ABSTRACT:
Products are molded in a mold assembled prior to molding from a lower punch and a mold case arranged in coaxial relationship, the mold being subjected, in the course of charging it with the material, to harmonic vibrations whereby the material undergoes precompaction, and the subsequent compaction of the material by the combined effect of a vertical vibratory shock load and a compressive load is aided by vibrating the mold case, the vertical vibratory shock load being applied to the material via the lower punch. The apparatus for molding products according to the method of the invention incorporates power cylinders mounted on a base, with an additional crosshead being suspended by elastic members on the rods of said power cylinders, said additional crosshead being adapted to reciprocate along the columns of the apparatus, and the additional crosshead mounts vibration exciters and a mold case, whereas the vibrating frame carries the lower punch mounted in coaxial relationship with the mold case.
