Description

Technical Field

[0001] The utility model relates to the technical field of handbag processing, in particular to a forming die for a handbag. Background Art

[0002] The design of a tote bag must balance load-bearing strength with ease of folding. To ensure the bag can withstand a certain amount of weight and pressure, connecting hems are usually provided between the bottom and sides to increase structural stability. These hems play a key structural support role, preventing the bag from deforming or breaking under pressure.

[0003] The connecting fold is usually connected to the bottom surface of the handbag. During the molding process, the base material is squeezed and bent by the mold. The base material at the bottom of the mold constitutes the bottom surface of the handbag, and the base material at both sides of the mold constitutes the side surfaces of the handbag. The side surfaces on both sides form connecting surfaces relative to each other in the width direction. The opposite connecting surfaces are bent toward each other and connected to form the bag body. The connecting fold needs to be folded inward and attached to the side wall of the mold before the connecting surface is bent, so that it is adhered to the inner surface of the connecting surface when it is bent, thereby achieving the effect of strengthening the connection strength between the bottom and the side surfaces.

[0004] In existing handbag forming devices, a bottom insert is typically used to compress the connecting fold, causing it to fold inward. To ensure that the connecting fold connects to the inner surface of the connecting surface, the bottom insert must be withdrawn before the connecting surface folds. However, after the bottom insert is withdrawn, the elastic potential energy accumulated in the connecting fold during the extrusion process can cause it to recover due to inertia, expanding back to its original position. This can prevent the connecting fold from connecting to the inner surface of the connecting surface, affecting the handbag's yield rate. Utility Model Content

[0005] The purpose of the utility model is to solve the technical problem in the prior art that, during the forming process of the handbag, the connecting fold may be redeployed to its original position after the bottom insert plate is withdrawn, resulting in the connecting fold being unable to connect with the inner surface of the connecting surface, thereby affecting the yield of the handbag.

[0006] In order to solve the above technical problems, an embodiment of the present utility model discloses a forming mold for a handbag, wherein the base material for forming the handbag includes a bottom surface and side surfaces located on both sides of the bottom surface along the length direction of the base material, and the side surfaces on both sides form connecting surfaces relative to each other on both sides of the width direction of the base material.

[0007] This molding die is in the shape of a rectangular parallelepiped as a whole, wherein the bottom contour of the molding die is adapted to the bottom contour of the base material, and the two side walls of the molding die opposite to each other in the length direction are adapted to the side shapes of the two sides of the base material; and the bottom of the molding die is adapted to press the bottom surface of the base material, and the side surfaces on both sides of the base material are bent and fitted to the corresponding side walls of the molding die, and the side surfaces and bottom surface of the two sides of the base material constitute shaped structure and surrounds the forming mold.

[0008] In addition, bottom folding edges are formed on both side edges of the bottom surface in the width direction, and folding adsorption parts are formed on the side walls on both sides in the width direction at positions corresponding to the bottom folding edges.

[0009] With the above technical solution, the overall shape of the forming mold is a rectangular parallelepiped, and the bottom contour of the forming mold is adapted to the bottom contour of the base material. When the forming mold is driven by the driving structure to press the bottom surface of the base material, the base material can bend from the crease between the bottom surface and the side surface, thereby forming shaped structure, further, the bottom insert plate located at the lower side of the forming mold can press the bottom folded edge located along the width direction of the base material, so that the bottom folded edge can be bent toward the side wall of the forming mold, and the folded edge adsorption portion on the side wall of the forming mold can adsorb the bottom folded edge to prevent the bottom folded edge from recovering under the action of inertia after the bottom insert plate is withdrawn, and then the side insert structure located beside the forming mold presses the connecting surface, so that the connecting surfaces relative to each other are bent toward the side wall of the forming mold, and the outer surface of the bottom folded edge is connected to the inner surface of the connecting surface, and at the same time, the connecting surfaces relative to each other on the side surfaces on both sides are connected, and the base material is surrounded to form a three-dimensional structure of a handbag with a rectangular cavity.

[0010] This forming mold prevents the bent bottom fold from re-expanding to its original position after the bottom insert is withdrawn by providing a folding edge adsorption portion on the side wall, ensuring that the outer surface of the bottom fold can be connected to the inner surface of the connecting surface, thereby improving the yield of the handbag.

[0011] An embodiment of the present utility model also discloses a forming mold for a handbag, wherein the folding adsorption portion includes a plurality of folding adsorption holes formed on the side wall of the forming mold. When viewed along the width direction, the contour of the area where the plurality of folding adsorption holes are located is adapted to the outer contour of the bottom fold.

[0012] By adopting the above technical solution, the multiple folding edge adsorption holes formed on the side wall of the forming mold can adsorb the bottom fold from the outer surface of the side wall toward the inner surface of the bottom fold when the bottom fold is attached to the side wall of the forming mold, so as to prevent the bottom fold from falling back, and the contour of the area where the multiple folding edge adsorption holes are located is adapted to the outer contour of the bottom fold, ensuring that the entire bottom fold is adsorbed and attached to the outer surface of the side wall, and the adsorption force generated by the multiple folding edge adsorption holes will not act on other structures, avoiding the generation of adsorption force on the connecting surface of the base material.

[0013] The embodiment of the present utility model further discloses a forming mold for a handbag, wherein the folding adsorption portion further comprises a plurality of auxiliary adsorption holes which are arranged on the side wall of the forming mold, are located in the area where the plurality of folding adsorption holes are located and are evenly distributed.

[0014] The diameter of the hem adsorption hole is larger than or equal to the diameter of the auxiliary adsorption hole, and the diameter of the hem adsorption hole and the diameter of the auxiliary adsorption hole are within the range of 0.1 mm to 0.25 mm.

[0015] By adopting the above technical solution, multiple auxiliary adsorption holes are located in the area where the multiple folding adsorption holes are located and are evenly distributed, which improves the adsorption force on the bottom folding and ensures that the entire bottom folding can be flatly attached to the outer surface of the side wall.

[0016] Moreover, the aperture of the folded edge adsorption hole and the aperture of the auxiliary adsorption hole are in the range of 0.1mm to 0.25mm, which can ensure that the adsorption hole can adsorb the bottom folded edge well. If the aperture of the folded edge adsorption hole and the aperture of the auxiliary adsorption hole are larger than the above range, the bottom folded edge may be adsorbed and deformed, and cannot be well connected with the inner surface of the connecting surface. If the aperture of the folded edge adsorption hole and the aperture of the auxiliary adsorption hole are smaller than the above range, the folded edge adsorption hole and the auxiliary adsorption hole are easily blocked by fine impurities during use, thereby losing the adsorption function.

[0017] The embodiment of the present utility model further discloses a forming mold for a handbag, which includes a mold body and forming side walls detachably connected to both sides of the mold body in the width direction, and a plurality of folding adsorption holes are provided on the forming side walls.

[0018] Using the above technical solution, the molding mold is composed of a mold body and a molding side wall. According to different shapes and specifications, the molding side wall can be disassembled and replaced with a molding side wall that is compatible with the pre-produced handbags to adapt to the production of different handbags. The multiple folding adsorption holes arranged on the molding side wall ensure that when producing handbags of different specifications, the bottom folding can be adsorbed during the production process.

[0019] An embodiment of the present utility model also discloses a forming mold for a handbag, wherein an air suction channel extending along the height direction of the mold body and an adsorption cavity connected to the air suction channel are formed between the forming side wall and the mold body, one end of the air suction channel is connected to an external air pump, and the other end is connected to the adsorption cavity.

[0020] In addition, a plurality of folded edge adsorption holes penetrate the molded side wall and communicate with the adsorption cavity.

[0021] The above technical solution forms an air intake channel between the forming sidewall and the mold body, extending along the height of the mold body. This channel guides the flow of gas and allows for the introduction of external gas. Connected to the air intake channel is an adsorption chamber, which generates adsorption force when gas is withdrawn. This draws air outward through the multiple hem adsorption holes, ultimately adsorbing the bottom hem. This structure cleverly arranges the air intake channel and adsorption chamber between the forming sidewall and the mold body, allowing the multiple adsorption holes to generate adsorption force without occupying space next to the mold, ensuring that the base material adheres to the outer surface of the mold.

[0022] An embodiment of the present utility model also discloses a forming mold for a handbag, in which an air suction channel and an adsorption chamber are both opened on the inner surface of the forming side wall close to the mold body, the air suction channel extends along the height direction of the mold body, and the adsorption chamber is arranged in the width direction in the area where multiple folded edge adsorption holes are located; and, a through hole penetrating the forming side wall is provided at one end of the air suction channel away from the adsorption chamber, which is connected to an external air pump through the through hole, and the other end is connected to the adsorption chamber.

[0023] Alternatively, the suction channel and the adsorption chamber are both opened on the end face of the mold body close to the forming side wall, the suction channel extends along the height direction of the mold body, and the adsorption chamber is arranged in the width direction in the area where the multiple folded edge adsorption holes are located; and, the molding side wall and the suction channel are away from one end of the adsorption chamber. A through hole is provided, and the suction channel is connected to an external air pump through the through hole, and the other end of the suction channel is connected to the adsorption chamber.

[0024] In addition, a sealing member surrounding the adsorption channel and the outer edge of the adsorption cavity is provided between the molding side wall and the mold body.

[0025] By adopting the above technical solution, when the air suction channel and the adsorption cavity are opened on the forming side wall of the forming mold, the forming side wall has a simple structure and is easy to process, thereby reducing the difficulty of the manufacturing process.

[0026] When the suction channel and the adsorption cavity are opened on the end surface of the mold body close to the molding side wall, since the molding side wall does not need to have redundant structures, the thickness of the molding side wall can be reduced, thereby reducing the weight of the molding side wall and facilitating disassembly and assembly.

[0027] In addition, a seal is arranged between the molding side wall and the mold body, surrounding the outer edge of the adsorption channel and the adsorption cavity, ensuring the sealing inside the adsorption cavity and the suction channel, preventing gas leakage, and thus maintaining a stable adsorption force.

[0028] An embodiment of the present utility model also discloses a forming mold for a handbag, wherein each forming side wall includes a side wall body, wherein a plurality of side adsorption holes are formed on the side surface in the length direction and are arranged at intervals along the height direction of the forming mold, and the side adsorption holes are connected to the suction channel or adsorption cavity from the outer wall of the side wall body.

[0029] By adopting the above technical solution, a plurality of side adsorption holes are arranged at intervals along the height direction on the side of the side wall body, which can be adsorbed by the plurality of side adsorption holes when the side of the base material is bent along the folding edge, ensuring that the side surfaces on both sides and the bottom surface are formed. Shape structure.

[0030] An embodiment of the present utility model also discloses a forming mold for a handbag, wherein each forming side wall further includes side wall flanges extending from both side edges of the side wall body in the length direction, the side wall body is opposite to the corresponding side walls of the forming mold in the width direction, the two side wall flanges extend toward the forming mold, surround the corresponding side walls of the forming mold, and the outer walls of the side wall flanges in the length direction are flush with the edges of the side wall body.

[0031] By adopting the above technical solution, the side wall flanges extending from the two side edges of the side wall body cooperate with the multiple side adsorption holes, so that the bent side of the base material can be flatly attached to the outer wall of the side wall flange, ensuring that the base material can be bent into Shape structure.

[0032] The embodiment of the present utility model further discloses a forming mold for a handbag, wherein a bottom adsorption piece is further provided at the bottom of the mold body, and an end edge of the bottom adsorption piece is flush with the bottom end surface of the mold body.

[0033] By adopting the above technical solution, the bottom adsorption part arranged at the bottom of the mold body can adsorb the base material, ensuring that the molding mold and the base material accurately enter the molding space for molding operations. Compared with the mold structure with a bottom support structure in the prior art, this molding mold has a light structure, a small number of parts, does not require more space, and reduces the difficulty of assembly production and subsequent maintenance operations.

[0034] The embodiment of the present utility model further discloses a forming mold for a handbag, wherein the base material is formed of at least one of paper, polyethylene (PE), and low-density polyethylene.

[0035] By adopting the above technical solution, the base material formed by at least one of paper, polyethylene (PE), and low-density polyethylene is airtight, ensuring that it can be adsorbed during the forming process, thereby maintaining a predetermined folding state.

[0036] The beneficial effects of the utility model are:

[0037] The utility model discloses a forming mold for a handbag, wherein the base material for forming the handbag includes a bottom surface and side surfaces located on both sides of the bottom surface along the length direction of the base material, wherein the side surfaces on both sides form mutually opposing connecting surfaces on both sides of the width direction of the base material. The forming mold is generally in the shape of a rectangular parallelepiped, wherein the bottom contour of the forming mold is adapted to the bottom contour shape of the base material, and the two side walls of the forming mold facing each other in the length direction are adapted to the side surfaces of the base material. In addition, the bottom of the forming mold is adapted to press the bottom surface of the base material, and the side surfaces on both sides of the base material are bent and adhered to the corresponding side walls of the forming mold. In addition, bottom folds are formed on both side edges of the bottom surface along the width direction, and fold suction portions are formed on the side walls of the forming mold at positions corresponding to the bottom folds. The fold suction portions provided on the side walls of the forming mold prevent the bent bottom folds from re-expanding to their original position after the bottom insert is withdrawn, ensuring that the outer surface of the bottom fold can connect with the inner surface of the connecting surface, thereby improving the yield rate of the handbag.

[0038] Specifically, the hem suction portion includes a plurality of hem suction holes formed on the sidewall of the forming mold.

[0054] In existing handbag forming devices, a bottom insert is typically used to compress the connecting fold, causing it to fold inward. To ensure that the connecting fold connects to the inner surface of the connecting surface, the bottom insert must be withdrawn before the connecting surface folds. However, after the bottom insert is withdrawn, the elastic potential energy accumulated in the connecting fold during the extrusion process can cause it to recover due to inertia, expanding back to its original position. This can prevent the connecting fold from connecting to the inner surface of the connecting surface, affecting the handbag's yield rate.

[0055] To this end, the utility model provides a forming mold for a handbag. The forming mold is in the shape of a rectangular parallelepiped, which is compatible with the basic shape of the handbag. The bottom contour of the forming mold completely matches the bottom surface contour of the base material, ensuring that the bottom surface can fit flatly on the bottom of the mold. The two side walls of the forming mold that are opposite to each other in the length direction also completely match the side shapes on both sides of the base material, so that when the sides of the base material are bent, they can fit tightly on the side walls of the mold. On the side walls on both sides of the forming mold in the width direction, folding adsorption parts are formed at positions corresponding to the bottom folding parts on the base material. These adsorption parts can ensure that the bottom folding part can fit tightly on the side walls of the mold during the forming process, prevent it from loosening or deformation, and ensure that the bottom folding part is connected to the inner surface of the connecting surface.

[0056] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0057] Next, the base material forming the tote bag will be described.

[0058] like Figure 1 As shown, the base material 10 is a sheet-like structure used to form a handbag. Depending on the location where the handbag is formed, the base material 10 can be divided into a bottom surface 110 (rectangular) and side surfaces 120 (rectangular) located on either side of the bottom surface 110 along the length of the base material 10. The side surfaces 120 on either side form opposing connecting surfaces 130 on either side of the width of the base material 10. Furthermore, bottom folds 140 are formed on both sides of the width of the base material 10. The bottom folds 140 are provided with cutouts, dividing the bottom folds 140 into two trapezoidal shapes, which are fixed to the connecting surfaces 130 of the corresponding side surfaces 120. Without affecting the connection strength between the bottom folds and the connecting surfaces 130, the bottom folds 140 can be separated along the cutouts when the bag is folded along the folds. This reduces the chance of squeezing and overlapping of the bottom folds 140 along the folds during folding, improves the flatness of the folded bag, and facilitates storage.

[0059] In addition, the side surfaces 120 on both sides are formed with a pocket fold 150 at the edge facing away from the bottom surface 110, and the handle 160 is connected to the pocket fold 150 through the incision on the pocket fold 150. During the forming process, the pocket fold 150 will bend toward the inside of the pocket and connected to the inner surface of the side surface 120, thereby increasing the pocket strength of the handbag. The handle 160 (end) folded together with the pocket fold 150 is also connected to the inner surface of the side surface 120, which correspondingly enhances the connection strength between the handle 160 and the bag body.

[0060] It should be noted that during the molding process of the base material 10, the connections at various locations of the base material 10 (for example, between the connecting surfaces 130 opposite to each other, between the bottom fold 140 and the inner surface of the connecting surface 130, or between the bag fold 150 and the inner surface of the side surface 120) can be connected by gluing, pressing, etc., and this embodiment does not make the sole limitation to this.

[0061] In this embodiment, the base material 10 is formed from one of paper, polyethylene (PE), and low-density polyethylene, or a mixture of the two materials. All of these materials are impermeable to air, ensuring that they can be adsorbed during the molding process, thereby maintaining the predetermined folded state. Of course, the base material 10 is not limited to the aforementioned materials. Other materials with poor air permeability (e.g., an air permeability of less than 0.05 cm³ / cm²·s) (e.g., nylon fabric) can also ensure adsorption during the production process. Those skilled in the art can design the base material based on actual conditions and specific needs, and this embodiment does not impose any specific limitations on this.

[0062] The forming mold provided by the utility model is described below.

[0063] like Figure 2 As shown, the molding die 20 is in the shape of a rectangular parallelepiped as a whole, wherein the bottom contour of the molding die 20 is adapted to the contour shape of the bottom surface 110 of the base material 10, and the two side walls of the molding die 20 opposite to each other in the length direction are adapted to the shape of the side surfaces 120 on both sides of the base material 10; and the bottom of the molding die 20 is adapted to press the bottom surface 110 of the base material 10, and the side surfaces 120 on both sides of the base material 10 are bent and attached to the corresponding side walls of the molding die 20, and the side surfaces 120 on both sides of the base material 10 and the bottom surface 110 constitute shaped structure and surrounds the forming mold 20.

[0064] And, as Figure 3 As shown, the forming mold 20 has folded edge adsorption portions 201 formed on the side walls on both sides in the width direction thereof at positions corresponding to the bottom folded edges 140 .

[0065] When the forming mold 20 is driven by the driving structure to press the bottom surface 110 of the base material 10, the base material 10 can be bent from the fold between the bottom surface 110 and the side surface 120, thereby forming shaped structure, further, the bottom insert plate located at the lower side of the forming mold 20 can press the bottom folded edge 140 located along the width direction of the base material 10, so that the bottom folded edge 140 can be bent toward the side wall of the forming mold 20, and the folded edge adsorption portion 201 on the side wall of the forming mold 20 can adsorb the bottom folded edge 140 to prevent the bottom folded edge 140 from recovering under the action of inertia after the bottom insert plate is withdrawn, and then the side insert structure located beside the forming mold 20 presses the connecting surface 130, so that the connecting surfaces 130 opposite to each other are bent toward the side wall of the forming mold 20, and the outer surface of the bottom folded edge 140 is connected to the inner surface of the connecting surface 130, and at the same time, the connecting surfaces 130 opposite to each other on the side surfaces 120 on both sides are connected, and the base material 10 is surrounded to form a three-dimensional handbag structure with a rectangular cavity.

[0066] This forming mold 20 prevents the bent bottom fold 140 from re-expanding to its original position after the bottom insert is withdrawn by setting the fold adsorption part 201 on the side wall, ensuring that the outer surface of the bottom fold 140 can be connected to the inner surface of the connecting surface 130, thereby improving the yield of the handbag.

[0067] Specifically, in this embodiment, the forming mold 20 includes a mold body 210 and forming sidewalls 220 detachably connected to both sides of the mold body 210 in the width direction. The hem adsorption portion 201 is provided on the forming sidewalls 220. In this embodiment, the mold body 210 and the forming sidewalls 220 are connected by bolts. Of course, the mold body 210 and the forming sidewalls 220 can also be connected by snap fasteners, which is not specifically limited in this embodiment.

[0068] Further, if Figure 4As shown, the upper end of the mold body 210 has a connecting structure 211. The mold body 210 is connected to the driving structure in the molding equipment that drives the molding mold 20 to press the base material 10 through the connecting structure 211. Specifically, the connecting structure 211 includes a connecting pin 212 provided at the upper end of the mold body 210 and positioning pins 213 spaced apart on both sides of the connecting pin 212. The mold body 210 is connected to the driving structure through the above structure and is thereby driven by the driving structure. Of course, those skilled in the art can design the specific structure of the connecting structure 211 according to actual conditions and specific needs, and this embodiment does not specifically limit this.

[0069] And, as Figure 4 As shown, a plurality of weight-reducing holes 214 are provided at intervals along the height direction in the middle portion of the mold body 210. Specifically, in this embodiment, three weight-reducing holes 214 are provided at intervals along the height direction in the middle portion of the mold body 210 to reduce the weight of the forming mold 20. Of course, the number of weight-reducing holes 214 can also be one, two, four, or a combination thereof, and their contour shapes can also be designed according to specific circumstances and actual needs, and this embodiment does not impose any specific limitations on this.

[0070] The forming mold 20 is composed of a mold body 210 and a forming side wall 220. According to different shapes and specifications, the forming side wall 220 can be disassembled and replaced with a forming side wall 220 that is compatible with the pre-produced handbag to adapt to the production of different handbags. The folding edge adsorption part 201 arranged on the forming side wall 220 ensures that when producing handbags of different specifications, the bottom folding edge 140 in the production process can be adsorbed.

[0071] The hem adsorption unit 201 will be described in detail below.

[0072] like Figure 3 As shown, the hem adsorption portion 201 includes a plurality of hem adsorption holes 202 formed on the side wall of the forming mold 20. When viewed along the width direction, the contour of the region where the plurality of hem adsorption holes 202 are located matches the outer contour of the bottom hem 140. Specifically, the hem adsorption portion 201 includes eight hem adsorption holes 202. The eight hem adsorption holes 202 are divided into two groups of four. The lines connecting the four hem adsorption holes 202 in each group form a trapezoid, which is the same shape as the bottom hem 140 (see Figure 1 Of course, the number of the hem adsorption holes 202 is not limited to eight in the above embodiment, but can also be five, seven or nine or other numbers, which is not specifically limited in this embodiment.

[0073] During the molding process, the multiple folding edge adsorption holes 202 formed on the side wall of the molding mold 20 can adsorb the bottom folding edge 140 from the outer surface of the side wall toward the inner surface of the bottom folding edge 140 when the bottom folding edge 140 is attached to the side wall of the molding mold 20, so as to prevent the bottom folding edge 140 from falling back, and the contour of the area where the multiple folding edge adsorption holes 202 are located is adapted to the outer contour of the bottom folding edge 140, ensuring that the entire bottom folding edge 140 is adsorbed and attached to the outer surface of the side wall, and the adsorption force generated by the multiple folding edge adsorption holes 202 will not act on other structures, thereby avoiding the generation of adsorption force on the connecting surface 130 of the base material 10.

[0074] like Figure 3 As shown, in this embodiment, the folding suction portion 201 further includes a plurality of auxiliary suction holes 203 arranged on the side wall of the forming mold 20, located in the area where the plurality of folding suction holes 202 are located and evenly distributed.

[0075] The diameter of the hem adsorption hole 202 is greater than or equal to the diameter of the auxiliary adsorption hole 203, and the diameter of the hem adsorption hole 202 and the diameter of the auxiliary adsorption hole 203 are within the range of 0.1 mm to 0.25 mm. The diameter of the hem adsorption hole 202 can be 0.25 mm, and the diameter of the auxiliary adsorption hole 203 can be 0.2 mm, or the diameter of the hem adsorption hole 202 can be 0.2 mm, and the diameter of the auxiliary adsorption hole 203 can be 0.1 mm. Those skilled in the art can design according to actual conditions and specific needs, and this embodiment does not impose a sole limitation on this.

[0076] Among them, the multiple auxiliary adsorption holes 203 located in the area where the multiple folding adsorption holes 202 are located and evenly distributed improve the adsorption force on the bottom folding edge 140 and ensure that the entire bottom folding edge 140 can be flatly attached to the outer surface of the side wall.

[0077] In addition, the folding adsorption hole 202 needs to ensure that the bottom folding edge 140 can be adsorbed on the outer wall of the molded side wall 220, so a larger adsorption force needs to be generated, and the folding adsorption hole 202 is located at the outer edge of the bottom folding edge 140. Even if the aperture of the folding adsorption hole 202 is slightly larger, it is not easy to cause the bottom folding edge 140 to deform. The auxiliary adsorption hole 203 is to ensure that the bottom folding edge 140 can be flatly attached to the outer wall of the molded side wall 220, and does not require too much adsorption force. The auxiliary adsorption hole 203 is set in the internal area of ​​the bottom folding edge 140, and its excessively large aperture can easily cause the bottom folding edge 140 to deform.

[0078] Furthermore, the aperture of the folded edge adsorption hole 202 and the aperture of the auxiliary adsorption hole 203 are both within the range of 0.1mm to 0.25mm, which can ensure that the adsorption holes can well adsorb the bottom folded edge 140. If the aperture of the folded edge adsorption hole 202 and the aperture of the auxiliary adsorption hole 203 are larger than the above range, the bottom folded edge 140 may be adsorbed and deformed, and cannot be well connected to the inner surface of the connecting surface 130. If the aperture of the folded edge adsorption hole 202 and the aperture of the auxiliary adsorption hole 203 are smaller than the above range, the folded edge adsorption hole 202 and the auxiliary adsorption hole 203 are easily blocked by fine impurities during use, thereby losing the adsorption function.

[0079] Specifically, in this embodiment, an auxiliary adsorption hole 203 is provided between each group of hem adsorption holes 202. Of course, this embodiment does not impose a sole limitation on the number and distribution of the auxiliary adsorption holes 203.

[0080] More specifically, in order to facilitate the multiple hem adsorption holes 202 to generate adsorption force on the bottom hem 140, such as Figure 5 As shown, an air suction channel 230 extending along the height direction of the mold body 210 and an adsorption cavity 240 connected to the air suction channel 230 are formed between the molding side wall 220 and the mold body 210. One end of the air suction channel 230 is connected to the external air pump and the other end is connected to the adsorption cavity 240.

[0081] Furthermore, the eight hem adsorption holes 202 penetrate the molded side wall 220 and communicate with the adsorption cavity 240 .

[0082] In this embodiment, if Figure 5 As shown, an air suction channel 230 extending along the height direction of the mold body 210 is formed between the molding sidewall 220 and the mold body 210, which can guide the flow of gas and thus introduce gas from the outside. Connected to the air suction channel 230 is an adsorption chamber 240, which generates adsorption force when the gas is extracted, and draws air outward from the multiple fold adsorption holes 202, thereby adsorbing the bottom fold 140. This structure cleverly sets the air suction channel 230 and the adsorption chamber 240 between the molding sidewall 220 and the mold body 210, so that the multiple adsorption holes can generate adsorption force without occupying space next to the molding mold 20, ensuring that the base material 10 can be attached to the outer surface of the molding mold 20.

[0083] In this embodiment, the air suction channel 230 and the adsorption chamber 240 are both opened on the inner surface of the molding side wall 220 close to the mold body 210. The air suction channel 230 extends along the height direction of the mold body 210, and the adsorption chamber 240 is arranged in the width direction in the area where the multiple folded edge adsorption holes 202 are located; and, the air suction channel 230 is provided with a through hole penetrating the molding side wall 220 at one end away from the adsorption chamber 240, which is connected to the external air pump through the through hole, and the other end is connected to the adsorption chamber 240.

[0084] And, as Figure 4-Figure 6 As shown, a seal 250 is further provided between the molding sidewall 220 and the mold body 210, surrounding the adsorption channel and the outer edge of the adsorption cavity 240. It should be noted that the seal 250 may be a rubber pad commonly used in the art, and a plurality of threaded holes are formed on the periphery of the seal 250 so that the seal 250 can be installed between the molding sidewall 220 and the mold body 210 by bolts.

[0085] When the suction channel 230 and the adsorption cavity 240 are provided on the molding side wall 220 of the molding die 20 , the molding side wall 220 has a simple structure and is easy to process, thereby reducing the difficulty of the manufacturing process.

[0086] In addition, the seal 250 is arranged between the molding side wall 220 and the mold body 210, surrounding the outer edge of the adsorption channel and the adsorption cavity 240, thereby ensuring the sealing inside the adsorption cavity 240 and the suction channel 230, preventing gas leakage, and thus maintaining a stable adsorption force.

[0087] In another alternative embodiment, the suction channel 230 and the adsorption chamber 240 are both opened on the end face of the mold body 210 close to the molding side wall 220, the suction channel 230 extends along the height direction of the mold body 210, and the adsorption chamber 240 is arranged in the width direction in the area where the multiple folded edge adsorption holes 202 are located; and, the molding side wall 220 and the suction channel 230 are away from one end of the adsorption chamber 240. A through hole is provided, and the suction channel 230 is connected to an external air pump through the through hole, and the other end of the suction channel 230 is connected to the adsorption chamber 240.

[0088] When the suction channel 230 and the adsorption cavity 240 are opened on the end surface of the mold body 210 close to the molding side wall 220, since the molding side wall 220 does not need to open redundant structures, the thickness of the molding side wall 220 can be reduced, thereby reducing the weight of the molding side wall 220 and facilitating disassembly and assembly.

[0089] More specifically, in this embodiment, each molded sidewall 220 includes a sidewall body 221. A plurality of side suction holes 222 are formed on the side surface 120 in the longitudinal direction of the sidewall body 221 and are spaced apart along the height direction of the mold 20. The side suction holes 222 communicate with the suction channel 230 or the suction chamber 240 from the outer wall of the sidewall body 221. It should be noted that the number of side suction holes 222 can be four, seven, eight, or any other number, and this embodiment is not intended to be a single limitation.

[0090] The side adsorption holes 222 arranged at intervals along the height direction on the side surface 120 of the side wall body 221 can be adsorbed by the side adsorption holes 222 when the side surface 120 of the base material 10 is bent along the folding edge, ensuring that the side surfaces 120 on both sides and the bottom surface 110 form a Shape structure.

[0091] Furthermore, in this embodiment, each molding side wall 220 also includes a side wall flange 223 extending from the two side edges of the side wall body 221 in the length direction, the side wall body 221 is opposite to the corresponding side walls of the molding mold 20 in the width direction, the two side wall flanges 223 extend toward the molding mold 20 and surround the corresponding side walls of the molding mold 20, and the outer wall of the side wall flange 223 in the length direction is flush with the edge of the side wall body 221.

[0092] The side wall flanges 223 extending from the edges of the side wall body 221 cooperate with the plurality of side adsorption holes 222 to enable the bent side 120 of the base material 10 to fit smoothly on the outer wall of the side wall flanges 223, ensuring that the base material 10 can be bent to form Shape structure.

[0093] like Figure 7 As shown, in this embodiment, a bottom adsorption part 260 is further provided at the bottom of the mold body 210. The end edge of the bottom adsorption part 260 is flush with the bottom end surface of the mold body 210. The bottom adsorption part 260 provided at the bottom of the mold body 210 can adsorb the base material 10, ensuring that the molding mold 20 and the base material 10 are accurately linked to enter the molding space for molding operations. Compared with the mold structure with a bottom support structure in the prior art, this molding mold 20 has a light structure, a small number of parts, does not require much space, and reduces the difficulty of assembly production and subsequent maintenance operations.

[0094] Specifically, the bottom suction member 260 includes two suction cups 261 spaced apart along the width direction of the mold body 210. When the molding mold 20 is performing a molding operation, the bottom end surface of the mold body 210 abuts the surface of the base material 10, and the outer edges of the suction cups 261 are in contact with the surface of the base material 10, so that the suction chamber 240 of the suction cups 261 forms a nearly closed environment. An external air pump evacuates the suction chamber 240 of the suction cups 261 through a gas pipeline, and the air in the suction chamber 240 is evacuated. Because the opening of the suction cups 261 is sealed by the base material 10, external air cannot be replenished. As a result, a vacuum state is formed in the suction chamber 240, and the air pressure decreases. Since the external atmospheric pressure is higher than the negative pressure in the suction portion, a pressure differential is formed, and the base material 10 is sucked up by the pressure difference between the external air pressure and the internal vacuum. Of course, the specific piping arrangement between the external air pump and the suction cups 261 can be designed by those skilled in the art according to actual conditions and specific needs, and this embodiment does not specifically limit this.

[0095] More specifically, in this embodiment, the positioning pins 213 spaced apart on either side of the connecting pin 212 at the upper end of the mold body 210 are hollow structures. The two suction cups 261 at the bottom of the mold body 210 are connected to the lower ends of the corresponding positioning pins 213 via gas pipelines, while the upper ends of the positioning pins 213 are connected to an external air pump via gas pipelines, thereby evacuating air from the suction cups 261. Of course, the connection method between the two suction cups 261 and the external air pump is not limited to the structure in the above embodiment. Those skilled in the art can design it according to actual conditions and specific needs, and this embodiment does not impose any specific restrictions on this.
