## Abstract

An injection molding system includes: an injection molding machine; a screen setting storage unit provided in the injection molding machine and storing a setting state of the injection molding machine; an operation limiting unit provided in the injection molding machine and limiting operation of the injection molding machine; and a management unit including a storage unit that stores a list of a correct combination of screen settings and limiting operation of the injection molding machine, a confirmation unit that compares information of the screen setting storage unit and information of the storage unit to confirm a propriety of a combination of the screen settings of the injection molding machine, and a limiting operation determination unit that determines a limiting operation upon receiving a result confirmed by the confirmation unit to issue an operation limiting command to the operation limiting unit.

## Claims

### Claim 1

A method comprising:
storing, in a screen setting storage unit provided in an injection molding machine, a setting state of the injection molding machine;
storing, in a storage unit included in a management unit, a list of a correct combination of screen settings and limiting operation of the injection molding machine;
comparing, by a confirmation unit included in the management unit, information of the screen setting storage unit and information of the storage unit to confirm a propriety of a combination of the screen settings of the injection molding machine;
determining, by a limiting operation determination unit included in the management unit, a limiting operation upon receiving a result confirmed by the confirmation unit to issue an operation limiting command to an operation limiting unit provided in the injection molding machine; and
limiting operation of the injection molding machine according to the determined limiting operation using the operation limiting unit.

### Claim 2 (depends on 1)

The method according to claim 1, wherein a personal computer is provided with the management unit.

### Claim 3 (depends on 1)

The method to claim 1, wherein the injection molding machine is provided with the management unit.

### Claim 4 (depends on 1)

The method according to claim 1, further comprising storing, in a mold file in the storage unit, the list of the correct combination of the screen settings and the limiting operation of the injection molding machine, and
wherein the limiting operation of the injection molding machine includes prohibiting operation of an automatic operation until a confirmation completion of all setting states.

### Claim 5 (depends on 1)

The method according to claim 1,
wherein the storing the setting state of the injection molding machine includes determining a plurality of items for which setting confirmation is to be performed and sequentially registering a confirmation condition for each of the plurality of items, and
wherein in the comparing, the confirmation unit compares the information of the screen setting storage unit and the information of the storage unit with respect to each of the items so as to confirm the propriety of the combination of the screen settings of the injection molding machine.

### Claim 6 (depends on 5)

The method according to claim 5, wherein the items include two or more different items selected from a mold heater, process monitoring, confirmation of retraction of an ejector, a mold temperature controller, a picker, and a defective product alarm.

### Claim 7 (depends on 2)

The method according to claim 2, further comprising storing, in a mold file in the storage unit, the list of the correct combination of the screen settings and the limiting operation of the injection molding machine, and
wherein the limiting operation of the injection molding machine includes prohibiting operation of an automatic operation until a confirmation completion of all setting states.
