An apparatus for producing a foam-molded product, including a plasticizing cylinder which has a plasticization zone for plasticizing and melting a thermoplastic resin into a molten resin and a starvation zone for allowing the molten resin to be in a starved state and which is formed with an introducing port for introducing a physical foaming agent into the starvation zone; and a physical foaming agent supply mechanism which supplies the physical foaming agent to the plasticizing cylinder via the introducing port, wherein the introducing port is open at all times, and the physical foaming agent having a fixed pressure is continuously introduced into the starvation zone from the physical foaming agent supply mechanism via the introducing port during the producing of the foam-molded product.

An injection device is provided with high convenience by the degrees of freedom in layout of a storage unit and peripheral equipment increasing by way of providing a supply unit with changeable supply direction of molding material. An injection device includes: a hopper that stores a molding material; an injection cylinder unit that heats the molding material to melt, and then injects the molding material thus melted; and a supply unit having formed inside thereof a supply hole for supplying the molding material stored in the hopper to the injection cylinder unit, in which the supply unit is fixed so that a position and orientation of an opening of the supply hole on a side of the hopper is changeable relative to the injection cylinder unit.

In order to be able to operate a dust separator with or without a lower closure element (44), the closure element (44) is part of a separate closure unit (40) which is mounted under the dust separator if required. For this purpose, the dust separator, the closure unit (40) and optionally further components, such as a delivery flow generator, are kept available in a kit so as to be able to assemble the treatment unit as required. The dust separator can be operated in batches by means of the closure element (44).
