Abstract
In a mold closing unit for use in an injection molding machine for processing synthetic materials arranged on a mounting surface an electro-mechanical drive is applied in a toggle mechanism, at which the driving unit is movably held. The electro-mechanical drive converts a rotational movement of a driving unit into a linear movement for the toggle. The length of the lever and the length of the driving element is less than the distance from the mounting surface to the link points. A quill motor can be provided as a driving unit. This arrangement allows that the linear drive and the mold closing unit can be of a shorter and more compact construction.
Claims9
A mold closing unit for use in an injection molding machine for processing synthetic materials, comprising:
- a stationary mold carrier;
- a movable mold carrier forming with said stationary mold carrier a mold clamping space therebetween;
- a toggle mechanism having two levers connected together, one end of said toggle mechanism being jointedly connected to said movable mold carrier for moving said movable mold carrier along a closing direction and into and out of a closing position with said stationary mold carrier;
- a supporting element for supporting said toggle mechanism and being connected to another end thereof;
- and
- an electro-mechanical driving unit arranged transverse to the closing direction, and comprising a quill motor, and a driving element for driving said toggle mechanism, said driving element comprising a ball rolling spindle at least partially receivable within said quill motor;
- said toggle mechanism jointedly connecting said electro-mechanical driving unit with said movable mold carrier and said supporting element, and freely movably holding said electro-mechanical driving unit.
