Description

Technical Field

[0001] This utility model relates to the field of shoe sole forming machines, and particularly to a drainage structure for a mold transfer module of 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 utility model patent with publication number CN209718441U discloses a mold-closing device for a vertical popcorn shoe sole forming machine, including a fixed mold fixing frame, a moving mold fixing frame, a hydraulic cylinder fixing seat, a support frame, guide columns, and a hydraulic cylinder. The upper end of the support frame is provided with a support seat, which is fixed to the support frame with screws. The hydraulic cylinder fixing seat is installed on the upper end of the support seat, and a guide column is installed at each of the four corners of the hydraulic cylinder fixing seat. The guide columns are vertically arranged. The fixed mold fixing frame is installed on the upper end of the guide columns. The hydraulic cylinder is installed on the hydraulic cylinder fixing seat, and the telescopic part of the hydraulic cylinder is connected to the moving mold fixing frame. The hydraulic cylinder pushes the moving mold fixing frame to move up and down on the guide columns. The moving mold is installed on the upper surface of the moving mold fixing frame, and the fixed mold is installed on the lower surface of the fixed mold fixing frame. By adopting an up-and-down mold-closing method, the moving mold fixing frame and the moving mold do not exert excessive pressure on the guide columns during up-and-down movement, improving the accuracy of mold closing and extending the service life of the equipment. 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 to 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 to discharge cooling water, which makes it easy for water to accumulate outside the mold, affecting the subsequent sole heating and molding effect. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a drainage structure for the mold transfer module of a vertical shoe sole forming machine, which addresses the shortcomings of the prior art. The structure includes a mold transfer module, mold transfer mounting bases arranged in the same row, a mold transfer water inlet, and a low-displacement mold drainage hole. The bottom plate of the mold transfer frame has water passage holes to guide cooling water into the lower mold transfer drainage chamber, which is then discharged through the drainage hole at the bottom of the drainage chamber. The module integrates a steam inlet, an air inlet, and an exhaust valve to optimize the process. The drainage hole is connected to the drainage valve and the exhaust valve through a three-way pipe to achieve phased control of water and air, avoid water accumulation, and improve cooling uniformity and production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drainage structure for a mold transfer module of a vertical shoe sole forming machine, comprising a mold transfer module and several mold transfer mounting seats for installing mold transfer molds. The mold transfer module is provided with a mold transfer inlet and a mold transfer drain hole. The mold transfer module has a mold transfer cavity inside. The mold transfer module is provided with a mold transfer frame base plate corresponding to the mold transfer mounting seat. The mold transfer inlet is located on the mold transfer frame base plate and communicates with the mold transfer cavity. The mold transfer drain 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 drain hole.

[0007] By adopting the above technical solution, a mold-moving cavity is set in the mold-moving module to accommodate the mold-moving mold mounting base and the mold-moving mold. The mold-moving water inlet is set on the bottom plate of the mold-moving frame and communicates with the mold-moving cavity, serving as an input channel for cooling water. 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 water inlet. At the same time, the bottom plate of the mold-moving frame is inclined towards the direction of the mold-moving drain hole. The cooling water in the mold-moving cavity naturally flows along the inclined bottom plate of the mold-moving frame to the lower mold-moving drain hole during the flow process. Through the inclined design of the bottom plate of the mold-moving frame and the low-position layout of the mold-moving drain hole, a gravity-guided path for cooling water is formed, avoiding disorderly flow or stagnation of cooling water in the mold-moving cavity. The communication structure between the mold-moving water inlet and the mold-moving cavity ensures that cooling water can directly enter the mold area that needs to be cooled. This solves the problem that the original simple drain hole could not effectively guide the water flow, causing cooling water to accumulate outside the mold and thus affecting the subsequent heating and molding effect. It ensures the dryness of the mold surface during the heating stage and improves the molding quality and production stability of the shoe sole.

[0008] The aforementioned drainage structure of the mold transfer module of a vertical shoe sole forming machine can be further configured as follows: a mold transfer cover plate is provided at the location of the mold transfer module 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 bottom plate of the mold transfer frame, and the bottom plate of the mold transfer frame is inclined toward the direction of the mold transfer drainage cavity.

[0009] By adopting the above technical solution, a mold transfer cover plate is set at the mold transfer drainage hole corresponding to the mold transfer module, which cooperates with the mold transfer module to form a mold transfer drainage cavity located below the bottom plate of the mold transfer frame. The mold transfer drainage hole is set at the bottom of the drainage cavity. At the same time, the bottom plate of the mold transfer frame is inclined towards the mold transfer drainage cavity. With the guiding effect of the inclined bottom plate, the cooling water in the mold transfer cavity flows naturally along the inclined surface into the lower mold transfer drainage cavity, and is discharged through the mold transfer drainage hole at the bottom of the drainage cavity. The mold transfer drainage hole is set at the bottom of the drainage cavity, and the cooling water is completely discharged by gravity, avoiding water accumulation in the drainage cavity.

[0010] The aforementioned drainage structure of the mold transfer module of a vertical shoe sole forming machine can be further configured as follows: the bottom plate of the mold transfer frame is placed above the mold transfer drainage cavity, and the bottom plate of the mold transfer frame 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.

[0011] Using the above technical solution, the mold transfer frame base plate, as the bottom covering structure of the mold transfer cavity, is located directly above the mold transfer drainage cavity. By opening several mold transfer water passage holes in the mold transfer frame base plate at positions corresponding to the mold transfer drainage cavity, a conductive path is established between the mold transfer cavity and the mold transfer drainage cavity. This allows cooling water in the mold transfer cavity to flow downwards into the mold transfer drainage cavity through these water passage holes. The placement of the mold transfer water passage holes guides the cooling water in the mold transfer cavity into the mold transfer drainage cavity from multiple dispersed points, avoiding problems such as excessive local water pressure or untimely drainage caused by a single drainage outlet. The mold transfer frame base plate covers the mold transfer drainage cavity. The upper structure serves as both the supporting foundation for the mold transfer cavity and a precise guide for cooling water into the drainage cavity through the water inlet, preventing cooling water from overflowing directly to the outside of the equipment. Combined with the inclined design of the mold transfer frame base plate towards the mold transfer drainage cavity, cooling water can naturally converge along the inclined surface to the water inlet and flow into the drainage cavity, and finally be discharged through the mold transfer drainage hole. This effectively solves the problem of traditional shoe sole forming machines using simple drainage holes that cannot effectively guide water flow, resulting in cooling water accumulation outside the mold. It ensures the dryness of the mold surface during the heating stage, improves the reliability of the drainage system and the quality of shoe sole forming.

[0012] The drainage structure of the mold transfer module of the above-mentioned vertical shoe sole forming machine can be further configured as follows: the mold transfer module is connected to a mold transfer steam inlet and a mold transfer air inlet that are connected to the mold transfer cavity, and the mold transfer module is connected to a mold transfer exhaust valve that is connected to the mold transfer cavity.

[0013] The above technical solution connects the mold transfer steam inlet, mold transfer air inlet, and mold transfer exhaust valve to the mold transfer cavity, forming a gas flow path. The mold transfer steam inlet is used to input steam into the mold transfer cavity to provide the heat energy required for heating. The mold transfer air inlet is used to input compressed air into the mold transfer cavity to assist in demolding. The mold transfer exhaust valve is used to discharge the original air or waste gas in the mold transfer cavity, ensuring that steam or air can effectively fill the cavity. When heating is required, the mold transfer exhaust valve first discharges the air in the mold transfer cavity to prevent air from blocking the contact between steam and the mold or raw materials, allowing the steam to fully act on the TPU particles and other raw materials in the mold, ensuring uniform heating, and specifically solving the problem of insufficient heating affecting the molding effect in traditional equipment. When demolding is required, compressed air is introduced through the mold transfer air inlet to push the sole apart from the mold, improving demolding efficiency. The mold transfer exhaust valve can also discharge excess gas during steam input, maintaining stable pressure in the cavity and preventing excessive air pressure from affecting equipment operation. Combined with the improvement of the drainage structure, the molding quality and production efficiency of the sole are further improved.

[0014] The aforementioned drainage structure of the mold transfer module of a vertical shoe sole forming machine can be further configured as follows: a mold transfer tee pipe is connected to the mold transfer drainage hole, one end of the mold transfer tee pipe is connected to the mold transfer drainage hole, one end is connected to the mold transfer exhaust valve, and the other end is connected to the mold transfer drainage valve.

[0015] By adopting the above technical solution, a mold-moving tee pipe is connected to the mold-moving drain hole, connecting the mold-moving drain hole, the mold-moving vent valve, and the mold-moving drain valve to form an integrated media flow node. The mold-moving drain hole serves as the main channel for cooling water discharge, while the tee pipe connects the mold-moving vent valve and the mold-moving drain valve respectively. The valves' on / off states selectively guide the flow paths of different media. The mold-moving tee pipe integrates drainage and venting functions into the same pipeline node, avoiding the pipeline redundancy and space occupation problems caused by the independent drainage and venting paths in traditional equipment. Through the coordinated control of the mold-moving drain valve and the mold-moving vent valve, the vent valve can be closed and the drain valve opened when drainage is needed, allowing cooling water to flow through… The T-connector drains through the mold-moving drainage hole. When venting is required, the drainage valve is closed and the venting valve is opened, allowing the gas in the mold-moving cavity to be discharged through the T-connector and the mold-moving venting valve. This achieves staged and functional control of different media (water and gas) through the same pipeline interface, avoiding problems such as poor drainage or water entrainment caused by water and gas mixing during discharge. At the same time, the connection structure of the T-connector simplifies the pipeline layout of the system, reduces the complexity of equipment assembly, and improves the controllability of drainage and venting operations and the reliability of system operation. It specifically solves the problems of pipeline complexity, inconvenient operation, and media interference caused by the independent setting of drainage and venting paths in traditional shoe sole forming machines, further optimizing the stability of the production process.

[0016] The aforementioned drainage structure of the mold-moving module of a vertical shoe sole forming machine can be further configured such that: a main drain pipe is provided on one side of the mold-moving module, and the mold-moving drain valve is connected to the main drain pipe via a flexible hose.

[0017] Using the above technical solution, a main drain pipe is set on one side of the mold-moving module as the main drainage route of the system. The mold-moving drain valve is connected to the main drain pipe through a flexible hose, forming a complete drainage path of "mold-moving drain hole → mold-moving tee → mold-moving drain valve → hose → main drain pipe". Through the flexible connection of the hose, the drainage branches of a single mold-moving module and a fixed mold module are connected to the main drain pipe to realize the centralized discharge of cooling water.

[0018] The drainage structure of the moving mold module of the above-mentioned vertical shoe sole forming machine can be further configured as follows: the moving mold includes a moving mold mounting plate, a moving mold base plate and a moving mold connecting column, the moving mold water inlet is opened on the moving mold base plate, the two ends of the moving mold connecting column are respectively connected to the moving mold mounting plate and the moving mold base plate, the moving mold mounting plate is provided with a moving mold shoe core on the surface away from the moving mold base plate, and a cooling spray assembly is installed on the end of the moving mold base plate facing the moving mold mounting plate.

[0019] The above technical solution provides a cooling structure for the punch. The basic structure of the moving mold is formed by the moving mold mounting plate, the moving mold base plate, and the moving mold connecting pillars. The two ends of the moving mold connecting pillars are connected to the moving mold mounting plate and the moving mold base plate, respectively, forming a rigid support frame. The moving mold water inlet is opened on the moving mold base plate, providing a cooling water input channel for the cooling spray assembly. The cooling spray assembly is installed on the end of the moving mold base plate facing the moving mold mounting plate, and can directly spray cooling water onto the moving mold core on the surface of the moving mold mounting plate. This allows the cooling water to be sprayed onto the surface of the moving mold core or the inside of the mold cavity at close range and with high coverage, shortening the path of the cooling water from input to action on the target area, reducing heat transfer loss, and improving cooling efficiency. The moving mold mounting plate, base plate, and connecting pillars have clear division of labor, avoiding the component redundancy and space waste caused by the functional dispersion of traditional molds, and optimizing the structural compactness and functional integration of the mold.

[0020] The aforementioned drainage structure of the moving mold module of a vertical shoe sole forming machine can be further configured as follows: the cooling spray assembly includes a water pipe connector, multiple rows of longitudinal water pipes and horizontal drainage pipes, the water pipe connector passes through the moving mold inlet and connects to the longitudinal water pipes or the horizontal drainage pipes, the longitudinal water pipes and the horizontal drainage pipes are interconnected, and a nozzle is provided at one end facing the moving mold mounting plate.

[0021] Using the above technical solution, the cooling spray assembly consists of a water pipe connector, multiple rows of longitudinal water pipes, and horizontal drain pipes. The water pipe connector passes through the mold inlet and connects to either the longitudinal or horizontal drain pipes, forming a cooling water input channel. The longitudinal and horizontal drain pipes are interconnected, forming a mesh or array-like cooling water distribution network. Nozzles are installed at the end facing the mold mounting plate, allowing cooling water to enter through the water pipe connector and then dispersed to the nozzles via the interconnected paths of the longitudinal and horizontal drain pipes. Finally, the water is sprayed from the nozzles onto the surface of the mold core or the mold cavity. The interconnected longitudinal and horizontal drain pipes create a wider coverage cooling water system. Compared to a single-path spray structure, the network design delivers cooling water more evenly to each nozzle, reducing cooling blind spots. The nozzles are positioned at the end of the longitudinal water pipes and transverse drain pipes facing the mold mounting plate, allowing cooling water to be sprayed directly and accurately onto the surface of the mold core or inside the mold cavity. This avoids cooling delays or coverage deviations caused by nozzle position offsets. The interconnected design of the longitudinal and transverse drain pipes enables the distribution and convergence of cooling water in the pipeline. The distribution density of the water pipes can be adjusted according to the shape of the mold cavity or cooling requirements, enhancing the adaptability of the cooling spray assembly to different mold core structures and further optimizing the controllability and uniformity of the cooling effect.

[0022] The drainage structure of the moving mold module of the above-mentioned vertical shoe sole forming machine can be further configured as follows: the moving mold includes a moving mold support, a moving mold base and a moving mold connecting plate, the moving mold base is provided with a moving mold cavity, the moving mold support is provided with a moving mold feeding gun connected to the moving mold cavity, and the moving mold water inlet is provided on the moving mold support.

[0023] The above technical solution provides a cooling structure for the die cavity. The die cavity is formed by a die cavity support, a die cavity base, and a die cavity connecting plate. The die cavity base serves as a mold cavity or material receiving space. The die cavity support is connected to the die cavity to form a material conveying channel (such as TPU granules for shoe sole molding). The die cavity support is provided with a die cavity in which the die feed gun is connected to form a material conveying channel (such as TPU granules for shoe sole molding). The die cavity water inlet is provided on the die cavity support as an interface for cooling water input, providing a water input path for the cooling system. The die cavity feed gun passes through the die cavity support and connects to the die cavity to ensure that the feed gun outlet is precisely aligned with the cavity, avoiding uneven distribution or overflow of material due to positional deviation during the feeding process, and improving the accuracy of material filling.

[0024] The drainage structure of the mold transfer module of the above-mentioned vertical shoe sole forming machine can be further configured as follows: there are multiple mold transfer mounting seats on the mold transfer module, and the multiple mold transfer mounting seats are arranged in the same row on the mold transfer module. A cooling water main is provided on one side of the mold transfer module, and multiple cooling water pipes are provided on the cooling water main. The cooling water pipes are respectively connected to the mold transfer water inlet.

[0025] Using the above technical solution, the mold-moving module provides a basic carrier for the batch installation of multiple mold-moving dies by setting up multiple mold-moving die mounting seats distributed in the same row. The cooling water main pipe set on one side of the mold-moving module serves as the main input channel for cooling water. Multiple cooling water branches distributed on it are connected to the corresponding mold-moving die inlets of each mold-moving die mounting seat, realizing synchronous cooling water supply to multiple mold-moving dies. The multiple mold-moving die mounting seats are arranged in the same row, so that the mold-moving dies are arranged linearly on the module, which facilitates unified installation, debugging and maintenance, and makes it convenient for workers to bend over and put in inserts. The cooling water main pipe is connected to each mold-moving die inlet through multiple cooling water branches. Compared with the structure of a single main pipe and a single branch pipe, it can supply water to multiple mold-moving dies independently and synchronously, avoiding the problem of insufficient water pressure or uneven cooling caused by multiple dies sharing the same branch pipe, and ensuring the stability and consistency of cooling water input for each mold-moving die.

[0037] like Figures 1-10 As shown, a drainage structure for a transfer mold module of a vertical shoe sole forming machine includes a transfer mold module 1 and three transfer mold mounting seats 3 arranged in a row for mounting transfer molds 2.

When feeding material, the mold transfer exhaust valve 61 vents the air in the mold transfer cavity 10 so that the subsequent steam can contact the TPU particles more fully and ensure uniform heating. When demolding is required, the mold transfer air inlet 14 introduces compressed air into the mold transfer cavity 10 to assist the separation of the shoe sole from the mold.

[0039] Example 1: As Figure 4 , Figure 9As shown, the transfer mold 2 in this embodiment 1 includes a transfer mold mounting plate 21, a transfer mold base plate 22, and a transfer mold connecting column 23. The transfer mold inlet 11 is opened on the transfer mold base plate 22.

The surface of the transfer mold mounting plate 21 away from the transfer mold base plate 22 is provided with a transfer mold core 24. A cooling spray assembly is installed on the end of the transfer mold base plate 22 facing the transfer mold mounting plate 21. The cooling spray assembly includes a water pipe connector 7, multiple rows of longitudinal water pipes 71, and horizontal drain pipes 7. The water pipe connector 7 passes through the transfer mold inlet 11 and connects to the longitudinal water pipes 71. The longitudinal water pipes 71 and the horizontal drain pipes 72 are interconnected and face the transfer mold mounting plate 21. One end is provided with a nozzle 73. In this embodiment 1, when it is necessary to cool down the mold containing the mold core 24 (punch), the cooling water main pipe 8 supplies water to the corresponding water pipe joint 7 through the cooling water pipe 81. Then, the cooling water flows through the water pipe joint 7 into the converging longitudinal water pipes 71 and the transverse drain pipes 72. Then, the cooling water is evenly sprayed on the back of the mold base plate 22 through the nozzle 73 to cool down the molded sole. The cooling water will also enter the mold drainage cavity 50 through the mold water passage hole 41 along the inclined mold frame base plate 4. Then, it will flow into the mold drainage cavity 50 through the mold drainage hole 12 at the bottom of the mold drainage cavity 50 and into the mold tee pipe 6. After passing through the mold drainage valve 62, it will be processed by the main drain pipe 63.
