Title: Removing method of consumable pattern in investment casting
Inventor: HAYASHI YOSHIROU
IPC: B22C9/04
Filed: 1984-01-24
Abstract: PURPOSE:To prevent cracking of a casting mold and to reduce the cost thereof by irradiating microwaves to a consumable pattern while a specific pressure is applied thereto and removing the pattern from a mold. CONSTITUTION:A consumable pattern constituted of a sprue 1, a runner 2, a gate 3 and a product part 4 is manufactured of wax, etc. After such pattern is coated with a refractory material, microwaves are irradiated thereto under 2- 3.5 atmospheric pressure and the pattern is removed from the mold. Thermal expansion of the consumable pattern is suppressed by the pressure exerted thereto and therefore the cracking of the casting mold is prevented. The thermal efficiency of the device is improved and the space for installation is decreased. A considerable reduction in cost is attained from reusability of the material, etc.
