Modelling and Analysis of Collapsible Core
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 7
Abstract
Those for larger pipes are custom designed. The objective of this research was to fully automate the design procedure which, for PVC pipe fittings is laborious and error prone at present. This paper discuses the design of the four key geometrical features of a two stage, lever-actuated collapsible core namely, the number of segments during demoulding, the minimum angle of taper of the grooved undercut to permit the segments to retract during demoulding and the preventation of interference between moving components. After the key geometrical features are established, it is the possible to fully automate the design of two- stage, lever-actuated collapsible core in a CAD system. The time required to design these moulding tools has been drastically reduced in the plastic injection moulding company with whom this research was jointly undertaken. And mainly we designed this product in PRO- E software. At the time of manufacturing process also we are doing in the industry of spy reddy Nandi pipes product. So this is called as multi usage product. This is a two stage collapsible core for injection moulded plastic parts with internally.
