FIELD: devices for manufacture of products of polymeric materials and compositions based on them, applicable in chemical industry for production of construction mould. SUBSTANCE: the die head has a detachable body with a cooling system. The body accommodates mandrel holders and mandrels, as well as molding grooves of profiled outline for polymer. The ducts communicate with the head feeding duct. The body is made of two rectangle-section sections. The upper section has a triangle-shaped longitudinal recess with a right angle at the vertex. The lower section has a parabolic-shaped recess. Transverse lenticular grooves are provided in the sections for installation of two mandrel holders with a cross-section of a convex symmetrical lens. EFFECT: saving of material and prevented dig-in zones in the head. 5 dwg
