Abstract
A mold box having a first mold plate and a second mold plate. The mold box includes a single elongate guide rail extending through a bore defined by the second mold plate. The single elongate guild rail allows the second mold plate to be movably arranged relative to the first mold plate.
Claims20
An injection molding machine comprising:
- a frame;
- a clamping unit being attached to the frame;
- and
- a linear drive mechanism,
- wherein:
- the clamping unit comprises:
- a clamping unit frame;
- a base plate fixedly arranged at a first end of the clamping unit frame;
- a second end structure fixedly arranged at a second end of the clamping unit frame;
- and
- a mold box,
- the mold box comprises:
- a first mold plate;
- said second mold plate movably arranged relative to the first mold plate along a longitudinal axis;
- and
- a main guide rail system configured for guiding the second mold plate linearly away from and towards the first mold plate when moved by the linear drive mechanism of the clamping unit,
- the main guide rail system comprises:
- only one main guide rail pillar including:
- a first end;
- a second end, the first end of the main guide rail pillar being fixedly connected to the base plate of the clamping unit, and the second end of the main guide rail pillar, being fixedly connected to the second end structure of the clamping unit;
- and
- a cross section perpendicular to the longitudinal axis, the cross-section forming a polygon.

An injection molding machine comprising:
- a frame;
- a clamping unit mounted to the frame;
- a linear drive mechanism;
- a first mold plate fixed relative to the clamping unit;
- a second mold plate arranged for linear movement relative to the first mold plate along a mold opening axis;
- and
- an elongate guide structure extending parallel to the mold opening axis and fixed at opposite ends to the clamping unit, the elongate guide structure supporting the second mold plate during movement by the linear drive mechanism and defining planar guide surfaces that inhibit rotational movement of the second mold plate about the mold opening axis.
4 more elements
An injection molding machine comprising:
- a frame;
- a clamping assembly secured to the frame;
- a base plate fixed relative to the clamping assembly;
- a first mold plate fixed relative to the base plate;
- a second mold plate movable relative to the first mold plate;
- a linear actuator configured to move the second mold plate;
- and
- a single guide pillar extending between a base-side structure and an opposing end structure of the clamping assembly,
- the second mold plate being slidably mounted on the single guide pillar by a bearing arrangement that constrains rotational movement of the second mold plate during linear travel.
