Abstract: Four kinds of small and nimble core drawing mechanism for injection mould of case type plastic items are introduced in details.
Key words: injection mould, core drawing, sliding block
Case type plastic items play an important role in the production of modern plastic-electronic items. In general, knots sometimes together with a bolt are used to enhancer and smooth the surface of the electronic products. A mould often holds several work pieces, and core drawing is used many times in just one work piece. If we use traditional outside slanting pillar or inside slanting slide block in core drawing, the mechanism of the mould would be plicated. In practice,

according to the property that the stroke of core drawing of plastic items is very short, several kinds of core drawing mechanisms are designed as follows.
1 Outside core drawing mechanism
Outside core drawing mechanism as in is similar to traditional slanting pillar core drawing mechanism, Because of the short stroke of core drawing, slanting pillar
