Description

Technical Field

[0001] This invention relates to the field of injection molding equipment technology, specifically an injection molding equipment for integrated shoe manufacturing. Background Technology

[0002] In the field of injection molded shoe manufacturing, integrated injection molding equipment is the core equipment for achieving efficient sole molding. The matching structure between its nozzle and mold gate directly determines the stability of molten material delivery, molding quality, and production continuity. After the injection molding operation is completed, some high-temperature molten material remains in the nozzle runner. This part of the molten material is in a semi-molten state, has strong viscosity, and forms a large adhesion force with the inner wall of the nozzle runner, making it difficult to completely remove the residue. The problem of incomplete cleaning of residual molten material in the nozzle not only leads to blockage of the nozzle runner, affecting the normal operation of subsequent injection molding operations and causing production interruptions, but also causes the residual molten material to mix with the new molten material in subsequent injection molding processes. Since the residual molten material may degrade and deteriorate, it will affect the mechanical properties and appearance quality of the sole product, resulting in a decrease in product qualification rate. At the same time, frequent shutdowns to clean residual material will significantly reduce production efficiency, increase labor maintenance costs, and restrict the large-scale and high-quality development of the injection molded shoe manufacturing industry. Therefore, this invention provides an integrated injection molding equipment for injection molded shoes. Summary of the Invention

[0003] The purpose of this invention is to provide an injection molding equipment for one-piece injection molded shoes to solve the problems mentioned in the background art.

[0004] The technical solution of this invention is: an injection molding machine for integrated injection shoes, comprising a base, an electric telescopic rod one fixedly installed on the side wall of the base, a base block one fixedly installed at the telescopic end of the electric telescopic rod one, a base plate fixedly installed on the top of the base block one, an injection nozzle fixedly installed on the top of the base plate, a vertical plate welded to the top of the base plate, an electric telescopic rod two fixedly installed on the side wall of the vertical plate, a base block two fixedly installed at the telescopic end of the electric telescopic rod two, a mounting frame fixedly installed on the top of the base block two, a limit ring welded to the top of the mounting frame, two symmetrical semi-circular push rods slidably arranged in the central through hole of the limit ring, extension rods welded to the back of each of the two semi-circular push rods, and limit rods welded to the side of each of the two extension rods away from the corresponding semi-circular push rod, and an electric telescopic rod fixedly installed on the top inner side of the mounting frame. The third electric telescopic rod has a fixed limiting frame installed at its bottom telescopic end. Two symmetrical limiting grooves are provided on the side walls of the limiting frame, and several limiting rods are slidably positioned within the corresponding limiting grooves. During use, the device actively controls the injection pressure within the nozzle flow channel by synchronously moving two symmetrically arranged semi-circular push rods. After injection, the semi-circular push rods retract, simultaneously pressurizing and guiding gas into the nozzle flow channel. This helps to expel some of the high-temperature molten material and rapidly cools the remaining molten material. The push rods then advance forward to thoroughly scrape away any residual molten material within the nozzle flow channel. For molten material with strong adhesion, the two semi-circular push rods can be staggered to achieve the effect of scraping only one side of the molten material at a time. Through alternating and coordinated scraping, the molten material within the flow channel is thoroughly cleaned and smoothly discharged.

[0005] Preferably, two symmetrical vertical rods are welded to the bottom left and right sides of the inner side of the mounting frame, and two symmetrical vertical holes are opened on the left and right sides of the limiting frame. Several vertical rods are slidably set in the corresponding vertical holes. The vertical rods and vertical holes can limit the limiting frame during the movement process and ensure its stability during the movement process.

[0006] Preferably, each of the semicircular push rods has an air hole inside, and the back of each semicircular push rod is connected to a semicircular air tube that communicates with the corresponding air hole, and the two semicircular air tubes are slidably connected.

[0007] Preferably, a semi-circular piston block is welded to the back of each of the semi-circular trachea, and an air hole 2 is opened on the side of the two semi-circular piston blocks that are close to each other, and an air hole 3 is opened through the two semi-circular piston blocks.

[0008] Preferably, a sleeve is fixedly installed on the top of the base plate, and two semi-circular piston blocks are slidably disposed inside the sleeve. An air inlet pipe is connected to the back of the sleeve, and a one-way air inlet valve is provided on the air inlet pipe. Several pressure cylinders are circumferentially connected at equal intervals on the outer ring surface of the sleeve. A piston plate is slidably disposed inside each pressure cylinder. A pressure spring is connected to the top of each piston plate, and the side of several pressure springs away from the corresponding piston plate is respectively connected to the top of the inner cavity of the corresponding pressure cylinder. An air hole is opened through the top of the pressure cylinder.

[0009] Preferably, a circular plate is welded to the inner wall of each of the air holes, and two symmetrical air holes are opened through the side wall of each circular plate. A sliding rod is slidably arranged on the side wall of each circular plate, and a sealing block is welded to the end of each sliding rod. A mounting plate is welded to the side of each sliding rod away from the corresponding sealing block, and a sealing spring is wound around the body of each sliding rod. Several sealing springs are respectively connected between the corresponding circular plate and the corresponding mounting plate. After injection molding is completed, the electric telescopic rod one drives the nozzle to reset; then the electric telescopic rod two drives the two symmetrically arranged semi-circular push rods to move backward. The semi-circular push rods push the semi-circular air tube and the semi-circular piston block to move backward, so that the semi-circular piston block moves into the inner cavity of the sleeve. This compresses the internal space of the sleeve; as the semi-circular piston block moves backward, the internal air pressure of the sleeve gradually increases and pushes the piston plate upward. When the air hole three on the semi-circular piston block moves into the inside of the sleeve, the pressurized gas enters the air hole one through the air hole three, air hole two and the semi-circular air pipe in sequence. Then the pressurized gas pushes the sealing block out of the air hole one through the air hole five, so that the pressurized gas enters the nozzle flow channel; the high-pressure airflow pushes out some of the high-temperature molten material stuck in the nozzle flow channel, which facilitates the subsequent scraping operation of the semi-circular push rod; at the same time, the high-pressure airflow at room temperature can cool down the high-temperature molten material that has not been discharged, thereby reducing the adhesion between it and the inner wall of the nozzle flow channel. This further promotes the subsequent scraping operation of the semi-circular push rod. Preferably, the top of the nozzle is connected to a feed pipe, and a pressure sensor is installed on the feed pipe.

[0010] This invention provides an improved one-piece injection molding equipment for shoes, which has the following improvements and advantages compared with the prior art: In summary, this device allows for active control of the injection pressure within the nozzle flow channel through the synchronous movement of two symmetrically arranged semi-circular push rods. After injection, the semi-circular push rods retract, simultaneously pressurizing and guiding gas into the nozzle flow channel. This helps expel some of the high-temperature molten material and rapidly cools any remaining molten material. Subsequently, the push rods advance forward to thoroughly scrape away any residual molten material within the nozzle flow channel. For molten material with strong adhesion, the two semi-circular push rods can be staggered to achieve the effect of scraping only one side of the molten material at a time. Through alternating and coordinated scraping, the device ensures that the molten material within the flow channel is thoroughly cleaned and smoothly discharged. Attached Figure Description

[0013] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] This invention provides an improved one-piece injection molding equipment for shoes. The technical solution of this invention is as follows: like Figures 1-9As shown, an injection molding machine for integrated shoe manufacturing includes a base 1. An electric telescopic rod 2 is fixedly installed on the side wall of the base 1. A base block 3 is fixedly installed at the telescopic end of the electric telescopic rod 2. A base plate 4 is fixedly installed on the top of the base block 3. A nozzle 5 is fixedly installed on the top of the base plate 4. A material conveying pipe 37 is connected to the top of the nozzle 5. A pressure sensor 38 is installed on the material conveying pipe 37. A vertical plate 6 is welded to the top of the base plate 4. An electric telescopic rod 7 is fixedly installed on the side wall of the vertical plate 6. A base block 8 is fixedly installed at the telescopic end of the electric telescopic rod 7. A base block 8 is fixedly installed on the top of the base block 8. The mounting bracket 9 has a limit ring 10 welded to its top. Two symmetrical semi-circular push rods 11 are slidably mounted within the central through hole of the limit ring 10. Extension rods 12 are welded to the back of each of the two semi-circular push rods 11. Limit rods 13 are welded to the side of each extension rod 12 away from its corresponding semi-circular push rod 11. An electric telescopic rod 14 is fixedly mounted on the top inner side of the mounting bracket 9. A limit frame 15 is fixedly mounted on the bottom telescopic end of the electric telescopic rod 14. Two symmetrical limit grooves 16 are formed on the side walls at both ends of the limit frame 15, and several limit rods 13 slide along the grooves. The active device is set within the corresponding limiting groove 16. During use, the upper part of the shoe body is placed into the mold 39. Then, the electric telescopic rod 2 moves the bottom block 3, bottom plate 4, and nozzle 5, causing the nozzle 5 to fit tightly against the gate 40 on the side wall of the mold 39. Subsequently, the external material supply structure delivers high-temperature molten material into the nozzle 5 through the material delivery pipe 37. The high-temperature molten material enters the cavity of the mold 39 through the nozzle 5 and gate 40, filling the space enclosed by the bottom of the shoe body and the cavity of the mold 39, thus completing the injection molding of the sole. During this process, if... When the pressure sensor 38 detects that the injection pressure in the cavity is too high, the external controller can control the electric telescopic rod 7 to move the base block 8, mounting bracket 9, limit frame 15 and the two symmetrically arranged semi-circular push rods 11 backward, thereby expanding the internal space of the nozzle 5 and reducing the injection pressure in its cavity; if the pressure sensor 38 detects that the injection pressure in the cavity is too low, the electric telescopic rod 7 will move the two symmetrically arranged semi-circular push rods 11 forward, thereby compressing the internal space of the nozzle 5 and increasing the injection pressure in its cavity.

[0015] Furthermore, each semi-circular push rod 11 has an air hole 19 inside, and each semi-circular push rod 11 has a semi-circular air pipe 20 connected to the back of the corresponding air hole 19. The two semi-circular air pipes 20 are slidably connected. A semi-circular piston block 21 is welded to the back of each semi-circular air pipe 20. An air hole 22 is opened on the side of the two semi-circular piston blocks 21 that is close to each other. An air hole 3 23 is opened through the two semi-circular piston blocks 21. A sleeve 24 is fixedly installed on the top of the base plate 4, and the two semi-circular piston blocks 21 are slidably disposed inside the sleeve 24. A return spring 41 is connected between the two semi-circular piston blocks 21 and the inner wall of the sleeve 24. An air inlet is connected to the back of the sleeve 24. Pipe 25, an intake pipe 25 is equipped with a one-way intake valve 26, and a number of pressure cylinders 27 are circumferentially connected at equal intervals on the outer ring surface of sleeve 24. Each pressure cylinder 27 has a piston plate 28 slidably mounted inside, and a pressure spring 29 is connected to the top of each piston plate 28. The side of each pressure spring 29 away from the corresponding piston plate 28 is connected to the top of the inner cavity of the corresponding pressure cylinder 27. A vent 30 is opened through the top of each pressure cylinder 27. A circular plate 31 is welded to the inner wall of each vent 30. Two symmetrical vents 32 are opened through the side wall of each circular plate 31. A sliding rod 33 is slidably mounted on the side wall of each circular plate 31, and a sealing block 34 is welded to the end of each sliding rod 33. Mounting plates 35 are welded to the side of rod 33 away from the corresponding sealing block 34. Each sliding rod 33 has a sealing spring 36 wound around its body, and several sealing springs 36 are respectively connected between the corresponding circular plate 31 and the corresponding mounting plate 35. After injection molding is completed, the electric telescopic rod 1 2 drives the nozzle 5 to reset. Then, the electric telescopic rod 2 7 drives the two symmetrically arranged semi-circular push rods 11 to move backward. The semi-circular push rods 11 push the semi-circular air pipe 20 and the semi-circular piston block 21 to move backward, so that the semi-circular piston block 21 moves into the inner cavity of the sleeve 24, thereby compressing the internal space of the sleeve 24. As the semi-circular piston block 21 moves backward, the air pressure inside the sleeve 24 gradually increases and pushes the piston. As plate 28 moves upward, when the air hole 3 23 on the semi-circular piston block 21 moves into the sleeve 24, the pressurized gas enters the air hole 19 through the air hole 3 23, the air hole 22, and the semi-circular air pipe 20 in sequence. Then, the pressurized gas pushes the sealing block 34 out of the air hole 19 through the air hole 5 32, allowing the pressurized gas to enter the nozzle 5 flow channel. The high-pressure airflow pushes out some of the high-temperature molten material retained in the nozzle 5 flow channel, which facilitates the subsequent scraping operation of the semi-circular push rod 11. At the same time, the high-pressure airflow at room temperature can cool down the high-temperature molten material that has not been discharged, thereby reducing its adhesion to the inner wall of the nozzle 5 flow channel. This further promotes the subsequent scraping operation of the semi-circular push rod 11.

[0016] Furthermore, two symmetrical vertical rods 17 are welded to the bottom left and right sides of the inner side of the mounting frame 9. Two symmetrical vertical holes 18 are opened on the left and right sides of the limiting frame 15, and several vertical rods 17 are slidably installed in the corresponding vertical holes 18. After the temperature drops, the electric telescopic rod 2 7 drives the semi-circular push rod 11 to move forward. The moving semi-circular push rod 11 scrapes off the molten material that has not been discharged from the flow channel of the nozzle 5, so as to avoid affecting the subsequent injection molding operation. During this process, if the molten material has strong adhesion to the flow channel of the nozzle 5, the external controller controls the electric telescopic rod 3 14 to drive the limiting frame 15 to move down. The limiting rod 13 on the upper side moves forward along the trajectory of the limiting slide groove 16, and then the limiting rod 13 pushes the upper extension rod 12 to... The semi-circular push rod 11 moves forward to achieve misalignment of the two semi-circular push rods 11. Then, the electric telescopic rod 7 moves the semi-circular push rod 11 forward again. At this time, the upper semi-circular push rod 11 pushes the upper molten material in the nozzle 5 flow channel forward, while the lower molten material does not contact the lower semi-circular push rod 11 temporarily and remains largely stationary. This greatly reduces the forward movement pressure of the electric telescopic rod. Then, the electric telescopic rod 14 drives the limiting frame 15 to move up and down in sequence, so that the two semi-circular push rods 11 move forward alternately, thus successfully extruding the molten material in the nozzle 5 flow channel. The vertical rod 17 and the vertical hole 18 can limit the limiting frame 15 during the movement process to ensure its stability.

[0017] Working principle: During use, the upper part of the shoe body is placed into the mold 39. Then, the electric telescopic rod 2 moves the bottom block 3, bottom plate 4, and nozzle 5, causing the nozzle 5 to fit tightly against the gate 40 on the side wall of the mold 39. Subsequently, the external material supply structure delivers high-temperature molten material into the nozzle 5 through the material delivery pipe 37. The high-temperature molten material enters the cavity of the mold 39 through the nozzle 5 and gate 40, filling the space enclosed by the bottom of the shoe body and the cavity of the mold 39, thus completing the injection molding of the sole. During this process, if the set pressure... When sensor 38 detects that the injection pressure inside the cavity is too high, the external controller can control the electric telescopic rod 7 to move the base block 8, mounting bracket 9, limit frame 15 and the two symmetrically arranged semi-circular push rods 11 backward, thereby expanding the internal space of the nozzle 5 and reducing the injection pressure inside its cavity; if the pressure sensor 38 detects that the injection pressure inside the cavity is too low, the electric telescopic rod 7 will move the two symmetrically arranged semi-circular push rods 11 forward, thereby compressing the internal space of the nozzle 5 and increasing the injection pressure inside its cavity. After injection molding is completed, the electric telescopic rod 2 drives the nozzle 5 to reset; then the electric telescopic rod 7 drives the two symmetrically arranged semi-circular push rods 11 to move backward. The semi-circular push rods 11 push the semi-circular air pipe 20 and the semi-circular piston block 21 backward, causing the semi-circular piston block 21 to move into the inner cavity of the sleeve 24, thereby compressing the internal space of the sleeve 24. As the semi-circular piston block 21 continues to move backward, the air pressure inside the sleeve 24 gradually increases and pushes the piston plate 28 upward. When the air hole 23 on the semi-circular piston block 21 moves into the inside of the sleeve 24, the pressurized air... Gas sequentially enters vent 19 through vent 3 23, vent 2 22, and the semi-circular air pipe 20. Subsequently, the pressurized gas pushes the sealing block 34 out of vent 19 through vent 5 32, allowing the pressurized gas to enter the nozzle 5 flow channel. The high-pressure airflow pushes out some of the high-temperature molten material retained in the nozzle 5 flow channel, facilitating the subsequent scraping operation of the semi-circular push rod 11. Simultaneously, the room-temperature high-pressure airflow cools the remaining high-temperature molten material, reducing its adhesion to the inner wall of the nozzle 5 flow channel, further promoting the scraping operation of the subsequent semi-circular push rod 11. After the temperature drops, the electric telescopic rod 7 moves the semi-circular push rod 11 forward. The moving semi-circular push rod 11 scrapes away the molten material that has not been discharged from the nozzle 5 flow channel, preventing it from affecting subsequent injection molding operations. During this process, if the molten material has strong adhesion to the nozzle 5 flow channel, the external controller controls the electric telescopic rod 14 to move the limiting frame 15 downward. The upper limiting rod 13 moves forward along the trajectory of the limiting groove 16, thereby pushing the upper extension rod 12 and the semi-circular push rod 11 forward, thus realizing the movement of the two semi-circular push rods. The misalignment of the push rod 11; then the electric telescopic rod 2 7 again drives the semi-circular push rod 11 forward. At this time, the semi-circular push rod 11 on the upper side pushes the upper molten material in the nozzle 5 flow channel forward, while the molten material on the lower side does not contact the lower semi-circular push rod 11 temporarily and remains largely stationary. This greatly reduces the forward movement pressure of the electric telescopic rod. Then the electric telescopic rod 3 14 drives the limit frame 15 to move up and down reciprocally in sequence, achieving the effect of scraping only the molten material on one side at a time. Through alternating linkage scraping, it is ensured that the molten material in the nozzle 5 flow channel is thoroughly cleaned and smoothly discharged.
