Abstract

An injection molding machine for processing plastifiable materials includes a positioning element, a stationary mold carrier fixedly connected therewith, a movable mold carrier defining a mold tentering space with the stationary mold carrier, a closing device for shifting the movable mold carrier in a closing direction into a closed position with the stationary mold carrier, a supporting element for the closing device movably carried by the positioning element, and a clamping unit jointed to the stationary mold carrier and the supporting element at coupling points and adapted to essentially take up occurring forces and deformations and to deviate them around said mold tentering space. The clamping unit is formed of several pieces jointed to the stationary mold carrier or the supporting element at the coupling points and are coupled with each other at at least one first connecting point spaced from the coupling points.

Dependent claims

An injection molding machine, comprising:

(a) a machine base;
(b) a stationary mold carrier fixedly connected with said machine base;
(c) a movable mold carrier displaceably mounted on said machine base for movements towards and away from said stationary mold carrier to assume open and closed positions with respect to said stationary mold carrier;
said movable mold carrier and said stationary mold carrier defining therebetween a mold clamping space;
(d) force-exerting means connected to said movable mold carrier for moving said movable mold carrier into and out of said closed position and for applying a clamping force to said movable mold carrier in said closed position thereof for urging said movable mold carrier against said stationary mold carrier;
(e) a supporting element displaceably mounted on said machine base for supporting at least one part of said force-exerting means;
and
(f) force take-up means for receiving forces and deformations occurring when said movable mold carrier is in said closed position and said force-exerting means applies said clamping force;
said force take-up means comprising
(1) a first individual component being jointedly connected to said stationary mold carrier at a first coupling point;
and
(2) a second individual component being jointedly connected to said supporting element at a second coupling point;
said first and second individual components being directly articulated to one another at least one connecting point located at an essentially fixed distance from the first and second coupling points;
said first and second individual components being void of a force-transmitting connection with said machine base for isolating said machine base from forces taken up by said force take-up means.
