A heating device and heating method for a variable temperature mold

Abstract

The invention discloses a heating device and method of a variable-temperature mold. The heating device of the variable-temperature mold is suitable for a modern three-dimensional type mold cup which is insufficient in forming camber and softness. Optimization design is conducted on the variable-temperature mold, according to fact that a non-woven fabric has the advantage of being good in air permeability, on the basis of heating of an original electrical heating bar, the heating mode capable of controlling hot air is adopted, the hot air can enter the variable-temperature mold, by means of the advantage of the permeability of the fabric, heat is uniformly transmitted to everywhere inside the non-woven fabric, and it is guaranteed that in the hot pressure molding process, the variable-temperature mold can be placed in the constant temperature. By means of the heating method, the heating time can be effectively shortened, the production cost can be effectively lowered, the work efficiency is improved, problems brought by the fact that the hot pressure molding temperature is too high and too low are avoided, the molding effect and quality of the mold cup can be well improved and raised, and the molding technology is perfected.

Description

technical field [0001] The invention relates to the technical manufacturing field of bra mold cups, in particular to a heating device and a heating method for a variable temperature mold for making bra mold cups. Background technique [0002] 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, the market share of molded cup bras has continued to expand since it was launched. [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 mold cup bra is made of sponge, spray glue or silk floss, which is shaped by high temperature and high pressure. Its shape is round and natural, firm and plump. Among them, the non-woven fabric mold cup has a smoother appearance after hot molding, without any sewing stitches. The most important thing is that it h...

Problems solved by technology

[0006] In view of the spatial dimension of the mold cup in the hot molding process is a curve change, and the temperature is a non-linear change and the shortcomings of the traditional hot molding equipment, which causes the thermal efficiency of the upper and lower aluminum molds to decrease and the heating is uneven during the mold closing process. , it is necessary to design a new variable temperature mold heating device to realize the constant temperature of the non-woven material during the molding heating process, so as to avoid the problems caused by the hot molding temperature being too high or too low, improve and improve The molding effect and quality of the mold cup, reduce production costs, improve production efficiency, and improve the molding process of the mold cup
