Description

  The present invention relates to an injection molding machine and relates to setting and changing molding conditions.

  In order to mold a molded product with an injection molding machine, it is necessary to set various molding conditions for each process of injection, filling, holding pressure, weighing, mold opening, mold closing, and mold clamping. The molding conditions to be set are large. Moreover, in order to obtain a good molded product, it is necessary to perform a condition setting operation for changing and adjusting the molding conditions by observing the molded product molded by the trial firing while repeating the trial firing. Since this condition setting operation is difficult and takes a long time, a storage device for an injection molding machine is used in which a set of set values of all molding conditions when a good molded product is obtained corresponds to the mold or molded product used. Or when it is stored in a storage device or storage medium outside the injection molding machine and then molded using this mold (when molding the same molded product), it corresponds to that mold or molded product. In general, a set of molding condition setting values stored in advance is read from a storage device, and the read molding condition setting values are automatically collectively set in an injection molding machine (Patent Documents 1, 2, and 3). reference).

  In general, a set of molding conditions stored in a storage device or an external storage medium is stored for each mold, that is, for each molded product. However, a plurality of sets of molding conditions are created for the same mold. Each set of molding conditions may be stored, but in this case as well, any one set of molding conditions corresponding to the mold is selected and the molding conditions are automatically set. As described above, the molding conditions generally change in conjunction with the replacement of the mold and are automatically set.

  However, among the setting items of the molding conditions set in the injection molding machine, there are setting items that are not linked to mold replacement such as manned / unmanned operation mode, heater disconnection detection value, load cell pressure correction confirmation, etc. There are setting items that are determined from conditions other than the mold, such as a molding condition setting item that should not be changed even if the mold changes, and a machine state that is output to the alarm lamp and a timer that uses a calendar function. For such setting items, it is necessary not to change the setting value even when the setting value is set by reading the molding conditions from the storage device in conjunction with the mold replacement or the like. As described above, among the setting items of the injection molding machine, there are a setting item whose setting value changes in conjunction with a setting item whose setting value changes when the molding condition is read from the storage device, and a setting item which does not change.

  As an example to clarify this distinction, the molding conditions determined by the mold and other molding conditions are stored separately, and the molding conditions determined by the mold are attached with a mold ID to correspond to the mold. When the mold is replaced, the molding conditions determined by the mold used are read and set in a batch, and when the molding conditions are displayed, the molding conditions determined by the mold or other molding There is also known an invention in which the condition is displayed separately (see Patent Document 4).

  Furthermore, the molding conditions are already set in the injection molding machine, and when the molding conditions stored in the external or internal memory are read and changed, the temperature data stored in the external or internal memory is included. It is possible to select whether to read all molding condition data and replace it with this molding condition, or to read and set only data other than temperature data among molding conditions stored in the external or internal memory. This invention is also known (see Patent Document 5).

JP 59-158237 A JP 60-196324 A JP-A-61-248722 JP 2006-95760 A JP 2001-322150 A

  Whether or not the setting value of a setting item of a certain molding condition changes the setting value in conjunction with the reading operation of the molding condition when the molding condition is read from the storage device and the setting value is collectively set, is determined by the injection molding machine manufacturer. Generally, it is determined by design. However, when reading the setting values of the setting items of each molding condition from the storage device and performing batch change settings, depending on the setting items, if you want to use the setting values that were previously set for the injection molding machine without changing the setting values There is. For example, when you want to fix the machine operation after the shutdown sequence, or when you want to fix the monitor item that performs pass / fail judgment, the mold changes, and the molding conditions corresponding to that mold are read and set In some cases, it may be desirable not to change the setting values for these setting items.

Furthermore, when the molding conditions confirmed by the mold creation department at the time of mold completion are the master conditions, and this master conditions are transferred to the mass production factory together with the molds, certain factory conditions are There are cases in which it is desired to keep the setting value fixed and not change. In such a case, if the master condition is set as it is, the setting values of all setting items of the molding condition are changed to the master condition.
For this reason, when reading the molding conditions and setting the set values at once, it is desirable to be able to select the setting items to be fixed without changing the set values.

  On the other hand, when the setting item for fixing the setting value can be selected, a phenomenon occurs in which the setting value of the setting item for fixing the setting value changes. There are cases where setting items are related to each other in the molding conditions. If you select and set a setting value for such a setting item as a setting item, this setting value is fixed. Since the setting values of the setting items are not changed, there may be a conflict between the setting values of the related setting items. There are cases where the optimum molding condition setting value cannot be set.

  As the above-described setting items related to each other, for example, it is necessary to set the ejection start position (the position of the movable mold at which the ejection operation starts) until the mold opening completion position of the movable mold is reached. is there. If you do not want to change this setting item, which is the eject start position, read the set of molding conditions that have a mold opening completion position smaller than the fixed eject start position from the storage device, and fix the set value. If setting items that have not been set (including setting items for the mold opening completion position) are collectively changed and set, an inconsistency occurs that the eject start position becomes larger than the mold opening completion position.

In addition, when function 1 and function 2 are functions that are not enabled at the same time, when function 1 is enabled and fixed, function 2 is also enabled when a set of molding conditions is read and set values are set. Occurs.
Accordingly, an object of the present invention is to select and set a setting item that does not change the set value when the set value of all molding conditions is read from the storage unit and the read setting value of the molding condition is set as an execution set value. An object of the present invention is to provide an injection molding machine.

  Furthermore, since setting items that do not change the setting value are selected and set, and there are setting items that are related to each other, the setting items that are selected and set when the setting value is fixed are stored in the injection molding machine. It is an object to prevent the setting values of all setting items from being changed when the value and the setting value read from the storage means are different. If this setting value is different, if the setting value is fixed without changing, the setting value other than the setting item that has been set is changed to the setting value read from the storage means, or the setting values of all setting items are changed. It is also an object of the present invention to make it possible to select whether or not to perform setting.

  The invention according to claim 1 of the present application has display means and data input means, displays a molding condition setting screen on the display means, and sets values for the setting items of the molding conditions displayed on the molding condition setting screen. In an injection molding machine equipped with a display setting means that can set a set of molding conditions stored in the storage means, and can set the set values of all the read molding conditions collectively, The display setting means reads out the set of molding conditions from the storage setting means, the equipment setting means for setting to the equipment setting that cannot change the setting value for the setting item, and canceling the equipment setting. When setting the setting values of all molding condition setting items at once, the equipment setting means discriminates the items set in the equipment settings and changes the setting values for the items set in the equipment settings. Do not do It provided the Unisuru control unit, not modified settings for equipment set setting item when collectively setting the set values of the molding conditions, and to be fixed to the previous settings.

  In the invention according to claim 2, the control means changes the setting values of the setting items other than the items set as the equipment settings to the setting values of the molding conditions read from the storage means. In the invention according to claim 3, for the item set as the equipment setting in the control means, does the set value set in the injection molding machine match the set value read from the storage means? Judgment means for judging is provided, and when the judgment means judges that they do not match, the control means does not change setting values of setting items other than equipment settings.

  Furthermore, in the invention according to claim 4, when the setting value set in the injection molding machine in the setting item set as the equipment setting does not match the setting value read from the storage means, the setting other than the equipment setting item is set. A means for selecting whether or not to change the setting value of the item is provided, and the control means is set in the injection molding machine for the setting item set as the equipment setting. A determination unit is provided for determining whether the setting value matches the setting value read from the storage unit, and the control unit selects a mode for changing the setting value of the setting item other than the item of equipment setting. Changes the setting value of the setting item other than the item of the equipment setting, and when the mode not to be performed is selected, the determination means sets the setting value in all the items set in the equipment setting. There was to change the setting value of the setting items other than the items of equipment set only when there is a match.

  In the invention according to claim 5, the display setting means is provided with an authentication password discrimination means for discriminating a match between the input password and the registration authentication password, and the input password and the registration authentication are determined by the authentication password discrimination means. When it is determined that the passwords match, it is possible to set and cancel the equipment settings for the setting items by the equipment setting means. Further, the invention according to claim 6 determines whether or not a password that can change the setting value of the setting item of the equipment setting is input to the display setting means, and when the password is input, the setting item of the equipment setting The setting value changing means of the equipment setting that can change the setting value is provided.

  The invention according to claim 7 enables the input / output of the information of the setting item set as the equipment setting by the display setting means. According to an eighth aspect of the present invention, the display setting means is provided in a control device of an injection molding machine, and the invention according to the ninth aspect provides the display setting means outside the injection molding machine. It was provided and connected to the control device of the injection molding machine.

  When setting items for molding conditions are set to equipment settings, when setting values for all molding conditions are read from the storage means and set collectively, the setting values for equipment setting items are not rewritten. Since the previous setting value is fixed, it is possible to prevent a setting item whose setting value should not be changed from being changed without being aware of it. Also, when the setting value of the item set in the equipment setting is different from the setting value already set in the injection molding machine and the setting value to be read and changed from the storage means, setting of setting items other than equipment setting It is possible to prevent the setting value from being inconsistent with the relevance when there is a relevance between the setting items of the molding conditions without changing the value.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a principal block diagram of a control device that controls the injection molding machine according to the first embodiment of the present invention. The configuration of the injection molding machine and the hardware configuration of the control device that controls the injection molding machine are the same as those of the conventional injection molding machine, and the setting items described later are set in the equipment settings and stored in the storage means. Since only the processing software for setting the molding conditions is different, only the main part of the configuration of the control device for controlling the injection molding machine is simply described in FIG.

The control device 10 for controlling the injection molding machine is provided with a processor (CPU) 11 for overall control, a storage means 12, an axis control means 13, a display device / input means 14, and an interface 15 in the same manner as a conventional control apparatus. 16 is connected.
The storage means 12 stores software for controlling the injection molding machine and various set values. In relation to the present invention, processing software for setting the setting item to equipment setting and processing for setting the molding conditions stored in the storage means are stored in the storage means 12. Furthermore, it has a memory | storage part which memorize | stores the setting value of the molding conditions to perform. Data such as a molding condition setting screen displayed on the display screen of the display device / input means 14 is also stored. Further, in association with the mold, each set value of the molding conditions used for the mold is stored as a set as a mold file. In addition, when there are a plurality of sets of set values for each molding condition for the mold, the mold file is stored in a distinguished manner. The mold file is not stored in the storage means 12 but is stored in the external storage device 20, and a set of molding conditions is read out from the mold file via the interface 15 and executed. It may be set in the condition storage unit.

The shaft control means 13 controls the position and speed of a servo motor that drives each mechanism such as a mold clamping mechanism, an injection mechanism, and a metering mechanism of an injection molding machine, and is a position / speed detector attached to the servo motor. The position and speed feedback control is performed based on the feedback signal from the controller 11 and the movement command output from the processor 11 to drive and control each mechanism.
The display device / input means 14 includes a display device such as a CRT or a liquid crystal display and data input means such as a keyboard and a pointing device, and is configured to input various setting values to be described later. In the present embodiment, processing for setting the setting items stored in the display device / input means 14 and the storage means 12 included in the control device 10 of the injection molding machine to equipment settings, and molding conditions stored in the storage means. The display setting means is configured by processing software for setting.
The interface 15 is connected to a sensor or an actuator provided in the injection molding machine, but is connected to a storage device 20 provided outside in connection with the present invention.

Among the setting items of the molding conditions, the setting item that is a fixed value that cannot be changed is set as the equipment setting item. Only the specific operator who entered the authentication password that permits the equipment setting of the setting item is permitted to perform the work to set the equipment setting item and the work to release the equipment setting and change the setting value. Yes.
Therefore, when setting / canceling the equipment setting for the setting item, the input means of the display device / input means 14 is operated, and the equipment setting lock screen as shown in FIG. Display. When a password is entered in the password entry field 30 designated on this screen, the processor 11 determines whether or not the entered password matches the previously registered and stored authentication password. As shown in b), the “equipment setting unlock” button 31 is displayed.

By pressing the “equipment setting unlock” button 31 (click the button 31 with the pointing device or select the button 31 with the cursor and operate the enter key. Hereinafter, the operation of pressing the button is the pointing operation. (It means that the button is operated and input with a device or a cursor), and the display changes to the display screen as shown in FIG. 2 (c), and it is asked whether or not to cancel the equipment setting lock “Yes”, “No” Buttons 32a and 32b are displayed. When the “yes” button 32a is pressed on this screen, “change start” and “initialization” buttons 33a and 33b are displayed on the display screen, as shown in FIG. Note that FIG. 2D shows only the lower “group setting” column in FIG. 2C, and the upper part is also displayed, but is omitted in FIG. 2D.
When the “change start” button 33a is pressed, the display of the button becomes “apply change”, and thereafter, the setting of the equipment setting and the release thereof are set for each setting item of the forming condition on the forming condition setting screen. It becomes possible.

  FIG. 3 is an example of a molding condition setting screen. Of the setting items of each molding condition, the background of the setting value setting column is displayed in gray for the item set as the equipment setting. In FIG. 3, the background of the setting value of the setting item indicated by reference numeral 34 is displayed in gray to indicate that the item is set to the equipment setting, and the background of the setting column is the normal setting item that is not the equipment setting. Displayed in white.

  Therefore, by selecting a setting item with a pointing device such as a cursor and pressing the equipment setting protection button 35a and the equipment setting protection release button 35b, the selected setting item can be set as an equipment setting item or an equipment setting item. Change to the normal setting item. That is, when the equipment setting protection button 35a is pressed, the selected setting item is set as an equipment setting item, and the setting value cannot be changed. Also, when an equipment setting item is selected and the equipment setting protection cancel button 35b is pressed, the equipment setting is canceled and the setting item becomes a normal setting item, and the setting value can be changed.

Thus, when the equipment setting is set for the molding condition setting item, whether or not the molding condition setting item is the equipment setting for each molding condition ID number as shown in FIG. The equipment setting storage table T for storing the information is created.
Then, after the equipment settings are selectively set for the setting items for each molding condition, the setting values of the setting items set for the equipment cannot be changed, the mold of the injection molding machine is replaced, and the storage means 12, when a set of molding conditions for the mold stored in 12 is read out and set as an execution molding condition at a time, the processor 11 searches the equipment setting storage table T, and for the items in which the equipment is set, Without changing to the read set value, the set value that has already been set is held and fixed, and only the setting items that are not set as equipment are changed to the read set value and set. When the injection molding machine is operated, the injection molding machine is operated under the setting conditions thus set.

FIG. 5 is an algorithm showing an operation flow showing the setting / cancellation processing of the equipment setting for the setting items of each molding condition.
As described above, when the operator selects the equipment setting lock screen as shown in FIG. 2A and displays it on the display device, and the password is input, the processor 11 registers this input password. If the input password and the authentication password match, the display screen as shown in FIG. 2B is displayed. When the “equipment setting unlock” button 31 is operated, the display screen is displayed. When the state is switched to the state shown in FIG. 2C and the “Yes” button 32a for instructing to release the equipment setting lock is pressed, a process for switching to the display screen shown in FIG. 2D is performed (step 100). When the change start button 33a is pressed, the processor 11 switches to the equipment setting mode (step 101).

  When the operator selects the molding condition setting screen, the processor 11 displays the selected molding condition setting screen. At this time, the processor 11 searches the equipment setting storage table T and sets to display it. It is determined whether the item is set to equipment setting. If the setting is set to equipment setting, the background of the setting value setting field of that setting item is gray and the setting value currently set as the execution molding condition is set. indicate. For setting items that are not set in the equipment setting, the current setting value is displayed with the setting field white (step 102).

  On the displayed molding condition setting screen, the operator selects a setting item and operates the equipment setting protection button 35a or the equipment setting protection release button 35b to set or cancel the equipment setting for the selected setting item. The processing is executed, and the processor 11 updates the storage content of the equipment setting storage table T depending on whether the setting item is set to the equipment setting or canceled, and the molding condition of the setting item for which the equipment is set is the equipment setting. It is stored, and in the molding condition of the setting item that is not the equipment setting, it is stored that the equipment setting is not set (steps 103 and 104).

When the registration process of the equipment setting on the setting screen is finished and another setting screen is selected (step 105), the selected setting screen is displayed on the screen of the display device (step 108). Set to and release it.
Then, the operator inputs an equipment setting process end command, and selects setting value change processing for setting items other than the equipment set items. In this embodiment, when a set of molding condition setting values is read from a mold file and set as an execution molding condition, two setting value setting methods for setting items other than equipment set items are changed. One of the processes can be selected. In the setting value change processing mode A, setting items other than the items set for equipment are all changed to setting values read from the mold file. In addition, the set value change processing mode B is a set value and mold that are set as execution molding conditions set in the injection molding machine at this point in any one of the items set in the equipment. If the setting value is different from the setting value read from the file, the setting value change setting process for all molding conditions is not executed, and the setting value for the actual molding condition is set as the previous setting value and the equipment setting item is set. When all the setting values of the execution molding conditions set in the injection molding machine match the setting values read from the mold file, change setting processing of all molding condition setting values is executed. .

In the molding conditions, there is no relationship between the equipment setting and the set item and other setting items, and the setting value of the item set in the equipment setting does not affect the setting value of other setting items. Or when there is no influence from the setting values of other setting items, or there is a relationship between the equipment settings and the set items and other setting items, and the setting values of these setting items affect each other. Even if it becomes a problem, this relationship may be disrupted, so if you change the setting values of setting items other than equipment setting items and manually correct the setting values to operate the molding machine, change the setting values. Processing mode A is selected.

  In addition, when one of the items of molding conditions related to each other is set as equipment, when setting and reading a set of molding conditions, the set value of the item set as equipment is set so as not to break the relationship. When the operation method of the injection molding machine is to be performed without changing any setting items other than the equipment setting items, the setting value change processing mode B is selected. Thus, in the present embodiment, the setting value change processing mode A or B can be selected.

  The items set in the equipment settings in the processes of Steps 103 and 104 are not related to the setting items not set in the equipment settings, and the setting values of the items set in the equipment settings are the equipment settings. If it is determined that the setting value of the setting item that has not been set is not affected, or if it is selected that the setting value should be corrected manually even if there is an effect, the operator can change the setting value. Mode A is selected so that the setting values of the setting items other than the items set in the equipment settings can be changed and set to the setting values read from the mold file. On the other hand, there is a relation between the item set in the equipment setting and the setting item not set in the equipment setting, and the setting value of the item set in the equipment setting becomes the setting value of the setting item not set in the equipment setting. In a case where it is determined that the operation is to be influenced, the operator selects the setting value change processing mode B so as to prevent inconsistency or error in setting values between related setting items.

  In step 106, the setting value change processing modes A and B are displayed on the display screen to prompt selection. When the operator selects one of the setting value change processing modes A and B, the equipment setting mode is turned off (step 107), and the equipment setting process is terminated.

FIG. 6 shows an algorithm of a mold file reading process when a set of molding condition setting values is read from a mold file stored in the storage means 12 or the external storage device 20 and stored as an execution molding condition. It is a flowchart to show.
When a mold file read command is input, the processor 11 starts the processing of FIG. 6 and first reads a set of molding condition setting values of the commanded mold file (step 200). Next, the index i is set to 0 (step 201), and it is determined whether any one of the setting value change processing modes A and B is selected and set (step 202).

  When the set value change processing mode A is selected, it is determined whether or not the setting item of the molding condition of the ID number IDi is set in the equipment setting from the equipment setting storage table T (step 203). The read setting value of the molding condition is stored in correspondence with the setting item as the molding condition to be executed (step 204). Also, when the setting item of the molding condition of ID number IDi is set to the equipment setting, the processing of step 204 is not performed, and the setting value of the molding condition of the setting item is not changed and has been set up to that point. Hold the setting value as it is and fix it as the setting value.

  Then, the index i is incremented by 1 (step 205), it is determined whether the index i exceeds the number N of setting items of the molding condition (step 206), and steps 203 to 206 are performed until the index i exceeds the number N of set items. Repeat the process to rewrite the molding condition setting values of the setting items not set in the equipment settings to the setting values of each molding condition read from the mold file, and for the items set in the equipment settings The molding conditions are set to the setting values that have been used up to now, without rewriting.

On the other hand, when it is determined in step 202 that the set value change processing mode B is selected, the process proceeds to step 207, where the setting item of the molding condition of the ID number IDi is set in the equipment setting from the equipment setting storage table T. If it is not set in the equipment setting, the process proceeds to step 209. Also, if set in the equipment setting, for the setting item of the molding condition of this ID number IDi, the setting value stored in the injection molding machine at the relevant time and the setting value stored in the injection molding machine, and the read out from the mold file It is determined whether the setting values of the setting items match (step 208). If they do not match and are different, the mold file reading process is terminated as it is. If they match, the process proceeds to step 209, where the index i is incremented by 1, and it is determined whether the index i exceeds the number N of setting items in the molding condition (step 210). If not, the process returns to step 207 to execute the processing after step 207. Hereinafter, unless there is a mismatch between the setting value set and stored as the execution molding condition in the injection molding machine and the setting value of the setting item read from the mold file, the processing of steps 207 to 210 is repeatedly executed, and the index i Is determined to have exceeded the number N of setting items of molding conditions (step 210), the setting items of all molding condition IDs 0 to _N are rewritten and changed to the setting values read from the mold file (step 211). ), The mold file reading process is terminated.

  As described above, in mode A, the items other than the items set in the equipment are set regardless of whether or not the set values of the current execution molding conditions of the items set in the equipment settings match the setting values read from the mold file. The setting value of the setting item is changed to the setting value read from the mold file and set as the setting value of the execution molding condition. In Mode B, only when the setting value read from the mold file matches the current execution molding condition setting value of the item set in the equipment setting, it is stored in the injection molding machine. As the execution molding condition setting values, change the setting values of all setting items to the setting values read from the mold file, and even one of the items set in the equipment settings is the current execution molding requirement If the set value set is different from the set value read from the mold file, the set value of the setting item of the molding condition is not changed. In this way, inconsistencies and errors in setting values between related items are eliminated.

As described above, in the present embodiment, when a password that allows setting / cancellation of the equipment setting for the setting item of the molding condition is input, the setting item can be set to the equipment setting or can be released. Therefore, when changing the setting value of an item that has been set for equipment, once cancel the equipment setting for that setting item, change the setting value, and then change to the equipment setting. do it.
However, as described above, when changing the setting value of a setting item that is set as equipment, it is inconvenient to cancel the equipment setting, change and input the setting value, and set the equipment setting again. An operator who can input a password that allows the setting / cancellation of the equipment setting can substantially change the setting value of the setting item that has been set for the equipment. The setting value of the setting item being set may be directly changed and set.

  In addition, there are cases where it is desired to change the setting values of the setting items that are set in the facility even if the setting / cancellation of the facility setting cannot be performed at the work site. Therefore, it is possible to provide a password that allows the setting value of the equipment setting setting item to be changed, and to change the setting value of the equipment setting setting item only to an operator who has input this password.

  In this case, when a password that allows the setting value of the setting item of the equipment setting to be changed is entered on the screen shown in FIG. 2A, FIG. 2B is displayed, and the button “Release equipment setting unlock” When the button is pressed, the screen shown in FIG. 2 (c) is displayed. Further, when the “Yes” button 32a for releasing the equipment setting lock is pressed, the screen shown in FIG. 2 (d) is displayed, and the “change start” button 33a is pressed. When pressed, the equipment setting lock is released, and the setting value in the equipment setting setting item on each molding condition setting screen can be changed. In this case, the facility setting cannot be set / released for the setting item, but only the setting value can be changed. The processing at this point is almost the same as the algorithm of the processing shown in FIG. 5, and only the processing at step 103 is changed to the setting value changing processing.

  In addition, when setting values of molding condition setting items are set and changed, and after the molding conditions to be used for actual molding are determined, the molding conditions are saved in the above-mentioned mold file etc. Regardless of whether or not it is set to, it is stored in the mold file.

  The information on the equipment setting storage table T described above, that is, information on whether or not the setting item is equipment set is output to the outside as a file and stored in the control device of another injection molding machine. The table T is made available for other injection molding machines. Thus, if one injection molding machine adjusts the molding conditions and sets whether or not the equipment is set, it can be used in other injection molding machines.

  In the embodiment described above, the display setting unit is configured by software stored in the display device / input unit 14 and the storage unit of the control device 10 that controls the injection molding machine, and the display setting unit sets the above-described molding condition setting items. However, instead of this display setting means, the setting / cancellation processing for the equipment setting and the setting items for the equipment setting are performed instead of the display setting means. Is executed by a display setting device composed of a personal computer or the like provided outside the injection molding machine, and finally obtained molding condition information (whether the equipment can be set and the set value) Etc.) may be sent and set to the control device of the injection molding machine.

FIG. 7 is a schematic view of a second embodiment of the present invention. In the second embodiment, a display setting device 21 configured by a personal computer is provided outside the injection molding machine, and a control device for the injection molding machine is provided. 10 is connected to the communication interface 17, and the display setting device 21 performs the setting / cancellation processing of the equipment setting, the setting value changing processing in the setting items of the equipment setting, and the setting processing of the setting values for the normal setting items. It is to be executed in.
The memory of the display setting device 21 is provided with a storage unit for storing molding condition setting screen data and setting values of setting items for each molding condition set as an execution molding condition of the injection molding machine at that time. In addition, an equipment setting storage table T is also provided. The mold file is stored in the memory of the display setting device 21 or stored in an external storage device (not shown) so that the display setting device 21 reads the molding condition information of the mold file from the storage device. It may be.

  By operating an input device such as a keyboard of the display setting device 21, it is possible to change the setting of the password or the setting item of the equipment setting that allows setting / canceling of the equipment setting via the display device of the display setting device 21. The user inputs the password to be operated and operates the "equipment setting unlock" button 31, the "yes" button 32a, and the "change start" button 33a (see FIG. 2).
