Provided is a management device capable of communicating with a counting device that counts the number mold opening and closing cycles. The management device includes a memory and a processor. The processor outputs one or more index values that can be used for determining a next maintenance timing, by using a first value that is a count value acquired from the counting device, and one or more second values that are count values, at a last maintenance time, stored in the memory.

A control device includes: an injection control unit that controls, in a pressure holding process of controlling a pressure acting on a molding material from an injection member, an injection drive source based on a set value of the pressure and an actual value of the pressure. The injection control unit performs pressure reduction control to gradually reduce the actual value of the pressure with respect to the set value of the pressure from a middle of a k-th stage (k is an integer of 1 or more and n or less). The control device includes a ratio setting unit that sets a time ratio Tr(k) in the k-th stage and a pressure ratio ?Pr(k) in the k-th stage based on a set value P(k) of the pressure in the k-th stage, a set value T(k) of a holding time in the k-th stage, and information stored in advance.

The manufacturing apparatus includes a nozzle, an injection cylinder, an injection plunger, a plunger pressing member, and a movable unit for moving the plunger pressing member. The movable unit has a ball screw including a moving member and a screw shaft, and the moving member is movable to a first position, a second position, and a third position along the screw shaft. A central processing unit (CPU) of a control apparatus controls the movable unit to move the moving member to the third position in a repetition of an injection operation in which the moving member is moved between the first position and the second position.

A display unit of an injection molding machine, which includes an injection member provided in a cylinder heating a molding material and an injection drive source causing the injection member to advance to fill an inside of a mold unit with the molding material, displays a screen including a selection part, which receives a selection of whether to perform a retreat speed control to control an actual speed value of the injection member to a first set value or a retreat speed limitation to limit the actual speed value of the injection member to a second set value or less during a retreat of the injection member, in an injection process for controlling a speed of the injection member or a pressure acting on the molding material from the injection member.

A control device of an injection molding machine, which includes an injection member provided in a cylinder heating a molding material and an injection drive source causing the injection member to advance to fill an inside of a mold unit with the molding material, includes an injection control unit that performs a retreat speed limitation to limit an actual speed value of the injection member to a first set value or less during retreat of the injection member in a holding pressure process for controlling a pressure acting on the molding material from the injection member. The injection control unit releases the retreat speed limitation in a case where a first set condition is satisfied while the retreat speed limitation is performed.

A higher-level substrate and lower-level substrates communicatively connected to the higher-level substrate are provided. The higher-level substrate is configured to obtain identification information from each of the lower-level substrates at first timing, to obtain identification information from each of the lower-level substrates at second timing following the first timing, and when the identification information obtained at the first timing is different from the identification information obtained at the second timing, notify a user of substrate replacement of that lower-level substrate for each lower-level substrate.

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 controller for an injection molding machine includes processing circuitry. The processing circuitry is configured to store, in a storage, information on an action taken on the injection molding machine, user information indicating a user who has taken the action, and information on time for taking the action in association with each other, with respect to each of actions taken on the injection molding machine. The processing circuitry is further configured to refer to the storage to display, on a display, the number of actions taken by the user or time required for taking the actions by the user in a visually recognizable manner using a figure, with respect to each of users indicated in the user information.

In a display control device, a first display control unit displays values of a plurality of molding conditions in a first display area, on the basis of layout information including a display size and a display position of the plurality of molding conditions. A data setting unit sets as molding data the values of the plurality of molding conditions that are displayed in the first display area. On the basis of the layout information, and in the same layout as that of the first display area, a second display control unit displays for inspection in a second display area the values of the plurality of molding conditions based on the molding data which are stored in a storage unit.
