AI Technical Summary
Technical Problem
In the existing technology, sheet metal beams, as supporting components, increase the manufacturing cost and weight of the workpiece and cannot meet the requirements for lightweighting.
Method used
The structure adopts an injection molding one-piece molding method. A fluid-assisted injection device is used to push the open core in the molten, unsolidified plastic material to form an irregularly shaped support tube. The position of the connecting reinforcing ribs is reasonably designed to meet the support strength requirements.
Benefits of technology
It achieves the advantages of low cost, lightweight structure and high support strength of the workpiece.

Abstract
本发明属于车辆加工设备技术领域，特指一种车辆的仪表板横梁支架加工方法，包括有加工模具，车辆仪表板横梁支架包括具有内孔的异形支撑管、以及竖向连接部与纵向连接部，竖向连接部以及纵向连接部均与异形支撑管为一体式的注塑成型结构；加工模具包括有上模板、下模板、以及上模板与下模板之间形成模腔，上模板或下膜板上开设有热流通道，上模板与下模板之间设置有流体辅助注压装置与排料装置，流体辅助注压装置的注压口内柱塞滑动有开孔芯。本发明采用注塑一体成型结构，借助流体辅助注压装置的液压推动开孔芯在熔融未凝固状态的塑性材料移动，进而形成异形支撑管，并合理设计连接加强筋位置配合、以满足工件的支撑强度要求。
