【Abstract】 On the basis of injection parts,the author puts forward a new type of cooling model for injection-molded slabs with slats,after being simplified,makes theoretical derivation and gives the temperature distributions in the solid and liquid phases,the formula of the solid-liquid layer site and the required cooling time when the temperature of core layer of the slab with slat is reduced to T m.The author discusses the best scope of cooling time of slabs parts with slats.更多还原
