Description

Technical Field

[0001] This invention belongs to the field of injection molding technology, and relates to a shoe sole injection molding device, specifically a device for integrated injection molding of travel shoe soles. Background Technology

[0002] Integrated injection molding of shoe soles, also known as injection molding or injection molding, is a modern process for manufacturing shoe soles. It involves directly injecting liquid or molten raw materials into a mold in which the shoe upper (shoe collar) has already been placed, allowing it to bond with the shoe upper within the mold, and then cooling and solidifying to ultimately form a complete shoe with a firm bond between the sole and the upper.

[0003] Currently, in the injection molding process of shoe soles, various raw materials of different densities or particle sizes (such as base resin, color masterbatch, foaming agent, wear-resistant agent and other functional additives) need to be pre-mixed in the barrel and fall to the screw melting section of the injection molding machine by gravity. However, the existing injection molding machine barrel usually only serves as a passive raw material storage and transition container, resulting in uneven mixing of raw materials and component stratification. The existing barrel lacks an effective active mixing mechanism, and raw materials of different densities and particle sizes are prone to separation during gravity fall. Components with high density or small particles (such as color masterbatch) will sink to the bottom more quickly, while components with low density or large particles will remain on the upper layer. This stratification effect leads to inconsistent raw material ratios entering the screw, which in turn causes quality problems such as color difference and performance fluctuations (such as local hardness or density unevenness) in the final injection-molded shoe sole, seriously affecting the consistency and pass rate of the product.

[0004] In addition, when raw materials enter the high-temperature screw barrel directly at room temperature, a huge temperature gradient is formed. On the one hand, the screw needs to consume more energy to heat these cold materials, increasing the energy consumption of the whole machine. On the other hand, the cold materials are easily subjected to high temperature heating in an instant, which may affect the performance of some additives. It will also cause temperature fluctuations in the plasticizing section of the screw, affecting the stability of the melt quality, thus producing defects such as flow marks, shrinkage or material shortage in the shoe sole. Summary of the Invention

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an integrated injection molding processing device for the soles of travel shoes, which has the advantages of effectively and uniformly distributing, forcibly mixing, and evenly preheating the raw materials in the barrel, thereby improving the quality of injection molding production.

[0006] (II) Technical Solution The above-mentioned technical objective of the present invention is achieved through the following technical solution: an integrated injection molding processing device for the sole of a travel shoe, comprising a rotating frame, wherein a plurality of injection molds are annularly bolted to the top of the rotating frame, an injection molding machine is provided on the front side of the rotating frame, the injection molding machine is used in conjunction with the injection molds, and a material cylinder is fixedly connected to the top of the injection molding machine, wherein a deep mixing structure is provided inside the material cylinder; The deep mixing structure includes an upper material equalization mechanism, which is bolted to the top of the inside of the cylinder. A connecting shaft runs through the inside of the upper material equalization mechanism, and a reciprocating mixing mechanism is bolted to the bottom of the connecting shaft. The bottom of the reciprocating mixing mechanism is rotatably connected to the inner wall of the cylinder. Connecting sleeves are fixedly fitted on the top and bottom of the surface of the reciprocating mixing mechanism, and support rings are fitted on the surface of the connecting sleeves. The support rings are coaxially arranged with the connecting sleeves. Several support rods are bolted in a ring between the opposite sides of the two support rings, and two inclined blades are bolted to the outer side of the support rods.

[0007] The above technical solution employs a double-layer diversion structure in the upper material distribution mechanism. First, the upper diversion divides the raw material into multiple uniform streams, which are then further refined by the lower diversion. This prevents raw material accumulation and ensures that the material is evenly distributed to the lower part of the cylinder, laying the foundation for subsequent deep mixing. Furthermore, the upper material distribution mechanism also has a vibration function, causing the diversion structure to generate continuous micro-vibrations. This prevents raw material from adhering and stagnating in the guide trough and diversion holes, and efficiently breaks up raw material agglomerates, preventing agglomerated raw material from directly entering the mixing stage and causing insufficient mixing. The reciprocating mixing mechanism utilizes axial pushing and longitudinal tumbling of the material through oppositely rotating helical blades, as well as tilted blades rotating around the center of the cylinder. The radial circulation and circumferential shear generated during rotation create a strong three-dimensional convection, diffusion, and shear flow field within the barrel through this combined motion. This enables powerful homogenization of raw material components with different densities and particle sizes, ensuring that masterbatches, additives, and other materials are fully and uniformly dispersed at the microscopic level. Furthermore, the mixing and preheating functions are integrated into one unit. Through the hollow shaft and hot air nozzles, low-temperature hot air is directly and uniformly introduced into the continuously agitated raw material particles, achieving preheating during mixing and mixing during preheating. This results in efficient heat exchange, ensuring that the temperature of the raw materials is uniformly increased before entering the screw, effectively reducing the temperature gradient and avoiding thermal shock.

[0008] The present invention is further configured such that: the reciprocating mixing mechanism includes a first rotating shaft and a second rotating shaft arranged in parallel, a protective shell is fitted between the top of the first rotating shaft and the second rotating shaft, and the first rotating shaft penetrates the interior of the protective shell, transmission gears are fixedly fitted on the surfaces of the first rotating shaft and the second rotating shaft, the two transmission gears mesh with each other, and spiral blades are welded on the surfaces of the first rotating shaft and the second rotating shaft, and the blades of the two spiral blades rotate in opposite directions and are staggered with each other.

[0009] By adopting the above technical solution, a reciprocating mixing mechanism is set up. When the servo motor drives the first rotating shaft to rotate through the connecting shaft, the second rotating shaft is driven to rotate synchronously in the opposite direction through two meshing transmission gears. The reverse spiral blades on the surfaces of the first and second rotating shafts rotate accordingly. The upper layer of raw materials is pushed downward by the spiral blades, and the lower layer of raw materials is lifted upward by the reverse spiral blades, forming an upper and lower convection circulation. The blades are staggered and continuously shear and stir the raw materials during the rotation process, breaking the density stratification and agglomeration of the raw materials, and realizing the uniform mixing of each component. The setting of the reverse spiral blades constructs an upper and lower circulation channel for the raw materials, effectively solving the defect of insufficient mixing between the upper and lower layers in traditional single-shaft mixing, and ensuring the uniform fusion of light and heavy raw materials and different components.

[0010] The present invention is further configured such that: the bottom of the first rotating shaft is rotatably connected to a bracket via a bearing seat, and the outer side of the bracket is bolted to the inner wall of the material cylinder; the top of the material cylinder is bolted to a mounting bracket; the top of the mounting bracket is bolted to a servo motor; and the output end of the servo motor passes through the mounting bracket and is bolted to a connecting shaft.

[0011] The above technical solution provides stable support for the rotating shaft through the combination of bearing housing and bracket, preventing the rotating shaft from shaking or deviating during rotation; the servo motor is connected to the first rotating shaft through the connecting shaft, and the speed can be precisely adjusted according to the characteristics of raw materials and mixing requirements, making it more adaptable.

[0012] The present invention is further configured such that: a bushing is fixedly sleeved at the bottom of the first rotating shaft surface, and a plurality of disturbance rods are annularly welded on the surface of the bushing, and the outer side of the disturbance rods is in rotatable contact with the inner wall of the material cylinder.

[0013] By adopting the above technical solution, the bushing and the disturbance rod rotate synchronously with the first rotating shaft, which can specifically clean the dead corner area at the bottom of the barrel, avoid the deposition of heavy raw materials, ensure that all raw materials in the barrel can participate in the mixing, and further improve the mixing uniformity.

[0014] The present invention is further configured such that: the interior of the first rotating shaft and the second rotating shaft are both hollow, and the surfaces of the first rotating shaft and the second rotating shaft are both annularly connected with a plurality of hot air nozzles; the surfaces of the first rotating shaft and the second rotating shaft are rotatably fitted with movable sleeves, and the movable sleeves are respectively connected to the first rotating shaft and the second rotating shaft; a connecting pipe is fixedly connected between the opposite sides of the two movable sleeves.

[0015] Using the above technical solution, the hot air in the first rotating shaft enters the rear rotating shaft through the front movable sleeve and connecting pipe and finally enters the second rotating shaft. It is then sprayed out from the hot air nozzles that are evenly distributed on the surface of the shaft, so that the hot air is directly injected into the raw material flow that is violently tumbled by the spiral blades and paddle blades. This achieves dynamic and direct contact preheating. The hot air is in full contact with the raw material particles that have a huge surface area and are constantly being renewed, resulting in extremely high heat exchange efficiency. This allows the preheating process to be carried out simultaneously with the mixing process, and the raw material temperature rises evenly. This effectively avoids local overheating or insufficient preheating, thereby reducing the heating load and energy consumption of the screw.

[0016] The present invention is further configured such that: the upper material distribution mechanism includes an upper conical distribution plate and a lower horizontal distribution plate, the upper conical distribution plate and the lower horizontal distribution plate are bolted together, the surface of the upper conical distribution plate is provided with a plurality of guide grooves in an annular shape, the interior of the lower horizontal distribution plate is provided with a plurality of distribution holes in an annular shape, an annular guide plate is bolted to the top edge of the lower horizontal distribution plate, and the other end of the annular guide plate contacts the inner wall of the material cylinder, a connecting ring is welded to the bottom edge of the lower horizontal distribution plate, and a plurality of elastic connecting frames are annularly bolted between the connecting ring and the inner wall of the material cylinder.

[0017] By adopting the above technical solution, and by setting up an upper material distribution mechanism, after the raw material enters the barrel, it first contacts the upper conical distribution plate and slides down along the guide chute to the lower horizontal distribution plate. The guide chute divides the raw material into multiple uniform material streams, while the distribution holes of the horizontal distribution plate further refine the material streams, making the raw material evenly distributed. During this process, the annular guide plate guides the raw material to flow towards the middle of the barrel, avoiding direct sliding down along the barrel wall. The elastic connecting frame buffers vibration and impact, while adapting to the impact of raw material feeding, ensuring the stable operation of the distribution structure. Through the double-layer distribution design, the material is divided and then refined step by step, effectively avoiding the concentrated accumulation of raw material and ensuring that the raw material is evenly distributed in the lower part of the barrel, creating favorable conditions for subsequent deep mixing.

[0018] The present invention is further configured such that: the elastic connecting frame includes two rubber blocks, the side of the rubber blocks near the connecting ring and the inner wall of the barrel are respectively bolted to the two, a telescopic rod is rotatably connected between the opposite sides of the two rubber blocks, and a spring is sleeved on the surface of the telescopic rod, both ends of the spring are bolted to the rubber blocks.

[0019] By adopting the above technical solution, and by setting up an elastic connecting frame, when the vibration motor is working, it drives the lower horizontal diversion plate to vibrate. The spring of the elastic connecting frame extends and retracts accordingly, and the telescopic rod extends and retracts synchronously to buffer the vibration impact, so as to avoid the vibration being directly transmitted to the cylinder wall. When the raw material feed fluctuates or impacts the diversion plate, the elastic deformation of the spring and telescopic rod can absorb the impact energy, maintain the horizontal state of the diversion plate, and ensure the stability of the diversion effect.

[0020] The present invention is further configured such that: a vibration motor is provided on both the front and rear sides inside the connecting ring, and the top of the vibration motor is bolted to the lower horizontal distribution plate.

[0021] By adopting the above technical solution, the vibration of the vibrating motor directly acts on the raw material flow, resulting in precise dispersion and preventing agglomerated raw materials from entering the mixing stage. This ensures that the subsequent mixing mechanism can fully mix individual particles of raw material, thereby improving the overall mixing uniformity.

[0022] The present invention is further configured such that: a fixing ring is provided at the top of the rotating frame, and a plurality of fixing rods are passed through the inside of the fixing ring in a ring shape, and the bottom of the fixing rods is bolted to the rotating frame; a hydraulic cylinder is bolted to the top of the fixing ring in a ring shape, and the hydraulic cylinder is located between two adjacent sets of fixing rods.

[0023] By adopting the above technical solution, the height of the shoe last mold can be precisely adjusted by the hydraulic cylinder to ensure uniform fit between it and the injection mold, thereby improving the injection molding accuracy of the shoe sole and adapting to the processing needs of shoe soles of different sizes and styles. In addition, the fixed ring rotates synchronously with the rotating frame, driving multiple shoe last molds and injection molds to align with the injection molding machine in sequence, realizing continuous injection molding production, greatly improving production efficiency, and adapting to batch production scenarios.

[0024] The invention is further configured such that: the bottom of the hydraulic cylinder extends to the bottom of the fixing ring and is bolted with a fixing plate, and a shoe last mold is snapped into the inside of the fixing plate, and the shoe last mold is used in conjunction with the injection mold.

[0025] By adopting the above technical solution, the shoe last mold and the fixed plate are connected and engaged, which not only ensures that the mold does not loosen or shift during the injection molding process, but also facilitates the quick replacement of shoe last molds of different styles, adapts to the production needs of multiple varieties, and reduces mold change time.

[0026] (III) Beneficial Effects Compared with the prior art, the present invention provides an integrated injection molding processing device for the sole of travel shoes, which has the following beneficial effects: This integrated injection molding processing device for the soles of tourist shoes employs a double-layer diversion structure in its upper material distribution mechanism. First, the material is divided into multiple uniform streams through the guide groove of the upper conical diversion plate. Then, it is further refined through the diversion holes of the lower horizontal diversion plate, preventing the material from accumulating and ensuring that the material is evenly distributed to the lower part of the barrel. This lays the foundation for subsequent deep mixing. Furthermore, through the synergistic action of the vibration motor and the elastic connecting frame, the diversion structure generates continuous micro-vibrations, which not only prevents the material from adhering and stagnating in the guide groove and diversion holes, but also efficiently breaks up material agglomerates, preventing agglomerated material from directly entering the mixing stage and causing insufficient mixing. The reciprocating mixing mechanism utilizes the axial pushing and longitudinal tumbling of the raw materials through the opposing spiral blades, along with the radial circulation and circumferential shearing generated by the tilting blades during their revolution and rotation. This combined motion creates a strong three-dimensional convection, diffusion, and shearing flow field within the barrel. This process effectively homogenizes raw material components of different densities and particle sizes, ensuring that masterbatches, additives, and other materials are fully and uniformly dispersed at the microscopic level. Furthermore, the mixing and preheating functions are integrated into one unit. Through the hollow shaft and hot air nozzles, low-temperature hot air is directly and uniformly introduced into the continuously tumbling raw material particles, enabling preheating during mixing and mixing during preheating. This achieves efficient heat exchange, ensuring that the raw material temperature is uniformly increased before entering the screw, effectively reducing the temperature gradient and avoiding thermal shock.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0030] Please see Figure 1-7 An integrated injection molding processing device for the sole of a travel shoe includes a rotating frame 1, with a plurality of injection molds 2 annularly bolted to the top of the rotating frame 1, and an injection molding machine 3 arranged on the front side of the rotating frame 1. The injection molding machine 3 is used in conjunction with the injection molds 2, and a material cylinder 4 is fixedly connected to the top of the injection molding machine 3. A deep mixing structure 5 is arranged inside the material cylinder 4. The deep mixing structure 5 includes an upper material leveling mechanism 51, which is bolted to the top of the inside of the cylinder 4. A connecting shaft 52 passes through the inside of the upper material leveling mechanism 51, and a reciprocating mixing mechanism 53 is bolted to the bottom of the connecting shaft 52. The bottom of the reciprocating mixing mechanism 53 is rotatably connected to the inner wall of the cylinder 4. Connecting sleeves 54 are fixedly sleeved on the top and bottom of the surface of the reciprocating mixing mechanism 53, and support rings 55 are fitted on the surface of the connecting sleeves 54. The support rings 55 are coaxially arranged with the connecting sleeves 54, and the two support rings 55 are... Several support rods 56 are bolted in a ring on one side of the material. Two inclined paddles 57 are bolted to the outer side of each support rod 56. The upper material distribution mechanism 51 employs a double-layer diversion structure. First, the upper diversion divides the raw material into multiple uniform streams, which are then further refined by the lower diversion, preventing material accumulation and ensuring uniform distribution to the lower part of the material cylinder 4. This lays the foundation for subsequent deep mixing. Furthermore, the upper material distribution mechanism 51 also has a vibration function, causing the diversion structure to generate continuous micro-vibrations, which can prevent the original material from accumulating. The material adheres and remains in the feed trough 513 and the diversion hole 514, which can efficiently break up the raw material agglomerates and prevent the agglomerated raw materials from directly entering the mixing stage, resulting in insufficient mixing. Through the axial pushing and longitudinal rolling of the oppositely rotating spiral blades 535 in the reciprocating mixing mechanism 53, the material is circulated up and down. The radial circulation and circumferential shearing generated by the inclined blades 57 during revolution and rotation, a strong three-dimensional convection, diffusion and shear flow field is formed in the feed cylinder 4 through this composite motion. It can generate a strong homogenization ability for raw material components with different densities and particle sizes, ensuring that the masterbatch, additives and other materials are fully and uniformly dispersed with the main material at the micro level. Furthermore, the mixing and preheating functions are integrated into one. Through the hollow shaft and hot air nozzle 11, low temperature hot air is directly and uniformly introduced into the constantly tumbling raw material particles, which can achieve preheating during mixing and mixing during preheating. This achieves efficient heat exchange, so that the temperature of the raw material is uniformly increased before entering the screw, effectively reducing the temperature gradient and avoiding thermal shock.

[0031] The reciprocating mixing mechanism 53 includes a first rotating shaft 531 and a second rotating shaft 532 arranged in parallel. A protective shell 533 is fitted between the tops of the first rotating shaft 531 and the second rotating shaft 532, and the first rotating shaft 531 passes through the interior of the protective shell 533. Transmission gears 534 are fixedly sleeved on the surfaces of both the first rotating shaft 531 and the second rotating shaft 532, and the two transmission gears 534 mesh with each other. Spiral blades 535 are welded to the surfaces of both the first rotating shaft 531 and the second rotating shaft 532, and the blades of the two spiral blades 535 rotate in opposite directions and are staggered. By setting up the reciprocating mixing mechanism 53, the servo motor 8 drives the first rotating shaft 531 to rotate through the connecting shaft 52. During rotation, the second rotating shaft 532 is driven to rotate synchronously in opposite directions by two meshing transmission gears 534, and the reverse spiral blades 535 on the surfaces of the first rotating shaft 531 and the second rotating shaft 532 rotate accordingly. The upper layer of raw material is pushed downward by the spiral blades 535, and the lower layer of raw material is lifted upward by the reverse spiral blades 535, forming an upper and lower convection circulation. The blades are staggered and continuously shear and stir the raw material during rotation, breaking up the density stratification and agglomeration of the raw material, and achieving uniform mixing of each component. The setting of the reverse spiral blades 535 constructs an upper and lower circulation channel for the raw material, effectively solving the defect of insufficient mixing of upper and lower layers in traditional single-shaft stirring, and ensuring uniform fusion of light and heavy raw materials and different components.

[0032] The bottom of the first rotating shaft 531 is rotatably connected to a bracket 6 via a bearing seat, and the outer side of the bracket 6 is bolted to the inner wall of the material cylinder 4. The top of the material cylinder 4 is bolted to a mounting bracket 7, and the top of the mounting bracket 7 is bolted to a servo motor 8. The output end of the servo motor 8 passes through the mounting bracket 7 and is bolted to the connecting shaft 52. The combination of the bearing seat and the bracket 6 provides stable support for the rotating shaft, preventing it from shaking or shifting during rotation. The servo motor 8 is connected to the first rotating shaft 531 via the connecting shaft 52, and its speed can be precisely adjusted according to the characteristics of the raw materials and mixing requirements, making it more adaptable.

[0033] Among them, a bushing 9 is fixedly sleeved on the bottom of the surface of the first rotating shaft 531, and several disturbance rods 10 are welded in a ring on the surface of the bushing 9. The outer side of the disturbance rods 10 rotates in contact with the inner wall of the material cylinder 4. By rotating the bushing 9 and the disturbance rods 10 synchronously with the first rotating shaft 531, the dead corner area at the bottom of the material cylinder 4 can be cleaned in a targeted manner to avoid the deposition of heavy raw materials and ensure that all raw materials in the material cylinder 4 can participate in the mixing, thereby further improving the mixing uniformity.

[0034] Both the first rotating shaft 531 and the second rotating shaft 532 are hollow inside, and several hot air nozzles 11 are fixedly connected to the surfaces of both shafts in an annular shape. Movable sleeves 12 are rotatably fitted onto the surfaces of both shafts, and these sleeves 12 are respectively connected to the first rotating shaft 531 and the second rotating shaft 532. A connecting pipe 13 is fixedly connected between opposite sides of the two movable sleeves 12. Hot air from the first rotating shaft 531 passes through the front movable sleeve 12 and the connecting pipe 13. The hot air enters the rear movable sleeve 12 and then the second rotating shaft 532, and finally exits from the hot air nozzles 11 that are evenly distributed on the surface of the shaft. This allows the hot air to be directly injected into the raw material flow that is violently agitated by the spiral blades 535 and the paddle blades 57, achieving dynamic and direct contact preheating. The hot air comes into full contact with the raw material particles that have a huge surface area and are constantly being renewed, resulting in extremely high heat exchange efficiency. This allows the preheating process to proceed simultaneously with the mixing process, ensuring uniform heating of the raw material and effectively avoiding local overheating or insufficient preheating, thereby reducing the heating load and energy consumption of the screw.

[0035] The upper material distribution mechanism 51 includes an upper conical distribution plate 511 and a lower horizontal distribution plate 512. The upper conical distribution plate 511 and the lower horizontal distribution plate 512 are bolted together. The surface of the upper conical distribution plate 511 is provided with several guide grooves 513 in an annular shape. The interior of the lower horizontal distribution plate 512 is provided with several distribution holes 514 in an annular shape. An annular guide plate 515 is bolted to the top edge of the lower horizontal distribution plate 512, and the other end of the annular guide plate 515 contacts the inner wall of the material cylinder 4. A connecting ring 516 is welded to the bottom edge of the lower horizontal distribution plate 512, and several elastic connecting brackets 517 are annularly bolted between the connecting ring 516 and the inner wall of the material cylinder 4. By setting the upper material distribution mechanism... In the material feeding mechanism 51, after the raw material enters the material cylinder 4, it first contacts the upper conical diverter plate 511 and slides down along the guide groove 513 to the lower horizontal diverter plate 512. The guide groove 513 divides the raw material into multiple uniform material flows, while the diversion holes 514 of the horizontal diverter plate further refine the material flow, making the raw material evenly distributed. During this process, the annular guide plate 515 guides the raw material to flow towards the middle of the material cylinder 4, avoiding direct sliding down along the cylinder wall. The elastic connecting frame 517 buffers vibration and impact, while adapting to the impact of raw material feeding, ensuring the stable operation of the diversion structure. Through the double-layer diversion design, the material is divided and then refined step by step, effectively avoiding the concentrated accumulation of raw material and ensuring that the raw material is evenly distributed in the lower part of the material cylinder 4, creating good conditions for subsequent deep mixing.

[0036] The elastic connecting frame 517 includes two rubber blocks 517a. The side of the rubber blocks 517a closest to the connecting ring 516 and the inner wall of the material cylinder 4 is bolted to both. A telescopic rod 517b is rotatably connected between the opposite sides of the two rubber blocks 517a. A spring 517c is sleeved on the surface of the telescopic rod 517b. Both ends of the spring 517c are bolted to the rubber blocks 517a. By setting the elastic connecting frame 517, when the vibration motor 14 is working, it drives the lower horizontal diversion plate 512 to vibrate. The spring 517c of the elastic connecting frame 517 extends and retracts accordingly, and the telescopic rod 517b extends and retracts synchronously to buffer the vibration impact and prevent the vibration from being directly transmitted to the cylinder wall of the material cylinder 4. When the raw material feed fluctuates or impacts the diversion plate, the elastic deformation of the spring 517c and the telescopic rod 517b can absorb the impact energy, maintain the horizontal state of the diversion plate, and ensure stable diversion effect.

[0037] Vibration motors 14 are installed on both the front and rear sides inside the connecting ring 516. The top of the vibration motor 14 is bolted to the lower horizontal diversion plate 512. The vibration of the vibration motor 14 directly acts on the raw material flow, resulting in precise dispersion and preventing agglomerated raw materials from entering the mixing stage. This ensures that the subsequent mixing mechanism can fully mix individual particles of raw material, thereby improving the overall mixing uniformity.

[0038] The rotating frame 1 has a fixed ring 15 at its top. Several sets of fixed rods 16 are threaded through the inside of the fixed ring 15 in a ring shape. The bottom of the fixed rods 16 are bolted to the rotating frame 1. A hydraulic cylinder 17 is bolted to the top of the fixed ring 15 in a ring shape. The hydraulic cylinder 17 is located between two adjacent sets of fixed rods 16. The height of the shoe last mold 19 can be precisely adjusted by the hydraulic cylinder 17 to ensure uniform fit between it and the injection mold 2, improve the injection molding accuracy of the shoe sole, and adapt to the processing needs of shoe soles of different sizes and styles. The fixed ring 15 rotates synchronously with the rotating frame 1, driving multiple shoe last molds 19 and injection molds 2 to align with the injection molding machine 3 in sequence, realizing continuous injection molding production, greatly improving production efficiency, and adapting to batch production scenarios.

[0039] The bottom of the hydraulic cylinder 17 extends to the bottom of the fixing ring 15 and is bolted to a fixing plate 18. The shoe last mold 19 is snapped into the inside of the fixing plate 18. The shoe last mold 19 is used in conjunction with the injection mold 2. By snapping the shoe last mold 19 into the fixing plate 18, it is ensured that the mold does not loosen or shift during the injection process. It also facilitates the quick replacement of different styles of shoe last molds 19, adapting to the production needs of multiple varieties and reducing mold change time.

[0040] The working principle of this embodiment is as follows: The finished shoe upper is fitted onto the shoe last mold 19, and the two are snapped onto the fixing plate 18. Then, when the hydraulic cylinder 17 descends, the shoe upper is aligned with the injection mold 2. The raw material is fed in through the top inlet of the material cylinder 4, and the servo motor 8 and the vibration motor 14 are started. The servo motor 8 drives the first rotating shaft 531 to rotate through the connecting shaft 52. The meshing transmission gear 534 drives the second rotating shaft 532 to rotate synchronously in the opposite direction. The reciprocating mixing mechanism 53 is activated. Upon initial movement, the raw material enters the feed cylinder 4 and first contacts the upper conical distribution plate 511 of the upper material distribution mechanism 51. It is then divided into multiple streams along the guide chute 513 and slides down to the lower horizontal distribution plate 512. After further refinement through the distribution holes 514, the material is evenly dispersed. Simultaneously, the vibration motor 14 drives the lower horizontal distribution plate 512 to vibrate. Combined with the buffering effect of the elastic connecting frame 517, this breaks up any agglomerates of raw material, preventing adhesion within the guide chute 513 and distribution holes 514, resulting in even dispersion. The raw materials fall into the reciprocating mixing mechanism 53 area. The reverse spiral blades 535 rotate to form an upward and downward convection. The upper layer of raw materials is pushed downward and the lower layer of raw materials is lifted upward. Meanwhile, the inclined blades 57 on the outside of the support rod 56 simultaneously generate radial circulation and circumferential shear, constructing a three-dimensional flow field to achieve deep mixing of the raw materials. The disturbance rod 10 at the bottom of the first rotating shaft 531 rotates with the shaft to clean the raw materials at the bottom of the barrel 4 and prevent sedimentation. During the mixing process, hot air enters the first rotating shaft 531 and enters the rear movable sleeve 12 through the connecting pipe 13. It is then sprayed out from the annularly distributed hot air nozzles 11 through the hollow first rotating shaft 531 and the second rotating shaft 532, making full contact with the tumbling raw materials to achieve simultaneous mixing and preheating. Finally, the mixed and preheated raw materials enter the injection molding machine 3. The rotating frame 1 drives the injection mold 2 and the shoe last mold 19 to rotate sequentially to the rear of the injection molding machine 3. The injection molding machine 3 injects the raw materials into the closed cavity. After the raw materials cool and solidify, the integrated injection molding of the sole and the upper is completed.
