Description

Technical Field

[0001] This utility model relates to the field of demolding mechanism technology, specifically to an auxiliary demolding mechanism for shoe molds used in shoe production. Background Technology

[0002] Shoes are items used in daily life to protect and decorate people's feet. They come in various colors and styles, and different shoes can be worn for different occasions.

[0003] Shoes consist of a sole and an upper. During production, the sole needs to be demolded. When in use, the sole material is placed in a shoe mold, and the material is shaped by the high temperature pressing of the upper and lower molds. Because the sole material melts when exposed to high temperatures, the molded sole will be in close contact with the inner wall of the shoe mold due to the heat melting. An adhesive force will be formed between the two, which requires workers to use a lot of force or different tools to remove the sole. Demolding is very troublesome. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides an auxiliary demolding mechanism for shoe molds in shoe production, which has the following beneficial effects:

[0017] This shoe production uses a shoe mold-assisted demolding mechanism. Starting the motor causes the first drive block to rotate, which in turn causes the second rotating shaft to rotate two second drive blocks. This allows the two drive wheels to rotate synchronously in opposite directions on both sides of the bottom mold. The two drive wheels mesh with each other, and through the toothed plate, they drive the bottom mold down along the guide rod, allowing the bottom of the mold to contact the base plate. At this point, the shaped sole extends out of the mold groove and is exposed to the environment, preventing it from tightly contacting the inner wall of the mold groove. This reduces the adhesion force at the sole, making it easier for workers to demold the shaped sole, resulting in high demolding efficiency. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention relates to a shoe mold auxiliary demolding mechanism for shoe production, comprising a base plate 1 and a bottom mold 2. The bottom mold 2 is provided with a mold groove 3. The upper end of the base plate 1 is provided with a base 4 that can be inserted into the mold groove 3. The upper end of the base plate 1 is provided with a plurality of guide rods 5 that penetrate the bottom mold 2.

[0026] Two supports 8 are symmetrically arranged on the upper end of the bottom mold 2 of the base plate 1. A first rotating shaft 9 is rotatably arranged on the top of the support 8. A drive wheel 10 is fixedly arranged at one end of the first rotating shaft 9, and a second driven block 11 is fixedly arranged at the other end of the first rotating shaft 9. Two toothed plates 7 are symmetrically arranged on both sides of the bottom mold 2. The drive wheel 10 meshes with the toothed plates 7. A box 12 located above the base plate 1 is provided on one side of the bottom mold 2. A motor 13 is fixedly arranged on the outside of the box 12. A second rotating shaft 15 is rotatably arranged on the box 12. A second drive block 17 that meshes with the second driven block 11 is provided at both ends of the second rotating shaft 15. A first driven block 16 located inside the box 12 is provided in the middle part of the second rotating shaft 15. A drive shaft that penetrates the box 12 is provided at the output end of the motor 13. A first drive block 14 that meshes with the first driven block 16 is provided at one end of the drive shaft.

[0027] In this embodiment, the sole material is placed in the mold groove 3 so that the sole material is on the base 4, and then the designated upper mold is placed on the bottom mold 2. At this time, the material can be formed into a designated shape in the mold groove 3 by the high temperature pressing of the upper and lower molds.

[0028] When it is necessary to demold the sole, the upper mold is reset (generally, the upper mold is raised to a specified height), and then the motor 13 is started. This causes the first drive block 14 to drive the first driven block 16 to rotate, which in turn causes the second rotating shaft 15 to drive the two second drive blocks 17 to rotate. At this time, the two second drive blocks 17 will drive the two second driven blocks 11 to rotate synchronously in opposite directions through meshing. This allows the two drive wheels 10 to rotate synchronously in opposite directions on both sides of the bottom mold 2. During this process, the bracket 8 can support the first rotating shaft 9, and the two drive wheels 10 can drive the bottom mold 2 to descend along the guide rod 5 through the toothed plate 7 through meshing. This allows the bottom of the bottom mold 2 to contact the bottom plate 1. At this time, the shaped sole on the base 4 will protrude from the mold groove 3 and be exposed to the environment, so that the sole will not be in close contact with the inner wall of the mold groove 3. This reduces the adhesion force at the sole, making it easier for workers to demold the shaped sole. The demolding efficiency is high.

[0029] After the sole is demolded, start motor 13 to reverse the second rotating shaft 15, so that the bottom mold 2 can rise along the second rotating shaft 15 to the specified height. The structure is simple and the operation is convenient.

[0030] The lack of a limiting structure for the bottom mold 2 at the top of the guide rod 5 makes it difficult for the bottom mold 2 to reach the specified height. Multiple guide rods 5 pass through the four corners of the bottom mold 2, and the top of each guide rod 5 is fixedly provided with a limiting block 6 for limiting the bottom mold 2. The guide rod 5 can be a cylindrical structure. The limiting block 6 provides a limiting structure for the bottom mold 2 at the top of the guide rod 5, making it easy for the bottom mold 2 to reach the specified height and making it easy for the bottom mold 2 to reset after descent.

[0031] In this embodiment, two scraping components are symmetrically arranged on the upper end of the bottom mold 2. The scraping components include a driving component and a scraping block 19. The scraping block 19 is fixed to the output end of the driving component and can slide on the bottom mold 2. Two limiting grooves 20 are symmetrically arranged on the upper end of the bottom mold 2. The scraping block 19 can slide inside the limiting grooves 20. The driving component is a telescopic cylinder 18. When the base 4 drives the sole to rise, the telescopic cylinder 18 is activated, which allows the scraping block 19 to slide on the bottom mold 2. Since the inner side of the scraping block 19 is a slope, the scraping block 19 can provide a scraping action on the two ends of the sole on the base 4, making it less likely for the sole to stick to the base 4. This makes it easier for the sole to be demolded on the base 4. The limiting grooves 20 can improve the stability of the scraping block 19 when sliding.

[0032] In this embodiment, the motor 13 can be a servo motor.

[0033] When the parts on the bracket 8 and the housing 12 are damaged, they need to be disassembled. The lower end of the housing 12 is provided with a support rod, and the bottom of the support rod is provided with a positioning plate. The positioning plate is fixed to the upper end of the base plate 1 by screws, and the bracket 8 is fixed to the upper end of the base plate 1 by screws. The screw fixing method has the advantage of convenient assembly, which makes it easy to assemble and disassemble the bracket 8 and the housing 12.
