１引言在压铸模设计中，常常会遇到侧型芯抽拔机构难以布置的情况。但是利用下面介绍的斜面（燕尾）导滑机构改变抽芯方向后，模具结构就变得相对简单了。２斜面导滑机构简介如图１所示，斜面导滑机构由型芯与拉杆组成，抽芯方向与分型面成β角。如果沿β角方向抽芯，油缸的安 1 Introduction In die-casting mold design, often encountered side core pulling mechanism difficult to arrange the situation. However, using the ramp (dovetail) guide mechanism described below to change the core pulling direction, the die structure becomes relatively simple. 2 ramp guide mechanism briefing shown in Figure 1, the ramp guide mechanism consists of core and rod composition, core direction and the parting surface into β angle. If the core along the β-angle direction, cylinder safety
