Abstract
Description
Technical Field
[0001] The present invention relates to a forming die, and particularly to a forming die for the side edge of a sole. Background Art
[0002] Designing textures on the side of the sole can increase the aesthetic appearance of the sole. For the side higher than the upper surface of the sole, a split design is proposed, where the side is wrapped around the sole and then the texture of the side is pressed out after bonding with the sole body. However, the yield rate is too low. It is proposed to improve the forming process by first pressing out the side edge texture and then bonding it with the sole body. However, when directly pressing and forming the plate, the obtained side edge is not easy to wrap around the sole body and the texture is not good. Summary of the Invention
[0003] In view of the technical problems in the background art, the present invention aims to provide a forming die for the side edge of a sole. The movable die, the upper die and the lower die jointly form an extrusion forming cavity, and the forming effect is good.
[0004] To solve the above technical problems, the present invention adopts the following technical solution: The forming die for the side edge of a sole includes a movable die, an upper die and a lower die. The movable die is movably arranged. The upper die is provided with a long strip-shaped opening for the movable die to pass through. The lower die is provided with a texture part. The movable die, the upper die and the lower die jointly form an extrusion forming cavity. When extruding and forming, the edge line of the long strip-shaped opening coincides with the edge line of the movable die.
[0005] In this solution, the movable die, the upper die and the lower die jointly form an extrusion forming cavity. The movable die provides pressure by moving to extrude and form, and no waste will be generated.
[0006] Preferably, the movable die has a pressing part, and the middle part of the pressing part is arched.
[0007] In this solution, the middle part of the pressing part is arched corresponding to the middle part of the side edge being bent, and the side edge can easily wrap around the sole body.
[0008] Preferably, the upper die and the lower die are in concave-convex fit. The upper die is a convex part, and the middle part of the upper die is arched. The lower die is a concave part.
[0009] In this solution, the convex part of the upper die corresponds to the design of the middle part of the side edge being bent, and the concave part of the lower die is convenient for setting the texture part.
[0010] Preferably, the upper die is provided with positioning protrusions on both left and right sides, and the lower die is provided with positioning grooves corresponding to the positioning protrusions.
[0011] In this solution, the positioning grooves are aligned with the positioning protrusions, so that the upper die and the lower die can be accurately assembled together.
[0012] Preferably, the upper die is provided with the positioning protrusions at all four corners, and the lower die is provided with the positioning grooves at all four corners.
[0013] In this solution, the four - corner positioning is accurate.
[0014] Preferably, the positioning groove is provided with an inclined guiding surface, and the positioning protrusion is provided with a fitting surface corresponding to the guiding surface.
[0015] In this solution, during the assembly process, the positioning protrusion is aligned with the positioning groove along the guiding surface, and the alignment is completed during the assembly process, making the assembly convenient.
[0016] The beneficial effects of the present invention are as follows: The movable die, the upper die and the lower die jointly form an extrusion molding cavity. The movement of the movable die provides pressure for extrusion molding, without generating waste. The middle part of the pressing part arches, corresponding to the middle part of the surrounding edge being bent, and the surrounding edge can easily enclose the sole body. Therefore, the present invention has substantial features and progress compared with the prior art. BRIEF DESCRIPTION OF THE DRAWINGS
