exchange tube is fixedly connected. On the side of the inner wall of the heat exchange tube close to the funnel tube, a spiral plate is fixedly connected. When the water flow passes through the spiral plate, the flow pattern of the water flow is changed through the spiral structure, enhancing the turbulence effect of the water flow, thereby reducing the precipitation of impurities on the inner wall of the equipment, preventing the accumulation of impurities and avoiding affecting the water flow effect. On the inner wall of the heat exchange tube, a rotating mechanism is fixedly connected. By increasing the turbulence effect of the water flow, the impact on the rotating mechanism is increased, causing the rotating mechanism to rotate and scrape the inner wall of the equipment.

[0011] Preferably, the rotating mechanism includes a receiving bracket. Between the opposite surfaces of the receiving bracket, a connecting column is fixedly connected. The outside of the connecting column is rotatably connected to a rotating column. The outside of the rotating column is fixedly connected with a scraping plate. By the impact of the water flow on the scraping plate, the scraping plate is prompted to rotate, thereby achieving scraping of the inner wall of the equipment, reducing the accumulation of impurities on the inner wall of the equipment, keeping the liquid flow smooth, preventing it from affecting the heat exchange effect, keeping the inner wall of the equipment clean, and thus extending the service life of the equipment.

[0012] Preferably, the conveying mechanism includes a conveying housing, a roller shaft is rotatably connected to the inner side of the conveying housing, a conveyor belt is rotatably connected to the outer side of the roller shaft, and a buffer mechanism is fixedly connected to the top of the conveying housing. After the mold is demolded from the mold mechanism, it drops downward, and is shock-absorbed and buffered by the buffer mechanism to reduce the falling impact, avoid excessive impact force, and prevent the mold from being knocked. Then, the roller shaft is rotated by a motor to transport the mold by the conveyor belt, which is convenient for later collection.

[0013] Preferably, the buffer mechanism includes a buffer bracket, and an elastic rod is fixedly connected between the opposite surfaces of the buffer bracket. When the mold drops, it impacts the silica gel plate, and the elastic rod plays a role in shock absorption and buffering to relieve the impact pressure and reduce the vibration amplitude of the components. One side of the outside of the buffer bracket is fixedly connected with a silica gel plate. The silica gel plate is made of silica gel material to enhance the buffer effect of the components, provide a certain protection effect on the mold, avoid damaging the surface of the mold, and avoid affecting the product quality. A plate surface groove is opened on the side of the silica gel plate away from the buffer bracket. By opening the plate surface groove, a certain deformation effect of the component is increased by grooving, and the buffer effect is further enhanced.

[0014] The present invention provides a battery middle cover injection molding device that prevents blockage. It has the following beneficial effects: First, in this battery middle cover injection molding device that prevents blockage, through the design of the injection mechanism, the material enters from the top of the input mechanism, enters the injection housing through the conveying mechanism, and the input mechanism stirs the injection material. By stirring, it prevents the material from being blocked during the feeding process, avoids the mutual friction between particles, which causes the overall fluidity of the material to become poor and blocks the descent of the material. After the material enters the injection housing, the central rotating shaft is rotated by the first motor. Under the action of the blades, the rotating blades and the inner wall of the injection housing are extruded and conveyed, and gradually melts under the action of the heater, and then is conveyed to the mold mechanism, so as to achieve the effect of injecting products. By matching the operation of the input mechanism and the rotating blades, while the material is evenly fed, time is provided for melting the plastic, and continuous conveying is maintained, so as to keep the equipment operating normally.

[0015] II. The anti-blocking injection molding device for the battery middle cover. Through the design of the input mechanism, the material enters from the top of the input housing. The screening cover blocks the materials with larger particles to avoid uneven materials affecting the melting speed and preventing the impact on the injection molding effect. The second motor controls the rotation of the connecting shaft, causing the rotating bracket to stir the materials. By stirring, the materials are kept evenly dispersed, and at the same time, a certain degree of uniform feeding is maintained to prevent excessive friction between uneven particles, which may cause the materials to agglomerate inside the equipment, resulting in a poor overall fluidity of the materials and blocking the descent of the materials. Secondly, stirring reduces the adhesion of the materials to avoid the situation where the humidity of the materials is too high, increasing the viscosity between the particles and easily causing them to stick together in groups, thus avoiding the impact on the feeding effect.

[0016] III. The anti-blocking injection molding device for the battery middle cover. Through the design of the friction mechanism, the friction housing rotates with the rotating bracket, causing the cylindrical block to rub against the inner wall of the equipment to clean the materials on the inner wall, enabling the residual materials to participate in the operation and reducing resource waste. During the process of cleaning the inner wall of the equipment, the materials may have a high humidity and stick to the surface of the cylindrical block. Therefore, when the cylindrical block rotates, it rubs against the friction plate for friction adaptation to clean the materials on the surface of the component, achieving a certain self-cleaning effect, keeping the surface of the object clean, and preventing the impact on the subsequent cleaning effect. Secondly, by opening the plate surface incision and increasing the contact area by opening the groove, the cleaning effect is improved, and at the same time, a certain heat dissipation effect is achieved to avoid overheating due to friction and prevent the impact on the service life of the component.

[0017] IV. The anti-blocking injection molding device for the battery middle cover. Through the design of the mold mechanism, the melted material enters the injection mold from the injection mechanism. The hydraulic push block pushes the ejector mold into the injection mold to achieve the effect of mold extrusion molding. By retracting the hydraulic push block, the column on the side of the square block close to the receiving body is squeezed, causing the spring rod to be squeezed against the ejector mold to achieve the effect of demolding, avoiding mold adhesion and preventing the impact on subsequent operations. During the process of mold forming, the mold is heat exchanged through the heat exchange mechanism to increase the cooling speed of the mold, thereby promoting mold forming, improving the demolding efficiency, and accelerating the operation efficiency. After the mold falls off, it moves towards the conveying mechanism side, and the mold is transported by the conveying mechanism.

[0018] V. In the injection molding device for the anti-blocking battery middle cover, through the design of the heat exchange mechanism, water flows into the interior of the heat exchange pipe from the funnel pipe. Due to the funnel structure of the funnel pipe, according to Bernoulli's principle, by narrowing the pipe diameter, the flow rate of water is accelerated, and at the same time, the concentration effect of water flow is improved, enhancing the heat exchange efficiency. Then the water flow passes through the spiral plate, and the flow pattern of the water flow is changed through the spiral structure, enhancing the turbulent effect of the water flow, thereby reducing the deposition of impurities on the inner wall of the device, preventing the accumulation of impurities and avoiding affecting the water flow effect. By increasing the turbulent effect of the water flow, the impact on the rotating mechanism is increased, causing the rotating mechanism to rotate and scrape the inner wall of the device.

Detailed implementation mode

[0021] 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.

[0022] The first embodiment is as Figures 1 to 5 shown. The present invention provides a technical solution: an anti-blocking injection molding device for the battery middle cover, including an injection mechanism 1. The bottom of the injection mechanism 1 is fixedly connected to a frame 4. A conveying mechanism 3 is fixedly connected to the groove at the top of the frame 4. A die mechanism 2 is fixedly connected to one side of the top of the frame 4 close to the conveying mechanism 3; The injection mechanism 1 includes an injection housing 11. On one side of the injection housing 11 away from the mold mechanism 2, a first motor 12 is fixedly connected. The inner wall of the injection housing 11 is rotatably connected to a central rotating shaft 13. On the outer side of the central rotating shaft 13, a blade 14 is fixedly connected. One side of the outer part of the central rotating shaft 13 is fixedly connected to the output end of the first motor 12. On the outer side of the injection housing 11, a support base 15 is fixedly connected. On one side of the injection housing 11 away from the frame body 4, a receiving platform 16 is fixedly connected. On the top of the receiving platform 16, an input mechanism 17 is fixedly connected. On one side of the injection housing 11 away from the first motor 12, a heater 18 is fixedly connected. The material enters from the top of the input mechanism 17, enters the interior of the injection housing 11 through the input mechanism 17, and the injection material is stirred through the input mechanism 17. By stirring, it is prevented that the material is blocked during the feeding process, and the mutual friction between particles is avoided, so that the overall fluidity of the material becomes poor and the material is blocked from descending. After the material enters the interior of the injection housing 11, the rotation of the central rotating shaft 13 is controlled by the first motor 12. Under the action of the blade 14, the rotating blade 14 and the inner wall of the injection housing 11 are extruded and conveyed, and gradually melted under the action of the heater 18, and then conveyed to the mold mechanism 2, so as to achieve the function of injecting products. Through the operation adaptation of the input mechanism 17 and the rotating blade 14, while the material is evenly fed, time is provided for melting the plastic, and continuous conveying is maintained, so as to keep the equipment operating normally.

[0023] The input mechanism 17 includes an input housing 171. On the upper side of the inner wall of the input housing 171, a bearing frame 173 is fixedly connected. On the top of the bearing frame 173, a second motor 174 is fixedly connected. The bottom of the bearing frame 173 is rotatably connected to a connecting shaft 175. The top of the connecting shaft 175 is fixedly connected to the output end of the second motor 174. The bottom of the connecting shaft 175 is rotatably connected to a screening cover 172. The outer side of the screening cover 172 is fixedly connected to the bottom of the inner wall of the input housing 171. On the outer side of the connecting shaft 175, a rotating bracket 176 is fixedly connected. The material enters from the top of the input housing 171. The screening cover 172 blocks the material with larger particles, avoiding the uneven material from affecting the melting speed and preventing the injection effect from being affected. The rotation of the connecting shaft 175 is controlled by the second motor 174, so that the rotating bracket 176 stirs the material. By stirring, the material is kept evenly dispersed, and at the same time, a certain degree of uniform feeding is maintained, preventing excessive friction between particles due to uneven particles, causing the material to agglomerate inside the equipment, resulting in the overall fluidity of the material becoming poor and blocking the material from descending. Secondly, by stirring, the adhesion of the material is reduced, avoiding the situation that when the humidity of the material is relatively high, the viscosity between particles will increase and it is easy to adhere to each other in groups, avoiding affecting the feeding effect.

[0024] A trapezoidal plate 177 is fixedly connected to the inner side of the rotating bracket 176. A friction mechanism 178 is fixedly connected to the outer side of the rotating bracket 176 away from the connecting shaft 175. A rotating mechanism 179 is fixedly connected to the side of the connecting shaft 175 near the bottom. A discharge valve is arranged on the outer side of the input housing 171 near the screening cover 172. During the rotation of the rotating bracket 176, the trapezoidal plate 177 is driven to rotate, thereby increasing the stirring range, improving the stirring and turning effect, and improving the anti-adhesion effect. During the rotation of the rotating bracket 176, the friction mechanism 178 rubs against the inner wall of the input housing 171, thereby cleaning the materials on the inner wall and reducing the adhesion of materials to the inner wall of the equipment. On the one hand, it avoids the influence of material adhesion on the material flow effect and prevents poor feeding. On the other hand, it avoids the deterioration of materials after adhesion, which is easy to cause corrosion to the equipment and easily affects the service life of the equipment. Larger particles of materials settle near the screening cover 172. The rotating mechanism 179 is driven to rotate by the connecting shaft 175, prompting the larger particles to move towards the discharge valve side, facilitating subsequent processing and preventing blockage.

[0025] The friction mechanism 178 includes a friction housing 1781. A connecting block 1782 is fixedly connected to the middle of the inner side of the friction housing 1781. A cylindrical block 1783 is rotatably connected between the opposite faces of the connecting block 1782. Friction plates 1784 are fixedly connected to both sides of the inner side of the friction housing 1781. Plate surface cuts 1785 are opened on the outer sides of the friction plates 1784. The friction housing 1781 rotates with the rotating bracket 176, causing the cylindrical block 1783 to rub against the inner wall of the equipment, thereby cleaning the materials on the inner wall and enabling the residual materials to participate in the operation, reducing resource waste. During the process of cleaning the inner wall of the equipment, the materials may be relatively humid, resulting in adhesion to the surface of the cylindrical block 1783. Therefore, when the cylindrical block 1783 rotates, it rubs against the friction plates 1784 for adaptation, thereby achieving the effect of cleaning the materials on the surface of the components, playing a certain self-cleaning effect, keeping the surface of the object clean, and preventing the influence on the subsequent cleaning effect. Secondly, by opening the plate surface cuts 1785, the contact area is increased by opening grooves, improving the cleaning effect, and at the same time playing a certain heat dissipation effect, avoiding overheating due to friction and preventing the influence on the service life of the components.

[0026] The rotating mechanism 179 includes a rotating shaft 1791. The inner side of the rotating shaft 1791 is fixedly connected to the outer side of the connecting shaft 175. A trapezoidal frame 1792 is fixedly connected to the outer side of the rotating shaft 1791. The connecting shaft 175 drives the rotating shaft 1791 to rotate, causing the trapezoidal frame 1792 to stir the materials outside the screening cover 172, prompting the materials to move towards the discharge valve, facilitating the processing of larger materials, avoiding blockage of the equipment, and keeping the materials inside the equipment running normally.

[0027] Second embodiment, on the basis of the first embodiment, please refer to Figures 6 to 8As shown in the figure, the mold mechanism 2 includes a square housing 21. On one side outside the square housing 21, an injection mold 22 is fixedly connected. On the side of the injection mold 22 away from the square housing 21, a connecting column 23 is fixedly connected. On the side of the connecting column 23 away from the injection mold 22, a receiving body 24 is fixedly connected. On the side of the receiving body 24 close to the connecting column 23, a hydraulic push block 25 is fixedly connected. Inside the hydraulic push block 25, a square block 26 is slidably connected. On the side of the square block 26 away from the hydraulic push block 25, a spring rod 28 is fixedly connected. On the side of the spring rod 28 away from the square block 26, an ejection mold 27 is fixedly connected. The grooves at the four corners of the ejection mold 27 are slidably connected to the outside of the connecting column 23. Inside the injection mold 22, a heat exchange mechanism 29 is fixedly connected. The melted material enters the inside of the injection mold 22 from the injection mechanism 1. By pushing the ejection mold 27 into the inside of the injection mold 22 through the hydraulic push block 25, the function of mold extrusion molding is achieved. By retracting the hydraulic push block 25, the column on the side of the square block 26 close to the receiving body 24 is squeezed, causing the spring rod 28 to be squeezed towards the ejection mold 27, thereby achieving the function of demolding, avoiding mold adhesion, preventing the influence on subsequent operations. During the process of mold forming, the mold is heat exchanged through the heat exchange mechanism 29 to increase the mold cooling speed, thereby promoting mold forming, improving the demolding efficiency, accelerating the operation efficiency. After the mold falls off, it moves towards the conveying mechanism 3, and the mold is transported through the conveying mechanism 3.

[0028] The heat exchange mechanism 29 includes a funnel tube 291. On one side outside the funnel tube 291, a heat exchange tube 292 is fixedly connected. On the side of the inner wall of the heat exchange tube 292 close to the funnel tube 291, a spiral plate 293 is fixedly connected. Inside the inner wall of the heat exchange tube 292, a rotating mechanism 294 is fixedly connected. Water flows from the funnel tube 291 into the inside of the heat exchange tube 292. Through the funnel structure of the funnel tube 291, according to Bernoulli's principle, by reducing the pipe diameter, the flow rate of water is accelerated, and at the same time, the concentration effect of water is improved, enhancing the heat exchange efficiency. Then the water flows through the spiral plate 293, and the flow pattern of water is changed through the spiral structure, enhancing the turbulent effect of water, thereby reducing the deposition of impurities on the inner wall of the equipment, preventing the accumulation of impurities and avoiding affecting the water flow effect. By increasing the turbulent effect of water, the impact on the rotating mechanism 294 is increased, causing the rotating mechanism 294 to rotate and scrape the inner wall of the equipment.

[0029] The rotating mechanism 294 includes a receiving bracket 2941. Between the opposite faces of the receiving bracket 2941, a connecting column 2942 is fixedly connected. The outside of the connecting column 2942 is rotatably connected to a rotating column 2943. The outside of the rotating column 2943 is fixedly connected with a scraper 2944. By the impact of water on the scraper 2944, the scraper 2944 is promoted to rotate, thereby achieving the scraping of the inner wall of the equipment, reducing the accumulation of impurities on the inner wall of the equipment, keeping the liquid flow smooth, preventing the influence on the heat exchange effect, keeping the inner wall of the equipment clean, and thus prolonging the service life of the equipment.

[0030] Third Embodiment. On the basis of the first and second embodiments, please refer to Figures 9 to 10 As shown, the conveying mechanism 3 includes a conveying housing 31. A roller shaft 32 is rotatably connected to the inner side of the conveying housing 31. A conveyor belt 33 is rotatably connected to the outer side of the roller shaft 32. A buffer mechanism 34 is fixedly connected to the top of the conveying housing 31. After the mold is demolded from the mold mechanism 2, it drops downward. The buffer mechanism 34 is used for shock absorption and buffering to reduce the falling impact, avoid excessive impact force, and prevent the mold from being knocked. Then, the roller shaft 32 is rotated by a motor to make the conveyor belt 33 transport the mold, which is convenient for later collection.

[0031] The buffer mechanism 34 includes a buffer bracket 341. An elastic rod 342 is fixedly connected between the opposite surfaces of the buffer bracket 341. A silica gel plate 343 is fixedly connected to one side outside the buffer bracket 341. A plate surface groove 344 is formed on the side of the silica gel plate 343 away from the buffer bracket 341. When the mold drops, it impacts with the silica gel plate 343, and the elastic rod 342 plays a role in shock absorption and buffering to relieve the impact pressure and reduce the vibration amplitude of the components. Secondly, the silica gel plate 343 is made of silica gel material to enhance the buffer effect of the components, provide a certain protection effect on the mold, avoid damaging the surface of the mold, and avoid affecting the product quality. By opening the plate surface groove 344, the grooving increases a certain deformation effect of the components, further enhancing the buffer effect.

[0032] During use, the material enters from the top of the input mechanism 17 inside the injection molding mechanism 1. After the material enters the input mechanism 17, it enters the injection molding housing 11 through the input mechanism 17, and then the injection molding mechanism 1 injects the material into the mold mechanism 2 to achieve the effect of injection molding. During the process of descending the material, the screening cover 172 blocks larger material particles, and then discharges the particles from the discharge valve for subsequent treatment and utilization, so as to prevent blockage of the equipment, maintain the smoothness of the material feeding, and secondly avoid uneven particles from affecting the heat treatment effect, preventing the impact on the subsequent injection molding effect and the product quality. The second motor 174 is used inside the input mechanism 17 to provide kinetic energy for the input mechanism 17. By stirring the material, it prevents the material from stagnating and accumulating on the inner wall of the equipment due to uneven material particles and mutual friction. At the same time, during the stirring process, it prevents the material from getting wet and sticking to the inner wall of the equipment. The inner wall of the injection molding housing 11 is rubbed by the friction mechanism 178 to clean the material on the inner wall, avoid the material from getting wet and caking, affect the subsequent material feeding effect, and reduce resource waste. After the material is fed, the particles are heated by the heater 18 and then injected into the mold mechanism 2. Through the extrusion of the internal components of the mold mechanism 2, the material is extruded into shape. During the injection molding process, the internal heat exchange mechanism 29 of the mold mechanism 2 cools the mold by heat exchange to improve the mold forming speed and the equipment operation efficiency. After the mold is demolded by the mold mechanism 2, it enters the conveying mechanism 3, and the conveying mechanism 3 conveys the mold to facilitate the collection of the mold and reduce the labor cost. Secondly, a buffer mechanism 34 is provided inside the conveying mechanism 3 to buffer the falling mold, so as to play a certain protective effect and avoid damage to the mold, preventing the impact on subsequent use.
