Description

Technical Field

[0001] This utility model relates to the field of shoe sole forming machine, and particularly to a vertical shoe sole forming machine. 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. Since the molded sole needs to be cooled after mold closing, cooling water pipes need to be connected at both the fixed mold and the moving mold to cool the molded sole in order to ensure cooling efficiency. However, this sole molding 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 heating and molding effect of the sole.

[0005] 2. 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

[0006] The technical problem to be solved by this utility model is to provide a vertical shoe sole forming machine to address the shortcomings of the prior art. This forming machine adopts a vertical frame structure. The fixed mold module has multiple sets of shoe sole punches arranged in a single row along the vertical direction, and the moving mold module is correspondingly configured with a single row of shoe sole concave molds. The punches and concave molds achieve precise mold closing through a vertical guide mechanism. The single-row mold layout allows the operating station to be extended in the horizontal direction, and workers can complete the placement and removal of inserts from the side, reducing the intensity of bending over. The vertical structure makes the mold force direction consistent with gravity, avoiding the cantilever bending deformation caused by the horizontal arrangement of molds in horizontal equipment, and extending the service life of the mold. The equipment integrates a material distribution device with return material circulation and a differentiated cooling system. The side spray component of the concave mold and the water storage chamber of the punch work together, and with the linkage control of exhaust and drainage, it improves the convenience of operation and the stability of the mold, while achieving the technical effects of improving the utilization rate of raw materials and shortening the forming cycle. It can also realize multiple feeding methods and efficient drainage structure, and is suitable for the efficient mass production of complex shoe sole structures.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a vertical shoe sole forming machine, comprising a frame, a fixed mold module and a moving mold module axially correspondingly arranged 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, and a cooling water distribution pipe. Both the fixed mold module and the moving mold module are provided with several corresponding fixed mold mounting seats and moving mold mounting seats. Each fixed mold mounting seat and moving mold mounting seat is equipped with a corresponding shoe sole punch and shoe sole die. After the shoe sole punch and shoe sole die are closed, they cooperate to form a shoe sole forming cavity for forming the shoe sole. The frame... Two material distribution devices are provided on the side. The material distribution devices are respectively connected to the shoe sole punch and / or shoe sole die and communicate with the shoe sole forming cavity. 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.

[0008] Using the above technical solution, by setting axially corresponding fixed mold modules and moving mold modules on the frame, and using hydraulic cylinders to drive the moving mold modules to achieve mold closing and opening, after mold closing, the shoe sole punch and shoe sole die form the shoe sole forming cavity. Simultaneously, two material distribution devices on one side of the frame are connected to the shoe sole punch and / or shoe sole die respectively and communicate with the shoe sole forming cavity to achieve material supply. The fixed mold cavity and moving mold cavity inside the fixed mold module and moving mold module are respectively supplied with air, steam, and cooling water through air distribution pipes, steam distribution pipes, and cooling water distribution pipes. The cooling water is discharged in conjunction with the fixed mold drainage mechanism and the moving mold drainage mechanism. The shoe sole punch or shoe sole die can be arbitrarily installed on the fixed mold module or moving mold module, requiring only… The axial alignment of the punch and die is sufficient. This technical solution, by setting up two material distribution devices, can be connected to the shoe sole punch and / or shoe sole die respectively, realizing arbitrary material feeding in the vertical direction on one side or double-sided material feeding. It meets the diverse material feeding needs of shoe soles with special structures such as single-color shoe soles, carbon fiber shoe soles, double-sided feeding, two-color shoe soles, shoe soles with interlayers or requiring carbon fiber, etc. It solves the problem of poor adaptability of a single material cylinder. At the same time, the fixed mold module and the moving mold module are respectively equipped with a fixed mold drainage mechanism and a moving mold drainage mechanism, which can drain the cooling water in the fixed mold cavity and the moving mold cavity in time. This avoids the problem of water accumulation on the outside of the mold caused by using only simple drainage holes and drainage pipes in the existing technology, and ensures the subsequent shoe sole heating and forming effect.

[0009] The aforementioned vertical shoe sole forming machine 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 on the mold mounting base in cooperation with the shoe sole punch or shoe sole die, 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.

[0010] The above technical solution involves setting a mold inlet on the shoe sole punch or die, allowing cooling water to be introduced into the mold cavity via a cooling water distribution pipe. Simultaneously, a mold water storage cavity is formed on the mold mounting base, cooperating with the shoe sole punch or die. A mold drain hole and a lower drainage gap, communicating with the outside of the mold module, are provided at the mold mounting base. A mold drain drive assembly controls the sealing or opening of the mold drain hole by driving a mold drain pin. In this structure, the mold water storage cavity is located at the lower part of the mold cavity, efficiently collecting cooling water and draining the mold. The water hole connects the solid mold water storage cavity and the lower drain gap. When the solid mold drainage drive component drives the solid mold drainage pin to open the solid mold drainage hole, the cooling water in the water storage cavity can be directly discharged from the solid mold module through the lower drain gap, avoiding the stagnation of cooling water in the solid mold cavity. In the non-drainage stage, the drainage hole can be blocked by the pin to prevent steam or air leakage during heating or pressure holding. Through this controllable drainage structure design, the problem of water accumulation outside the mold is effectively solved, ensuring that the inside of the solid mold module is dry, thereby avoiding the impact of water accumulation on the subsequent shoe sole heating and molding effect.

[0011] The aforementioned vertical shoe sole forming machine 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, a plurality of overflow drainage holes are opened on the overflow baffle to connect 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.

[0012] Using the above technical solution, a mold retaining plate is installed above the mold drain hole of the mold module, dividing the mold cavity into a mold water storage chamber and a mold overflow chamber. An overflow baffle is installed on the side of the mold retaining plate to form an overflow drain chamber. An overflow drain hole is opened on the overflow baffle above the mold retaining plate. A mold drain cylinder is used as a driving component, and its linked mold drain pin passes through the overflow baffle to control the opening and closing of the mold drain hole. The mold retaining plate ensures that cooling water is preferentially collected in the lower mold water storage chamber. Under normal conditions, most of the cooling water can be discharged by driving the pin of the mold drain cylinder to open the mold drain hole. When the cooling water exceeds the mold... When the sink plate is at its maximum height, excess cooling water enters the mold overflow cavity and flows into the overflow drain cavity through the overflow drain hole, then drains through the overflow drain pipe, forming a dual drainage mechanism of "main drainage + overflow". This avoids the risk of excessive cooling water overflowing to the outside. At the same time, the mold drainage cylinder is installed outside the mold assembly, which is convenient for maintenance and avoids occupying internal space. The design of the mold drainage pin passing through the overflow baffle ensures the coaxiality of the pin and the drain hole, improves the sealing performance, and prevents steam leakage during the heating stage. Through the combination of sink plate separation, graded drainage and sealing control, the problem of water accumulation in the mold is effectively solved, ensuring a dry environment inside the mold assembly and ensuring stable subsequent heating and molding effects.

[0013] The aforementioned vertical shoe sole forming machine can be further configured as follows: a water baffle plate and a water baffle driving mechanism for driving the water baffle plate to move closer to or away from the fixed mold module are provided on one 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 the cavity is provided with a water baffle plate drainage hole. A main drainage pipe is provided on one side of the fixed mold module. The water baffle plate drainage hole and the overflow drainage pipe are both connected to the main drainage pipe.

[0014] By adopting the above technical solution, a water baffle and a water-blocking drive mechanism are installed on the side of the frame corresponding to the fixed mold module. This allows the water baffle to remain below the lower drainage gap. The concave cavity on the side of the water baffle facing the fixed mold module receives the cooling water discharged from the lower drainage gap and flows into the main drainage pipe through the drainage holes in the water baffle within the cavity. At the same time, the overflow drainage pipe is also connected to the main drainage pipe for centralized drainage. During the drainage stage, the water baffle moves to directly below the lower drainage gap via the water-blocking drive mechanism. Its concave structure can effectively receive the cooling water discharged from the fixed mold drainage holes through the lower drainage gap, preventing the cooling water from dripping directly onto the frame or ground during the drainage process. To prevent water from spreading due to surface accumulation, the drainage holes of the baffle plate and the overflow drainage pipe are connected to the main drainage pipe, so that both regular drainage and overflow drainage from the fixed mold side are discharged through a unified channel, realizing integrated management of drainage paths and preventing pipeline chaos and water residue caused by multi-path drainage. In addition, the water-blocking drive mechanism can drive the baffle plate away from the fixed mold module during non-drainage stages to avoid interference with mold closing, mold opening and other processes. Through the design of active acceptance, centralized flow guidance and process avoidance, the problem of water accumulation outside the mold is further solved, ensuring that the surrounding environment of the equipment is dry, reducing the risk of equipment corrosion caused by water accumulation, and ensuring the stability of subsequent heating and molding processes.

[0015] The aforementioned vertical shoe sole forming machine can be further configured such that: 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 provided on the mold transfer module and a mold transfer frame base plate provided at the corresponding mold transfer mounting seat of the mold transfer module; the mold transfer inlet is provided on the mold transfer frame base plate and connects to the mold transfer cavity; the mold transfer drainage hole is provided 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; and the mold transfer drainage hole is connected to the main drainage pipe.

[0016] Using the above technical solution, a mold-moving water inlet is provided on the shoe sole punch or shoe sole die, allowing the cooling water distribution pipe to be connected to the mold-moving cavity to introduce cooling water. Simultaneously, a mold-moving frame base plate is provided at the corresponding mold-moving mounting seat of the mold-moving module, with the mold-moving water inlet located on the base plate and connected to the mold-moving cavity. A mold-moving drain hole with a cross-sectional height lower than the mold-moving water inlet is provided on one side of the mold-moving module, and the mold-moving frame base plate is inclined towards the drain hole, connecting the drain hole to the main drain pipe. The inclined design of the mold-moving frame base plate utilizes gravity to direct the cooling water entering the mold-moving cavity towards the drain hole. Because the cross-sectional height of the mold transfer drain hole is lower than that of the mold transfer inlet, a natural drainage gradient can be formed, ensuring that cooling water can be discharged through the mold transfer drain hole without the need for additional drive components. At the same time, the mold transfer drain hole is connected to the main drain pipe to achieve centralized treatment of drainage from the fixed mold side, avoiding the dispersion of pipelines and water accumulation caused by separate drainage of the mold transfer module. Through the combination of inclined flow guidance, low-level drainage and centralized pipeline, the problem of cooling water retention in the mold transfer cavity is effectively solved, ensuring that the inside of the mold transfer module is dry and preventing water accumulation from affecting the heating and molding effect of the shoe sole. At the same time, the simplified drainage structure reduces the difficulty of maintenance.

[0017] The aforementioned vertical shoe sole forming machine can be further configured as follows: the mold transfer module is provided with a mold transfer cover plate corresponding to the mold transfer drainage hole, the mold transfer cover plate and the mold transfer module cooperate to form a mold transfer drainage cavity, the mold transfer drainage hole is located at the bottom of the mold transfer drainage cavity, the mold transfer drainage cavity is located below the mold transfer frame bottom plate, the mold transfer frame bottom plate is covered above the mold transfer drainage cavity, and the mold transfer frame bottom plate is provided with a plurality of mold transfer water passage holes corresponding to the mold transfer drainage cavity to connect the mold transfer cavity and the mold transfer drainage cavity.

[0018] By adopting the above technical solution, a mold-moving cover plate is installed at the corresponding mold-moving drainage hole of the mold-moving module, which cooperates with the mold-moving module to form a mold-moving drainage cavity. The mold-moving drainage hole is set at the bottom of the mold-moving drainage cavity. At the same time, several mold-moving water passage holes are opened on the mold-moving frame bottom plate covering the mold-moving drainage cavity. The cooling water in the mold-moving cavity flows into the mold-moving drainage cavity through the water passage holes and then discharges through the mold-moving drainage hole. The inclined design of the mold-moving frame bottom plate and the combination of the mold-moving water passage holes can guide the cooling water in the mold-moving cavity to the mold-moving drainage cavity by gravity. The closed drainage space formed by the mold-moving cover plate avoids drainage. During the process, cooling water overflows, and the drainage holes at the bottom of the mold-moving drainage cavity are connected to the main drainage pipe through a centralized pipeline, achieving integrated management with the drainage system on the fixed mold side. The distribution design of the water passages ensures that the cooling water in each area of ​​the mold-moving cavity can efficiently flow into the drainage cavity. The synergistic effect of the inclined bottom plate and the closed drainage cavity improves the drainage speed and thoroughness, avoiding water accumulation inside the mold-moving module. Through the structural optimization of graded flow guidance, closed water collection and centralized discharge, the dry environment of the mold-moving module is further guaranteed, ensuring a uniform and stable temperature field during the shoe sole molding process and improving product quality consistency.

[0019] The aforementioned vertical shoe sole forming machine can be further configured as follows: the mold moving module is connected to a mold moving vent valve communicating with the mold moving cavity; the mold fixed module is connected to a mold fixed vent valve communicating with the mold fixed cavity; a mold moving tee pipe is connected to the mold moving drainage hole; one end of the mold moving tee pipe is communicating with the mold moving drainage hole, one end is connected to the mold moving vent 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.

[0020] The above technical solution involves installing mold-moving vent valves and fixed-mold vent valves on the mold-moving module and fixed-mold module, respectively, which are connected to their respective cavities. A mold-moving tee is connected to the mold-moving drain hole, with one end connected to the drain hole, the other end connected to the mold-moving vent valve, and the third end connected to the mold-moving drain valve. The mold-moving drain valve is then connected to the main drain pipe via a flexible hose. The mold-moving and fixed-mold vent valves can directly discharge steam or residual air generated by heating from the mold-moving and fixed-mold cavities, preventing excessively high air pressure within the cavities from hindering cooling water circulation or causing abnormal pressure. This ensures that cooling water can smoothly fill the cavities and evenly remove heat. The structural design of the mold-moving tee integrates the drain hole, vent valve, and drain valve, allowing venting and drainage functions to be controlled through the same pipeline node. When drainage is required, open the mold transfer drain valve. Under the influence of gravity and air pressure difference, the cooling water in the cavity enters the tee pipe through the mold transfer drain hole. At the same time, the mold transfer vent valve continuously discharges residual gas to prevent air blockage and incomplete drainage. After drainage is completed, closing the mold transfer drain valve can prevent impurities or air in the main drain pipe from flowing back into the mold transfer cavity. The hose connection method adapts to the displacement requirements of the mold transfer module during mold closing and opening, avoiding damage to the pipeline by pulling. Through the integrated control of venting and drainage, the problem of gas retention affecting cooling efficiency is solved. Furthermore, the reliability and adaptability of the drainage system are improved through valve control and hose connection, ensuring that there is no water residue in the mold cavity, reducing the risk of equipment corrosion, ensuring the stability of the temperature field during shoe sole molding, and thus improving the consistency of product quality.

[0021] The aforementioned vertical shoe sole forming machine can be further configured as follows: 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, the shoe sole punches are all installed in the fixed mold mounting base, the shoe sole dies are all 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 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 die includes a die support, a die base and a die connecting plate, the die base is provided with a die cavity, the die support has a moving mold inlet that connects a cooling water distribution pipe to the moving mold cavity, and a cooling spray assembly is installed at one end of the die support facing the die base.

[0022] By adopting the above technical solution, the feeding gun is placed on at least one of the shoe sole punch and shoe sole die and connected to the material distribution device and the shoe sole forming cavity. An embodiment is proposed in which the shoe sole punch is installed on a fixed mold mounting base and the shoe sole die is installed on a moving mold mounting base. The direct connection between the feeding gun, the material distribution device, and the shoe sole forming cavity ensures that the raw material can be accurately and efficiently injected into the forming cavity, avoiding pressure loss or material solidification caused by an excessively long feeding path. The design of installing the punch and die on the fixed mold and moving mold mounting bases respectively makes the mold opening and closing action more stable in coordination with the feeding and cooling systems. The fixed mold water inlet introduces cooling water into the fixed mold water storage cavity formed by the punch base and the fixed mold mounting base, allowing the cooling water to be evenly distributed. The punch core achieves large-area cooling, while the mold inlet on the die holder, combined with the cooling spray assembly, directly provides directional spray cooling to the die cavity. These two cooling structures are optimized for different heated areas of the punch and die, respectively. The fixed mold water storage chamber achieves overall immersion cooling, while the spray assembly provides localized enhanced cooling, synergistically improving the accuracy of mold temperature control. Simultaneously, the modular punch and die structure design facilitates the replacement of punch cores and die cavities for different shoe sole models, reducing mold replacement costs. The combination of precise material feeding and differentiated cooling methods effectively solves product defects caused by uneven material filling and temperature distribution differences during the molding process, improving the consistency and production efficiency of shoe sole molding.

[0023] The aforementioned vertical shoe sole forming machine can be further configured such that: the cooling spray assembly includes a water pipe connector connected to a cooling water distribution pipe, multiple rows of longitudinal water pipes and transverse drainage pipes, the water pipe connector passing through the mold inlet and connecting to the longitudinal water pipes or the transverse drainage pipes, the longitudinal water pipes and the transverse drainage pipes being interconnected, and a nozzle being provided at one end facing the die connecting plate.

[0024] By adopting the above technical solution, the cooling spray assembly is configured to include a water pipe connector connected to the cooling water distribution pipe, multiple rows of longitudinal water pipes and horizontal drainage pipes. The direct connection between the water pipe connector and the cooling water distribution pipe ensures a stable supply of cooling water. The cross-conduction design of the multiple rows of longitudinal water pipes and horizontal drainage pipes forms a grid-like water flow distribution structure, allowing the cooling water to be evenly distributed within the pipes, avoiding uneven spraying caused by excessively high or low local water pressure. The nozzles facing the die connecting plate can directionally spray the cooling water onto the surface and surrounding area of ​​the die cavity. The spraying method increases the heat exchange area between the cooling water and the mold, while the water flow impact accelerates heat transfer. Compared to traditional immersion cooling, this method can more quickly remove the heat released from the mold cavity due to the solidification of the raw material. The multi-row nozzle layout ensures that all areas of the mold cavity receive continuous and uniform cooling, avoiding uneven shrinkage or surface defects in the shoe sole due to excessively high local temperatures. The interconnection between the horizontal drainage pipes and the vertical water pipes allows for partial cooling through other pipes even when one pipe is blocked, improving system reliability. Through the synergistic effect of grid-based water flow distribution and directional spraying, the problems of low cooling efficiency and large temperature distribution differences on the mold side are effectively solved, shortening the shoe sole molding cycle and improving the dimensional accuracy and surface quality consistency of the product.

[0025] The aforementioned vertical shoe sole forming machine can be further configured as follows: the material distribution device includes a material distribution tank, a material return component, and a material distribution air outlet. The material distribution tank includes a tank body, a material inlet pipe disposed above the tank body, and several material outlet joints disposed at the lower end of the tank body. The material return component includes a material return chamber and a material return pipe. One end of the material return pipe is connected to the tank body, and the other end is connected to the material return chamber. A material return three-way valve is provided at the bottom of the material return chamber. One end of the material return three-way valve is connected to the material distribution air outlet, one end is connected to the material return chamber, and one end is connected to the tank body.

[0026] Using the above technical solution, the material distribution device is configured to include a material distribution tank, a return material assembly, and a feed distribution air vent. The material distribution tank includes a tank body, a material inlet pipe above the tank body, and several discharge connectors at the bottom. The return material assembly includes a return chamber and a return pipe. One end of the return pipe is connected to the tank body, and the other end is connected to the return chamber. A three-way valve is installed at the bottom of the return chamber. One end of the three-way valve is connected to the feed distribution air vent, one end is connected to the return chamber, and the other end is connected to the tank body. The material inlet pipe transports the raw materials to the tank body. The several discharge connectors enable multi-channel synchronous feeding, ensuring uniform and efficient material distribution. The return pipe... Residual materials not discharged in time are guided back to the return chamber to prevent them from settling and solidifying at the bottom of the tank. The feed three-way valve switches between states to achieve coordinated control of return material recovery and active feeding. The feed distribution air vent can optimize the material conveying speed and pressure through air pressure regulation to prevent uneven filling caused by pressure fluctuations during feeding. Through the multi-joint distribution of the distribution tank, the recycling of the return material component, and the intelligent switching of the three-way valve, the problems of low raw material utilization and poor feeding stability of traditional distribution devices are effectively solved, improving the accuracy of material distribution and the continuity of system operation, and reducing production costs.

Both the fixed mold module 2 and the moving mold module 3 have several corresponding fixed mold mounting seats 21 and moving mold mounting seats 31. Each fixed mold mounting seat 21 and moving mold mounting seat 31 is equipped with a corresponding shoe sole punch 4 and a shoe sole concave mold 5. After the shoe sole punch 4 and the shoe sole concave mold 5 are closed, they cooperate to form a shoe sole forming cavity 40 for forming the shoe sole. Mold assembly 2 and mold transfer assembly 3 have a fixed mold cavity 20 and a mold transfer cavity 30 inside. Air distribution pipe 12 is used to supply air to the fixed mold cavity 20 and the mold transfer cavity 30. Steam distribution pipe 13 is used to supply steam to the fixed mold cavity 20 and the mold transfer cavity 30. Cooling water distribution pipe 14 is used to supply cooling water to the fixed mold cavity 20 and the mold transfer cavity 30. The fixed mold assembly 2 is provided with a fixed mold drainage mechanism to discharge the cooling water in the fixed mold cavity 20. The mold transfer assembly 3 is provided with a mold transfer drainage mechanism to discharge the cooling water in the mold transfer cavity 30. The main drain pipe 15 collects and discharges the cooling water discharged from the fixed mold drainage mechanism and the mold transfer drainage mechanism.

[0047] like Figures 1-4 As shown, two vertically arranged material distribution devices 6 are provided on one side of the frame 1. The material distribution devices 6 are used to connect the shoe sole punch and / or shoe sole die and communicate with the shoe sole forming cavity 40. The material distribution device 6 includes a material distribution tank, a material return assembly, and a material distribution air outlet 63. The material distribution tank includes a tank body 61, a material inlet pipe 611 located above the tank body 61, and several material outlet joints 612 located at the lower end of the tank body 61. The material return assembly includes a material return chamber 62 and a material return pipe 621. One end of the material return pipe 621 is connected to the tank body 61, and the other end is connected to the material return chamber 621. One end is connected to the return material chamber 62. The bottom of the return material chamber 62 is equipped with a three-way inlet valve 622. One end of the three-way inlet valve 622 is connected to the inlet distribution air vent 63, one end is connected to the return material chamber 62, and the other end is connected to the tank body 61. Two material distribution devices 6 are used to supply material to the molds in the fixed mold module 2 and the moving mold module 3 respectively, enabling single-sided and double-sided material feeding for the molds in the fixed mold module 2 and the moving mold module 3. The shoe sole punch 4 and shoe sole die 5 can be selectively installed on the fixed mold module 2 and the moving mold module 3, such as... Figure 9As shown, three mold installation methods are given. For example, when it is necessary to mold a shoe sole with two colors on the top and bottom or to place inserts (carbon sheets, spring sheets, etc.), the shoe sole punch 4 and shoe sole die 5 on the fixed mold assembly 2 and the moving mold assembly 3 are both equipped with feeding guns 50.

[0050] like Figures 1-18 As shown, the vertical shoe sole forming machine of this utility model has the following steps when in use:

[0051] Preparation phase:

[0052] According to the type of shoe sole to be formed (such as two colors on the top and bottom, with interlayer, etc.), select the appropriate shoe sole punch 4 and shoe sole die 5, and install them in the fixed mold mounting base 21 of the fixed mold module 2 and the moving mold mounting base 31 of the moving mold module 3, respectively.

[0053] Check the alignment of the sole punch 4 and sole die 5 to ensure that a complete sole forming cavity 40 is formed after the mold is closed; if it is a double-sided material supply sole (such as upper and lower two colors), a material supply gun 50 needs to be installed on both the sole punch 4 and sole die 5, and connected to the discharge connector 612 of the two material distribution devices 6 respectively.

[0054] Check the valve status of air distribution pipe 12, steam distribution pipe 13, and cooling water distribution pipe 14 to ensure that the mold moving drain valve 36 and the mold fixing drain cylinder 22 are in the initial closed state.

[0055] II. Mold Closure and Injection Stage

[0056] Mold closing operation:

[0057] Start the hydraulic cylinder 11 to drive the moving mold module 3 to move along the guide post towards the fixed mold module 2 until the shoe sole punch 4 and the shoe sole concave mold 5 are completely closed to form a sealed shoe sole forming cavity 40.

[0058] Select the material supply mode according to the sole specifications, taking "two-tone soles" as an example:

[0059] The material distribution device 6 is activated: the upper material distribution device 6 injects light-colored foamed granules into the material distribution tank 61 through the material feed pipe 611, and the lower material distribution device 6 injects dark-colored foamed granules.

[0060] Open the feed three-way valve 622 to connect the feed tank 61 and the feed distribution air outlet 63. The material is injected into the top of the cavity of the shoe sole punch 4 and the bottom of the cavity of the shoe sole die 5 through the discharge connector 612 and the feed gun 50 respectively.

[0061] After the material feeding is completed, close the feed three-way valve 622, start the return material assembly 62, and recover the excess material;

[0062] III. Steam Heating Stage:

[0063] Open the mold venting valve 26 and the mold moving venting valve 34 to expel the original air in the cavity, ensuring that the steam fully contacts the material, so that the foamed particles expand and fill the shoe sole molding cavity 40.

[0064] Open the valve of steam distribution pipe 13 to input high-temperature steam into the fixed mold cavity 20 and the moving mold cavity 30;

[0065] After heating for the set time, close the valve on steam distribution pipe 13 to stop heating;

[0066] IV. Cooling and Drainage Stage

[0067] Open the valve of the cooling water distribution pipe 14, and the cooling water flows into the fixed mold cavity 20 and the moving mold cavity 30 through the fixed mold inlet 201 and the moving mold inlet 301 respectively;

[0068] When the cooling spray assembly 8 on the mold moving side is activated, cooling water enters the longitudinal water pipe 82 and the transverse drain pipe 83 through the water pipe joint 81, and is evenly sprayed onto the surface of the concave mold cavity 521 or the surface of the convex mold core 421 through the nozzle 84 to accelerate the cooling and solidification of the shoe sole; the cooling water in the mold cavity 20 flows into the lower mold water storage cavity 202 along the mold sink plate 23.

[0069] After cooling is completed, the hydraulic cylinder 11 is started to drive the mold moving module 3 to move away from the fixed mold module 2 along the guide post. The water blocking drive mechanism drives the water blocking plate 7 to stop below the lower drain gap 205. The fixed mold drain cylinder 22 is started to drive the fixed mold drain pin 221 to exit the fixed mold drain hole 204. The cooling water flows into the cavity of the water blocking plate 7 through the fixed mold drain hole 204 and the lower drain gap 205, and then flows into the main drain pipe 15 through the water blocking plate drain hole 73.

[0070] If the water level in the mold cavity 20 exceeds the height of the mold base plate 23, the excess cooling water flows into the overflow drain cavity 241 through the overflow drain hole 242 and then into the main drain pipe 15 through the overflow drain pipe 25.

[0071] The cooling water in the mold transfer cavity 30 flows along the inclined mold transfer frame bottom plate 32 and flows into the mold transfer drainage cavity 331 below through the mold transfer water passage 321;

[0072] After the cooling water is collected in the mold transfer drainage chamber 331, it flows into the main drainage pipe 15 through the mold transfer drainage hole 302, the mold transfer tee pipe 35, and the mold transfer drainage valve 36.

[0073] During drainage, the mold moving drain valve 36 and the mold moving vent valve 34 remain closed;

[0074] V. Demolding Stage

[0075] The water-blocking drive mechanism moves the water-blocking plate 7 away from the fixed mold module 2 to avoid affecting the next mold closing;

[0076] The mold drainage cylinder 22 drives the mold drainage pin 221 to reset, blocking the mold drainage hole 204.

[0077] Open the air distribution pipe 12 valve to input compressed air into the fixed mold cavity 20 and the moving mold cavity 30;

[0078] Compressed air pushes the cured sole to separate from the punch core 421 and the cavity 521, reducing demolding resistance;

[0079] 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.

[0080] Clean the mold surface of any residual material to prepare for the next production run;

[0081] Throughout the process, the dual material distribution device 6 enables it to support 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 molding quality and efficiency. The cooling spray component 8, steam distribution pipe 13, and air distribution pipe 12 enhance heating uniformity and demolding efficiency, reducing the defect rate. The automated design of hydraulic cylinder 11 and water-blocking drive mechanism simplifies manual intervention and improves production efficiency.
