Description

[Technical Field]

[0001] The present invention relates to an injection molding machine, and more particularly to a technique for managing data according to molding conditions. [Background technology]

[0002] An injection molding machine is a device that produces molded products by injecting molten raw materials into a cavity.

[0003] The injection molding machine includes a mold for forming a cavity.

[0004] Injection molding machines come in a variety of types, including the standard type that fills a cavity with molten raw material to produce a molded product, and the blow molding type that injects air to produce molded products with special shapes such as cylinders.

[0005] Injection molding machines are typically used with a variety of accessories.

[0006] For example, the accessory equipment may be a temperature control device for adjusting the temperature conditions of the mold of the injection molding machine. Temperature control devices can be divided into those that control the mold temperature using an electric heater (especially when a hot runner is used) and those that control the mold temperature using cooling water.

[0007] For example, the accessory equipment may be a material supply device that supplies raw materials according to supply conditions.

[0008] For example, the accessory equipment may be a drawing robot device for drawing out the produced molded product according to drawing conditions.

[0009] In addition, various accessories can be added depending on the type of molding.

[0010] The set conditions set in the accessory equipment, such as the temperature conditions, the supply conditions, and the withdrawal conditions, can be commonly called molding conditions for molding an appropriate molded product.

[0011] In general injection molding, the quality of a molded product is highly sensitive to the molding conditions, so the molding conditions must be set to the optimum values ​​to produce a suitable molded product.

[0012] The molding conditions are determined by taking into account the basic data for producing the molded product, data applied in previous production, special issues that arise when using the injection molding machine, the current working environment of the factory, and the manager's experience.

[0013] Meanwhile, in recent years, injection molding machines have come to communicate with each other via a network, as shown in Figure 1. Therefore, the injection molding machine is equipped with a general setting device, and the auxiliary equipment is equipped with a unit setting device.

[0014] The general setting device and the unit setting device communicate with each other via a network N / W, and can be used by an administrator to input molding conditions or can be used to display molding conditions.

[0015] The manager can input molding conditions for each auxiliary equipment using a general setting device, or can input molding conditions for each auxiliary equipment using a unit setting device.

[0016] An example of setting a temperature value, which is one of the molding conditions, in the general setting device will be described with reference to FIG.

[0017] The screen provided by the general setting device has a current window PW, an input window IW, a setting window SW, and a setting button SB.

[0018] The current window PW displays the current temperature value currently measured by the auxiliary equipment, which may be, for example, the current temperature value of a hot runner attached to the mold.

[0019] The input window IW displays the first temperature value, which is the first molding condition, input by the manager via the general setting device of the injection molding machine.

[0020] The setting window SW displays a second temperature value, which is a second molding condition set in the unit setting device of the accessory equipment. Here, the second temperature value may be a value transmitted from the general setting device to the unit setting device, or a value individually input and set in the unit setting device by an administrator and then received by the general setting device. The accessory equipment then operates to comply with the temperature conditions according to the second temperature value in the setting window SW. For example, the accessory equipment operates so that the hot runner has the second temperature value in the setting window SW. Under normal and desirable conditions, the second temperature value is the same as the first temperature value.

[0021] The setting button SB is used to input a command from the manager to set the second temperature value of the accessory equipment to the first temperature value in the input window IW.

[0022] As shown in the reference diagram of FIG. 2, there are three ways for the administrator to set the temperature value of the auxiliary equipment.

[0023] One of the paths is a path for inputting a first temperature value using the general setting device. The administrator inputs the first temperature value (86.0) in the input window IW and then operates the setting button SB. The first temperature value (86.0) is then transmitted to the unit setting device via the network N / W, and the unit setting device sets the second temperature value to be the same as the first temperature value (86.0).

[0024] One of these paths is a path for importing the first temperature value (86.0) using the general setting device. When the manager imports the first temperature value (86.0) stored in the general setting device, the general setting device displays the imported first temperature value (86.0) in the input window IW. At the same time, the general setting device transmits the first temperature value (86.0) to the unit setting device, and the unit setting device sets the second temperature value to be the same as the first temperature value (86.0). Then, the set second temperature value (86.0) is transmitted from the unit setting device to the general setting device, and the general setting device displays the second temperature value (86.0) received by the unit setting device in the setting window SW.

[0025] One of the paths is a path for inputting a temperature value using a unit setting device, and the administrator can input and set a second temperature value using the unit setting device.

[0026] For reference, the second temperature value input by the unit setting device is transmitted to the general setting device via the network, and the general setting device displays the second temperature value (86.0) received by the unit setting device in the setting window PW. Here, the displayed value in the input window IW may differ from the displayed value in the setting window PW. In this case, the administrator corrects the first temperature value in the input window IW to be the same as the second temperature value (86.0) in the setting window PW, as necessary.

[0027] However, such a conventional method for setting molding conditions involves the following troubles.

[0028] First, the first shaping condition of the input window IW and the second shaping condition of the setting window SW may differ from each other.

[0029] For example, when the manager inputs and sets the second molding conditions through the unit setting device, the first molding conditions may differ from the second molding conditions as described above, and when the manager is replaced, it may be confused as to which of the first and second molding conditions is appropriate.

[0030] Second, when the manager newly inputs the second molding conditions on the unit setting device, the first molding conditions displayed in the input window IW on the general setting device must also be changed to the same as the second molding conditions to prevent confusion.

[0031] For example, when the first molding condition is displayed as 50 degrees in the input window IW and the second molding condition is displayed as 50 degrees in the setting window SW, the manager can set the second molding condition to 40 degrees using the unit setting device. The unit setting device then transmits the second molding condition to the global setting device, which then corrects the second molding condition in the setting window SW to 40 degrees. Therefore, the first molding condition (50 degrees) in the input window IW differs from the second molding condition (40 degrees) in the setting window SW. Therefore, to prevent confusion, the manager must correct the first molding condition in the input window IW to 40 degrees, the same as the second molding condition in the setting window SW. However, if there are many auxiliary devices, there will be many input windows IW and setting windows SW. Therefore, it may not be easy to compare the display values ​​displayed in the input window IW and setting window SW to identify the display value that needs to be corrected.

[0032] Furthermore, large-scale molds may have at least a dozen or even more than a hundred temperature setting zones. Therefore, as shown in the example screen S in FIG. 3, each temperature control zone has an input window IW and a setting window SW. Therefore, the task of inputting and correcting the first molding condition to be the same as the second molding condition while checking the displayed values ​​can be very tiring. Furthermore, it is easy to overlook this and miss the correction.

[0033] Third, errors may occur when saving molding conditions.

[0034] As described above, when the molding product changes, the molding conditions must also be changed along with the change of raw materials, molds, etc. However, the process of searching for and inputting molding conditions is very cumbersome. To eliminate this process, a general setting device is embodied to store molding conditions for the molded product produced.

[0035] However, if the second forming conditions displayed in the setting window IW are different from the second forming conditions displayed in the input window IW, confusion may occur during data storage. To prevent this, the general setting device is configured to store the first forming conditions displayed in the input window IW. However, since the second forming conditions in the setting window SW may be values ​​that are appropriately reflected during the operation of the auxiliary equipment, it is highly likely that the second forming conditions are appropriate forming conditions that correspond to the actual on-site situation. Therefore, the administrator must correct the first forming conditions displayed in the input window IW to be the same as the second forming conditions and then store the forming conditions. As mentioned above, this process can be very cumbersome.

[0036] In addition, if there are a large number of molding conditions, the data in the input window IW may not be corrected, which may result in incorrect molding conditions being saved, resulting in an error later on in which a molded product is produced based on the incorrect molding data.

[0037] [Patent Document 1] Korean Patent No. 10-2567133 Summary of the Invention [Problem to be solved by the invention]

[0038] The present invention was devised from the desire for a technique that can manage molding conditions so that disruptions are minimized. [Means for solving the problem]

[0040] When a synchronization command is input by operating the input means, the control means controls the synchronization portion to operate and execute synchronization.

[0041] When a save command is input by operating the input means, the control means operates the synchronization part to perform synchronization, and then controls the storage means to store the synchronized first molding conditions.

[0042] The control means further includes a notification portion that notifies the user that the first molding conditions and the second molding conditions are different via the output means when the comparison portion determines that the first molding conditions and the second molding conditions are different.

[0043] The notification portion outputs the first molding conditions and the second molding conditions on the screen of the output means so that they can be distinguished from each other by difference in color.

[0044] Among the molding conditions output by the output means, the first molding condition is any one of data taken from the storage means, data input by an administrator through the input means, and data synchronized by the synchronization part.

[0045] The screen output via the output means includes an input window that displays the first molding conditions input by the manager via the general setting device, and a setting window that displays the second molding conditions set in the unit setting device of the accessory equipment, and when the manager operates the input means to import the molding conditions stored in the storage means, the molding conditions imported from the storage means are automatically displayed in the input window and the setting window.

[0047] The notification portion outputs the first molding conditions and the second molding conditions on the screen of the output means so that they can be visually distinguished from each other. [Effects of the Invention]

[0048] The present invention has the following advantages.

[0049] First, it is very easy to match the molding conditions of the general setting device with those of the unit setting device.

[0050] Second, errors caused by incorrect data being saved during the process of saving molding conditions will no longer occur.

[0051] Third, there is almost no possibility of confusion occurring in setting and synchronizing molding conditions.

[0052] Therefore, ultimately, the management and setting of molding conditions can be convenient and accurate, thereby improving the reliability of the injection molding machine. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0054] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described with reference to the accompanying drawings. For the sake of brevity, descriptions of well-known or repeated components will be omitted or simplified as much as possible.

[0055] <Description of the First Example> FIG. 4 is a schematic diagram of an injection molding machine 100 according to one embodiment of the present invention.

[0056] As shown in FIG. 5, the injection molding machine 100 according to the present invention is installed so as to communicate with a number of accessory devices (accessory device 1, accessory device 2) via a network N / W.

[0057] The auxiliary equipment is attached to the molding device 110 and the injection device 120 that constitute the injection molding machine, and creates the molding environment necessary for producing molded products. However, for the sake of convenience, both of the auxiliary equipment shown in Figure 5 are assumed to be temperature control devices for controlling the temperature of the mold. That is, in this embodiment, the temperature value will be considered as the molding condition.

[0058] 5 shows only two accessory devices directly, more accessory devices may be provided to communicate with the injection molding machine 100. However, it is sufficient that the injection molding machine 100 according to the present invention is connected to at least one accessory device.

[0059] The injection molding machine 100 is equipped with a general setting device 130, and the auxiliary equipment is equipped with a unit setting device.

[0060] The general setting device 130 is for setting and managing molding conditions for all auxiliary equipment in a general manner, and the individual setting devices are for setting and managing molding conditions for individual auxiliary equipment, which will be described in detail later.

[0061] The injection molding machine 100 of FIG. 4 includes a shaping device 110, an injection device 120, and an overall setting device .

[0062] The molding device 110 can form a molding space by a mold or open a cavity C. The cavity C in this example has the same shape as the shape of the molded product.

[0063] When the molding device 110 forms the cavity C, a molten resin is injected into the cavity C, and then solidifies within the cavity C to produce a molded product.

[0064] When the forming device 110 opens the cavity C, the produced molding can be extracted.

[0065] After the forming device 110 forms the cavity C, the injection device 120 injects molten resin into the cavity C. To this end, the injection device 120 is configured to accommodate particulate raw materials, melt the accommodated particulate raw materials, and inject them into the cavity C.

[0066] The general setting device 130 is provided to set molding conditions for auxiliary equipment attached to the injection molding machine 100.

[0067] The general setting device 130 may be configured to set molding conditions for the injection molding machine 100 itself. For example, the general setting device 130 may be configured to set the mold opening / closing time of the molding device 110, the strength and application time of the holding pressure, and the operation time of the injection device 110. Therefore, the general setting device 130 may be embodied as one component of a control device that controls the overall operation of the injection molding machine 100.

[0068] The present invention is characterized by the overall setting device 130. Therefore, the overall setting device 130 will be described in more detail below.

[0069] As shown in FIG. 6, the general setting device 130 according to the first embodiment of the present invention includes a communication unit 131, a storage unit 132, an output unit 133, an input unit 134, and a control unit 135.

[0070] The communication means 131 is provided for communicating with an accessory unit setting device. That is, the general setting means 130 can perform communication for exchanging molding conditions with the unit setting device through the communication means 131. For example, a first temperature value, which is a first molding condition inputted in the general setting device 130, can be transmitted to the unit setting device through the communication means 131. And, a second temperature value, which is a second molding condition inputted and set in the unit setting device, can be received by the general setting device 130 through the communication means 131.

[0071] A storage means 132 is provided for storing molding conditions for the auxiliary equipment.

[0072] The storage means 132 stores molding conditions classified by mold applicable to the injection molding machine 100. This is because molding conditions may differ for each mold.

[0073] The output unit 133 can output molding conditions for the auxiliary equipment. The output unit 133 in this embodiment is embodied to output a screen S on which various related information can be visually recognized, as shown in FIG.

[0074] An input means 134 is provided for inputting molding conditions for the auxiliary equipment.

[0075] The input means 134 is also provided for inputting commands as required by the manager, such as setting molding conditions for auxiliary equipment, saving molding conditions, and executing synchronization.

[0076] According to a preferred embodiment of the present invention, the output means 133 and the input means 134 are implemented as a single touch screen. Therefore, molding conditions and instructions from the manager can be input on the screen S output by the output means 133. Of course, it is also possible to consider any configuration in which the output means 133 and the input means 134 are provided as separate objects.

[0077] For reference, the screen S in FIG. 7 is an example in which two accessory devices are applied.

[0078] Referring to FIG. 7, the screen S outputted through the output means 133 has a setting area SS and a mold area MS.

[0079] The setting area SS is provided for displaying molding conditions for auxiliary equipment or for inputting and setting molding conditions. To this end, the setting area SS is provided with a current window 133a, an input window 133b, a setting window 133c, a setting button 133d, and a production information window 133f. Here, the current window 133a, the input window 133b, and the setting window 133c must be provided separately for each auxiliary equipment.

[0080] The current window 133a displays the current temperature value currently measured by the accessory equipment. Here, the current temperature value may be, for example, the current temperature value for a specific point on the mold or the current temperature value of a hot runner attached to the mold.

[0081] In the input window 133b, the first temperature value, which is the first molding condition input by the manager via the general setting device 130, is displayed.

[0082] In addition, the input window 133b may be embodied to have an input function. For example, when the administrator touches the input window 133b with a finger (or a sensed tool, hereinafter referred to as a finger), an input display in the form of a scroll bar is generated, thereby enabling the administrator to input the first temperature value. In this way, when the administrator directly inputs the first molding conditions into the input window 133b, the first molding conditions displayed in the input window 133b are naturally data input by the administrator through the input means 134.

[0083] The setting window 133c displays the second temperature value, which is the second molding condition set in the unit setting device of the accessory equipment. Here, the second temperature value may be the first temperature value transmitted to the unit setting device from the general setting device 130. Alternatively, the second temperature value may be a value individually input in the unit setting device by an administrator, or may be a value received by the general setting device 130 from the unit setting device.

[0084] That is, the setting window 133c displays the second temperature value currently set in the unit setting device. Of course, the auxiliary equipment operates according to the second temperature value in the setting window 133c.

[0085] The setting button 133d is provided for setting a second temperature value of the accessory equipment. That is, the administrator can input a command to set the second temperature value of the accessory equipment through the setting button 133d. For example, when a user touches the setting button 133d with his / her finger, the general setting device 130 transmits the first temperature value in the input window 131b to the unit setting device. Then, the unit setting device corrects the second temperature value so that it is the same as the first temperature value. Therefore, the accessory equipment operates according to the second temperature value that has been corrected and set to be the same as the first temperature value.

[0086] The production information window 133f displays information about the mold currently applied to the injection molding machine 100. Therefore, the manager can check the mold currently applied to the injection molding machine 100 through the production information window 133f and roughly check whether the information in the setting area SS matches the mold.

[0087] The mold area MS is provided to display the molds and manage molding conditions for each mold.

[0088] Within the mold area MS, a list window 133g, an import button 133h, a save button 133i, and the like are provided.

[0089] The list window 133g displays a list of molds for which data on molding conditions has been saved up to now.

[0090] The import button 133h is used to import the temperature value of a specific mold from among the molds in the list window 133g and display it in the setting area SS.

[0091] For example, the manager can touch a specific mold with his / her finger in the list window 133g, and then touch the import button 133h with his / her finger. That is, the manager can operate the input means 134 to input a command to import molding conditions for the specific mold stored in the storage means 132. Then, the general setting device 130 imports the temperature value, which is the molding condition for the specific mold stored by the storage means 132, as the first temperature value and displays it in the input window 133b. That is, the first molding condition displayed in the input window 133b can be data imported from the storage means 132. Of course, the newly imported mold is also displayed in the production information window 133f.

[0092] In addition, the general setting device 130 transmits the temperature value of the specific mold retrieved from the storage means 132 to the unit setting device. Thus, the unit setting device sets the temperature value of the specific mold to the second temperature value, and the auxiliary equipment operates in accordance with the set second temperature value.

[0093] Of course, the loading button 133h can be used appropriately when the injection molding machine 100 is operated again after a pause or when the mold is replaced.

[0094] The save button 133i is used to save the molding conditions for the current accessory equipment.

[0095] The save button 133i can be used to save the molding conditions, which are the factors that provide the current molding environment, in connection with the mold when the administrator determines that the current molding environment is the optimal state for obtaining the highest quality molded product.

[0096] For example, the manager can input a save command by touching the save button 133i with his / her finger. That is, the manager can input a command to save the molding conditions by operating the input means 134. Then, the general setting device 130 associates and saves the same second temperature value as the currently set second temperature value in the auxiliary equipment with the currently applied mold. This process will be described in more detail.

[0097] According to the first embodiment, the temperature value stored by the storage means 132 is the first temperature value displayed in the input window 133b. However, after the on-site manager corrects and sets the second temperature value in the unit setting device, the first temperature value may not be corrected in the global setting device. This may result in the first temperature value displayed in the input window 133b differing from the second temperature value set in the accessory equipment, which is the optimal temperature value. Since the second temperature value set in the accessory equipment is displayed in the setting window 133c, the first temperature value displayed in the input window 133b may differ from the second temperature value displayed in the setting window 133c. In this case, the global setting device 130 first corrects the first temperature value displayed in the input window 133b to be the same as the second temperature value displayed in the setting window 133c, and then stores the first temperature value corrected to be the same as the second temperature value and displayed in the input window 133b.

[0098] On the other hand, the control means 135 controls the communication means 131 , the storage means 132 , and the output means 133 through the operation of the input means 134 .

[0099] According to a first embodiment, as shown in FIG. 8, the control means 135 comprises a comparison part 135a and a synchronization part 135b.

[0100] The comparison section 135a compares and verifies whether the first temperature value, which is the first molding condition, and the second temperature value, which is the second molding condition, are the same or different. Here, the first temperature value is the value displayed in the input window 133b, and the second temperature value is the value displayed in the setting window 133c after being received from the unit setting device.

[0101] The synchronization part 135b matches the first temperature value, which is the first molding condition, to the second temperature value, which is the second molding condition, i.e., changes (hereinafter referred to as "synchronization") the first molding condition so that the value of the first molding condition is the same as the value of the second molding condition.

[0102] According to the first embodiment, the synchronization section 135b operates when the administrator places his / her finger on the save button 133i to save the molding conditions, i.e., when the administrator operates the input means 134 to input a command to save the molding conditions.

[0103] Next, the characteristic operation of the injection molding machine 100 according to the present invention will be described based on an example of use of such an injection molding machine 100.

[0104] With the molding conditions set and the injection molding machine 100 operating together with the auxiliary equipment, the manager can modify and set the second temperature value in the unit setting device, taking into consideration the specific conditions of the injection molding machine 100 and the auxiliary equipment, various surrounding environments, etc. Here, the set second temperature value may be different from the first temperature value displayed in the input window 133b of the general setting device 130. Then, the unit setting device transmits the modified second temperature value to the general setting device 130. Therefore, the control means 135 modifies the second temperature value in the setting window 133c to the second temperature value received from the unit setting device.

[0105] Therefore, as shown in FIG. 9, the second temperature value (40.0) displayed in the setting window 133c assigned to the accessory equipment 2 differs from the first temperature value (50.0) displayed in the input window 133b.

[0106] The manager can then operate the save button 133i with his finger to save the current molding conditions. The control unit 135 then activates the comparison section 135a to compare the first temperature value (50.0) displayed in the input window 133b with the second temperature value (40.0) displayed in the setting window 133c. Through this comparison, the control unit 135 determines that the first temperature value (50.0) and the second temperature value (40.0) are different. In this case, the control unit 135 activates the synchronization unit 135b to synchronize the first and second temperature values. Of course, the synchronization causes the first temperature value displayed in the input window 133b to be the same as the second temperature value displayed in the setting window 133c. Therefore, after synchronization, the first temperature value (40.0) displayed in the input window 133b and the second temperature value (40.0) displayed in the setting window 133c become the same. That is, after synchronization by the synchronization portion 135b, the first forming condition displayed in the input window 133b is synchronized data having a value that matches the second forming condition.

[0107] When the synchronization is completed, the control means 135 controls the storage means 132 to link and store the mold information displayed in the production information window 133f and the first temperature value displayed in the input window 133b. The stored data can be reused later by importing it.

[0108] <Second Example> According to the second embodiment, an administrator can input a command for executing synchronization by operating the input means 134. For example, the second embodiment can be implemented in a form in which a synchronization button 133e is displayed on a screen S output by the output means 133, as shown in FIG.

[0109] The synchronization button 133e is provided for matching the first temperature value, which is the first molding condition displayed in the input window 133b, with the second temperature value, which is the second molding condition displayed in the setting window 133c, according to an administrator's command. Of course, matching the first temperature value with the second temperature value is achieved by synchronization, which modifies the first temperature value to be the same as the second temperature value.

[0110] For example, the administrator can operate the synchronization button 133e with a finger to input a synchronization command. Then, the control unit 135 first activates the comparison unit 135a to compare the first temperature value displayed in the input window 133b with the second temperature value displayed in the setting window 133c to determine whether they are identical. If the first and second temperature values ​​are not identical, the control unit 135 activates the synchronization unit 135b to perform synchronization, and then controls the output unit 133 to correct the first temperature value in the input window 133b to match the second temperature value in the setting window 133c and display it. In other words, the administrator can easily correct the first temperature value via the synchronization button 133e, instead of having to go through a separate, cumbersome input process to correct the first temperature value.

[0111] Furthermore, as shown in Fig. 10, when the manager operates the synchronization button 133e, the molding conditions for all the auxiliary equipment are synchronized at once. Therefore, as shown in Fig. 10, there is no molding condition that cannot be synchronized and is therefore omitted during the synchronization process.

[0112] However, depending on the implementation, each accessory device may be provided with a separate synchronization button.

[0113] <Third Example> According to the third embodiment, synchronization is performed when saving molding conditions, as in the first embodiment. In addition, as in the second embodiment, a synchronization button 133e is provided on the input means 134 to support the usage pattern of the second embodiment.

[0114] That is, the third embodiment is realized as a combination of the first and second embodiments.

[0115] <Fourth Example> According to the fourth embodiment, as shown in FIG. 11, the control means 135 includes a comparison portion 135a and a notification portion 135c.

[0116] The comparison section 135a compares the first temperature value, which is the first molding condition, with the second temperature value, which is the second molding condition, to determine whether the first temperature value and the second temperature value are the same or different.

[0117] If the first temperature value and the second temperature value are different, the notification section 135c notifies the user that the first temperature value and the second temperature value are different via the output means 133. The administrator can then confirm the notification by the notification section 135c, correct the first temperature value to the second temperature value, and input the corrected value.

[0118] According to the fourth embodiment, as shown in Fig. 12, when the first temperature value (50.0) in the input window 133b and the second temperature value (40.0) in the setting window 133c are different, the background color of the setting window 133c is displayed in a different chromatic color (e.g., red or blue) from the background color of the input window 133b. Of course, the background color of the input window 133b can also be displayed in a different chromatic color from the background color of the setting window 133c. Of course, the colors of the characters displayed in the input window 133b and the setting window 133c can be different, or the types of lines can be different. In other words, the notification portion 135c outputs the first temperature value (50.0) and the second temperature value (40.0) on the screen S of the output means 133 so that they are visually distinguishable from each other. For example, by using different text colors for the first and second temperature values ​​or different background colors for the first and second temperature values, the administrator can easily confirm that the first temperature value (50.0) and the second temperature value (40.0) are different based on the difference in color perception.

[0119] For reference, the fourth embodiment can be implemented in combination with any one of the first, second, and third embodiments. In this case, as shown in Fig. 13, the control unit 135 includes a comparison unit 135a, a synchronization unit 135b, and a notification unit 135c.

[0120] <Fifth Example> The fifth embodiment involves retrieving stored data.

[0121] When the administrator selects a specific mold from the molds in the list window 133g and then operates the import button 133h, data about the specific mold is loaded into the setting area SS. An example of this will be described with reference to FIG.

[0122] For example, if the administrator selects mold B and then operates the import button 133h, data on the molding conditions for mold B will be displayed in the input window 133b and setting window 133c of the setting area SS. More specifically, if the saved molding condition for mold B is a temperature value of 50 degrees, 50 degrees will be displayed in the input window 133b as the first temperature value, which is the first molding condition. The first temperature value (50 degrees) entered in the input window 133b is then automatically transmitted to the unit setting device. The unit setting device is then set to 50 degrees, and the associated equipment operates to match the converted molding condition of 50 degrees. Therefore, the displayed value in the current window 133a will approximate the values ​​in the input window 133b and setting window 133c.

[0123] Furthermore, as a result of the import, the first temperature value in the input window 133b is displayed as 50 degrees, and the second temperature value in the setting window 133c is also automatically displayed as 50 degrees. In other words, when importing is performed, the imported molding conditions are automatically displayed together in the input window 133b and the setting window 133c.

[0124] <Additional Information> The present invention is more preferably applicable to a case where there are many auxiliary devices and many input windows 133b and setting windows 133c than to a case where there are few auxiliary devices and few input windows 133b and setting windows 133c.

[0125] Furthermore, when a mold is equipped with a hot runner with multiple zones (e.g., 10 or more zones), an input window 133b and a setting window 133c must be provided for each zone. That is, the number of input windows 133c and setting windows 133c increases in accordance with the number of zones. Therefore, the more a mold is used that is equipped with a hot runner with multiple zones, the more preferable the present invention is to prevent confusion in data management.

[0126] The above-described embodiments have been described based on preferred examples of the present invention, and various application forms are possible. Therefore, the present invention should not be understood as being limited to the above description. Instead, the scope of the present invention should be understood as the scope of the separately described claims and their equivalents.
