2、滑杆来完成，当斜滑杆充当顶杆向上推出塑件时，由于斜度的作用，斜滑杆同时水平方向平移一个距离，即为侧向抽芯距，它们用来完成零件底部的侧孔。关键词关键词: 塑料模具；UG 标准件；侧向抽芯；性能尺寸要完整的说明书和图纸请联系 QQ778672454另外本人甩卖全部机械毕业设计 5 元一份（全部甩卖）AbstractIn this paper, it is illustrated automobile carburetor components 4 plastic mold design program.

3、ted by UG software. Based on the analyses of manufacture, the project was chosen, the techniques and dimension was accounted, and the assemblage of mold subassembly was finished. The machining problems were calculated. Inset parts, oblique-glide-pole were joined in the mold. The die is depart into t
4、wo times, which is depart at the above and below of the middle plate. The first discretion made the plastic condensate separate from the die, finish the lateral core pulling of the completion die. The second discretion is finishing the bottom side of the hole, at the same time putting out the plasti
5、c part. The side core which in the staying part of the die is drive by slanting oriented pole, the slanting oriented pole bring the side-core machine of the middle sub-plate moving to take out the core, then molding the barrel of the part; pulling the core of the convex die is by oblique-glide-pole.
6、 The oblique-glide-pole as a pusher to push up the plastic part, because of the role of the pitch, at the same time the oblique-glide-pole move a distance which is the core pulling distance from the lateral, with these to finish the side hole which on the bottom of the plastic part.Keywords: plastic
