Hollow special-shaped product manufacturing device and method utilizing intelligent air bag for guiding

摘要: The invention discloses a hollow special-shaped product manufacturing device and method utilizing an intelligent air bag for guiding, belongs to the field of high polymer material machining forming. is mainly composed bag, integrated sensor, storage cavity, both-direction variable displacement motor, overflow valve, calculator, closing switch, pressure gage, gas channel, extruder, fused runner, blank die head, fusion cut-out device, blow molding die, connecting pipe inflation deflation switch. In above extrusion technology used as basic forming manner, defects that on basis injection at present, cost high, one-time not easy are overcome; inner cavity size surface quality precisely controlled, water filling rubber sleeve easily controlled low in precision time short, principle simple; due multi-cavity structure, shape structure can be implemented regulated guaranteed, appearance uniformity consistency guaranteed.
