The light rail contact line comprises a contact line assembling groove formed in the top face and a contact guiding lower protrusion arranged at the bottom, and a top opening of the contact line assembling groove is of a closing-up structure. And stable and reliable elastic contact can be realized. In addition, the invention further provides an extrusion die of the contact line. The extrusion die comprises an extrusion heating section, a forming transition section and a cooling vacancy filling section which are sequentially arranged from the feeding end to the discharging end. The extrusion heating section is provided with a heating forming cavity with a trapezoidal cross section; the forming transition section is provided with a transition forming cavity with a V-shaped section; the cooling vacancy filling section is provided with a vacancy filling forming cavity of which the section shape is the same as that of the contact line, and circular gap parts are arranged on two sides of the vacancy filling forming cavity. The processing resistance of the extrusion molding die can be reduced, so that the extrusion molding production efficiency of the contact line is improved.

    本发明公开了一种轻轨接触线,包括设置于顶面的接触线装配凹槽和设置于底部的接触导向下凸起,所述接触线装配凹槽的顶部开口为收口结构。能够用于实现稳定可靠的弹性接触。此外还提供了上述接触线的挤出模具,包括自进料端至出料端依次设置的挤出加热段、成型过渡段和冷却补缺段;所述挤出加热段设置有截面形状为梯形的加热成形腔;所述成型过渡段设置有截面形状为V形的过渡成形腔;所述冷却补缺段设置有截面形状与接触线截面形状相同的补缺成型腔,且所述补缺成型腔的两侧设置有分圆形缺口部。能够降低挤出成型模具加工的阻力,从而提高接触线的挤出成型生产效率。
