FIELD: machine tool manufacture, namely drive mechanisms to molding machines such as thermoplast molding automatic machine, possibly mechanisms for moving movable plate to position of closed mold halves.
SUBSTANCE: mechanism for closing mold halves of molding machine includes single-arm levers mounted in stationary plate and kinematically coupled with drive unit. Single-arm levers are joined with two-arm levers whose second arm is joined through intermediate links with drive unit. Said two-arm levers are mounted in mirror fashion in bearing units on movable plate in such a way that their rotation axes laid in the same plane with rotation axes of respective single-arm levers.
EFFECT: enhanced conditions for maintaining mechanism due to absence of single-arm levers in front of mold halves, simplified design of mechanism, improved reliability of mold halves closing at molding article, enhanced operational stability of the whole molding machine.
