The invention provides a suspension bushing forming die, a suspension bushing and a vehicle. A die core of the suspension bushing forming die is provided with an expansion core arranged on a lower die plate and a positioning pin arranged on an upper die plate. Wherein the expansion core is made of spring steel and is provided with a positioning hole into which the positioning pin is inserted. The inner pipe of the suspension lining can be arranged outside the expansion core in a sleeving mode, the positioning pin can be inserted into the positioning hole and extrude the expansion core to expand in the radial direction, the expanded expansion core can abut against the inner wall of the inner pipe and be disengaged from the positioning hole along with the positioning pin, and the expansion core can contract and reset in the radial direction. According to the suspension lining forming mold, after the inner pipe is arranged outside the expansion core in a sleeving mode, the positioning pin is inserted into the expansion core, the expansion core is extruded to expand in the radial direction, and the expansion core abuts against the inner wall of the inner pipe, so that the expansion core has supporting force on the inner pipe in the radial direction of the expansion core, pressure generated in the glue injection process can be prevented, and the inner pipe is prevented from being extruded to deform; therefore, the production yield of the suspension bushing forming die can be improved.
本发明提供了一种悬置衬套成型模具、悬置衬套及车辆,该悬置衬套成型模具的模芯具有设于下模板上的涨芯,以及设于上模板上的定位销。其中,涨芯采用弹簧钢制成,并具有供定位销插入的定位孔。悬置衬套的内管能够套设在涨芯外部,定位销能够插入定位孔,并挤压涨芯径向扩张,扩张后的涨芯能够与内管的内壁抵接,且随定位销脱出定位孔,涨芯能够径向收缩复位。本发明所述的悬置衬套成型模具,可在内管套设在涨芯外部后,通过定位销插入涨芯,挤压涨芯径向扩张,而使涨芯与内管的内壁抵接,由此可使涨芯对内管具有沿其径向的支撑力,能够防止注胶过程中产生的压力,挤压内管变形,从而可提高悬置衬套成型模具的生产良率。
