Abstract

The invention discloses a molding and foaming process for foaming shoe soles. A cavity for accommodating a base structure is provided in a lower mold, and a dissolving pool for carrying molten material is arranged on the base structure, and a shoe last is placed on the base of the base structure. Above, the upper mold and the lower mold are clamped, and the molten material is foamed in the airtight cavity composed of the upper mold, the last and the lower mold, and the finished shoe sole including the film structure is obtained; The film structure with the molten material pool makes the molten material pool on the film structure replace the original molten material pool on the lower mold, so that the height of the lower mold can be set as low as possible without being limited by the molten material pool , so as to reduce the clamping height of the upper mold and the lower mold, and finally lower the position of the clamping line formed on the finished shoe sole, avoiding the obvious sight of the naked eye, increasing the aesthetics of the finished shoe sole, and meeting the production requirements.

Description

technical field [0001] The invention relates to a manufacturing process for shoe soles, in particular to a molding and foaming process for foamed shoe soles. Background technique [0002] In the existing foam shoe sole forming foaming process, the foam shoe sole injects the molten material into the molten material pool of the lower mold, puts the shoe last into the lower mold, and then closes the upper mold and the lower mold to dissolve the material. Foaming is carried out in a closed cavity composed of upper mold, shoe last and lower mold to obtain the finished shoe sole, where the upper mold and lower mold are molded together, a mold line will be formed on the finished shoe sole; in order to ensure the foaming quality of the sole , the molten material pool of the lower mold must ensure a certain height to accommodate enough molten material for foaming, which will lead to the height of the lower mold also need to ensure a certain height, and the upper mold and the lower mo...
