Problems solved by technology

[0003] In the existing molding process, because the side molds are closed first, and then the shoe last mold is lowered, the excess rubber material is discharged from the mouth, which is easy to stain the upper fabric and affect the appearance of the finished shoe
Moreover, this production process cannot meet the requirements for the production of molded shoes with high sole rubber and parts above the inner sole rib, which limits the development scope of molded shoes and the variety of molded shoes.

Embodiment Construction

[0016] see figure 1 , the finished shoe molding process of the present invention, the steps are: the shoe last molds 17, 22 for molding are inverted and fixed on the lower workbench 10 of the molding equipment; the bottom mold 16 and the side mold 6 are installed on the upper part of the molding equipment ;Put the spare upper on the shoe last mold; place the filling material, film and accessories according to the shoemaking requirements and paste them on the upper; The side mold and the shoe last mold are pressed together, and the pressure is maintained for molding vulcanization treatment; the pressure is 9-11MPa, and after 8-15 minutes of vulcanization treatment, the side mold is opened, and the bottom mold rises and returns to its original position; finally, the shoe last is taken off , to complete the entire process of molding and pressing shoes.

[0017] In the above process, when entering the molding stage, the initial stage of molding is deflated once or several times a...

Abstract

A die pressing technology for manufacturing shoe includes reversely fixing the shoe last mould to lower bench, installing side mould and bottom mould to upper part of the press, sleeving shoe upper on said shoe last mould, adding filler, rubber sheet and auxiliary onto shoe upper, closing mould set, pressing while sulfuring for 8-15 min, opening the mould set, and separating finished shoe from shoe last. Its advantage is high shoe quality.

Description

technical field [0001] The invention relates to a shoe molding process and molding equipment. The shoe last mold is inverted in the invention to produce molded shoes. The equipment of the invention adopts hydraulic transmission and electric heating for molding. Background technique [0002] The existing shoe molding process refers to the process of vulcanizing the raw rubber sole and bonding it with the upper by means of molding equipment, thereby completing the process of combining the upper and the sole. Molded shoes have the characteristics of firmness, wear resistance, flex resistance, not easy to open glue, and strong water resistance, so they are widely used in the production of labor insurance shoes. At present, domestically-made shaping molding equipment is beam-type double-mode hydraulic molding equipment. The shoemaking process using this equipment is as follows: the shoe last mold for molding is fixed on the upper workbench of the molding equipment in the forward ...
