Technical Field

[0001] The utility model belongs to the technical field of preparation of bra cup molds, and in particular relates to a molding mold suitable for a bra cup with a three-dimensional nipple cover. Background Art

[0002] With the improvement of social technology, women have higher and higher requirements for the functions of bras, especially for thin-cup bras. They hope that the bra cups can be thin and light while preventing bulges.

[0003] In the prior art, a nipple cover is placed between two layers of fabric to reduce the thickness of the mold cup while ensuring the effect of preventing convex spots. However, during molding, the mold currently used does not overlap the upper and lower fabrics at the edges, that is, it is not well positioned and limited. During pressing, the fabrics will move, causing the nipple cover to shift. When the nipple cover shifts, the left and right sides of the mold cup are no longer symmetrical, and the mold cup obtained after molding will become a defective product. Utility Model Content

[0004] In view of this, in order to overcome the defects of the prior art, the purpose of the utility model is to provide a molding mold suitable for a bra cup with a three-dimensional nipple cover, which can avoid the movement of the fabric during molding, thereby reducing the displacement of the nipple cover.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A forming mold suitable for a bra cup with a three-dimensional nipple cover, comprising a concave mold and a convex mold, wherein the concave mold has a spherical groove concave inwardly, and the convex mold has a spherical body protruding toward the spherical groove and corresponding to the cup, the spherical groove and the spherical body are arranged opposite to each other and cooperate with each other, the forming mold also includes a pressing plate located between the concave mold and the convex mold, the convex mold includes a first annular connecting part and a connecting frame, the first annular connecting part is used to connect the spherical body and the connecting frame; the concave mold includes a base, a second annular connecting part and the spherical groove are arranged on the base, the second annular connecting part is arranged corresponding to the first annular connecting part, and the orthographic projection of the first annular connecting part on the second annular connecting part partially overlaps with the second annular connecting part.

[0007] Through the mutual cooperation of the first annular connecting part on the male mold and the second annular connecting part on the female mold, as well as the auxiliary pressing action of the pressing plate, a part of the width of the double-layer fabric is molded together on all sides to ensure that the fabric cannot move, thereby reducing the displacement of the nipple cover between the double-layer fabric.

[0008] According to a preferred implementation aspect of the utility model, the pressing plate is provided with a through hole penetrating through the thickness direction thereof, and the through hole is used for the spherical body to pass through the pressing plate and then be inserted into the spherical groove.

[0009] According to a preferred implementation aspect of the utility model, the inner periphery of the first annular connecting portion is fixedly connected to the outer edge of a side of the spherical body away from the die, and the outer periphery of the first annular connecting portion is fixedly connected to the inner wall of a side of the connecting frame close to the die; the side of the spherical body away from the die is flush with a side of the first annular connecting portion close to the die and a side of the connecting frame close to the die.

[0010] According to a preferred implementation aspect of the present invention, the center of the spherical body and the centers of the first annular connecting portion and the connecting frame are located in the same vertical direction.

[0011] According to a preferred implementation aspect of the utility model, a side surface of the second annular connecting portion close to the punch is flush with a side surface of the base close to the punch, an inner periphery of the second annular connecting portion is fixedly connected to an outer edge of a side surface of the spherical groove close to the punch, and an outer edge of a side surface of the second annular connecting portion close to the punch coincides with an outer edge of a side surface of the base close to the punch.

Such a setting can ensure that the spherical body of the male mold can pass through the pressing plate and enter the spherical groove in the female mold during molding, so that the spherical body and the spherical groove cooperate with each other. When the spherical body is completely accommodated in the spherical groove, the depth of the connecting frame is set to be greater than the thickness of the pressing plate, so that the male mold can be easily removed from the through hole.

[0014] According to a preferred embodiment of the present invention, the shape of the connection frame is the same as that of the through hole, and the outer wall of the connection frame fits the inner wall of the pressure plate during molding. When the spherical body is completely accommodated in the spherical groove during molding, the connection frame is also partially accommodated in the through hole, and the top of the connection frame is located outside the through hole, which facilitates the removal of the punch from the through hole.

[0024] In order to enable those skilled in the art to better understand the technical solution 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 solution in the embodiments of the present invention. Obviously, the described embodiments 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 creative work should fall within the scope of protection of the present invention.

[0025] Reference Figures 1 to 4 The utility model provides a molding die for a bra cup with a three-dimensional nipple cover, comprising a male die 1, a female die 2 and a pressing plate 3 located between the female die 2 and the male die 1, the female die 2 having an inwardly recessed spherical groove 22, the male die 1 having a spherical body 11 protruding toward the spherical groove 22 and correspondingly forming a cup, the spherical groove 22 and the spherical body 11 being arranged opposite to each other and cooperating with each other.

[0026] Furthermore, if Figure 1 and Figure 3 As shown, the male mold 1 further includes a first annular connection portion 12 and a connection frame 13. The first annular connection portion 12 is used to connect the spherical body 11 and the connection frame 13. The center of the spherical body 11 and the centers of the first annular connection portion 12 and the connection frame 13 are located in the same vertical direction. Specifically, the inner periphery of the first annular connection portion 12 is fixedly connected to the outer edge of the side of the spherical body 11 away from the female mold 2, the outer periphery of the first annular connection portion 12 is fixedly connected to the inner wall of the side of the connection frame 13 close to the female mold 2, and the side of the spherical body 11 away from the female mold 2 is flush with the side of the first annular connection portion 12 close to the female mold 2 and the side of the connection frame 13 close to the female mold 2.

[0027] Furthermore, if Figure 2 and Figure 3As shown, the die 2 includes a base 21, on which a second annular connection portion 23 and a spherical groove 22 are provided, and the center of the spherical groove 22 is located in the same vertical direction as the center of the second annular connection portion 23 and the base 21. The second annular connection portion 23 is provided corresponding to the first annular connection portion 12 on the punch 1, and the orthographic projection of the first annular connection portion 12 on the second annular connection portion 23 partially overlaps with the second annular connection portion 23. The distance between the inner periphery and the outer periphery of the first annular connection portion 12 is smaller than the distance between the inner periphery and the outer periphery of the second annular connection portion 23. In this embodiment, the distance between the inner periphery and the outer periphery of the first annular connection portion 12 is set to 5 to 7 mm, and the distance between the inner periphery and the outer periphery of the second annular connection portion 23 is set to 15 to 18 mm. During molding, when the spherical body 11 is completely accommodated in the spherical groove 22, the first annular connecting portion 12 of the male mold 1 is pressed against the surface of the second annular connecting portion 23 of the female mold 2. The mutually pressed portions between the two can ensure that the fabric molded between the female mold 2 and the male mold 1 has mutually fitted portions, and the fit is good, thereby preventing the fabric from shifting after molding. In addition, the distance between the inner periphery and the outer periphery of the second annular connecting portion 23 is larger, which also facilitates the placement of the pressing plate 3 on the surface of the base 21 during molding.

[0028] Specifically, the side surface of the second annular connection portion 23 close to the punch 1 is flush with the side surface of the base 21 close to the punch 1, the inner periphery of the second annular connection portion 23 is fixedly connected to the outer edge of the spherical groove 22 close to the punch 1, and the outer edge of the side surface of the second annular connection portion 23 close to the punch 1 coincides with the outer edge of the side surface of the base 21 close to the punch 1.

[0029] Further, such as Figure 3 As shown, the pressing plate 3 is provided with a through hole 31 that runs through the thickness direction thereof, and the shape of the connecting frame 13 is the same as that of the through hole 31. The through hole 31 is used for the spherical body 11 on the punch 1 to pass through the pressing plate 3 and then be inserted into the spherical groove 22, and can also accommodate part of the connecting frame 13 of the punch 1. In this embodiment, the center of the through hole 31 coincides with the center of the pressing plate 3, and the length of the through hole 31 is less than the length of the pressing plate 3, and the width of the through hole 31 is less than the length of the pressing plate 3.

[0030] In order to ensure the positioning accuracy during molding, the center of the through hole 31 is located in the same vertical direction as the center of the concave mold 2 and the center of the punch 1. The thickness of the pressing plate 3 is also set to be smaller than the depth of the spherical body 11 and the connecting frame 13, the length of the through hole 31 is greater than the length of the spherical groove 22, and the width of the through hole 31 is greater than the width of the spherical groove 22. The size of the through hole 31 also matches the size of the connecting frame 13 to ensure that the outer wall of the connecting frame 13 fits the inner wall of the pressing plate 3 during molding. Figure 4 At the same time, the top of the connecting frame 13 is located outside the through hole 31, which facilitates the removal of the punch 1 from the through hole 31.

[0031] The preparation process of a bra cup with a three-dimensional nipple cover in the utility model is as follows:

[0032] First, two layers of fabric are cut into the required size, and a film is coated on one of the fabrics. Then, the two nipple covers are placed on the side of the fabric coated with the film using a positioning plate and the positions of the nipple covers are determined. Then, another piece of fabric is covered on the side where the nipple covers are located. After that, the fabric is placed on a flat mold for shaping, so that the film initially bonds the two layers of fabric and the nipple covers together to obtain a composite fabric. The size of the composite fabric is larger than the size of the through hole 31 on the pressing plate 3.

[0033] The composite fabric is placed on the concave mold 2 of the above-mentioned molding die, and then the pressing plate 3 is placed on the composite fabric, and the positions of each part are adjusted so that the centers of the concave mold 2, the composite fabric and the pressing plate 3 are all located in the same vertical direction, and finally the convex mold 1 is placed for high-temperature molding. During molding, the part where the first annular connecting part 12 and the second annular connecting part 23 fit together can ensure that the upper and lower layers of fabric are firmly pressed together to prevent the fabric from shifting.

[0034] After the mold is finalized, it can be placed on a customized light film box for stippling according to the shape required by the design, and then cut along the stippling lines by machine to finally get the cup of the target style.

[0035] The mold cup obtained by using the molding mold of the utility model can be used as a basic mother mold, and other cloth cups of any shape can be obtained by performing shape design, stippling and cutting on the basis of the basic mother mold.

[0036] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
