The invention discloses a manufacturing process of an electric vehicle rear clothes rack, and relates to the technical field of electric vehicle production. The method comprises the following steps that firstly, iron blocks are smelted; 2, the smelted materials are poured into a mold for casting; thirdly, the cast rear clothes rack is subjected to rough grinding; 4, the rear clothes rack subjected to rough grinding is subjected to a flash and burr removing process; and 5, the polished rear clothes rack is detected. According to the back hanger casting device, the situation of insufficient casting caused by cooling of the back hanger can be reduced by increasing the back hanger casting speed, so that the strength and the production efficiency of the back hanger are improved, and the quality of the back hanger can be improved by polishing the surface of the back hanger. And electrostatic painting is carried out on the surface of the rear hanger, so that painting on the surface of the rear hanger can be uniform, the situation that the rear hanger needs to be painted is reduced, and the production efficiency of the rear hanger is further improved.

    本发明公开了一种电动车后衣架的制造工艺,涉及电动车生产技术领域。本发明包括如下步骤:步骤一:将铁块进行熔炼;步骤二:将熔炼后的材料浇铸进模具内,进行铸造;步骤三:将铸造完成的后衣架进行粗打磨;步骤四:将粗打磨后的后衣架进行去飞边毛刺工艺;步骤五:对打磨完成的后衣架进行检测。本发明能通过提高后衣架浇注的速度,减少后衣架冷却导致浇铸不足的情况,从而提高后衣架的强度、生产效率,本发明通过对后衣架表面进行打磨,能提高后衣架的质量。通过对后衣架表面进行静电喷漆,能使后衣架表面的喷漆均匀,减少了后衣架需要补漆的情况,从而进一步提高了后衣架的生产效率。
