The utility model relates to a molding die for a headlight decorative ring of an electric vehicle, which is characterized in that a clamping slider is arranged in a core insert, the clamping slider and the core insert are provided with a back-off insert, a die cavity is formed among the back-off insert, the clamping slider, a core plate and a cavity plate, during injection molding, plastic raw materials are injected into the die cavity from a gate of the die to form the headlight decorative ring with back-off and clamping, during demolding, the power of the injection molding machine drives the core plate and the cavity plate to open the die, the core insert and the headlight decorative ring move along with the core plate, and during the demolding, the headlight decorative ring is completed by lifting the core plate out of the die from the back-off insert under the reverse force due to the fact that an oblique guide rod is connected under the cavity plate and does not move, the clamping slider is driven to translate inwards through the cooperation of the oblique guide rod, so that the clamping core is pulled out from the clamping part and then the die is opened continuously, the ejector pin bottom plate is propped against a push rod of the injection molding machine. This scheme adopts built-in slip internal extraction structure, makes the buckle deviate from smoothly, and in the drawing of patterns in-process, and the back-off inserts motionless, compares with traditional mould, and the structure is compacter, and the drawing of patterns action reduces, and the action is more stable, and life is longer than oblique ejector pin to the oblique guide arm, has effectively improved production efficiency.

According to the electric vehicle headlamp decorative ring forming die, the guide sliding groove is formed in the core insert, the guide sliding plate is arranged on the buckle sliding block, and the guide sliding plate is matched with the guide sliding groove, so that the buckle sliding block slides smoothly.
