Abstract
A shaping machine includes a stationary first mold mounting plate, a second mold mounting plate movable with respect to the first mold mounting plate, a tubular snorkel fixedly secured to the second mold mounting plate, and an injection unit for plasticizing and injecting a molding material. An abutment is designed so that, in the opened condition of the closing unit, the injection unit can be braced against the abutment, and so that, in a closed condition of the closing unit, the injection unit is freed from the abutment by the force action of the snorkel on the injection unit.
Claims23
A shaping machine comprising:
- a closing unit which includes
- a stationary first mold mounting plate,
- a second mold mounting plate movable with respect to the first mold mounting plate, and
- at least one tubular snorkel, wherein the at least one snorkel is fixedly secured to the second mold mounting plate;
- and
- an injection unit for plasticizing and injecting a molding material,
- wherein there is provided at least one abutment, the at least one abutment being configured such that in an opened condition of the closing unit the injection unit can be braced against the at least one abutment, and that in a closed condition of the closing unit the injection unit is freed from the at least one abutment by a force action of the at least one snorkel on the injection unit.
A method of operating a shaping machine, the shaping machine having
- a closing unit which includes a stationary first mold mounting plate, a second mold mounting plate movable with respect to the first mold mounting plate, and at least one tubular snorkel fixedly secured to the second mold mounting plate,
- an injection unit for plasticizing and injecting a molded material, and
- at least one abutment,
- the method comprising:
- bracing the injection unit against the at least one abutment in an opened condition of the closing unit;
- closing the closing unit by displacement of the second mold mounting plate in a direction of the first mold mounting plate;
- and
- upon closure of the closing unit lifting the injection unit off the at least one abutment by a force action of the at least one tubular snorkel on the injection unit.
