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 car lighting systems. The parts with extremely high requirements for the appearance of automobiles are headlights, so the requirements for mold design and manufacturing are extremely high. The main lighting parts of general automobiles are front and rear headlights. Its main parts are: 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. Headlight rp parts are the main parts of the whole car, and also its main core, which can play an important role to a certain extent.

Since the mold is a large mold with a complex parting surface, the molded parts and the template adopt an integrated structure. The advantages of this structure are compact structure, good strength and rigidity, small mold volume, and avoiding frame opening, frame matching and manufacturing wedges, etc. cumbersome process. So what kind of advantages should we have in the design of this kind of parts? Let me introduce it to you next.

1. The parting surface is smooth and has no sharp corners, no thin steel, no wireless or point sealant. In general, the requirements for the parting surface of the car lamp mold are extremely high, and EDM is not required to clean the corners.

2. Design R angles for all non-forming corners, design a relatively large process R angle as much as possible, and design chamfered C angles or R angles for edges that do not participate in forming or matching on the mold. To a certain extent, it is based on the size of the mold as much as possible Design larger chamfers.

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 the insertion angle is reasonable. For medium and large molds for automobiles, the glue surface of the parts can be treated with copper blocking, and the inserts need to be designed with a 5-degree slope on both sides to facilitate mold matching and insert removal.

To sum up, the above is my preliminary understanding of this product. If you want to know more, please call our Xiehe manufacturer.
