[0047] Example 1:

[0048] A clothes rack drawstring length adjustment device is used to adjust the length of the drawstring 3 between the cord buckle 1 and the drawstring hook 2. Figure 1 As shown, the clothes rack drawstring length adjustment device specifically includes a movable mold 4, a fixing unit 5 provided on the movable mold 4 and a drawstring adjustment unit 6 for adjusting the length of the drawstring 3.

[0049] The fixing unit 5 of this embodiment includes a cord lock fixing assembly 51 for fixing the cord lock 1 and a cord hook fixing assembly 52 for fixing the cord hook 2. At least two cord wrapping supports 53 are provided between the cord lock fixing assembly 51 and the cord hook fixing assembly 52. ​​The movable mold 4 is also provided with a cord fixing assembly 54 for fixing the cord 3 extending from the end of the cord lock 1, and a cord positioning assembly 55 for fixing the spool (i.e., the next cord lock 1) extending from the end of the cord hook 2.

[0050] The rope adjustment unit 6 of this embodiment is used to pull the rope 3 around the rope support 53 to adjust its length. It includes a cylinder 61 and a movable slider 62 provided at the top of the piston rod of the cylinder 61. The movable slider 62 is provided with a rope positioning column 63.

[0051] Using the first molded product as a test piece, the draw cord 3 at the cord buckle 1 and cord hook 2 of the coat rack draw cord product is clamped and secured by the cord buckle fixing assembly 51 and cord hook fixing assembly 52, respectively. The draw cord 3 between the two is then hung on the cord positioning post 63 of the movable slider 62 via the cord winding support 53. Activating the cylinder 61 tensions the draw cord 3 outward to adjust its length. The length of the draw cord 3 between the cord buckle 1 and the cord hook 2 is then tested. If the length meets the preset requirements, the sliding distance of the movable slider 62 is used as the standard for subsequent large-scale production. If the length does not meet the requirements, the sliding distance of the piston rod of the cylinder 61 is continuously adjusted until it meets the preset requirements. Through these multiple length adjustment pre-tests, the relationship between the sliding distance of the movable slider 62 and the final draw cord 3 length is confirmed, allowing precise control of the draw cord 3 length between the cord buckle 1 and the cord hook 2 in subsequent production.

[0052] During production, referring to the above procedures, the draw cord 3 is adjusted in length and then hooked onto the cord positioning column 63. The cord clip 1 and cord hook 2 are clamped and secured by the cord clip fixing assembly 51 and cord hook fixing assembly 52, respectively. The cord 3 extending from the end of the cord clip 1 is secured by the cord fixing assembly 54, and the spool (i.e., the next cord clip 1) is secured by the spool positioning assembly 55. Once secured, subsequent mold closing and injection molding are performed to produce a coat rack draw cord product with a uniform length of the middle cord 3 within the tolerance range.

[0053] Example 2:

[0054] A coat rack drawstring length adjustment device is used to adjust the length of a drawstring 3 between a cord buckle 1 and a drawstring hook 2. The coat rack drawstring length adjustment device specifically includes a movable mold 4, a fixing unit 5 provided on the movable mold 4, and a drawstring adjustment unit 6 for adjusting the length of the drawstring 3.

[0055] like Figure 2-6As shown, the fixing unit 5 of this embodiment includes a rope lock fixing assembly 51 for fixing the rope lock 1 and a rope hook fixing assembly 52 for fixing the rope hook 2. The rope lock fixing assembly 51 includes two clamping blocks, with the rope lock 1 positioned between the two clamping blocks, and the ropes extending from both ends of the rope lock 1 are clamped in the corresponding clamping blocks; the rope hook fixing assembly 52 includes two clamping blocks, with the rope hook 2 positioned between the two clamping blocks, and the ropes extending from both ends of the rope hook 2 are clamped in the corresponding clamping blocks. The rope lock fixing assembly 51, the rope hook fixing assembly 52, the ropes extending from both ends of the rope lock 1, and the ropes extending from both ends of the rope hook 2 are located on the same axis. At least two rope winding supports 53 are provided between the rope lock fixing assembly 51 and the rope hook fixing assembly 52 of this embodiment. The rope winding supports 53 can be conventional hexagon socket head screws.

[0056] The movable mold 4 of this embodiment is also provided with a drawstring fixing assembly 54 for fixing the drawstring 3 at the protruding end of the rope buckle 1. The drawstring fixing assembly 54 includes a vertically arranged support member 541 and a pressure plate 542 slidably arranged on the support member 541. An annular limiter 543 is provided on the top of the support member 541, and a spring 544 is connected between the top surface of the pressure plate 542 and the annular limiter 543. The support member 541 of this embodiment can be a conventional hexagon socket screw, which can be threadedly connected and fixed to the movable mold 1. The slug positioning assembly 55 includes a plurality of positioning columns that can be positioned and matched with the slug, and the slug (i.e., the rope buckle 1 of the next product to be injected) can be accurately clamped on the positioning column.

[0057] The cord adjustment unit 6 of this embodiment is used to pull the cord 3 around the cord winding support 53 for length adjustment. It comprises a cylinder 61 and a movable slider 62 mounted at the top of the piston rod of cylinder 61. The piston rod of cylinder 61 extends and retracts perpendicularly to the axis between the cord lock assembly 51 and the cord hook assembly 52. ​​A slot 41 is defined on the movable mold 4 for the movable slider 62 to slide. A cord positioning post 63 is mounted on the movable slider 62. The cord 3 is wound around the cord positioning post 63 and, driven by cylinder 61, is tightened until the desired length is achieved. A positioning member 611 is sleeved on the piston rod of cylinder 61, and a stopper 42 is provided on the movable mold 4 to engage with the positioning member 611. After the sliding distance of the movable slider 62 is determined in a preliminary length adjustment test, the positioning member 611 is moved or rotated to engage the stopper 42 for positional adjustment. This ensures that the cord 3 can be uniformly adjusted to its length while hanging on the cord positioning post 63 during subsequent injection molding.

[0058] Example 3:

[0059] This embodiment provides a mold including the coat rack drawstring length adjustment device described in embodiment 2. Figure 7-8As shown, the mold of this embodiment specifically includes a mold base, a movable mold 4, and a fixed mold 7 mounted on the mold base. A mold cavity for injection molding is formed between the movable mold 4 and the fixed mold 7. A cylinder fixing block 8 is provided on the side wall of the movable mold, and a cylinder 61 is mounted on the cylinder fixing block 8. A manual valve 9 for controlling the start and stop of the cylinder 61 is also provided on the side wall of the movable mold. The manual valve is connected to the controller signal of the cylinder 61, and the start and stop of the cylinder 61 can be controlled by adjusting the manual valve 9.

[0060] This embodiment integrates the entire coat rack drawstring length adjustment device into a common injection mold, and cleverly combines injection molding and length adjustment. The method of using the mold of this embodiment is as follows:

[0061] The product molded from the first mold was used as a test product. At this point, the length of the drawstring 3 between the rope buckle 1 and the rope hook 2 was not precisely controlled. Based on product requirements, the preset length of the drawstring 3 was confirmed to be 155±2mm. The drawstring 3 extending from the end of the rope buckle 1 was pressed against the pressure plate 542 of the rope fixing assembly 54. The rope buckle fixing assembly 51 and the rope hook fixing assembly 52 were used to respectively clip and fix the drawstring 3 at the rope buckle 1 and the rope hook 2. At this point, only the drawstring 3 passing through the rope hook 2 could be adjusted in length. The drawstring 3 between the rope buckle 1 and the rope hook 2 was then hung on the rope positioning column 63 of the movable slider 62. The cylinder 61 was then opened via the manual valve 9. The movable slider 62 on the piston rod of the cylinder 61 began to pull the drawstring 3 outward, and the sliding distance of the movable slider 62 was recorded. The length of the draw cord 3 between the cord lock 1 and the draw cord hook 2 is then checked. When the length meets the preset requirements, the sliding distance of the movable slider 62 is determined, and the positioning member 611 is moved or rotated to engage the limit platform 42 for positioning. This prevents piston rod movement from causing a change in the sliding distance of the movable slider 62, thereby ensuring that the final product will have a uniform length as long as the draw cord 3 is hung on the draw cord positioning column 63 during the subsequent injection molding process. If the measured length does not meet the preset length requirements, the sliding distance of the movable slider 62 is continuously adjusted until the draw cord 3 length meets the preset length requirements, thereby determining the final sliding distance.

[0062] During production, referring to the above procedures, the draw cord 3 is adjusted in length and then hooked onto the cord positioning column 63. The cord clip 1 and cord hook 2 are clamped and secured by the cord clip fixing assembly 51 and cord hook fixing assembly 52, respectively. The cord 3 extending from the end of the cord clip 1 is secured by the cord fixing assembly 54, and the spool (i.e., the next cord clip 1) is secured by the spool positioning assembly 55. Once secured, subsequent mold closing and injection molding are performed to produce a coat rack draw cord product with a uniform length of the middle cord 3 within the tolerance range.

[0063] If the preset length of the middle section of the drawstring 3 of the new product is 200±2mm, refer to the above steps to re-adjust the length pre-test, confirm the sliding distance of the new movable slider 62, and carry out subsequent mold closing and injection molding production to produce a new batch of coat rack drawstring products with uniform length.

[0064] The above description of the embodiments is intended to facilitate understanding and use of the utility model by those skilled in the art. Those skilled in the art will readily be able to make various modifications to these embodiments and apply the general principles described herein to other embodiments without requiring inventive effort. Therefore, the utility model is not limited to the above-described embodiments. Improvements and modifications made by those skilled in the art based on the disclosure of this utility model without departing from the scope of this utility model should be within the scope of protection of this utility model.
