摘要： A clamping unit for an injection molding machine includes a fixed platen, a support platen, and a moving platen which is arranged between the fixed platen and the support platen for back and forth movement. An opening and closing mechanism constructed as crank drive having at least one crank disk is provided to effect a back and forth movement of the moving platen in relation to the support platen, with the crank disk rotatable by a drive mechanism. A first connecting rod links the crank disk to the support platen, and a second connecting rod links the crank disk to the moving platen, wherein at least one of the first and second connecting rods is articulated in eccentric relationship to the crank disk. A pulling means extends between the support platen and the fixed platen to allow a buildup of a clamping force between the fixed platen and the moving platen.

摘要： An injection molding device includes a continuously operating extruder and a discontinuously operating injection unit receiving plastic material from the extruder. The extruder has an extruder barrel which includes a plasticizing zone and a discharge zone, whereby the discharge zone is configured to provide an intermediate storage space and has a cross sectional area which is greater than a cross sectional area of the plasticizing zone. In this way, the discharge zone provides a buffer volume which is filled during the injection process and then emptied again.

摘要： An injection molding machine has a pair of C-shaped tension members interconnecting the fixed bracing plates at location above the axis of force action in the mold closing and injection operations. The mold closing unit is mounted on one of these plates and a mold part on the other plate while the mold closing unit acts on the movable mold part. According to the invention, the fixed plates are also interconnected by lower tension members which can be C-shaped or can be tension rods so that access to the space between the mold parts remains available, the upper and lower tension members being matched as to elongation under the generation of the mold closing and injection forces.

摘要： A clamping unit, particularly for an injection molding machine, includes at least one moving platen which is moveably arranged on a frame element. At least one hydrostatic support is provided in an area between the platen and the frame element for facilitating back and forth displacement of the moving platen to thereby avoid speed-dependent friction values. Operation of the clamping unit is realized by building up pressure in a hydrostatic support before the moving platen is initiated for displacement so that the moving plate is slightly raises platen in relation to the frame element. After displacement of the moving platen, the pressure in the hydrostatic support is decreased again.
摘要翻译：特别是用于注射成型机的夹持单元包括可移动地布置在框架元件上的至少一个移动压板。在压板和框架元件之间的区域中提供至少一个流体静力支撑件，以便于移动压板的前后移位，从而避免与速度相关的摩擦值。夹紧单元的操作通过在启动移动的压板以移动之前在静液压支架中建立压力来实现，使得移动板相对于框架元件稍微升高压板。在移动的压板移动之后，静液压支架中的压力再次降低。

摘要： A mold closing device of an injection molding machine for producing plastic parts made of two or more plastic components includes a central mold carrier element which is arranged between two outer mold mounting plates and has two or four opposing mold mounting areas arranged in pairs for affixing two or four mold halves and which is fitted with a turning device supported in a supporting frame. Each of the mold halves of the mold carrier element can be closed against the mold halves of the outer mold mounting plates by a drive mechanism and a mold pressure unit. The outer mold mounting plates are interconnected by columns which extend through the supporting frame for the central mold carrier element. The supporting frame is fixedly connected to the machine frame while the outer mold mounting plate is displaceably supported on the machine frame.
