    摘要： Provided is a small sized injection molding machine by which a molded product can be produced with a desired level of precision with simple control. An inj ection molding machine is provided with: a longitudinal injection cylinder (61) to which stick-shaped molding materials (S) are sequentially supplied in line from the upper side, the lower end of which is formed into a nozzle shape, and the lower side of which is constituted by a material having a good heat retaining property; a heater (65) which heats the lower portion of the injection cylinder (61); and a pressing shaft (75) which presses the stick-shaped molding materials downward. When the stick shaped-molding material located at the uppermost side is pressed by the pressing shaft (75), the molding material located at the lowermost side which has already been completely melted, is injected into a cavity (21), and the heat from the heater (65) is transmitted to the die (9) side through a nozzle touch portion.

    摘要： An injection-moulding machine comprising a hot runner, arranged in a manifold, for feeding a melt into a mould, a shut-off needle for optionally closing or opening the hot runner, a piston connected to the needle, is arranged in a housing with an opening and to which a fluid can be applied from both sides, and a covering plate having two fluid feeds, into the opening wherein the covering plate, the hot runner manifold and the housing are arranged in such a way that, at a first temperature of the manifold, a distance remains between the housing and the covering plate and, at a second higher temperature the thermal expansion of the manifold and/or housing causes the housing to come into contact with the covering plate, closing the opening. In a further embodiment, a flexible seal is provided between the housing and the covering plate.

    摘要： Closure assembly (10), of the type with a multi-rod drive, for the injection moulding of plastic material (MP), comprising: a plurality of closing rods (12-1, 12-2) each associated with a respective nozzle or injection unit (11-1, 11-2) for the injection of the plastic material (MP) into a mould (20), and a driving plate (13), common to the plurality of closing rods, wherein the driving plate (13) is adapted to move between an open position (P1) and a closed position (P2), between a bottom plate (14) and the mould (20), to contemporarily drive the plurality of closing rods (12-1, 12-2) between a corresponding open (Ρ1') and closed (Ρ2') position respectively to open and to close an injection hole (18) of the injection unit (11-1, 11-2), and wherein there are provided disconnecting and fixing means (40, 41 ) associated with each closing rod (12-2, 12-2) for disconnecting it from the driving plate (13), independently from the other closing rods, and to firmly fix it, once disconnected, on a side (20a) of the mould (20). Advantageously, the closure assembly allows an easy disconnection of a closing rod (12-1 ), for instance because defective or following a failure of it, from the driving plate (13), and at the same time allows that the other closing rods (12-2), that remain connected to the driving plate (13), can continue to be used to inject, through the respective injection unit (11-2), the plastic material (MP) into the mould (20).

    摘要： The invention relates to an injection tool for producing components by injection moulding, having a plurality of cavities (5) for forming a product in each case, having an injection nozzle (6) for injecting plastics materials for each cavity (5), wherein an injection nozzle (6) has an injection channel which can be closed by a nozzle needle (14), in order to control the injection operation, and wherein an actuating device is provided, this being designed to move the nozzle needle (14) axially between a first end position and a second end position, wherein an adjustable stop (18), which defines the first end position, is provided. Specific control of the material flow can be achieved in that the adjustable stop (18) is designed as a screw, which is formed coaxially in relation to the nozzle needle (14) and can be adjusted by an electric motor (13). The invention further relates to a method for operating such an injection tool.

    摘要： An injection molding system is disclosed that utilizes a melt channel wherein at least a portion of the melt channel has a noncircular cross-section for balancing shear in a melt stream of moldable material that flows therethrough. The noncircular cross-section of the melt channel portion may be, for e.g., capsule-shaped, extended egg-shaped, oval, teardrop-shaped, or peanut-shaped. A flow splitter is also disclosed that is positioned offset from a central axis of an upstream melt channel to protrude between inlets of respective downstream melt channels, where the upstream melt channel splits into the downstream melt channels, to thereby create a narrower inlet into one of the downstream melt channels and a wider inlet into the other of the downstream melt channels.
