Car lights are mainly used for lighting, which can be said to be the eyes of the car. Car lights are a general term for all automotive lighting systems. The parts with extremely high requirements for automobile appearance are car lights, so the requirements for mold design and manufacturing are extremely high. The main lighting accessories of a general car are the front and rear headlights. Its main parts include: left and right lenses, left and right decorative frames, left and right lamp housings, left and right reflectors, etc. The appearance requirements of automobile lights are extremely strict. Car light parts are the main parts of the entire car and its main core. They can play an important role to a certain extent. Since the mold is a large mold with complex parting surfaces, the molded parts and template adopt an integrated structure. The advantages of this structure are compact structure, good strength and rigidity, small mold volume, and avoids the need for opening frames, mounting frames, and manufacturing inclined wedges. Cumbersome process. So what advantages should we have in designing this kind of parts? Next, let me introduce it to you.

1. The parting surface is smooth and has no sharp corners, no thin steel, no wires or spot sealant. Under normal circumstances, the requirements for the parting surface of car lamp molds are extremely high. EDM does not need to clean the corners, and the parting surface is not prone to burrs, and the built surface is not allowed to wrinkle.

2. Design R angles for all non-forming corners. Try to design as large a process R angle as possible. Edges on the mold that are not involved in molding or matching must be designed with chamfered C or R angles. To a certain extent, this is based on the size of the mold as much as possible. Design a relatively large chamfer.

3. Optimize the plastic parts if necessary. When designing the parting surface, try to simplify the mold processing. The parting surface made has no thin steel, no sharp corners, and a reasonable insertion angle. For medium and large automobile molds, the glue surface of the parts can be blocked with copper, and the inserts need to be designed with a 5-degree slope on both sides to facilitate mold matching and assembly and disassembly of the inserts.

In summary, the above is the editor’s preliminary understanding of this product. If you want to know more, please feel free to call our Xiehe manufacturer.
