The present invention offers a technique for providing assistance in setting up control for releasing gas from the interior of a mold device to the outside of the mold device. A display device for an injection molding machine display a screen. The screen includes a tab display field, in which a plurality of tabs are arranged, and a selection screen display field, in which selection screens that are selected for the respective plurality of tabs are displayed. The tab display field includes a first tab. The first selection screen, displayed in the selection screen display field when the first tab is selected, includes a plurality of input columns for use in a control of the release of gas from the inside of the mold device to the outside of the mold device.

A method for determining optimized shape data representing a shape of a molded workpiece formed from a molded material or/and a mold cavity of a molding tool, wherein the molded material hardens depending on at least one solidification parameter, the method including: a) providing shape data representing a shape of the workpiece or/and cavity, b) providing material data representing the molded material, c) providing molding process data representing the molding process, d) providing tool data representing the tool embodying the cavity, e) determining predictive shape data based on initial model data comprising the at least one solidification parameter and data provided in steps a), b), c), and d) simulating the molding process, f) generating optimized predictive shape data as the optimized shape data based on at least predictive shape data determined in step e) and based on first initial AI data comprising the at least one solidification parameter and data provided in steps a, b), c), and d), by means of an artificial neural simulation optimization network trained to optimize predictive shape data.

A mold test apparatus includes a mold support plate having a top surface on which a mold is mounted, wherein the mold support plate includes a plurality of test suction pipes communicating with paths in the mold, vacuum pipes each having one end connected to one of the plurality of test suction pipes, a pump connected to the other end of the pipe, and at least one pressure sensor configured to measure a pressure of the vacuum pipe, wherein the paths communicate with adsorption holes provided in a top surface of the mold, and wherein the at least one pressure sensor includes a determining unit configured to determine whether the adsorption holes are clogged by using the measured pressure.
