Problems solved by technology

However, in this method, since the ends of the rope ends are not fixed, it is easy to produce deviation during the injection molding process. If the deviation is too large, the side wall of the plastic layer will be too thin, which will affect the quality of the product, and even the rope will be exposed to the Plastic layer and form waste

Embodiment 1

[0056] An injection-molded rope head, which is a high-hardness product, such as Figure 1-3 As shown, it includes a black rope and a transparent plastic layer. The total length is 1100mm, and the length of the plastic layer is 40mm. It has a smooth and transparent surface. The cut surface of the rope is flush with the end of the plastic layer.

[0057] Prepared by the following method:

[0058] (1) Ingredients:

[0059] Weigh the raw materials with the weight ratio of plastic raw materials: functional additives = 100:5, mix them evenly in the mixer, and then complete the batching, and obtain the injection molding raw materials. If it is 80D, add the injection molding raw material into the hopper of the machine and set it aside.

[0060] Among them: the plastic raw material is styrene-acrylonitrile copolymer, its Shore hardness is 80D, and its density is 1.06~1.08g / cm 3 , transparency 88% to 92%, refractive index 1.57.

[0061] The functional additive is polyperfluoroethyle...

Embodiment 2

[0070] An injection-molded rope head, which is a high-hardness product, such as Figure 4-Figure 6 As shown, it includes a black rope and a transparent plastic layer. The total length is 1100mm, and the length of the plastic layer is 40mm. It has the effect of smooth surface, transparency and end sealing.

[0071] Prepared by the following method:

[0072] (1) Ingredients: Same as in Example 1, the peeling force between the plastic end seal and the section formed by the injection molding raw material is 6N / 25mm.

[0073] (2) traction positioning: same as embodiment 1.

[0074] (3) Injection molding: the same as in Example 1.

[0075] (4) Cutting:

[0076] Use an automatic beer cutting machine to cut the plastic layer and the rope body at a distance of 1-1.5 mm from the end of the plastic layer.

[0077] (5) Glue filling and sealing:

[0078] Put the above-mentioned rope end with 1-1.5 mm of plastic layer cut off into the mold cavity again, and form a plastic sealing part ...

Embodiment 3

[0080] An injection-molded rope end, which is a medium-hard product, such as Figure 7-Figure 9 As shown, it includes a black rope and a solid-color plastic layer of luminous powder. The total length is 1100mm, and the length of the plastic layer is 40mm. It has the effect of smooth surface, luminous and loose ends.

[0081] Prepared by the following method:

[0082] (1) Ingredients:

[0083] Weigh the raw materials with the weight ratio of plastic raw materials: functional additives: processing additives = 100:1:0.1, mix them evenly in the mixer, and then complete the batching to obtain injection molding raw materials. The peeling force of the injection molding raw materials and ropes after bonding It is 4N / 25mm, put the injection molding raw material into the hopper of the machine, and set it aside.

[0084] Among them: the plastic raw material is polyethylene, its Shore hardness is 45D, and its density is 0.86~0.96g / cm 3 .

[0085] The functional additive is luminous po...

Abstract

The invention discloses an injection molding rope head and a preparation method thereof, belonging to the technical field of clothing accessories. The preparation method comprises the following steps: distributing, namely, collecting and mixing a plastic raw material, a pigment, a functional additive and a processing additive; pulling and locating, namely, enabling a rope belt to penetrate through rope penetrating holes in two ends of a mould cavity, respectively applying a pull force to two ends of the rope belt, keeping a tightening state of the rope belt, and enabling the diameter of the rope belt to be consistent with that of the rope penetrating holes after being tightened and pulled; injection-molding, namely, injecting an injection raw material into the mould cavity, carrying out injection-molding to form a plastic layer coated on the periphery of the rope belt; shearing, namely, cutting the rope belt at a preset position, and forming the rope head coated with the plastic layer. The preparation method and the prepared injection molding rope head thereof are capable of keeping the rope belt to be in a center position in a plastic part, and ensuring no rubber overflow on a contact place of an injection molding part and the rope belt and ensuring the integrity of the rope belt. Meanwhile, the injection molding rope head is capable of realizing adjustment of hardness, handfeel, functions and effects and colors as well as appearance effects of tail end blocking, tail end flushing or tail end loosening.

Description

technical field [0001] The invention relates to the technical field of clothing accessories, in particular to an injection molding rope head and a preparation method thereof. Background technique [0002] Rope products are widely used in clothing, shoes and hats, and are a common type of clothing accessories. However, the style and function of the common rope head products in the market are relatively single, and they are generally only used to realize the tightening of clothes, and it is difficult to play a decorative role. [0003] With the improvement of people's aesthetic requirements for clothing, traditional accessories are increasingly unable to meet people's aesthetic needs. People also use injection molding to cover the outside of the rope head with plastic to enrich the appearance and feel of the rope head product. [0004] However, the conventional injection molding method is to first cut the rope body to form a rope with an end, and then put the end of the rope...
