    • An apparatus and method for making hollow shell cores wherein a core box assembly is provided including a vented pattern. Baffles are provided in the core box in the space between the pattern and the core box walls whereby a catalyst gas flowing into the core box through an entry port will be caused to enter the pattern and to flow along the outer layer of a sand and binder change in the pattern. The gas will then be caused to flow out of the pattern into a trapped gas vent and out of an outlet port of the core box. The continuous flow of catalyst gas through only the outside layer of the sand and binder charge in the pattern will only cause the outer layer of the charge to be cured and to form a hardened shell. After formation of the shell, the uncured sand and binder mixture in the shell will be discharged and reused. The shell is then transferred from the core box assembly.
    • 一种用于制造中空壳芯的装置和方法,其中提供包括排气图案的芯盒组件。 挡板在图案和芯盒壁之间的空间中设置在芯盒中,由此通过入口流入芯盒的催化剂气体将被引入图案并沿着砂和粘合剂的外层流动 改变模式。 然后将气体从图案流出到陷入的气体排出口并离开芯盒的出口。 催化剂气体仅通过砂的外层和粘合剂的图案中的连续流动的连续流动将仅导致电荷的外层被固化并形成硬化壳。 壳体形成后,壳体中未固化的砂和粘合剂混合物将被排出并重新使用。 然后将壳从芯盒组件传送。
