Description

Technical Field

[0001] The invention relates to the technical field of handbag manufacturing, and in particular to a handbag forming die and a forming die assembly. Background Art

[0002] As a portable storage container, handbags have become an indispensable part of our daily life. They are designed with handles or shoulder straps for people to carry or shoulder. They are usually made of various materials, such as cloth, leather, plastic, paper, etc. For handbags of various materials, the structural stability and aesthetics of the handbags are crucial factors in their design and manufacturing process. It is not only related to the user experience, but also directly affects the practicality and durability of the handbags. Therefore, more and more handbags are provided with inward folded edges at the bag opening. The folded edges can not only enhance the structural stability of the handbags, but also improve the overall aesthetics of the handbags. And the bag opening folded edges can also provide additional protection to reduce the friction and discomfort of the handbags on the hands. Especially when the handbag is loaded with heavy objects, the folded edges can disperse the weight, reduce the pressure on the skin and muscles of the hands, and make the user more comfortable.

[0003] In the prior art, the production of handbags with bag opening folds usually includes the steps of sheet cutting, forming, folding and fixing the folds. Especially for materials that are not easy to deform, such as paper bags, if the connection of the bag opening folds is fixed by a conventional multi-layer overlapping fixing method, not only will the flatness of the bag opening folds of the handbags be poor, affecting the aesthetics, but also the structural reinforcement performance of the bag opening folds on the handbags will be greatly weakened. In this regard, in the prior art, when producing handbags made of materials that are not easy to deform, after the bag body is formed, the bag opening folds are processed by using corresponding equipment, and the process includes multiple processes such as folding outward, gluing, and folding inward. Not only are there many processes in the process, which affects the production efficiency of the handbags, but the probability of the folds being torn and damaged by multiple folding is also high, which also leads to a low yield of the handbags.

[0004] Therefore, the prior art has the problems of low efficiency and low yield when producing handbags with bag opening folds. Summary of the invention

[0005] The purpose of the present invention is to solve the above-mentioned defects existing in the prior art when producing a handbag with a bag opening folded edge, and to provide a forming mold that can be used for the production of a handbag with a bag opening folded edge.

[0006] In order to more clearly introduce the technical solution provided by the present invention, the structure of the handbag is first described as follows:

[0007] The handbag comprises 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, and opposite sides of the two side surfaces are overlapped with each other.

[0008] In order to improve the production efficiency and yield rate of the above-mentioned structure handbag.

[0009] In the first aspect, the present invention provides a forming mold for a handbag, which can be used to provide shape support for the bag body during the process of forming a sheet into a handbag. When used in a handbag forming device, it can achieve simultaneous forming of the bag body and the bag mouth fold, and can simultaneously improve the production efficiency and yield rate of the above-mentioned structure handbag.

[0010] Specifically, this molding mold includes a mold body, and two first side walls, two second side walls, a bottom wall, and two bag body limiting components arranged on the mold body; wherein, the two first side walls are respectively adapted to the two front sides of the handbag, the two second side walls are respectively adapted to the two side surfaces of the handbag, the bottom wall is adapted to the bottom surface of the handbag, and the two bag body limiting components are respectively adapted to the two first side walls, at least one of the two first side walls is reciprocatingly connected to the corresponding side portion of the mold body along the height direction of the mold body, and each bag body limiting component and a corresponding first side wall jointly limit the front side of a corresponding handbag.

[0011] With a forming mold of this structure, during the bag body forming process of a handbag, before the sheet is formed, folded edges are pre-folded inward at both ends of the sheet in the length direction, and when the sheet is conveyed to the position of the forming mold and pressed by the forming mold so that the folded edges of the bag opening pre-folded inward at both ends of the sheet in the length direction are close to the second side wall, at least one of the two first side walls and the front side of an adjacent handbag move back and forth relative to the mold body. For example, when the sheet is pressed by the forming mold so that the folded edges of the bag opening pre-folded inward at both ends of the sheet in the length direction are close to the second side wall, the two front sides of the handbag are respectively fixed to the corresponding first side walls by two bag body limiting assemblies, wherein the first side wall moves downward in the height direction of the mold body, and the other first side wall The first side wall of the handbag is fixed relative to the mold body; or the first side wall thereof moves upward along the height direction of the mold body, and the other first side wall is fixed relative to the mold body; or the first side wall thereof moves upward along the height direction of the mold body, and the other first side wall moves downward along the height direction of the mold body; the above-mentioned various operations can make the two front sides of the handbag misaligned in the height direction of the mold body, so that the two side parts adjacent to the two front sides can be misaligned, and at this time, the connecting part of the bag mouth folding edge of the handbag is also misaligned up and down, and when the two first side walls are reset, the bag mouth folding edges of the misaligned connecting parts can be plugged into each other, and then the corresponding operation of the pressing structure can be used to realize the simultaneous forming of the bag body and the bag mouth folding edge of the handbag. Accordingly, when the handbag is made by the forming mold of the handbag provided by the present invention, the whole handbag can be made after the forming process is completed, and there is no need to set up a separate bag mouth folding device to perform other operations on the bag body after forming, which not only simplifies the making process of the handbag, but also improves the making efficiency of the handbag, and can also avoid the probability of the bag body of the handbag being pulled and damaged by other operations after forming.

[0012] Furthermore, because the molding mold provided by the present invention utilizes the relative movement of the two first side walls when realizing bag body molding, the bag opening folding edge connection of the handbag can be connected in a plug-in manner. This not only avoids the bag opening folding edge connection of the handbag from affecting the aesthetics due to poor flatness, but the plug-in connection method is more conducive to strengthening the bag body structure of the handbag by the bag opening folding edge.

[0013] Therefore, by using the molding die provided by the present invention, a more beautiful handbag with a stable bag structure can be produced with high efficiency and high yield rate.

[0014] Furthermore, in order to improve the success rate of the bag opening folding edge insertion, the molding mold provided by the present invention also includes two folding edge opening components respectively arranged at the corresponding positions of the two second side walls. When the bag opening folding edges of the sheet material that are pre-folded inward at both ends in the length direction are pressed close to the second side wall, the folding edge opening components can make the bag opening folding edge of the two side surfaces of the handbag that is farther away from the second side wall open.

[0015] Utilizing such a structure, when the sheet of the handbag is pre-folded, even if the opening angle of the fold is small, or when other factors such as static electricity cause the fold to fit the bag body, when the sheet is pressed close to the second side wall, the fold opening component can accurately open the fold of the inserted fold, and at least one of the two first side walls drives at least one front of the handbag and drives at least one of the two side surfaces of the handbag to move back and forth relative to the mold body, so that the bag opening fold of the other of the two side surfaces of the handbag can be inserted into the bag opening fold of one side, thereby achieving smooth insertion of the two folds, which can greatly improve the success rate of bag opening fold insertion and further improve the yield rate of handbag production.

[0016] In the second aspect, the present invention also provides a molding mold assembly for a handbag, which includes a receiving platform, which forms a molding area, and a molding mold as above is arranged at a position above the receiving platform corresponding to the molding area; the molding mold is movably arranged above the molding area in a vertical direction, and when the sheet material is conveyed to the molding area, the molding mold moves from top to bottom so that the two front sides of the handbag are respectively attached to the two first side walls of the molding mold.

[0017] Since the molding mold assembly adopts the molding mold with the above structure, the molding mold assembly can realize the simultaneous molding of the bag body and the bag opening folding edge of the handbag when realizing the handbag molding process, which not only makes the function of the molding mold assembly more diversified, but also greatly improves the production efficiency of the handbag.

[0052] The bag opening is one of the most easily worn parts of a handbag. By folding the bag opening, the durability of the bag opening edge can be effectively increased and the service life of the handbag can be extended. However, for handbags made of materials that are not easy to deform, the bag opening folding cannot be connected by simple overlapping connection. Otherwise, not only will the flatness of the bag opening folding connection be poor, but it will also greatly weaken the bag opening folding's structural reinforcement performance on the bag.

[0053] In this regard, the folding of the mouth of a handbag made of non-deformable material often needs to be done after the bag body is formed. For example, a separate folding device is set after the bag body forming device of the handbag, and the folding device is used to fold the mouth of the handbag to avoid the above problems.

[0054] However, since the three-dimensional structure of the bag body has been formed after the molding process of the handbag, if the bag body is to be folded, it not only requires the coordinated processing of multiple mechanisms, but also the process is relatively complicated, affecting the production efficiency of the handbag. In addition, there is a risk of damaging the bag body during the folding operation, affecting the yield of the handbag.

[0055] Therefore, how to improve the production efficiency and yield rate of the above-mentioned structured handbags is an urgent problem to be solved in the handbag field.

[0056] To this end, the present invention provides a forming mold that can be used to make a handbag. When the forming mold is used to make the handbag, the two first side walls are moved relative to each other, so that the bag mouth folding edge connection of the handbag can be connected in a plug-in manner, and then the bag body and the bag mouth folding edge of the handbag can be formed at the same time by using corresponding operations of pressing and other structures, which can improve the production efficiency of the handbag and avoid the probability of the bag body of the handbag being damaged by pulling by other operations after forming, thereby achieving high efficiency and high yield production of a more beautiful handbag with a bag body structure.

[0057] In order to more clearly describe the solution of the present invention, an example description is given below in conjunction with the accompanying drawings.

[0058] See also Figure 1 First, the structure of the handbag 10 is described as follows:

[0059] The handbag 10 includes a bottom surface 103 , two front surfaces 101 disposed opposite to each other in the width direction of the bottom surface 103 , and two side surfaces 102 disposed opposite to each other in the length direction of the bottom surface 103 , and opposite sides of the two side surfaces 102 overlap each other.

[0060] It should be understood that, in the present invention, the connection position of the two sides 102 of the handbag 10 is not limited, for example, it can be located at half of the width direction of the side 102 of the handbag 10 (such as Figure 1 As shown), it may also be located near one end of the side surface 102 of the handbag 10 in the width direction.

[0061] The material of the handbag 10 is not limited, for example, it can be non-woven fabric, leather, plastic, paper, etc.

[0062] The purpose of the present invention is to achieve high efficiency and high yield in producing the above-mentioned handbag 10 which is beautiful and has a stable bag structure.

[0063] To this end, in one embodiment of the present invention, see Figure 2 and Figure 3 , a forming mold 100 for a handbag is provided, which can be used to provide shape support for the bag body during the process of forming a sheet 20 into a handbag 10. The forming mold 100 includes a mold body 110, and two first side walls 120, two second side walls 130, a bottom wall 140, and two bag body limiting components 150 arranged on the mold body 110.

[0064] In the side wall design of each molding die 100, the two first side walls 120 are respectively matched with the two front faces 101 of the handbag 10, the two second side walls 130 are respectively matched with the two side faces 102 of the handbag 10, the bottom wall 140 is matched with the bottom face 103 of the handbag 10, and the two bag body limiting components 150 are respectively matched with the two first side walls 120. Thus, the molding die 100 can support each surface of the handbag 10 by using the two first side walls 120, the two second side walls 130, and the bottom wall 140, so as to provide shape support for the bag body during the process of the sheet material 20 being molded into the handbag 10, and each bag body limiting component 150 and a corresponding first side wall 120 jointly limit the front face 101 of a corresponding handbag 10.

[0065] Furthermore, for the handbag 10 of the above structure, before the handbag 10 is formed into a bag body from the sheet 20, the two ends of the sheet 20 in the length direction 201 are pre-folded inward to form a bag opening fold 104 (see Figure 4 Then, in the process of forming the handbag 10 from the sheet 20 into the bag body, the bag body side 102 and the folded edge 104 are sealed at the same time.

[0066] Take the handbag 10 made of a non-deformable material, such as a paper bag, as an example, in order to avoid the poor flatness of the connection of the bag fold 104 and the influence of the bag fold 104 on the structural reinforcement performance of the handbag 10.

[0067] In one embodiment of the present invention, at least one of the two first side walls 120 is connected to the corresponding side of the mold body 110 in a reciprocating manner along the height direction 111 of the mold body 110. When in use, the two front faces 101 of the handbag 10 are fixed to the corresponding first side walls 120 by the two bag body stopper assemblies 150 (such as Figure 8 and Fig. 9 When the two first side walls 120 move relative to each other, the two front faces 101 of the handbag 10 can be misaligned in the height direction 111 of the mold body 110 (as shown in FIG. Fig.10 and Fig.11 As shown in the state), the two side faces 102 adjacent to the two front faces 101 can be partially misaligned, and the connecting portion of the bag opening fold 104 of the handbag 10 is also misaligned up and down. When the two first side walls 120 are reset, the connecting portion of the misaligned bag opening fold 104 can be plugged into each other (as shown in the state shown in the state). Fig.13 The state shown in FIG. 1 is shown in FIG. 1 ), and then the corresponding operation of the pressing assembly 600 and other structures can realize the simultaneous molding of the bag body and the bag opening fold 104 of the handbag 10 (such as Figure 1The state shown in the figure), and the connection of the bag opening fold 104 is sealed by plugging, which can not only avoid the poor flatness of the connection of the bag opening fold 104 of the handbag 10 affecting the aesthetics, but also is more conducive to the bag opening fold 104 to strengthen the bag body structure of the handbag 10.

[0068] In the process of forming the handbag 10 using the above-mentioned forming mold 100, the production of the entire handbag 10 can be completed after the forming process is completed, and there is no need to set up a separate bag mouth folding device to perform other operations on the formed bag body. This not only simplifies the production process of the handbag 10 and improves the production efficiency of the handbag 10; it also avoids the probability of the bag body of the handbag 10 being damaged by being pulled by other operations after forming.

[0069] Therefore, when the handbag 10 is manufactured by using the molding die 100 provided by this embodiment of the present invention, the handbag 10 with good aesthetics and good bag structure stability can be manufactured with high efficiency and high yield.

[0070] The specific structure and working principle of the forming mold 100 of the handbag provided by the present invention are further described in detail below:

[0071] Regarding the mold body 110 of the molding mold 100:

[0072] See also Figure 1 , Figure 2 , Fig.14 The mold body 110 is the main structure of the entire molding mold 100, and provides structural support for the two first side walls 120, the two second side walls 130, the bottom wall 140, and the two bag body limiting components 150. The structure of the mold body 110 is not limited, and can be a frame structure, such as a mold body 110 formed by splicing horizontal beams and vertical beams. The mold body 110 is made of a material with high hardness, such as steel.

[0073] It should be understood that the two first side walls 120, the two second side walls 130, and the bottom wall 140 can be detachably connected to the mold body 110, for example, they can be connected by bolts. When making the handbag 10, corresponding to handbags 10 of different specifications, only the corresponding side walls can be replaced to adjust the overall size of the forming mold 100. Of course, a special mold changing system can also be set to replace the entire forming mold 100.

[0074] Regarding the two first side walls 120 of the molding die 100:

[0075] See also Figure 1 , Figure 2 , Fig.14The two first side walls 120 are respectively adapted to the two front sides 101 of the handbag 10 and are used to support the two front sides 101 of the handbag 10 . That is, during the molding process of the handbag 10 , the two front sides 101 of the handbag 10 are respectively wrapped around the corresponding first side walls 120 .

[0076] The structures of the two first side walls 120 are not limited, for example, they can both be set as flat plate structures, which can ensure that the surface of the handbag 10 is flat and smooth, help reduce the shape distortion of the handbag 10 caused by mold deformation, and thus improve the molding quality of the handbag 10.

[0077] The connection method between the two first side walls 120 and the mold body 110 is not limited to a specific one.

[0078] In one embodiment, one of the two first side walls 120 is movably connected to the mold body 110 , and the other first side wall 120 is fixed to the mold body 110 as a whole.

[0079] In this embodiment, a feasible solution may be that a first side wall 120 drives a front side 101 of the handbag 10 to first move downward along the height of the mold body 110 and then move upward, so that the bag opening folded edges 104 of the two side faces 102 of the handbag 10 adjacent to one front side 101 are respectively inserted into the bag opening folded edges 104 of the two side faces 102 adjacent to the other front side 101.

[0080] For a clearer introduction to this approach, see Figure 3 and, Figure 6 , Figure 8 , Fig.11 , it can be noted that one front face 101 (referred to as the "first front face 1011"), and the two first side walls 120, the first front face 1011 and the right first side wall 1201 (see Figure 3 ) corresponds to another front surface 101 (referred to as the "second front surface 1012"), the second front surface 1012 and the left first side wall 1202 (see Figure 3 )correspond.

[0081] In the initial state, the bag opening folds 104 of the four side surfaces 102 (two adjacent to the first front surface 1011 and two adjacent to the second front surface 1012) of the handbag 10 have not yet been plugged in (e.g. Figure 8 and Fig. 9 status shown).

[0082] When the bag opening fold 104 needs to be inserted, the first side wall 1201 on the right side drives the first front surface 1011 to move downward along the height direction 111 of the mold body 110 (such as Fig.10 and Fig.11As shown in the state shown in the figure), when the first front side 1011 drops to a certain position, the pocket fold edges 104 of the two adjacent side surfaces 102 will naturally bend inwards to prepare for subsequent insertion.

[0083] Next, the first side wall 1201 on the right side drives the first front side 1011 to move upward along the height direction 111 of the mold body 110. During this process, the pocket folds 104 of the two adjacent side surfaces 102 of the first front side 1011 are inserted into the pocket folds 104 of the two adjacent side surfaces 102 of the second front side 1012, completing the insertion (such as Fig.13 status shown).

[0084] Another feasible solution may be that a first side wall 120 drives a front side 101 of the handbag 10 to first move upward along the height of the mold body 110 and then move downward, so that the bag opening folded edges 104 of the two side sides 102 adjacent to the other front side 101 of the handbag 10 are respectively inserted into the bag opening folded edges 104 of the two side sides 102 adjacent to the one front side 101.

[0085] In order to introduce this scheme more clearly, the scheme is not shown in the figure. For ease of understanding, please refer to Figure 3 , Figure 6 , Figure 8 , Fig.11 Similarly, one of the front faces 101 (referred to as the “first front face 1011”) can be recorded. Among the two first side walls 120, the first front face 1011 corresponds to the right first side wall 1201, and the other front face 101 (referred to as the “second front face 1012”), the second front face 1012 corresponds to the left first side wall 1202.

[0086] In the initial state, the bag opening folds 104 of the four side surfaces 102 (two adjacent to the first front surface 1011 and two adjacent to the second front surface 1012 ) of the handbag 10 have not been plugged in yet.

[0087] When the pocket fold 104 needs to be inserted, contrary to the first solution, the first side wall 1201 on the right first drives the first front surface 1011 to move upward along the height direction 111 of the mold body 110. When the first front surface 1011 rises to a certain position, the pocket folds 104 of the two adjacent side surfaces 102 will also change accordingly.

[0088] Then, the first side wall 1201 on the right side drives the first front side 1011 to move downward along the height direction 111 of the mold body 110. At this time, the pocket folded edges 104 of the two adjacent side surfaces 102 of the second front side 1012 will be inserted into the pocket folded edges 104 of the two adjacent side surfaces 102 of the first front side 1011, and the connection is also completed.

[0089] In another embodiment, the two first side walls 120 are movably connected to the mold body 110 along the length direction of the mold body 110. When in use, one first side wall 120 can drive a front side 101 of the handbag 10 to move downward along the height of the mold body 110 and then move upward, and the other first side wall 120 can drive a front side 101 of the handbag 10 to move upward along the height of the mold body 110 and then move downward, so that the bag opening folded edges 104 of the two side faces 102 of the handbag 10 adjacent to one front side 101 are respectively inserted into the bag opening folded edges 104 of the two side faces 102 adjacent to the other front side 101.

[0090] In order to explain more clearly, this scheme is not shown in the figure. For ease of understanding, please refer to Figure 3 , Figure 6 , Figure 8 , Fig.11 Similarly, one of the front faces 101 (referred to as the “first front face 1011”) can be recorded. Among the two first side walls 120, the first front face 1011 corresponds to the right first side wall 1201, and the other front face 101 (referred to as the “second front face 1012”), the second front face 1012 corresponds to the left first side wall 1202.

[0091] In the initial state, the bag opening folds 104 of the four side surfaces 102 (two adjacent to the first front surface 1011 and two adjacent to the second front surface 1012 ) of the handbag 10 have not been plugged in yet.

[0092] When the pocket fold 104 needs to be plugged in, the first side wall 1201 on the right side drives the first front surface 1011 to move downward along the height direction 111 of the mold body 110, and this action causes the pocket fold 104 of the two adjacent side surfaces 102 of the first front surface 1011 to begin to bend inward (close to the mold side) to prepare for subsequent plugging. Then, the first side wall 1201 on the right side drives the first front surface 1011 to move upward.

[0093] At the same time, the first side wall 1202 on the left drives the second front surface 1012 adjacent thereto to move upward along the height direction 111 of the mold body 110. This action also causes the pocket folds 104 of the two side surfaces 102 adjacent to the second front surface 1012 to begin to change (begin to bend away from the mold side) in preparation for plugging. Then, the first side wall 1202 on the left drives the second front surface 1012 to move downward.

[0094] It should be understood that, in this embodiment, the right first side wall 1201 and the left first side wall 1202 may act simultaneously, or one may be slightly delayed compared to the other, which may be set according to actual needs.

[0095] During the reciprocating movement of the right first side wall 1201 and the left first side wall 1202 in two directions, the pocket folding edges 104 of the two adjacent side surfaces 102 of the first front surface 1011 will be inserted into the pocket folding edges 104 of the two adjacent side surfaces 102 of the second front surface 1012. In this way, the pocket of the handbag 10 is plugged in.

[0096] In this embodiment, by controlling the movement of the two first side walls 120 , the movement stroke of each first side wall 120 can be reduced, thereby improving the plugging efficiency of the bag opening fold 104 .

[0097] In the various configurations of the first side wall 120 described above, when the first side wall 120 is movably connected to the mold body 110 , it may be a sliding connection or a rolling connection.

[0098] In one possible implementation, see Fig.14 The molding die 100 further includes a guide member 170 disposed between at least one of the two first side walls 120 and the mold body 110 , and a driving member 180 for driving at least one of the two first side walls 120 to move.

[0099] Specifically, the guide member 170 is fixedly connected to the mold body 110 and is located on the inner side of the corresponding first side wall 120, and the guide member 170 extends at an inclined angle at a preset angle relative to the height direction 111 of the mold body 110. For example, in the height direction 111 of the mold body 110, the upper end of the guide member 170 is farther away from the inner wall of the corresponding first side wall 120 than the lower end.

[0100] When the first side wall 120 is connected to the mold body 110, it can be slidably connected to the guide member 170, and the driving member 180 is fixedly connected to the mold body 110 and located on one side of the guide member 170, and the driving end of the driving member 180 is transmission-connected to the first side wall 120 to drive the first side wall 120 to move along the guide member 170.

[0101] For the structure and arrangement of the guide member 170, see Fig.14 The guide member 170 may include a plurality of guide rails, for example, four guide rails are provided, and the four guide rails are evenly arranged in the plane where the inner wall surface of the first side wall 120 is located, for example, they are symmetrically arranged in pairs.

[0102] See further Fig.15 The length of each guide rail is set to: L≥H / cosA; where L is the length of the guide rail; H is the width of the folded edge 104; and A is the preset angle of inclination of the guide rail.

[0103] It should be understood that the number of guide rails is not limited to 4, but can also be 2, 3, 5 or other numbers. The preset angle of inclination of the guide rails is not limited, for example, it can be set between 10° and 30°, and the width of the bag fold 104 can be determined according to the specific bag type of the handbag 10.

[0104] Further, when the first side wall 120 is connected to the guide rail, a slider may be provided on the inner wall surface of the first side wall 120 , and the first side wall 120 is slidably connected to the guide rail via the slider.

[0105] The structure and number of the driving component 180 are not limited. For example, the driving component 180 can be set as a cylinder, an electric push rod, etc., and the driving component 180 can be set to two. The two driving components 180 can be distributed on both sides of the first side wall 120 in its width direction, which is conducive to the stability of the first side wall 120 when moving.

[0106] Regarding the control of the driving member 180, the driving member 180 may have its own control element, see Figure 2 and Figure 3 Alternatively, an electromagnetic valve 191 may be provided on the mold body 110. When the driving component 180 is provided as an electric cylinder or an electric push rod, the electromagnetic valve 191 is electrically connected to the electric cylinder or the electric push rod. When the electromagnetic valve 191 controls the push rod of the electric cylinder or the electric push rod to extend, the first side wall 120 may be driven to move upward or downward, so as to achieve the misalignment of the bag opening folding edges 104 on both sides of the side 102 of the handbag 10; when the electromagnetic valve 191 controls the push rod of the electric cylinder or the electric push rod to retract, the first side wall 120 may be driven to reset, so as to achieve the connection between the bag opening folding edges 104 on both sides of the side 102 of the handbag 10. In this way, the moving distance of the first side wall 120 may be accurately controlled, thereby further improving the stability of the connection of the folding edges 104.

[0107] In this embodiment, by providing the guide member 170 , precise guidance is provided for the movement of the first side wall 120 , thereby ensuring the stability and accuracy of the first side wall 120 during the movement, thereby improving the accuracy of the insertion of the folded edge 104 .

[0108] In addition, in the height direction 111 of the mold body 110, the guide member 170 is designed to be inclined, that is, the upper end of the guide member 170 is farther away from the inner wall of the corresponding first side wall 120 than the lower end. This design helps to insert the folded edges 104 on both sides of the side 102 with a larger area first, and then gradually insert them into the required positions during the plug-in process. This is more conducive to the success rate of the plug-in of the folded edges 104 on both sides of the side 102.

[0109] In the various configurations of the first side wall 120 described above, when the first side wall 120 is fixedly connected to the mold body 110 , the first side wall 120 and the mold body 110 may be fixedly connected by bolts.

[0110] Specifically, the first side wall 120 may include a plurality of strip plates, which are bolted to the edge of the mold body 110 in its width direction, or are bolted to the four sides of the mold body 110, and the first side wall 120 is formed by overlapping a plurality of strip plates.

[0111] Based on the structure and arrangement of the first side wall 120 described above, the structure and arrangement of the two bag body limiting components 150 are described below:

[0112] Among the two bag body limiting components 150, the bag body limiting component 150 adapted to the first side wall 120 among the two first side walls 120 that can reciprocate relative to the mold body 110 includes a grabbing component, which is fixedly arranged on the outer wall surface of the corresponding first side wall 120; the bag body limiting component 150 adapted to the first side wall 120 among the two first side walls 120 that is fixedly arranged on the mold body 110 includes a pressing component, which is detachably pressed against the outer wall surface of the first side wall 120 along the thickness direction 112 of the mold body 110.

[0113] It should be understood that if the two first side walls 120 are connected to the corresponding side portions of the mold body 110 so as to be reciprocatably movable along the height direction 111 of the mold body 110 , the two bag limiting assemblies 150 can both be configured as gripping components.

[0114] If one first side wall 120 is reciprocatably connected to the corresponding side of the mold body 110 along the height direction 111 of the mold body 110, and the other is fixedly set on the corresponding side of the mold body 110, then one of the two bag body limiting components 150 is set as a grabbing component and the other is a pressing component.

[0115] By setting a grabbing component on the movable first side wall 120, the grabbing component can not only fix the handbag 10, but also move synchronously with the first side wall 120, so that the bag mouth fold 104 of the handbag 10 can be plugged in while simplifying the structure of the molding mold 100 as much as possible.

[0116] Of course, in the above two cases, both bag body limiting components 150 can also be set as pressing components, wherein the pressing component corresponding to the movably arranged first side wall 120 is arranged on one side of the first side wall 120 through a lifting component, that is, the first side wall 120 can move synchronously with the corresponding pressing component to achieve the fixation of the front side 101 of the handbag 10 on the movable first side wall 120.

[0117] The structure of the lifting component is not limited, for example, it can be a lifting motor, a lifting cylinder, etc.

[0118] The specific structure and arrangement of the gripping component are not limited, such as a suction cup, a clamping claw, etc.

[0119] In one embodiment, see Figure 2 and Figure 3 The grabbing component includes a plurality of suction cups (see the structure shown in 150), and a plurality of suction cup mounting holes are formed on the corresponding first side wall 120. The plurality of suction cup mounting holes are evenly distributed throughout the first side wall 120, and each suction cup is respectively arranged in the corresponding suction cup mounting hole, and the suction nozzle edge of the suction cup is flush with the outer wall surface of the corresponding first side wall 120, and the suction cup is connected to the vacuum generator pipeline.

[0120] There is no limit to the number of suction cups that can be set, such as 4, 5, or any other number.

[0121] Furthermore, the suction cup is extendably arranged in the suction cup mounting hole. For example, the suction cup can be extendably arranged on the hole wall of the suction cup mounting hole by means of an electric telescopic rod. When the molding mold 100 moves from top to bottom to the front side 101 of the bag body close to the first side wall 120, the suction cup extends, sucks the front side 101 of the bag body on the corresponding side and retracts to the suction cup mounting hole, so that the front side 101 of the bag body is attached to the outer wall surface of the first side wall 120.

[0122] In this embodiment, the operation of the suction cup grabbing component is relatively simple, and the handbag 10 can be grabbed and released quickly and accurately, which can shorten the production cycle. Multiple suction cups are evenly distributed throughout the first side wall 120, which can ensure that a uniform adsorption force is provided when grabbing the front 101 of the handbag 10, thereby preventing the handbag 10 from being misplaced or deformed during the molding process. The edge of the suction cup's nozzle is flush with the outer wall surface of the first side wall 120, so that the grabbing component is more stable when contacting the handbag 10, reducing damage caused by friction or collision. In addition, the suction cup will not cause scratches or indentations on the surface of the handbag 10 when grabbing it, which can protect the integrity and aesthetics of the handbag 10.

[0123] In another embodiment, not shown in the figure, the gripping component includes a clamping member arranged at the top edge of the corresponding first side wall 120. The clamping member can be an electric clamp, a pneumatic clamp, a clamp, etc. When the front side 101 of the handbag 10 is close to the corresponding first side wall 120, the clamping member and the first side wall 120 jointly clamp the corresponding front side 101 of the handbag 10.

[0124] In this embodiment, the clamping member can be arranged on the top edge of the first side wall 120. When the molding mold 100 moves from top to bottom to the front side 101 of the bag body close to the first side wall 120, the electric clamp automatically clamps the upper edge of the front side 101 of the handbag 10 to fix it relatively to the first side wall 120. This design can ensure that the handbag 10 is accurately clamped and positioned during the molding process.

[0125] In addition, the clamping member has good adjustability, which can not only adapt to the handbags 10 of different thicknesses and materials, but also achieve the limitation of the corresponding front side 101 of the handbag 10 in various directions, and the probability of falling off is low.

[0126] The specific structure and arrangement of the pressing component are not limited, such as a pressing plate, a crawler track, etc.

[0127] In one embodiment, the pressing component includes a flexible pressing member and a movable seat. The flexible pressing member can be a rubber plate. The movable seat can be movably set on the frame along the thickness direction 112 of the mold body 110. The flexible pressing member is fixedly connected to the movable seat and extends toward the corresponding first side wall 120. When the front side 101 of the handbag 10 approaches the corresponding first side wall 120, the movable seat moves closer along the thickness direction 112 of the mold body 110, so that the flexible pressing member squeezes the front side 101 of the handbag 10 and is fixed to the corresponding first side wall 120.

[0128] When the bag body of the handbag 10 is formed by using such a forming mold 100, when the forming mold 100 descends to the lowest position, the sheet 20 is bent toward the forming mold 100 under the limiting action of the surrounding components of the forming mold 100 (for example, the inner wall surface of the receiving area of ​​the forming mold), and the front face 101 of the handbag 10 is close to the first side wall 120. Further, in subsequent steps, other components beside the forming mold 100 (for example, a flexible pressing member) can be used to squeeze the front face 101 of the handbag 10, so that the front face 101 of the handbag 10 is completely fitted with the first side wall 120.

[0129] Further, based on the structure and configuration of the first side wall 120, see Figure 2 and Figure 3 In the embodiment of the present invention, at least one of the two first side walls 120 is further provided with a vent hole 121. The vent holes 121 may be provided on both first side walls 120, or may be provided on one of the first side walls 120. The vent holes 121 may be a plurality of strip holes formed on the first side wall 120, for example, 3, 4, or 5 strip holes may be provided.

[0130] The ventilation holes 121 can be provided to prevent a vacuum from being formed between the front surface 101 of the handbag 10 and the outer wall surface of the first side wall 120, thereby preventing interference with subsequent bag removal.

[0131] Regarding the two second side walls 130 of the molding die 100:

[0132] See also Figure 2 and Figure 3 The two second side walls 130 are respectively adapted to the two side surfaces 102 of the handbag 10 and are used to support the two side surfaces 102 of the handbag 10 . That is, during the molding process of the handbag 10 , the two side surfaces 102 of the handbag 10 are respectively wrapped around the corresponding second side walls 130 .

[0133] The structures of the two second side walls 130 are not limited, for example, they can both be set as flat plate structures, which can ensure that the surface of the handbag 10 is flat and smooth, help reduce the shape distortion of the handbag 10 caused by mold deformation, and thus improve the molding quality of the handbag 10.

[0134] There is no specific requirement for the connection method between the two second side walls 130 and the mold body 110 . For example, the two second side walls 130 can be detachably connected to the mold body 110 by bolts, so as to be fixed integrally with the mold body 110 .

[0135] Furthermore, in the molding mold 100 provided by the present invention, in order to improve the success rate of the insertion of the bag opening folded edge 104, the molding mold 100 provided by the present invention also includes two folded edge opening components 160 respectively arranged at the corresponding positions of the two second side walls 130. When the bag opening folded edge 104 of the sheet material 20 that is pre-folded inward at both ends in the length direction is pressed close to the second side wall 130, the folded edge opening component 160 can make the bag opening folded edge 104 of the two side surfaces 102 of the handbag 10 that is farther away from the second side wall 130 open.

[0136] With such a structure, when the sheet 20 of the handbag 10 is pre-folded 104, even if the opening angle of the folded edge 104 is small, or when other factors such as static electricity cause the folded edge 104 to fit the bag body, when the sheet 20 is pressed close to the second side wall 130, the folded edge opening component 160 can also accurately open the folded edge 104 to be inserted. At least one of the two first side walls 120 drives at least one front side 101 of the handbag 10, and links at least one of the two side surfaces 102 of the handbag 10 to move back and forth relative to the mold body 110, so that the bag mouth folded edge 104 of the other side surface 102 of the handbag 10 can be inserted into the bag mouth folded edge 104 of one side, thereby realizing the smooth insertion of the two folded edges 104, which can greatly improve the success rate of the insertion of the bag mouth folded edge 104 and further improve the yield rate of the handbag 10.

[0137] The structure and arrangement of the two folding opening components 160 are further described in detail below.

[0138] In one embodiment, both hem opening components 160 include suction members ( Figure 2 and Figure 3 The structure shown in 160 in FIG. 1 ), wherein the air suction component is arranged on the second side wall 130, and the air suction component corresponds to the bag opening fold 104 of the side surface 102 of the corresponding side of the handbag 10 in the height direction 111 of the mold body 110, and the air suction port of the air suction component is flush with the outer wall surface of the second side wall 130.

[0139] In this embodiment, the suction component can be set as a suction cup, and a corresponding mounting hole is set on the second side wall 130. The suction cup is installed in the mounting hole, and the suction port of the suction cup is flush with the outer wall surface of the second side wall 130.

[0140] During use, when the bag opening folded edge 104 of the sheet material 20 that is pre-folded inward at both ends in the length direction is pressed close to the second side wall 130, the suction component generates negative pressure (i.e., pressure lower than atmospheric pressure) through the suction port, sucking the material of the bag opening folded edge 104 so that it is closely attached to the suction port. With the continuous action of the suction force, the bag opening folded edge 104 will be gradually pulled apart, thereby achieving the purpose of opening the folded edge 104. With such a structure, when the sheet material 20 of the handbag 10 is pre-folded 104, even if the opening angle of the folded edge 104 is small, or when other factors such as static electricity cause the folded edge 104 to fit the bag body, when the sheet material 20 is pressed close to the second side wall 130, the folded edge opening component 160 can also accurately open the fold of the inserted folded edge 104, which can greatly improve the success rate of inserting the bag opening folded edge 104.

[0141] Furthermore, a vacuum generator 192 is also provided on the mold body 110 , and the vacuum generator 192 is connected to the suction component pipeline to provide negative pressure for the suction component.

[0142] Furthermore, by making the suction port of the suction cup flush with the outer wall surface of the second side wall 130, when the folded edge 104 is sucked open, the folded edge 104 can fit the outer wall surface of the second side wall 130, so that the opening angles of the folded edge 104 at various locations can be made more uniform.

[0143] In another embodiment, both folding edge opening parts 160 include a blowing component (this solution is not shown in the figure), the blowing component is provided with the second side wall 130, and the blowing component corresponds to the area below the bag opening folding edge 104 of the side surface 102 of the corresponding side of the handbag 10 in the height direction 111 of the mold body 110, and the blowing port of the blowing component is flush with the outer wall surface of the second side wall 130.

[0144] In this embodiment, the blowing member may be configured as a blowing nozzle, a corresponding mounting hole is provided on the second side wall 130, the blowing nozzle is installed in the mounting hole, and the blowing port of the blowing nozzle is flush with the outer wall surface of the second side wall 130. The blowing nozzle may be connected to an external air pump pipeline.

[0145] During use, when the bag opening folded edges 104 of the sheet material 20 which are pre-folded inward at both ends in the length direction are pressed close to the second side wall 130, Fig.12 , the air pressure blown out by the blowing nozzle first acts on the side 102 of the handbag 10, and a part of the airflow will flow along the side 102 of the handbag 10 to the bag opening side to the position of the fold 104. At this time, the tension generated by the airflow reaching the bag opening will cause the fold 104 to open, thereby achieving the purpose of opening the fold 104. With such a structure, when the sheet 20 of the handbag 10 is pre-folded 104, even if the opening angle of the fold 104 is small, or when other factors such as static electricity cause the fold 104 to fit the bag body, when the sheet 20 is pressed close to the second side wall 130, the fold opening component 160 can also accurately open the fold of the inserted fold 104, which can greatly improve the success rate of inserting the bag opening fold 104.

[0146] Furthermore, by aligning the blowing port of the blowing member with the outer wall surface of the second side wall 130 , it is possible to avoid interference of the blowing member with the side surface 102 of the handbag 10 .

[0147] Regarding the bottom wall 140 of the molding die 100:

[0148] See also Figure 2 and Figure 3 The bottom wall 140 is matched with the bottom surface 103 of the handbag 10 and is used to support the bottom surface 103 of the handbag 10 , that is, during the molding process of the handbag 10 , the bottom surface 103 of the handbag 10 is wrapped on the corresponding bottom wall 140 .

[0149] The structure of the bottom wall 140 is not limited, for example, it can be set as a flat plate structure, which can ensure that the surface of the handbag 10 is flat and smooth, and help reduce the shape distortion of the handbag 10 caused by mold deformation, thereby improving the molding quality of the handbag 10.

[0150] There is no specific requirement for the connection method between the bottom wall 140 and the mold body 110 . For example, the bottom wall 140 may be detachably connected to the mold body 110 by bolts, thereby being fixed integrally with the mold body 110 .

[0151] Furthermore, in order to achieve relative fixation between the bottom surface 103 of the handbag 10 and the bottom wall 140 , a bottom support plate may be provided below the bottom wall 140 , and upward movement of the bottom support plate may achieve relative fixation between the bottom surface 103 of the handbag 10 and the bottom wall 140 .

[0152] The molding die 100 may also include an adsorption component, which may be a suction cup. The adsorption component is disposed on the bottom wall 140 and is used to adsorb the bottom surface 103 of the handbag 10 and make the bottom surface 103 of the handbag 10 fit against the outer wall surface of the bottom wall 140, that is, the bottom surface 103 of the handbag 10 and the bottom wall 140 can be relatively fixed without providing a bottom support plate.

[0153] Based on the above structure of the molding die 100, see Fig.16 and Fig.17 The present invention also provides a forming mold 100 assembly for a handbag, the forming mold 100 assembly includes a receiving platform 200, the receiving platform 200 is formed with a forming area 210, a forming mold 100 with the above structure is arranged above the receiving platform 200 at a position corresponding to the forming area 210, and the forming mold 100 is movably arranged above the forming area 210 in a vertical direction,

[0154] Furthermore, the molding mold 100 assembly also includes a side insertion component 300 that is arranged below the receiving platform 200 and is movably arranged along the thickness direction 112 of the mold body 110. When the molding mold 100 moves from top to bottom until the sheet 20 is bent toward the two first side walls 120 of the mold body 110, the side insertion component 300 moves toward the mold body 110 to press the opposite sides of the two side surfaces 102 of the handbag 10 to bend toward the second side wall 130. The side insertion component 300 can be a side insertion plate that is movably arranged along the thickness direction 112 of the mold body 110.

[0155] Furthermore, the molding die 100 assembly also includes a lifting assembly 400 disposed above the receiving platform 200, a connecting plate 113 is fixedly disposed above the mold body 110, and the mold body 110 is connected to the driving end of the lifting assembly 400 through the connecting plate 113. The lifting assembly 400 may include a lifting motor and a transmission component, and the transmission component may be a transmission belt, one end of the transmission belt is connected to the driving shaft of the lifting motor through a pulley, and the other end of the transmission belt is connected to the connecting plate 113 through a pulley, so that the lifting motor is linked to the molding die 100 to move in the vertical direction through the transmission belt.

[0156] In use, for example, when the sheet 20 is conveyed to the forming area 210 (see Figure 5 and Fig.16 The lifting motor drives the forming mold 100 to descend, so that the two front sides 101 of the sheet 20 are gradually bent toward the outer periphery of the forming mold 100 under the joint action of the forming mold 100 and the receiving platform 200 (see Figure 6 Then, the side plug assembly 300 is used to push the two side surfaces 102 to bend toward the two second side walls 130 (see Fig. 9 status shown).

[0157] It should be understood that the side plug-in assembly 300 pushes the two side surfaces 102 to bend toward the two second side walls 130 respectively, and makes the connection positions of the two side surfaces 102 overlap, and then controls the grasping component or the pressing component to fix the two front surfaces 101 to the outer wall surface of the first side wall 120 respectively. Based on the design of the above-mentioned molding die 100, it can be known that a grasping component, such as a suction cup, can be provided on the right first side wall 1201, and the first front surface 1011 can be fixed to the right first side wall 1201 by the grasping component; a pressing component can be provided on one side of the left first side wall 1202, and the pressing component can be controlled to move toward the molding die 100 to fix the second front surface 1012 to the left first side wall 1202 (such as Figure 7 status shown).

[0158] In this embodiment, the molding die assembly further includes a bag removal assembly 500. Specifically, see Fig.16 and Fig.17 The bag stripping assembly 500 includes a bag stripping belt 510 facing the mold body 110, and the bag stripping belt 510 can move along the thickness direction 112 of the mold body 110. After the two side surfaces 102 are pushed to bend toward the two second side walls 130 respectively by the side insertion assembly 300, the bag stripping belt 510 of the bag stripping assembly 500 can be controlled to approach the first side wall 120, and the bag stripping belt 510 of the bag stripping assembly 500 presses and fixes the front side 101 of the handbag 10 between it and the first side wall 120.

[0159] The molding mold 100 assembly provided by the present invention adopts the molding mold 100 with the above structure, so that when the molding mold assembly is realizing the molding process of the handbag 10, the bag body and the bag mouth folding edge 104 of the handbag 10 can be formed simultaneously, which not only makes the function of the molding mold 10 assembly more diversified, but also greatly improves the production efficiency of the handbag 10.
