A centrifugal integral cast
metal mould for dual-tray
flange straight pipes comprises a left tapered plug tray, a through-wall
flange pipe borne mould, fastening bolts, a non-through-wall
flange pipe mould, a wedge, a fitting pin, a resin sand withdrawal core, a transition section
pipe mould and a right tapered plug tray; the resin sand withdrawal core is connectively mounted between the through-wall flange pipe borne mould and the non-through-wall flange pipe mould through the fastening bolts, the through-wall flange pipe borne mould and the transition section pipe mould are connected through the fastening bolts, the transition section pipe mould and the non-through-wall flange pipe are connected through the fastening bolts, and the resin sand withdrawal core is connectively mounted between the non-through-wall flange pipe mould and the right tapered plug tray through the fastening bolts. By the arrangement, the mould is combined and assembled in design, requirements of different through-wall flanges on position are met,
mass production can be realized through horizontal centrifugal
casting, market requirement is met, environment protection is facilitated, dust can be fully recycled, environment friendly
casting is truly realized, and the centrifugal integral cast
metal mould is applied to the technical field of centrifugal
casting.
