Stereo molding device of shell fabric

Abstract

The invention relates to a stereo molding device of a shell fabric, which comprises an upper mold with an upper mold cavity and a lower mold with a lower mold cavity, wherein the lower part of the upper mold is provided with a first arc face; the upper part of the upper mold is provided with a second arc face; when the upper mold and the lower mold are compounded, the first arc face is tightly clung to the second arc face; a bullet mold capable of moving in the vertical direction is arranged in the upper mold cavity; a gridding tray capable of moving in the vertical direction is arranged in the lower mold cavity; a heating device is arranged on the bullet mold; and a hot air blowing device is arranged on the gridding tray. Due to a stereo fixing way for the shell fabric, which is adopted by the device, and is combined with the bullet mold and different heat-conducting ways of the upper mold and the lower mold, the tension degree of each edge of cut sheets of the shell fabric, which is generated through the punching of the molds, is relatively balanced, and the problems of serious damage to the performance of components of the shell fabric, and damage and fold of precise cut sheets are solved. The device is wide in application range and is suitable for molding any elastic shell fabric or shell fabric without elasticity.

Description

technical field [0001] The invention relates to a molding device used in the underwear molding industry, in particular to a three-dimensional molding device for face cloth. Background technique [0002] At present, the technologies commonly used in the underwear face cloth molding industry mainly include two types: ordinary mold molding technology and precision cut bullet mold molding technology, both of which belong to the category of "plane molding". Precisely cut pieces are fixed on a flat plate, and are shaped by heat conduction and pressure through a high-temperature mold. Both types of technologies have their own inherent defects. The ordinary mold molding technology adopts high temperature and sufficient shaping method, which seriously damages the stretching and tissue damage of the fabric, which greatly reduces the wearability of the fabric; the precision cutting bullet molding technology adopts The local shaping method has relatively small stretching and tissue dam...

AI Technical Summary

Problems solved by technology

Both types of technologies have their own inherent defects. The ordinary mold molding technology adopts high temperature and sufficient shaping method, which seriously damages the stretching and tissue damage of the fabric, which greatly reduces the wearability of the fabric; the precision cutting bullet molding technology adopts The local shaping method has relatively small stretching and tissue damage for high-elastic fabrics, but for ordinary elastic or inelastic fabrics, the area for fixing is relatively small, and because the "plane molding method" is still used, cutting The unbalanced tensile force caused by the punching of each part of the die, combined with the general or no elasticity of the material, can easily cause the fixed parts of the cut to be pulled off during the molding process, or appear damaged or wrinkled.
