Diode plastic package control device

The utility model provides a diode plastic package control device. The control device can begin to calculate the injection time after a mold is closed, and automatically demolds when the time demanded by the stipulated process is achieved, so that artificial abnormal phenomenon is completely eradicated. The control device disclosed by the utility model is arranged on a diode plastic package press; the diode plastic package press comprises an upper press mold and a lower press mold for plastic package molding, and a manual die sinking key; optical coupling sensors for sensing opening and closing of the upper mold and the lower mold are arranged at the sides of the upper press mold and the lower press mold; the optical coupling sensors are connected to a timer for calculating the plastic package process time; the timer is connected to a controller for controlling the upper press mold and the lower press mold to automatically open and close; the controller is connected to a press die sinking controller of an ori
