[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 arranged at the top of the piston rod of the cylinder 61. The movable slider 62 is provided with a rope positioning column 63.

[0051] The product of the first mold product injection molding is used as a test product, and the rope buckle 1 and the rope hook 2 of the coat rack rope product are clamped and fixed by the rope buckle fixing component 51 and the rope hook fixing component 52 respectively. Then, the rope 3 between the two is hung on the rope positioning column 63 of the movable slider 62 through the rope winding support 53, and the cylinder 61 is started to tighten the rope 3 outward to adjust the length of the rope 3. Then, the length of the rope 3 between the rope buckle 1 and the rope hook 2 is inspected. When the length meets the preset requirements, the sliding distance of the movable slider 62 can be 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 composite preset requirements. Through the above-mentioned multiple length adjustment pre-tests, the relationship between the sliding distance of the movable slider 62 and the final length of the rope 3 can be confirmed, and then the length of the rope 3 between the rope buckle 1 and the rope hook 2 can be accurately controlled in subsequent production.

[0052] In the formal production process, referring to the above operation, after adjusting the length of the draw cord 3, the draw cord 3 is hung on the draw cord positioning column 63, the rope buckle 1 and the draw cord hook 2 are clamped and fixed by the rope buckle fixing assembly 51 and the draw cord hook fixing assembly 52 respectively, the draw cord 3 extending from the end of the rope buckle 1 is fixed by the draw cord fixing assembly 54, and the material head (i.e. the next rope buckle 1) is fixed by the material head positioning assembly 55. After being fixed, the coat rack draw cord product with the middle section draw cord 3 of uniform length and within the tolerance range can be obtained through subsequent mold closing and injection molding.

[0053] Embodiment 2:

[0058] Embodiment 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 arranged on the mold base, and a mold cavity for injection molding is formed between the movable mold 4 and the fixed mold 7. Among them, a cylinder fixing block 8 is provided on the side wall of the movable mold, and the cylinder 61 is installed 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 commonly used injection mold, and cleverly combines injection molding and length adjustment. The method of using the mold of this embodiment is:

[0061] The product after injection molding of the first mold product is used as a test product. At this time, the length of the rope 3 between the rope buckle 1 and the rope hook 2 is not precisely controlled. According to product requirements, the preset length of the rope 3 is confirmed to be 155±2mm. The rope 3 extending from the end of the rope buckle 1 is pressed under the pressure plate 542 of the rope fixing component 54, and the rope buckle fixing component 51 and the rope hook fixing component 52 are respectively buckled and fixed to the rope buckle 1 and the rope hook 2. At this time, only the rope 3 inserted in the rope hook 2 can be adjusted in length. Then, the rope 3 between the rope buckle 1 and the rope hook 2 is hung on the rope positioning column 63 of the moving slider 62. Then, the cylinder 61 is opened through the manual valve 9, and the moving slider 62 on the piston rod of the cylinder 61 begins to drive the rope 3 to stretch outward, and the sliding distance of the moving slider 62 is recorded at this time. Then the length of the rope 3 between the rope buckle 1 and the rope hook 2 is 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 fit with the limit table 42 for limiting, which can prevent the piston rod from moving and causing the sliding distance of the movable slider 62 to change, thereby ensuring that in the subsequent injection molding process, the rope 3 can obtain a uniform length of the final product as long as it is hung on the rope positioning column 63. If the measured length does not meet the preset length requirements, the sliding distance of the movable slider 62 is continuously adjusted until the length of the rope 3 meets the preset length requirements to determine the final sliding distance.

[0062] In the formal production process, referring to the above operation, after adjusting the length of the draw cord 3, the draw cord 3 is hung on the draw cord positioning column 63, the rope buckle 1 and the draw cord hook 2 are clamped and fixed by the rope buckle fixing assembly 51 and the draw cord hook fixing assembly 52 respectively, the draw cord 3 extending from the end of the rope buckle 1 is fixed by the draw cord fixing assembly 54, and the material head (i.e. the next rope buckle 1) is fixed by the material head positioning assembly 55. After being fixed, the subsequent mold closing injection molding can produce a coat rack draw cord product with a uniform length of the middle section draw cord 3 and within the tolerance range.

[0063] If the preset length of the middle 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 perform 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 to facilitate the understanding and use of the invention by those skilled in the art. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the present invention is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the scope of protection of the present invention.
