Description

Technical Field

[0001] This utility model belongs to the field of manufacturing technology of integral cloth cups, specifically relating to a molding die for a reference cup. Background Technology

[0002] In existing technology, one-piece fabric cups are formed by bonding two layers of fabric together with an adhesive film in the middle. If nipple covers are to be added in the middle, they are pre-bonded flat between the two layers of fabric, then molded and shaped on a specific bullet-shaped mold. After being heated and shaped in the mold, they are then marked and cut into the desired cup shape. If auxiliary parts such as shaping pads, underwires, or silicone are to be added, the molding process cannot be well controlled. Utility Model Content

[0003] In view of this, in order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a molding die for a reference cup.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This utility model provides a molding die for a reference cup, including a first die and a second die. The first die is used to prepare a pre-formed part, and the second die is used to mold the pre-formed part to obtain the reference cup. The first die includes a first pressure plate and a second pressure plate arranged opposite to each other. The second die includes a concave die, a convex die, and a flat plate located between the concave die and the convex die. The concave die has an inwardly recessed spherical groove, and the convex die has a spherical body protruding toward the spherical groove and correspondingly forming the reference cup. The spherical groove and the spherical body are arranged opposite to each other and cooperate with each other. The flat plate has a through hole extending through its thickness direction, and the through hole is used for the spherical body to pass through the flat plate and insert into the spherical groove.

[0006] According to a preferred embodiment of this utility model, the second pressure plate is located above the first pressure plate. The first pressure plate has a first receiving groove and two second receiving grooves on its side near the second pressure plate, with the first receiving groove located below the two second receiving grooves. The second pressure plate of this utility model is a flat plate. When molding using the first mold, after the soft support, nipple cover, outer fabric, and inner fabric are placed on the first pressure plate according to their positions, the second pressure plate is finally placed on top and pressed tightly. This ensures the bonding strength between the soft support and nipple cover and the outer and inner fabrics in the resulting pre-formed part, preventing the pre-formed part from becoming loose. Furthermore, pre-pressing the soft support, nipple cover, outer fabric, and inner fabric using the first mold in advance, making them a single unit, ensures that the components will not shift or misalign during molding using the second mold, which is beneficial for controlling the final forming condition of the reference cup.

[0007] According to a preferred embodiment of the present invention, the pre-formed component includes an outer fabric, an inner fabric, nipple covers, and a soft support. The first receiving groove is used to receive the soft support, and both second receiving grooves are used to receive the nipple covers. The shape and size of the first receiving groove match the shape and size of the soft support, and the shape and size of the second receiving groove match the shape and size of the nipple covers.

[0008] According to a preferred embodiment of the present invention, the depth of each of the second receiving grooves gradually decreases from its center outwards, and the centers of the two second receiving grooves are located on the same straight line parallel to the length direction of the first pressure plate.

[0009] According to a preferred embodiment of the present invention, the middle part of the first receiving groove extends along a line parallel to the width direction of the first pressure plate and passes through the midpoint of the line connecting the centers of the two second receiving grooves.

[0010] According to a preferred embodiment of the present invention, the die further includes a peripheral portion disposed outside the spherical groove.

[0011] According to a preferred embodiment of the present invention, the spherical groove includes two spherical groove bodies, a first connecting portion for connecting the two spherical groove bodies, and a second connecting portion located on the side of each spherical groove body away from the first connecting portion. The side of each second connecting portion away from the spherical groove body, the bottom edge of each spherical groove body, and the bottom edge of the first connecting portion are together fixedly connected to the inner edge of the outer periphery.

[0012] According to a preferred embodiment of the present invention, a soft support groove is formed on the outer periphery from the side closest to the punch to the other side. The soft support groove is located at the inner edge of the outer periphery and is set corresponding to the bottom edge of the spherical groove body and the bottom edge of the first connecting part. When the preform is molded using the second mold, the soft support in the preform is placed at the position of the soft support groove on the outer periphery.

[0013] According to a preferred embodiment of the present invention, the spherical body includes two spherical bodies and a third connecting portion for connecting the two spherical bodies, wherein the spherical bodies and the spherical groove bodies are arranged in a one-to-one correspondence, and the third connecting portion is arranged in a corresponding manner to the first connecting portion.

[0014] Specifically, in some embodiments of this utility model, by setting an outer periphery in the concave mold, a first connecting part for connecting two spherical groove bodies, a second connecting part located on the side of each spherical groove body away from the first connecting part, and a soft support groove on the outer periphery, and setting a third connecting part on the punch corresponding to the first connecting part, the reference cup obtained after molding with the second mold has an outer periphery area corresponding to the outer periphery, a first connecting area corresponding to the first connecting part and the third connecting part, and a second connecting area corresponding to the second connecting part. Such a reference cup has better compatibility, and different cup shapes can be designed based on it. Furthermore, by trimming the outer periphery, the undercut and side profile can be directly formed without the need for additional manufacturing processes to prepare the side profile and undercut, which helps to simplify the process.

[0015] According to a preferred embodiment of the present invention, the orthographic projection of the sphere on the horizontal plane completely coincides with the orthographic projection of the spherical groove body and the first connecting portion on the horizontal plane.

[0016] Due to the adoption of the above technical solutions, the advantages of this utility model compared with the prior art are as follows: The molding mold for a reference cup of this utility model is obtained by designing a first mold and a second mold, first using the first mold to mold a pre-shaped part, and then using the second mold to mold the pre-shaped part as a whole to obtain a reference cup. Such a reference cup has auxiliary components such as nipple covers and soft supports, which can play a good role in preventing nipple protrusion and supporting the breast. It can well control the molding effect of the reference cup, and the obtained reference cup can be directly used to make one-piece fabric cups of different cup shapes or styles, with wide applicability.

Detailed Implementation

[0024] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0025] Reference Figures 1 to 4 This utility model provides a molding die for a reference cup, including a first die and a second die. The first die is used to prepare a pre-formed part, and the second die is used to mold the pre-formed part to obtain the reference cup.

[0026] Furthermore, the first mold includes a first pressure plate 1 and a second pressure plate arranged opposite to each other, with the second pressure plate located above the first pressure plate 1 and being a flat plate 4. In addition, the pre-formed part includes an outer fabric, an inner fabric, and nipple covers and a soft support located between the outer fabric and the inner fabric. The pre-formed part can be obtained by pressing the soft support and nipple covers between the outer fabric and the inner fabric using the first mold.

[0027] Specifically, such as Figure 1As shown, the first pressure plate 1 has a first receiving groove 11 for accommodating the soft tray and two second receiving grooves 12 for accommodating the nipple covers on the side near the second pressure plate. The first receiving groove 11 is located below the two second receiving grooves 12. The shape and size of the first receiving groove 11 match the shape and size of the soft tray, and the shape and size of the second receiving grooves 12 match the shape and size of the nipple covers. The outer fabric and the inner fabric have the same shape and size, and the area of ​​the outer fabric is greater than or equal to the area of ​​the first pressure plate 1 and the second pressure plate. The depth of each second receiving groove 12 gradually decreases from its center to the periphery, ensuring that the nipple covers in the pre-formed part are three-dimensional when molded using the first mold. The centers of the two second receiving grooves 12 are located on the same straight line parallel to the length direction of the first pressure plate 1. The middle part of the first receiving groove 11 extends along the width direction parallel to the first pressure plate 1 and passes through the midpoint of the line connecting the centers of the two second receiving grooves 12, ensuring that the positions of each component are accurate and misalignment does not occur when molded using the first mold.

[0028] Furthermore, such as Figures 2 to 4 As shown, the second mold includes a concave mold 2, a convex mold 3, and a flat plate 4 located between the concave mold 2 and the convex mold 3. The concave mold 2 has an inwardly recessed spherical groove 21, and the convex mold 3 has a spherical body 31 protruding towards the spherical groove 21 and correspondingly forming a reference cup. The spherical groove 21 and the spherical body 31 are arranged opposite to each other and cooperate with each other. A through hole 41 is provided on the flat plate 4, which extends through its thickness direction. The through hole 41 is used for the spherical body 31 to pass through the flat plate 4 and be inserted into the spherical groove 21, and the center of the through hole 41 coincides with the center of the pressure plate. In addition, the center of the through hole 41, the center of the concave mold 2, and the center of the convex mold 3 are all located in the same vertical direction.

[0029] Specifically, the die 2 also includes a peripheral portion 22, which is disposed outside the spherical groove 21. The spherical groove 21 includes two spherical groove bodies 211, a first connecting portion 212 for connecting the two spherical groove bodies 211, and a second connecting portion 213 located on the side of each spherical groove body 211 away from the first connecting portion 212. The side of each second connecting portion 213 away from the spherical groove body 211, the bottom edge of each spherical groove body 211, and the bottom edge of the first connecting portion 212 are fixedly connected to the inner edge of the peripheral portion 22. The shape of the inner edge of the outer periphery 22 corresponding to the bottom edge of the spherical groove body 211 and the bottom edge of the first connecting part 212 is adapted to the shape of the bowl of the reference cup. Furthermore, the outer periphery 22 has a soft support groove 221 at this position from the side closest to the punch 3 to the other side. The shape and size of the soft support groove 221 are adapted to the shape and size of the soft support. The setting of the soft support groove 221 can further strengthen the bonding force between the soft support and the outer and inner fabrics in the preform, which is beneficial to integral molding.

[0030] The spherical body 31 in the punch 3 includes two spherical bodies 311 and a third connecting portion 312 for connecting the two spherical bodies 311. The spherical bodies 311 are correspondingly arranged with the spherical groove bodies 211, and the third connecting portion 312 is correspondingly arranged with the first connecting portion 212. Furthermore, the orthographic projection of the spherical body 31 on the horizontal plane completely coincides with the orthographic projection of the spherical groove bodies 211 and the first connecting portion 212 on the horizontal plane. During molding, the spherical groove bodies 211 in the die 2 and the spherical bodies 311 in the punch 3 cooperate with each other to press and form the cup body of the reference cup.

[0031] The method of using the molding die in this utility model is as follows:

[0032] First, lay the outer fabric flat on the first pressure plate 1, ensuring that the center is aligned. Then, place the soft support and nipple cover on the outer fabric at the positions corresponding to the first receiving groove 11 and the second receiving groove 12 on the first pressure plate 1, respectively. Finally, lay an inner fabric flat on top of the soft support and nipple cover. Finally, press the second pressure plate on the inner fabric and mold it at a temperature of 180-185°C for 100-150 seconds to obtain the predetermined part.

[0033] Next, place the pre-formed part on the cavity mold 2, and ensure that the soft support in the pre-formed part is placed in the soft support groove 221 on the outer periphery 22 of the cavity mold 2. Then place the plate 4 on the pre-formed part and adjust the position of each part so that the center of the cavity mold 2, the pre-formed part and the plate 4 are all located in the same vertical direction. Finally, put in the punch 3 and mold it at a temperature of 185 to 190°C for 150 to 180 seconds to obtain the reference cup.
