Abstract

The invention relates to the field of new-energy car design, in particular to a new-energy car lamp base and a manufacturing method thereof. An X2 demoulding mechanism, an X3 demoulding mechanism andan X4 demoulding mechanism solve the technical problem that an oblique core pulling mechanism of the movable die side is arranged to interfere with a mould ejector mechanism, and the car lamp base hasthe beneficial effects that by the adoption of a steering mechanism, a mould plate is used for carrying out driving, the mould structure is simplified, and the design difficulty of the demoulding mechanism is reduced. According to the new-energy car lamp base manufactured through a mould, the forming precision and the structural strength are improved greatly.

Description

Technical field [0001] The invention relates to the field of new energy vehicle design, in particular to a new energy vehicle lamp holder and a manufacturing method thereof. Background technique [0002] In the prior art, in technical fields that require lights, such as new energy vehicles, night cruise drones, aviation airplanes, and bicycle lighting fields, lamp holders for installing lights are used. Especially, in the field of new energy vehicles, the structural design of the front and rear lamp holders belongs to a large-scale and complex structure in the automotive plastic parts, especially the structural design of the front lamp holder. Due to the particularity of its installation position, on the one hand Limited by the shape of the lampshade shell, and on the other hand by the space of the engine compartment, the structural features of the front lamp holder products are mostly special-shaped structural features; the special-shaped structural features on the product are d...
