PURPOSE:To simplify an apparatus by working a lever having a curve surface to a core pull-out and product ejection apparatuses of a die casting metallic mold, to shift the core or the product by strong force only at initial stage and by weak force at the other state. CONSTITUTION:The lever 5 having the curved surface is fitted at the end of a core-puller shaft for the core pull-out and a product ejection rod 6. And, when the shaft or the rod 6 works, the lever is energized by action of a foot 4 and shafts 9, 9 and shifted in the box 3, to pull-out the core 2 or eject the product by a pushing plate 2. Then, by the lever 5 movement, at first the force to the core-puller shaft or the product ejection rod 6 is energized to strong force and following to pull out the core and eject the product, this is changed to weak force and at last the core and the product are shifted by the original 6 force.
