Key points for attention in the design of injection molds for headlight optical lens:
Auto light optical thick-wall lens is a kind of lens with special optical properties.
In the field of car lights, thick-walled lenses are mainly used to manufacture high beams, low beams, turn signals and other parts. Compared with ordinary lenses, thick-walled lenses perform better in terms of protecting headlight light sources, reducing glare, and improving clarity and hit rate. In the field of LED lighting, thick-walled lenses are often used in external lighting facilities such as street lights. The selection of materials and the design of optical characteristics can achieve different lighting effects and energy-saving goals.
In addition, in the field of furniture and indoor lighting, thick-walled lenses can be used as the shell of decorative lamps to achieve different lighting effects and atmosphere adjustments through different shapes and colors, improving user comfort and visual experience.
Therefore, as a special optical element, thick-wall lens has important application value in different fields, and its application will continue to expand and deepen with the continuous development of science and technology.
The influence of the material: the low temperature of the melt prevents the fusion of the flow front, and the poor fluidity of the molten liquid makes the flow front confluence
Weld marks will be generated if the joint angle is smaller than the material fusion angle.
The product design should try to avoid structures that are prone to material flow divergence, and appropriately increase the wall thickness at the position where weld lines may occur
It is conducive to melt fusion and improves the welding strength; add exhaust grooves at appropriate parts to avoid melting due to poor mold exhaust.The filling of the body is not smooth; the number of gates and the position of the gates should be reasonably designed to avoid excessive temperature drop of the forward material flow caused by the process being too long.Avoid welding lines in important places
1.Optical thick wall lens moldphenomenon
2.Optical projector lens moldtheory
The theoretical basis obtained from the above is that there is a certain gap between the plastic and the plastic during the feeding stage, which is brought into the barrel after being sheared by the screw. During the shearing process of the screw, physical changes will occur inside the material, from a glass state to a high elastic state, from a high elastic state to a viscous fluid state.
The process of this change may only be between a few seconds to tens of seconds. (Depending on the size of the machine or the product), it is necessary to change a complex process in such a short period of time, and injection defects will also occur immediately. The gap between the plastics is compressed to the inside of the melt to generate gas. If the gas cannot be discharged to the outside of the barrel during plasticization, the existing gas will be wrapped in the melt and injected into the mold cavity. Whether the mold can be discharged smoothly depends on whether the exhaust of the mold is good.
Obviously, white mist is also a phenomenon of trapped air. Many people engaged in injection molding technology mistakenly believe that only burning is the trapped gas, or that it is unscientific to open the exhaust groove when trapped gas occurs. Burning is caused by excessive trapped gas. The gas is compressed under high pressure and high speed and cannot be released, resulting in local combustion. The combustion temperature can reach 600-800°C in an instant, which is the highest state of trapped gas.

How can the gas be best discharged without producing white fog?
1.Optics lens mold
Exhaust is not completely solved by the mold. Regarding the characteristics of PP material, the temperature range is very wide, and its flow performance is excellent. If the exhaust groove of the mold is too large or the position is wrong, it will not be exhausted correctly, and it is easy to cause flash defects, so correct exhaust is useful.
2.Optical projector lens moldprocess
Mastering the correct tuning skills is very effective in actual work.
1) If the rotation speed of the screw is reduced, the temperature of the melt can be made uniform, and the chance of entrained air is small. If the screw rotates too fast, the chance of entrained air is more; the melt is subject to the shear force of the screw, frictional heat causes the temperature of the melt to be uneven, and the melt decomposes to generate gas.
2) Increasing the mold temperature can benefit high pressure and slow filling to gain time. If the mold temperature is too low, the surface of the product is prone to premature freezing, and slow filling cannot be achieved, which may lead to lack of glue.
3) Reduce the injection speed, the faster the speed, the faster the gas is compressed and the higher the temperature. The slower the speed, the slower the gas is compressed, and the easier it is to discharge the gas.
4) Clamping force, the greater the clamping force, the worse the exhaust effect on the cavity surface, and the smaller the clamping force, the better the exhaust effect on the cavity surface.
