Problems solved by technology

[0008] The fundamental problem with all freely programmable control programs (SPS) and the above-mentioned freely programmable process control programs is that first the entire injection molding cycle is entered into the control program and then the injection molding cycle is executed as a whole, The cycle or individual cycle fragments cannot be tested without risk
But in many cases errors can lead to fatal tool corruption

Embodiment Construction

[0020] exist figure 1 The hydraulically driven injection molding machine shown schematically in , which is known per se, comprises a closing unit 1 and an injection unit 2 , which are carried by a frame 3 . The closing unit 1 comprises a fixed profiled fastening plate 4, a movable profiled fastening plate 5, a support plate 6, a crank mechanism 7 and a hydraulic cylinder 8 (closing cylinder) for operating the crank mechanism, wherein the profiled fastening plate 4 Having a fixed profiled half 9a, the profiled fastening plate 5 has a movable profiled half 9b. With this hydraulic cylinder 8 the movable profiled fastening plate 5 can be moved and the necessary closing pressure applied. It is also possible to move the movable profiled fastening plate on the one hand and to provide a separate hydraulic cylinder on the other hand for generating the required closing pressure. Furthermore, a hydraulic cylinder 10 is provided for operating the ejector and one or more hydraulic cylin...

Abstract

Disclosed is a method for programming the progress of an injection molding cycle of an injection molding machine. The injection molding cycle includes several sequences which are manually started as a whole or in part in a setup mode and in a teaching mode. In the setup mode, parts of the injection molding machine are first actuated and are tested as to the functionality thereof. The tested parts are then actuated once again in the teaching mode according to the desired sequence of movements, said sequence of movements being stored in a controller of the injection molding machine. Specific actions such as building up and reducing forces and generating holding pressure can also be taught. The individually taught sequences can then be freely combined into new processes in a controller having a suitable operator interface and can be repeated multiple times.

Description

technical field [0001] The invention relates to a method for sequence programming of an injection molding cycle of an injection molding machine according to the preamble of claim 1 . Background technique [0002] It is known from the prior art to control the injection molding cycles of the injection molding machine either on the injection molding machine itself (online) or triggered by the injection molding machine on a separate terminal (offline) by means of a freely programmable control program (SPS), ie Program the operation of the injection molding machine. In the case of online programming, the injection molding machine cannot be used for production during a longer period of time. In the case of offline programming, however, usually only brief standstills of the injection molding machine can be recorded for subsequent fine-tuning during programming. [0003] These freely programmable control programs are generally data processing programs for setting up and operating ...
