Setting method for the semi-automatic production of a process-capable basic setting for an injection molding machine

Abstract

The invention relates to a setting method for the semi-automatic production of a process-capable basic setting for an injection molding machine (1) for processing molding compounds made of plastic. Using an interactive start-up assistant (15) that is integrated in a control apparatus (14) of the injection molding machine (1) by way of software, wherein said start-up assistant (15) guides an operator of the injection molding machine (1) in steps at least through partial sections of the setting process, values or variables for system-relevant process parameters are determined by which a process-capable basic setting is attained as quickly and reliably as possible. For this purpose, prior to starting a test phase, those conditions are defined on a preliminary basis which significantly influence the flow properties of the molding compound, in particular the injection speed and the compound temperature. In addition, a characteristic for the respective flow behavior is determined at least approximately by the start-up assistant (15), in particular a viscosity of the molding compound that is used under said preliminarily established process conditions. Said characteristic for the flow behavior of the molding compound, and optionally other process characteristics which have been determined or specified, are used to establish a provisional, preliminary setting for the target value and / or for the upper threshold value of the injection pressure for the test phase to be started thereafter.

Description

technical field [0001] The invention relates to a setting method for the semi-automatic establishment of a production process-usable basic setting of an injection molding machine for processing plastic injection molding materials. Background technique [0002] The claimed method is the determination and adjustment of the most important operating and process parameters of a plastic injection molding machine in a semi-automatic, reproducible and as operationally reliable manner as possible, wherein the purpose of the adjustment method is, when using a new or changed When combining tools, materials and injection molding machines, it is possible to find initial settings for the production process as quickly as possible or to achieve basic settings that are as stable as possible. [0003] As is well known, plastic injection molding is a direct, fully automated process for producing finished parts from raw materials, wherein generally no or only minimal finishing of the molded par...

However, cases and combinations of materials, tools and machines have been observed so far for which satisfactory results cannot be obtained with the aforementioned starting aids

Especially for some cases it may happen that the quality of the initial setup is not good enough or the result is good enough after an excessive number of test cycles and parameter matching
