    摘要： An injection molding machine is provided, including a nozzle assembly (54) having a channel for conveying a fluid. At least one cavity insert (102, 200, 402) is removably mounted within a cavity plate (48, 148), the at least one cavity insert (102, 200, 402) defining a mold cavity (92, 192, 292), and a first portion of a gate (174) for communicating the fluid between the nozzle assembly (54) and the mold cavity (92, 192, 292). A gate insert (188) defines a receptacle for the nozzle assembly (54), and further defining a second portion of the gate (174). The gate insert (188) is floatably retained between the nozzle assembly (54) and the at least one cavity insert (102, 200, 402). Preferably, the gate insert (188) is retained by a gate insert plate (146) that is disposed between the cavity plate (48, 148) and the nozzle assembly (54).
