MOLDING DIE Russian patent published in 1994 - IPC

FIELD: production of parts from plastics. SUBSTANCE: plates of each mold split are provided with tie-rods 5 and 16 disposed on outer surfaces and engageable with brackets 8. Brackets have spring-loaded rollers, which are in contact with rectangular openings of tie-rods 5 and 16, and loop with slot 17 for receiving fingers 18. Required succession of molding die splitting (by means of tie-rod 5) or connection of mold splits (by means of tie-rod 16) may be gained by controlling spring force applied to rollers and by regulating length of tie-rods 5 and 16. Extent of mold splits opening may be regulated by restricting slot length in loops. EFFECT: increased efficiency and enhanced reliability in operation. 5 dwg
