Abstract
A molding process for shoes with inner lining comprises: placing a molding inner core sleeved with an inner lining in a combined external mold being preset with a semi-molded shell; performing a mold-closing action to make the semi-molded shell in the first external mold and the second external mold attach to the inner lining, respectively; and heating to vulcanize the semi-molded shell, and combining with the inner lining to produce a shoe with inner lining.
Claims8
A molding process for shoes with an inner lining, wherein the molding process is configured to realize the combined molding of a shoe shell and the inner lining, and the molding process comprises:
- providing a combined external mold comprising a first external mold and a second external mold;
- a molding inner core which is able to be placed in the combined external mold and cooperate for a mold-closing or mold-opening action, wherein the molding inner core is configured to be sleeved by the inner lining;
- a preset inner core which is able to be placed in the combined external mold and cooperate for the mold-closing or mold-opening action, wherein a first partition is provided on the preset inner core and extends in a circumferential direction along a part corresponding to an ankle;
- placing the preset inner core in the combined external mold and performing the mold-closing action, wherein a shell molding space is formed between the preset inner core and the combined external mold after the mold closing action, the shell molding space matches the shape of the shoe shell, the shell molding space is separated to form a separate space by the first partition after the mold closing action, and the separate space is configured to form a partial semi-molded shell;
- injecting a plasticizing material into the shell molding space to form the semi-molded shell adhered to inner walls of the first external mold and the second external mold;
- performing the mold-opening action to separate the semi-molded shell along a joint of the first external mold and the second external mold so as to form two parts that move with the first external mold and the second external mold, respectively;
- placing the molding inner core sleeved with the inner lining in the combined external mold being preset with the semi-molded shell;
- performing the mold-closing action to form a shoe body molding space between the molding inner core and the combined external mold, and make the semi-molded shell in the first external mold and the second external mold attach to the inner lining, respectively, wherein the shoe body molding space matches the combination shape of the shoe shell and the inner lining, and the inner lining has a part exposed to the partial semi-molded shell;
- and
- heating to vulcanize the semi-molded shell, and combining with the inner lining to produce a shoe with inner lining.
