A cassette type mold apparatus includes a sub-runner formed on a parting surface of a fixed side matrix or a movable side matrix, a gate provided in a fixed side cassette mold or a movable side cassette mold and configured to inject a molten resin into a cavity space from the sub-runner, and a hot runner provided on the fixed side matrix so that a tip end thereof is aligned with the sub-runner to be perpendicular to the sub-runner and is in parallel with a mold opening and closing direction. In the cassette type mold apparatus, the movable side cassette mold can be stacked on the fixed side cassette mold in a state in which a cavity and a core are aligned and can be integrally loaded in a direction of a side surface of the entire mold.

Cassette type mold apparatus

The cassette mold type injection molding machine controls a first temperature control circuit to supply a heat medium having a heating temperature from a first heating device to a matrix supply path, controls a second temperature control circuit to supply the heat medium having a cooling temperature from a second heating device to the core cavity supply path, and performs cassette mold cool down control in which a bypass control valve is controlled to connect a bypass path and a main body supply path, such that a second heating device or a core cavity supply path is connected to a main body supply path, and thus the heat medium having the heating temperature is supplied to the matrix and the heat medium having the cooling temperature is supplied to a cassette mold main body and a core cavity portion.
