Automotive lamp moulds include front and rear headlight moulds, tail lamp lens moulds, etc. On the automotive lamp moulds, the pre-CAE analysis is used to predict the moulding pressure, and the actual moulding pressure is reduced by rationally setting the runner, and the sticking of the front mould is reduced; The headlight BEZEL, through the CAE analysis in the early stage, uses the method of adding and subtracting glue and drainage to avoid welding marks in the visible area. Since the automobile lamp mould belongs to the exterior parts, the requirements for the appearance of the product are very high, and the mould needs to be polished to the mirror surface requirements.
