Abstract

In this paper, it is illustrated automobile carburetor components ?a?a4 plastic mold design program. All of the manufactures, subassembly were sculpted 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 two 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 plastic 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. 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.
