Problems solved by technology

If material shrinkage within the cooled cast component occurs with respect to possible spatial directions, mechanical tension states and failure states will have the effect of affecting the integrity of the cast component
Thereby, the drawback in the prior art is that the possibility of not finding this kind of state and not taking preventive measures

Embodiment Construction

[0086] figure 1 A schematic view of an insert 1 is shown which should be fastened during the production of the component by means of metal casting or injection molding of this component. Such inserts are classified as threaded inserts, sleeve-shaped plug-in connectors, with (eg figure 1 ) or wire threaded inserts without front flanges and socket-like electrical connectors. Such an insert 1 is positioned in the mold cavity of a metal casting or injection mold, which is subsequently filled with molten metal or molten plastic. The casting mold is schematically shown at Figures 3 to 6 , 8, 10 to 12, 14 to 16, 18 to 21. In this way, for example, by means of aluminum die-casting to produce engine blocks or housings for transmissions, or by means of injection molding to produce plastic device housings. Preferably, in the metal casting process, light metals are processed, especially aluminum, magnesium and their alloys, as well as zinc, cast iron, copper, steel and their alloys. ...

Abstract

The present invention describes a metal casting method and a plastics injection molding method in which a material melt is cast around an insert in such a way that the material melt does not penetrate into the interior of the insert. The use of a wire thread insert as the insert has the advantage that threaded holes can be produced for example in a cast aluminum part already during the casting process. For this purpose, the present invention discloses the corresponding casting mold, the insert and the casting method.

Description

technical field [0001] The present invention relates to metal casting molds and injection molding molds, inserts moldable into metal castings or injection moldings, casting methods for the production of said metal castings or injection moldings, metal casting methods and injection molding methods and products produced therefrom casting. Background technique [0002] Molten metals and plastics used in cast components have extremely low viscosity in the temperature range of the molten state. Such properties lead to the fact that even the smallest gaps and cavities, for example in inserts or in casting moulds, are penetrated during the casting of these molten materials. Especially in pressure-supported casting methods, for example in aluminum die-casting or in injection molding methods for plastics. During the molding or overmolding of inserts, such as threaded inserts, by means of molten metal or by means of liquid plastic, there is the risk that said liquid material will pe...
