Abstract

PURPOSE: To make the size of the hopper smaller, by feeding the molding material consumed within the predetermined number of cycles to the hopper by operating the feeding device according to the output signal of the molder timer in time of accomplishing the predetermined molding cycle.
CONSTITUTION: When the switch 11 is made for the automatic operation and time of the injection amount setting timer 12 is up after elapse of operating time, the feeding amount setting timer 10 is operated by sending the signal, dry air is fed to the ejector 5 by opening the solenoid valve 6, the molding material in the container 7 is fed to the hopper 1 via the transporting pipes 8, 9 dry air is exhausted from the inner cylinder 3 of the hopper 1. After time-up of the timer 10 by elapse of operating time, the valve 6 is closed and dry air feeding to the ejector 5 is stopped and molding material feeding to the hopper 1 is stopped. The molding material of one cycle amount of the injection molder added with some allowance is fed within the operating time of the timer 10.
