Problems solved by technology

But its shortcoming is, the insole that this method makes, after the insole is placed on the sole surface, when the people walks on the insole, the insole is easy to slide due to the transformation of the sole of the foot, which makes walking very inconvenient and uncomfortable. Therefore, the method still needs to be improved

Abstract

The invention relates to a manufacturing method of a polyurethane inner sole and is characterized in that the manufacturing method comprises the following steps in sequence: materials are prepared: a component a and a component b are prepared and are respectively placed; a polyurethane film which meets the requirement is laid on the inner surface of a lower die body (22); an upper die body (21) is covered; an aspirating hole is used for vacuumizing so as to lead the polyurethane film to be adhered on the corresponding inner surface of the lower die body (22); the component a and the component b are mixed; the mixed mixture is injected into a die by a die filling port (24) till the mixture appears at a flash gate (25) of a die (2) and then stands for 2 to 30 minutes; and a polyurethane inner sole (1) with rough edges is taken out for carrying out trimming so as to obtain a finished product. The method has the advantages that the polyurethane surface of the back surface of the inner sole is a non-film surface; and the inner sole can be adhered with the bottom surface of shoes when in use, thus eliminating the problem that the change of the origin of force of the sole of a foot can cause the sliding of the inner sole easily when people walk.

Description

technical field [0001] The invention relates to a method for making polyurethane insoles. Background technique [0002] Existing a kind of application number is that CN200510008635.7 name is called " manufacture method of breathable insole " Chinese invention patent has proposed a kind of manufacture method of insole, and this method injects a foaming material in a mold cavity of a bottom mould, and then a The first top mold closes the mold cavity and heats it to trigger the foaming material to bridge and foam in the mold cavity to form a polyurethane / polyurethane body, and then the polyurethane / polyurethane body is not yet cooled. Next, open the first top mold, and then utilize a second top mold to close the mold cavity, so that a fiber material and an adhesive material arranged on the second top mold are put into the mold cavity together, and the second top mold is controlled. The mold is heated at a temperature not lower than the melting temperature of the adhesive mater...
