Abstract

936,642. Casting composite articles. NATIONAL LEAD CO. April 4, 1962 [April 18, 1961], No. 12929/62. Class 83 (1). An insert about which a metal of lower melting point is to be die-cast, e.g. a grey iron liner for an aluminium &c. cylinder block is supported in the dies by a holder on which it is shrink-fitted, the solidified casting with the insert and holder being removed from the dies and the holder withdrawn from the casting after cooling it to cause shrinkage. Fig. 4 shows a cylinder liner 21 mounted on a steel holder 20 being inserted on a core pin 26 in the ejector die part 28. Aluminium is pressure die-cast on to the insert, the support afforded by the holder preventing fracture &c. of the liner. After a period of cooling the casting together with the holder is ejected, Fig. 7. A spray head is raised into the holder, whose contraction then enables it to be pushed out of the casting by e.g. a fluid-operated ram.
