Description

Technical Field

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

[0002] A handbag is a packaging bag with various shapes and functions, which is widely used in the packaging of various products. For example, handbags can be used for food packaging, electronic product packaging, agricultural product packaging, etc. In addition, there are many types of handbags, including paper bags, kraft paper bags, non-woven bags, etc. In the prior art, when producing handbags, a handbag forming machine is usually used to produce handbags. A handbag forming machine is a device for producing handbags, which is mainly used to manufacture various paper bags and non-woven bags, such as environmentally friendly bags, takeaway bags, wine bags, shoe bags, etc.

[0003] In the prior art, when a handbag is produced by a handbag forming machine, in order to ensure the aesthetics and structural strength of the handbag, the bag mouth of the handbag usually needs to be folded. Generally, the sheet material used to produce the handbag is pre-folded inward to form a folded edge. When the forming mold of the handbag forming machine forms the handbag, since the folded edges of two adjacent connecting surfaces of the handbag need to be plugged and fixed in the width direction of the handbag, the height of one of the two connecting surfaces needs to be changed in the height direction, so that there is a height difference between the two connecting surfaces, thereby facilitating plugging.

[0004] However, in the prior art, when the height of the two front sides is changed in the height direction by the molding die of the handbag so that a height difference is generated between the two connecting surfaces, the front side will pull the bottom side to deflect, and during the deflection process, the bottom side cannot fit on the bottom wall of the molding die. Therefore, when the bottom side is pulled by the front side of the handbag, the bottom side will be deformed, thereby reducing the yield of the handbag and affecting the appearance of the handbag. Utility Model Content

[0005] The utility model aims to solve the problem in the prior art that when a forming mold of a handbag is used to insert and fix two adjacent connecting surfaces of the handbag, the bottom surface is deformed, thereby reducing the yield of the handbag and affecting the appearance of the handbag.

[0006] In order to solve the above problems, the utility model provides a forming mold for a handbag, which is used to provide shape support for the bag body during the process of forming a sheet into a handbag. The bag body includes a bottom surface, two front surfaces arranged opposite to each other in the width direction of the bottom surface, and two side surfaces arranged opposite to each other in the length direction of the bottom surface. The two opposite sides of each side surface are overlapped and fixed to each other.

[0007] The forming mold includes a bottom wall, a pair of supporting walls opposite to each other in the width direction and located on both sides of the bottom wall, and a limiting component adapted to limit the bottom surface of the bag body with the bottom wall, and the bottom wall is relatively rotatably arranged at the lower ends of the pair of supporting walls.

[0008] Among them, the sheet material located below the forming mold is pressed by the bottom wall, and the two front sides in the width direction are bent relative to the bottom surface and close to a pair of supporting walls. The limiting component is engaged with the bottom surface attached to the bottom wall, and the bottom wall rotates relative to the supporting wall around the length direction, linking the bag opening folds at the top of the two sides of each side surface to be plugged in the height direction of the bag body.

[0009] By adopting the above technical scheme, when the bag opening folding edges of the top of the two opposite sides of the upper end of each side are plugged into each other, the two front sides of the bag body of the handbag are attached to a pair of supporting walls, and the bottom surface is always attached to the bottom wall through the limiting component, and then the bottom wall is rotated relative to the supporting wall around the length direction, so as to change the height difference of the top of the two opposite sides of the upper end of each side in the height direction, and finally the bottom wall is flipped back to the original position, so that the bag opening folding edges of the top of the two opposite sides of the upper end of each side are plugged into each other in the height direction of the bag body; in this process, since the bottom surface of the handbag is always attached to the bottom wall through the limiting component, it is not in a free flipping state, but is driven to flip by the bottom wall; therefore, by setting the bottom wall flipping and attaching the bottom surface to the bottom wall through the limiting component, the bottom surface is always kept flat, so that the bag opening folding edges of the top of the two opposite sides of the upper end of each side are plugged into each other, reducing the risk of the bottom surface being deformed by the front surface when the front surface moves in the height direction and is pulled by the front surface, thereby ensuring the aesthetic appearance of the handbag and improving the yield rate of the handbag.

[0010] Furthermore, in one embodiment, the molding mold also includes a pair of side walls arranged relatively on both sides of the bottom wall along the length direction, and the bottom wall, the pair of supporting walls, and the pair of side walls surround a mold cavity; wherein a rotating drive unit connected to the bottom wall is provided in the mold cavity, so that the bottom wall can rotate relative to the pair of supporting walls.

[0011] Furthermore, in one embodiment, both ends of the bottom wall in the length direction are rotatably disposed on the inner side of the lower end of the corresponding side wall through a rotating shaft extending along the length direction; and the rotation driving unit is a driving motor, which is transmission-connected to the bottom wall and can drive the bottom wall to rotate relative to a pair of side walls around the length direction.

[0012] By adopting the above technical solution, when the tops on the two opposite sides of each side upper end are plugged into each other, the bottom wall can be driven by the driving motor, and the bottom wall rotates relative to a pair of side walls through the rotating shaft, thereby changing one of the tops on the two opposite sides of each side upper end to move down and the other to rise, so that the tops on the two opposite sides of each side upper end of the bag body have a height difference with each other, and then the driving motor drives the bottom wall to rotate and return to the initial position, thereby making the tops on the two opposite sides of each side upper end return to the initial position, and finally achieving the plugging of the tops on the two opposite sides of each side upper end. In this process, the driving motor directly drives the bottom wall, so that the molding mold has the advantages of fast response speed and simple structure.

[0013] Furthermore, in one embodiment, the lower ends of a pair of support walls are each provided with a rotation axis extending along the length direction, and the two ends of the bottom wall in the width direction are respectively rotatably connected to their respective corresponding rotation axes, and the bottom wall can rotate relative to the pair of support walls around the length direction through a pair of rotation axes.

[0014] In addition, the rotation drive unit includes a driving source arranged in the mold cavity corresponding to at least one supporting wall, and a transmission component that is transmission-connected to the driving source. The driving end of the transmission component is transmission-connected to the inner wall surface of a corresponding supporting wall, and can drive the supporting wall to reciprocate along the height direction of the molding mold, and link the bottom wall to rotate relative to the supporting wall around the length direction.

[0015] By adopting the above technical scheme, when the tops of the two opposite sides of the upper end of each side are plugged into each other, the driving source of the rotating driving unit drives the transmission assembly, so that the transmission assembly can drive the supporting wall to reciprocate along the height direction of the forming mold, and link the bottom wall to rotate relative to the supporting wall around the length direction, so that the tops of the two opposite sides of the upper end of each side have a height difference in the height direction, and then the bottom wall flips back to its original position around the length direction, so that the bag opening of the tops of the two opposite sides of the upper end of each side is folded and plugged into each other in the height direction of the bag body; in this process, a pair of side walls guide a pair of side surfaces of the bag body corresponding to it when they move in the height direction, so that the tops of the two opposite sides of the upper end of each side can be accurately and reliably plugged into.

[0016] Further, in one embodiment, the limiting component includes a plurality of limiting members arranged on the bottom wall at intervals along the length direction, and an end portion of each limiting member is exposed from the outer surface of the bottom wall.

[0017] By adopting the above technical solution and providing a plurality of limiting components, the limiting effect of the limiting component on the bottom surface of the bag body can be further improved, so that the fit between the bottom surface and the bottom wall is higher.

[0018] Furthermore, in one embodiment, each limiting member is a suction cup connected to an air source, and a plurality of suction cup mounting holes are formed on the bottom wall. The plurality of suction cup mounting holes are evenly distributed throughout the bottom wall, and each suction cup is respectively arranged in a corresponding suction cup mounting hole, and the edge of the suction nozzle of the suction cup is flush with the outer wall surface of the bottom wall; the air source is connected to the air inlet of each suction cup through an air inlet pipe.

[0019] By adopting the above technical scheme, when the bottom surface of the bag needs to be attached to the bottom wall during the forming process, the bottom surface is sucked and attached to the bottom wall by multiple suction cups, and because the suction cups limit the bottom surface by adsorption, damage to the bottom surface can be avoided, thereby ensuring the aesthetics of the bag; and after the bag is formed, the suction cups can quickly release the limit on the bottom surface, so that the formed bag can be quickly transported to the next workstation, thereby improving the forming rate of the bag.

[0036] The bag mouth is one of the parts of the handbag that is most susceptible to wear and tear. By folding the bag mouth, the durability of the bag mouth edge can be effectively increased and the service life of the handbag can be extended. However, after the bag mouth is folded, when the handbag is formed by the forming mold of the handbag forming machine, since the two adjacent connecting surfaces of the handbag need to be plugged and fixed in the width direction of the handbag, the height of the two connecting surfaces needs to be changed in the height direction, so that there is a height difference between the two connecting surfaces, so as to facilitate plugging.

[0037] However, in the prior art, when the height of the two front sides is changed in the height direction by the molding die of the handbag so that a height difference is generated between the two connecting surfaces, the front side will pull the bottom side to deflect, and during the deflection process, the bottom side cannot fit on the bottom wall of the molding die. Therefore, when the bottom side is pulled by the front side of the handbag, the bottom side will be deformed, thereby reducing the yield of the handbag and affecting the appearance of the handbag.

[0038] To this end, the utility model provides a forming mold for a handbag. When the bag body of the handbag is formed, the two front sides of the bag body are attached to a pair of supporting walls, and the bottom surface is always attached to the bottom wall through a limiting component. Then the bottom wall is rotated relative to the pair of supporting walls around the length direction, so that the tops of the two opposite sides of the upper end of each side surface have a height difference in the height direction. Finally, the bottom wall is flipped back to its original position, so that the bag opening tops of the two opposite sides of the upper end of each side surface are folded and connected to each other in the height direction of the bag body. In this process, since the bottom surface of the bag body is always attached to the bottom wall through the limiting component, it is not in a free flipping state, but is driven to flip by the bottom wall, and the bottom surface is not easy to deform, thereby ensuring the beautiful appearance of the handbag and improving the yield of the handbag.

[0039] In order to more clearly introduce the solution of the present invention, an example description is given below in conjunction with the accompanying drawings.

[0040] like Figure 1 and Figure 2 As shown, the structure of the handbag is first described as follows:

[0041] The handbag 1 includes a bag body 10, which includes a bottom surface 102, two front surfaces 100 arranged opposite to each other in the width direction W of the bottom surface 102, and two side surfaces 101 arranged opposite to each other in the length direction L of the bottom surface 102. In addition, the two opposite sides of each side surface 101 are overlapped and fixed to each other, and in the height direction H, a bag mouth folded edge 103 is formed at the top of the bag body 10, and a handle 11 is also arranged on the bag mouth folded edge 103, so as to facilitate taking the handbag 1.

[0042] It should be understood that the two opposite sides of each side 101 are overlapped and fixed to each other, that is, each side 101 includes a pair of connecting surfaces 104; the pair of connecting surfaces 104 are arranged along the width direction W, and one end of one of the connecting surfaces 104 is overlapped and fixed to a section of the other connecting surface 104, and in the height direction H, the top of each connecting surface 104 is provided with a pocket folding edge 103, and the pocket folding edges 103 of the pair of connecting surfaces 104 are plugged and fixed to each other. In addition, the connection position of the two connecting surfaces 104 in each side 101 of the bag body 10 is not limited, for example, it can be at one-half of the width direction W of the side 101 of the bag body 10, or it can be at one-third of the width direction W of the side 101 of the bag body 10, etc., and this embodiment is not limited here.

[0043] The material of the handbag 1 is not limited, for example, it can be non-woven fabric, plastic, paper, etc.

[0044] The purpose of the utility model is to improve the aesthetics and yield of a three-dimensional bag, and for this purpose a forming mold 2 of a handbag 1 is provided. The overall structure of the forming mold 2 is explained below.

[0045] like Figure 1-5 As shown, a molding mold 2 is provided, which is used to provide shape support for the bag body 10 during the process of forming the sheet into a handbag 1, and the molding mold 2 includes a bottom wall 21, a pair of support walls 20 opposite to each other in the width direction W and located on both sides of the bottom wall 21, and a limiting component 24 adapted to limit the bottom surface 102 of the bag body 10 with the bottom wall 21, and the bottom wall 21 can be relatively rotatably arranged at the lower end of the pair of support walls 20.

[0046] It should be understood that, in the side wall design of the forming mold 2 , a pair of support walls 20 are respectively matched with the two front surfaces 100 of the bag body 10 of the handbag 1 , and the bottom wall 21 is matched with the bottom surface 102 of the bag body 10 .

[0047] Specifically, when the bag body 10 of the handbag 1 is formed by this molding mold 2, the sheet material located below the molding mold 2 is pressed by the bottom wall 21, and the two front sides 100 in the width direction W are bent relative to the bottom surface 102 and close to a pair of support walls 20, and the limiting component 24 is engaged with the bottom surface 102 attached to the bottom wall 21, thereby realizing the preliminary forming of the bag body 10.

[0048] More specifically, when the bag opening folds 103 at the tops of the two opposite sides of the upper end of each side surface 101 are plugged, the two front faces 100 of the bag body 10 of the handbag 1 are attached to the pair of supporting walls 20, and the bottom face 102 is always attached to the bottom wall 21 through the limiting component 24, and the bottom wall 21 is rotated relative to the supporting wall 20 around the length direction L, thereby changing the height difference between the tops of the two opposite sides of the upper end of each side surface 101 in the height direction H (see Figure 3 ), and then the bottom wall 21 is turned back to its original position along the length direction L, so that the bag opening folds 103 at the top of the opposite sides of the upper end of each side 101 are connected to each other in the height direction H of the bag body 10 (see Figure 4 ). In this process, since the bottom surface 102 of the handbag 1 is always attached to the bottom wall 21 through the limiting component 24, the bottom surface 102 always remains flat and is not in a free flipping state, but is driven to flip by the bottom wall 21; therefore, by setting the bottom wall 21 to flip and the bottom surface 102 is always attached to the bottom wall 21 through the limiting component 24, the bag opening folding edges 103 at the top of the two opposite sides of the upper end of each side surface 101 are plugged into each other, reducing the risk of the bottom surface 102 being deformed by the front surface 100 when the front surface 100 moves in the height direction H, thereby ensuring the aesthetic appearance of the handbag 1 and improving the yield rate of the handbag 1.

[0049] It should be noted that in order to achieve that the pocket folded edges 103 at the top of the two opposite sides of the upper end of each side 101 can be plugged into each other, the tops of the two opposite sides of each side 101 at least partially overlap in the width direction W, so that the pocket folded edges 103 at the top of the two opposite sides can be plugged into each other.

[0050] It should be understood that in the present invention, when the bottom surface 102 is in contact with the bottom wall 21 and the two front surfaces 100 are in contact with a pair of support walls 20, the length direction and width direction of the bottom surface 102 correspond one-to-one with the length direction L and the width direction W of the bottom wall 21, respectively, indicating the same direction, and the height direction of the bag body 10 corresponds to the height direction H of the molding mold 2, indicating the same direction.

[0051] Furthermore, the specific structure of the molding die 2 is further explained below.

[0052] In one embodiment, if Figure 5 and Figure 6 As shown, the molding mold 2 also includes a pair of side walls 22 relatively arranged on both sides of the bottom wall 21 along the length direction L, and the bottom wall 21, the pair of support walls 20, and the pair of side walls 22 surround a mold cavity 25; wherein, a rotating drive unit 26 transmission-connected to the bottom wall 21 is provided in the mold cavity 25, and the bottom wall 21 can be driven to rotate relative to the pair of support walls 20 by the rotating drive unit 26.

[0053] Specifically, the rotation drive unit 26 is arranged in the mold cavity 25. On the one hand, the rotation drive unit 26 can be protected by the bottom wall 21, a pair of support walls 20, and a pair of side walls 22 to prevent the rotation drive unit 26 from malfunctioning due to accidental touch by the staff during operation, and causing harm to the staff; on the other hand, the space occupied by the molding mold 2 will not be increased. In addition, since the rotation drive unit 26 is in the mold cavity 25, the rotation drive unit 26 is prevented from interfering with the engagement process of the limiting component 24 with the bottom surface 102 attached to the bottom wall 21 when the sheet is pressed by the bottom wall 21 and the two front sides 100 in the width direction W are bent relative to the bottom surface 102 and close to the pair of support walls 20.

[0054] More specifically, the rotational arrangement of the bottom wall 21 and the arrangement of the rotational driving unit 26 are not limited.

[0055] Optionally, in a feasible implementation, as Figure 5-Figure 8 As shown, in the height direction H, the lower ends of a pair of support walls 20 are each provided with a rotation axis 200 extending along the length direction L, and the two ends of the bottom wall 21 in the width direction W are respectively rotatably connected to the corresponding rotation axis 200, and the bottom wall 21 can rotate around the length direction L relative to the pair of support walls 20 through a pair of rotation axis 200.

[0056] Specifically, the rotation drive unit 26 includes a driving source arranged in the mold cavity 25 corresponding to at least one support wall 20, and a transmission assembly that is transmission-connected to the driving source, and the driving end of the transmission assembly is transmission-connected to the inner wall surface of a corresponding support wall 20. When the driving source of the rotation drive unit 26 drives the transmission assembly, the transmission assembly can drive the support wall 20 to reciprocate along the height direction H of the molding mold 2, and drive the bottom wall 21 to rotate relative to the support wall 20 around the length direction L.

[0057] More specifically, when the bag body 10 of the handbag 1 is formed, the sheet material located below the forming mold 2 is pressed by the bottom wall 21, the two front sides 100 in the width direction W are bent relative to the bottom surface 102 and close to a pair of support walls 20, and the two side surfaces 101 of the bag body 10 in the length direction L are bent relative to the bottom surface 102 and close to a pair of side walls 22, and the limiting component 24 is engaged with the bottom surface 102 attached to the bottom wall 21, thereby realizing the preliminary forming of the bag body 10.

[0058] More specifically, when the tops of the two opposite sides of the upper end of each side 101 are plugged into each other, the driving source of the rotating driving unit 26 drives the transmission assembly, so that the transmission assembly can drive the supporting wall 20 to move back and forth along the height direction H of the forming mold 2, and link the bottom wall 21 to rotate relative to the supporting wall 20 around the length direction L, so that the tops of the two opposite sides of the upper end of each side 101 have a height difference in the height direction H, and then the bottom wall 21 flips back to its original position around the length direction L, so that the bag mouth folds 103 of the tops of the two opposite sides of the upper end of each side 101 are plugged into each other in the height direction H of the bag body 10; in this process, a pair of side walls 22 guides a pair of side surfaces 101 corresponding to the bag body 10 when they move in the height direction H, so that the tops of the two opposite sides of the upper end of each side 101 can be accurately and reliably plugged into.

[0059] In one embodiment, Figure 5 As shown, the molding die 2 further includes a top wall 23 , which is at a top end away from the bottom wall 21 , and when viewed along the height direction H of the molding die 2 , the outer wall surface of any one of the pair of support walls 20 is within the edge contour of the top wall 23 .

[0060] Specifically, by setting the top wall 23, the forming mold 2 can be installed on the mounting position on the handbag 1 forming machine. When the bag body 10 is formed, other structures on the handbag 1 forming machine (such as the folding mechanism) will not affect the forming process of the bag body 10.

[0061] Optionally, in one embodiment, Figure 5 As shown, in order to facilitate the installation of the forming mold 2 on the handbag 1 forming machine, a mounting seat 27 is also provided on an outer wall surface of the top wall 23 away from the bottom wall 21. By providing the mounting seat 27, the forming mold 2 can be conveniently installed on the mounting position of the forming machine.

[0062] Furthermore, the rotation driving unit 26 can drive one supporting wall 20 to move along the height direction H, and can also drive a pair of supporting walls 20 to move along the height direction H.

[0063] For example, in one embodiment, Figure 6-Figure 8As shown, one of the pair of support walls 20 is fixed relative to the top wall 23, and the other support wall 20 can reciprocate relative to the top wall 23 along the height direction H; and a pair of rotation drive units 26 are arranged side by side on the inner wall surface of the other support wall 20, and the driving end of each rotation drive unit 26 is transmission-connected to the inner wall surface of the other support wall 20.

[0064] Specifically, each rotation drive unit 26 includes a telescopic cylinder 201 as a driving source, and a connecting seat 202 as a transmission component. The fixed end of the telescopic cylinder 201 is fixedly installed on the inner wall surface of the top wall 23, and the driving end extends along the height direction H. One end of the connecting seat 202 is fixedly installed on the inner wall of the movable support wall 20, and the other end extends along the width direction W and is connected to the driving end of the telescopic cylinder 201.

[0065] More specifically, when the tops of the two opposite sides of the upper end of each side 101 are plugged into each other, the connecting seat 202 is driven by the driving end of the telescopic cylinder 201, so that the connecting seat 202 drives the movable supporting wall 20 to move up or down in the height direction H, and then drives the bottom wall 21 to rotate relative to the pair of supporting walls 20 around the length direction L, changing one of the tops of the two opposite sides of the upper end of each side 101 to move down or up, so that a height difference is generated between the tops of the two opposite sides of the upper end of each side 101 of the bag body 10, and then, the driving end of the telescopic cylinder 201 drives the connecting seat 202, so that the connecting seat 202 drives the movable supporting wall 20 to reset to its initial position, and then drives the bottom wall 21 to rotate relative to the pair of supporting walls 20 around the length direction L to its initial position, thereby realizing the plugging of the tops of the two opposite sides of the upper end of each side 101. During this process, by setting up a pair of rotation drive units 26, the movable support wall 20 can run smoothly during the movement; and, since the materials used to make the three-dimensional bags are generally flammable (such as paper), the rotation drive unit 26 is set as a telescopic cylinder 201 to pneumatically drive the support wall 20, which also improves the safety of the molding mold 2.

[0066] In another embodiment, the pair of support walls 20 can both reciprocate relative to the top wall 23 along the height direction H; and the driving end of the rotation driving unit 26 is transmission-connected to the inner wall surfaces of the pair of support walls 20 .

[0067] Specifically, the rotation drive unit 26 includes a pair of electric telescopic rods arranged on the top wall 23 at intervals along the length direction L, and a pair of transmission rods corresponding to the pair of electric telescopic rods and serving as transmission components, and the pair of transmission rods correspond to the pair of support walls 20 one by one; the fixed ends of a pair of telescopic cylinders 201 are fixedly mounted on the inner wall surface of the top wall 23, and the driving ends extend along the height direction H, one end of the transmission rod is fixedly mounted on the inner side wall of the corresponding support wall 20, and the other end extends along the width direction W and is fixedly connected to the driving end of the corresponding electric telescopic rod. It should be understood that when one support wall 20 and the other support wall 20 of the pair of support walls 20 are both positioned in the height direction H, the moving directions are opposite, for example, when one support wall 20 moves upward, the other support wall 20 moves downward.

[0068] More specifically, when the tops on the two opposite sides of the upper end of each side surface 101 are plugged into each other, the driving ends of a pair of telescopic cylinders 201 respectively drive their corresponding transmission rods, and one of the pair of transmission rods links its corresponding support wall 20 to move downward, and the other links its corresponding support wall 20 to move upward, and at the same time drives the bottom wall 21 to rotate relative to the pair of support walls 20 around the length direction L, one of the tops on the two opposite sides of the upper end of each side surface 101 moves downward, and the other moves upward, thereby generating a height difference in the height direction H.

[0069] Furthermore, the driving ends of a pair of telescopic cylinders 201 respectively drive their corresponding transmission rods, and one of the pair of transmission rods links its corresponding support wall 20 to move up, and the other links its corresponding support wall 20 to move down, while driving the bottom wall 21 to rotate toward the initial position relative to the pair of support walls 20 around the length direction L, and one of the tops on the two opposite sides of the upper end of each side 101 moves up, and the other top moves down, so that the tops on the two opposite sides of the upper end of each side 101 are connected to each other; in this process, compared with the movement of a single support wall 20; in the mode in which a pair of support walls 20 both move, the movement displacement of each support wall 20 can be further reduced. Therefore, this arrangement can further speed up the production efficiency of the handbag 1.

[0070] Optionally, in another feasible embodiment, the two ends of the bottom wall 21 in the length direction L are rotatably disposed on the inner side of the lower end of the corresponding side wall 22 via a rotating shaft extending along the length direction L, so that the two ends of the bottom wall 21 in the length direction L are rotatably connected to the respective corresponding side walls 22; and the rotation drive unit 26 is a drive motor, which is transmission-connected to the bottom wall 21 and can drive the bottom wall 21 to rotate around the length direction L relative to a pair of side walls 22.

[0071] Specifically, when the tops of the two opposite sides of the upper end of each side 101 are plugged into each other, the bottom wall 21 can be driven by a driving motor, and the bottom wall 21 rotates relative to a pair of side walls 22 through a rotating shaft, thereby changing one of the tops of the two opposite sides of the upper end of each side 101 to move down and the other to rise, so that the tops of the two opposite sides of the upper end of each side 101 of the bag body 10 have a height difference with each other, and then the driving motor drives the bottom wall 21 to rotate and return to the initial position, thereby making the tops of the two opposite sides of the upper end of each side 101 return to the initial position, and finally achieving the plugging of the tops of the two opposite sides of the upper end of each side 101. In this process, the driving motor directly drives the bottom wall 21, so that the molding mold 2 has the advantages of fast response speed and simple structure.

[0072] More specifically, the setting method and setting position of the rotating shaft are not limited.

[0073] For example, in one embodiment, when viewed along the length direction L, the rotating shaft is located at the middle position of the lower end of the bottom wall 21 in the width direction W; thereby, when the bottom wall 21 rotates, the rotation angles on both sides in the width direction W are the same, thereby achieving accurate insertion of the tops of the two opposite sides of the upper end of each side surface 101.

[0074] In another embodiment, when viewed along the length direction L, the rotation axis is located at one end of the lower end of the bottom wall 21 in the width direction W.

[0075] Furthermore, in a feasible embodiment, the molding mold 2 also includes a pair of limit frames movably arranged on the top wall 23 and corresponding one-to-one to the pair of support walls 20. In the width direction W of the molding mold 2, the pair of limit frames can limit the front side 100 attached to the support wall 20 to prevent the front side 100 from tilting outward relative to the support wall 20 due to the bottom wall 21 driving the bottom surface 102 during the flipping process.

[0076] It should be understood that, for limiting the front 100 and the side 101 of the bag body 10, a molding groove may also be provided on the molding station of the molding machine to limit the front 100 and the side 101, and this is not limited in this embodiment.

[0077] Furthermore, the structure and arrangement of the limiting component 24 are explained below.

[0078] In one embodiment, Figure 5-Figure 7As shown, the limiting component 24 includes a plurality of limiting components 203 arranged on the bottom wall 21 at intervals along the length direction L, and the end of each limiting component 203 is exposed from the outer surface of the bottom wall 21. By providing a plurality of limiting components 203, the limiting effect of the limiting component 24 on the bottom surface 102 of the bag body 10 can be further improved, so that the fit between the bottom surface 102 and the bottom wall 21 is higher. It should be understood that the number of the plurality of limiting components 203 is not limited, for example, it can be 2, 4, 5, etc., and this embodiment is not limited here.

[0079] Specifically, the structure and arrangement of the limiting member 203 are not limited.

[0080] In one embodiment, if Figure 6 and Figure 7 As shown, each limiting member 203 is a suction cup 204 connected to the air source, and a plurality of suction cup 204 mounting holes are formed on the bottom wall 21. The plurality of suction cup 204 mounting holes are evenly distributed and penetrate the bottom wall 21. Each suction cup 204 is respectively arranged in a corresponding suction cup 204 mounting hole, and the suction nozzle edge of the suction cup 204 is flush with the outer wall surface of the bottom wall 21; the air source is connected to the air inlet of each suction cup 204 through the air inlet pipe 205 of the suction cup 204. It should be understood that the number of the plurality of suction cup 204 mounting holes is not limited, for example, it can be 2, 4, 5, etc., and this embodiment is not limited here.

[0081] Specifically, during the molding process of the bag body 10, when the bottom surface 102 needs to be attached to the bottom wall 21, the bottom surface 102 is adsorbed and attached to the bottom wall 21 through multiple suction cups 204, and because the suction cups 204 limit the bottom surface 102 by adsorption, damage to the bottom surface 102 can be avoided, thereby ensuring the aesthetics of the bag body 10; and after the bag body 10 is molded, the suction cups 204 can quickly release the limit on the bottom surface 102, so that the molded bag body 10 can be quickly transported to the next workstation, thereby improving the molding rate of the bag body 10.

[0082] In another embodiment, the limiting component 24 includes a clamping plate arranged opposite to the outer surface of the bottom wall 21, the clamping plate can move relative to the bottom wall 21 to clamp the bottom surface 102 on the outer surface of the bottom wall 21, and can rotate synchronously with the bottom wall 21 around the length direction L relative to the support wall 20.

[0083] Specifically, during the molding process of the bag body 10, when the bottom surface 102 needs to be attached to the bottom wall 21, the bottom surface 102 is clamped on the bottom wall 21 by moving the clamping plate, thereby limiting the bottom surface 102 by clamping, which can improve the degree of limitation of the bottom surface 102, thereby avoiding the risk of the bottom surface 102 shifting in the process of rotating with the bottom wall 21, and further improving the reliability of the bag body 10 during the molding process.

[0084] In summary, the advantages of this molding mold 2 are as follows: when the bag body 10 of the handbag 1 is formed, multiple limiting components 203 reliably limit the bottom surface 102 to fit on the bottom wall 21, and the bottom wall 21 is driven to rotate relative to a pair of support walls 20 around the length direction L by the rotation drive unit 26, so that the tops of the two opposite sides of the upper end of each side 101 have a height difference in the height direction H, and then the rotation drive unit 26 drives the bottom wall 21 to flip back to its original position, so that the bag opening folds 103 of the tops of the two opposite sides of the upper end of each side 101 are connected to each other in the height direction H of the bag body 10; the risk of the bottom surface 102 being deformed by the front face 100 when it moves in the height direction H is reduced, thereby ensuring the aesthetic appearance of the handbag 1 and improving the yield of the handbag 1.
