Integrated shoe moulding technology

Abstract

The invention provides an integrated shoe moulding technology. The integrated shoe moulding technology comprises the following steps: through an injection moulding mode, a lower cold mold blank, a middle cold mold blank, and an upper cold mold blank which are mutually matched are obtained, a secondary forming die is produced, the secondary forming die is arranged on a secondary forming machine, the lower cold mold blank is put in a mold cavity, the middle cold mold blank is put on the upper surface of the lower cold mold blank, the upper cold mold blank is fixed on a fixed part of the upper cold mold blank, mold locking of the secondary forming die is controlled through the secondary forming machine, and the steps of heating and mold opening on the secondary forming die are carried out by the secondary forming machine. According to the invention, through a secondary moulding mode, the lower cold mold blank, the middle cold mold blank, and the upper cold mold blank are fused and connected as one body, connection of the lower cold mold blank and the upper cold mold blank is firm, a glue or suture is not required, so that body health of the workers and the users cannot be influenced.

Description

technical field [0001] The invention relates to a production process of shoes, in particular to a molding process of one-piece shoes. Background technique [0002] In the manufacturing process of traditional shoes, the joint between the upper and the sole needs to be glued and heat-set, otherwise it is difficult to firmly connect the upper to the sole. Then, the glue used to bond the upper and the sole is usually toxic, and the workers are inevitably affected by the toxicity of the glue during the production process, and after the shoes are used for a long time, the toxicity of the glue will also slow down. Slowly volatilized, affecting the health of workers and users. [0003] In order to solve the above problems, some shoes are directly fixed with seams at the joint between the upper and the sole without glue. The stitches used to connect the upper and the sole of these shoes will inevitably be exposed, which will affect the appearance of the shoe. , and after the shoes ...

Problems solved by technology

Then, the glue used to bond the upper and the sole is usually toxic, and workers are inevitably affected by the toxicity of the glue during the production process, and the toxicity of the glue in the shoes will also slow down after a long period of use. Slowly volatilized, affecting the health of workers and users

[0003] In order to solve the above problems, some shoes are directly fixed with seams at the joint between the upper and the sole without glue. The stitches used to connect the upper and the sole of these shoes will inevitably be exposed, which will affect the appearance of the shoe. , and after the shoes are used for a long time, the sutures are easy to wear or even fall off, which will cause the shoes to crack and affect the service life of the boots
