Provided is an injection molding machine that can reduce variations in the position of a slider with respect to a prescribed position. An injection molding machine of one embodiment comprise: a second injection device as an injection device for injecting a resin to a mold from a direction intersecting an extension direction in which a tie bar extends; a slider that supports the second injection device and slides same along the extension direction with respect to a fixed platen; and an adjuster that is disposed on a side of the fixed platen opposite to side where the mold is disposed, that regulates the slider so that the slider does not slide, with respect to the fixed platen, beyond the prescribed position in a mold opening direction of the mold, and that is capable of adjusting the prescribed position in the extension direction.

A multi-component injection moulding machine provided has a machine bed, two mould mounting plates movable relative to one another by a closing unit, an injection unit and an extruder unit. The injection unit moves relative to the neighbouring mould mounting plate and has a nozzle having a nozzle head. The extruder unit is adjustable between a first position, where a nozzle contact of the extruder unit rests on the nozzle head, and a second position releasing the injection unit for contacting of the nozzle head on a tool mounted on the neighbouring mould mounting plate. In the first position, the extruder unit and the injection unit can be directly coupled, and the extruder unit has a coupling unit having a second clamping element cooperating mechanically with a clamping element on the injection unit such that the coupling device provides a pressing force of the nozzle head on the nozzle contact.
