[0002] With the increasing requirements for environmental protection, more and more women begin to pay attention to healthy underwear products. At present, traditional mold cups all use sponge and polyurethane foam as underwear mold cups. These products have toxic foaming agents remaining inside the mold cups, which affect the health of the breasts and the human body. In addition, traditional mold cups are made using traditional foaming agents as foaming materials. Since these materials are all hydrophilic materials, water molecules remain inside the mold cups for a long time, resulting in mildew and bacterial growth. At present, the silicone foam effect of the current silicone foam mold cups is not good, and they are prone to brittle fracture, causing the underwear to break and become unusable. Moreover, the current silicone foam mold cups have patches attached to the outer surface of the mold cups, reducing the skin-friendly feeling. Summary of the Utility Model

The convex mold is fixedly arranged on the upper surface of the upper base. Uniformly arranged round nails are provided on the upper surface of the convex mold, and the positions or the protruding lengths of the round nails can be adjusted according to the size of the underwear mold. The limit blocks are fixedly arranged at the four corners and the middle positions of the front and rear ends on the upper surface of the upper base, and the guard strip is arranged to surround the convex mold. The lower mold includes a lower base, a concave mold, a limit groove and a guard strip. The concave mold is fixedly arranged on the upper surface of the lower base. Uniformly arranged round nails are provided on the upper surface of the concave mold. The limit grooves are arranged at the four corners and the middle positions of the front and rear ends on the upper surface of the upper base, and the guard strip is arranged to surround the concave mold. The convex mold and the concave mold are matched in terms of size and shape.

[0006] Further, the round nails arranged on the upper surfaces of the convex mold and the concave mold are symmetrically arranged to match each other, and the lengths of the round nails depend on the position of the cloth or mesh cloth in the middle or offset position of the foamed silicone mold cup.

[0007] Further, the limit blocks arranged on the upper base and the limit grooves arranged on the lower base have the same size and match each other in position, and the limit blocks and the limit grooves at the middle position of the rear end are provided with mold type identifiers.
