Problems solved by technology

[0002] The traditional shoe making method is to put the upper on the shoe last after sewing, and then paste the sole, dry and shape the finished shoe to make the finished shoe. This manufacturing method requires a large number of shoe lasts and a long production line, and the labor cost is high; In view of the above problems, there is currently a method of injection molding the sole and the upper to make shoes, but the upper and the sole are made of the same material that can be injection molded, and cannot be adapted to the leather or fabric upper that is sewn.

Embodiment Construction

[0024] refer to figure 1 with figure 2 As shown, a rubber sole injection mold includes an upper mold 3, a middle mold 2, and a lower mold 1 that can be closed sequentially. The upper mold 3, the middle mold 2, and the lower mold 1 are all roughly rectangular, and the mold is rectangular after mold closing body.

[0025] The lower mold 1 is provided with a shoe last 11 that can be fitted with a shoe upper 41. The shoe last 11 is supported in the lower mold 1 by two columns 12. The middle mold 2 is formed with a shoe upper peripheral tightening hole 21 that penetrates up and down. The upper mold 3 is formed with a shoe sole. The molding groove 31 and the injection hole 32 connected to the molding groove 31 of the sole, when the mold is closed, the hole 21 around the shoe upper and the shoe last 11 tighten the shoe upper 41, and the middle mold 2, the shoe last 11, the shoe upper and the shoe sole are formed The groove 31 surrounds a closed shoe sole mold cavity, and the perip...

Abstract

The invention provides a rubber sole injection mold and an injection molding method. The injection mold comprises an upper mold body, a middle mold body and a lower mold body which are sequentially combined. A shoe tree capable of being sleeved with an upper is arranged on the lower mold body. An up-down-through upper peripheral banding hole is formed in the middle mold body. A sole forming groove and injection holes communicating with the sole forming groove are formed in the upper mold body. During mold combination, the upper periphery is banded by the upper peripheral banding hole and the shoe tree, a closed sole mold cavity is defined by the middle mold body, the shoe tree, the upper periphery and the sole forming groove, one-time injection combination of the rubber sole and the sewed upper can be achieved by means of the rubber sole injection mold, and the fit step of the rubber sole and the upper is omitted, so that the labor cost is saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a rubber sole injection mold and an injection molding method. Background technique [0002] The traditional shoe manufacturing method is to put the upper on the shoe last after sewing, then paste the sole, dry and shape the finished shoe to make the finished shoe. This manufacturing method requires a large number of shoe lasts and a long production line, and the labor cost is high; In view of the above problems, at present there is a method for making shoes by injection molding the sole and the upper at one time, but the upper and the sole are the same material that can be injection molded, and cannot adapt to the leather or fabric upper that is sewn. Contents of the invention [0003] The object of the present invention is to address the deficiencies of the prior art, and provide a rubber sole injection mold and an injection molding method in which soles and uppers are combined by one injection. [0004] The purpose of the ...
