Abstract
PURPOSE: A metal die for forming of sand mold which is so constituted that erected protrusive cores and the core of a table center are formed to one piece and that they are split at the time of rapping for the protrusive cores, and which does not cause hindrances such as drop and enables the sand mold of high dimensional accuracy to be obtained.
CONSTITUTION: At the time of rapping of the consolidated sand in scissorlike split molds 18, 20, a simultaneous pushing-up part 24 is driven by moving an upper movable table 32 upward; at the same time, the leg parts 18', 20' of the molds 18, 20 are passed between rollers 30, 30. Thence, the leg parts 18', 20' are closed by abutting their outer sloped parts on the rollers 30, 30 so that they are guided by these rollers. At the same time, the molds 18, 20 are opened with a pivotal pin 26 as a boundary, and the cores A are rapped without any hindrance. The table center core B supported by upright lifting rods is lifted together with the cores A and is rapped, thence it is safely moved to other place.
