Method for sequential programming of an injection molding cycle of an injection molding machine
View Patent ↗In a method for sequentially programming an injection molding cycle of an injection molding machine comprising one or several injection molds, the injection molding cycle is started manually step by step. The parts of the injection molding machine and/or the parts of the injection mold(s) are manually displaced into the positions or states required for the injection molding cycle in the order required for the injection molding cycle. The movement sequence (the actions and the obtained states) of the machine parts and/or the mold parts is stored in a controller.
1. A method for programming a process sequence of an injection molding cycle of an injection molding machine having one or more injection molds, comprising the steps of
placing the injection molding machine in a set-up mode,
executing a setup cycle manually by moving the machine parts of the injection molding machine or the mold parts of the injection mold(s) sequentially with reduced speed or reduced force, or both, into respective positions required for the injection molding cycle to be performed subsequently,
recording actions or states, or both, of the machine parts or the mold parts obtained in the setup cycle,
modifying the recorded actions or states, or both, to optimize the process sequence,
storing the recorded or modified actions or states, or both, in a memory of a controller, and
operating the injection molding machine in the injection molding cycle with the process sequence using the stored or modified actions or states, or both.
2. The method of claim 1 , wherein the injection molding cycle is manually executed in the set-up mode of the injection molding machine.
3. The method of claim 1 , wherein only one or more portions of the injection molding cycle are manually executed in the set-up mode of the injection molding machine.
4. The method of claim 3 , wherein the one or more portions include movement of an ejector or of core pullers of the injection mold, or a combination thereof.
5. The method of claim 1 , further comprising the steps of providing peripheral devices, manually executing movement of the peripheral devices, and storing actions or states, or both, of the peripheral devices in the memory of the controller.
6. The method of claim 1 , wherein the process sequence is optimized by automatically executing the setup cycle by recording and modifying the actions or states, or both, at least twice before storing the recorded or modified actions or states, or both, and operating the injection molding machine.
