Description
Technical Field
[0001] This application relates to the technical field of molds, and in particular to a shoe sole forming mold. Background Technology
[0002] Molds are various shapes and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, and stamping. Molds have specific contours or internal cavity shapes, enabling blanks to separate or plastically deform according to predetermined contours, thereby obtaining the desired products.
[0003] In existing technology, shoe soles are injection molded using a mold, which includes a fixed mold and a moving mold. The top wall of the fixed mold has a core, and the bottom wall of the moving mold has a groove. When the moving mold is pressed against the fixed mold, the groove and the core together form a cavity for molding the shoe sole. During injection molding, a heating and melting blank is injected into the cavity using an injection molding machine. After cooling and solidification, a finished product conforming to the shape of the mold cavity is obtained.
[0004] However, in practice, after the blank is shaped in the cavity and lifted off the moving mold, due to the adhesion between the finished shoe sole and the core surface, the operator needs to manually pull the finished shoe sole off the fixed mold core. This operation is cumbersome, time-consuming, and labor-intensive. Therefore, further improvements are needed. Summary of the Invention
[0005] To facilitate the demolding of the finished shoe sole, this application provides a shoe sole molding mold.
[0006] The shoe sole forming mold provided in this application adopts the following technical solution:
[0007] A shoe sole forming mold, characterized in that: it includes a fixed mold (1) and a moving mold (2), wherein the fixed mold (1) has a core (11), and the bottom wall of the moving mold (2) is provided with a groove, and when the moving mold (2) is pressed against the fixed mold (1), the groove and the core (11) together form a cavity (21) for forming the shoe sole; a first lifting seat (12) is slidably installed in the fixed mold (1), the core (11) is installed on the first lifting seat (12), and the fixed mold (1) is provided with a driving component for driving the first lifting seat (12) to move up and down; a lever (3) is installed on one side of the fixed mold (1), the lever ( 3) Used to push out the finished shoe sole from the fixed mold (1); the outer wall of the core (11) is provided with multiple mounting slots (111), and each mounting slot (111) is provided with a push rod (13); a second lifting seat (14) is slidably installed in the fixed mold (1), the lower end of the push rod (13) passes through the first lifting seat (12) and is connected to the second lifting seat (14), and the push rod (13) is slidably installed on the fixed mold (1) through the second lifting seat (14); the fixed mold (1) is provided with a push-back assembly (4), the push-back assembly (4) includes a drive sleeve (41), a drive rod (42) and The guide member has one end of the drive sleeve (41) connected to the first lifting seat (12), one end of the drive rod (42) connected to the second lifting seat (14), and the other end extending into the drive sleeve (41). The drive sleeve (41) and the drive rod (42) are coaxially arranged. The guide member is disposed between the drive sleeve (41) and the drive rod (42) to guide the drive sleeve (41) and the drive rod (42) to slide in opposite directions. A docking seat (15) is provided between the first lifting seat (12) and the second lifting seat (14), and the docking seat (15) is fixedly connected to the fixed mold (1). The guide member includes a guide strip. (43) and push block (44), guide bar (43) is slidably installed on docking seat (15) so that it can slide in the horizontal direction, drive rod (42) is provided with guide groove (421), guide bar (43) passes through guide groove (421); guide bar (43) is inclined, and guide block (431) is provided at the upper end and the lower end of guide bar (43); the number of push block (44) is corresponding to the number of guide block (431), and each push block (44) is provided on the inner peripheral wall of drive sleeve (41) to push the corresponding guide block (431).
[0008] By adopting the above technical solution, the core is set on the first lifting seat. After the blank is shaped in the cavity, it is lifted away from the moving mold. Then, the first lifting seat is driven to move the core downward, so that the finished shoe sole is separated from the core. Then, the finished shoe sole on the fixed mold is pushed outward by the lever, which improves the ease of operation of separating the finished shoe sole from the fixed mold. After molding, the first lifting seat is driven to move downward. Under the action of the push rod, the separation of the finished shoe sole from the core on the first lifting seat is ensured. During the downward movement of the first lifting seat, the push rod is lifted under the action of the push component, so that the finished shoe sole is separated from the core of the first lifting seat. The raised push rod elevates the finished shoe sole, creating space between it and the fixed mold for the push rod to pass through. This facilitates the push rod to pull the finished shoe sole outward from the push rod, improving the overall ease of operation. When the first lifting seat moves downward, it drives the drive sleeve downward. Under the action of the guide, the drive rod rises, thereby raising the push rod on the second lifting seat to elevate the finished shoe sole above the fixed mold, achieving reverse sliding of the first and second lifting seats. When the first lifting seat moves the drive sleeve downward, it pushes the guide block of the guide strip through the push block, causing the guide strip to slide horizontally. The guide strip slides in conjunction with the guide groove of the drive rod, achieving the lifting of the drive rod. That is, when the first lifting seat moves downward, the second lifting seat rises, and when the first lifting seat rises, the second lifting seat moves downward, improving the overall ease of operation.
[0009] Optionally, the push block (44) has a first guide surface (441), and the guide block (431) has a second guide surface (432), with the first guide surface (441) of the push block (44) abutting against the second guide surface (432) of the corresponding guide block (431).
[0010] By adopting the above technical solution, the push block can push the guide bar to slide during the lifting process through the abutting cooperation of the first guide surface and the second guide surface, and the cooperation between the drive sleeve and the drive rod can be improved by utilizing the abutting cooperation of the first guide surface and the second guide surface.
[0011] Optionally, a translation seat (5) is slidably installed on one side of the fixed mold (1), and a rotating shaft (51) is rotatably installed on the translation seat (5); one end of the lever (3) is connected to the rotating shaft (51), and multiple levers (3) are arranged at intervals along the axial direction of the rotating shaft (51), and an interval area (131) is formed between two adjacent push rods (13) for the lever (3) to extend into.
[0012] By adopting the above technical solution, after the shoe sole is formed on the fixed mold, the translation seat is driven to slide between the fixed mold and the moving mold, so that the lever is inserted into the gap area between two adjacent ejector pins. Then, the rotating shaft is driven to rotate, so that the lever can peel the shoe sole from the ejector pin and push the shoe sole outward, thereby improving work efficiency and ease of operation.
[0013] Optionally, the lever (3) is connected to a clamping rod (6) for clamping the finished shoe sole, one end of which is hinged to the outer wall of the lever (3); the lever (3) is provided with a swing assembly (7) for driving the clamping rod (6) to swing.
[0014] By adopting the above technical solution, when the lever peels the finished shoe sole from the top rod, the clamping rod clamps the finished shoe sole, thereby clamping the finished shoe sole between the clamping rod and the lever. At this time, by moving the translation seat outward, the peeled finished shoe sole can be sent out, improving the operational convenience of the overall structure.
[0015] Optionally, the clamping rod (6) is connected to a force-applying plate (61) at one end near the lever (3). The swing assembly (7) includes a force-applying ring (71) and a force-applying rod (72). The force-applying ring (71) is slidably sleeved on the outer wall of the lever (3). The force-applying ring (71) has a through groove (711) for the force-applying plate (61) to pass through. One end of the force-applying rod (72) is connected to the force-applying ring (71), and the other end is connected to a guide post (721). The side wall of the shift seat (5) is provided with a guide groove (52) for the guide post (721) to be inserted. When the length direction of the lever (3) is horizontal, the guide groove (52) forces the free end of the clamping rod (6) to swing away from the lever (3). When the length direction of the lever (3) is not horizontal, the guide groove (52) forces the free end of the clamping rod (6) to swing towards the side closer to the lever (3) to clamp the finished shoe sole.
[0016] By adopting the above technical solution, when the finished shoe sole needs to be removed from the ejector pin, the length direction of the control lever is flipped to a horizontal state, with the free end of the lever facing the interval area. Then, the translation seat is driven to slide towards the side closer to the fixed mold, causing the lever to insert into the interval area between two adjacent ejector pins. Next, the rotating shaft is driven to rotate, causing the free end of the lever to flip upwards (non-horizontal state), thus peeling the finished shoe sole off the ejector pin. During the rotation of the rotating shaft, under the action of the guide groove, the force-applying rod drives the force-applying ring to slide, thereby causing the free end of the clamping rod to swing towards the side closer to the lever through the force-applying plate, thus clamping the finished shoe sole. Then, the translation seat is driven to slide away from the fixed mold. When the lever continues to swing to a horizontal state (the free end of the lever is away from the interval area), the clamping rod releases the finished shoe sole, thereby transferring the finished shoe sole out and improving overall work efficiency.
[0017] Optionally, the guide groove (52) includes a first guide arc segment (521) and two second guide arc segments (522). The two second guide arc segments (522) are respectively connected to the two ends of the first guide arc segment (521). The virtual central axis of the first guide arc segment (521) and the second guide arc segment (522) coincides with the central axis of the rotating shaft (51). The distance from the first guide arc segment (521) to the center of the rotating shaft (51) is greater than the distance from the second guide arc segment (522) to the center of the rotating shaft (51).
[0018] By adopting the above technical solution, the virtual diameter changes of the first and second guide arc segments are utilized to control the slippage of the force ring during the rotation of the lever driven by the rotating shaft, thereby controlling the clamping rod to clamp or release the finished shoe sole, thus improving the overall ease of operation.
[0019] In summary, this application includes at least one of the following beneficial technical effects:
[0020] 1. By setting up the reverse thrust component, during the downward movement of the first lifting seat, the push rod is raised under the action of the reverse thrust component, thereby separating the finished shoe sole from the core of the first lifting seat. The raised push rod can elevate the finished shoe sole, creating a space between the finished shoe sole and the fixed mold for the push rod to pass through, thus facilitating the push rod to push the finished shoe sole outward from the push rod, improving the overall operational convenience of the structure;
[0021] 2. By using guide bars, when the first lifting seat moves the drive sleeve downward, the push block pushes the guide block of the guide bar, thereby causing the guide bar to slide horizontally. The guide bar slides in conjunction with the guide groove of the drive rod, realizing the lifting of the drive rod. That is, when the first lifting seat moves downward, the second lifting seat rises, and when the first lifting seat rises, the second lifting seat moves downward, improving the overall ease of operation.
[0022] 3. By using the swing assembly, when the finished shoe sole needs to be removed from the ejector pin, the control lever is flipped horizontally with its free end facing the gap area. The translation seat is then driven to slide closer to the fixed mold, allowing the lever to insert into the gap area between two adjacent ejector pins. Next, the rotating shaft is driven to rotate, causing the free end of the lever to flip upwards (not horizontal), thus peeling the finished shoe sole off the ejector pin. During the rotation of the rotating shaft, the force-applying rod drives the force-applying ring to slide under the action of the guide groove. This, in turn, causes the free end of the clamping rod to swing towards the side closer to the lever, clamping the finished shoe sole. The translation seat is then driven to slide away from the fixed mold. When the lever continues to swing to a horizontal position (with the free end of the lever away from the gap area), the clamping rod releases the finished shoe sole, thus transferring it out and improving overall work efficiency.

[0030] The following combination Figures 1-6 This application will be described in further detail. Example 1
[0031] This application discloses a shoe sole forming mold.
[0032] Reference Figure 1 A shoe sole forming mold includes a fixed mold 1 and a movable mold 2. The movable mold 2 is mounted on top of the fixed mold 1. A guide post 16 is fixedly mounted on the fixed mold 1, and the guide post 16 passes through the movable mold 2. The movable mold 2 is slidably mounted on top of the fixed mold 1 via the guide post 16. In this embodiment, the movable mold 2 is driven to rise and fall by a cylinder.
[0033] Reference Figure 2 , Figure 3A first lifting seat 12 is slidably installed inside the fixed mold 1. A core 11 is fixedly installed on the first lifting seat 12. A groove is opened on the bottom wall of the moving mold 2. When the moving mold 2 is pressed against the fixed mold 1, the groove and the core 11 together form a cavity 21 for molding the shoe sole. An injection head (not shown in the figure) for injecting blank into the cavity 21 is installed on the moving mold 2.
[0034] The fixed mold 1 is equipped with a driving component for driving the first lifting seat 12 to rise and fall. In this embodiment, the driving component includes a driving plate 17 and a driving cylinder. The driving plate 17 is slidably installed inside the fixed mold 1. A fixing rod 171 connects the first lifting seat 12 and the driving plate 17, and the first lifting seat 12 and the driving plate 17 are fixedly connected by the fixing rod 171. The cylinder body of the driving cylinder (not shown in the figure) is fixedly installed on the side wall of the fixed mold 1, and the piston rod of the driving cylinder is fixedly connected to the driving plate 17. When the piston rod of the driving cylinder extends outward, the driving plate 17 rises, and the top wall of the first lifting seat 12 remains flush with the top wall of the fixed mold 1. When the piston rod of the driving cylinder retracts inward, the driving plate 17 moves downward.
[0035] A second lifting seat 14 is slidably installed inside the fixed mold 1. The second lifting seat 14 is located between the first lifting seat 12 and the drive plate 17. The outer wall of the core 11 has multiple mounting slots 111. The multiple mounting slots 111 are arranged at intervals along the length direction of the finished shoe sole. A push rod 13 is slidably installed in each mounting slot 111. The lower end of the push rod 13 passes through the first lifting seat 12 and is fixedly connected to the second lifting seat 14. The push rod 13 is slidably installed on the fixed mold 1 through the second lifting seat 14.
[0036] Reference Figure 3 , Figure 4 The fixed mold 1 is equipped with a push-back assembly 4. When the first lifting seat 12 moves the core 11 downward, the push-back assembly 4 forces the ejector rod 13 to rise, thereby lifting the finished shoe sole away from the upper surface of the fixed mold 1. The push-back assembly 4 includes a drive sleeve 41, a drive rod 42, and a guide. One end of the drive sleeve 41 is fixedly connected to the bottom wall of the first lifting seat 12, and one end of the drive rod 42 is fixedly connected to the top wall of the second lifting seat 14, while the other end extends into the drive sleeve 41. The drive sleeve 41 and the drive rod 42 are coaxially arranged. A return spring 45 is installed between the drive sleeve 41 and the drive rod 42. One end of the return spring 45 is fixedly connected to the inner wall of the drive sleeve 41, and the other end is fixedly connected to the drive rod 42.
[0037] A docking seat 15 is fixedly installed on the inner wall of the fixed mold 1. The docking seat 15 is located between the first lifting seat 12 and the second lifting seat 14. A first docking cylinder 151 and a second docking cylinder 152 are fixedly installed on the docking seat 15. The first docking cylinder 151 and the second docking cylinder 152 are coaxially arranged, with the first docking cylinder 151 located outside the second docking cylinder 152. The first docking cylinder 151 is sleeved on the outer peripheral wall of the drive sleeve 41, and the inner diameter of the first docking cylinder 151 is adapted to the outer diameter of the drive sleeve 41. The second docking cylinder 152 is sleeved on the outer peripheral wall of the drive rod 42, and the inner diameter of the second docking cylinder 152 is adapted to the outer diameter of the drive rod 42.
[0038] A guide member is disposed between the drive sleeve 41 and the drive rod 42 to guide the drive sleeve 41 and the drive rod 42 to slide in opposite directions. The guide member includes a guide bar 43 and a push block 44. The outer wall of the second docking cylinder 152 is provided with a moving groove 153. The guide bar 43 is slidably installed in the moving groove 153 of the second docking cylinder 152 so that it can slide in the horizontal direction. The outer peripheral wall of the drive rod 42 is provided with a guide groove 421. The guide bar 43 passes through the guide groove 421 and is inclined. The upper end and the lower end of the guide bar 43 are both fixedly installed with guide blocks 431.
[0039] The number of pushing blocks 44 corresponds to the number of guide blocks 431. Each pushing block 44 is fixedly installed on the inner peripheral wall of the drive sleeve 41 to push the corresponding guide block 431. The pushing block 44 has a first guide surface 441, and the guide block 431 has a second guide surface 432. The first guide surface 441 of the pushing block 44 abuts against the second guide surface 432 of the corresponding guide block 431. The first guide surfaces 441 of the two pushing blocks 44 are arranged in parallel, and the second guide surfaces 432 of the two guide blocks 431 are arranged in parallel.
[0040] Reference Figure 1 , Figure 5 A mounting bracket 8 is fixedly installed on one side of the fixed mold 1. A translation seat 5 is slidably installed on the mounting bracket 8. In this embodiment, the translation seat 5 can be driven by a linear motor (not shown in the figure) to allow the translation seat 5 to move closer to or away from the fixed mold 1. A rotating shaft 51 is rotatably installed on the translation seat 5. The axial direction of the rotating shaft 51 is consistent with the length direction of the finished shoe sole. Multiple levers 3 are provided on the rotating shaft 51. The multiple levers 3 are arranged at intervals along the axial direction of the rotating shaft 51. One end of each lever 3 is fixedly connected to the outer peripheral wall of the rotating shaft 51. The levers 3 are used to push the finished shoe sole on the fixed mold 1 outward.
[0041] For ease of description, the end of the lever 3 furthest from the rotating shaft 51 is defined as the free end of the lever 3, and the gap between two adjacent push rods 13 is defined as the interval zone 131. Multiple push rods 13 form multiple interval zones 131, which are used to allow the free end of the lever 3 to extend into. In this embodiment, the rotating shaft 51 is driven by a rotary cylinder 53. The cylinder body of the rotary cylinder 53 is fixedly mounted on the translation seat 5, and the rotating end of the rotary cylinder 53 is connected and fixed to the rotating shaft 51. In actual production, a collection frame (not shown in the figure) can be placed on the side of the mounting frame 8 furthest from the fixed mold 1 to receive the finished shoe soles pushed outward by the lever 3.
[0042] The implementation principle of Embodiment 1 of this application is as follows: After the blank is shaped in the cavity 21, it is lifted away from the moving mold 2, driving the first lifting seat 12 to move downward. Under the obstruction of the push rod 13, the finished shoe sole is separated from the core 11. During the downward movement of the first lifting seat 12, with the cooperation of the guide strip 43 and the push block 44, the second lifting seat 14 is driven to rise, thereby driving the push rod 13 to rise upward, so as to lift the finished shoe sole on the push rod 13 away from the upper surface of the fixed mold 1, so as to facilitate the insertion of the lever 3. Then, the free end of the lever 3 is inserted into the interval area 131 of the push rod 13 through the translation seat 5, driving the rotating shaft 51 to rotate, so that the lever 3 can push the finished shoe sole on the push rod 13 outward, improving the ease of operation for separating the finished shoe sole from the fixed mold 1. Example 2
[0043] This application discloses a shoe sole forming mold.
[0044] The difference between the shoe sole molding die disclosed in this application and that in Example 1 is as follows:
[0045] Reference Figure 6 In this embodiment, the lever 3 is equipped with a clamping rod 6 for clamping the finished shoe sole. One end of the clamping rod 6 is hinged to the outer wall of the lever 3. For ease of description, the end of the clamping rod 6 away from the lever 3 is defined as the free end of the clamping rod 6.
[0046] One end of the clamping rod 6 near the lever 3 has an integrally formed force-applying piece 61. The lever 3 is provided with a swing assembly 7 for driving the clamping rod 6 to swing. The swing assembly 7 includes a force-applying ring 71 and a force-applying rod 72. The force-applying ring 71 is slidably sleeved on the outer wall of the lever 3, and the force-applying ring 71 has a through groove 711 for the force-applying piece 61 to pass through. One end of the force-applying rod 72 is fixedly connected to the force-applying ring 71, and the other end is fixedly connected to a guide post 721.
[0047] The side wall of the translation seat 5 is provided with a guide groove 52 for the guide post 721 to be inserted. The guide groove 52 includes a first guide arc segment 521 and two second guide arc segments 522. The two second guide arc segments 522 are respectively connected to the two ends of the first guide arc segment 521. The virtual central axis of the first guide arc segment 521 and the second guide arc segment 522 coincide with the central axis of the rotation shaft 51. The distance from the first guide arc segment 521 to the center of the rotation shaft 51 is greater than the distance from the second guide arc segment 522 to the center of the rotation shaft 51. When the length direction of the lever 3 is horizontal, the guide post 721 moves into the end of the second guide arc segment 522 away from the first guide arc segment 521, and forces the free end of the clamping rod 6 to swing away from the lever 3. When the length direction of the lever 3 is not horizontal, the guide post 721 moves into the first guide arc segment 521, and forces the free end of the clamping rod 6 to swing towards the lever 3 to clamp the finished shoe sole.
[0048] The implementation principle of Embodiment 2 of this application is as follows: When it is necessary to remove the finished shoe sole from the top rod 13, the length direction of the control lever 3 is flipped to a horizontal state, and the free end of the lever 3 faces the interval area 131. Then, the translation seat 5 is driven to slide towards the side closer to the fixed mold 1, so that each lever 3 is inserted into the corresponding interval area 131. Next, the rotating shaft 51 is driven to rotate, so that the free end of the lever 3 is flipped upward (non-horizontal state), so as to peel the finished shoe sole off the top rod 13.
[0049] During the rotation of the rotating shaft 51, the force-applying rod 72 drives the force-applying ring 71 to slide under the action of the guide groove 52. This causes the free end of the clamping rod 6 to swing towards the side closer to the lever 3 via the force-applying plate 61, thereby clamping the finished shoe sole. Then, the translation seat 5 is driven to slide away from the fixed mold 1. When the lever 3 continues to swing to a horizontal state (the free end of the lever 3 is away from the interval area 131), the clamping rod 6 releases the finished shoe sole, thereby transferring the finished shoe sole out and improving overall work efficiency.
[0050] By utilizing the virtual diameter changes of the first guide arc segment 521 and the second guide arc segment 522, the sliding of the force ring 71 is controlled during the rotation of the lever 3 driven by the rotating shaft 51, thereby controlling the clamping rod 6 to clamp or release the finished shoe sole, thus improving the overall ease of operation.
[0051] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
