Composite injection moulding tool - assembled with through bores, guide bushes and guide or clamping bolts

摘要

Tool consisting of several parts has centring bores to locate their mutual disposition. The centring bores pass through several component at a dia. equal to that of the centring bushes. The bushes, inserted into them for the fixing bolts and dowels, have fitments to facilitate their extraction. The individual components need not be turned in the case of through holes so that errors caused thereby are eliminated. The bushes can now be readily extracted without damaging them.
