PURPOSE:To obtain a material charging device with ease of a filler loading/ unloading operation by reducing a full length of a filler and a total weight, a longer life of a packing of a sliding part, saving of energy for an air cylinder, ideal charging of a material, and space efficiency inward of a mold clamping face. CONSTITUTION:An inner sleeve 12 having a material feed path inside is moved back and forth by a prescribed amount. When the inner sleeve is positioned on a forward position, a sealing part 12a of the inner sleeve per se seals an opening 11a of a top of an outer sleeve 11. When the inner sleeve is positioned on a retracted position, a material supplied from the rear end of the inner sleeve is charged into a mold cavity of a mold through an opening 12b of a top of the inner sleeve and the opening of the top of the outer sleeve by a charging air blown into a gap 13 formed between the outer sleeve and the inner sleeve. |
