DEAD-HEAD INJECTING STRUCTURE FOR CENTRIFUGAL CASTING AND DEAD-HEAD INJECTING ASSEMBLY CAPABLE OF SMOOTHLY INJECTING BY MINIMIZING SCATTERING IN INJECTING A DEAD HEAD

摘要

PURPOSE: A dead-head injecting structure for centrifugal casting and a dead-head injecting assembly are provided to perform smooth injecting of a dead head by minimizing scattering of the dead head when the dead head is further injected to fill a damaged part caused in the upper layer of casting by centrifugal force.;CONSTITUTION: A dead-head injecting structure for centrifugal casting comprises a body, a base(183), and a runner(184). The body comprises a funnel-form hollow unit. The body comprises an inner layer unit and an outer layer unit. The body comprises a funnel-form outer unit. A balance weight(185) is formed on the outer part of the outer unit. The inner layer unit forms a hollow unit. The outer layer unit protects the inner layer unit and forms the frame of the body. The inner layer unit and the runner are formed from a fire-resistant member. The fire-resistant member is fire-resistant castable.;COPYRIGHT KIPO 2012
