Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The invention provides a manufacturing method of an electric vehicle lamp by secondary glue pouring and injection molding, which comprises the following steps:
step one, injection molding a light guide block 1, and then embedding a light source 3 in the light guide block 1;
and step two, injection molding the cover body 2, namely placing the injection molded light guide block 1 in an injection mold of the cover body 2, and injection molding to form the cover body 2.
Further, in the first step, the inner surface of the light guide bar 1 obtained by injection molding is provided with a plurality of prism surfaces 4. In the second step, the outer surface of the cover body 2 obtained by injection molding is provided with a plurality of edge surfaces 4. The individual facets 4 are plane and are connected to one another by edges.
Further, electric motor car light that secondary encapsulating was moulded plastics, including a plurality of light guide block 1 and the cover body 2, the cover body 2 is solid translucent cover, light guide block 1 inlays through the mode that the secondary was moulded plastics in the cover body 2, the light guide block inlays in the solid translucent cover body, and the third dimension is strong, and seamless connection has strengthened visual effect between the light guide block and the cover body.
