VERTICAL INJECTION MOLDING MACHINE

摘要

An injection molding machine (10) with a vertically operating clamp mechanism (12) is provided with a pair of locking devices (75) on the upper movable platen (15) to lock the locking rods (40) for high tonnage clamping forces. Each locking device uses spring biased actuating rods to simultaneously lock two locking rods to the movable platen in an always "on" arrangement. A power on actuator (36) is provided to release the locking device for raising and lowering the movable platen. A vertical ladder frame (62) is provided for guiding the movable platen when it is raised or lowered. Additionally, a lift mechanism (108) is provided for a rotary table (120) carrying the lower mold halves.
