Description

Technical Field

[0001] The utility model relates to the field of handbag production, in particular to a handbag forming device. Background Art

[0002] Handbags have become an indispensable and common tool in modern society. Due to the high practicality and portability of handbags, people have gradually put forward various requirements for the manufacturing of handbags. The handles of handbags are usually set at the bag opening, and are often fixed to the edge of the bag opening by bonding or fixings. However, since the strength of the bag opening itself is relatively low, the strength of the connection between the bag opening and the handle is also relatively low, and users are often troubled by the damage of the connection between the bag opening and the handle.

[0003] To this end, in the prior art, during the production process of handbags, a forming mold is usually used to first press a substrate into a bag body, and then a separate closing machine is used to fold the bag opening inward, so that a bag opening fold edge is formed around the bag opening, thereby increasing the strength of the bag opening and reducing the risk of tearing the bag opening when loading and unloading items.

[0004] However, after the bag body is formed, using a mouth-folding machine to fold and press the bag mouth of the bag body will increase the production process of the handbag, resulting in the need to transfer the handbag to the mouth-folding machine for folding after forming, which greatly delays the production rate of the handbag; on the other hand, after the handbag is pressed into a bag body by the forming mold, it is usually squeezed into a folded state after being separated from the forming mold, so as to facilitate subsequent stacking and storage. When the bag body is folded by the mouth-folding machine, the bag body needs to be in an expanded state again so that part of the base material of the bag mouth can be folded inward, which is not convenient for subsequent storage and transportation. Utility Model Content

[0005] The purpose of the utility model is to solve the technical problem that in the prior art, a bag mouth is folded and pressed by a bag mouth machine after the bag body is formed. On the one hand, this increases the production process of handbags and greatly delays the production rate of handbags. On the other hand, after the handbag is pressed into a bag body by a forming mold, it is usually squeezed into a folded state after being separated from the forming mold, so as to facilitate subsequent stacking and storage. When the bag body is folded by the bag mouth machine, the bag body needs to be in an expanded state again so that part of the base material of the bag mouth can be folded inward, which is not convenient for subsequent storage and transportation.

[0006] In order to solve the above technical problems, the embodiment of the utility model discloses a handbag forming device, which can directly press and form a substrate with a pre-folded edge, and then clamp the top through a top clamping component and move back and forth along the height direction, so that the edges at the bag opening are inserted into each other at the overlapping position, thereby forming a continuous edge surrounding the bag opening. That is, in the handbag forming process, the edge of the bag opening is directly processed and formed, and there is no need for subsequent processing through a separate closing machine.

[0007] Specifically, the handbag forming device comprises a mold body, and the top of the mold body is transmission-connected to the mold driving member.

[0008] The mold body includes a pair of first support parts arranged at intervals along the width direction of the mold body and a pair of second support parts arranged at intervals along the length direction of the mold body, and the two side edges of each first support part in the length direction are respectively connected with the edges of the corresponding second support part in the width direction to form edges; and a top clamping component is provided on at least one side in the width direction of the mold body, and the top clamping component can reciprocate relative to the mold body on the corresponding side along the height direction of the mold body.

[0009] The mold body presses the substrate below, and the substrate is bent to surround the mold body to form a bag body of the handbag. The two ends of the bag body overlap the outer surface parts of the corresponding second support parts, and the edge of the bag mouth of the bag body has a pre-folded edge.

[0010] Furthermore, each top clamping component clamps the top of the folded edge on the corresponding side and reciprocates along the height direction, so that the folded edges of the bag body at each second supporting portion are plugged into each other at overlapping positions.

[0011] During use, the top of the mold body of the handbag forming device is driven by the mold driving member and moves along the height direction of the mold body, thereby pressing the substrate below. It should be noted that before the substrate is pressed by the mold body, the ends of the substrate on both sides of the width direction of the mold body are pre-folded inward to form hems. Viewed from the height direction of the mold body, the substrate is squeezed and bent by the mold body on both sides of the width direction of the mold body to surround a pair of first support parts of the mold body; further, the substrate is squeezed and bent by auxiliary components (such as side plug components) on both sides of the length direction of the mold body to surround a pair of second support parts of the mold body. At this time, the two ends of the bag body overlap at the outer surface of the corresponding second support part, and similarly, the hems also overlap at the corresponding positions on the outer surface of the second support part.

[0012] Furthermore, each top clamping component clamps the top of the folded edge on the corresponding side and moves back and forth in the height direction, so that the folded edge of each second support portion of the bag body is staggered in the overlapping position and then plugged in, thereby forming a continuous folded edge around the bag opening.

[0013] This handbag forming device forms a continuous folded edge around the bag mouth while pressing the base material to form the bag body. There is no need to set up a separate mouth-wrapping machine to press the folded edge of the bag mouth, which simplifies the production process of the handbag, improves the production rate of the handbag, and saves the space occupied by the handbag forming equipment. Moreover, after the handbag is produced and formed, it can be folded directly so that the handbag is in a folded state, which is convenient for the subsequent stacking and storage of the handbag.

[0014] Furthermore, during the process of inserting the folded edge of each second support portion of the bag body in the overlapping position, since the top clamping component is directly clamped on the top of the folded edge, compared with acting on other positions on the substrate (such as the substrate located on the outer surface of the first support portion), the clamping stability is improved, ensuring that the folded edge can move along a predetermined trajectory, thereby improving the success rate of the folded edge insertion.

[0015] Further, in one embodiment, each top clamping component includes a clamping head, and when viewed along the height direction, the end of the clamping head extends out of the outer surface of the first supporting portion on the corresponding side of the mold body, and the top clamping component clamps the folded edge through the clamping head.

[0016] Furthermore, in one embodiment, the handbag forming device further includes a lifting drive component, and each clamping head is connected to the lifting drive component via a mounting portion.

[0017] Specifically, the lifting drive component is located in the internal cavity of the mold body, and the mounting portion is located in the internal cavity of the mold body, so that the space in the mold body is reasonably utilized and the external space occupied by the handbag forming device is not increased. In addition, the pair of first supporting portions and the pair of second supporting portions of the mold body can protect the components arranged in the internal cavity, so as to prevent the lifting drive component and the mounting portion from being damaged by other components.

[0018] Of course, in another embodiment, the lifting drive component is located on a frame outside the mold body, and the mounting part is located on a frame outside the mold body. Even if the lifting drive component fails or the mounting part is damaged, it can be repaired or replaced without disassembling the structure of the mold body.

[0019] Of course, when the lifting and driving component is located on a frame outside the mold body, the mounting portion may also be located in the internal cavity of the mold body.

[0020] Furthermore, in one embodiment, the handbag forming device further comprises a lifting guide component extending in the height direction, and the mounting portion can be relatively slidably disposed on the lifting guide component.

[0021] Among them, the clamping head of each top clamping component clamps the top of the folded edge on the corresponding side, and the lifting drive component drives the clamping head to move along the lifting guide component in the opposite direction relative to the folded edge on the other side, so that the bag body forms a height difference at the overlapping position at the folded edge end of each second support part.

[0022] By adopting the above technical solution, the lifting guide component can guide the movement of the clamping head, ensuring that each clamping head moves along the height direction of the mold body after clamping the corresponding folded edge, so that the folded edges at both ends of the bag body form a height difference in the height direction of the mold body, thereby improving the success rate and accuracy of the insertion.

[0023] Further, in one embodiment, each clamping head includes a base, a clamping block movably disposed on the base, and a clamping drive member. When viewed along the height direction, the clamping block is located outside the outer surface of the first support portion on the corresponding side of the mold body, and the clamping drive member is disposed on the mounting portion.

[0024] Furthermore, a clamping opening opened toward the top of the folded edge is formed between the base and the clamping block, and the clamping driving member can drive the clamping block to move back and forth relative to the base to open or close the clamping opening.

[0025] Before clamping the corresponding folded edge, the clamping head needs to make the top of the fold enter between the base and the clamping block from the clamping opening, or the lifting drive component drives the clamping head to move along the lifting guide component so that the base and the clamping block move toward the top of the folded edge and enter between the base and the clamping block from the clamping opening. Then, the clamping drive drives the clamping block to move toward the base, thereby closing the clamping opening and firmly clamping the top of the folded edge. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In the prior art, after the bag body is formed, a bag-opening machine is used to fold and press the bag mouth of the bag body. On the one hand, this will increase the production process of the handbag and greatly delay the production rate of the handbag; on the other hand, when the bag body is folded by the bag-opening machine, the bag body needs to be put into an unfolded state again so that part of the base material of the bag mouth can be folded inward, which is not convenient for subsequent storage and transportation.

[0044] To this end, the utility model discloses a handbag forming device, which can directly press and form a substrate with a pre-folded folded edge, and then clamp the top through a top clamping component and move back and forth along the height direction, so that the folded edges at the bag opening are inserted into each other at overlapping positions, thereby forming a folded edge that continuously surrounds the bag opening. That is, in the handbag forming process, the folded edge of the bag opening is directly processed and formed, and there is no need for subsequent processing through a separate closing machine.

[0045] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0046] like Figure 1 As shown, an embodiment of the utility model provides a handbag forming device 10, the top of the mold body 100 is transmission-connected to the mold driving component, and the mold driving component is used to drive the mold body 100 to press the substrate below, which can be a driving motor and a connected transmission structure commonly used in the forming equipment in the field, and this embodiment does not make specific limitations on this.

[0047] Specifically, the mold body 100 includes a pair of first support portions 110 spaced apart along the width direction X of the mold body 100, and a pair of second support portions 120 spaced apart along the length direction Y of the mold body 100, and the two side edges of each first support portion 110 in the length direction Y are respectively connected to the edges of the corresponding second support portion 120 in the width direction X to form edges.

[0048] Specifically, in one embodiment, the pair of first support portions 110 is configured as a pair of first side walls 111 , and the pair of second support portions 120 is configured as a pair of second side walls 121 .

[0049] When viewed along the height direction Z of the mold body 100 , the contour formed by the pair of first side walls 111 and the pair of second side walls 121 matches the cross-sectional outer shape of the handbag.

[0050] Further, in one embodiment, a pair of first side walls 111 and a pair of second side walls 121 are provided with a top wall 130 at the upper end along the height direction Z, and a bottom wall 140 is provided at the lower end along the height direction Z. When viewed along the height direction Z, the contours of the top wall 130 and the bottom wall 140 are adapted to the contours formed by the pair of first side walls 111 and the pair of second side walls 121.

[0051] The mold body 100 is connected to the mold driving member through the connecting member 150 on the top wall 130. When the mold body 100 is driven by the mold driving member to press the substrate below, it is mainly pressed through the bottom wall 140, so that the middle part of the substrate that can be pressed (that is, the bottom surface of the bag body) remains flat.

[0052] In another alternative embodiment, a pair of first support parts 110 include two groups of first support rod groups spaced apart along the width direction X of the mold body 100, each first support rod group spaced apart along the length direction Y of the mold body 100, and a plurality of first support rods extending along the height direction Z are spaced apart, and a pair of second support parts 120 include two groups of second support rod groups spaced apart along the length direction Y of the mold body 100, each second support rod group spaced apart along the width direction X of the mold body 100, and a plurality of second support rods extending along the height direction Z are spaced apart, and when the substrate below is pressed and bent by the mold body 100, the above-mentioned first support rod group and second support rod group can also play a supporting role for the bent substrate. Of course, the specific structures of the first support part 110 and the second support part 120 can be designed according to actual conditions and specific needs as long as they meet the supporting role for the substrate, and those skilled in the art can design them according to actual conditions and specific needs, and this embodiment does not specifically limit this.

[0053] Furthermore, the handbag forming device 10 provided in this embodiment is provided with a top clamping component 200 on at least one side of the width direction X of the mold body 100, and the top clamping component 200 can reciprocate along the height direction Z of the mold body 100 on the corresponding side relative to the mold body 100.

[0054] During use, the top of the mold body 100 of the handbag forming device 10 is driven by the mold driving member and moves along the height direction Z of the mold body 100, thereby pressing the substrate below. It should be noted that before the substrate is pressed by the mold body 100, its ends on both sides of the width direction X of the mold body 100 are folded inward in advance to form folded edges. Viewed along the height direction Z of the mold body 100, the substrate is squeezed and bent by the mold body 100 on both sides in the width direction X of the mold body 100 to surround a pair of first support parts 110 of the mold body 100; further, the substrate is squeezed and bent along the edges by auxiliary components (such as side insertion components) on both sides in the length direction Y of the mold body 100 to surround a pair of second support parts 120 of the mold body 100. At this time, the two ends of the bag body overlap partially on the outer surface of the corresponding second support part 120, and similarly, the folded edges also overlap at the corresponding positions on the outer surface of the second support part 120; further, each top clamping component 200 clamps the top of the folded edge on the corresponding side and moves back and forth along the height direction Z, so that the folded edges of the bag body at each second support part 120 are staggered at the overlapping position (such as Figure 2 and Figure 3 It should be noted that the specific structure of the side plug-in component may be that the plate-shaped side plug-in component is driven by the side plug-in driving component and pushes the substrate to bend. Those skilled in the art may design it according to actual conditions and specific needs, and this embodiment does not make any specific limitation on this.

[0055] In one embodiment, a top clamping component 200 is provided on one side of the width direction X of the mold body 100, and no top clamping component 200 is provided on the other side. During the plug-in process, the top clamping component 200 clamps the top of the folded edge on the corresponding side, and then moves downward along the height direction Z so that the top of the clamped folded edge is lower than the lower edge of the other folded edge, and then moves upward along the height direction Z so that the top of the clamped folded edge is inserted into the other folded edge, so that the folded edges at the bag opening are plugged into each other in the overlapping position.

[0056] In order to make the folded edge better plug-in, a blowing hole (not shown in the figure) penetrating the second support part 120 is also formed on the top of the second support part 120, and the blowing hole is connected to the external blowing equipment through a pipeline arranged in the mold body 100.

[0057] Furthermore, in the height direction Z of the mold body 100 , the blowing holes are lower than the lower edge of the folded edge on the corresponding side.

[0058] Specifically, taking the second support portion 120 as the second side wall 121 as an example, during the plug-in process, the top clamping component 200 clamps the top of the folded edge on the corresponding side, and then moves downward along the height direction Z, so that the top of the clamped folded edge is lower than the lower edge of the other folded edge. At this time, the blowing holes on the second side wall 121 blow air toward the substrate on the outer surface, and the airflow is blocked by the substrate and diverted around. Since the blowing holes are lower than the lower edge of the folded edge on the corresponding side, part of the gas will be blown into the space between the inner folded edge and the substrate, thereby causing the folded edge to open, making it easier for the folded edge on the other side to be inserted from below. Regarding the specific number and layout of the blowing holes, those skilled in the art can design them according to actual conditions and specific needs, and this embodiment does not make specific limitations on this.

[0059] In another alternative embodiment, top clamping components 200 are provided on both sides of the width direction X of the mold body 100. During the plug-in process, the top clamping component 200 on one side clamps the top of the corresponding folded edge and moves downward along the height direction Z, and the top clamping component 200 on the other side clamps the top of the corresponding folded edge and moves upward along the height direction Z until the top of the folded edge on one side is lower than the lower edge of the folded edge on the other side, and then the top clamping components 200 on both sides clamp the top of the corresponding folded edge and reset it, so that the folded edge on one side is inserted into the folded edge on the other side.

[0060] This handbag forming device 10 forms a continuous folded edge around the bag mouth while pressing the base material to form the bag body. There is no need to set up a separate mouth-wrapping machine to press the folded edge of the bag mouth, which simplifies the production process of the handbag, improves the production rate of the handbag, and saves the space occupied by the handbag forming equipment. Moreover, after the handbag is produced and formed, it can be folded directly so that the handbag is in a folded state, which is convenient for the subsequent stacking and storage of the handbag.

[0061] Furthermore, during the process of inserting the folded edge of each second support portion 120 of the bag body in the overlapping position, since the top clamping component 200 is directly clamped on the top of the folded edge, compared with acting on other positions on the substrate (such as the substrate located on the outer surface of the first support portion 110), the clamping stability is improved, ensuring that the folded edge moves along a predetermined trajectory, thereby improving the success rate of the folded edge insertion.

[0062] It should be noted that the handbag to be produced by this handbag forming device 10 refers to an open portable container, which can be made of a substrate such as kraft paper, plastic, degradable corn starch and bamboo fiber. At the same time, the mouth of the handbag can have a handle or an elliptical notch for easy gripping. Technical personnel in this field can design it according to actual conditions and specific needs, and the utility model does not make specific limitations on this.

[0063] like Figure 4 As shown, in one embodiment, each top clamping component 200 includes a clamping head 210. When viewed along the height direction Z, the end of the clamping head 210 extends out of the outer surface of the first support portion 110 on the corresponding side of the mold body 100, and the top clamping component 200 clamps the top of the corresponding folded edge through the clamping head 210.

[0064] Furthermore, in order to realize the automatic hem plugging, the handbag forming device 10 further includes a lifting driving component 300. Taking the top clamping component 200 disposed on one side of the width direction X of the mold body 100 as an example, each top clamping component 200 includes a clamping head 210. When viewed along the height direction Z, the end of the clamping head 210 extends out of the outer surface of the first supporting portion 110 on the corresponding side of the mold body 100. In addition, each clamping head 210 is connected to the lifting driving component 300 through the mounting portion 220.

[0065] Specifically, the lifting drive component 300 is located in the internal cavity of the mold body 100, and the mounting portion 220 is located in the internal cavity of the mold body 100, so that the space in the mold body 100 is reasonably used without increasing the external space occupied by the handbag forming device 10. In addition, the pair of first supporting portions 110 and the pair of second supporting portions 120 of the mold body 100 can protect the components disposed in the internal cavity, thereby preventing the lifting drive component 300 and the mounting portion 220 from being damaged by other components.

[0066] More specifically, taking the first support portion 110 as the first side wall 111 as an example, the lifting drive component 300 is set as the lifting cylinder 310, and the lifting cylinder 310 can be set on the first side wall 111 on the other side, without setting a component specifically for installing the lifting cylinder 310 in the internal cavity of the mold body 100.

[0067] Of course, in another embodiment, the lifting drive component 300 is located on a frame outside the mold body 100, and the mounting portion 220 is located on a frame outside the mold body 100. Even if the lifting drive component 300 fails or the mounting portion 220 is damaged, it can be repaired or replaced without disassembling the structure of the mold body 100. It should be noted that the frame outside the mold body 100 can refer to the mounting structure of the molding equipment, or the top wall 130 on the mold body 100. For example, the lifting drive component 300 is installed on the top wall 130 through a connecting rod, and when viewed along the height direction Z of the mold body 100, the lifting drive component 300 is located on one side of the mold body 100 in the width direction X. The mounting portion 220 is similar and will not be described in detail here.

[0068] Of course, when the lifting driving component 300 is located on a frame outside the mold body 100 , the mounting portion 220 may also be located in the internal cavity of the mold body 100 , and this embodiment does not make the sole limitation to this.

[0069] like Figure 4-Figure 6 As shown, in one embodiment, in order to improve the success rate of hem plug-in, the handbag forming device 10 also includes a lifting guide component 400 extending along the height direction Z, and the mounting portion 220 can be relatively slidably arranged on the lifting guide component 400. The lifting guide component 400 can guide the movement of the clamping head 210 to ensure that each clamping head 210 moves along the height direction Z of the mold body 100 after clamping the corresponding hem, so that the hems at both ends of the bag body form a height difference in the height direction Z of the mold body 100, thereby improving the success rate and accuracy of the plug-in.

[0070] Specifically, the clamping head 210 of each top clamping component 200 clamps the top of the folded edge on the corresponding side, and the lifting drive component 300 drives the clamping head 210 to move along the lifting guide component 400 in the opposite direction relative to the folded edge on the other side, so that the bag body forms a height difference at the overlapping position of the folded edge end of each second support part 120.

[0071] Furthermore, since the folded edge extends longer along the length direction Y of the mold body 100 on the first side wall 111, Figure 4 and Figure 6 As shown, in order to make the folding edge force uniform, in one embodiment, the top clamping component 200 includes two clamping heads 210 spaced apart in the length direction Y, and the two clamping heads 210 are installed side by side on the mounting portion 220 and are flush in the height direction Z.

[0072] Furthermore, the lifting guide component 400 includes two guide members 410 corresponding to the two clamping heads 210 respectively, and the two guide members 410 both extend along the height direction Z.

[0073] Specifically, in one embodiment, the two guide members 410 are configured as two vertical guide rails 411. When a pair of first support portions 110 are configured as a pair of first side walls 111, the two vertical guide rails 411 can be installed on the first side wall 111 on the side away from the clamping head 210. The mounting portion 220 is configured as a mounting plate 221. One side of the mounting plate 221 is slidably connected to the two vertical guide rails 411, and the other side is fixedly connected to the two clamping heads 210. Moreover, the mounting plate 221 is fixedly connected to the output end of the lifting drive component 300 in the middle portion in the length direction Y. The two clamping heads 210 are driven together by the lifting drive component 300 through the same mounting plate 221, thereby ensuring the lifting consistency of the two clamping heads 210.

[0074] Specifically, in one embodiment, the middle of the mounting plate 221 in the length direction Y is fixedly connected to the output end of the lifting cylinder 310. Of course, in another alternative embodiment, each clamping head 210 is provided with a corresponding mounting plate 221 and a lifting cylinder 310, and each lifting cylinder 310 drives the corresponding mounting plate 221 to link the clamping head 210 to move along the vertical guide rail 411. The present invention does not make the sole limitation to this.

[0075] Of course, when the lifting drive component 300 and the mounting part 220 are both arranged on the frame outside the mold body 100, the two vertical guide rails 411 can also be arranged on the outside of the first side wall 111 and slidably connected to the mounting part 220 from the outside, and the mounting part 220 is connected to the end of the clamping head 210 extending out of the outer surface of the mold body 100. The utility model does not make specific limitations on this.

[0076] It should be noted that, in this embodiment, the two clamping heads 210 are used to clamp the folded edges corresponding to the first side wall 111, and the extrusion deformation of the folded edges corresponding to the second side wall 121 is weak, which will not affect the folded edge plugging. Of course, the top clamping component 200 can be provided with two, three or four clamping heads 210 at intervals in the length direction Y, and the number of the guide members 410 corresponds to the number of the clamping heads 210, and the utility model does not make a sole limitation on this.

[0077] The specific structure and working principle of the clamping head 210 are described below.

[0078] like Figure 5 As shown, each clamping head 210 includes a base 211, a clamping block 212 movably disposed on the base 211, and a clamping drive member 213. When viewed along the height direction Z, the clamping block 212 is located outside the outer surface of the first support portion 110 on the corresponding side of the mold body 100, and the clamping drive member 213 is disposed on the mounting portion 220.

[0079] Furthermore, a clamping opening opened toward the top of the folded edge is formed between the base 211 and the clamping block 212 , and the clamping driving member 213 can drive the clamping block 212 to reciprocate relative to the base 211 to open or close the clamping opening.

[0080] In one embodiment, if Figure 6 and Figure 7 As shown, the clamping drive member 213 includes a telescopic cylinder 214, and the base 211 is arranged at one end of the telescopic cylinder 214 away from the mounting portion 220, and is formed with a guide hole 216 extending along the width direction X. The telescopic end of the telescopic cylinder 214 passes through the guide hole 216 and is transmission-connected to the clamping block 212.

[0081] The telescopic cylinder 214 drives the clamping block 212 to move along the width direction X toward the base 211, thereby closing the clamping opening and clamping the folded edge between the base 211 and the clamping block 212. The telescopic cylinder 214 drives the clamping block 212 to move away from the base 211 along the width direction X, thereby opening the clamping opening and loosening the clamped folded edge.

[0082] Further, in one embodiment, if Figure 6 As shown, a clamping portion 215 is provided on the side of the clamping block 212 facing the base 211. In order to better clamp the folded edge, the clamping portion 215 is any one of a rubber pad, a silicone pad, and a polyurethane cushion. When the clamping portion 215 and the base 211 clamp the top of the folded edge, it can play a buffering role, thereby reducing the risk of tearing of the folded edge clamped by the clamping head 210 during movement.

[0083] Of course, in another embodiment, the clamping portion 215 is a convex-concave toothed surface or a wavy surface, thereby reducing the contact area between the clamping head 210 and the folded edge, and reducing the contact area between the clamping portion 215 and the folded edge when the clamping portion 215 clamps the folded edge. Under the premise of not affecting the clamping force of the clamping portion 215 and the base 211 on the folded edge, the positive pressure of the clamping portion 215 on the folded edge along the width direction X of the mold body 100 is reduced, thereby reducing the risk of tearing of the folded edge during the clamping process.

[0084] like Figure 7 As shown, in one embodiment, the mounting portion 220, the lifting drive component 300, and the lifting guide component 400 are all arranged in the internal cavity of the mold body 100, and an avoidance groove 112 extending along the height direction Z is formed on the first side wall 111 corresponding to the top clamping component 200, and the clamping block 212 extends from the avoidance groove 112 to the outer surface of the first support portion 110.

[0085] Specifically, the base 211 is formed as a protrusion 217 that is adapted to the avoidance groove 112. The protrusion 217 can be slidably adapted in the avoidance groove 112 along the avoidance groove 112, and the outer surface of the protrusion 217 is flush with the outer surface of the first support portion 110. When the clamping head 210 clamps the folding edge and moves, the vertical guide rail 411 cooperates with the mounting plate 221, and the protrusion 217 on the base 211 cooperates with the avoidance groove 112 on the first side wall 111, thereby providing dual guidance for the moving direction of the clamping head 210 to ensure that the clamping head 210 can move along the height direction Z of the mold body 100.

[0086] In another embodiment, the mounting portion 220, the lifting drive component 300, and the lifting guide component 400 are all arranged on a frame outside the mold body 100. In this case, there is no need to set an avoidance groove 112 on the first support portion 110, and the components of the clamping head 210 are directly connected from the outside. This embodiment does not make any specific limitations on this.

[0087] In another alternative embodiment, the clamping drive 213 includes a telescopic cylinder 214, the telescopic base 211 of the telescopic cylinder 214 is arranged on the mounting portion 220, the middle portion of the clamping block 212 is hinged to the side of the base 211 away from the mounting portion 220, and the telescopic end of the telescopic cylinder 214 is hinged to the end of the clamping block 212 away from the folding edge.

[0088] Among them, the telescopic cylinder 214 drives the clamping block 212 to swing around the hinge point with the base 211. Specifically, the telescopic cylinder 214 drives the clamping block 212 to swing around the hinge point with the base 211 in a direction away from the base 211, and the clamping opening between the clamping block 212 and the base 211 opens, and the folded edge between the base 211 and the clamping block 212 is loosened. The telescopic cylinder 214 drives the clamping block 212 to swing around the hinge point with the base 211 in a direction close to the base 211, and the clamping opening between the clamping block 212 and the base 211 is closed, and the folded edge between the base 211 and the clamping block 212 is clamped.

[0089] The specific structure of the clamping head 210 is not limited to the structure in the above embodiment. As long as the structure of clamping the folded edge can be realized, technicians in this field can design it according to actual conditions and specific needs. This embodiment does not make any specific limitations on this.
