Description

Technical Field

[0001] This utility model relates to the field of shoe sole forming machine, and in particular to a row of vertical shoe sole forming machine unit. Background Technology

[0002] A foam molding machine is an industrial device used to process foam raw materials into foam products of specific shapes. Its core principle is to use processes such as heating, pressurizing, and cooling to make the foam particles expand and fill the mold cavity, and finally solidify to form a lightweight, porous foam product.

[0003] A Chinese invention patent with publication number CN109605643A discloses a vertical semi-automatic popcorn shoe sole forming machine, including a worktable, a mounting frame, a control panel, a fixed mold fixing frame, a moving mold fixing frame, a hydraulic cylinder, a material barrel, guide pillars, a steam control device, a cooling water control device, and an air control device. The worktable is installed on one side of the mounting frame, and a hydraulic cylinder fixing frame is provided at the upper end of the mounting frame. The hydraulic cylinder is fixed on the hydraulic cylinder fixing frame, and the telescopic part of the hydraulic cylinder fixing frame is fixed on the moving mold fixing frame. The two ends of the guide pillar are respectively fixed on the fixed mold fixing frame and the hydraulic cylinder fixing frame. The hydraulic cylinder pushes the moving mold fixing frame to move up and down on the guide pillar. The moving mold is installed on the moving mold fixing frame, and the fixed mold is installed on the fixed mold fixing frame. When the mold is closed, a mold cavity is formed between the moving mold and the fixed mold. TUP foaming particles are injected into the mold cavity through the material barrel through a material gun, and then heated by steam and cooled to form a popcorn shoe sole, realizing semi-automatic production. However, the above-mentioned shoe sole forming machine has the following defects in actual use:

[0004] 1. Existing popcorn shoe sole forming machines generally adopt an independent single-machine design. Each machine needs to be configured with a complete frame, hydraulic system, cooling pipeline and material distribution device, resulting in high structural repetition and large material consumption, which indirectly increases production costs. At the same time, the single machine needs to complete the processes of raw material heating, mold cooling and cavity vacuuming in sequence during the production process. There is a long waiting time between each process. Different machines cannot achieve process connection and intermittent operation, resulting in low energy and equipment resource utilization. In addition, traditional single machines require dedicated personnel to monitor them in real time. When multiple machines are produced, an equal number of operators are required, which leads to a significant increase in labor costs. Moreover, the independent layout of single machines makes the workshop pipeline messy and difficult to maintain.

[0005] 2. Existing popcorn shoe sole forming machines require cooling of the formed shoe soles after mold closing. To ensure cooling efficiency, cooling water pipes need to be connected at both the fixed mold and the moving mold to cool the formed shoe soles. However, this shoe sole forming machine only uses simple drainage holes and drainage pipes to discharge cooling water, which makes it easy for water to accumulate outside the mold, affecting the subsequent shoe sole heating and forming effect.

[0006] 3. Existing shoe sole forming machines are only equipped with a single material cylinder and can only achieve single-sided material feeding. They cannot meet the diverse material feeding needs of shoe soles with special structures such as double-sided feeding, two-color upper and lower parts, sandwich panels, or the addition of carbon sheets, thus limiting the adaptability of the equipment. Summary of the Invention

[0007] The technical problem to be solved by this utility model is to provide a vertical shoe sole forming machine unit that addresses the shortcomings of the prior art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a row-type vertical shoe sole forming machine unit, including an outer frame, at least two vertical shoe sole forming machines arranged in a row within the outer frame, and a hydraulic station. Each vertical shoe sole forming machine includes a frame, a fixed mold module and a moving mold module arranged axially correspondingly on the frame, a hydraulic cylinder for driving the moving mold module to approach or move away from the fixed mold module, an air distribution pipe, a steam distribution pipe, a cooling water distribution pipe, and a main drain pipe. Each fixed mold module and moving mold module has several corresponding fixed mold mounting seats and moving mold mounting seats, and each fixed mold mounting seat and moving mold mounting seat is equipped with corresponding fittings. The machine comprises a shoe sole punch and a shoe sole die, which, after being closed, form a shoe sole forming cavity for molding the shoe sole. The outer frame is equipped with a hydraulic control structure that uses a hydraulic station to control the hydraulic cylinders on each vertical shoe sole forming machine. The hydraulic control structure includes a hydraulic distribution valve corresponding to one side of each set of vertical shoe sole forming machines, a main hydraulic input pipe and a main hydraulic output pipe connecting the hydraulic station to each set of hydraulic distribution valves, and a sub-hydraulic input pipe and a sub-hydraulic output pipe connecting each set of hydraulic distribution valves to the corresponding hydraulic cylinders. The hydraulic station controls the mold opening or closing action of each set of vertical shoe sole forming machines individually through the hydraulic distribution valves.

[0009] By adopting the above technical solution, at least two vertical shoe sole forming machines arranged in the same row are integrated within the outer frame, and a unified hydraulic station and hydraulic control structure are set up. The hydraulic control structure includes a hydraulic distribution valve corresponding to each group of vertical shoe sole forming machines, as well as a main hydraulic input / output pipe connecting the hydraulic station and the hydraulic distribution valve, and a secondary hydraulic input / output pipe connecting the hydraulic distribution valve and the hydraulic cylinder. This allows the hydraulic station to individually control the hydraulic cylinder action of each vertical shoe sole forming machine through the hydraulic distribution valve, realizing independent mold opening or closing for each unit. This addresses the problems of high structural repetition, high material consumption, long standby time between processes, and low equipment resource utilization caused by traditional single-machine independent frame and hydraulic system configurations. By sharing the outer frame and hydraulic station among multiple units, redundant frames and hydraulic system components are reduced, lowering material consumption and production costs. In single-machine production, the individual control of each unit via hydraulic distribution valves enables asynchronous operation of multiple units, allowing different units to operate at different stages such as heating, cooling, and part removal. This avoids equipment idleness caused by the traditional single-machine system requiring all processes to be completed sequentially, improving equipment and energy utilization. The layout of units arranged in the same row, combined with unified control, allows a single operator to manage multiple machines simultaneously, reducing labor requirements. Furthermore, the integrated design of the outer frame consolidates the previously messy piping layout of individual machines, reducing the difficulty of maintaining workshop piping.

[0010] The aforementioned vertical shoe sole forming machine unit can be further configured as follows: the fixed mold module and the moving mold module have a fixed mold cavity and a moving mold cavity inside; the air distribution pipe is used to supply air to the fixed mold cavity and the moving mold cavity; the steam distribution pipe is used to supply steam to the fixed mold cavity and the moving mold cavity; the cooling water distribution pipe is used to supply cooling water to the fixed mold cavity and the moving mold cavity; the fixed mold module is provided with a fixed mold drainage mechanism to discharge the cooling water in the fixed mold cavity; the moving mold module is provided with a moving mold drainage mechanism to discharge the cooling water in the moving mold cavity; a hollow main drainage pipe is provided inside the outer frame on one side corresponding to the main drainage pipe; one end of the main drainage pipe extends out of the outer frame and is provided with a main drainage connector; one end of the main drainage pipe at each set of vertical shoe sole forming machines receives the cooling water discharged by the fixed mold drainage mechanism and the moving mold drainage mechanism, and the other end is connected to the main drainage pipe.

[0011] By adopting the above technical solution, a mold cavity and a moving mold cavity are set inside the mold-fixed module and the moving mold module, respectively. Air, steam, and cooling water are supplied to the cavities through air distribution pipes, steam distribution pipes, and cooling water distribution pipes. Mold-fixed drainage mechanisms and moving mold drainage mechanisms are respectively installed in the mold-fixed module and the moving mold module. Simultaneously, a main drainage pipe is installed inside the outer frame, allowing the main drainage pipe of each vertical shoe sole forming machine to collect the cooling water discharged by the mold-fixed and moving mold drainage mechanisms and discharge it uniformly. The mold-fixed and moving mold drainage mechanisms respectively direct the discharge of cooling water from their respective cavities, preventing cooling water from stagnating inside the mold. The setting of the main drainage pipe will... The centralized drainage system of multiple vertical shoe sole forming machines replaces the messy pipeline layout of traditional single-machine independent drainage, reducing the difficulty of workshop pipeline maintenance. Air, steam, and cooling water are precisely delivered to the corresponding cavities through distribution pipes, realizing independent control of heating, cooling, demolding and other processes during shoe sole forming. Steam can be evenly applied to the shoe sole forming cavity to fully expand the foam particles, cooling water can quickly remove heat to achieve solidification, and air delivery helps to reduce resistance during demolding. The three work together to improve the quality and efficiency of shoe sole forming. At the same time, the centralized drainage design reduces the interference of water accumulation outside the mold on the heating process, ensuring the continuous and stable operation of the equipment.

[0012] The aforementioned vertical shoe sole forming machine unit can be further configured as follows: two material distribution devices are provided on one side of the frame. The material distribution devices are respectively connected to the shoe sole punch and / or shoe sole die and are connected to the shoe sole forming cavity. The material distribution device includes a material distribution tank, a return material assembly, and an infeed distribution air outlet. The material distribution tank includes a tank body, a material infeed pipe located above the tank body, and several material outlets located at the lower end of the tank body. The return material assembly includes a return material chamber and a return material pipe. One end of the return material pipe is connected to the tank body, and the other end is connected to the return material chamber. A three-way valve is provided at the bottom of the return material chamber. One end of the three-way valve is connected to the infeed distribution air outlet, one end is connected to the return material chamber, and one end is connected to the tank body.

[0013] The above technical solution involves installing two material distribution devices on one side of the frame. Each device includes a material distribution tank, a return material assembly, and an infeed distribution exhaust. The material distribution tank receives raw materials through a material inlet pipe and connects to the shoe sole punch and / or shoe sole die via an outlet connector. The return material assembly guides excess material from the tank back to the return chamber through a return pipe. A three-way valve at the bottom of the return chamber controls the material flow, achieving precise material supply and recovery. The two material distribution devices can be independently connected to the shoe sole punch and / or shoe sole die. This is particularly useful when producing two-tone, clip-on shoes. When making soles with special structures such as multi-layer soles, two material distribution devices can simultaneously supply materials to different areas of the sole forming cavity to meet diverse material supply needs. The material return component allows excess material not injected into the cavity to be recovered to the material distribution tank through the material return pipe and material return chamber, reducing raw material waste. The multi-directional function of the feed three-way valve can flexibly switch the feeding path and adapt to single-sided or double-sided feeding modes, improving the equipment's adaptability to different sole structures. Several discharge joints at the bottom of the material tank can correspond to multiple sole forming cavities, supporting simultaneous feeding of multiple sets of molds and improving production efficiency.

[0014] The aforementioned vertical shoe sole forming machine unit can be further configured as follows: the shoe sole punch or shoe sole die is provided with a mold inlet that connects the cooling water distribution pipe to the mold cavity; the mold drainage mechanism includes a mold water storage cavity formed by the shoe sole punch or shoe sole die on a mold mounting base, a mold drainage hole and a lower drainage gap located at the mold mounting base and connected to the outside of the mold module, and a mold drainage drive assembly located on one side of the mold drainage hole; the output end of the mold drainage drive assembly is connected to a mold drainage pin; the mold water storage cavity is located at the lower part of the mold cavity, and the mold drainage holes are all connected to the mold water storage cavity; the mold drainage holes are respectively connected to the lower drainage gap and the mold water storage cavity; the mold drainage drive assembly drives the mold drainage pin to block or open the mold drainage hole.

[0015] The above technical solution involves setting a mold inlet on the shoe sole punch or die to connect the cooling water distribution pipe to the mold cavity. A mold drainage mechanism is constructed within the mold module, consisting of a mold water storage cavity, a mold drainage hole, a lower drainage gap, and a mold drainage drive assembly. The mold water storage cavity is located at the lowest point of the mold cavity and is connected to the mold drainage hole, which in turn connects to the lower drainage gap. The mold drainage drive assembly drives the mold drainage pin to control the sealing or opening of the mold drainage hole. The low position of the mold water storage cavity allows cooling water to collect naturally, preventing water from pooling within the mold cavity. The mold drainage drive assembly controls the action of the mold drainage pin to precisely open the drainage channel after the cooling process, allowing the cooling water in the water storage chamber to be discharged in an orderly manner through the mold drainage hole and the lower drainage gap, preventing the cooling water from stagnating inside the mold. The selective sealing function of the drainage hole can keep the mold cavity sealed during the heating process to avoid heat loss, while the directional flow design during drainage reduces the contact between the cooling water and the outside of the mold, reducing the risk of water accumulation on the outside of the mold and ensuring that the mold surface is dry during subsequent heating and molding, thereby ensuring the uniform heating of the shoe sole and the stability of the molding effect.

[0016] The aforementioned vertical shoe sole forming machine unit can be further configured as follows: a mold sink plate is provided above the mold drainage hole of the mold module, the mold sink plate divides the mold cavity into a mold water storage cavity and a mold overflow cavity, an overflow baffle is provided on the side of the mold module corresponding to the mold sink plate, an overflow drainage cavity exists between the overflow baffle and the mold module, an overflow drainage pipe is connected in the overflow drainage cavity, the overflow drainage pipe is connected to the main drainage pipe, a plurality of overflow drainage holes are opened on the overflow baffle to conduct the mold overflow cavity and the overflow drainage cavity, the overflow drainage holes are located above the mold sink plate, the mold drainage driving component is a mold drainage cylinder, the mold drainage cylinder is installed outside the mold module and is linked with a mold drainage pin, the mold drainage pin passes through the overflow baffle and enters or exits the mold drainage hole.

[0017] Using the above technical solution, a mold sink plate is installed above the mold drainage hole of the mold module, dividing the mold cavity into a lower mold water storage cavity and an upper mold overflow cavity. An overflow baffle is installed on the side of the mold sink plate, forming an overflow drainage cavity between the overflow baffle and the mold module. The overflow drainage cavity is connected to the main drainage pipe through an overflow drainage pipe. Several overflow drainage holes are opened on the overflow baffle above the mold sink plate to connect the mold overflow cavity and the overflow drainage cavity. At the same time, a mold drainage cylinder is used as the mold drainage drive component. It is installed outside the mold module and linked to the mold drainage pin. After the mold drainage pin passes through the overflow baffle, it can block or open the mold drainage hole. The partition design of the mold sink plate causes the cooling water to flow in layers within the mold cavity. The bottom layer of cooling water collects in the mold water storage cavity and is actively discharged through the mold drainage hole, while the excess cooling water in the upper layer overflows. The water flows into the solid mold overflow cavity and then into the overflow drain cavity through the overflow drain hole, forming a dual drainage path that significantly improves drainage thoroughness and prevents overflow. The overflow drain hole is located above the solid mold countersink plate, allowing for rapid drainage of accumulated water when the water storage cavity is not draining in time. This prevents cooling water from overflowing the countersink plate and seeping into other areas of the mold. The external design of the solid mold drainage cylinder avoids the problems of traditional built-in drive components occupying cavity space or having their lifespan affected by high temperatures. Its structure, which drives the solid mold drainage pin through the overflow baffle, allows for precise control of the opening and closing timing of the drain hole. During the heating process, it remains sealed to reduce heat loss, and after the cooling process, it quickly opens to drain. At the same time, the cooperation between the pin and the overflow baffle improves the sealing performance of the drain hole, preventing steam leakage during heating. The connection between the overflow drain cavity and the main drain pipe allows the overflow path and the main drainage path to share the total drainage system, avoiding the need for additional piping.

[0018] The aforementioned vertical shoe sole forming machine unit can be further configured as follows: a water baffle plate and a water baffle driving mechanism that drives the water baffle plate to move closer to or away from the fixed mold module are provided on the side of the frame corresponding to the fixed mold module. The water baffle driving mechanism can drive the water baffle plate to stay below the lower gap. The side of the water baffle plate facing the fixed mold module has a cavity, and a water baffle plate drainage hole is provided in the cavity. The water baffle plate drainage hole and the overflow drainage pipe are both connected to the main drainage pipe.

[0019] The shoe sole punch or shoe sole die is provided with a mold transfer inlet that connects the cooling water distribution pipe to the mold transfer cavity. The mold transfer drainage mechanism includes a mold transfer drainage hole on the mold transfer module and a mold transfer frame base plate located at the corresponding mold transfer mounting seat of the mold transfer module. The mold transfer inlet is located on the mold transfer frame base plate and communicates with the mold transfer cavity. The mold transfer drainage hole is located on one side of the mold transfer module and its cross-sectional height is lower than that of the mold transfer inlet. The mold transfer frame base plate is inclined toward the direction of the mold transfer drainage hole. The mold-moving drainage hole is connected to the main drainage pipe. The mold-moving module is provided with a mold-moving cover plate corresponding to the mold-moving drainage hole. The mold-moving cover plate and the mold-moving module cooperate to form a mold-moving drainage cavity. The mold-moving drainage hole is located at the bottom of the mold-moving drainage cavity. The mold-moving drainage cavity is located below the bottom plate of the mold-moving frame. The bottom plate of the mold-moving frame is covered above the mold-moving drainage cavity. The bottom plate of the mold-moving frame is provided with a plurality of mold-moving water passage holes corresponding to the mold-moving drainage cavity to connect the mold-moving cavity and the mold-moving drainage cavity.

[0020] Using the above technical solution, by setting a baffle plate and a baffle drive mechanism that drives it to move closer or further away from the fixed mold module on one side of the frame, the baffle plate can stay below the lower gap. Cooling water is collected in the cavity on the side of the baffle plate facing the fixed mold module. The drain hole of the baffle plate in the cavity is connected to the main drain pipe along with the overflow drain pipe. Simultaneously, in the mold-moving module, the mold-moving inlet is set on the bottom plate of the mold-moving frame and communicates with the mold-moving cavity. The mold-moving drain hole is set on one side of the mold-moving module and its cross-sectional height is lower than that of the mold-moving inlet. The bottom plate of the mold-moving frame is inclined towards the mold-moving drain hole. A mold-moving drain cavity is set below the bottom plate of the mold-moving frame. The bottom plate connects the mold-moving cavity and the mold-moving drain cavity through several mold-moving water passages. The mold-moving drain hole at the bottom of the mold-moving drain cavity is connected to the main drain pipe. Enclosed by the mold transfer cover plate, the concave structure of the baffle plate can effectively receive the cooling water discharged from the lower gap, avoiding direct dripping and causing water accumulation on the workshop floor and dampness on the equipment. The connection between the baffle plate's drainage hole and the main drainage pipe realizes the sealing of the drainage path. With the help of the baffle plate drive mechanism, the baffle plate can be moved away during non-drainage processes, which not only ensures the operating space but also improves environmental safety. In the mold transfer module, the inclined mold transfer frame bottom plate combined with the mold transfer drainage hole lower than the water inlet uses gravity to make the cooling water in the mold transfer cavity flow into the lower mold transfer drainage cavity through the mold transfer water passage, and then discharge through the drainage hole, realizing layered drainage to solve the residue problem. The mold transfer drainage cavity is integrated under the mold transfer frame bottom plate and is enclosed by the cover plate, avoiding interference between the drainage path and other components.

[0021] The aforementioned vertical shoe sole forming machine unit can be further configured as follows: the mold moving module is connected to a mold moving exhaust valve communicating with the mold moving cavity; the mold fixing module is connected to a mold fixing exhaust valve communicating with the mold fixing cavity; a mold moving tee is connected to the mold moving drainage hole; one end of the mold moving tee is communicating with the mold moving drainage hole, one end is connected to the mold moving exhaust valve, and the other end is connected to the mold moving drainage valve; the mold moving drainage valve is connected to the main drainage pipe through a flexible hose.

[0022] Using the above technical solution, the mold transfer vent valve and the mold vent valve can respectively discharge air or steam from the mold transfer cavity and the mold vent cavity, avoiding gas from hindering the uniform distribution of cooling water in the cavity, ensuring that the cooling medium fully contacts the inner wall of the mold to improve cooling efficiency. The mold transfer tee integrates the mold transfer drain hole, the mold transfer vent valve and the mold transfer drain valve into one unit, so that the venting and drainage paths can be controlled by the same interface. During the cooling stage, the mold transfer drain valve can be opened to allow cooling water to be discharged into the main drain pipe through the hose, while the gas is discharged through the mold transfer vent valve. During the non-draining stage, the drain valve can be closed and the gas can be discharged separately through the vent valve.

[0023] The aforementioned vertical shoe sole forming machine unit can be further configured such that: at least one of the shoe sole punch and shoe sole die has a feeding gun connected to a material distribution device; the feeding gun is connected to the shoe sole forming cavity; all shoe sole punches are installed in the fixed mold mounting base; all shoe sole dies are installed in the moving mold mounting base; the shoe sole punch includes a punch support, a punch base, and a punch connecting plate; the punch base is provided with a punch core; the punch support has a fixed mold water inlet that connects a cooling water distribution pipe to the fixed mold cavity; the punch base and the fixed mold mounting base cooperate to form a fixed mold water storage cavity. The shoe sole mold includes a mold support, a mold base, and a mold connecting plate. The mold base has a mold cavity. The mold support has a cooling water distribution pipe and a mold inlet that communicates with the mold cavity. A cooling spray assembly is installed at one end of the mold support facing the mold base. The cooling spray assembly includes a water pipe connector connected to the cooling water distribution pipe, multiple rows of longitudinal water pipes, and horizontal drain pipes. The water pipe connector passes through the mold inlet and connects to the longitudinal water pipes or the horizontal drain pipes. The longitudinal water pipes and the horizontal drain pipes are interconnected, and a nozzle is provided at one end facing the mold connecting plate.

[0024] By adopting the above technical solution, the direct connection between the feeding gun and the shoe sole molding cavity shortens the material conveying distance, reduces pressure loss and flow resistance, ensures that the material fills the cavity quickly and evenly, and improves molding efficiency and product consistency. The mold water storage cavity formed by the cooperation of the punch base and the mold mounting seat, combined with the mold water inlet on the punch bracket, allows the cooling water to form a stable water storage space on the punch side, ensuring uniform cooling of the punch core. The cooling spray assembly on the die side, through the cross distribution of multiple rows of longitudinal water pipes and transverse drainage pipes, combined with nozzles facing the die connecting plate, transforms the cooling water into multi-directional spray water flow, increases the contact area with the inner wall of the die cavity, and solves the problem of large local temperature difference in traditional die cooling. At the same time, the interconnection design of the longitudinal and transverse water pipes ensures that the water pressure of each nozzle is uniform, further improving cooling efficiency and mold temperature consistency, and reducing the risk of warping and deformation during the shoe sole molding process.

[0025] The aforementioned vertical shoe sole forming machine unit can be further configured as follows: the fixed mold module has multiple fixed mold mounting seats arranged in the same row on the fixed mold module; the moving mold module has multiple moving mold mounting seats arranged in the same row on the moving mold module; the outer frame is provided with an outer protective plate; the outer protective plate has a working window at the initial position of the moving mold module; and the outer frame has a worktable on one side corresponding to the working window.

[0026] By adopting the above technical solution, multiple fixed mold mounting seats and moving mold mounting seats arranged in the same row can realize the synchronous installation and molding of multiple sets of shoe sole molds, significantly improving the product output per unit time and meeting the needs of mass production. The outer protective plate can effectively isolate the internal moving parts of the equipment from the external operating environment, reduce the risk of operators coming into contact with dangerous areas, and improve the safety of equipment operation. The design of the working window corresponding to the initial position of the moving mold module allows operators to conveniently change molds, replenish raw materials, or pick up and put away products through the window when the moving mold module is not in working state, avoiding the cumbersome operation caused by frequent opening and closing of the overall protective plate. The addition of the worktable provides a stable temporary placement platform for the operation process, making it convenient to access tools, semi-finished products, or auxiliary materials nearby, reducing the movement path of operators, further optimizing the work process, and improving overall production efficiency.

[0047] like Figures 1-19 As shown, a row of vertical shoe sole forming machine units includes an outer frame 1, at least two vertical shoe sole forming machines 2 arranged in a row within the outer frame 1, and a hydraulic station 3. Each vertical shoe sole forming machine 2 includes a frame 21, a fixed mold module 4 and a moving mold module 5 arranged axially on the frame 21, a hydraulic cylinder 22 for driving the moving mold module 5 to move closer to or away from the fixed mold module 4, a guide shaft 23, an air distribution pipe 24, a steam distribution pipe 25, a cooling water distribution pipe 26, and a main... The drain pipe 27, the fixed mold module 4, and the moving mold module 5 are each provided with several corresponding fixed mold mounting seats 41 and moving mold mounting seats 51. Each fixed mold mounting seat 41 and moving mold mounting seat 51 is equipped with a corresponding matching sole punch 6 and sole concave mold 7. After the sole punch 6 and sole concave mold 7 are closed, they cooperate to form a sole forming cavity 60 for forming the sole. The outer frame 1 is provided with a hydraulic control structure that uses a hydraulic station 3 to control the operation of the hydraulic cylinders 22 on each vertical sole forming machine 2. Figure 3 As shown, the hydraulic control structure includes a hydraulic distribution valve 31 corresponding to one side of each set of vertical shoe sole forming machines 2, a main hydraulic input pipe 32 and a main hydraulic output pipe 33 connecting the hydraulic station 3 to each set of hydraulic distribution valves 31, and a branch hydraulic input pipe 34 and a branch hydraulic output pipe 35 connecting each set of hydraulic distribution valves 31 to the corresponding hydraulic cylinders 22.

The air distribution pipe 24 is used to supply air to the fixed mold cavity 40 and the moving mold cavity 50, and the steam distribution pipe 25 is used to supply steam to the fixed mold cavity 40 and the moving mold cavity 50. The cooling water distribution pipe 26 is used for... Cooling water is supplied to the fixed mold cavity 40 and the moving mold cavity 50. The fixed mold module 4 is equipped with a fixed mold drainage mechanism to discharge the cooling water in the fixed mold cavity 40, and the moving mold module 5 is equipped with a moving mold drainage mechanism to discharge the cooling water in the moving mold cavity 50. The outer frame 1 is equipped with a hollow main drain pipe 14 on one side corresponding to the main drain pipe 27. One end of the main drain pipe 14 extends out of the outer frame 1 and is equipped with a main drain connector 141. One end of the main drain pipe 27 at each set of vertical shoe sole forming machines 2 receives the cooling water discharged by the fixed mold drainage mechanism and the moving mold drainage mechanism, and the other end is connected to the main drain pipe 14. Thus, the cooling water discharged by each set of vertical shoe sole forming machines 2 is recycled as a whole through the main drain pipe 14 inside the outer frame 1 and the circulation system is used to realize the circulation of cooling water.

[0048] like Figure 1, 2 As shown, there are three fixed mold mounting seats 41 on the fixed mold module 4, and the three fixed mold mounting seats are arranged in the same row on the fixed mold module 4. There are three moving mold mounting seats 51 on the moving mold module 5, and the three moving mold mounting seats are arranged in the same row on the moving mold module 5. The outer frame 1 is provided with an outer protective plate 11. The outer protective plate 11 has a working window 12 at the initial position of the moving mold module 5. The outer frame 1 has a worktable 13 on one side corresponding to the working window 12. By setting a row of shoe sole punches 6 and shoe sole dies 7 in each set of vertical shoe sole forming machines 2, the workers can directly stand on the worktable 13 and install or unload parts on the shoe sole punches 6 or shoe sole dies 7 installed on the moving mold module 5 through the working window 12. The single-row structure makes the workers' work more convenient, and they can complete the work with just a slight bend.

[0049] like Figures 4-7 As shown, each frame 21 has two material distribution devices 8 on one side. The material distribution devices 8 are respectively connected to the shoe sole punch 6 and / or shoe sole die 7 and are connected to the shoe sole forming cavity 60. The material distribution device 8 includes a material distribution tank, a material return assembly, and a material distribution air outlet 83. The material distribution tank includes a tank body 81, a material inlet pipe 811 located above the tank body 81, and several material outlet joints 812 located at the lower end of the tank body 81.

[0053] like Figures 1-19As shown, this utility model discloses a series of vertical shoe sole forming machine units. The vertical shoe sole forming machines 2 within the outer frame 1 can be controlled and processed simultaneously in single or multiple groups as needed. Taking multiple vertical shoe sole forming machines 2 as an example, the worker only needs to stand on the workbench 13 and, through the work window 12, install or unload parts onto the shoe sole punch 6 or shoe sole concave mold 7 mounted on the moving mold module 5. The PLC control system controls the moving mold module and fixed mold combination of multiple vertical shoe sole forming machines to inject TPU foam particles into the mold cavity, heat the TPU foam particles with steam, cool and form the heated shoe sole, and then vacuum the inside of the mold cavity. After completing the above operations, the mold is opened and the formed shoe is removed. In this series of operations, the PLC controls the completion time of each process in multiple machines, allowing for staggered connections between the processes of multiple vertical shoe sole forming machines. This enables a single manager to simultaneously control and manage the production of multiple machines, maximizing production structure optimization, saving production costs. The entire unit has a simple structure and is easy to operate. The processes of each machine can be interconnected, reducing the installation of multiple pieces of equipment, reducing production and operating costs, ensuring rational resource utilization, guaranteeing optimal equipment performance, and allowing one worker to operate multiple machines simultaneously, thus reducing labor costs for the enterprise. The individual vertical shoe sole forming machine in this unit has the following steps during operation:

[0054] S1: Start the hydraulic cylinder 22 to drive the moving mold module 5 to move along the guide shaft 23 towards the fixed mold module 4 until the shoe sole punch 6 and the shoe sole die 7 are completely closed to form a sealed shoe sole forming cavity 60.

[0055] Material supply mode selection (taking "two-tone sole" as an example):

[0056] The material distribution device 8 is activated: the upper material distribution device 8 injects light-colored foamed granules into the material distribution tank 81 through the material feed pipe 811, and the lower material distribution device 8 injects dark-colored foamed granules.

[0057] Open the feed three-way valve 822 to connect the feed tank 81 and the feed distribution air outlet 83. The material is injected into the top of the cavity of the shoe sole punch 6 and the bottom of the cavity of the shoe sole die 7 through the discharge connector 812 and the feed gun 70 respectively.

[0058] After the material feeding is completed, close the feed three-way valve 822, start the return component 82, and recover the excess material;

[0059] S2: Open the mold venting valve 48 and the mold moving venting valve 55 to expel the original air in the cavity, ensuring that the steam fully contacts the material and causes the foamed particles to expand and fill the shoe sole molding cavity 60.

[0060] Open the valve on the steam distribution pipe 25 to input high-temperature steam into the fixed mold cavity 40 and the moving mold cavity 50;

[0061] After heating for the set time, close the steam distribution pipe valve 25 to stop heating;

[0062] S3: Open the valve of the cooling water distribution pipe 26, and the cooling water flows into the fixed mold cavity 40 and the moving mold cavity 50 through the fixed mold inlet 401 and the moving mold inlet 501 respectively;

[0063] When the cooling spray assembly 10 on the mold moving side is activated, cooling water enters the longitudinal water pipe 102 and the transverse drain pipe 103 through the water pipe joint 101, and is evenly sprayed onto the surface of the concave mold cavity 721 or the surface of the convex mold core 621 through the nozzle 104 to accelerate the cooling and solidification of the shoe sole; the cooling water in the fixed mold cavity 40 flows into the lower fixed mold water storage cavity 402 along the fixed mold sink plate 45.

[0064] After cooling is completed, the hydraulic cylinder 22 is activated to drive the mold moving module 5 to move away from the fixed mold module 4 along the guide shaft 23. The water blocking drive mechanism 9 drives the water blocking plate 91 to stop below the lower drain gap 43. The fixed mold drain cylinder 44 is activated to drive the fixed mold drain pin 441 to exit the fixed mold drain hole 42. The cooling water flows into the cavity of the water blocking plate 91 through the fixed mold drain hole 42 and the lower drain gap 43, and then flows into the main drain pipe 27 through the water blocking plate drain hole 911.

[0065] If the water level in the mold cavity 40 exceeds the height of the mold sink plate 45, the excess cooling water flows into the overflow drain cavity 404 through the overflow drain hole 461 and into the main drain pipe 27 through the overflow drain pipe 47.

[0066] The cooling water in the mold transfer cavity 50 flows along the inclined mold transfer frame bottom plate 53 and flows into the mold transfer drainage cavity 502 below through the mold transfer water passage 531;

[0067] After the cooling water is collected in the mold transfer drainage chamber 502, it flows into the main drainage pipe 27 through the mold transfer drainage hole 52, the mold transfer tee pipe 56, and the mold transfer drainage valve 57.

[0068] During drainage, the mold removal drain valve 57 and the mold removal vent valve 55 remain closed;

[0069] S4: The water-blocking drive mechanism 9 drives the water-blocking plate 91 away from the fixed mold module 4 to avoid affecting the next mold closing;

[0070] The mold drainage cylinder 44 drives the mold drainage pin 441 to reset, blocking the mold drainage hole 42.

[0071] Open the air distribution pipe 24 valve to input compressed air into the fixed mold cavity 40 and the moving mold cavity 50;

[0072] Compressed air pushes the cured sole to separate from the punch core 621 and the cavity 721, reducing demolding resistance;

[0073] The molded shoe sole is removed manually or by a robotic arm, and the surface is inspected for integrity, absence of bubbles or delamination defects.

[0074] Clean the mold surface of any residual material to prepare for the next production run;

[0075] During operation, the entire independent shoe sole forming machine 2 features a dual material distribution device 8 that supports single-sided and double-sided material feeding, adapting to special shoe sole requirements such as two-tone uppers and lowers and sandwich panels. The mold fixing / moving drainage mechanism prevents cooling water retention, ensures mold dryness, and improves shoe sole forming quality and efficiency. The cooling spray component 10, steam distribution pipe 25, and air distribution pipe 24 enhance heating uniformity and demolding efficiency, reducing the defect rate. The automated design of the hydraulic station 3, hydraulic cylinder 22, and water-blocking drive mechanism 9 simplifies manual intervention and improves production efficiency.
