DETAILED DESCRIPTION

[0014] The principles and characteristics of the application will be described below in combination with the drawings, and the examples are only used to explain the application and not to limit the scope of the application.

[0015] As shown in Figs. 1-3 A door fly zipper composite mold, comprising a bottom plate 1 for carrying the sewing workpiece, an intermediate clamping plate 2 for positioning the zipper and pre-positioning the door plate and the lining, and a cover plate 3 for pressing and fixing the workpiece and controlling the panel consumption; one side of the intermediate clamping plate 2 is flexibly connected with the bottom plate 1, and one side of the cover plate 3 is flexibly connected with the bottom plate 1, so that the intermediate clamping plate 2 and the cover plate 3 can be opened and closed relative to the bottom plate 1; the bottom plate 1, the intermediate clamping plate 2 and the cover plate 3 are flexibly connected on one side to form a flip-open structure, without disassembly or transfer of the workpiece, all processes are completed on the same mold, avoiding positioning deviation in the transfer process of the workpiece, the flexible connection design ensures that the intermediate clamping plate 2 and the cover plate 3 can be flexibly flipped, the operation is convenient, the manual operation strength is reduced, and ordinary personnel can operate without complex training. The flexible connection uses a flexible connecting piece 31, and the flexible connecting piece 31 uses transparent tape or adhesive tape.

[0016] The bottom plate 1, the intermediate clamping plate 2 and the cover plate 3 are all provided with groove structures arranged along the sewing path of the workpiece, and the groove structures of the three are coincided with each other to adapt to the positioning and sewing of the front panel, the zipper, the door plate and the lining, avoid the subjective error of manual alignment, solve the quality problems of zipper skew, door plate misplacement and panel deviation in traditional processing, and ensure the consistency of different batches of products.

[0017] The bottom plate 1 and the cover plate 3 are provided with anti-displacement components 211 for preventing the workpiece from shifting and consumption control components for forming process slack of the front panel, the anti-displacement components 211 prevent the cutting piece from shifting due to machine vibration or pulling during the sewing process by increasing the friction, further improving the alignment accuracy; the consumption control components (such as sponge strips that bite each other) can make the front panel form uniform process slack, meet the requirements of flexibility and fit of the garment door fly, avoid wrinkles caused by too tight or deformation caused by too loose, and ensure the appearance of the finished product.

[0018] The intermediate clamping plate 2 is provided with a forming area 26 adapted to the shape of the door plate and the lining, and the intermediate clamping plate 2 cooperates with the cover plate 3 to form a step-by-step sewing structure, realizing the first sewing of the front panel and the zipper, and the second sewing of the front panel and the door plate / lining. The forming area 26 is a groove structure opened on the intermediate clamping plate 2, and the shape of the groove structure is consistent with the shape of the finished door plate and the finished lining. The forming area 26 of the intermediate clamping plate 2 is adapted to the shape of the door plate and the lining, which can be directly put into the workpiece to complete the pre-positioning, saving the cumbersome process of drawing width marks and manual alignment in traditional processing, and shortening the processing time; the step-by-step sewing structure of first sewing the zipper-panel and then sewing the door plate / lining-panel divides the complex door fly processing into two simple operations, which can be completed without high-skilled workers, reducing the labor cost and technical threshold of enterprises.

[0019] In the application, the groove structure on the bottom plate 1 includes a long strip-shaped track matched with the shape of the front panel piece and first and second through grooves 21 and 22 opened on both sides of the long strip-shaped track. The track shape is matched with the front panel piece to provide a dedicated placement area for the piece, directly limit the placement profile of the piece, avoid problems such as distortion and deviation of the piece, ensure the uniformity of the initial position of the piece, and there is no need for manual measurement or marking to determine the placement range of the piece. The operator can directly insert the piece into the track, simplifying the positioning steps and reducing the operation threshold. The first through groove 21 is used for positioning the left front panel piece and is matched with the sewing path of the zipper and the door plate. The second through groove 22 is used for positioning the right front panel piece and is matched with the sewing path of the zipper and the inner panel. The two side through grooves correspond to the left and right front panel pieces respectively, realizing separate positioning of the left and right pieces, avoiding mutual interference of the pieces, ensuring independent and accurate positions of the pieces, and solving the problems of misalignment and overlap of the pieces in traditional processing. The first through groove 21 is matched with the sewing path of the zipper and the door plate, and the second through groove 22 is matched with the sewing path of the zipper and the inner panel. The sewing trajectories of different components are planned in advance, so that the needle trace can accurately run along the through groove during subsequent sewing, ensuring the sewing alignment accuracy of the zipper, the door plate, the inner panel and the corresponding piece. The lengths of the first and second through grooves 21 and 22 are consistent with the length of the front panel piece, which limits the placement range of the piece from the size, avoids incomplete sewing caused by excessive exposure or excessive shortness of the piece, ensures the uniformity of the door panel length of all processed workpieces, improves the batch consistency of products, and provides a reference for subsequent consumption control components. The design of consistent length ensures that the overall length of the piece still meets the product specification requirements when forming process slack, avoiding excessive or insufficient slack affecting the pattern.

[0020] In the application, the anti-displacement component 211 is sandpaper pasted on both sides of the first and second through grooves 21 and 22. The sandpaper surface has high friction, and after being pasted on both sides of the first and second through grooves 21 and 22, it can clamp the left and right front panel pieces placed in the through grooves through friction, avoiding displacement of the pieces along the length direction or transversely during sewing due to machine vibration or thread pulling, ensuring the alignment accuracy of the pieces with the zipper, the door plate / inner panel, without the need for additional setting of buckles, pressure strips and other complex fixing structures. Passive fixation can be achieved only through the friction of the sandpaper, without affecting the quick placement and removal of the pieces, balancing the fixing effect and operation convenience, and forming double positioning of contour limitation and friction fixation with the groove structure of the bottom plate 1, further reducing the dependence on the placement accuracy of the operator.
