Claims

[Scope of utility model registration request]

In a mold clamping safety device for an injection molding machine or die casting machine equipped with a safety gate, a stopper block is provided with a through hole in the mold clamping direction in the fixed plate or toggle plate, and one or many arcuate grooves are provided on the shaft. and a safety rod having one end fixed to a support provided on the movable platen and the other end passing through a through hole in the stopper block and moving forward and backward in synchronization with the movement of the movable platen using the through hole as a guide. , 1 at a position corresponding to the center of the arcuate groove of the safety rod in a direction perpendicular to the longitudinal direction of the safety rod with one end inserted into the stopper block in order to engage and disengage from the arcuate groove of the safety rod; A shaft having a flat surface on a part of its outer periphery, a link provided with rollers at both ends and whose intermediate part is attached to the other end of the shaft, and movement of the safety rod and safety gate to rotate the link. Accordingly, there is provided a mold clamping safety device comprising a dog provided so as to engage with each of the rollers.
