摘要： The invention relates to a hydraulic device for supplying a plurality of work units (3a, 3b), in particular on a plastics injection moulding machine, said device comprising at least one controller (7), at least one valve regulator and/or one valve controller and a central drive (1). A regulating valve (13a, 13b) with a regulating-valve geometry is provided on at least one of the work units (3a, 3b). Pressure sensors (8) detect at least one pressure both upstream and downstream of the regulating valve (13a, 13b), the load pressure (10a, 10b) of at least one of the work units (3a, 3b), and the system pressure (9). Since the valve regulator and/or the valve controller has knowledge about the regulating-valve geometry of the at least one regulating valve (13a, 13b) and is designed to derive, from a relationship between the regulating-valve geometry and at least one pressure difference resulting from the pressures detected upstream and downstream of the regulating valve (13a, 13b), at least one volume flow rate actual value per regulating valve (13a, 13b), and the controller (7) is designed to derive, from the volume flow rate setpoint values of the at least one work unit (3a, 3b) and/or the volume flow rate actual values of the at least one regulating valve (13a, 13b), at least one setpoint value feedforward control for the central drive (1) in such a way that the system pressure (9) corresponds at least to the relevant highest load pressure (10a, 10b) of the work units (3a, 3b), the hydraulic device is improved in terms of functionality, energy, efficiency and economy.

摘要： The invention relates to a device and method for detecting a force on an injection moulding machine for processing plastic materials. According to said invention, a first element (100) interacting with a mechanical drive and movable at least indirectly thereby in a direction of movement (x) is displaced during said displacement with respect to a second element (200) positioned near the first element (100) or oppositely thereto. A force measuring device (D) is used for determining the force applied on the first (100) and/or second (200) element by the actuation of the injection moulding machine produced by the relative displacement thereof between the first (100) and second (200) elements. A hydraulic chamber whose size is modifiable during the relative displacement associated with a change in pressure of a fluid medium in said hydraulic chamber is firmed between the first (100) and second (200) elements, wherein said change in pressure forms an input signal for adjusting the force or pressure and a pressure-relief valve (30) is used for bypassing the hydraulic medium to a hydraulic medium container (35), when the predetermined or predeterminable presser is exceeded in the hydraulic chamber (10), thereby making it possible to obtain a device and method for detecting a force on an injection moulding machine which makes it possible to determine said force in a favourable alternative manner and simultaneously ensure an overload protection.

摘要： A system for controlling nozzle touch force, which is capable of maintaining the touch force relying upon a simple constitution. An electric motor moves the injection unit forward via a spring to bring a nozzle into contact with a metal mold. Further, the spring is compressed to impart a preset nozzle touch force. In the injection/pressure-maintaining step, the screw is driven, and a position/speed detector provided on a servo motor for injecting the resin detects the injection speed at regular intervals. A force produced by the force of inertia of the moving portions such as the injection screw and the pusher plate that move due to the injection operation, is found from the acceleration that is found from the injection speed. The amount of compression of the spring is controlled by varying the rotational position of the motor by an amount corresponding to the force that is found to maintain the nozzle touch force constant. Since the nozzle touch force is maintained constant, no resin leaks and an excess of nozzle touch force is not produced, either.

摘要： The present invention relates to a method of detecting a malfunction during a die clamping step in an injection molding machine. A reference pattern is taken which shows a relation between a die clamping force and a position of a movable platen when die clamping is normally carried out. One or more monitoring sections are set in advance with respect to that position on the basis of the reference pattern and an allowable limit value of a die clamping force in the respective monitoring sections is also set in advance in a form of a linear function of the position. The die clamping force is monitored in the respective monitoring section during a respective die clamping step and, when its value exceeds the allowable limit value, it is decided that a malfunction occurs and an alarm is issued.
