CORE BRACE

The invention relates to a core support consisting of a compressed web with support elements attached to the front side for open water jacket cores, a mold for casting engine housings. The support elements are welded to the web.

When casting engine housings, the future cooling water space is filled with a mold core during the casting process. If the mold core is broken through between the core inserts for the cylinders in order to obtain a compact engine, core supports must be placed at these points before casting to prevent the core parts from floating during casting. These core supports must firmly brace the core parts without damaging them.

Usually, several core clamps are used in one mold - each between the perforated ones for the cylinders. Since the clamping of the individual core clamps is not uniform, due to tolerance fluctuations and bending of the core parts, individual core clamps often come loose - especially during handling.

KARL· SCHMIDT SCHMITTEN/TS

According to the invention, it is therefore proposed that the support elements be designed to be resilient. The concavely curved support plates have recesses on the left and right edges and thus form a resilient web. The support plates have a supporting function in the lower part, followed by the resilient web bent outwards with the remaining piece for guidance. By making the upper part of the support plate resilient, a reliably secure fit of each individual core clip is ensured.

The core clasp is shown schematically in Fig. 1 and Fig. 2. The concavely curved support plates (1) are notched in the upper part on the right and left edges, so that a narrow web (2) is formed, with a concavely curved remaining piece (3) attached. The web (2) and remaining piece (3) are bent outwards. Both support plates (1) are connected by a central web (4), the head ends of which have concavely formed upsets (5) whose contours correspond to those of the support plates (1). The central web (4) is flattened in the middle in a mirror-symmetrical manner (6) for reasons of space.

Claims (1)

KARU SCHMIOT SCHMITTEN/TS CLAIM Core clamp consisting of a web (4) with concavely formed upsets (5) on the front side and mirror-symmetrical flats (6) in the middle, as well as two concavely curved support plates (1) arranged on the front side, characterized in that the support plates are notched in the middle area on the left and right edges and thus produce a concavely curved lower part for support and a concavely curved, smaller, upper part for guidance, which are connected by a narrow web (2), whereby the web (2) and guide part (3) are bent outwards in order to ensure resilient bracing of the core clamp.
