Technical Field

[0001] This utility model relates to the field of marking molds for garment production, specifically an adjustable marking mold for wide and narrow gussets. Background Technology

[0002] The overlay is the overlapping section in a garment's structure used for the placket area, typically located in the center of the front panel (such as in shirts, coats, and skirts). It's the area where the left and right front panels overlap at the opening, used for sewing buttons, zippers, or other closures. In garment production, the width of the overlay directly affects the garment's appearance and functionality, and adjustable overlay width marking dies are specialized tools used to precisely mark this area. These dies are used to mark the width of the overlay.

[0003] Existing techniques for marking patterns require the garment to be ironed flat and straight, then the pattern must be aligned with the garment, and the pattern is drawn while the left hand holds the pattern down and the right hand marks the pattern. However, the marking molds in existing techniques have the following drawbacks during operation: Garment production is labor-intensive, with a wide variety of products and varying widths for each product. Frequent changes in product types require frequent replacement of width and pattern templates, making the process cumbersome and costly. Utility Model Content

[0004] This utility model aims to provide an adjustable door width marking mold, mainly to solve the technical problems of the existing technology that require frequent changes of width process templates when frequently changing product varieties, which is cumbersome in operation and has high cost.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An adjustable door width marking mold has a movable groove on its base plate, which penetrates the bottom surface of the base plate and is connected to the outside. The base plate is respectively provided with an adjustment component for adjusting the marking spacing and a marking component for marking operations. The adjustment component is respectively provided with a rotation positioning component for driving the marking component to draw an arc and a sliding positioning component for driving the marking component to draw a straight line.

[0006] Preferably, the adjusting assembly includes a first hollow rod located within a movable groove. The first hollow rod is slidably and rotatably connected to the inner wall of the movable groove. A second hollow rod is fixedly connected to the top of the first hollow rod. A clearance groove is formed on the periphery of the second hollow rod. A first compression spring is installed in the clearance groove. One end of the first compression spring is fixedly connected to the inner wall of the clearance groove, and the other end of the first compression spring is fixedly connected to a connecting ring. A fixing plate is provided below the base plate. A first clearance hole is formed on the fixing plate. The first hollow rod is fixedly connected to the inner wall of the first clearance hole. The first hollow rod can slide and rotate within the movable groove. The second hollow rod fixed thereon extends upward. A first compression spring is installed in the clearance groove on the side of the second hollow rod. The spring pushes the connecting ring. The fixing plate below the connecting ring is fixed to the first hollow rod through the first clearance hole. Rotating or sliding the first hollow rod can change the position of the fixing plate relative to the base plate, i.e., adjust the width.

[0007] Preferably, a first rubber ring is fixedly connected to the bottom surface of the connecting ring, and a second rubber ring is fixedly connected to the top surface of the base plate. The first rubber ring and the second rubber ring abut against each other, and the first rubber ring and the second rubber ring are in close contact, which increases friction, assists in positioning, and reduces vibration during adjustment. It also forms a seal to prevent dust, debris, etc. from entering the interior of the adjustment component through the movable groove.

[0008] Preferably, the rotating positioning assembly includes a connecting rod located inside a second hollow rod. The connecting rod is slidably and rotatably connected to the inner wall of the second hollow rod. An internally threaded sleeve is fixedly connected to the top of the second hollow rod. A threaded post is internally threaded onto the internally threaded sleeve. The threaded post is fixedly connected to the top of the connecting rod. A handle is fixedly connected to the top of the threaded post. A positioning cone is fixedly connected to the bottom of the connecting rod. The positioning cone is located inside a first hollow rod and is slidably and rotatably connected to the inner wall of the first hollow rod. The connecting rod can slide and rotate inside the second hollow rod. Its upper end is connected to the internally threaded sleeve via the threaded post. A handle is located at the top of the threaded post. The positioning cone is fixedly attached to the bottom of the connecting rod and extends into the first hollow rod. Function: Rotating the handle allows for precise adjustment of the height of the connecting rod and the positioning cone, enabling the positioning cone to penetrate the material surface for precise positioning of the center point. The connecting rod can rotate with the mold as a whole.

[0009] Preferably, the sliding positioning component includes a T-shaped groove, which is formed on a fixed plate. A T-shaped block is slidably connected in the T-shaped groove. A hollow block is fixedly connected to the side wall of the fixed plate. A first sliding groove is formed on the side of the fixed plate near the hollow block, and the first sliding groove is connected to the hollow block. A stop block is slidably connected in the first sliding groove, and the bottom surface of the stop block abuts against the top surface of the T-shaped block. A plurality of second compression springs arranged at equal intervals are fixedly connected to the side wall of the stop block. The second compression springs are located inside the hollow block and are fixedly connected to the inner wall of the hollow block. Two second sliding grooves are formed on the bottom surface of the hollow block. A U-shaped connecting block is fixedly connected to the side wall of the stop block. The U-shaped connecting block is slidably connected to the second sliding groove and extends through the second sliding groove to the outside. The second compression springs push the stop block to press the T-shaped block, and the friction force locks the T-shaped block and the associated fixed plate in the current position. Pulling the U-shaped connecting block can overcome the spring force to move the stop block away, releasing the lock on the T-shaped block and facilitating width adjustment.

[0010] Preferably, the marking assembly includes a second clearance hole, which is formed on the base plate, penetrates the bottom surface of the base plate and communicates with the outside. A placement sleeve is fixedly connected to the base plate and communicates with the second clearance hole. A through hole is formed at the top of the placement sleeve, which penetrates the top of the placement sleeve and communicates with the inside of the placement sleeve. A marking pen is slidably connected inside the placement sleeve. The bottom end of the marking pen penetrates the second clearance hole and extends to the outside. A first arc-shaped block is fixedly connected inside the placement sleeve. A threaded groove is formed on the placement sleeve, and a threaded rod is threadedly connected to the threaded groove. A second arc-shaped block is rotatably connected to one end of the threaded rod near the marking pen. A handle is fixedly connected to the other end of the threaded rod. The placement sleeve accommodates the marking pen. Rotating the handle drives the threaded rod, pushing the second arc-shaped block closer to the first arc-shaped block, which together clamps and fixes the marking pen. Releasing the handle allows the marking pen to be replaced or adjusted. The tip of the marking pen passes through the base plate to mark lines on the material.

[0011] Preferably, a first clamping pad is fixedly connected to the first arc-shaped block, and the first clamping pad abuts against and fits tightly against the periphery of the marking pen. A second clamping pad is fixedly connected to the second arc-shaped block, and the second clamping pad abuts against and fits tightly against the periphery of the marking pen. The first and second clamping pads are made of soft material, which provides cushioning when clamping the marking pen to avoid damaging the pen body, while increasing friction to ensure that the marking pen is firmly clamped and to prevent it from loosening or shifting when drawing lines.

[0012] The beneficial effects of this utility model are: The adjustable door width marking mold provided by this utility model allows personnel to adjust the radius of the arc and the spacing of the straight lines through the adjustment component. The adjustment of the rotation positioning component allows personnel to easily rotate the device to draw arc lines with the marking component.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1-7 As shown, the adjustable door width marking mold includes a base plate 1, a movable groove 2 is provided on the base plate 1, the movable groove 2 penetrates the bottom surface of the base plate 1 and is connected to the outside, an adjustment component is provided on the base plate 1, a rotation positioning component is provided on the adjustment component, a sliding positioning component is provided on the adjustment component, and a marking component is provided on the base plate 1.

[0017] Specifically, the adjustment assembly includes a first hollow rod 3, which is located in the movable groove 2. The first hollow rod 3 is slidably and rotatably connected to the inner wall of the movable groove 2. A second hollow rod 4 is fixedly connected to the top of the first hollow rod 3. A clearance groove 7 is provided on the periphery of the second hollow rod 4. A first compression spring 8 is provided in the clearance groove 7. One end of the first compression spring 8 is fixedly connected to the inner wall of the clearance groove 7. A connecting ring 9 is fixedly connected to the other end of the first compression spring 8. A fixing plate 15 is provided below the base plate 1. A first clearance hole 16 is provided on the fixing plate 15. The first hollow rod 3 is fixedly connected to the inner wall of the first clearance hole 16.

[0018] In this embodiment, the first hollow rod 3 can slide and rotate within the movable groove 2, enabling the mold to translate and rotate within the plane of the base plate 1. The second hollow rod 4 is fixed to the top of the first hollow rod 3, forming the main body of the adjusting arm. The connecting ring 9 is elastically connected to the second hollow rod 4 via the first compression spring 8. The first rubber ring 10 is fixed to the bottom surface of the connecting ring 9, and the second rubber ring 11 is fixed to the top surface of the base plate 1. When the mold is placed on the working surface, the upward movement of the connecting ring 9 compresses the first compression spring 8, causing the first rubber ring 10 and the second rubber ring 11 to no longer be tightly fitted. This allows the mold to flexibly adjust its position to adapt to the marking requirements of different door widths and angles. The combination of the first compression spring 8, the first rubber ring 10, and the second rubber ring 11 provides downward pressure and friction. The close contact of the rubber rings generates a large static friction force. This achieves the mobility of the mold in the non-working state and its stability in the working state, preventing accidental displacement of the mold during the marking process and ensuring marking accuracy.

[0019] Specifically, a first rubber ring 10 is fixedly connected to the bottom surface of the connecting ring 9, and a second rubber ring 11 is fixedly connected to the top surface of the base plate 1, with the first rubber ring 10 and the second rubber ring 11 abutting against each other.

[0020] Specifically, the rotation positioning assembly includes a connecting rod 5, which is located inside the second hollow rod 4. The connecting rod 5 slides and rotates with the inner wall of the second hollow rod 4. An internally threaded sleeve 12 is fixedly connected to the top end of the second hollow rod 4. A threaded post 13 is internally threaded onto the internally threaded sleeve 12. The threaded post 13 is fixedly connected to the top end of the connecting rod 5. A handle 6 is fixedly connected to the top end of the threaded post 13. A positioning cone 14 is fixedly connected to the bottom end of the connecting rod 5. The positioning cone 14 is located inside the first hollow rod 3 and slides and rotates with the inner wall of the first hollow rod 3.

[0021] In this embodiment, the connecting rod 5 can slide and rotate within the second hollow rod 4 and the first hollow rod 3. The internal threaded sleeve 12 is fixed to the top of the second hollow rod 4. The threaded column 13 is threadedly engaged with the internal threaded sleeve 12. The top end is connected to the handle 6, and the bottom end is fixed to the connecting rod 5 and the positioning cone 14. Rotating the handle 6 drives the threaded column 13 to rise and fall, thereby driving the connecting rod 5 and the positioning cone 14 to rise and fall. By rotating the handle 6, the extension height of the positioning cone 14 can be precisely controlled. When it is necessary to rotate the mold to draw an arc with a certain point as the center, the positioning cone 14 is screwed down and inserted into the positioning hole. This point becomes the immovable rotation center. The thread adjustment realizes the stepless adjustment of the height of the positioning cone 14, which can adapt to different thicknesses of fabric or positioning requirements. When not in use, it can be screwed back into the rod to avoid scratching or hindering other operations. The self-locking characteristic of the thread ensures that the positioning cone 14 will not move easily due to external force after the set height, ensuring the stability of the center of the rotating line drawing.

[0022] Specifically, the sliding positioning component includes a T-shaped groove 17, which is formed on the fixed plate 15. A T-shaped block 18 is slidably connected inside the T-shaped groove 17. A hollow block 19 is fixedly connected to the side wall of the fixed plate 15. A first sliding groove 20 is formed on the side of the fixed plate 15 near the hollow block 19. The first sliding groove 20 is connected to the hollow block 19. A stop block 21 is slidably connected inside the first sliding groove 20. The bottom surface of the stop block 21 abuts against the top surface of the T-shaped block 18. A number of equally spaced second compression springs 22 are fixedly connected to the side wall of the stop block 21. The second compression springs 22 are located inside the hollow block 19 and are fixedly connected to the inner wall of the hollow block 19. Two second sliding grooves 23 are formed on the bottom surface of the hollow block 19. A U-shaped connecting block 24 is fixedly connected to the side wall of the stop block 21. The U-shaped connecting block 24 is slidably connected to the second sliding grooves 23 and extends through the second sliding grooves 23 to the outside.

[0023] In this embodiment, the T-shaped block 18 slides within the T-shaped groove 17, and the stop block 21 is pressed into the hollow block 19 by the second compression spring 22. Its bottom surface abuts against the top surface of the T-shaped block 18 under the action of the spring. The U-shaped connecting block 24 is fixed on the stop block 21 and extends to the outside through the second sliding groove 23 at the bottom of the hollow block 19. Under the action of the second compression spring 22, the stop block 21 naturally presses down to lock the T-shaped block 18, thereby fixing the sliding direction. When adjustment is needed, sliding the U-shaped connecting block 24 can move the stop block 21 and release the pressure on the T-shaped block 18. At this time, the T-shaped block 18 can slide freely within the T-shaped groove 17. When the U-shaped connecting block 24 is released, the stop block 21 automatically resets and locks. This quick locking or unlocking mechanism, which can be operated with one hand, greatly improves the adjustment efficiency. In the locked state, the friction between the stop block 21 and the T-shaped block 18 can effectively prevent the mold from sliding accidentally during the scribing process. The T-shaped groove 17 and the T-shaped block 18 cooperate to provide stable linear motion guidance, ensuring accurate sliding trajectory.

[0024] Specifically, the marking assembly includes a second clearance hole 25, which is formed on the base plate 1. The second clearance hole 25 penetrates the bottom surface of the base plate 1 and communicates with the outside. A placement sleeve 26 is fixedly connected to the base plate 1. The placement sleeve 26 is connected to the second clearance hole 25. A through hole 27 is formed at the top of the placement sleeve 26. The through hole 27 penetrates the top of the placement sleeve 26 and communicates with the inside of the placement sleeve 26. A marking pen 28 is slidably connected inside the placement sleeve 26. The bottom end of the marking pen 28 penetrates the second clearance hole 25 and extends to the outside. A first arc-shaped block 29 is fixedly connected inside the placement sleeve 26. A threaded groove 31 is formed on the placement sleeve 26. A threaded rod 32 is threadedly connected inside the threaded groove 31. A second arc-shaped block 33 is rotatably connected to one end of the threaded rod 32 near the marking pen 28. A handle 35 is fixedly connected to the other end of the threaded rod 32.

[0025] In this embodiment, the marking pen 28 is inserted into the placement sleeve 26, with its tip passing through the second clearance hole 25. The first arc-shaped block 29 is fixed to the inner wall, and the first clamping pad 30 on it is close to one side of the pen body. The threaded rod 32 is screwed in through the threaded groove 31, and its inner end is rotatably connected to the second arc-shaped block 33 with the second clamping pad 34. The outer end is connected to the handle 35. Rotating the handle 35 drives the threaded rod 32 to move forward and backward, thereby causing the second arc-shaped block 33 to move closer to or away from the first arc-shaped block 29. The marking pen 28 can be easily removed or replaced by releasing the threaded rod. The operation is convenient. By changing the insertion depth of the marking pen 28 in the placement sleeve 26, the pen tip extension length can be finely adjusted to adapt to different marking depth requirements or to replace the marking pen 28 with a different length.

[0026] Specifically, a first clamping pad 30 is fixedly connected to the first arc-shaped block 29, and the first clamping pad 30 abuts against and fits tightly against the periphery of the scribing pen 28. A second clamping pad 34 is fixedly connected to the second arc-shaped block 33, and the second clamping pad 34 abuts against and fits tightly against the periphery of the scribing pen 28.

[0027] In this embodiment, rotating the handle 35 allows the second clamping pad 34 and the first clamping pad 30 to work together to firmly clamp the pens 28 of different diameters from both sides, preventing the pens from loosening or rotating when drawing lines, ensuring stable and accurate drawing, and protecting the pen body from being damaged by metal parts.

[0028] As can be seen from the above, the specific embodiments of this utility model are as follows: Insert the marking pen 28 into the through hole 27 at the top of the sleeve 26. The pen tip passes through the second clearance hole 25 and extends out of the bottom surface of the base plate 1. Rotate the handle 35 to drive the threaded rod 32 to screw into the threaded groove 31, pushing the second arc-shaped block 33 closer to the first arc-shaped block 29. The first clamping pad 30 and the second clamping pad 34 together clamp the pen body of the marking pen 28, achieving a stable installation and adapting to different pen diameters. Rotate the handle 35 in the opposite direction to loosen and replace the marking pen. Place the mold on the surface of the workpiece to be marked and press down the base plate 1 to make it flat. Rotating handle 6 drives the threaded column 13 to screw in or out of the internal threaded sleeve 12, causing the connecting rod 5 and the positioning cone 14 to move downwards until the tip of the positioning cone 14 pierces the preset center point on the workpiece surface, achieving precise positioning of the center. Moving the connecting ring 9 upwards overcomes the elastic force of the first compression spring 8 and moves slightly upwards, causing the first rubber ring 10 to separate from the second rubber ring 11. At the same time, the first hollow rod 3 slides or rotates laterally and moves within the movable groove 2. The first hollow rod 3 drives the fixed plate 15 to move synchronously, changing its position relative to the base plate. The distance of the second clearance hole 25 on the upper part is adjusted to control the marking radius. Loosening the connecting ring 9, the first compression spring 8 pushes the connecting ring 9 downwards, causing the first rubber ring 10 and the second rubber ring 11 to re-fit tightly, providing initial frictional positioning. The positioning cone 14 is inserted into the center point. With the positioning cone 14 as the axis, the mold rotates as a whole. The tip of the marking pen 28 marks a clear arc mark of the set radius on the workpiece surface. Under the continuous pushing force of the second compression spring 22, the bottom surface of the stop block 21 presses tightly against the top of the T-shaped block 18. The T-block 18 is firmly locked by friction. When the width needs to be adjusted again, the stop block 21 is pulled outward by the U-shaped connecting block 24 and slid in the first sliding groove 20, compressing the second compression spring 22, so that the bottom surface of the stop block 21 is separated from the top surface of the T-block 18, and the locking of the T-block 18 is released. At this time, the fixed plate 15 can be slid freely to adjust the width. The handle 6 is lifted to make the positioning cone 14 separate from the workpiece surface. At this time, the operator slides the mold, and the tip of the marking pen 28 draws a clear marking line with a set spacing on the workpiece surface.

[0029] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
