摘　　要：示教工业机器人弯管卡线槽为直管+弯管形状,模具设计难点在于弯管段的脱模,塑件外壁的脱模简化为自动脱模和推杆推出方式,内壁的脱模设计了2个抽芯机构,分别是液压缸直管抽芯和液压缸弯管抽芯。在弯管抽芯机构中,先由液压缸活塞杆推动滑块直线移动,滑块再通过拉杆带动弯管圆弧滑块在摆杆和圆弧压条的共同导向下做旋转式抽芯,实现弯管内壁的旋转式抽芯脱模。The teaching industrial robot bend pipe trunking is in the shape of a straight pipe+bent pipe.The difficulty in mould design lies in the demoulding of the bent pipe section.The demould-ing of the outer wall of the plastic part was simplified to automatic demoulding and ejector pin methods.For demoulding of the inner wall,two core-pulling mechanisms driven by hydraulic cyl-inder were designed,respectively for the core-pulling of the straight pipe and for the core-pulling of the bent pipe.In the bent pipe core-pulling mechanism,the piston rod of the hydraulic cylinder pushed the slider to move linearly first,and then the slider driven the bent pipe arc slider through the tie rod to perform rotary core-pulling under the joint guidance of the swing lever and the arc pressure strip,which realized the rotary core-pulling demoulding of the inner wall of the bent pipe.
