Description

Technical Field

[0001] This utility model belongs to the field of clothing processing technology, specifically relating to a collar sewing guide mold. Background Technology

[0002] In garment manufacturing, the sewing of the collar is a crucial step and also one of the more challenging areas. Typically, sewing dies are used to assist in this process. A custom-made sewing die is created to match the collar's specifications, and the guide grooves on the die serve as the sewing path, ensuring consistency in the collar's stitching.

[0003] Due to the diverse sizes and angles of collars, custom sewing molds are required for each type of collar. This not only incurs significant mold manufacturing costs but also results in many molds remaining idle for extended periods because many collar specifications are not commonly used, thus affecting the effective utilization rate of collar molds. Utility Model Content

[0004] This utility model provides a collar sewing guide mold, which aims to reduce the manufacturing cost of collar sewing molds and improve the effective utilization rate of collar sewing molds.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a collar sewing guide mold, comprising:

[0006] The clamping bar has an open state and a fastened state. When fastened, it forms a clamping opening, and the clamping opening has several clamping positions that are spaced apart along the length of the clamping bar.

[0007] Two pairs of clamping plates for holding the collar corners are spaced apart and mirror-distributed along the length of the clamping strip. The same edge of each pair of clamping plates is clamped and fixed to one of the clamping positions, and each pair of clamping plates has a central hole.

[0008] Two pairs of mold plates are respectively set in the central holes of two pairs of clamping plates. Multiple collar corner sewing guide grooves are distributed around the circumference of the mold plates. Each collar corner sewing guide groove is used to match collar corners of different shapes.

[0009] Two pairs of connecting plates are detachably connected between two pairs of clamping plates, forming a collar edge sewing guide groove between the two pairs of connecting plates. The two ends of the collar edge sewing guide groove are respectively connected to one of the collar corner sewing guide grooves.

[0010] In one possible implementation, each pair of clamps includes a base plate and a cover plate; each pair of mold plates includes a tray and a pressure plate, with corresponding collar corner sewing guide grooves on the tray and pressure plate; wherein the tray is connected to the central hole of the base plate, and the pressure plate is connected to the central hole of the pressure plate.

[0011] In some embodiments, the base plate and the cover plate are provided with a ring of positioning holes spaced apart around their respective central holes, and the edges of the tray and the pressure plate are provided with a ring of positioning pins; wherein, each positioning pin is inserted into each positioning hole in a one-to-one correspondence.

[0012] For example, the upper surface of the base plate and the lower surface of the cover plate respectively form a groove around their respective central holes; the periphery of the tray and the pressure plate are provided with overlapping platforms suitable for embedding into the grooves; wherein, the positioning insertion hole is located at the bottom of the groove, and the positioning pin is located at the overlapping platform.

[0013] For example, the edges of the base plate and the cover plate are provided with connecting channels that communicate with their respective central holes; each pair of connecting plates includes an upper connecting plate and a lower connecting plate, which are used to clamp the collar edge located between the two collar corners; wherein, the upper connecting plate extends into the connecting channel of the base plate and connects with the base plate, and the lower connecting plate extends into the connecting channel of the cover plate and connects with the cover plate.

[0014] In one possible implementation, an outer connecting plate and an inner connecting plate are formed on both sides of the connecting channel; the upper and lower connecting plates of one pair of connecting plates are respectively overlapped and fixed to the outer connecting plate, and the upper and lower connecting plates of another pair of connecting plates are respectively overlapped and fixed to the inner connecting plate.

[0015] In some embodiments, both the outer and inner connecting pieces are provided with multiple connecting pins, and both the upper and lower connecting plates are provided with multiple connecting holes; wherein, each connecting pin is inserted into each connecting hole in a one-to-one correspondence.

[0016] For example, the cover plate has a folded groove near the clamping opening, and the cover plate folds up and down based on the folded groove.

[0017] For example, the inner bottom wall of the clamp has several ribs evenly distributed. When the clamp is engaged, each rib abuts against the inner top wall of the clamp. Each clamping position includes at least two ribs. The edge of the clamp plate is provided with at least two through holes, each through hole corresponding to each rib of the clamping position.

[0018] In some embodiments, the clamping strip includes a lower corner strip and an upper corner strip, which are hinged together by a pivot; wherein, the lower corner strip has pins at both ends and the upper corner strip has pin holes at both ends; in the fastened state, each pin is inserted into each corresponding pin hole.

[0019] The beneficial effects of the collar sewing guide mold provided by this utility model are as follows: Compared with the prior art, the collar sewing guide mold of this utility model clamps two pairs of clamping plates in the clamping opening formed by the clamping strips in the snap-fit ​​state, and connects the two pairs of clamping plates into one body by two pairs of connecting plates, thereby connecting the collar corner sewing guide groove on the mold plate connected in the center hole of the clamping plates and the collar edge sewing guide groove formed between the two pairs of connecting plates, thus forming a complete collar sewing guide groove.

[0020] When sewing the same collar angle design for different collar lengths, the clamping position of one pair of clamps can be adjusted after opening the clamping strip and removing the connecting plate. This adjusts the spacing between the two pairs of clamps. After adjustment, the clamping strip is fastened again, and a connecting plate matching the current spacing is selected to reconnect the two pairs of clamps, thus forming a collar sewing guide groove that matches the current collar length. In this case, only the connecting plate needs to be customized for the collar length type, without the need to replace the clamps and mold plate. Therefore, manufacturing costs can be reduced, and the effective utilization rate of clamps and mold plates can be improved.

[0021] When sewing different collar corner shapes, simply rotate the two pairs of mold plates in the central hole to align and connect the collar corner sewing guide groove that matches the collar corner shape to be sewn with the collar edge sewing guide groove. This can simultaneously meet the sewing needs of multiple collar corner shapes, which not only reduces the types of mold customization and thus lowers mold costs, but also further improves the effective utilization rate of the mold.

It should be understood that the terms "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" or "several" means two or more, unless otherwise explicitly specified.

[0031] Please refer to the following: Figures 1 to 6The collar sewing guide mold provided by this utility model will now be described. The collar sewing guide mold includes clamping strips 10, two pairs of clamping plates 20 for holding the collar corners, two pairs of mold plates 30 and two pairs of connecting plates 40. The clamping strip 10 has an open state and a fastened state. In the fastened state, it forms a clamping opening 100. The clamping opening 100 has several clamping positions spaced apart along the length of the clamping strip 10. Two pairs of clamping plates 20 are spaced apart and mirror-distributed along the length of the clamping strip 10. The same edge of each pair of clamping plates 20 is clamped and fixed to one of the clamping positions, and each pair of clamping plates 20 has a central hole 200. Two pairs of mold plates 30 are respectively disposed in the central holes 200 of the two pairs of clamping plates 20. The mold plates 30 have multiple collar corner sewing guide grooves 300 spaced apart along their circumference. Each collar corner sewing guide groove 300 is used to match collar corners of different shapes. Two pairs of connecting plates 40 are detachably connected between the two pairs of clamping plates 20. The two pairs of connecting plates 40 form a collar edge sewing guide groove 400. The two ends of the collar edge sewing guide groove 400 are respectively connected to one of the collar corner sewing guide grooves 300.

[0032] It should be noted that the overall structure of a collar includes two collar corners and the collar edge between the two collar corners; the differences between different collar corner shapes are mainly in the difference between right angles and rounded corners, the difference in the angle of the right angle, and the difference in the radius of the arc; the difference in collar size is mainly reflected in the difference in the length of the collar edge, for example, the collar of a large-sized garment is relatively longer than that of a small-sized garment.

[0033] It should be noted that, considering the clamping effect on the collar corners and collar edges, in this embodiment, each pair of clamping plates 20, each pair of mold plates 30, and each pair of connecting plates 40 are composed of two corresponding upper and lower parts. The mold plate 30 can rotate at a corresponding angle within the central hole 200 to accommodate the positions of its respective collar corner sewing guide grooves 300, thereby enabling the same mold plate 30 to meet the matching requirements of various styles.

[0034] The connecting plate 40 can be configured as a freely retractable structure or can be replaced as a set. Considering that the collar edge seam may be straight or curved, simply adjusting the length by stretching can only be applied to the form where the collar edge seam is straight. Therefore, in this embodiment, it is preferable to use a configuration of multiple connecting plates 40 for selection. When the collar edge length changes, the clamping position of the two pairs of clamping plates 20 can be adjusted and the corresponding connecting plate 40 can be selected. Compared with the prior art, which requires customizing molds for each size, here only the connecting plate 40 needs to be made without customizing the whole mold. This not only saves materials but also reduces processing costs, thereby reducing mold manufacturing costs.

[0035] Compared with the prior art, the collar sewing guide mold provided in this embodiment clamps two pairs of clamping plates 20 in the clamping opening 100 formed by the clamping strip 10 in the snap-fit ​​state, and connects the two pairs of clamping plates 20 into one body by two pairs of connecting plates 40, so that the collar corner sewing guide groove 300 on the mold plate 30 connected in the center hole 200 of the clamping plate 20 and the collar edge sewing guide groove 400 formed between the two pairs of connecting plates 40 are connected, thereby forming a complete collar sewing guide groove.

[0036] When sewing different collar lengths under the same collar corner design, the clamping position of one pair of clamping plates 20 can be adjusted after opening the clamping strip 10 and removing the connecting plate 40, thereby adjusting the distance between the two pairs of clamping plates 20. After adjustment, the clamping strip 10 is fastened again, and the connecting plate 40 matching the current distance is selected to reconnect the two pairs of clamping plates 20, thereby forming a collar sewing guide groove that matches the current collar length. In this case, only the connecting plate 40 needs to be customized for the collar length type, without replacing the clamping plates 20 and the mold plate 30. Therefore, the manufacturing cost can be reduced and the effective utilization rate of the clamping plates 20 and the mold plate 30 can be improved.

[0037] When performing sewing operations for different collar corner shapes, simply rotate the two pairs of mold plates 30 in the central hole 200 so that the collar corner sewing guide groove 300 matching the collar corner shape to be sewn is aligned and connected with the collar edge sewing guide groove 400. This can simultaneously meet the sewing operations for multiple collar corner shapes, which not only reduces the types of mold customization and thus reduces mold costs, but also further improves the effective utilization rate of the mold.

[0038] In some embodiments, see Figures 2 to 4 Each pair of clamping plates 20 includes a base plate 21 and a cover plate 22; each pair of mold plates 30 includes a tray 31 and a pressure plate 32, and each collar corner sewing guide groove 300 is provided on the tray 31 and the pressure plate 32 respectively; wherein, the tray 31 is connected to the center hole 200 of the base plate 21, and the pressure plate 32 is connected to the center hole 200 of the pressure plate 32.

[0039] When sewing the collar, flip open the cover plate 22, place the collar on the base plate 21 and align the collar corners with the corresponding collar corner sewing guide grooves 300 on the tray 31. Then, press the cover plate 22 against the collar to clamp and fix it. The operation is simple and convenient. For different collar corner shapes, simply rotate the tray 31 within the center hole 200 on the base plate 21 and the pressure plate 32 within the center hole 200 on the cover plate 22 by the same angle so that the collar corner sewing guide groove 300 matching the collar corner shape is aligned with the collar edge sewing guide groove 400. Adjustment is convenient.

[0040] As an optional connection method for the aforementioned mold plate 30 and clamping plate 20, please refer to Figure 3 and Figure 4Both the base plate 21 and the cover plate 22 are provided with a ring of positioning holes 211 spaced around their respective center holes 200, and the edges of the tray 31 and the pressure plate 32 are provided with a ring of positioning pins 321; wherein, each positioning pin 321 is inserted into each positioning hole 211 in a one-to-one correspondence.

[0041] By inserting the positioning pin 321 into the positioning hole 211, a reliable connection between the tray 31 and the pressure plate 32 can be achieved, thus avoiding the situation where the tray 31 and the pressure plate 32 rotate and misalign, which would affect the accuracy of the sewing position. When it is necessary to change the collar corner sewing guide groove 300, simply pull the positioning pin 321 out of the positioning hole 211, and then rotate the tray 31 and the pressure plate 32 into place and re-insert them. The operation is simple and convenient.

[0042] It should be noted that, in order to improve the convenience of selecting and adjusting the collar corner sewing guide groove 300 and the alignment accuracy between the collar corner sewing guide groove 300 and the collar edge sewing guide groove 400 after adjustment, the number of positioning holes 211 provided on the base plate 21 and cover plate 22 is the same as the number of collar corner sewing guide grooves 300 provided on the tray 31 and pressure plate 32. This ensures that after the tray 31 and pressure plate 32 are rotated into place and the positioning pin 321 is re-inserted into the positioning hole 211, the collar corner sewing guide groove 300 can be aligned with the collar edge sewing guide groove 400.

[0043] To ensure the clamping stability of the clamping plates 20 against the collar corners, please refer to [link / reference needed]. Figure 3 and Figure 4 In this embodiment, the upper surface of the base plate 21 and the lower surface of the cover plate 22 respectively form a groove 212 around their respective central holes 200; the periphery of the tray 31 and the pressure plate 32 are provided with overlapping platforms 322 suitable for embedding into the groove 212; wherein, the positioning insertion hole 211 is provided at the bottom of the groove 212, and the positioning pin 321 is provided at the overlapping platform 322.

[0044] By setting the groove 212, the tray 31 and the pressure plate 32 can be embedded, thereby forming a flat surface on the upper surface of the base plate 21 and the lower surface of the cover plate 22, which increases the clamping area of ​​the collar corner and thus improves the clamping stability. In addition, the groove 212 on the upper surface of the base plate 21 can support the overlapping platform 322 of the edge of the tray 31, and the groove 212 on the lower surface of the cover plate 22 can support the overlapping platform 322 of the edge of the pressure plate 32. This can prevent the tray 31 and the pressure plate 32 from being dislodged from the groove 212 during the clamping of the collar corner, further improving the clamping stability of the collar corner.

[0045] It should be noted that, please refer to... Figures 3 to 5Understandably, in this embodiment, the edges of the base plate 21 and the cover plate 22 are provided with connecting channels 213 that communicate with their respective central holes 200; each pair of connecting plates 40 includes an upper connecting plate 41 and a lower connecting plate 42, which are used to cooperate in clamping the collar edge located between the two collar corners; wherein, the upper connecting plate 41 extends into the connecting channel 213 of the base plate 21 and connects to the base plate 21, and the lower connecting plate 42 extends into the connecting channel 213 of the cover plate 22 and connects to the cover plate 22.

[0046] By setting a connecting channel 213 into which the end of the connecting plate 40 can be inserted, the collar edge sewing guide groove 400 and the collar corner sewing guide groove 300 can be aligned and connected. The upper connecting plate 41 can connect the two cover plates 22 into one piece. When the cover plate 22 is opened, the upper connecting plate 41 is opened along with the cover plate 22. Then the collar can be placed on the two base plates 21 and the lower connecting plate 42, so that the two collar corners are aligned with the two collar corner sewing guide grooves 300 respectively, and the collar edge is aligned with the collar edge sewing guide groove 400. Then the two cover plates 22 and the upper connecting plate 41 are pressed on the collar. The operation is simple and convenient.

[0047] For some possible implementations, please refer to [link / reference]. Figure 4 and Figure 5 The two sides of the connecting channel 213 are respectively formed with an outer connecting plate 2131 and an inner connecting plate 2132; the upper connecting plate 41 and the lower connecting plate 42 of one pair of connecting plates 40 are respectively overlapped and fixed to the outer connecting plate 2131, and the upper connecting plate 41 and the lower connecting plate 42 of the other pair of connecting plates 40 are respectively overlapped and fixed to the inner connecting plate 2132.

[0048] Since the collar edge sewing guide groove 400 is formed by the gap between two pairs of connecting plates 40, one pair of connecting plates 40 is connected to the outer connecting piece 2131 of the connecting channel 213, and the other pair of connecting plates 40 is connected to the inner connecting piece 2132. This allows the collar edge sewing guide groove 400 to be located in the middle of the connecting channel 213, thereby realizing the connection between the collar edge sewing guide groove 400 and the collar corner sewing guide groove 300. The structure is simple and the connection is reliable.

[0049] Specifically, the outer connecting piece 2131 and the inner connecting piece 2132 are provided with multiple connecting pins 2133, and the upper connecting plate 41 and the lower connecting plate 42 are provided with multiple connecting holes 43; wherein, each connecting pin 2133 is inserted into each connecting hole 43 in a one-to-one correspondence.

[0050] The upper connecting plate 41 and the lower connecting plate 42 are detachably connected on the corresponding outer connecting piece 2131 and inner connecting piece 2132 by interlocking the connecting hole 43 and the connecting pin 2133. This not only ensures the connection position accuracy between the upper connecting plate 41 and the two cover plates 22, and the connection position accuracy between the lower connecting plate 42 and the two base plates 21, thus ensuring the alignment accuracy of the upper and lower collar edge sewing guide grooves 400, but also facilitates disassembly and assembly operations.

[0051] In some embodiments, such as Figure 2 As shown, the cover plate 22 has a folded groove 221 near the clamp 100, and the cover plate 22 folds up and down based on the folded groove 221. The base plate 21 can be made of a rigid sheet material such as acrylic sheet, while the cover plate 22 is made of a flexible sheet material such as PVC sheet. The folded groove 221 on the cover plate 22 allows it to bend along the folded groove 221 when the cover plate 22 is opened, thereby ensuring that the cover plate 22 can be opened as a whole for easy placement of the collar and improving the ease of operation.

[0052] For some possible implementations, please refer to [link / reference]. Figure 4 and Figure 6 The inner bottom wall of the clamp 100 is provided with a number of ribs 13 at equal intervals. When the clamp is engaged, each rib 13 abuts against the inner top wall of the clamp 100. Each clamping position includes at least two ribs 13. The edge of the clamping plate 20 is provided with at least two through holes 23. Each through hole 23 is respectively fitted onto each rib 13 of the clamping position.

[0053] When the clip 10 is in the open position, the end of the rib 13 is exposed. At this time, the clip 20 can be easily removed from the original clamping position. Then, the perforation 23 on the clip 20 is fitted onto the rib 13 at the target clamping position. The clip 10 is then fastened again to complete the position adjustment of the clip 20. The operation is simple and can ensure the positional accuracy of the clip 20, thereby ensuring the quality of the collar sewing.

[0054] For example, such as Figure 6 As shown, the clamping bar 10 includes a lower corner bar 11 and an upper corner bar 12, which are hinged together by a pivot. The lower corner bar 11 has pins 111 at both ends, and the upper corner bar 12 has pin holes 121 at both ends. In the fastened state, each pin 111 is inserted into each pin hole 121.

[0055] The upper corner strip 12 and the lower corner strip 11 are hinged together to form a flip-up clamping strip 10. At the same time, the cooperation between the pin 111 and the pin hole 121 not only ensures the stability of the fastening state, but also makes it convenient to flip up the clamping strip 10 to adjust the position of the clamping plate 20.

[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
