Description

Technical Field

[0001] This utility model relates to the field of shoe sole forming machines, and particularly to a drainage structure for a fixed mold 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 fixed mold module of a vertical shoe sole forming machine, which addresses the shortcomings of the prior art. The fixed mold in this drainage structure can be selected as a concave mold or a convex mold as needed. The overall structure significantly improves cooling efficiency and drainage reliability, and solves the problems of mold water accumulation and low heating efficiency caused by poor drainage in traditional equipment, thus ensuring the quality of shoe sole forming and production stability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drainage structure for a fixed mold module of a vertical shoe sole forming machine, wherein the fixed mold module is provided with a water inlet, and includes a fixed mold module and a plurality of fixed mold mounting seats for mounting the fixed mold. The fixed mold mounting seats are provided with fixed mold drainage holes that communicate with the outside of the fixed mold module. The fixed mold module is provided with a fixed mold drainage drive component corresponding to the fixed mold drainage hole. The output end of the fixed mold drainage drive component is connected to a fixed mold drainage pin, which drives the fixed mold drainage pin to enter or disengage from the fixed mold drainage hole.

[0007] By adopting the above technical solution, a mold drainage hole connected to the outside of the mold module is set on the mold mounting base as a drainage channel, and a mold drainage drive component is set at the corresponding position of the mold module. The mold drainage pin is driven to move to enter or disengage from the mold drainage hole, thereby realizing active opening and closing control of the drainage hole. During the steam heating stage of shoe sole molding, the mold drainage drive component drives the mold drainage pin to enter and block the mold drainage hole, preventing steam leakage through the drainage hole, ensuring stable steam pressure and temperature in the mold cavity, and improving heating efficiency. After cooling, the mold drainage drive component drives the mold drainage pin to disengage and open the mold drainage hole, allowing the cooling water inside the mold module to be discharged directly to the outside through the hole, preventing cooling water from accumulating inside or outside the mold. At the same time, during the demolding stage, the mold drainage drive component drives the mold drainage pin to enter and block the mold drainage hole, preventing a large amount of air leakage, stabilizing demolding, and solving the problem of water accumulation caused by the inability to actively control traditional simple drainage holes. This ensures that the mold surface is dry during subsequent heating and molding, and avoids water accumulation affecting the heating effect.

[0008] The drainage structure of the fixed mold module of the above-mentioned vertical shoe sole forming machine can be further configured as follows: the fixed mold module has a fixed mold cavity inside to accommodate the fixed mold mounting seat, the fixed mold mounting seat and the fixed mold cooperate to form a fixed mold water storage cavity, the fixed mold water storage cavity is located at the lower part of the fixed mold cavity, and the fixed mold drainage holes are all connected to the fixed mold water storage cavity, the bottom of the fixed mold mounting seat has a lower drainage gap, the fixed mold drainage holes are respectively connected to the lower drainage gap and the fixed mold water storage cavity, and the fixed mold drainage holes are blocked or opened by the fixed mold drainage pin.

[0009] Using the above technical solution, the mold cavity inside the mold assembly provides installation space for the mold mounting base. The mold mounting base and the mold form a mold water storage cavity at the bottom of the mold cavity through cooperation. The cooling water generated during the cooling process naturally collects in the mold water storage cavity at the bottom using gravity. The mold drain hole serves as a channel connecting the mold water storage cavity and the bottom drain gap of the mold mounting base. The movement of the mold drain pin can actively block or open this channel. During the steam heating stage, the mold drain pin blocks the mold drain hole to prevent steam from leaking through the drain hole and ensure stable steam pressure and temperature in the mold cavity. After cooling is completed, the mold drain pin opens the mold drain hole, and the cooling water collected in the mold water storage cavity flows into the bottom drain gap through the mold drain hole and is discharged to the outside of the mold assembly. This avoids the accumulation of cooling water inside or outside the mold and solves the problem of mold water accumulation caused by the inability to actively control the traditional drain hole and the disorderly flow of cooling water. This ensures that the mold surface is dry during subsequent heating and molding and avoids water accumulation affecting the heating effect.

[0010] The drainage structure of the fixed mold module of the above-mentioned vertical shoe sole forming machine can be further configured as follows: a fixed mold sink plate is provided above the fixed mold drainage hole of the fixed mold module, the fixed mold sink plate divides the fixed mold cavity into the fixed mold water storage cavity and the fixed mold overflow cavity, an overflow baffle is provided on the side of the fixed mold sink plate corresponding to the fixed mold module, an overflow drainage cavity exists between the overflow baffle and the fixed mold module, an overflow drainage pipe is connected in the overflow drainage cavity, and a plurality of overflow drainage holes are opened on the overflow baffle to conduct the fixed mold overflow cavity and the overflow drainage cavity, the overflow drainage holes are located above the fixed mold sink plate.

[0011] Using the above technical solution, a mold retaining plate is installed above the mold drain hole in the mold module. The height difference between the retaining plate and the plate divides the mold cavity into a lower mold water storage cavity and a higher mold overflow cavity. An overflow baffle is installed on the side of the retaining plate, forming an overflow drainage cavity between it and the mold module. An overflow drainage hole is opened on the overflow baffle above the retaining plate, connecting the mold overflow cavity and the overflow drainage cavity. An overflow drainage pipe is connected within the overflow drainage cavity as an overflow outlet. When the cooling water volume in the mold water storage cavity exceeds [a certain value] during the cooling process... When the capacity is reached, excess cooling water will automatically flow over the mold base plate due to gravity, enter the high-level mold overflow cavity, and then flow into the overflow drain cavity through the overflow drain hole, and finally be discharged through the overflow drain pipe. This layered drainage structure avoids the problem of the mold water storage cavity not being able to be discharged in time through the mold drain hole due to excessive cooling water discharge at one time, and overflowing to the outside of the mold. Combined with the precise control of the conventional cooling water volume by the mold drain hole, the drainage reliability is further improved, ensuring that the mold surface remains dry during the heating stage and avoiding water accumulation that affects the heating and molding effect of the shoe sole.

[0012] The above-mentioned drainage structure of the fixed mold module of the vertical shoe sole forming machine can be further configured as follows: the fixed mold drainage drive component is a fixed mold drainage cylinder, the fixed mold drainage cylinder is installed on the outside of the fixed mold module and is linked with a fixed mold drainage pin, the fixed mold drainage pin passes through the overflow baffle and enters or leaves the fixed mold drainage hole.

[0013] The above technical solution uses a fixed mold drainage cylinder as the fixed mold drainage drive component. Utilizing the telescopic power characteristics of the cylinder, and through a structural design that installs it outside the fixed mold module (avoiding direct contact with high-temperature steam or cooling water inside the mold cavity, reducing the risk of component corrosion or thermal deformation), the fixed mold drainage pin is linked and controlled. Under the drive of the cylinder, the pin passes through the overflow baffle and is guided to enter or leave the fixed mold drainage hole, thereby realizing active opening and closing control of the drainage hole.

[0014] The drainage structure of the fixed mold module of the above-mentioned vertical shoe sole forming machine can be further configured as follows: the fixed mold includes a fixed mold support, a fixed mold base and a fixed mold connecting plate, a fixed mold shoe mold is provided on the fixed mold base, a fixed mold feeding gun connected to the fixed mold shoe mold is passed through the fixed mold support, the water inlet is provided on the fixed mold support, and the fixed mold base and the fixed mold mounting seat cooperate to form the fixed mold water storage cavity.

[0015] Using the above technical solution, the fixed mold support serves as the basic load-bearing structure, providing installation support for the fixed mold feeding gun and introducing cooling water through its inlet for efficient cooling of the fixed mold shoe mold. The fixed mold base, as the component that directly supports the fixed mold shoe mold, cooperates with the fixed mold mounting seat to form a fixed mold water storage cavity. The inlet is designed to provide a stable water source for cooling. Combined with the low-position collection design of the fixed mold water storage cavity, the cooling water can quickly cover the surface of the shoe mold and be discharged in a concentrated manner, shortening the cooling time. The cooperation structure between the fixed mold base and the mounting seat precisely defines the position and volume of the fixed mold water storage cavity. Combined with the previously mentioned design of the fixed mold drainage cylinder controlling the opening and closing of the drainage hole, it avoids cooling water residue or overflow inside the mold, ensuring that the mold surface is dry during the heating stage and preventing water accumulation from affecting the heating and molding quality of the shoe sole.

[0016] The drainage structure of the fixed mold module of the above-mentioned vertical shoe sole forming machine can be further configured as follows: there are multiple fixed mold mounting seats and fixed mold drainage drive components on the fixed mold module, and the fixed mold mounting seats and fixed mold drainage drive components are arranged correspondingly. Multiple fixed mold mounting seats are arranged in the same row on the fixed mold module, and the fixed mold module is connected to a fixed mold exhaust valve that communicates with the fixed mold cavity.

[0017] By adopting the above technical solution, the setting of multiple fixed mold mounting seats and corresponding fixed mold drainage drive components enables each fixed mold mounting seat to control the opening and closing of its drainage holes through an independent drive component, thereby selectively controlling the molding process of one or more shoe soles. The layout of the same row simplifies the routing of pipes / lines, reduces system complexity, and facilitates workers to install and unload parts, avoiding the difficulty for workers to insert parts in multiple rows of excessively wide fixed mold modules.

[0018] The drainage structure of the fixed mold module of the above-mentioned vertical shoe sole forming machine can be further configured as follows: it also includes a water baffle plate disposed on one side of the fixed mold module and a water baffle driving mechanism for driving the water baffle plate to approach or move away from the fixed mold module. The water baffle driving mechanism can drive the water baffle plate to stay below the lower gap.

[0019] By adopting the above technical solution, a baffle plate is set on one side of the fixed mold module, and the baffle plate is controlled to move closer to or away from the fixed mold module by a water-blocking drive mechanism. The drive mechanism can drive the baffle plate to stop precisely below the lower gap. During the drainage process, it can form a physical barrier and guide effect on the cooling water discharged from the drainage hole of the fixed mold to the lower gap, preventing the cooling water from flowing directly into the moving module below due to gravity or flow rate. This specifically solves the problem of water accumulation outside the mold caused by the lack of drainage path control in traditional equipment.

[0020] The above-mentioned drainage structure of the fixed mold module of the vertical shoe sole forming machine can be further configured as follows: the water blocking drive mechanism includes a water blocking bracket, a rodless cylinder mounted on the water blocking bracket, and a linear slide rail connected to the water blocking bracket and the water blocking plate, wherein the water blocking plate is connected to a sliding block on the rodless cylinder.

[0021] Using the above technical solution, the water-blocking drive mechanism uses a water-blocking bracket as the basic load-bearing structure, on which a rodless cylinder and a linear slide rail are installed. The water-blocking plate is connected to the sliding block of the rodless cylinder, thereby driving the sliding block to move along the cylinder axis through the rodless cylinder. This causes the water-blocking plate to move closer to or away from the fixed mold module under the guidance of the linear slide rail, and to stop precisely below the lower gap, thus achieving precise control of the cooling water discharge path.

[0022] The drainage structure of the fixed mold module of the above-mentioned vertical shoe sole forming machine can be further configured as follows: the side of the baffle plate facing the fixed mold module has a cavity, and the cavity is provided with a drainage hole for the baffle plate.

[0023] By adopting the above technical solution, a concave cavity is set on the side of the baffle plate facing the fixed mold module, and the drainage holes of the baffle plate are arranged in the concave cavity. The concave structure of the cavity forms a concentrated collection area for cooling water, avoiding splashing. The collected cooling water is discharged in an orderly manner through the drainage holes, avoiding the overflow problem caused by the accumulation of cooling water in the concave cavity. At the same time, the structure of the concave cavity increases the contact area between the baffle plate and the cooling water, improving the guiding efficiency of water flow. Combined with the position design of the drainage holes, the collection-discharge path of cooling water is further optimized, ensuring the cleanliness of equipment operation and the stability of the drainage system.

[0024] The drainage structure of the fixed mold module of the above-mentioned vertical shoe sole forming machine can be further configured as follows: a main drainage pipe is provided on one side of the fixed mold module, and the drainage hole of the baffle plate is connected to the main drainage pipe through a flexible hose.

[0025] By adopting the above technical solution, a main drain pipe is set on one side of the fixed mold module as a centralized discharge channel for cooling water. The drain holes on the baffle plate are connected to the main drain pipe through a flexible hose. The flexible hose is used to achieve a movable drainage path connection. Because the hose is flexible, when the baffle plate is moved by the baffle drive mechanism, the hose can adaptively adjust its shape with the movement of the baffle plate, avoiding pipe pulling, breakage or detachment caused by rigid connection, thus ensuring the reliability of drainage connection. At the same time, the cooling water collected by the baffle plate is introduced into the main drain pipe through its drain holes and the hose, realizing the orderly collection and centralized discharge of cooling water. This avoids the irregular splashing or accumulation of cooling water outside the equipment. It specifically solves the problems of inflexible drainage path and cooling water overflow caused by fixed connection method and scattered pipeline layout in traditional drainage systems, improving the cleanliness of equipment operation and the stability of drainage system.

[0036] like Figures 1-9 As shown, a drainage structure for a fixed mold module of a vertical shoe sole forming machine includes a fixed mold module 1 and three fixed mold mounting seats 3 arranged in a row for mounting a fixed mold 2. Each fixed mold mounting seat 3 has a fixed mold drainage hole 31 that connects its inner cavity to the outer cavity of the fixed mold module 1. Each fixed mold module 1 is equipped with a fixed mold drainage cylinder 4 corresponding to one of the fixed mold drainage holes 31. The output end of each fixed mold drainage cylinder 4 is connected to a fixed mold drainage pin 41. The fixed mold 2 includes a fixed mold support 21, a fixed mold base 22, and a fixed mold connecting plate 23. A fixed mold shoe mold 221 is mounted on the fixed mold base 22, and a fixed mold connecting plate 23 is mounted on the fixed mold support 21. The fixed mold shoe mold 221 is connected to the fixed mold feeding gun 222. The fixed mold support is provided with a water inlet 211. The fixed mold module 1 has a fixed mold cavity V that accommodates the fixed mold mounting base 3. The fixed mold base 22 and the fixed mold mounting base 3 cooperate to form a fixed mold water storage cavity V1. The fixed mold water storage cavity V1 is located at the lower part of the fixed mold cavity V, and the fixed mold drainage holes 31 are all connected to the corresponding fixed mold water storage cavity V1. The bottom of the fixed mold mounting base 3 has a lower gap 30. The fixed mold drainage holes 31 are connected to the lower gap 30 and the fixed mold water storage cavity V1 respectively. The fixed mold drainage cylinder 4 drives the fixed mold drainage pin 41 to block or open the fixed mold drainage hole 31.

[0037] like Figures 3-9 As shown, a mold base plate 5 is provided above the mold drain hole 31 in the mold module 2. The mold base plate 5 divides the mold cavity V into a mold water storage cavity V1 and a mold overflow cavity V2. An overflow baffle 6 is provided on the side of the mold base plate 5 in the mold module 2. An overflow drain cavity V3 exists between the overflow baffle 6 and the mold module 2. An overflow drain pipe 7 is connected inside the overflow drain cavity V3. Several overflow drain holes 61 are opened on the overflow baffle 6 to connect the mold overflow cavity V2 and the overflow drain cavity V3. The overflow drain holes 61 are located above the mold base plate 5. The mold drain cylinder 4 is installed outside the mold module 1 and is linked to the mold drain pin 41. The mold drain pin 41 passes through the overflow baffle 6 and enters or exits the mold drain hole 31. The mold module 1 is connected to a mold exhaust valve 8 that is connected to the mold cavity V.

[0038] like Figures 1-2 As shown, a baffle plate 9 and a water-blocking drive mechanism are provided on one side of the fixed mold module 1. The water-blocking drive mechanism can drive the baffle plate 9 to stay below the lower gap 30 to receive the cooling water discharged from the fixed mold module 1. The water-blocking drive mechanism includes a water-blocking bracket 91, a rodless cylinder 92 set on the water-blocking bracket 91, and a linear slide rail 93 connected to the water-blocking bracket 91 and the water-blocking plate 9. The water-blocking plate 9 is connected to a sliding block 921 on the rodless cylinder 92. The side of the water-blocking plate 9 facing the fixed mold module 1 has a cavity, and a water-blocking plate drain hole 90 is provided in the cavity. A main drain pipe 11 is provided on one side of the fixed mold module 1, and the water-blocking plate drain hole 90 is connected to the main drain pipe 11 through a hose.

[0039] like Figures 1-9 As shown, when the fixed mold module drainage structure of this utility model is used in a vertical shoe sole molding machine, the vertical shoe sole molding machine has a frame, a fixed mold module 1 and a moving mold module 12 arranged axially on the frame, and a hydraulic cylinder that drives the moving mold module to move closer to or away from the fixed mold module 1. A main drain pipe 11, a cooling water pipe 12, an air pipe 13, and a steam pipe 14 are provided on one side of the frame. The air pipe 13 and the steam pipe 14 are respectively connected to both sides of the fixed mold module 1 to supply air and steam to the fixed mold cavity V of the fixed mold module 1. The fixed mold exhaust valve 8 is connected to the fixed mold cavity V to exhaust the air in the fixed mold cavity V when the fixed mold 221 is fed in, so that the subsequent steam can more fully contact the TPU particles, ensuring uniform heating. When the vertical shoe sole molding machine is in use, the worker installs the fixed mold 2 onto the fixed mold mounting base 3 of the fixed mold module 1. The fixed mold base of the fixed mold 2... The base 22 cooperates with the fixed mold mounting base 3 to form a fixed mold water storage cavity V1. The water inlet 211 on the fixed mold support 21 is connected to the cooling water pipe 12 on the side of the frame through a hose. The fixed mold feeding gun 222 is connected to the external TPU particle supply equipment. If there are shoe sole inserts (such as carbon sheets or wear-resistant sole sheets), the worker can conveniently put the inserts into the fixed mold shoe mold 221 (concave or convex mold) on the side of the frame. Then, the hydraulic cylinder drives the mold moving module 12 to approach the fixed mold module 1 to close the mold, gradually closing the mold to form three sealed molding cavities. The fixed mold exhaust valve 8 opens simultaneously to discharge the air in the fixed mold cavity V. The fixed mold feeding gun 222 injects TPU foam particles into the molding cavity. The steam pipe 14 introduces high-temperature steam into the fixed mold cavity V to soften and bond the TPU foam particles in the molding cavity. At the same time, the fixed mold drainage pin 41 is inserted into the fixed mold drainage hole 31 under the drive of the fixed mold drainage cylinder 4. Figure 6(State), seal the mold drain hole to prevent steam leakage and ensure heating efficiency. After steam heating is completed, the cooling water pipe 12 introduces cooling water into the mold 2 through the inlet 211 of the mold support 21 to cool the molded sole. The cooling water accumulates in the mold water storage cavity V1 between the mold base 22 and the mold mounting base 3. Some of the cooling water overflows into the mold overflow cavity V2 due to excess. The cooling water overflowing into the mold overflow cavity V2 enters the overflow drainage cavity V3 through the overflow drain hole 61 on the overflow baffle 6 and is finally discharged through the overflow drain pipe 7. The hydraulic cylinder drives the mold moving module 12 away from the mold module 1 to open the mold. The water blocking drive mechanism drives the water blocking plate 9 to slide along the linear slide rail 93 to below the lower gap 30 ( Figure 2 (State), the mold drain cylinder 4 drives the mold drain pin 41 to exit the mold drain hole 31, opening the drainage channel. Cooling water in the mold water storage chamber V1 flows into the lower drain gap 30 at the bottom of the mold mounting base 3 through the mold drain hole 31. Its concave cavity receives the cooling water discharged from the lower drain gap 30 and guides it into the main drain pipe 11 through the baffle plate drain hole 90 and hose in the concave cavity, preventing cooling water from splashing to the outside of the equipment and causing water accumulation. Then, the baffle drive mechanism drives the baffle plate 9 to reset along the linear slide rail 93. The mold drain pin 41 is inserted into the mold drain hole 31 under the drive of the mold drain cylinder 4. The air pipe 13 introduces compressed air into the mold cavity V, assisting the separation of the shoe sole from the mold shoe mold 221, so that the mold overflow cavity V2 is in Air blowing demolding prevents excessive air leakage and ensures stable demolding. The mold vent valve 8 reopens to balance the pressure inside and outside the mold cavity, preventing the sole from sticking to the mold due to negative pressure. The worker removes the molded sole, completing the first molding process. Through the linkage control of the mold drainage cylinder 4 and the mold drainage pin 41, precise drainage of the mold water storage chamber V1 is achieved. The overflow baffle 6 and the overflow drain pipe 7 work together to handle overflow water, preventing excessive accumulation of cooling water. The water baffle 9 and the main drain pipe 11 work together to prevent external water accumulation, ensuring equipment cleanliness. The overall structure significantly improves cooling efficiency and drainage reliability, solving problems such as mold water accumulation and low heating efficiency caused by poor drainage in traditional equipment, ensuring the quality of sole molding and production stability.
