MACHINE FOR MANUFACTURING CONCRETE PRODUCTS Russian patent published in 1997 - IPC

FIELD: manufacture of building materials. SUBSTANCE: invention provides movable vibratory shaping machine for manufacturing building blocks, wall partitions, footway slabs, etc. distinguished with simple, reliable, and durable structure with small weight and minimal number of parts. Machine is easy to manufacture and operate. It ensures high-quality shaping of products with high output, and also allows quickly replacing molds 5 with punches 20 and changing assortment of products. All advantages of machine are achieved owing to updating: mechanism of vertical displacement of molds and punch; mechanism for locking and adjusting extreme horizontal positions of die; mechanisms of locking upper and lower positions of die, respectively. New mechanisms improved interaction between mold and levers and minimized number of operator's moves and effort. EFFECT: 10-12% increased productivity and 3 times increased reliable operation time. 6 cl, 11 dwg
