Abstract

The invention relates to a process for die-pressing and shaping a cup and a die. The die comprises a cup die-pressing upper die capable of heating, a cup die-pressing lower die capable of heating, a cold shaping die and a cyclic water supply device, wherein the upper end face of the cup die-pressing lower die is concavely provided with concave parts with the same shapes as two bra cups; the lowerend face of the cup die-pressing upper die is convexly provided with convex parts matched with the concave parts on the upper end face of the cup die-pressing lower die in shapes; the cup die-pressing upper die and the cup die-pressing lower die are in contact connection; the lower end face of the cold shaping die is convexly provided with cold shaping convex parts matched with the concave parts on the upper end face of the cup die-pressing lower die in shapes; and the cold shaping die and the cyclic water supply device are fixedly connected by inserting. The process for die-pressing and shaping the cup comprises the steps of low-temperature die-pressing and shaping and cooling, reinforcing and shaping. After the low-temperature die-pressing, the heated fiber cotton cup is subjected to cold shaping and reinforcing by using the cold shaping die. The cup subjected to the equipment treatment has the characteristics of portability, good air permeability, yellowing avoidance and strong moisture absorption during wearing.

Description

technical field [0001] The invention relates to a molding process and a mold, in particular to a molding process and a mold for shaping cups. Background technique [0002] For a long time, the cups of ordinary bras have been made of high-temperature foam molding. The molding equipment consists of a heatable cup molding upper mold and a cup molding lower mold. The upper end of the cup molding lower mold is concave. For the same concave part, the lower end surface of the cup molding upper mold is convexly provided with a convex part matching the shape of the upper end surface concave part of the cup molding lower mold, so that the concave part and the convex part cooperate to mold a foam cup; the foam high temperature molding process is: Heat the cup molding upper mold and the cup molding lower mold to 190°C-200°C, put foam between the cup molding upper mold and the cup molding lower mold, the time for the upper and lower molds to cooperate with the molding is 170 seconds -190...
