In order to meet market demand, the production of mobile power supplies requires more efficient, precise and high-quality manufacturing equipment, among which injection molding equipment plays a vital role in the production of mobile power supply shells. Injection molding is a process widely used in the manufacture of plastic products, with the advantages of high production efficiency, high product precision, and the ability to form complex shapes. In the production of mobile power supply shells, the technical level of injection molding equipment directly affects the quality, production efficiency and cost of the shell.

[0003] After extensive searching, the publication number is CN118664837A, which discloses a horizontal injection molding machine with a calibration structure, including a machine body, an injection mechanism is arranged on one side of the top surface of the machine body, and a mold opening and closing mechanism is arranged on the other side of the top surface of the machine body. The device in the prior art can automatically adjust the stroke path of the injection cylinder when in use.

[0004] However, although the existing injection molding equipment can adjust the injection cylinder stroke path, there are two major problems when used in the production of mobile power shells. The first is the raw material link. It cannot guarantee the uniformity of the raw materials entering the injection molding, and the feed amount is unstable, which affects the product quality and dimensional accuracy. The second is cleaning and maintenance. The equipment has no relevant structure, and the material residue is difficult to clean. Long-term accumulation will affect performance. Therefore, a mobile power shell production injection molding equipment is proposed to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide an injection molding device for producing mobile power supply shells, which has the advantages of uniform mixing and stable feeding of raw materials, and convenient cleaning of material residues. It can effectively solve the problems of uneven raw materials and unstable feeding amount affecting product quality and dimensional accuracy in the production of mobile power supply shells in existing equipment, and the problem that material residues are difficult to clean and affect equipment performance.

[0008] When the above technical solution is adopted, the first support frame provides stable support for the mixing bin, and the electric heater is easy to install and can be placed. Because its shape and size are adapted to the bottom of the mixing bin, the two are in close contact, and heat can be quickly and evenly transferred from the electric heater to the raw materials in the mixing bin, ensuring that the raw materials are stably heated to the appropriate injection molding temperature, ensuring the injection molding effect, and avoiding product quality problems caused by uneven heating.

[0009] Preferably, the peristaltic pump is fastened to the preset threaded holes of the base plate by means of mounting screws distributed at the four corners; the feed end of the peristaltic pump is connected to an L-shaped liquid extraction tube via a quick-release joint; a first valve is fixedly installed at one end of the liquid extraction tube close to the mixing assembly; the first valve is used to control the circulation of liquid in the liquid extraction tube; the discharge end of the peristaltic pump is connected to an inclined drain pipe via a flange; the drain pipe extends from one end of the peristaltic pump to a suitable position for discharging waste liquid or materials.

[0011] Preferably, a feed port is formed at the rear end of the upper end face of the mixing bin by stamping, and the stamping process can ensure the shape and dimensional accuracy of the feed port. The feed port is square in shape, and its edge smoothly transitions with the upper end face of the mixing bin. A drain hole is formed by drilling at the lower part of the right side wall of the mixing bin, and a thread is processed in the wall of the drain hole. The mixing bin is sealed and connected to the inlet end of the first valve through the threaded interface of the drain hole, and the external thread of the inlet end of the first valve cooperates with the internal thread of the drain hole, and the two are screwed together and sealed with a sealing ring. A reserved groove is formed at the bottom of the left side wall of the mixing bin by cutting, and the shape of the reserved groove is rectangular, and its edge smoothly transitions with the left side wall of the mixing bin.

[0012] When the above technical solution is adopted, the stamping process ensures the shape and dimensional accuracy of the feed port, and the square design facilitates docking with the feed assembly. The drain hole wall is processed with threads, which are screwed together with the external threads at the inlet end of the first valve, and sealed with a sealing ring, which has good sealing performance and prevents material leakage. The reserved groove is rectangular in shape with smooth transition edges, which is convenient for subsequent connection with other auxiliary equipment or operation, ensuring that the material in the mixing bin does not leak during operation, and facilitating the functional expansion of the equipment.

[0013] Preferably, a sealing gasket is installed on the front side of the front baffle by bonding and fixing. The sealing gasket is designed with nitrile rubber material and is firmly adhered to the front side of the front baffle by adhesive. The sealing gasket forms a compression sealing connection with the front baffle through countersunk screws that penetrate the cylinder body mounting plates of the first cylinder and the second cylinder. The countersunk screws pass through the sealing gasket and the cylinder body mounting plate and are screwed together with the front baffle. The countersunk screws generate a compression force on the sealing gasket so that the sealing gasket fits tightly with the front baffle and the cylinder body mounting plate.

[0014] When the above technical solution is adopted, the sealing gasket made of nitrile rubber is oil-resistant, wear-resistant and aging-resistant, and is firmly adhered to the front of the front baffle through the adhesive. The compression force generated by the countersunk screw makes the sealing gasket fit tightly with the front baffle and the cylinder mounting plate, effectively preventing the material from leaking from the front baffle and the cylinder mounting point, ensuring the stability of the internal environment of the mixing bin, avoiding material contamination of other parts of the equipment, and extending the service life of the equipment.

[0016] When the above technical solution is adopted, the screw hole cooperates with the external thread of the second valve, and the installation is simple, and the installation can be completed by simply rotating. The second valve can conveniently control the flow of materials at the rear end of the mixing bin, and accurately control the material discharge volume after the mixing is completed; it can also be used to adjust the pressure in the bin to meet the pressure requirements of different injection molding processes. It is simple to operate, highly reliable, and can flexibly respond to various production needs.

[0017] Preferably, the extrusion plate and the sieve plate are made of high-strength alloy steel of the same diameter. The high-strength alloy steel has high strength and hardness and can withstand greater pressure and impact. The extrusion plate and the sieve plate have the same diameter. The outer circumferential surfaces of the extrusion plate and the sieve plate are inlaid with polytetrafluoroethylene wear-resistant rings, which can reduce the friction between the extrusion plate and the sieve plate and the inner wall of the mixing bin. The outer wall of the polytetrafluoroethylene wear-resistant ring forms a gap-fitting sliding connection with the inner wall of the mixing bin, thereby ensuring that the extrusion plate and the sieve plate can slide smoothly in the mixing bin and preventing material from leaking from the gap.

[0018] When the above technical solution is adopted, high-strength alloy steel ensures that the extrusion plate and the screen plate are not easily deformed and damaged when subjected to large pressure and impact. The polytetrafluoroethylene wear-resistant ring has an extremely low friction coefficient, which can reduce the friction with the inner wall of the mixing bin, allowing the extrusion plate and the screen plate to slide smoothly in the mixing bin, while preventing the material from leaking from the gap, ensuring the stable operation of the components during the mixing and cleaning process, and extending the service life of the equipment.

[0019] Preferably, the material control assembly includes a slide, which is welded and fixedly mounted on the upper end surface of the mixing bin outside the feed port, and a rectangular baffle plate is horizontally slidably mounted on the inner side of the slide through a linear guide rail, and a ceramic layer is inlaid on the lower end surface of the baffle plate to form a sliding seal with the upper end surface of the mixing bin, and a driving motor is fixedly mounted on the front end of the slide through a motor seat, and a screw is coaxially mounted on the driving motor through an elastic coupling, and the screw is threadedly connected to the front end of the baffle plate through a nut pair, and the screw converts the rotational motion into the linear motion of the baffle plate through the nut pair, thereby realizing the control of the feed amount.

[0020] When the above technical solution is adopted, the linear guide rail makes the baffle plate slide smoothly, and the driving motor converts the rotary motion into the linear motion of the baffle plate through the screw and nut pair, which can accurately control the position of the baffle plate, thereby accurately controlling the feed amount. Automatically control the feed amount, reduce manual intervention, improve production efficiency and accuracy, and the lower end face of the baffle plate is inlaid with a ceramic layer and slidably sealed with the upper end face of the mixing bin to prevent material leakage, effectively ensure the accuracy of the amount of raw materials entering the mixing bin, and improve the stability of product quality.

[0021] Preferably, the feeding assembly includes a feed hopper, which is designed with a funnel-shaped structure as a whole. The upper end of the feed hopper has a larger opening to facilitate the feeding of materials. The main structure of the feed hopper is made of high-strength steel and the surface is treated with anti-corrosion. A connecting groove is installed at the rear end of the bottom of the feed hopper, and the connecting groove and the feed hopper are connected by welding. A second support frame is fixedly installed at the front end of the bottom of the feed hopper, and the bottom of the second support frame is fixedly connected to the front end of the upper end of the mixing bin by bolts.

[0022] When the above technical solution is adopted, the funnel-shaped structure makes the upper opening of the feed hopper larger, which is convenient for material feeding and smooth falling. High-strength steel ensures that the feed hopper is strong and durable, and the surface anti-corrosion treatment can prevent corrosion by materials and extend the service life. The connecting groove is welded and connected to the feed hopper, and the connection is firm. The second support frame makes the feed hopper and the mixing bin firmly connected, providing guarantee for the smooth input of raw materials and the long-term stable operation of the equipment.

[0023] Preferably, the bottom of the connecting groove is installed at the inner rear end of the slide by bolt fixing, and the cross-sectional dimension of the bottom of the connecting groove is smaller than the cross-sectional dimension of the material baffle plate, thereby ensuring that the material baffle plate can effectively control the flow of materials at the bottom of the connecting groove, and the upper end surface of the material baffle plate forms a gap-fitting sliding connection with the bottom of the connecting groove, thereby ensuring that the material baffle plate can slide smoothly at the bottom of the connecting groove and preventing material from leaking from the gap.

[0024] When the above technical solution is adopted, the material baffle plate can effectively cover the bottom of the connecting groove and accurately control the material flow. The gap coordination ensures that the material baffle plate can slide smoothly at the bottom of the connecting groove, and prevents the material from leaking from the gap, further improving the accuracy and stability of the feed quantity control, ensuring that the amount of raw materials entering the mixing bin each time meets the production requirements.

[0025] Compared with the prior art, the present invention has the following beneficial effects: The present invention achieves the effect of uniformly mixing the raw materials by setting a mixing component. The front baffle and the rear baffle are respectively installed at the front and rear ends of the mixing bin, and the first cylinder and the second cylinder are fixed on both sides of the front of the front baffle. The first cylinder is connected to the extrusion plate, and the second cylinder is connected to the sieve plate, and the two slide along the slide rod. When mixing, the second cylinder pushes the sieve plate to move back and forth in the mixing bin, stirs and screens the raw materials, breaks up and screens the agglomerated or uneven raw materials, and fully mixes the raw materials of different components, effectively solving the problem of uneven raw materials in existing equipment and ensuring the quality and dimensional accuracy of the injection molding of the mobile power housing.

[0026] The present invention achieves the effect of stable feeding by setting a material control component. The slide is welded to the outside of the feed port on the upper end face of the mixing bin, and a rectangular baffle plate is installed on the inner side through a linear guide rail. The driving motor at the front end of the slide drives the screw through an elastic coupling, and the screw is threadedly connected to the front end of the baffle plate through a nut pair. When the driving motor is running, the rotational motion is converted into the linear motion of the baffle plate through the screw and the nut pair, and the position of the baffle plate at the feed port is accurately controlled, thereby accurately controlling the amount of raw materials entering the mixing bin, avoiding the feed amount from being too much or too little, and effectively solving the problem of unstable feed amount in existing equipment affecting product quality and dimensional accuracy.

[0027] The present invention achieves the effect of conveniently cleaning material residues by setting a connecting structure between a mixing component and a peristaltic pump. A drainage hole is provided at the lower part of the right side wall of the mixing bin, which is sealed and connected to the L-shaped liquid extraction tube at the feed end of the peristaltic pump through a first valve. After the injection molding is completed, the first valve is closed, and cleaning liquid is injected into the mixing bin through the feed component. The second cylinder is started to make the sieve plate flip the cleaning liquid to clean the inside of the mixing bin. After the cleaning is completed, the first valve is opened, and the peristaltic pump is started to discharge the waste liquid and residual materials after cleaning through the drainage pipe, which solves the problem that the material residues of the existing equipment are difficult to clean and affect the equipment performance, prolongs the service life of the equipment, and ensures the stable operation of the equipment.

[0032] Specifically, by setting the mixing component 2, the effect of uniformly mixing the raw materials is achieved. The front baffle 21 and the rear baffle 22 are respectively installed at the front and rear ends of the mixing bin 25. The first cylinder 23 and the second cylinder 24 are fixed on both sides of the front of the front baffle 21. The first cylinder 23 is connected to the extrusion plate 231, and the second cylinder 24 is connected to the sieve plate 241, and the two slide along the slide rod 212. When mixing, the second cylinder 24 pushes the sieve plate 241 to move back and forth in the mixing bin 25, stirs and screens the raw materials, breaks up and screens the agglomerated or uneven raw materials, and fully mixes the raw materials of different components, effectively solving the problem of uneven raw materials in existing equipment and ensuring the quality and dimensional accuracy of the injection molding of the mobile power housing.

[0033] By setting the material control component 4, the effect of stable feeding is achieved. The slide 41 is welded to the outside of the feed port 251 on the upper end of the mixing bin 25, and a rectangular baffle plate 42 is installed on the inside through a linear guide rail. The drive motor 43 at the front end of the slide 41 drives the screw 431 through an elastic coupling, and the screw 431 is threadedly connected to the front end of the baffle plate 42 through a nut pair. When the drive motor 43 is running, the rotational motion is converted into the linear motion of the baffle plate 42 through the screw 431 and the nut pair, and the position of the baffle plate 42 at the feed port 251 is accurately controlled, thereby accurately controlling the amount of raw materials entering the mixing bin 25, avoiding the feed amount from being too much or too little, and effectively solving the problem of unstable feed amount of existing equipment affecting product quality and dimensional accuracy.

[0034] By setting the connecting structure between the mixing component 2 and the peristaltic pump 13, the effect of convenient cleaning of material residues is achieved. A drainage hole 252 is provided at the lower part of the right side wall of the mixing bin 25, which is sealed and connected to the L-shaped liquid suction pipe 132 at the feeding end of the peristaltic pump 13 through the first valve 133. After the injection molding is completed, the first valve 133 is closed, and the cleaning liquid is injected into the mixing bin 25 through the feeding component 3, and the second cylinder 24 is started to make the sieve plate 241 turn over the cleaning liquid to clean the inside of the mixing bin 25. After the cleaning is completed, the first valve 133 is opened, and the peristaltic pump 13 is started to discharge the waste liquid and residual materials after cleaning through the drainage pipe 131, which solves the problem that the material residues of the existing equipment are difficult to clean and affect the equipment performance, prolongs the service life of the equipment, and ensures the stable operation of the equipment.

[0035] Embodiment 2 In order to facilitate effective cleaning of the inside of the equipment after processing, Figure 2 As shown, in this embodiment, a first support frame 111 is fixedly installed on the rear end of the upper end surface of the bottom plate 11, and the top of the first support frame 111 is fixedly connected to the bottom of the mixing bin 25. An electric heater 12 is placed on the upper end surface of the bottom plate 11 inside the first support frame 111. The heating end of the upper end surface of the electric heater 12 is in contact with the bottom of the mixing bin 25 but not fixedly connected. The shape and size of the electric heater 12 are adapted to the bottom of the mixing bin 25, and the electric heater 12 and the mixing bin 25 achieve heat transfer through contact.

[0036] Specifically, the first support frame 111 provides stable support for the mixing bin 25, and the electric heater 12 is easy to install and can be placed. Because its shape and size are adapted to the bottom of the mixing bin 25, the two are in close contact, and heat can be quickly and evenly transferred from the electric heater 12 to the raw materials in the mixing bin 25, ensuring that the raw materials are stably heated to a suitable injection molding temperature, ensuring the injection molding effect, and avoiding product quality problems caused by uneven heating.

[0037] Furthermore, the peristaltic pump 13 is fastened to the preset threaded holes of the base plate 11 by means of mounting screws distributed at the four corners. The feed end of the peristaltic pump 13 is connected to an L-shaped liquid extraction tube 132 via a quick-release joint. A first valve 133 is fixedly installed at one end of the liquid extraction tube 132 close to the mixing component 2. The first valve 133 is used to control the circulation of liquid in the liquid extraction tube 132. The discharge end of the peristaltic pump 13 is connected to an inclined drain pipe 131 via a flange. The drain pipe 131 extends from one end of the peristaltic pump 13 to a suitable position for discharging waste liquid or materials.

[0038] Specifically, the mounting screws distributed at the four corners enable the peristaltic pump 13 to be firmly installed on the base plate 11 to prevent shaking during operation from affecting material transportation. The quick-release connector facilitates the disassembly and installation of the L-shaped liquid extraction tube 132, and is easy to operate when the pipe needs to be replaced or cleaned. The flange-connected sewage pipe 131 is firmly connected, has good sealing, and is convenient to adjust the discharge direction of the sewage pipe 131, which is convenient for controlling material circulation and discharge, effectively improving material transportation efficiency, and making equipment maintenance more convenient.

[0039] Embodiment 3 In order to fully mix the raw materials during the mixing stage, Figures 3 to 5 As shown, in the present embodiment, a feed port 251 is formed at the rear end of the upper end surface of the mixing bin 25 by stamping, and the stamping process can ensure the shape and dimensional accuracy of the feed port 251. The shape of the feed port 251 is square, and its edge smoothly transitions with the upper end surface of the mixing bin 25. A drain hole 252 is formed by drilling at the lower part of the right side wall of the mixing bin 25, and a thread is processed in the wall of the drain hole 252. The mixing bin 25 is sealed and connected to the inlet end of the first valve 133 through the threaded interface of the drain hole 252. The external thread at the inlet end of the first valve 133 cooperates with the internal thread of the drain hole 252, and the two are screwed together and sealed with a sealing ring. A reserved groove 253 is formed at the bottom of the left side wall of the mixing bin 25 by cutting. The shape of the reserved groove 253 is rectangular, and its edge smoothly transitions with the left side wall of the mixing bin 25.

[0040] Specifically, the stamping process ensures the shape and dimensional accuracy of the feed port 251, and the square design facilitates docking with the feed assembly 3. The drain hole 252 wall is threaded and screwed with the external thread of the inlet end of the first valve 133, and is sealed with a sealing ring, which has good sealing performance and prevents material leakage. The reserved groove 253 is rectangular in shape with a smooth transition on the edge, which is convenient for subsequent connection with other auxiliary equipment or operation, ensuring that the material in the mixing bin 25 does not leak during operation, and facilitating the functional expansion of the equipment.

[0041] Furthermore, a sealing gasket 211 is fixedly installed on the front side of the front baffle 21 by bonding. The sealing gasket 211 is designed with nitrile rubber material and is firmly adhered to the front side of the front baffle 21 by adhesive. The sealing gasket 211 is connected to the front baffle 21 by a compressive sealing connection through a countersunk screw that passes through the cylinder mounting plates of the first cylinder 23 and the second cylinder 24. The countersunk screw passes through the sealing gasket 211 and the cylinder mounting plate and is screwed with the front baffle 21. The countersunk screw generates a compressive force on the sealing gasket 211 so that the sealing gasket 211 fits tightly against the front baffle 21 and the cylinder mounting plate.

[0042] Specifically, the sealing gasket 211 made of nitrile rubber is oil-resistant, wear-resistant, and aging-resistant, and is firmly adhered to the front side of the front baffle 21 by an adhesive. The compression force generated by the countersunk screw makes the sealing gasket 211 fit tightly with the front baffle 21 and the cylinder mounting plate, effectively preventing material from leaking from the front baffle 21 and the cylinder mounting point, ensuring the stability of the internal environment of the mixing bin 25, avoiding material contamination of other parts of the equipment, and extending the service life of the equipment.

[0043] Furthermore, the back side of the rear baffle 22 is raised in the middle and has a screw hole, the internal thread of the screw hole matches the external thread of the second valve 221, and the second valve 221 is threadedly installed on the back side of the rear baffle 22 through the screw hole. The second valve 221 is installed in the screw hole of the rear baffle 22 by screwing, thereby achieving a fixed connection with the rear baffle 22, thereby achieving a fixed connection with the rear baffle 22. The second valve 221 can be used to control the material flow or pressure regulation at the rear end of the mixing bin 25.

[0044] Specifically, the screw hole cooperates with the external thread of the second valve 221, and the installation is simple, and the installation can be completed by simply rotating. The second valve 221 can conveniently control the flow of materials at the rear end of the mixing bin 25, and accurately control the discharge amount of materials after the mixing is completed; it can also be used to adjust the pressure in the bin to meet the pressure requirements of different injection molding processes. It is simple to operate, highly reliable, and can flexibly respond to various production needs.

[0045] Furthermore, the extrusion plate 231 and the sieve plate 241 are made of high-strength alloy steel of the same diameter. The high-strength alloy steel has high strength and hardness and can withstand greater pressure and impact. The extrusion plate 231 and the sieve plate 241 have the same diameter size. The outer circumferential surfaces of the extrusion plate 231 and the sieve plate 241 are inlaid with polytetrafluoroethylene wear-resistant rings, which can reduce the friction between the extrusion plate 231 and the sieve plate 241 and the inner wall of the mixing bin 25. The outer wall of the polytetrafluoroethylene wear-resistant ring forms a gap-fitting sliding connection with the inner wall of the mixing bin 25, thereby ensuring that the extrusion plate 231 and the sieve plate 241 can slide smoothly in the mixing bin 25 and preventing material from leaking from the gap.

[0046] Specifically, high-strength alloy steel ensures that the extrusion plate 231 and the screen plate 241 are not easily deformed or damaged when subjected to large pressure and impact. The polytetrafluoroethylene wear-resistant ring has an extremely low friction coefficient, which can reduce the friction with the inner wall of the mixing bin 25, allowing the extrusion plate 231 and the screen plate 241 to slide smoothly in the mixing bin 25, while preventing the material from leaking from the gap, ensuring that the components operate stably during the mixing and cleaning process, and extending the service life of the equipment.

[0047] Embodiment 4 In order to conveniently control the amount of raw materials added, such as Figure 1 , Figure 6 and Figure 7 As shown, in the present embodiment, further, the material control assembly 4 includes a slide 41, which is welded and fixedly mounted on the upper end surface of the mixing bin 25 outside the feed port 251, and a rectangular baffle plate 42 is horizontally slidably mounted on the inner side of the slide 41 through a linear guide rail, and a ceramic layer is inlaid on the lower end surface of the baffle plate 42 to form a sliding seal with the upper end surface of the mixing bin 25, and a driving motor 43 is fixedly mounted on the front end of the slide 41 through a motor seat, and a screw 431 is coaxially mounted on the driving motor 43 through an elastic coupling, and the screw 431 is threadedly connected to the front end of the baffle plate 42 through a nut pair, and the screw 431 converts the rotational motion into the linear motion of the baffle plate 42 through the nut pair, thereby realizing the control of the feed amount.

[0048] Specifically, the linear guide rail allows the baffle plate 42 to slide smoothly, and the driving motor 43 converts the rotational motion into the linear motion of the baffle plate 42 through the screw 431 and the nut pair, which can accurately control the position of the baffle plate 42, thereby accurately controlling the feed amount. Automatically controlling the feed amount reduces manual intervention, improves production efficiency and accuracy, and the lower end surface of the baffle plate 42 is inlaid with a ceramic layer and slidably sealed with the upper end surface of the mixing bin 25 to prevent material leakage, effectively ensuring the accuracy of the amount of raw materials entering the mixing bin 25, and improving the stability of product quality.

[0049] Furthermore, the feed assembly 3 includes a feed hopper 31. The feed hopper 31 is designed with a funnel-shaped structure as a whole. The upper end of the feed hopper 31 has a larger opening to facilitate the feeding of materials. The main structure of the feed hopper 31 is made of high-strength steel and the surface is treated with anti-corrosion. A connecting groove 32 is installed at the rear end of the bottom of the feed hopper 31. The connecting groove 32 and the feed hopper 31 are connected by welding. A second support frame 311 is fixedly installed at the front end of the bottom of the feed hopper 31. The bottom of the second support frame 311 is fixedly connected to the front end of the upper end of the mixing bin 25 by bolts.

[0050] Specifically, the funnel-shaped structure makes the upper opening of the feed hopper 31 larger, which is convenient for material delivery and smooth falling. High-strength steel ensures that the feed hopper 31 is sturdy and durable, and the surface anti-corrosion treatment can prevent corrosion by materials and extend the service life. The connecting groove 32 is welded and connected to the feed hopper 31, and the connection is firm. The second support frame 311 connects the feed hopper 31 to the mixing bin 25 firmly, providing guarantee for the smooth input of raw materials and the long-term stable operation of the equipment.

[0051] Furthermore, the bottom of the connecting groove 32 is installed at the inner rear end of the slide 41 by bolt fixing. The cross-sectional dimension of the bottom of the connecting groove 32 is smaller than the cross-sectional dimension of the material baffle plate 42, thereby ensuring that the material baffle plate 42 can effectively control the flow of materials at the bottom of the connecting groove 32. The upper end surface of the material baffle plate 42 forms a clearance fitting sliding connection with the bottom of the connecting groove 32, thereby ensuring that the material baffle plate 42 can slide smoothly at the bottom of the connecting groove 32 and preventing material from leaking from the gap.

[0052] Specifically, the baffle plate 42 can effectively cover the bottom of the connecting groove 32 and accurately control the flow of materials. The gap fit ensures that the baffle plate 42 can slide smoothly at the bottom of the connecting groove 32, and prevents the material from leaking from the gap, further improving the accuracy and stability of the feed quantity control, ensuring that the amount of raw materials entering the mixing bin 25 each time meets the production requirements.

[0053] When the present invention is used: Preparation: Put the raw materials to be injected into the feed hopper 31, check whether the connections of each component are stable, whether the power is normally connected, and whether the valves, cylinders, motors, etc. are in the initial state. According to the amount of injection molded products required, adjust the position of the rectangular baffle plate 42 by driving the motor 43 to control the feed amount.

[0054] Mixing process: The raw materials pass through the connecting groove 32 and enter the mixing bin 25 under the control of the baffle plate 42. The second cylinder 24 is started to push the screen plate 241 to slide back and forth on the slide bar 212 to stir and screen the raw materials in the mixing bin 25 so that the raw materials are evenly mixed. At the same time, the electric heater 12 is turned on to heat the raw materials in the mixing bin 25 to reach a suitable injection molding temperature.

[0055] Post-mixing treatment and discharge: After the mixing is completed, the first cylinder 23 is started to push the extrusion plate 231 to push the mixed and heated raw materials in the mixing bin 25 to the rear. The second valve 221 is opened. If more precise extrusion of raw materials is required, the extrusion head can be connected to discharge the raw materials into subsequent injection molds and other equipment for injection molding.

[0056] Cleaning and maintenance: After the injection molding is completed, the first valve 133 and the second valve 221 are closed, and the cleaning liquid is injected into the mixing bin 25 through the feed assembly 3. The second cylinder 24 is started, and the cleaning liquid is turned over by sliding the sieve plate 241 on the slide bar 212, so as to clean the inside of the mixing bin 25. After the cleaning is completed, the first valve 133 is opened, the peristaltic pump 13 is started, and the waste liquid after cleaning is discharged through the sewage pipe 131.
