    • A die provided for fixing a porous ceramic insert for producing a light metal component which is reinforced by the insert. For this purpose, the insert is positioned in the die in such a way that any force which occurs for the purpose of fixing the insert is compensated for by a collinear force, which minimizes the bending moments exerted on the insert. Furthermore, shielding elements are used to protect the insert from a casting metal flowing into the die. Furthermore, the invention describes a process in which the velocity of a casting plunger which moves the casting metal into the die is regulated in such a way that the insert is not damaged by the kinetic energy of the casting metal. This is achieved by filling the die at a low velocity until the metal has flowed around the insert. Then, the casting plunger is accelerated, thus ensuring optimum filling of the die with the casting metal.
    • 一种用于固定多孔陶瓷插入件的模具,用于制造由插入件增强的轻金属部件。 为此,插入件以这样的方式定位在模具中,使得为了固定插入件而发生的任何力由共同的力补偿,这使施加在插入件上的弯矩最小化。 此外,屏蔽元件用于保护插入件免于流入模具的铸造金属。 此外,本发明描述了一种方法,其中将铸造金属移动到模具中的铸造柱塞的速度被调节为使得插入件不被铸造金属的动能损坏。 这是通过以低速填充模具来实现的,直到金属围绕插入件流动。 然后,铸造柱塞被加速,从而确保模具与铸造金属的最佳填充。
