Description

Technical Field

[0001] The utility model relates to the field of sole production, in particular to a die-casting mold for anti-slip sole production. Background Technique

[0002] In the footwear manufacturing industry, the production of anti-slip soles is a crucial link, which directly affects the safety and comfort of shoes. However, traditional anti-slip sole mold designs mostly adopt an integral structure, that is, the lower mold of the mold is an integral body and cannot be disassembled. Although this design can ensure the stability and consistency of the sole during the molding process, it faces many challenges during the demolding stage.

[0003] Specifically, after injection molding or die-casting molding of the integral anti-slip sole mold, since the sole material closely adheres to the inside of the mold, especially the complex anti-slip texture part, the demolding process becomes particularly difficult. Operators often need to spend a lot of time and energy on manual demolding, which is not only inefficient but also easy to damage the mold and the sole, affecting the appearance quality and service life of the product.

[0004] Therefore, it is necessary to provide a new die-casting mold for anti-slip sole production to solve the above technical problems. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a die-casting mold for anti-slip sole production.

A connecting seat is installed on one side of the base. Grooves are opened at the tops of the base and the connecting seat. The base, the connecting seat and the grooves form a lower mold. One end of the base is rotatably connected to the cover plate. An upper mold core is installed in the middle of the cover plate. A transmission mechanism is installed inside the base, and the transmission mechanism is cooperatively installed with the connecting seat.

The shape and distribution of the convex patterns 10 are customized according to the design requirements of the anti-slip sole, including but not limited to wavy, diamond-shaped, herringbone, etc., to enhance the anti-slip effect of the sole

[0025] Please refer to Figures 3-4 , the middle of the cover plate 4 is slidably connected to the upper die core 12. The top of the upper die core 12 is fixedly connected to a pressure plate 6. Positioning columns 7 are fixedly connected to the four corners of the pressure plate 6. A plurality of the positioning columns 7 are all slidably connected to the cover plate 4. Avoidance grooves 8 are provided at the positions of the cover plate 4 where the positioning columns 7 are located. A return spring 9 is sleeved on the outer wall of the positioning column 7. The top of the return spring 9 is fixedly connected to the bottom end of the pressure plate 6. The bottom end of the return spring 9 is fixedly connected to the inside of the avoidance groove 8

[0026] Please refer to Figures 3-4, the transmission mechanism 5 includes: a fixed shaft 51, a driving sprocket 52, a driven sprocket 53, a driving bevel gear 54, and a worm 55. A fixed shaft 51 is fixedly connected to the rotational connection between the cover plate 4 and the base 1. One end of the fixed shaft 51 is fixedly connected to the driving sprocket 52. A driven sprocket 53 is rotatably connected inside the base 1. The driving sprocket 52 and the driven sprocket 53 are connected by chain drive. One side of the driven sprocket 53 is fixedly connected to the driving bevel gear 54. A worm 55 is rotatably connected inside the base 1. One end of the worm 55 is fixedly connected to a driven bevel gear 56. The driving bevel gear 54 and the driven bevel gear 56 are meshed. One end of the connecting seat 2 is symmetrically and fixedly connected with ear plates 57. One side of an ear plate 57 close to the worm 55 is fixedly connected with a worm gear 58. The worm 55 and the worm gear 58 are meshed. The two ear plates 57 are rotatably connected to the inside of the base 1.

[0027] The working principle of the die for producing anti-slip shoe soles provided by the present utility model is as follows:

[0028] I. In the initial state, the die is in a closed state, that is, the base 1 and the cover plate 4 are closely attached. A closed cavity is formed between the upper die core and the lower die (formed by the base 1, the connecting seat 2, and the groove 3) for injecting or pressing the anti-slip shoe sole material. At this time, the transmission mechanism 5 is in a static state and does not participate in the closing operation of the die, but only serves as a driving device for the subsequent demoulding process.

[0029] II. Demoulding preparation stage

[0030] When the shoe sole material is solidified and formed in the die, demoulding operation is required. At this time, the operator first manually turns the handle 11 of the cover plate 4 to make the cover plate 4 rotate around its rotational connection with the base 1. This action is converted into the corresponding movement of the connecting seat 2 through the precise design of the transmission mechanism 5.

[0031] III. The transmission mechanism 5 works

[0032] Specifically, when the cover plate 4 rotates, the fixed shaft 51 fixedly connected to the rotational connection between the cover plate 4 and the base 1 rotates accordingly, and then drives the driving sprocket 52 to rotate. The driving sprocket 52 is connected to the driven sprocket 53 by chain drive, so the driven sprocket 53 also rotates accordingly. One side of the driven sprocket 53 is fixedly connected to the driving bevel gear 54. As the driven sprocket 53 rotates, the driving bevel gear 54 drives the meshed driven bevel gear 56 to rotate. The driven bevel gear 56 is fixedly connected to one end of the worm 55, so the worm 55 also starts to rotate.

[0033] IV. The connecting seat 2 flips

[0034] The rotation of the worm 55 further drives the rotation of the worm wheel 58 meshing therewith; the worm wheel 58 is fixedly connected to the ear plate 57 at one end of the connecting seat 2. Therefore, the connecting seat 2 starts to turn downward under the driving action of the worm wheel 58 and the worm 55; according to the design requirements, when the cover plate 4 rotates 90 degrees, the connecting seat 2 rotates 45 degrees. This precise angle control enables the heel part of the sole (i.e., the part located in the groove 3 of the connecting seat 2) to be exactly exposed, providing convenience for the subsequent demolding operation;

[0035] V. Demolding of the sole

[0036] After the connecting seat 2 is turned in place, the operator can easily take out the formed anti-slip sole; since the heel part of the sole has been exposed, the demolding process becomes simple and fast, avoiding the problem of difficult demolding caused by the close fitting of the sole material to the inside of the mold in the traditional integral mold.

[0037] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
