Description

Technical Field

[0001] This utility model relates to the field of skateboard shoes, and more particularly to a production apparatus for skateboard shoes. Background Technology

[0002] Skate shoes are shoes specifically designed for skateboarding. Their main features include a flat sole, durable materials, cushioning, and protective design. Current skate shoe sole production molds typically use a traditional two-mold molding process, making it difficult to incorporate a support plate within a single molded sole. Instead, a support plate is often laminated between two sole layers. This type of sole has weaker stability, and the two sole layers are prone to cracking under the force of the support plate, resulting in skate shoes with poor sole support and cushioning.

[0003] Chinese Patent Application No. 201820849077.X discloses a thermoforming mold for shoe soles that facilitates the removal of edge material. The mold includes an upper mold and a lower mold. The lower mold has a finished product area. The shoe sole is formed by pressing the finished product protrusion of the upper mold against the finished product area of ​​the lower mold. The outer side of the finished product area of ​​the lower mold has a horizontal die opening without sidewalls. A 0.8 mm wide straight wall is made at the die opening where there are sidewalls, and a small groove is made around the perimeter to increase the thickness of the edge material. A 0.8 mm wide flat wall is made at the die opening without sidewalls, and a small groove is made around the perimeter to further increase the thickness of the edge material. This mold cannot incorporate a support plate within the integrally formed shoe sole; instead, a support plate is composited between two layers of the sole. This structure results in a less stable sole, and the two layers are prone to cracking under the force of the support plate, leading to poor support and cushioning in the produced skateboard shoes. Utility Model Content

[0004] Therefore, to address the aforementioned problems, this utility model proposes a production device for skateboard shoes. It solves the technical problem that it is difficult to install a support plate within the one-piece molded sole, resulting in poor support and cushioning in the produced soles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A production apparatus for skateboard shoes includes a mold body, the sole formed by the mold body having at least one support plate, the mold body including a first mold and a second mold, the mold body having a mold cavity, the first mold having a first support portion, the first support portion being able to support or fix the support plate in the middle of the mold cavity, the inner sidewall of the mold body having at least one protrusion, the side edge of the support plate being able to abut against the protrusion, such that one or both sides of the formed sole have grooves.

[0007] Further:

[0008] The first support portion includes at least one first support column disposed within the first mold.

[0009] The first support portion includes at least one support block disposed within the first mold.

[0010] The first support includes a support block and at least two first support columns, with the support plate located between the first support columns.

[0011] The number of protrusions is two, and the two protrusions are located on both sides of the mold body.

[0012] The mold body is provided with a material discharge port, and the mold body is provided with an exhaust hole, which is connected to the mold cavity and the outside.

[0013] The first mold and the second mold have interlocking slots and inserts along their side edges.

[0014] The second mold is provided with a second support part, and the first support part and the second support part can clamp and fix the support plate.

[0015] The second support includes at least one second support column, which is capable of abutting against one side of the support plate.

[0016] The second support column includes a fixed column fixed to the second mold, a buffer column slidable to the fixed column, and a buffer spring connecting the fixed column and the buffer column.

[0017] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0018] The mold body of this utility model has a first support part that supports or fixes a support plate. During material foaming, it can completely encapsulate the support plate. The support plate is located within the one-piece molded sole, greatly improving the sole's strength and making it less prone to damage. Compared to traditional composite soles, it only requires one-time molding, significantly improving production efficiency. Simultaneously, the inner wall of the mold body has protrusions that provide a certain degree of fixation for the support plate and create grooves on one or both sides of the sole. This provides excellent shock absorption and cushioning on the sides of the sole, greatly improving its performance. A cushioning groove can also be formed at the first support part, further enhancing the overall shock absorption and support of the sole. Consumers can also see the support plate from the outside, making the sole more aesthetically pleasing, increasing its perceived quality, and stimulating consumer desire to purchase. Furthermore, the structure of the first support column allows for the formation of shock-absorbing cushioning holes on the sole. Firstly, a support block structure is adopted, which can form a shock-absorbing opening on the sole. Secondly, the support block and the first support column are set simultaneously to improve the support and shock absorption effect of the support plate. Thirdly, there are two protrusions, which make the grooves on the sole symmetrical, resulting in better shock absorption. At the same time, the two protrusions have a good fixing effect on the support plate. Fourthly, the slots and inserts have positioning and sealing functions. Fifthly, the second support part, the first support part, and the protrusions fix the support plate, so that the support plate will not move during the operation of the equipment. Sixthly, the second support column can form a through hole on the sole, so that there are through holes on both sides of the support plate, improving the shock absorption effect of the sole. Sixthly, the second support column includes a movable buffer column. When the first mold and the second mold are not fully closed, the buffer column can abut against the support plate for fixation, improving the fixation effect. Attached Figure Description
