Description

Technical Field

[0001] The present application relates to the field of shoe production, and in particular to a hot pressing mold for shoe soles and a method for producing shoe soles. Background Art

[0002] With the development of the footwear and apparel industry, the variety of shoe soles is increasing. Some soles have a shield at the toe area. The shield is fixed to the edge of the sole at the toe. When the sole and upper are connected together, the shield is fixed to the toe area of ​​the upper with glue. The production of soles generally uses a hot press mold. The sole material is placed in the hot press mold, and then the hot press mold is sent into a hot press to heat and press, so that the sole material melts and takes the shape of the sole.

[0003] The current related art discloses a hot pressing mold for a shoe sole, comprising an upper mold and a lower mold arranged relative to each other. The top surface of the lower mold is provided with a baffle groove that matches the shape of the baffle, and the bottom surface of the upper mold is provided with a sole groove that matches the shape of the sole. The material is placed on the top side of the lower mold, and then the upper mold is placed on the lower mold, so that the baffle groove is located at the toe part of the sole groove and is interconnected, while the material enters the sole groove. The hot pressing mold is then sent into a hot press, so that the material melts and fills the sole groove and the baffle groove. The hot pressing mold is then removed from the hot press and cooled. After the material cools, the sole and baffle are formed to be connected to each other.

[0004] Regarding the aforementioned related technologies, the inventors believe that the positions of the sole and the baffle on the shoe are different, which may require the baffle and the shoe to have different properties. For example, the sole needs to be wear-resistant and resilient, while the baffle needs to be dirt-resistant. Furthermore, the baffle and the sole may need to be different colors. When the sole and the baffle have different properties or colors, the materials used for the sole and the baffle are generally different. When two different materials are placed in a hot press mold for hot pressing, the two materials will mix and fill the grooves of the sole and the baffle, making it difficult to hot press the baffle and the sole made of different materials. Summary of the Invention

[0005] In order to facilitate the hot pressing of baffles and soles made of different materials, the present application provides a hot pressing mold for soles and a sole production method.

[0006] The present application provides a hot pressing mold for soles and a method for producing soles, which adopt the following technical solutions:

[0007] A hot pressing mold for a sole comprises an upper mold and a lower mold arranged relatively to each other, the top surface of the lower mold being provided with a baffle groove adapted to the shape of the baffle, the bottom surface of the upper mold being provided with a sole groove adapted to the shape of the sole, when the bottom surface of the upper mold and the top surface of the lower mold are in contact with each other, the baffle groove is connected to the sole groove, and the baffle groove is located at the toe part of the sole groove, a discharge plate is provided between the lower mold and the upper mold, the discharge plate being provided with a discharge port connected to the baffle groove, and the top surface of the discharge plate being provided with a shielding plate.

[0022] By adopting the above technical solution, the limiting rod supports the second support rod and the third support rod, thereby reducing the possibility of damage caused by the blade contacting the first circular knife after the elastic ring drives the third support rod to move toward the second support rod. When the first circular knife cuts the material that exceeds the baffle groove, a gap is left between the first circular knife and the side wall of the first sub-plate close to the second sub-plate, so that after the first circular knife cuts, part of the material that exceeds the baffle groove remains connected to the baffle inside the baffle groove. The second circular knife moves with the first circular knife, and driven by the elastic ring, the second circular knife presses against the side of the first sub-plate close to the second sub-plate, so that the material that exceeds the baffle groove is cut again, thereby reducing the possibility of damage caused by the first circular knife cutting the side wall of the first sub-plate close to the second sub-plate.

DETAILED DESCRIPTION

[0049] The following is combined with Figure 1-11 This application is described in further detail.

[0050] Example 1.

[0051] The embodiments of the present application disclose a hot pressing mold for a sole 1 and a method for producing the sole 1 .

[0052] Reference Figure 1 , a hot pressing mold for a sole 1, the present application is used to produce the sole 1, and a baffle 2 is provided at the edge of the sole 1 at the toe. The baffle 2 and the sole 1 are hot pressed to form.

[0053] Reference Figure 2 A hot pressing mold for a sole 1 includes, from bottom to top, a lower mold 5, a discharge plate 6, a shielding plate 7 and an upper mold 8.

[0054] Reference Figure 3 、 Figure 4 The lower mold 5 includes a first lower mold plate 51, a second lower mold plate 52, and a sole block 53. One side of the second lower mold plate 52 is flipped and connected to one side of the first lower mold plate 51, and the second lower mold plate 52 is located on the side of the first lower mold plate 51 close to the upper mold 8. The sole block 53 is fixedly mounted on the side of the first lower mold plate 51 close to the upper mold 8. The second lower mold plate 52 is provided with a sole opening 3 for the sole block 53 to pass through. The sole opening 3 is adapted to the shape of the sole 1.

[0055] Figure 4 、 Figure 5 The sole block 53 is a hollow structure, which is beneficial to reducing the weight of the lower mold 5. A gap is left between the sole block 53 and the inner wall of the sole opening 3 at the toe portion, and the bottom side of the first lower template 51 blocking the gap forms a blocking groove 4.

[0056] After the baffle 2 material is melted, it is placed inside the baffle groove 4. After the baffle 2 material is cooled and solidified, the baffle 2 is formed inside the baffle groove 4. The second lower template 52 is pulled away from the first lower template 51 to facilitate the removal of the baffle 2 from the baffle groove 4.

[0057] Reference Figure 5 The discharge plate 6 includes a first sub-plate 61, a second sub-plate 62 and a pressing block 63. The first sub-plate 61 is fixedly mounted on the top surface of the second lower template 52, and the second sub-plate 62 is fixedly mounted on the bottom surface of the shielding plate 7.

[0058] Reference Figure 3 、 Figure 6 When the shielding plate 7 is placed on the top surface of the second lower template 52, one side of the first sub-plate 61 and one side of the second sub-plate 62 are in contact with each other. A placement groove 9 is provided on the side of the first sub-plate 61 close to the second sub-plate 62, and the placement groove 9 passes through the first sub-plate 61 in the height direction. The lower edge of the placement groove 9 is aligned with the edge of the sole opening 3 at the toe part. The pressing block 63 is fixedly installed on the side of the second sub-plate 62 close to the first sub-plate 61, and the pressing block 63 is passed through the inside of the placement groove 9. After the first sub-plate 61 and the second sub-plate 62 are in contact with each other, a gap is left between the side wall of the pressing block 63 and the inner wall of the placement groove 9, and the discharge port 26 is enclosed between the side wall of the pressing block 63 and the inner wall of the placement groove 9.

[0059] After the baffle 2 material is placed in the placement groove 9, the shielding plate 7 is placed on top of the second lower mold plate 52, so that the first sub-plate 61 and the second sub-plate 62 are pressed against each other. The pressing block 63 enters the placement groove 9 to squeeze the baffle 2 material, placing it within the discharge port 26. The baffle 2 material then melts and flows into the baffle groove 4, forming the baffle 2 within the baffle groove 4. Simultaneously, as the baffle 2 material melts, the shielding plate 7 blocks the top of the discharge port 26, thereby reducing the possibility of the melted baffle 2 material coming into contact with the upper mold 8.

[0060] Reference Figure 7 、 Figure 8The bottom surface of the upper mold 8 is provided with a sole groove 10, and the bottom surface of the upper mold 8 is also provided with a mounting groove 11 that is compatible with the first sub-plate 61. A third sub-plate 12 is fixedly mounted on the top surface of the shielding plate 7, and the third sub-plate 12 is compatible with the mounting groove 11. When the shielding plate 7 is placed on the top surface of the lower mold 5 and the upper mold 8 covers the top surface of the shielding plate 7, the third sub-plate 12 enters the mounting groove 11, thereby facilitating the upper mold 8 to cover the top surface of the shielding plate 7. When the upper mold 8 directly covers the top surface of the lower mold 5, the first sub-plate 61 enters the mounting groove 11, thereby facilitating the upper mold 8 to cover the top surface of the lower mold 5. When the upper mold 8 directly covers the top surface of the lower mold 5, the baffle groove 4 is connected to the sole groove 10, and the baffle groove 4 is located along the edge of the sole groove 10 at the toe portion. The sole 1 material is melted to fill the sole groove 10 and then cooled, so that the sole 1 is formed inside the sole groove 10 , and the sole 1 is connected to the baffle 2 inside the baffle groove 4 .

[0061] Reference Figure 6 、 Figure 8 Positioning rods 13 are fixedly mounted on the bottom surface of the second sub-plate 62 and the bottom surface of the upper mold 8. Positioning slots 14 are formed on the top surface of the lower mold 5 and the top surface of the shielding plate 7 for the positioning rods 13 to pass through. With the positioning rods 13 passing through the positioning slots 14, the lower mold 5, the shielding plate 7, and the upper mold 8 can be easily aligned and stacked together.

[0062] A method for producing a sole 1, using a hot pressing mold of a sole 1 according to an embodiment of the present application, comprises the following steps:

[0063] S1. Place the feeding plate and the shielding plate 7 on the top side of the lower mold 5 in sequence, put the baffle 2 material into the discharge port 26, and then cover the upper mold 8 on the shielding plate 7.

[0064] S2, hot pressing the hot pressing mold, the baffle 2 material melts and enters the baffle groove 4;

[0065] S3, waiting for the material entering the baffle groove 4 to cool and solidify, then opening the upper mold 8, then removing the shielding plate 7 and the feeding plate, and cutting off the material exceeding the baffle groove 4 to form the baffle 2;

[0066] S4, placing the material of the sole 1 into the lower mold 5, and then covering the upper mold 8 on the lower mold 5, allowing the material of the sole 1 to enter the interior of the sole groove 10;

[0067] S5, hot pressing the hot pressing mold, the sole 1 material melts and fills the sole groove 10;

[0068] S6, waiting for the material entering the sole groove 10 to cool and solidify, opening the upper mold 8, and connecting the sole 1 to the baffle 2;

[0069] S7, take out the sole 1 and the baffle 2 from the lower mold 5, cut and trim the edges of the sole 1 and the baffle 2, and thus complete the production of the sole 1

[0070] The implementation principle of a hot pressing mold for a sole 1 and a method for producing the sole 1 according to an embodiment of the present application is as follows: when a baffle 2 made of different materials and a sole 1 need to be connected together by hot pressing, the baffle 2 material is placed inside the placement groove 9, and then the shielding plate 7 is covered on the top surface of the lower mold 5. The pressing block 63 enters the placement groove 9, thereby pressing the baffle 2 material against the inner wall of the placement groove 9, and the peripheral side walls of the baffle 2 and the inner wall of the placement groove 9 form a discharge port 26. Thereafter, the upper mold 8 is covered on the top surface of the shielding plate 7 and sent into the hot press. The baffle 2 material melts in the discharge port 26 and flows into the baffle groove 4. The hot pressing mold is then taken out of the hot press for cooling, and the baffle 2 is formed after the material inside the baffle groove 4 solidifies.

[0071] After the material inside the baffle groove 4 solidifies to form the baffle 2, the upper mold 8 is removed, and the shielding plate 7 is removed from the lower mold 5. The material that exceeds the baffle groove 4 is then cut off, and the sole 1 material is placed on the top surface of the lower mold 5, located on the top surface of the sole block 53 near the heel. The upper mold 8 is then placed on the top surface of the lower mold 5, allowing the sole 1 material to enter the sole groove 10, and the baffle groove 4 and the sole groove 10 are connected to each other. The hot pressing mold is then placed in a hot press. After the sole 1 material melts, it gradually fills the sole groove 10 from the part near the heel. After the sole 1 material fills the sole groove 10, the hot pressing mold is removed and cooled. After the sole 1 material cools, the sole 1 is formed, and the sole 1 and the baffle 2 are connected to each other. Thereafter, the upper mold 8 and the second lower mold plate 52 are opened, thereby removing the sole 1 and the baffle 2 from the hot pressing mold, thereby facilitating hot pressing of the baffle 2 and the sole 1 made of different materials.

[0072] The sole 1 material gradually fills the sole groove 10 from the heel to the toe, so that the sole 1 material can be removed for cooling after filling the sole groove 10, thereby reducing the mixing of the sole 1 material and the baffle 2 material after melting.

The first gear 2021 is fixedly mounted on the rotating shaft of the motor 201, and the second gear 2022 is fixedly mounted on the rotating rod 205. The transmission belt 2023 engages with the first gear 2021 and the second gear 2022. The sliding rod 18 moves along the sliding opening 17 to allow the cutting mechanism 20 to move along the side wall of the first sub-plate 61 close to the second sub-plate 62 for cutting.

[0077] Insert the first support rod 16 into the positioning groove 14, so that the slide 15 is mounted on the top surface of the second lower template 52. Then, insert the slide rod 18 into the sliding opening 17, and then push the sliding seat 19 to allow the slide rod 18 to move inside the sliding opening 17, so that the sliding seat 19 moves along the sliding opening 17. When the sliding seat 19 moves, it drives the cutting mechanism 20 to move. When the cutting mechanism 20 moves, start the motor 201, and the motor 201 drives the first gear 2021 to rotate. The first gear 2021 drives the second gear 2022 to rotate through the transmission belt 2023. The second gear 2022 drives the rotating rod 205 to rotate, and the rotating rod 205 drives the first circular knife 206 to rotate. When the sliding seat 19 moves along the sliding opening 17, the first circular knife 206 moves along the side wall of the first sub-plate 61 close to the second sub-plate 62, thereby cutting the material that exceeds the baffle groove 4. The portion of the sliding opening 17 aligned with the placement groove 9 is bent, so that the sliding rod 18 can drive the first circular knife 206 to enter the placement groove 9 for cutting when the sliding opening 17 slides.

[0078] Reference Figure 11The second support rod 203 is provided with a third support rod 21 and an elastic ring 22. One end of the third support rod 21 is hinged to the rod body of the second support rod 203, and the other end of the third support rod 21 is fixedly mounted with a connecting rod 23 parallel to the rotating rod 205. The elastic ring 22 is sleeved between the second support rod 203 and the third support rod 21. A limit rod 24 is fixedly mounted on the rod body of the second support rod 203. The elastic ring 22 is used to drive the third support rod 21 to rotate toward the second support rod 203, and the limit rod 24 is used to limit the contact between the second support rod 203 and the third support rod 21. A second circular knife 25 is fixedly mounted on the end of the connecting rod 23 away from the third support rod 21. The second circular knife 25 is used to re-cut the portion cut by the first circular knife 206.

[0079] When using the cutting mechanism 20 to cut material extending beyond the baffle slot 4, the first circular blade 206 is positioned close to the sidewall of the first sub-plate 61 near the second sub-plate 62, and the first circular blade 206 does not contact the first sub-plate 61, thereby minimizing the risk of the first circular blade 206 damaging the first sub-plate 61. Simultaneously, the elastic ring 22 drives the third support rod 21 to rotate toward the second support rod 203, causing the second circular blade 25 to abut against the side of the first sub-plate 61 near the second sub-plate 62. After the first circular blade 206 cuts the material extending beyond the baffle slot 4, the material still partially connects to the baffle 2 within the baffle slot 4. This material can be cut again by the second circular blade 25, facilitating removal of the material extending beyond the baffle slot 4.

[0080] The first circular knife 206 is arranged to have a surface close to the rotating rod 205 that is gradually inclined from the middle to the circumference, so that the first circular knife 206 can open the material outside the baffle groove 4 and the baffle 2 inside the baffle groove 4 after cutting, and then the second circular knife 25 can enter between the material outside the baffle groove 4 and the baffle 2 inside the baffle groove 4 for cutting.

[0081] The operating principle of a hot-pressing mold and a method for producing a sole 1 according to an embodiment of the present application is as follows: After the material of the baffle 2 cools and solidifies within the baffle groove 4, some excess material of the baffle 2 will protrude beyond the baffle groove 4. The movable seat is pushed to slide on the slide plate 15, thereby causing the first circular blade 206 and the second circular blade 25 to sequentially cut the material that protrudes beyond the baffle groove 4. By sequentially cutting the material that protrudes beyond the baffle groove 4 by the first circular blade 206 and the second circular blade 25, the chance of the melted sole 1 material mixing with the material of the baffle 2 is reduced.

[0082] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
