A diecasting tool system has a machine-related base plate, at least one set of contour-imparting mould components which in an assembled position on the base plate form a casting contour for an associated cast part to be cast, and a plurality of not contour-imparting tool receptacle module components. The base plate, the tool receptacle module components and the contour-imparting mould components are configured for releasably assembling the associated set of contour-imparting mould components and an assigned set of the tool receptacle module components on a fastening side of the base plate for casting the respective cast part. The base plate on the fastening side has a fastening grid of a plurality of fastening points which are disposed so as to be distributed in a regular or irregular pattern across a fastening region. The set of contour-imparting mould components conjointly with the assigned set of the tool receptacle module components is able to be assembled on the base plate in at least two different orientations, and/or a plurality of sets of contour-imparting mould components with a respectively assigned set of the tool receptacle module components are present for selective assembling on the base plate.

Diecasting tool system

A hot runner feed system is provided for a diecasting mold, wherein the feed system has a melt manifold and feed block construction having an entry-side feed inflow opening, at least one first and one second exit-side feed outflow opening which open into a mold separation plane between a fixed mold half and a movable mold half of the diecasting mold, and a casting runner-duct structure that extends so as to branch out from the feed inflow opening to the feed outflow openings. The melt manifold and feed block construction at least in an exit-side block region that includes the two feed outflow openings in a transverse direction parallel with the mold separation plane in relation to a predefined nominal operating extent is made so as to be shortened by an expansion dimension which has been predefined as a thermal transverse expansion of this block region when heated from a room temperature range to a predefined operating temperature range that is elevated in relation to said room temperature range.

A collapsible core is provided for attachment to a mold half of a casting mold, particularly a diecasting mold. The collapsible core can take the form of a removable collapsible core which can be detachably mounted on the mold half on the mold cavity side. A collapsible core can have a core cylinder body of at least two first core sections in the form of cylinder segments and at least two second core sections in the form of cylinder segments arranged alternating with the first sections over the circumferential direction. The first and the second core sections are retained moveably relative to one another. The relative movement here between the first and the second core sections consists of an axial relative movement component between the first and the second core sections and a radial collapsing movement of the first and/or the second core section.

Collapsible core and a casting mold half equipped therewith

A casting plunger for a casting unit of a casting machine, includes a casting-plunger shut-off valve integrated into the casting plunger, having a valve seat and a valve body interacting therewith, wherein the shut-off valve, in an open position, enables a flow of a melt material through the casting plunger during a melt suction operation and, in a closed position, blocks said flow during a mold-filling operation. The casting plunger has a plunger sleeve, which is placeable against an inner wall of a casting cylinder of the casting unit and contains the valve seat, and a plunger ram which contains the valve body. The plunger sleeve and the plunger ram are movable axially with respect to one another by a predefinable valve stroke.
