Abstract

The invention discloses a combined type casting box used for founding flat-bottom same-series castings, which comprises a bottom plate with a large flat plate structure, a plurality of common side plates I, a plurality of non-common side plates II with various models and a top plate arranged at the top ends of the side plates. The bottom plate is provided with a plurality of blocking grooves corresponding to the positions of the side plates of the casting boxes with various models; and the bottom parts of the side plates I and the side plates II are provided with blocking ribs corresponding to the blocking grooves. The combined type casting box used for founding flat-bottom same-series castings can greatly shorten the preparation time of the casting box, reduce the preparation difficulty, reduce fund investment and improve the efficiency.

Description

technical field [0001] The present invention relates to a sand box for foundry. Background technique [0002] The sand box is an indispensable tool in the casting production process. It is the outermost cavity made of sand according to the shape of the product. Various types of cores can be placed in it in combination to pour molten iron. After cooling, it becomes a casting. The blank is a necessary part after the sand is knocked out. [0003] However, all kinds of parts are big or small, long or short, wide or narrow, and they are all produced according to the requirements of customers. There will often be situations where customers order products with small batches, many varieties, and tight time requirements. However, the current situation is that the castings can only be produced after the overall sand box is made, and the sand box needs to be modeled first, and then the sand box is cast, so the cycle is longer, resulting in a tight delivery time. At the same time, bec...
