Problems solved by technology

This method requires a special ring-shaped welt with an auxiliary sole, and the access to accessories is limited and difficult to process. It is not easy to insert the correct position in the mold during assembly, and a complicated processing and finishing process is required after the finished shoe is taken out of the mold.
In addition, the Chinese patent CN03809879.2 firstly manufactures the midsole with the shoe welt, and then injects the sole connected with the midsole. Risk of hydrolysis, affecting product quality
And the integrated injection molding of the sole is not conducive to the diversification of the sole styles

Embodiment 1

[0053] See Figure 1-2 , The present invention discloses a shoe mold, which includes a shoe last 1, an upper mold 2 and a lower mold 3. Among them, the shoe last 1 is the mother body of the shoe, and is the shoe forming mold, and the shoe last 1 can be replaced with any shoe last 1 required for the shoe to be manufactured. In this embodiment, the shoe last 1 is provided with an upper 11. The lower mold 3 can move along the vertical direction to close and separate with the upper mold 2, and the upper mold 2 is provided with an injection hole for injecting liquid injection plastic.

[0054] The upper mold 2 includes a first half body 21 and a second half body 22. The first half body 21 and the second half body 22 are symmetrically arranged so that the first half body 21 and the second half body 22 can be combined with the lower body The mold 3 is matched, that is, the upper mold 2 is divided into two halves along the longitudinal middle plane. The first half body 21 and the second...

Embodiment 2

[0061] See Figure 3-6 In another embodiment provided by the present invention, the structure of the shoe mold in this embodiment is similar to that of the shoe mold in the first embodiment, and the similarities are not repeated here, and only the differences are introduced.

[0062] In this embodiment, it is specifically disclosed that the clamping portion 23 can abut the shoe welt 41. The arrangement of the clamping portion 23 enables the shoe edge strip 41 to abut the shoe upper 11 stably, avoiding a gap between the shoe edge strip 41 and the shoe upper 11, which causes the liquid injection plastic to overflow. The clamping portion 23 is provided with a first pressure surface 231 and a second pressure surface 232. The first pressure surface 231 can press the top surface 411 of the shoe welt 41, and the second pressure surface 232 can press the outer surface of the shoe welt 41. Side 412. Among them, the top surface 411 of the shoe edge 41 refers to the end surface of the shoe...

Embodiment 3

[0070] See Figure 7-Figure 8 The present invention provides a shoe sole. A shoe welt 41 is provided on the top of the shoe sole 4, wherein the shoe welt 41 can be integrally injection molded with the sole 4, or can be connected in other ways, which is not limited here. The sole 4 is bonded to the upper 11 through a shoe mold. The lower mold 3 of the shoe mold is provided with a cavity for placing the sole 4, and the upper mold 2 of the shoe mold is provided with a clamping portion 23 for clamping the shoe welt 41. When the upper mold 2 of the shoe mold is closed with the lower mold 3 mounted with the sole 4, the projection of the outer contour of the lower end of the upper 11 on the shoe last 1 in the direction of the lower mold 3 coincides with the inner contour of the shoe along the strip 41, and the shoe The top end of the rib 41 abuts on the upper 11.

[0071] In the sole 4 disclosed in the present invention, since the sole 4 is provided with a hanging edge 42, the hanging ...

Abstract

The invention discloses a shoe mold, a sole and a method for molding the sole on an upper. The shoe mold comprises a shoe tree, an upper mold and a lower mold; the upper is arranged on the shoe tree; the upper mold comprises a first half body and a second half body; the first half body and the second half body are arranged symmetrically and can move transversely to open or close the upper mold; a shoe welt is arranged at the top of the sole; a cavity is formed in the sole; a mold cavity for accommodating the sole is formed in the lower mold; a clamping part for clamping the shoe welt is arranged on the upper mold; when the upper mold and the lower mold with the sole accommodated in the mold cavity are combined, the projection of the outer contour of the lower end of the upper towards the lower mold is overlapped with the inner contour of the shoe welt, and the top end of the shoe welt abuts against the upper; and when a liquid injection molding material is poured into the cavity of the sole, the sole and the upper can be bonded integrally. Positioning and shaping of the shoe welt can be supported through the strength and the hardness of the sole with the prefabricated cavity, so that the embedding position of the sole cannot be deviated.

Description

Technical field [0001] The invention relates to the technical field of shoemaking, in particular to a shoe mold, a shoe sole and a method for molding the shoe sole to the shoe upper. Background technique [0002] Chinese patent CN03809879.2 discloses a method that can simultaneously mold the shoe welt and sole to the shoe upper. This method uses an annular shoe welt, the inner contour of which substantially corresponds to the outer contour of the lower part of the upper, and the lower part corresponds to the position of the shoe welt on the finished shoe. The shoe welt can be fixed to the edge of the thinner auxiliary sole before it is put into the shoe mold, and placed on the annular support surface of the top surface of the lower mold when the shoe mold is in the open position, or it can be placed with the help of adhesive or positioning pins. The auxiliary sole is connected to the bottom surface of the upper, and when the lower mold is moved to its closed position, the shoe w...
