Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bra product manufacturing, in particular to a mold cup shaping mold and a mold cup preparation method using the mold to shape and punch the mold cup. BACKGROUND

[0002] With the improvement of people's living standards, the wearing comfort of bras is increasingly demanding. The mold cup is an important part of the bra, and its quality directly affects the use of the final bra product.

[0003] The current mold cup production process is as follows: the cutting piece used to prepare the mold cup is placed in the shaping mold for hot pressing shaping. After hot pressing, the cutting piece has the required curvature and shape of the mold cup. At this time, the hot-pressed cutting piece is punched using a punching machine and a die to obtain one mold cup.

[0004] Since the mold cup is irregularly shaped and has a curvature, when the punching machine is used for punching in the current preparation process, the irregular edges connected to each other will be raised upwards, causing the die to be unable to completely punch down the mold cup, or the edges after punching are not flat, which does not achieve the desired effect, affecting the quality of the mold cup and the quality of the final product, and reducing the wearing comfort of the user.

After molding, the formed mold cup semi-finished product also has a tapered design, so that the tapered part does not upturn when the die cutter is punched, thereby ensuring the cutting quality.

[0013] Preferably, the width of the lower pressing strip is 5-15mm.

[0014] Preferably, the vertical height of the positioning frame is 0.5-5mm, so as to effectively block the die cutter.
