Embodiment Construction

[0027] The present application will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present application, but do not limit the present application in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present application. These all belong to the protection scope of this application.

[0028] Such as figure 1 Shown is the structure diagram of the existing automotive LENS light guide strip, which structure includes three gates, gate 1, gate 2 and gate 3. The car LENS light guide strip weighs 27.4g, of which the net weight of the product is 14.3g, and the weight of the three gates is 13.1g. Among them, the weight of the first gate, ie gate 1, is 3.5g, 9.5cm in width and 58.5cm in length.

[0029] The second gate, Gate 2, weighs 2.5g, is 44cm long and 11.5cm wide.

Abstract

The invention discloses a car LENS light guide strip. The light guide strip structure is only provided with two pouring gates, the light guide strip is prepared through an injection molding process, machine equipment is Demag model specification 280T, the material is PC2407, the die cavity number is 1*1, and the product total length is 520 mm. The light guide strip structure is improved, one glue inlet point is omitted, the product is of a two-point glue inlet structure, through process optimization, under the condition of ensuring product normal stability, the product size and weight are controlled, and due to product surface combination lines, the product surface effect is better. Meanwhile, the number of machining procedures is reduced, work efficiency is improved, and the raw material control cost is reduced.

Description

technical field [0001] The present application relates to an injection molding process, and in particular, the present application relates to an automotive LENS light guide strip. Background technique [0002] The ambient light is composed of wires, circuit boards, LED lights and light guide structures. The lighting principle of mainstream ambient lights is that the light source transmits light to the required illuminated surface through the light guide structure, and forms diffuse emission through the skin texture on the illuminated surface. Transmits light to the human eye for an ambient light effect. Generally, LENS light guide strips are added for light guide, and injection LENS is used to complete the light guide effect through assembly. The existing product structure state is three gates. The product structure of this type of light guide strip is difficult to process, and the wall thickness of the gate is large. In addition, it is also necessary to control the weight...
