Description

Technical Field

[0001] This utility model belongs to the field of mold technology for cup forming molds, specifically relating to a forming mold for an integral cloth cup. Background Technology

[0002] Existing one-piece fabric cups consist of two layers of fabric plus an insert or pad in the middle. Moreover, the outer fabric and the insert (pad) are not bonded together, making the insert or pad loose between the two layers of fabric rather than a whole. This results in poor shaping effect, poor shape and fit, and obvious separation after washing.

[0003] To address the aforementioned issues, the cotton core can be sandwiched between two layers of fabric with an adhesive film, and then molded using a mold to achieve high-temperature one-time molding, resulting in a one-piece fabric cup. However, because the cotton core shrinks at high temperatures, existing molds cannot guarantee that the cotton core will still adhere well to the fabric layers after high-temperature molding, resulting in excessive dimensional differences. Consequently, the molded fabric cup has only two layers of fabric adhering around its perimeter, leading to poor uniformity around the cup. Utility Model Content

[0004] 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 one-piece cloth cup.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A molding die for a one-piece fabric cup includes a shaving core layer and fabric layers located on both sides of the shaving core layer. One side of the fabric layer is bonded to one side of the shaving core layer. The molding die includes a first die assembly and a second die assembly. The first die assembly is used to mold the shaving core layer to obtain the shaving core layer. The second die assembly is used to mold the shaving core layer with the fabric layers bonded to it to obtain the one-piece fabric cup. The first die assembly includes a first concave die and a first convex die. The second die assembly includes a second concave die and a second convex die. The first concave die has an inwardly recessed groove, the contour of the top surface of which matches the outer edge of the second concave die and / or the second convex die. The first die assembly is used to mold the shaving core layer. Based on the indentation produced after molding, the shaving core layer is cut or trimmed to obtain a precisely sized shaving core layer that can fit the fabric layers. The first die assembly does not require high temperature during molding. The second die assembly is used to mold the fabric layers with adhesive film bonded to them and the shaving core layer obtained after molding by the first die assembly in one step under high temperature conditions to obtain the one-piece fabric cup.

[0007] According to the preferred embodiment of the utility model, the first concave die comprises a concave die body and a first flat plate fixedly connected with the outer edge of the bottom surface of the concave die body, the bottom surface of the concave die body is flush with the bottom surface of the first flat plate, the concave die body is provided with the groove on the bottom surface thereof upwards, and the shape of the groove is the same as that of the concave die body; the first convex die comprises a convex die body and a second flat plate fixedly connected with the outer edge of the bottom surface of the convex die body, the bottom surface of the convex die body is flush with the bottom surface of the second flat plate, and the first flat plate is parallel to the second flat plate.

[0008] According to the preferred embodiment of the utility model, the concave die body comprises a first annular connecting portion between the top and the bottom thereof, and the first annular connecting portion is inclinedly arranged downwards and outwards from the side thereof away from the first flat plate; the outer surface of the convex die body comprises an annular surface for connecting the top surface and the bottom surface of the convex die body, and the annular surface is inclinedly arranged downwards and outwards from the side thereof away from the second flat plate.

[0009] According to the preferred embodiment of the utility model, the acute angle included angle formed between the first annular connecting portion and the first flat plate is greater than the acute angle included angle formed between the annular surface and the second flat plate. This is because the thickness of the cut cotton core is 2-4 mm, and such arrangement leaves sufficient space for the cut cotton core when being molded between the first concave die and the first convex die, otherwise, the first concave die and the first convex die cannot cooperate after the cut cotton core is put in.

[0010] According to the preferred embodiment of the utility model, the first annular connecting portion comprises a first section and a second section and two third sections oppositely arranged, the first section and the second section are located in the middle of the first annular connecting portion, the first section is used for connecting one end of the two third sections on the same side, and the second section is used for connecting the other end of the two third sections on the same side.

[0011] According to the preferred embodiment of the utility model, the second convex die has a second annular connecting portion, two spherical bodies protruding towards the second concave die and a first connecting section for connecting the two spherical bodies, the first connecting section and the two spherical bodies are located inside the second annular connecting portion, and the inner edge of the second annular connecting portion is fixedly connected with the outer edges of the two spherical bodies and the two ends of the first connecting section.

[0013] Preferably, by respectively setting the first die assembly and the second die assembly, the cut cotton core is first compressed and cut by the first die assembly to obtain a cut cotton core layer with accurate size, and by setting the first annular connecting part, a certain width is reserved around the cut cotton core layer to bear the change caused by shrinkage, and is matched with the second annular connecting part of the second convex die, so that after the cut cotton core layer compressed by the first die assembly is high-temperature molded with the fabric layer with adhesive film by the second die assembly, the one-step forming can be realized, thereby reducing the process and saving time, and meanwhile, the molded cloth cup is integrated, the cut cotton core layer and the fabric layer can be completely attached, the uniformity around the cloth cup is good, and the forming effect is good.

[0014] According to the preferred embodiment of the utility model, the width of the first section is 2-3mm wider than the width of the fourth section, the width of the second section is 2-3mm wider than the width of the fourth section, the width of the third section is 3-5mm wider than the width of the sixth section, and the width of the first connecting section is 12-15mm. Such setting is equivalent to reserving a larger width around the cut cotton core layer in advance, and the size change caused by shrinkage of the cut cotton core has been considered in advance, so that the cut cotton core layer molded by the first die assembly can be well attached to the two fabric layers after high-temperature molding by the second die assembly, and the size difference between the cut cotton core layer and the two fabric layers caused by shrinkage can be reduced.

[0015] According to the preferred embodiment of the utility model, the second annular connecting part is upwardly and outwardly inclinedly arranged from the side close to the spherical body.

[0016] According to the preferred embodiment of the utility model, the orthographic projection of the concave die body on the horizontal plane is located in the range of the first flat plate, the orthographic projection of the convex die body on the horizontal plane is located in the range of the second flat plate, and the orthographic projection of the concave die body on the horizontal plane coincides with the orthographic projection of the convex die body on the horizontal plane.

[0017] According to the preferred embodiment of the utility model, the thickness of the concave die body is greater than the thickness of the first flat plate, the thickness of the convex die body is greater than the thickness of the second flat plate, and the thickness of the concave die body is greater than the thickness of the convex die body.

DETAILED DESCRIPTION

[0030] In order to make the technical personnel of the technical field better understand the technical scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor should belong to the scope of protection of the present application.

[0031] With reference to Figures 1 to 8 The present application provides a forming die for a connected cloth cup. The connected cloth cup obtained by die pressing comprises a shaved wool core layer and fabric layers located on both sides of the shaved wool core layer. One side of the fabric layer is bonded to one side of the shaved wool core layer and completely adheres thereto. The connected cloth cup obtained after die pressing is integrated. The forming die in the embodiment comprises a first die assembly 10 and a second die assembly 20. The first die assembly 10 is used for die pressing the shaved wool core. The shaved wool core layer with precise dimensions that can cooperate with the fabric layer is obtained by shearing or cutting according to the indentation generated after die pressing. The second die assembly 20 is used for high-temperature die pressing the shaved wool core layer with the fabric layer bonded thereto to obtain the connected cloth cup. The first die assembly 10 comprises a first female die 1 and a first male die 2 that cooperate with each other. The first female die 1 is located above the first male die 2. The second die assembly 20 comprises a second female die 3 and a second male die 4 that cooperate with each other. The second male die 4 is located above the second female die 3.

[0032] Further, as Figures 1 to 5As shown, the first die 1 in the first mold assembly 10 includes a die body 11 and a first plate 12 fixedly connected to the outer edge of the bottom surface of the die body 11. The first punch 2 in the first mold assembly 10 includes a punch body 21 and a second plate 22 fixedly connected to the outer edge of the bottom surface of the punch body 21. The first plate 12 is parallel to the second plate 22. The bottom surface of the die body 11 is flush with the bottom surface of the first plate 12, and the bottom surface of the punch body 21 is flush with the bottom surface of the second plate 22. The die body 11 is located in the middle of the first plate 12, and the punch body 21 is located in the middle of the second plate 22. The center of the die body 11 and the center of the punch body 21 are located in the same vertical direction. Furthermore, the orthographic projection of the die body 11 on the horizontal plane is within the range of the first plate 12, and the orthographic projection of the punch body 21 on the horizontal plane is within the range of the second plate 22. The orthographic projections of the die body 11 and the punch body 21 on the horizontal plane coincide.

[0033] Specifically, the thickness of the die body 11 is greater than the thickness of the first plate 12, the thickness of the punch body 21 is greater than the thickness of the second plate 22, and the thickness of the die body 11 is greater than the thickness of the punch body 21. The die body 11 has a groove 111 formed on its bottom surface to accommodate the punch body 21. The shape of the groove 111 is the same as the shape of the die body 11. The height of the groove 111 is less than the thickness of the die body 11 but greater than the thickness of the punch body 21. The area of ​​the top surface of the groove 111 is greater than the area of ​​the top surface of the punch body 21. This ensures that when the first mold assembly 10 is used for pressing, the punch body 21 of the first punch 2 can completely enter the groove 111 of the first die 1 and cooperate with the first die 1 to effectively mold the cotton core.

[0034] like Figures 1 to 4 As shown, the die body 11 of the first die 1 includes a first annular connecting portion located between its top and bottom. A groove 111 is formed between the inner wall of the first annular connecting portion and the inner wall of the top of the die body 11. The first annular connecting portion is used to connect the top and bottom of the die body 11, and the first annular connecting portion is inclined downward and outward from the side away from the first flat plate 12. Correspondingly, the outer surface of the punch body 21 of the first punch 2 includes an annular surface 211, which is used to connect the top and bottom surfaces of the punch body 21. The annular surface 211 is inclined downward and outward from the side away from the second flat plate 22, and the first annular connecting portion is correspondingly provided with the annular surface 211. Figure 2As shown, the acute angle between the first annular connecting portion and the first flat plate 12 is greater than the acute angle between the annular surface 211 and the second flat plate 22. Such arrangement allows sufficient space for accommodating the cut tobacco core when the cut tobacco core is molded between the first concave mold 1 and the first convex mold 2, while ensuring that the convex mold body 21 and the groove 111 in the concave mold body 11 can match each other, which is beneficial to obtaining a cut tobacco core layer with good size and shape.

[0035] Further, as shown, Figures 6 to 8 The second concave mold 3 of the second mold assembly 20 has two inwardly recessed spherical grooves 31, and the second convex mold 4 of the second mold assembly 20 has a second annular connecting portion, two spherical bodies 42 protruding towards the spherical grooves 31 and corresponding to the formation of the cloth cup, and a first connecting segment 43 for connecting the two spherical bodies 42. The first connecting segment 43 and the two spherical bodies 42 are located inside the second annular connecting portion, and the inner edge of the second annular connecting portion is fixedly connected with the outer edges of the two spherical bodies 42 and the two ends of the first connecting segment 43. The second concave mold 3 is provided with a second connecting segment 32 corresponding to the first connecting segment 43 of the second convex mold 4, and the second connecting segment 32 is located between the two spherical grooves 31. The shape and size of the first connecting segment 43 and the second connecting segment 32 are the same, and the width of the first connecting segment 43 and the second connecting segment 32 is 12-15 mm. In addition, the profile of the top surface of the groove 111 in the concave mold body 11 is consistent with the outer edge of the second annular connecting portion and the outer edge of the top surface of the second concave mold 3, which ensures that the cut tobacco core layer molded by the first mold assembly 10 can have good matching degree with the second mold assembly 20.

[0036] Specifically, the first annular connecting portion of the concave mold body 11 in the embodiment includes a first segment 112 and a second segment 113 oppositely arranged and two third segments 114 oppositely arranged. The first segment 112 and the second segment 113 are located in the middle part of the first annular connecting portion, the first segment 112 is used to connect one end of the two third segments 114 on the same side, and the second segment 113 is used to connect the other end of the two third segments 114 on the same side. The second annular connecting portion is upwardly and outwardly inclined from the side close to the spherical body 42, and includes a fourth segment 411 and a fifth segment 412 oppositely arranged and two sixth segments 413 oppositely arranged. The fourth segment 411 and the fifth segment 412 are respectively arranged corresponding to the first segment 112 and the second segment 113, and the sixth segment 413 is arranged corresponding to the third segment 114. The fourth segment 411 and the fifth segment 412 are located in the middle part of the second annular connecting portion, the fourth segment 411 is used to connect one end of the two sixth segments 413 on the same side, and the fifth segment 412 is used to connect the other end of the two sixth segments 413 on the same side.

[0037] Since the cut core shrinks at high temperature, considering the size change after shrinkage, the width of the first section 112 is 2-3mm wider than that of the fourth section 411, the width of the second section 113 is 2-3mm wider than that of the fourth section 411, and the width of the third section 114 is 3-5mm wider than that of the sixth section 413. Such setting is equivalent to reserving a larger width around the cut core layer in advance, which is used to bear the size change caused by shrinkage, so as to ensure that the cut core layer after being molded by the first mold assembly 10 will not have too large size difference with the two fabric layers after being molded by the second mold assembly 20 at high temperature, so as to ensure that the cut core layer can be better attached to the fabric layer.

[0038] The first mold assembly 10 is used to mold the cut core, and the size-accurate cut core layer that can be matched with the fabric layer is obtained by shearing or cutting according to the indentation after molding. Then, the two fabric layers with adhesive film are respectively bonded to the two sides of the cut core layer, and the second mold assembly 20 is used to mold the cut core layer and the fabric layer as a whole under high temperature conditions, so that the integrated connected fabric cup is obtained after one-time forming, the manufacturing process of the connected fabric cup is effectively reduced, the manufacturing time is saved, and the cut core layer and the fabric layer are completely attached, and the forming effect of the connected fabric cup is good.

[0039] The above embodiments are only for illustrating the technical concept and characteristics of the utility model, and the purpose is to enable those skilled in the art to understand the content of the utility model and implement it, and cannot limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit and essence of the utility model shall be covered within the protection scope of the utility model.
