Abstract

885,436. Coating and lining moulds and cores. FONDERITE S.a.r.l. Nov. 27, 1959 [Nov. 28, 1958 ; July 7, 1959], No. 40467/59. Class 83 (1). A method of providing an exothermic lining on the interior of permanent mould comprises introducing a hardenable pourable mixture containing an exothermic material and a silicate or other binder into the space between the walls of the mould and a form and then introducing a hardening medium such as CO 2 gas, hot air, &c. at several points of the form into the material for hardening it. The method is stated to be suitable for providing exothermic linings in flasks and casting boxes. The form comprises several hollow elements 2, 3, 4, Figs. 1 and 2, connected together by hinges 5 and held spaced from the mould wall 1 by brackets 17 incorporating clamping means. The bottom of the gap so formed is sealed by a flange 13 with a sealing strip 14. Hardening gas is supplied by flexible pipes 11 and passes through holes 8 in the form elements. In a modification, Fig. 5, the form may be collapsed by supporting the elements on rack members 50 actuated by a pinion 51. The form may be supported on a central frame which is vertically adjustable by a rack-andpinion mechanism. The wall elements may also include cover-pieces which cover the interior of the form so that the lining material does not fall inside. Vibrator means may be mounted on the form. The form elements may be moved by electric motor means and controlled automatically by an electronic control system.
