PROBLEM TO BE SOLVED: To use a base tube portion of a raw material filling machine for a foamed plastic as it is irrespective of a change in a mold, a raw material or the like by providing a raw material inlet at the portion connected to a cylinder and providing an air nozzle for returning the material at a main tube portion in the machine in which the base tube portion and the main tube portion are divided. SOLUTION: The multi-purpose filling machine comprises a base tube portion 1, a cylinder 2, a main tube portion 3 and a connecting coupler having a slider 4 and a case 5. The portion 1 has a straight tube 6 and a branch tube 7 branched from the tube 6. A front cover 14 of the cylinder 2 is engaged with a rear end of the tube 6. A piston 12 and a rod 9 fixed at its end with a plunger 10 are stored in the cylinder 2. When a raw material is filled, the piston 12 is advanced and retracted by an air pressure, a filling hole of a mold is opened and closed by the plunger 10 to supply the material to the mold. If the mold, the material or the like is changed, the portion 3 is drawn from the portion 1, and replaced for use.
