In any of the above cases, the conventional maintenance is to manage the number of shots for one die. However, as will be described later, the mold is composed of a plurality of parts, and each part does not have the same life. Then, in a factory equipped with a plurality of injection molding machines for molding a large number of the same molded products, a sudden failure occurs in a mold of an injection molding machine, for example, when a part with a mold has a failure, In some cases, the same part removed from another mold may be substituted. In this case, parts that contributed to molding of another shot number are mixed in the mold that contributed to molding of a certain shot number, which is a problem in shot number management. In other words, in the above case, it is impossible to know the periodic maintenance time and life, and the mold failure must be dealt with only when the mold actually fails or the molding defect caused by the mold occurs. become. If a mold suddenly breaks down or a molding defect occurs due to the mold, the production plan is greatly delayed, and problems such as out-of-stock items occur.

Therefore, an object of the present invention is to provide a mold management system for realizing preventive maintenance against a failure of the mold by automatically managing the mold for each part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Before describing the embodiments of the present invention, the embodiments described below specialize the application to an injection molding machine, and particularly manage a plurality of injection molding machines collectively. It is premised that it will be applied in combination with a multiple unit management system. Therefore, first, a system for managing a plurality of injection molding machines will be described.

FIG. 3 shows the configuration of a system for managing a plurality of injection molding machines. In FIG. 3, a plurality of injection molding machines 10-1 to 10-n are installed in a factory 100, and the plurality of injection molding machines 10-1 to 10-n are provided with a management device 20. It is managed collectively in. That is, the management device 20 is connected to the respective control devices in the injection molding machines 10-1 to 10-n, and various control signals from various sensors installed in the injection molding machines 10-1 to 10-n are used. Information is received via each control device, the received information is processed for each injection molding machine based on a built-in management program, and the processed result is stored in a built-in memory and displayed on a display as a management screen. Of course, the received raw information may be stored in the memory as it is depending on the type of information.

In particular, this multi-unit management system is used in the factory 1
If there is a manufacturer of the injection molding machine (or a management center of the manufacturer) or another factory managed by a similar multiple-unit management system in a remote place away from 00, the manufacturer and another factory respectively use the Internet. Factory 1 by accessing the Web server via a communication network such as
The specific information in the management device 20 in 00 can be acquired. Alternatively, the factory 100
A multi-unit management system in a factory and a multi-unit management system in another factory are LAN (Local Area Ne
It is possible to configure such that specific information can be mutually acquired even when communication connection is possible in a network such as a network.

As well known, the Web server generally operates according to HTML.
However, it may be one that can handle CompacHTML data or the like that defines a Web service for a mobile phone, for example. In any case, this kind of Web
The server includes a processor and a memory, and the processor executes a program stored in the memory,
The operation of the Web server is realized. Memory is also a temporary storage location for data that the processor outputs while it is executing a program.

Of course, in order to prevent access from a completely unrelated communication terminal device, an ID number or password is given to the communication terminal device that can access the Web server in advance.

Next, the management device 20 of the multiple-device management system
In the following, four examples out of a plurality of types of screens displayed to represent the management status of each injection molding machine will be described.

FIG. 4 is an operation status screen for displaying the operation status of a plurality of injection molding machines in real time. On this operation status screen, the operation status of a plurality of injection molding machines is displayed in real time on a single screen in a screen-divided format for all machines (here, machines 1 to 30). For example, referring to FIG. 5, which is an enlarged view of the No. 9 machine, the number of the No. machine is shown in the upper left, the count value of the molding condition change counter (here, 17) is displayed in the molding condition change display section C1 in the upper right, and the right side The 24-hour operating status graph by the bar graph B1 is displayed, and the shot number (529) and cycle time (14.9 sec) are displayed on the lower side.

Here, the molding condition change counter is a counter for counting how many times the molding conditions have been changed from the start of molding to the present. This counter is provided in the management device 20. The control device of each injection molding machine is provided with a means for detecting a change in molding conditions, and the management device 20 counts each in response to the detection result from each control device, and displays the count result for each machine in the molding condition change display section. Display on C1. The management device 20 can reset this display value as needed.

Further, the 24-hour operation status graph is one in which the operation status of the injection molding machine from the present time to the past 24 hours is color-coded and displayed by one first bar graph B1. The operating status is defined by four types: operating, normal stop (during standby), stop due to an abnormality, and power off. The four types of status are displayed in different colors according to the elapsed time from 24 hours ago to the present time. To be done. Here, the operation is shown in blue, the normal stop is shown in yellow, the stop due to an abnormality is shown in red, and the power is turned off in gray.
Blue is shown with fine hatching to the right, yellow is vertical stripes, red is coarse hatching to the right, and gray is shown with hatching to the left. Further, the lowermost end of the first bar graph B1 indicates 24 hours ago, and the uppermost end indicates the current time. For example,
If it is a normal stop from the past 24 hours to 12 hours, and is operating from the past 12 hours to the present time, the lower half of the first bar graph B1 is displayed in yellow and the upper half is displayed in blue. .

In this example, the appearance of the injection molding machine is also schematically displayed in the split screen of each machine, and the background is
In order to show the current operation status, the four types of operation, the normal stop, the stop due to the abnormality, and the power off are displayed in the same corresponding color relationship as the color classification in the first bar graph B1. . That is, assuming the same as the above example, the background color is blue.

By looking at such an operation status screen, the operator or the manager can know at a glance which machine was in what operating status in the past 24 hours. The value of 24 hours is usually a fixed value, but may be variable.

By the way, in the management device 20, by clicking a specific portion (icon on the screen) of the divided screen of each unit in the above-mentioned operation status screen on the display, a general graph showing in detail the operating condition of only that unit. The screen can be displayed.

FIG. 6 shows an example of the general graph screen. In this general graph screen, 2 for each machine (here, machine 10).
The change status of the quality data for four hours, the presence / absence of an abnormality, and the presence / absence of a setting change are displayed on one screen with time as the horizontal axis. In FIG. 6, the uppermost graph is a line graph showing a change in the cumulative value of the number of shots, and a plurality of vertically arranged lines, for example, the line L1 has interruption (abnormal occurrence) of molding at around 18:00. Indicates that. The "state" of L2 is the same as the display of the operating status described above, and is defined by four types of operation, normal stop (during standby), stop due to an abnormality, and power off, for 24 hours. The state is displayed in different colors according to the time. The "condition name" of L3 is a graph showing the time when the color is changed when the molding condition is changed, that is, the condition name of each molded product is changed. In other words, this is changed when the molded product changes and is displayed in different colors, but the color itself does not have meaning, and the time when the color changes has meaning. On the other hand, the "item" of L4 is a graph that changes the color when the condition item in the molding condition is changed and displays the change with time. For example, the color is changed when the injection condition, the mold opening condition, and the like are changed, and this is also the time when the color is changed, rather than the color itself. Therefore, the colors of “condition name” and “item” are different from “state”, and four or more colors are prepared.

Further, the graph of the first stage of L5 is the "filling time" of the display item shown in the display item selection column on the lower side of FIG.
2 shows the passage of time, and the second stage similarly shows the passage of time of the "minimum cushion position". The graph in the third row shows the "holding pressure completion position", and the fourth and fifth steps show the elapsed time of the "VP switching position" and the "pre-filling position", respectively.

In the present example, the operating status of the relevant machine in the past 24 hours is further displayed on the right side of the summary graph screen.
The second bar graph B2 is displayed along with a numerical value indicating 24 hours at an operating rate of 100%. In FIG. 6, it is shown that the operating rate in the past 24 hours is 95%,
"Time display" shown in the display item selection column at the bottom of Fig. 6
The number 24, which is the base of the operation rate calculation, is displayed in the section. The numbers in the "time display" column can be changed arbitrarily. That is, the "date and time" and "time display" shown in the display item selection field can be set arbitrarily, and here, September 4, 2000 1
By setting the numerical value from 0:00 to 24 hours, as shown in the uppermost portion of FIG. 6, 24 hours from September 4, 2000 10:00 to September 5, 2000 10:00 Is displayed. If the number 12 is entered in the "time display", the operating rate for the past 12 hours based on 12 hours is displayed on the second bar graph B2. In this case, the graphs or items in the first to eighth rows in FIG. 6 are also shown for the past 12 hours. According to such a second bar graph B2, it is possible to display the operation rate from an arbitrary time and an arbitrary time.

FIG. 7 shows an example of the setting history screen. In this setting history screen, the history of setting changes is classified by machine number (here, machine number 10), changed items, set values before and after change, and change. It is displayed on one screen together with the date and time.

FIG. 8 is an example of the abnormality history screen. In this abnormality history screen, the history of abnormality occurrences is classified into 1 by machine number (here, No. 10), together with the abnormality item, occurrence date and time, and cancellation date and time.
Displayed on the screen.

As described above, the summary graph screen of FIG. 6 is linked to the operation status screen of FIG. 4, and by clicking a specific portion (icon on the screen) of each unit in the operation status screen of FIG. It is supposed to be displayed. The setting history screen of FIG. 7 and the abnormality history screen of FIG. 8 are respectively linked to the operation status screen of FIG. 4 or the summary graph screen of FIG. 6, and the operation status screen of FIG. 4 or the summary graph screen of FIG. It is designed to be displayed by clicking a specific part (icon on the screen) of.

This multi-unit management system is a system that manages the number of shots of the injection molding machine in real time and manages how many molded products are molded. Then, at least the following information is managed in this plural-device management system.

1) Mold name and number of molding shots 2) History of various abnormalities occurring in the molding machine and contents of setting changes 3) Molding conditions for molding "Remote monitoring method using communication network" (200
1 year Japanese Patent Application No. 193119).

The mold management system according to the present invention is connected to the above-mentioned plural-unit management system via a communication means, and receives at least data concerning the mold and the number of shots in each injection molding machine to manage the mold. . Before describing the mold management operation, an example of a mold to be managed according to the present invention will be described with reference to FIG.

FIG. 9 shows an example of a mold for a disk molding mold. In FIG. 9, 12 is a fixed side mold assembly that is attached to a fixed platen (not shown) by bolts (not shown). Mold assembly 1
Reference numeral 2 denotes a base plate 15, a disk plate 16 attached to the base plate 15 by bolts 17, a locate ring 23 disposed to face the fixed platen in the base plate 15, and positioning the base plate 15 with respect to the fixed platen; A sprue bush 24 is provided adjacent to the locate ring 23.

A die 28 is formed at the front end (the left end in the figure) of the sprue bush 24 so as to face the cavity C, and the die 28 is communicated with the die 28 to allow the resin injected from the injection nozzle of the injection device (not shown) to pass therethrough. Sprue 2
6 is formed.

On the other hand, reference numeral 32 denotes a movable side die assembly which is attached to a movable platen (not shown) by bolts (not shown). The mold assembly 32 is the base plate 3
5, an intermediate plate 40 attached to the base plate 35 with bolts 37, a disk plate 36 attached to the intermediate plate 40 with bolts 42, and arranged in the base plate 35 so as to face the movable platen. And a cut punch 48 which is moved forward and backward (moved to the right and left in the drawing) by the cylinder 44 and has a shape corresponding to the die 28.

Further, a concave portion for forming the cavity C is formed on the surface of the disc plate 36 facing the disc plate 16. Therefore, when a mold clamping device (not shown) is operated to move the movable platen to the fixed platen side and mold closing and mold clamping are performed, the disk plate 36 is pressed against the disk plate 16 and the cavity space C is formed.

A piston 51 formed integrally with the cut punch 48 is provided in the cylinder 44 so as to be able to move back and forth. Further, a cut punch returning spring 52 is arranged in front of the piston 51 (right side in the drawing), and the piston 51 is pushed backward by urging the cut punch returning spring 52.

Therefore, when the piston 51 is moved forward (moved to the right in the drawing) by the driving means (not shown) in the mold clamping state, the cut punch 48 is moved forward and enters the die 28. As a result, the resin in the cavity C can be perforated to remove the inner diameter of the disk substrate.

By the way, the die assemblies 12 and 32 are centered by the guide posts 54. Therefore, in the base plate 15, four guide post holes 53 (two guide post holes 53 are shown in the drawing) are concentrically formed with respect to the center of the mold assembly 12 by grinding. A guide post 54 is attached to the guide post hole 53 by press-fitting and fixing so as to protrude toward the mold assembly 32 side, and is fixed to the base plate 15 by a bolt 55.

A guide bush 57 is attached by press-fitting to the guide bush 54, and the guide post 54 can be guided by the guide bush 57. Then, when the mold is closed, the guide posts 54 are inserted into the guide holes of the guide bushes 57 via ball bearing portions (not shown), so that the mold assemblies 12, 32 can be aligned.

The disc plates 16 and 36 are provided with temperature control channels 61 and 62, respectively.
The disk plates 16 and 36 can be cooled by supplying and circulating a medium such as water, oil, or air to 1 and 62.

The mold management system according to the present invention manages the mold as described above for each part.

FIG. 1 shows a configuration in which the mold management system according to the present invention is connected to a plurality of plural management systems via a communication network such as a LAN. Here, the mold management system is the injection molding machine 10-1 to 10-10.
-Multi-unit management system consisting of n and injection molding machine 10-
It is assumed that the system is connected to a multiple unit management system consisting of 1'-10-n '. The machine number of the injection molding machine in this case is, for example, "1 machine" for 10-1 and 10-n.
Is "n-unit", 10-1 'is "(n + 1) -unit", 10
-N 'is given the number "(n + n) machine".
The mold management system is realized by a management device 1 such as a personal computer, and the management device 1 has a memory for receiving and storing data regarding the number of shots for each injection molding machine from each of the plurality of management systems. , Output means such as display, input means such as keyboard and mouse.

A mold management table as shown in FIG. 2 is created and registered in advance in the memory of the management device 1. This management table is created for each mold that is operating in the injection molding machine. In order to create a management table, a unique management number is assigned in advance to each of the plurality of parts that make up the mold. The control numbers of these respective parts are different even if they are the same type of mold.

Speaking of the disk molding die described with reference to FIG. 9, the base plates 15 and 35, the disc plate 1
6, 36, locate ring 23, sprue bush 2
4, intermediate plate 40, cylinder 44, cut punch 4
8, management numbers are given in advance to the piston 51, the cut punch return spring 52, the guide post 54, the guide bush 57, and the like.

In FIG. 2, the management table shows a part name, its management number, the total number of shots used for molding up to the present time, for each part constituting the mold of the injection molding machine in operation. It shows the correspondence relationship between the number of life shots obtained by converting the life of a component calculated in advance into the number of shots, and the number of maintenance shots for which maintenance should be performed on the component. In FIG. 2, “10” is input as the machine number of the injection molding machine, “disk molding die” is input as the die name, and “base plate”, “disk plate”, “locating ring”, and “sprue bush” are input as the part names. ], “Intermediate plate”, “Cylinder”,
Other (not shown) is entered. Then, in addition to the management number, the number of life shots, and the number of maintenance shots being entered for each column, when the part is replaced, the replacement date is also entered. This exchange date is cumulatively registered, and all the registered information is displayed so that the number of exchanges can be known.

This management table is specified by designating the machine number of the injection molding machine on the display of the management device 1.
It is possible to display the mold management table of the desired injection molding machine, and the contents of each column can be changed by the input means, but the total number of shots can be changed by the shot number data sent from the multiple unit management system. Updated with each shot.

The management apparatus 1 collectively manages the management tables of a large number of molds in a large number of injection molding machines managed by two plural-piece management systems, and shots the total shot number of each part in each management table. It is updated every time and when the total number of shots of a certain component reaches the number of maintenance shots set for this certain component, an alarm is displayed on the display. The form of the alarm display is such that, for example, a management table including the relevant parts is forcibly displayed, and the item of the total number of shots in the column of the relevant parts in the management table is displayed in red and blinks. However, this display form is arbitrary. When such a display is made, the operator can confirm the blinking part name of the mold according to the display contents and know that the part needs maintenance.

By the way, the management apparatus 1 further stores in the memory a spare parts table in which all the spare parts prepared as spare parts are registered, in addition to the management table for the molds in operation. This spare parts table is exactly the same as the management table, except that the mold parts that are not in operation are registered. In other words, even in this spare parts table,
The name of each spare part, its control number, the total number of shots used for molding up to the present time, the number of life shots obtained by converting the pre-calculated life of each part into shots, and further maintenance Indicates the correspondence between the number of maintenance shots to be performed and the replacement time. There is an item for registering the total number of shots in the spare parts table, because the spare parts may be temporarily used in a mold and then placed in a standby state as spare parts again. That is, the number of shots during this temporary use is held as the total number of shots. Further, when a completely new part is prepared and replaced instead of the part managed in the spare parts table, the management number, the life shot number, and the maintenance shot number are input to the management table. On the other hand, if a completely new part is placed in standby as a spare part,
A new item for this new part is registered in the spare parts table and necessary data is input.

In both the management table and the spare parts table, the management number information indicating the management number includes name information indicating the name, total shot number information indicating the total shot number, and life shot number information indicating the life shot number. The warning shot number information indicating the number of warning shots, the maintenance shot number information indicating the number of maintenance shots, and the replacement time information indicating the replacement time are attached. Accordingly, the management device 1 refers to the spare part table when the part in the mold under management is replaced with the part registered in the spare part table and the management number of the replaced part is input. Name information associated with the input management number in the spare parts table, including name information, total shot number information, life shot number information, maintenance shot number information, and replacement time information in the column of replaced parts in the management table. The total shot number information, the life shot number information, the maintenance shot number information, and the replacement time information are automatically updated.

For example, in FIG. 2, assuming that 3 locate rings are exchanged, name information, total shot number information, life shot number information, and maintenance shots of the locate ring columns managed in the management table until then. The number information and the replacement time information are moved to the spare parts table, and instead, the name information, the total shot number information, the life shot number information, the maintenance shot number information, and the replacement time information of the locate ring column registered in the spare parts table. And are transferred to the management table. As a result, for example, if the replaced locate ring has been used for a certain number of shots S1 and the molding is restarted after the replacement, the total number of shots of the locate ring is added to a certain shot number S1. The calculated value will be updated as the total number of shots.

According to such a configuration, no matter which part is replaced in which mold at any time, the total number of shots relating to the replaced part can be surely grasped, and the maintenance time and the life can be accurately determined by the operator. Can be informed.

Incidentally, in the management apparatus 1, in addition to the display of the management table as shown in FIG. 2 on the display, the history of how the specific mold has been used up to now, that is, by the setting by the input means, that is, It is possible to display a history such as which part was replaced when. The management apparatus 1 also receives the abnormality history of a specific mold, that is, the history of what kind of abnormality has occurred in which component so far from the multiple-unit management system by receiving the data for the abnormality history screen described in FIG. This can also be used for display.

As is apparent from the above description, the mold management system according to the present invention can realize the following management.

1) The shot number data of the mold for each injection molding machine is received from each plural-unit management system.

2) Within the mold management system, the mold is managed for each part, and the number-of-shots data of item 1) is added for each part. With this mechanism, the number of molding shots is managed for each part of the mold.

3) The mold management system can be set in advance for preventive maintenance, that is, the number of maintenance shots and the number of life shots can be set for each part.
The actual value and the set value are compared in real time, and when the actual value reaches the set value, alarm processing is performed. In the alarm process, in addition to the example described above, a picture of the mold is displayed on the display screen in 3D
It is also possible to display the image in an image) form or a 2D form, change the color of the corresponding part, or send a mail to the operator. This alarm process can be arbitrarily set according to the customer's request, so any display form may be used.

4) Even if a part is moved from one mold to another, by inputting the management number of the part, the shot number data up to now can be managed without disappearing.

5) The mold management system allows the operator to display the history of any mold,
You can keep past maintenance records.

6) From the mold management system to the management system for a plurality of injection molding machines, the abnormality history data relating to a specific mold can be called by the communication means to display the abnormality history.

7) The mold management system shown in FIG. 1 is arranged at the manufacturer of the injection molding machine or its management center,
