As a result,a mould with double stripper mechanism was needed,that is to say,there were levers and ejector pins on the stationary mould half and ejector pipes on the moving mould half.

Taking the case of ABS flash cover for example, the design and characteristics of double stripping mechanism of plastic part in the moving mold and stationary part of mold in injection moulding are discussed.

A bidirectional stripping mechanism was used to make the plastic part stripping from both fixed half and moving half.

Over the forming process analysis to plastic parts of water receiver, a feasible mold design project is provided, and a kind of demoulding mechanism of dual-slanting sliders is designed, which solves the technical problems of demoulding difficulty in lifting ear of plastic parts.

Development of two-step demoulding mechanism at side slide block of injection mould;

Using the self setting resin sand to clean the inner surface instead of sodium silicate sand can hugely shorten the time of whole demoulding course,improve work efficiency and decrease working strength.

In consideration of the difference between two parts,insert blocks on moving half and fixed half were combined;and the compounded core-pulling of slanted pushing rod,dog-leg cam and slide block was applied to finish the demoulding of internal and external side concave.
