Abstract
The invention relates to a casting tool for producing workpieces from light metal alloys. The system includes a positioning element, a core part, a first mold part structured to carry the positioning element and be movable toward the core part, and a core part support structured to support the core part. The system also includes at least one stop structured to limit movement of the front mold part toward the core part and to allow the positioning element to be introduced into the core part, whereby the positioning element holds the core part in a predetermined position for casting.
Claims27
A casting tool for producing workpieces from light metal alloys comprising:
- a core part;
- a first mold part structured to carry the positioning element and be movable toward the core part;
- a positioning element fixed to the first mold part and having a conical tip portion;
- a core part support structured to support the core part in preparation of casting and structured to be removable after the preparation of casting;
- and
- at least one stop structured to limit movement of the first mold part toward the core part and to allow, in the preparation of casting, the conical tip portion of the positioning element to pierce the core part that is supported by the core part support, whereby, after removal of the core part support, the positioning element holds the core part via friction in a predetermined position for casting after the preparation of casting,
- wherein the positioning element is removable from a produced workpiece when the produced workpiece casting is completed.
A casting tool for producing workpieces from light metal alloys, comprising:
- a core part support structured and arranged to support a core part;
- a first mold part and a second mold part, which define a casting mold therebetween;
- the first mold part being structured and arranged to move towards the second mold part;
- the second mold part being fixedly arranged;
- the first mold part comprising a positioning element fixed thereto;
- the first mold part being structured and arranged to move towards the core part;
- and
- a conical tip portion of the positioning element being structured and arranged to pierce the supported core part as far as allowed by a stop arranged to limit movement of the first mold part, whereby the positioning element frictionally engages the core part,
- wherein the workpiece is castable in the casting tool while the core part is held by the positioning element in a predetermined position, and
- wherein the positioning element is removable from the workpiece after casting.

- a core part support for supporting a core part;
- a first mold part and a second mold part, which define a casting mold therebetween;
- the first mold part being structured and arranged to move towards the second mold part;
- the second mold part being fixedly arranged;
- the first mold part comprising a positioning element;
- the first mold part being structured and arranged to move towards the core part;
- and
- the positioning element being structured and arranged to frictionally engage the core part and comprising:
- a conical tip portion structured and arranged to pierce the supported core part;
- and
- a stop arranged to limit movement of the first mold part;
- wherein the workpiece is castable in the casting tool while the core part is held by the positioning element in a predetermined position, and
- wherein the positioning element is removable from the workpiece after casting.
