Abstract
A blow molding apparatus is provided with a mold carriage movable in a path between an extruder station and a blow-and-fill station. The mold carriage can have one or more mold assemblies. Each mold assembly has opposed first and second mold halves that together define a mold cavity. The first mold half is fixed to the mold carriage while the second mold half is independently movable relative to the first mold half within the mold carriage to open and close the mold assembly.
Claims7
A blow molding apparatus comprising
- a frame including a horizontal base;
- a mold carriage slidably mounted to the base for movement in a path between an extruder station and a blow-and-fill station;
- a mold carriage actuator operably associated with the mold carriage;
- at least one mold assembly in the mold carriage and comprising opposed first and second mold halves which together define a mold cavity, the second mold half being independently movable relative to the first mold half along said path to open and close the mold assembly, and the first mold half being fixed to the mold carriage;
- a mold actuator operably associated with the mold assembly for opening and closing the mold assembly;
- an extruder die head at the extruder station, mounted to the frame for vertical reciprocal movement relative to the base;
- a blow-and-fill head mounted to the frame above the blow-and-fill station;
- and
- a controller operably associated with the mold carriage actuator for positioning said mold assembly at the extruder station and the blow-and-fill station.
