    摘要： A method of attaching a mold releasing agent to a molding die, a molding apparatus and a molding die therefor are disclosed. A fixed die (11) of the molding die (1) is connected to the nozzle receiving surface of a molding cavity (10) facing a material supplying nozzle. The mold releasing agent is attached to the material contacting surface (100) of the molding die (1) in such a manner that the fixed die (11) and a movable die (12) are arranged in opposed relation to each other with a gap therebetween less than a distance which allows release of a molded product, and under this condition, the mold releasing agent is supplied to the material contacting surface (100) through the gap between the material supplying nozzle (31) and the nozzle receiving surface (131).

    摘要： An improved method of machining slots and material feed holes in a molding die such as an extrusion die designed to form a honeycomb structure of ceramics employed as a catalyst carrier of a catalytic converter for automotive vehicles. In one of the preferred embodiments, shallow holes are drilled in a die material and subjected to electrochemical machining to remove material from the bottoms of the shallow holes so that they communicate with the material feed holes without any burrs. In the other embodiment, the slots are cut using a rotary cutter in a given order which will balance reaction forces exerted on the cutter from both side walls of each slot to minimize deformation of the cutter during cutting of the slots, thereby preventing the slots from being curved undesirably.

    摘要： A metal mold for molding a hexagonal honeycomb structure, having feed holes for feeding a material, pool grooves formed in the shape of a triangular lattice and communicated with the feed holes, and slit grooves formed in the shape of a hexagonal lattice and communicated with the pool grooves. Each hexagonal lattice of the slit grooves is so formed as to come into agreement with a hexagon shaped by combining six triangular lattices of the pool grooves.
