An injection apparatus includes a plasticizing portion configured to plasticize a molding material, a nozzle configured to eject the molding material, and a changing mechanism capable of changing an orientation of the plasticizing portion and the nozzle.

An injection-molding system includes an extruding system configured to produce a mixture; a discharging channel communicable with the extruding system and including an outlet configured to discharge the mixture; and molding devices configured to receive the mixture. Each of the molding devices includes a hollow space, and a feeding port communicable with the hollow space and engageable with the outlet. An injection-molding method includes providing an extruding system configured to produce a mixture, a discharging channel including an outlet, and first and second molding devices; engaging the outlet with the first molding device; injecting the mixture into the first molding device; disengaging the outlet from the first molding device; moving the discharging channel away from the first molding device and toward the second molding device; engaging the outlet with the second molding device; injecting the mixture into the second molding device; and disengaging the outlet from the second molding device.

Some embodiments relate to a method for the direct soling of a multilayered shoe sole. The method can provide two distinct sets of mold frames for a first and a second shoe sole layer and a distinct order for the soling of the layers. In contrast to art traditional approaches, a first layer (e.g. a midsole) is first soled to an upper in a first mold frame and subsequently a second layer (e.g. an outer sole) is soled onto said first layer in a second mold frame. The method can allows for an increased design flexibility and the inclusion of additional functional or aesthetic features, such as air pockets, undercuts, toe caps or running sole tips previously not possible with direct soling processes. Some embodiments relate to an injection molding system equipped and configured for carrying out the method.

An injection device includes: a swivel base; and an injection unit mounted on the swivel base and configured to be rotatable, in which the injection unit is provided with a swivel mechanism including: a horizontal support shaft having a tip end portion fixed to the injection unit; an axle penetrated by the support shaft at a position eccentric from an axis and rotatably provided with respect to the support shaft; and a wheel penetrated by the axle at a position of an axis and is rotatably provided with respect to the axle, in which in a case where a rotation position is set to a stop position, the wheel is apart from the swivel base, and in which in a case where the rotation position is set to a swivel position, the wheel contacts with the swivel base and the injection unit is swivelable on the swivel base.

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.
