Embodiment

[0018] Embodiment: The present invention provides a kind of LED lamp lens injection molding process, and this production process comprises the following steps:

[0019] (1) Development and design of injection mold: the mold core is smooth, and the product needs to have a refraction effect during mold design to meet the optical transmittance and spot requirements of the car light, so that the lens-type lamp head has uniform brightness and strong penetrating power;

[0020] (2) Selection of injection molding raw materials: PC raw materials mainly have good impact and transparency, good mechanical properties and insulation properties, wide service temperature, and high dimensional stability;

[0021] (3) Selection of injection molding machine: buy the original imported injection molding machine, and use the original imported electroplated optical grade screw;

[0022] (4) Injection molding process: 1. Drying treatment of raw materials; 2. Preheating treatment of injection molding...

Abstract

The invention discloses an injection-molding process for an LED automobile lamp lens. The production process comprises the following steps of: (1) developing and designing an injection mould; (2) selecting models of injection molding raw materials; (3) selecting a model of an injection molding machine; (4) performing injection molding process; and (5) performing product de-molding and automatic making. Plastic is used to make an automobile lamp, so that light is effectively and uniformly scattered, and therefore, light condensation ability is relatively strong; brightness of a lens type lamp holder is uniform, and penetrating power is strong; and light dispersion is slight, light range is long and definition is high, so that a user sees a thing in the distance at a first time, and therefore, the user is prevented from passing an intersection or missing an object.

Description

technical field [0001] The invention relates to the technical field of LED car lamp lens production, in particular to an injection molding process for LED car lamp lenses. Background technique [0002] LED car light lens injection molding is a method of advanced injection molding production; products are molded by low-speed high-pressure precision injection molding; LED car light lens injection molding is realized through precision injection molding machines and precision molds. Existing glass car lights have defects such as relatively poor elasticity, relatively heavy quality, relatively poor transparency, and relatively poor mechanical properties. [0003] Therefore, how to design an injection molding process for LED car light lenses has become a problem we need to solve at present. Contents of the invention [0004] The present invention provides an LED lamp lens injection molding process that can effectively solve the above-mentioned problems in the background technol...
