Method of manufacturing cast metal products, and manufacturing plant

Abstract

Provided are a method of manufacturing cast metal products and a manufacturing plant that use self-hardening molds and allow, using a shared production line in a single factory, either full-mold casting or wooden-mold casting to be selected and performed depending on factors such as the type of product. This allows more efficient production of cast metal products. A combined multipurpose mold manufacturing line (1) is set up in a central area of the factory, said line being shared between full-mold casting and wooden-mold casting. A full-mold casting line and a wooden-mold casting line that include the mold manufacturing line (1) are set up in parallel, making it possible to switch between the full-mold casting line and the wooden-mold casting line on the basis of decision factors such as the shape, material, and production lots of the cast metal product to be manufactured.

Description

technical field [0001] The present invention relates to a method for manufacturing a cast product by selectively implementing a foam mold (mold) casting method and a wooden mold casting method in a factory according to the type of the cast product and a factory for carrying out the method. In addition, the wooden mold casting method described here is used relative to the foam plastic mold casting method, and is used for a wooden mold, a metal mold, or a resin mold that is used as a cavity mold (cavity mold) relative to the foam plastic mold mold. , A general term for molding methods such as shrinkage foam resin molds of resin shrinkage materials contained in mixed sand. Background technique [0002] The non-mass-production casting method by the organic no-bake casting method is roughly divided into a foam mold casting method and a wood mold casting method. Foam plastic real mold casting method is a method of casting while displacing the melt with the melt while burning the ...

AI Technical Summary

Problems solved by technology

[0011] As mentioned above, there are advantages and disadvantages in the foam mold casting method and the wood mold casting method, and although it is desirable to use the foam mold casting method and the wood mold casting method differently according to the product to make use of their respective advantages, but because the two The casting method is fundamentally different in terms of technical thinking, so it has not been considered to selectively carry out the two casting methods in the same factory in the past.
