Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamp processing, in particular to a demoulding structure of a vehicle lamp mould. Background Art

[0002] Moulds are various moulds and tools used in industrial production to obtain the required products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, moulds are tools used to make moulded objects. This tool is composed of various parts, and different moulds are composed of different parts. In the production process of car lights, most plastic parts need to be produced by mould injection. After the car lights are injection moulded, they are pushed out by the ejection column. However, when the ejection column pushes the car lights, the temperature of the finished product is high because the car lights have just been injected, which makes the surface of the car lights easy to stick to the injection mould. Under the direct push of the ejection column, it is very easy to cause damage to the demoulded car lights, thus forming defects and affecting the quality of the car lights. For this reason, we propose a demoulding structure for car light moulds. Utility Model Content
