Abstract:
A controller for use with an injection molding machine having a ram to inject plastic material into a mold cavity during at least one injection molding cycle, the injection molding machine accepting a ram control variable signal to control the ram and providing at least one process variable signal indicating the operation of the ram, the controller comprising:(a) input circuitry receiving the process variable signal;(b) output circuitry providing a ram control variable signal to the injection molding machine;(c) an electronic memory storing a user defined control profile;(d) an electronic computer receiving the control profile from the electronic memory, the process variable signal from the input circuitry and executing a stored program to:(i) monitor the process variable signal during operation of the injection molding machine to model the operation of the injection molding machine; and(ii) evaluating the control profile against the modeled machine to generate an indication to the user as to whether the control profile is physically achievable with the injection molding machine.
