  • Patent number: 10441996
    Abstract: 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.

  • Patent number: 10226855
    Abstract: A clamping unit (1) for clamping a workpiece, with an electric drive, and a gearbox unit having an arrangement of rolling elements (9). The gearbox unit is used to convert a rotary motion of an actuating element into a translational motion. By means of translational motions of the actuating element, clamping elements (5) can be moved into a clamping position in which a workpiece is clamped with clamping elements (5), and into a release position in which clamping elements (5) release the workpiece.

  • Patent number: 8302660
    Abstract: A feed block unit for a hot-runner feed system of a pressure die-casting machine includes a block body in which is incorporated at least one melt-conveying channel running out of the block body by way of a sprue orifice close to the gate, and a heating system, integrated into the block body, for the at least one melt-conveying channel. The feed block unit is designed as a structural unit which is insertable independently into a respective casting mold, and/or the heating system integrated therein includes at least a first heating device for supply channel heating and a second heating device, which can be controlled independently of the first heating device, for sprue channel heating. With this modular hot-runner feed system, individual temperature profiles can be predetermined and set for the respective feed block unit.
