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.

摘要： Devices, systems, and methods for monitoring the operation of an injection molding machine, for example, a wax injection molding machine, are disclosed. The devices, systems, and methods may be used for injection molding machines having an injection die, a molding medium injection cylinder, and a control cylinder coupled to the injection cylinder, the control cylinder having a fluid supply conduit. Monitoring and/or control are practiced by monitoring the fluid pressure and the flow rate of the fluid in the conduit. This flow rate and pressure are used to calculate the fluid pressure and flow rate of the molding medium injected into the injection die. A data acquisition system may be used to calculate and output the calculated data. The system can be portable and adaptable for use with any type of injection molding machine and for any injection molding medium.

摘要： The retreat completion position of the screw in the charging step in actual production is controlled based on the result in pilot production as follows. In pilot production, the measurement value Ts of the screw driving torque is integrated with respect to the screw position P from the forward limit to the retreat completion position Ps. When conforming item is produced in the pilot production, the value &Sgr;Ts·dP obtained as a result of the integration is stored as a reference value. After actual production begins, the measurement value Tx of the screw driving torque is integrated in real time with respect to the screw position P from the forward limit to the screw position at each time. The obtained value &Sgr;Tx·dP is monitored. When this value &Sgr;Tx·dP coincides with the reference value &Sgr;Ts·dP, it is determined that the charging step has been completed, and the retreat operation of the screw is stopped.
