Abstract
A production process of an insole, the steps of: cleaning an insole mold; spraying an oily release agent into a cavity of an upper mold and a cavity of a lower mold of the mold; uniformly fixing cloth in the cavity of the upper mold; injecting shoe material into the cavity of the lower mold of the mold, covering the upper mold of the mold to lock the upper mold and the lower mold after finishing injecting shoe material, and then placing the mold in an oven for baking, opening the upper mold of the mold after finishing baking, and taking out the insole. The production process of an insole is simple in process and high in yield rate, and uses the characteristics that the cloth and the raw material have good adhesion to directly put the cloth into the mold to take shape, thereby eliminating a glue adhesion process.
Claims9
A production process of an insole, comprising the steps of:
- (1) cleaning an insole mold;
- (2) spraying an oily release agent into a cavity of an upper mold and a cavity of a lower mold of the mold;
- (3) uniformly fixing cloth in the upper mold;
- (4) injecting shoe material into the cavity of the lower mold of the mold, covering the upper mold of the mold and locking the upper mold and the lower mold after finishing injecting shoe material, and then placing the mold in an oven for baking to emulsify and foam the shoe material, opening the upper mold of the mold after finishing foaming, and taking out the insole;
- wherein the shoe material comprises material A and material B;
- wherein the material A further comprises raw material in parts by weight:
- 68-72 parts of castor oil, 23-26 parts of polyethylene glycol ether, 1.2-1.6 parts of solid acid catalyst, 0.9-1.0 parts of tertiary amine catalyst, 0.03-0.05 parts of gel catalyst, 0.8-1.2 parts of foam stabilizer, 1.3-1.6 parts of vinyl silicone oil, 1-1.2 parts of ammonia catalyst and 0.4-0.6 parts of water;
- and
- wherein the material B further comprises the following raw material in parts by weight:
- 68-72 parts of diphenylmethane diisocyanate, 22-26 parts of polyether, and 4-8 parts of diargonized carbon.
