Guarantee casting pattern of cooling wall water pipe protective case position accuracy

The utility model provides a guarantee casting pattern of cooling wall water pipe protective case position accuracy adopts the injection water pipe protective case position below of pressing cooling wall drawing confirmation of size in wooden model of cooling wall and bottom plate, and the inlay is through machining's metal material disjunctor position sleeve. The locating hole quantity of position sleeve injection water pipe protective case magnitude determination in according to the cooling wall drawing inserts the location stick that is used for fixed protective case position in the locating hole, the appearance adopts cold setresin sand system type. The utility model discloses cooling wall foundry goods product water pipe protective case horizontal position deviation that the messenger cast out falls to minimumly, and the lengthwise position deviation makes water pipe protective case position dimensional deviation can reach the requirement of cooling wall product technology also because the size precision of metal position sleeve is high, the installation steadiness is good, and whole model is perforated, and 100 percent are qualified in the inspection. Reduce a large amount of waste products, improved the product quality precision, improve production efficiency, energy saving and consumption reduction.
