METHOD AND DEVICE FOR HOT MOULDING OF PRODUCTS OF POWDERED MATERIAL (ALTERNATIVE EMBODIMENTS) Russian patent published in 1999 - IPC

FIELD: building industry, applicable for manufacture of high-strength concrete and reinforced-concrete products. SUBSTANCE: in the method for hot moulding of products of powdered material by dies moulding of loosely filled powdered material between the readily deformable separating wall and greased moulding die transferring heat is accomplished by loading the intermediate medium by the tapered surface of the loading die, when it moves in the duration perpendicular to the direction of moulding, towards the vertex of the taper angle of the die tapered surface. The device has a moulding die with heating elements, loading die in the form of a tapered yoke, intermediate powder medium, separating readily deformable wall. Gas- discharge ducts are made in the insert base. A guide surface is made in the lower part of the loading die. The inner surface of the loading die upper part is step-wise conjugated with the tapered surface of the lower part. The heating elements may be installed on the outer surface of the moulding die. EFFECT: reduced power consumption, specific consumption of materials, enhanced capacity. 4 cl, 2 dwg
