Optionally, in the intelligent control method of the heading press, if the processing target value is of a second type, a second execution module is called, and the second execution module executes the following steps:
judging whether the opening limit is larger than the current size, if so, issuing a mold opening valve opening instruction to the execution unit; if not, no action is performed; it can be understood that the opening instruction of the mold opening valve is issued to the execution unit only when the condition is reached, and if the condition is not reached, the opening instruction of the mold opening valve is not issued, namely no action is taken.
Judging whether the target pressure value is larger than the current pressure value, if so, issuing a mold closing valve opening instruction to the execution unit; if not, the program is ended, the module completion mark is sent, the operation is skipped to the action keeping module, the condition that the opening instruction of the mold closing valve is sent to the execution unit only when the condition is met can be understood, if the condition is not met, the opening instruction of the mold closing valve is not sent, namely no action exists, and when the opening instruction of the mold closing valve is not needed to be sent, the current pressure value is shown to reach the target pressure value, so the module completion mark is sent at the moment.
Optionally, in the intelligent control method of the heading press, if the processing target value is of a third type, a third execution module is called, and the third execution module executes the following steps:
