Patent number: 11141895Abstract: 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.Type: GrantFiled: March 5, 2019Date of Patent: October 12, 2021Assignee: ENGEL AUSTRIA GMBHInventor: Stephan Eppich

Patent number: 11141894Abstract: An injection unit for a shaping machine includes an injection element suitable for introducing a plasticized material into a mold tool by a linear movement of the injection element. The injection element is coupled in linear motion-transmitting relationship to a bearing element, and at least two linear drives are adapted to exert a force on the injection element by the bearing element. The force can be transmitted by a transmission element from the at least two linear drives to the bearing element and thus to the injection element, and at least one clearance is arranged between the bearing element and the transmission element such that deformations of the bearing element are not transmitted to the transmission element or are transmitted to a reduced degree.Type: GrantFiled: January 12, 2021Date of Patent: October 12, 2021Assignee: ENGEL AUSTRIA GMBHInventors: Franz Dirneder, Stephan Eppich, Robert Strasser, Gerhard Hackl-Lehner, Christoph Balka, Friedrich Pernkopf, Gernot Boehm
