Underwear cup molding die and underwear molding method thereof

Abstract

The invention discloses an underwear cup molding die. Cavities are formed in upper and lower dies, and superheated airflow is introduced into the cavities for heating, so that the die is rapidly preheated in a short time. The cavities are separated into multiple areas for respectively performing heating treatment at different temperatures, the condition that the temperature on the surface of the die is consistent with the temperature needed at each part of a mold pressing material is ensured, the heating effect of the cup material is improved, the problem caused by extremely high or low temperature is solved, the quality of the mold cup is improved, and the mold cup molding process is effectively perfected and improved. The molding die is suitable for molding modern three-dimensional cups of which the lower sides are thick and the upper sides are thin, so that the mold pressing temperature distribution on the die surface is reasonable, only the hot airflow is introduced into the first area of the lower die during mold pressing, so that the heating can be performed, the power consumption is reduced, the time is saved, the working efficiency is improved, the mold cup quality is improved, and the mold cup molding process is effectively perfected and improved.

Description

technical field [0001] The invention belongs to the technical field of manufacturing underwear cups, and in particular relates to a molding die for underwear cups and a molding method thereof. Background technique [0002] Now there are many types of bras on the market. According to the production process of bras, they can be divided into padded bras, molded cup bras and single-layer bras. Among them, molded cup bras have continuously expanded their market share since they were launched. Whether it is a large company, such as Triumph, Maniform, Aimer, Embry Form, etc., and other second-tier brands of small and medium-sized enterprises are all developing and producing molded cup bras. [0003] The characteristic of the molded cup bra is that the cup can be thick or thin, and it can be formed at one time through the molding process. The cup part of the molded cup bra is usually made of polyurethane soft foam or 3D cotton, which is shaped by high temperature and high pressure....

AI Technical Summary

Problems solved by technology

If the temperature is low, the hand feels rough, the cotton cup is thicker overall, the volume of the bowl becomes smaller, the shape of the extruded cotton cup is not obvious, and the original sponge state still exists; if the temperature is high, the resulting cotton cup feels too smooth and stiff. There is no elasticity, there will be wrinkles when folded, and it is not easy to restore. The whole cotton cup is thinner, the volume of the cup becomes larger, and the color of the cloth turns yellow; if the temperature is too high, the cloth will be burnt, and the mold will be stained with burnt Cloth, cannot continue to use

[0005] When preheating the upper and lower molds of the traditional underwear cup hot molding machine, since the mold is a solid structure, it takes a long time to reach the predetermined temperature during preheating. At the same time, the upper and lower molds must be continuously powered on and heated during molding. Relatively high; and due to the irregular shape of the mold, the surface temperature distribution of the upper and lower molds is unreasonable, and it is difficult to ensure a suitable molding temperature
