Description

Technical Field

[0001] The utility model belongs to the technical field of mold cup preparation, and particularly relates to a forming mold for a mold cup. Background Art

[0002] In the current underwear industry, basic mold cups typically utilize a sponge layer laminated with two layers of fabric (sponge cups) or two layers of sandwich fabric (sandwich cups). However, this manufacturing method presents a common problem: the edge of the mold cup (the rim) reveals the original color of the sponge or the internal structure of the sandwich material, which can lead to fraying or unraveling. This problem is particularly noticeable on products with bright colors or where a portion of the mold cup is exposed. Furthermore, fraying or unraveling can cause discomfort and pricking sensations on the skin; it also increases the defective rate of the mold cup, resulting in wasted resources and increased costs.

[0003] In order to solve this problem, a new method for preparing a mold cup is proposed, that is, by first preparing a mold cup precursor, which has two mold cup bodies, and then folding one of the mold cup bodies to the side of the other mold cup body so that the two mold cup bodies fit together, and finally molding again to obtain a clean-edge mold cup, and using the folded edge as the bowl mouth of the mold cup obtained after folding, which can effectively avoid the problem of the bowl mouth being wired or loose. In this process, the mold cup precursor also needs to be obtained by molding, but because the mold cup precursor obtained after molding needs to be folded, in order to ensure that the two mold cup bodies after folding can be perfectly aligned without wrinkles, the two mold cup bodies of the mold cup precursor obtained by molding are not exactly the same, and the curvature of the two mold cup bodies is different. It is impossible to obtain such a mold cup precursor by molding using existing traditional molds, so it is necessary to design a new mold to meet the structural requirements of the mold cup precursor.

DETAILED DESCRIPTION

[0025] In order to help those skilled in the art better understand the technical solutions of the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0026] Reference Figures 1 to 6The utility model provides a forming mold for a mold cup, which is used for molding to obtain a mold cup precursor for preparing a clean-edge mold cup, the mold cup precursor having a first mold cup body and a second mold cup body, the arch of the first mold cup body is different from the arch of the second mold cup body, and the size of the bowl circumference of the first mold cup body is equal to the size of the bowl circumference of the second mold cup body. Specifically, the forming mold in this embodiment includes a die 1, a punch 2, a first pressing plate 3 and a second pressing plate 4, wherein the die 1 has two symmetrically arranged inwardly concave spherical grooves 11, the punch 2 has a first spherical body 21 and a second spherical body 22 protruding toward the spherical grooves 11 and correspondingly forming the first mold cup body and the second mold cup body, the first spherical body 21 and the second spherical body 22 are respectively arranged opposite to one spherical groove 11 and cooperate with each other.

[0027] Furthermore, if Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, the first spherical body 21 includes a first side 211, a second side 212 and a third side 213 connected end to end in sequence, the second spherical body 22 includes a fourth side 221, a fifth side 222 and a sixth side 223 connected end to end in sequence, the third side 213 is connected to the sixth side 223, a side of the first spherical body 21 close to the second spherical body 22 is the third side 213, and a side of the second spherical body 22 close to the first spherical body 21 is the sixth side 223, the third side 213 is connected (overlaps) with the sixth side 223, and both are used to form a folding edge when the mold cup precursor is folded after molding, that is, the mold cup precursor obtained after molding is folded along the sides formed corresponding to the third side 213 and the sixth side 223, so that the bowl mouth of the final net-edge mold cup is the side corresponding to the third side 213 and the sixth side 223. In addition, the length of the first side 211 is equal to the length of the third side 213 , the length of the second side 212 is equal to the length of the fourth side 221 , and the length of the third side 213 is equal to the length of the sixth side 223 .

[0028] In the mold cup precursor obtained after molding the fabric using the mold in this embodiment, the first mold cup body formed by the first spherical body 21 is used as the cup surface layer of the clean-edge mold cup after folding, and the second mold cup body formed by the second spherical body 22 is used as the cup lining layer of the clean-edge mold cup after folding.

[0029] The punch 2 also includes an extension portion 23, one end of which is connected to the first side 211, the second side 212, the fourth side 221 and the fifth side 222 at the same time. The height direction of the extension portion 23 is perpendicular to the length direction of the first pressing plate 3. The extension portion 23 is provided to facilitate the adjustment of the stretching depth during molding according to the elasticity of the fabric and the shaping effect after molding, so as to ensure a better molding effect after molding.

[0030] Specifically, the curvature of the first spherical body 21 of the punch 2 is greater than that of the second spherical body 22. The vertical distance from the BP point of the first spherical body 21 to the side of the extension 23 adjacent to the first and second spherical bodies 21 and 22 is greater than the vertical distance from the BP point of the second spherical body 22 to the side of the extension 23 adjacent to the first and second spherical bodies 21 and 22. Furthermore, the orthographic projection of the first spherical body 21 on the side of the extension 23 adjacent to the first and second spherical bodies 21 and 22 is symmetrical with the orthographic projection of the second spherical body 22 on the side of the extension 23 adjacent to the first and second spherical bodies 21 and 22 about the third side 213 and / or the sixth side 223. This arrangement ensures that after the mold cup precursor is folded along the sides corresponding to the third and sixth sides 213 and 223, the first and second mold cup bodies can be better fitted together, avoiding misalignment, bulges, wrinkles, and other incomplete fits when the two are fitted together.

In addition, the contour shape of the first through hole 31 is the same as the contour shape of the extension portion 23, and the orthographic projection of the extension portion 23 on the first pressing plate 3 is located within the range of the first through hole 31. The extension portion 23 can also pass through the first through hole 31. The center of the extension portion 23 and the center of the first through hole 31 are located in the same vertical direction. When the extension portion 23 is located in the first through hole 31, the distance between the outer wall of the extension portion 23 and the inner wall of the first through hole 31 is 1 to 10 mm.

[0032] The second pressing plate 4 is provided with a second through hole 41 running through the thickness direction thereof, and the second through hole 41 is used for the die 1 to pass through. When the distance between the inner wall of the first through hole 31 of the first pressing plate 3 and the outer wall of the extension portion 23 is large, the second pressing plate 4 is required to perform auxiliary pressing between the die 1 and the punch 2 during molding to ensure that the die 1 and the punch 2 can fit tightly together, thereby ensuring the molding effect of the fabric.

[0033] The mold cup obtained by using the forming mold of the utility model can be used as a mold cup precursor for making a clean-edge mold cup, and it is ensured that after the mold cup precursor is folded, the two mold cup bodies can fit together perfectly to form a complete mold cup, avoiding wrinkles or misalignment.
