Abstract

The installation comprises a liquid container and an electrode holder located above said container and mounted with a provision for moving the electrode to the preset position relative to the casting. The container shell is made of two telescopically jointed parts with a pneumatic seal on the joint. Secured rigidly at the level of the upper face of the lower part of the shell is a casting support. A special mechanism delivers the casting onto the support and removes it therefrom. The casting is placed on the support with the upper part of the shell lowered which allows the positioning of the electrodes above the casting to be controlled visually. Then the movable part of the shell is raised, filled with water so as to cover the casting completely, and the cores are knocked out.

Claims4

Dependent claims

An installation for electrohydraulic knockout of casting cores comprising:

a liquid in the form of a container shell consisting of a movable upper part and a fixed lower part, both parts being jointed telescopically with each other so that in the extended position the space of the upper part supplements that of the lower part and communicates with it;
a pneumatic seal located on the joint between said parts of said shell;
a casting support located practically level with the upper face of said lower part of the container shell and fixed rigidly in position;
a mechanism for delivering the casting on, and removing it from, said support;
at least one electrode holder mounted above said container shell with a provision for moving the electrode to a preset position relative to the casting core;
and a hydraulic cylinder for moving vertically the upper part of said liquid container shell.
