Description

Technical Field

[0001] The utility model relates to the technical field of sole moulds, in particular to a sole mould used for integrally forming a popcorn sole and a shoe upper. Background Art

[0002] Popcorn soles have many advantages such as soft texture, good elasticity, good cushioning performance, low energy loss under pressure, good durability, and good thermal insulation performance. The surface presents a granular appearance, so some shoes with popcorn soles are favored by many consumers. In the traditional production of shoes with popcorn soles, the popcorn soles are generally produced separately first, and then the uppers and popcorn soles are synthesized by manual gluing. However, such manual gluing bonding method will add a gluing bonding process and corresponding labor costs, and because glue needs to be used, it is not environmentally friendly. Therefore, there is a need for a popcorn sole mold that can realize the integrated molding of the upper and popcorn sole. In view of this, this issue has been studied in depth, and thus this case has arisen. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a sole mold for integrally forming a popcorn sole and an upper, which can save a glue brushing and laminating process, and is conducive to reducing labor costs and improving production efficiency. It does not require the use of glue and is more environmentally friendly.

[0005] Furthermore, the locking mechanisms are multiple and are arranged at intervals around the circumference of the middle frame.

[0006] Furthermore, the locking mechanism includes a locking bolt and a locking nut, a first locking hole is provided on the upper mounting plate, a second locking hole is provided on the middle frame, and a third locking hole is provided on the shoe last. The locking bolt can be detachably passed through the first locking hole, the second locking hole and the third locking hole in sequence and is threadedly connected to the locking nut.

[0007] Furthermore, a plurality of second locking plates are fixedly provided at the bottom edge of the middle frame, and second locking holes are provided on the second locking plates.

[0008] Furthermore, a third locking plate is fixedly provided on the top of the shoe last, and a plurality of third locking holes are provided on the third locking plate.

[0009] Furthermore, the bottom surface of the heel of the shoe upper is also provided with a plurality of heel positioning holes, and the bottom surface of the sole of the shoe upper is also provided with a plurality of sole positioning holes.

DETAILED DESCRIPTION

[0022] The present invention is further described below through specific implementation methods.

[0023] like Figures 1 to 6 As shown, the utility model discloses a sole mold for integrally forming a popcorn sole and an upper, comprising an upper mold 1 and a lower mold 2 which are arranged up and down and detachably connected, the lower mold 2 comprising a lower mounting plate 21 and a mold core 22 fixedly arranged on the upper end of the lower mounting plate 21, the upper mold 1 comprising a shoe last 11, a middle frame 12 and an upper mounting plate 13 which are arranged in sequence from top to bottom, the shoe last 11 and the middle frame 12 are both detachably locked and mounted on the upper mounting plate 13 by a locking mechanism 3, the shoe last 11 is sleeved with an upper 4, a sole forming cavity 5 is formed between the upper 4, the middle frame 12 and the mold core 22, the shoe last 11 is provided with a feed hole 111 which passes through its upper and lower ends, and the bottom surface of the heel of the upper 4 is provided with a connecting hole 41 for connecting the feed hole 111 and the sole forming cavity 5.

[0024] By setting the shoe last 11, it is convenient to put the shoe upper 4 on the shoe last 11, and make the shoe upper 4 stably on the shoe last 11. When the shoe last 11 and the middle frame 12 are stably mounted on the upper mounting plate 13 through the locking mechanism 3, the shoe upper 4 can be stably located at the upper end of the middle frame 12, and the sole forming cavity 5 can be formed between the shoe upper 4, the middle frame 12 and the mold core 22. At this time, the bottom surface of the shoe upper 4 will become the sole The top surface of the molding cavity 5, and the ETPU popcorn sole material can enter the sole molding cavity 5 through the feed hole 111 and the connecting hole 41. After the popcorn sole is formed, it can be directly fixed and bonded to the bottom surface of the upper 4, so as to realize the integral molding of the sole and the upper 4. As a result, a gluing and bonding process can be saved, which is beneficial to reducing labor costs and improving production efficiency. The fixation between the popcorn sole and the upper 4 does not require the use of glue, which is more environmentally friendly.

[0025] The locking mechanisms 3 are multiple and are arranged at intervals around the circumference of the middle frame 12. Preferably, the number of the locking mechanisms 3 is 6-8. Specifically, the locking mechanism 3 includes a locking bolt 31 and a locking nut 32. The upper mounting plate 13 is provided with a first locking hole 131, the middle frame 12 is provided with a second locking hole 122, and the shoe last 11 is provided with a third locking hole 113. The locking bolt 31 can be detachably passed through the first locking hole 131, the second locking hole 122 and the third locking hole 113 in sequence and screwed with the locking nut 32. Specifically, a plurality of second locking plates 121 are fixedly provided at the bottom edge of the middle frame 12, and the second locking plates 121 are provided with the second locking holes 122. A third locking plate 112 is fixedly provided at the top of the shoe last 11, and the third locking plate 112 is provided with a plurality of third locking holes 113. Correspondingly, the number of the first locking holes 131, the second locking holes 122 and the third locking holes 113 are all 6-8. In this way, it is easy to achieve stable installation between the shoe last 11, the middle frame 12 and the upper mounting plate 13.

[0026] In addition, the bottom surface of the heel of the upper 4 is also provided with a plurality of heel positioning holes 42, and the bottom surface of the sole of the upper 4 is also provided with a plurality of sole positioning holes 43. The plurality of heel positioning holes 42 are evenly arranged along the circumferential direction of the connecting hole 41, and the plurality of sole positioning holes 43 are distributed in an array. Preferably, the shapes of the heel positioning holes 42 and the sole positioning holes 43 are circular, elliptical, diamond-shaped, square or triangular. Preferably, the number of the heel positioning holes 42 is 4-8, and the number of the sole positioning holes 43 is 6-10. Therefore, when the ETPU popcorn sole material enters the sole molding cavity 5, the heel positioning holes 42 and the sole positioning holes 43 will also be filled, so that the popcorn sole is formed with a plurality of heel positioning protrusions and a plurality of sole positioning protrusions on the bottom surface of the upper 4, which is beneficial to further improve the stability of the connection between the popcorn sole and the upper 4.

[0027] In addition, a contour fitting edge 123 matching the bottom edge of the shoe upper 4 is provided at the upper end of the middle frame 12 to better ensure a tight fit between the shoe upper 4 and the middle frame 12 .

[0028] In addition, the upper mounting plate 13 is connected to the lower mounting plate 21 by bolts.

[0029] The above are only some specific implementation methods of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
