摘要： The invention relates to a novel method and a novel device that allows the production of a center opening in a flat data carrier while safeguarding a generally optimized quality of production. According to the invention, the passage for the center opening is produced by performing a cutting movement only after termination of the injection phase or at the end of a compensation flow between the screw prechamber (72) and the mold cavity, however, before the sprue section has entirely solidified. The cutting movement reduces the sprue volume. The corresponding volume reduction flows back to the screw prechamber (72) and is included in the calculation during the dosing phase for the subsequent injection cycle. In a first injection step of a new injection an exact mold amount can be prepared in the screw prechamber (72) with the exit closed.

摘要： The invention relates to the production of preforms (10) for PET bottles in batch quantities. According to the invention, the mould nests are arranged in the injection moulds in a specific manner, thereby increasing the number of cooling positions in an after cooler (19, 40). The inventive device is provided with controllable/adjustable movement means for the two coordinates (x, y; y, z) of the transfer plane of the after cooler (19, 40), enabling the after cooler (19, 40) to be cyclically positioned with respectively free cooling positions in the fixed arrangement of moulded objects (10) in the moulds, whereby a maximum density of cooling positions can be obtained in said after cooler (19, 40) . The invention enables four times more cooling positions to be obtained, especially when arranged in a staggered manner, in comparison with the number of mould nests in said mould, in addition to allowing the number of mould nests to be increased to 144 and more.

摘要： The novel invention provides for the controlled correction of possible quantitative errors in the production of optical data supports. The cavity of the mould is only partially filled prior to the stamping phase. It is the subsequent stamping that is used to complete the filling process by moving one mould half. In the first phase of stamping or compressing the melt, the pressure is detected in defined positions of the moulds or at a defined point in time and any deviation from a predetermined set pressure value is corrected by the immediate introduction of a movement change in the stamping process. By acting on the pressure conditions in the mould cavity, it is possible to influence the backflow before the sprue is set, in terms of a set weight value of the finished data support.

摘要： The aim of the invention is to improve the cooling or subsequent cooling range during the production of pre-shaped bodies for PET bottles, so-called preforms. Water cooling is primarily used for initial cooling and also during subsequent cooling. The air action, however, is improved by assigning mechanically displaceable elements to the air side action. As a result, the security with regard to malfunctions during handling as well as the cooling action can be improved. When combined, two especially advantageous embodiments yield an optimal solution. A valve-like element is provided for ejecting and an air nozzle is provided for the interior of the preforms, said nozzle assisting in the handling and cooling.

摘要： The invention relates to a toggle linkage closure unit for an injection moulding machine, comprising a stationary platen (8), a movable platen (6), a support plate (7) and a toggle linkage (4) arranged between the support plate (7) and the movable platen (6). A cross head (5) that is in operative connection with the toggle linkage (4) is moved by means of an electric drive (10). According to the invention, in addition to the electric drive (10), at least one hydraulic drive having a piston-cylinder system (11) is provided, the piston-cylinder system being in operative connection with the cross head (5). The length (L
Z ) of the cylinder (11a) and the length (L
S ) of the piston rod (11b) are designed and aligned in relation to one another in such a way that the hydraulic drive can follow the travel path (S) of the cross head (5) during the travel of the movable platen (6) between an open position of the closure unit, in which the toggle linkage (4) is folded, and the closed position, in which the toggle linkage (4) is in a predeterminable extended position and closing force is built up.
