Description

Technical Field

[0001] This utility model relates to the field of shoe sole production equipment, specifically a vulcanizing machine for producing rubber shoe soles. Background Technology

[0002] The mold used in the vulcanizing machine for silicone shoe sole production is a tool used to inject liquid silicone into the mold and maintain the shape and size of the shoe sole during the vulcanization process. The mold is usually made of metal or silicone material and has the desired shoe sole shape and details.

[0003] Chinese patent CN221365440U discloses a vulcanizing machine for producing rubber shoe soles, including a box body. A partition is fixedly connected to the lower side of the box body. A first fixed plate is fixedly connected to the upper surface of the partition. A second cylinder is fixedly connected to the middle of the upper surface of the first fixed plate. The end of the second cylinder away from the first fixed plate vertically penetrates a lower pressure plate. A template is set inside the lower pressure plate. The template is slidably connected to the lower pressure plate. The second cylinder is fixedly connected to the template. Second fixed posts are fixedly connected to the four corners of the lower surface of the lower pressure plate.

[0004] Regarding the aforementioned technologies, in existing vulcanizing machines used for producing rubber shoe soles, after the templates are separated, the soles inside the templates are ejected. However, the ejected soles are still located between the upper and lower templates, requiring manual removal. In summary, existing vulcanizing machines for producing rubber shoe soles do not easily allow for the automatic removal of the produced soles. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a vulcanizing machine for producing rubber shoe soles, so as to solve the technical problem that existing vulcanizing machines for producing rubber shoe soles are not easy to automatically remove the produced soles.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vulcanizing machine for producing rubber shoe soles, comprising a base, on which two fixed lower molds are fixedly connected, and a movable lower mold is slidably disposed between the two fixed lower molds in a vertical direction. An upper mold is connected to the base via multiple second telescopic columns. When the movable lower mold is not lowered, it can combine with the two fixed lower molds and cooperate with the upper mold. When the movable lower mold is lowered, the shoe sole will detach from the movable lower mold and remain inside the fixed lower mold. The machine also includes a mounting frame, which is fixedly connected to one side of one of the fixed lower molds. A clamping mechanism for clamping the shoe sole is rotatably connected to the mounting frame.

[0007] By adopting the above technical solution, a rotating clamping mechanism is set on one side of the lower mold. After the upper mold and the lower mold are separated, the movable lower mold located in the middle position is lowered, and the clamping mechanism moves to clamp the shoe sole between the shoe soles, which automatically realizes the shoe sole removal work. This is beneficial for shoe sole demolding and greatly reduces the labor intensity of workers.

[0008] The present invention is further configured such that a rotating shaft is rotatably connected to the top of the mounting bracket, a rotating rod is fixedly connected to the rotating shaft in the radial direction, a connecting plate is fixedly connected to the end of the rotating rod away from the rotating shaft, a fixed plate is fixedly connected to the connecting plate through a guide rod, a sliding plate is slidably connected between the fixed plate and the connecting plate, and a first telescopic column for controlling the sliding of the sliding plate is installed on the connecting plate facing the direction of the sliding plate.

[0009] Preferably, the two soles are held together by a fixed plate and a sliding plate.

[0010] The present invention is further configured such that when the sliding plate and the connecting plate are in contact with each other, the distance between the fixed plate and the sliding plate is greater than the thickness of the shoe sole.

[0011] Preferably, this avoids situations where the shoe sole is too thick to hold the shoe securely.

[0012] The present invention is further configured such that the width of both the fixed plate and the sliding plate is greater than the distance between the soles of the two fixed lower molds.

[0013] Preferably, the fixing plate and the sliding plate are able to clamp the edge of the shoe sole.

[0014] The present invention is further configured such that a motor is fixedly mounted at the bottom end of the mounting bracket, and the output end of the motor is connected to the end of the rotating shaft via a transmission belt.

[0015] Preferably, a motor is used to drive the shaft to rotate.

[0016] The present invention is further configured such that a third telescopic column for controlling the lifting and lowering of the movable lower mold is installed below the base.

[0017] Preferably, the lifting and lowering of the movable lower mold is controlled by a third telescopic column.

[0018] The present invention is further configured such that the fixing plate will not cause the soles to detach from the fixing mold when passing through the two soles.

[0019] Preferably, the sole of the shoe should not be pushed out of the fixed lower mold during the downward movement of the fixed plate.

[0020] The present invention is further configured such that the fixing plate remains parallel to the soles after passing through the two soles.

[0021] Preferably, the fixing plate and the sliding plate can simultaneously clamp the two shoe soles.

[0022] In summary, the present invention has the following main advantages:

[0023] This invention features a rotating clamping mechanism on one side of the lower mold. After the upper and lower molds separate, the movable lower mold located in the middle descends, and the clamping mechanism moves to clamp the shoe sole between the shoe soles, automatically realizing the removal of the shoe sole material. This facilitates the demolding of the shoe sole while significantly reducing the labor intensity of workers. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] First embodiment:

[0035] Please refer to a vulcanizing machine for producing rubber shoe soles. Figure 1-6It includes a base 1, on which two fixed lower molds 3 are fixedly connected, and a movable lower mold 4 is slidably arranged between the two fixed lower molds 3 in the vertical direction. Specifically, the two fixed lower molds 3 and the movable lower mold 4 together form a lower mold that cooperates with the upper mold 2, thereby realizing the forming of the shoe sole body 16.

[0036] Specifically, the upper mold 2 is connected to the base 1 by multiple second telescopic columns 14. In this embodiment, a total of four second telescopic columns 14 are provided, which are used to connect the four corners of the upper mold 2, thereby stably controlling the up and down movement of the upper mold 2. When the movable lower mold 4 is not lowered, it can combine with the two fixed lower molds 3 and cooperate with the upper mold 2. When the movable lower mold 4 is lowered, the sole of the shoe will detach from the movable lower mold 4 and remain in the fixed lower mold 3.

[0037] It also includes a mounting frame 5, which is fixedly connected to one side of one of the fixed lower molds 3, and a clamping mechanism for clamping the shoe sole is rotatably connected to the mounting frame 5.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 1-4 The top of the mounting frame 5 is rotatably connected to a rotating shaft 7, and a rotating rod 8 is fixedly connected to the rotating shaft 7 radially. Specifically, after the second telescopic column 14 lifts the upper mold 2, the upper mold 2 will not interfere with the rotation of the rotating rod 8. A connecting plate 9 is fixedly connected to the end of the rotating rod 8 away from the rotating shaft 7. The connecting plate 9 is fixedly connected to a parallel fixed plate 11 through a guide rod 10. A sliding plate 12 is slidably connected between the fixed plate 11 and the connecting plate 9. A first telescopic column 13 for controlling the sliding of the sliding plate 12 is installed on the connecting plate 9 facing the sliding plate 12. The two shoe soles are clamped by the fixed plate 11 and the sliding plate 12.

[0039] Specifically, a motor 6 is fixedly installed at the bottom of the mounting bracket 5. The output end of the motor 6 is connected to the end of the rotating shaft 7 via a transmission belt, and the rotating shaft 7 is driven to rotate by the motor 6.

[0040] Furthermore, when the sliding plate 12 and the connecting plate 9 come into contact with each other, the distance between the fixed plate 11 and the sliding plate 12 is greater than the thickness of the sole, so as to avoid the sole being too thick to be clamped. Specifically, the width of both the fixed plate 11 and the sliding plate 12 is greater than the distance between the soles of the two fixed lower molds 3, so that the fixed plate 11 and the sliding plate 12 can clamp the edge of the sole.

[0041] Second embodiment:

[0042] Please refer to a vulcanizing machine for producing rubber shoe soles. Figure 1-6 Based on the first embodiment, the difference from the first embodiment is that the base 1 is equipped with a third telescopic column 15 for controlling the lifting and lowering of the movable lower mold 4 below the movable lower mold 4, and the lifting and lowering of the movable lower mold 4 is controlled by the third telescopic column 15.

[0043] Furthermore, when the fixing plate 11 passes through the space between the two soles, it will not cause the soles to detach from the fixing lower mold 3, thus preventing the soles from being pushed out of the fixing lower mold 3 during the downward movement of the fixing plate 11. After passing through the two soles, the fixing plate 11 remains parallel to the soles, allowing the fixing plate 11 and the sliding plate 12 to clamp the two soles simultaneously.

[0044] In practical operation, this utility model is as follows:

[0045] After the sole is formed, the upper mold 2 moves upward away from the fixed lower mold 3 and the movable lower mold 4 under the action of the second telescopic column 14. Then the movable lower mold 4 moves downward under the action of the third telescopic column 15, causing the sole and the movable lower mold 4 to separate from each other. At this time, the upper mold 2 has moved upward to a position that will not interfere with the rotation of the rotating rod 8.

[0046] Driven by the motor 6, the rotating rod 8 rotates towards the movable lower mold 4. After the fixed plate 11 contacts the sole, it presses down on the edge of the sole, causing the sole to deform elastically. After the sole is deformed, the fixed plate 11 can pass through the space between the two soles and move to the bottom between the two soles. Then, the first telescopic column 13 extends, causing the sliding plate 12 to slide towards the fixed plate 11, so that the fixed plate 11 and the sliding plate 12 clamp the edge of the sole. The motor 6 works in the opposite direction, causing the rotating rod 8 to flip and reset. When the sole leaves the space between the upper mold 2 and the fixed lower mold 3, the first telescopic column 13 resets, causing the sole to fall onto the collection box or conveyor belt under its own weight, thus realizing the automatic picking of the sole.

[0047] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
