具有多抽芯机构的转向器壳体压铸模设计

Design of Die-casting Die for Steering Gear Housing with Multi Core Pulling Mechanism

对总体尺寸较长且多个不同方位存在孔位的管状零件,在压铸模设计时,分型面的选择及成型部分的分割将决定抽芯机构的数量及抽芯方式。转向器壳体压铸模采用了过中心线的平面分型,布置了2个液压抽芯机构及4个机动斜导柱抽芯机构,简化了模具结构,实践证明,该方案合理可行。

For tubular parts with long size and multi-direction hole,selection of parting surface and the division of the molding part will determine the number of core pulling mechanism and the core pulling method.In the design of die-casting die,the mould of the steering gear housing adopts the plane parting along the center line.The layout of two hydraulic core pulling mechanisms and four mobile inclined guide columns core pulling mechanism can simplify the structure of the die.The practical production verifies that the scheme is reasonable and feasible.
