It is wrapped. Also, an actual measurement value storage unit 1
In FIG. 8, a cushion amount, which is an item closely related to the quality of a molded product, other than the above-mentioned operation condition items, is measured and calculated for each shot and stored. In addition,
In FIG. 7, SS indicates input information from the sensor group. Reference numeral 30 denotes a condition value calculation microcomputer communicably connected to the machine control microcomputer 4, which is a so-called expert for inferring and calculating the optimum molding operation condition value based on various molding operation empirical rules learned and stored in advance. A system is constructed, and the condition value calculation microcomputer 30 includes a condition value calculation processing unit 32 and an initial operation condition calculation table 33. Reference numeral 35 denotes a key input device for the condition value calculation microcomputer 30, and 36 denotes a color C for the condition value calculation microcomputer 30.
This is a display device including an RT display.

The condition value calculation processing section 32 refers to the contents of the initial operation condition calculation table 33 when an operator inputs an initial condition when a mold is replaced and a new product is formed, and the above-mentioned conditions are used. The set value of the molding operation condition item is automatically calculated, and this can be transferred to the molding condition storage unit 16 of the machine control microcomputer 4. That is, by operating the key input device 35 to set the condition value calculating microcomputer 30 to the input setting mode of the initial condition,
An input setting mode screen such as that shown in Table 1 is displayed on the display device 36, and the operator looks at this display screen and interactively interacts with the resin material data and the mold-related data (cavity, sprue, runner) as initial conditions. , Data on the gate and the number of products) are input using a cursor movement key, a numerical key, a function key, a confirmation key and the like.

[Table 1] In the initial operation condition calculation table 33, a conversion table, an arithmetic expression, and the like for inferring and calculating the set values of the respective molding operation condition items from the resin material data and the data relating to the mold are stored as case studies in advance and stored. The condition value calculation processing unit 32 compares the initial condition data input by the operator with the contents of the initial operation condition calculation table 33 and sequentially calculates a large number of operation condition values as described above. Has become. The calculated operating condition value is
When the operator confirms this and presses the return key, the calculated operating condition values are displayed on the display device 36, for example, in the form shown in FIG. The data is transferred and stored in the storage unit 16.

Next, the operation of the conventional example based on the above configuration will be described. First, when a mold is replaced and a new product is formed, an operator sets the input of the display device 36 as shown in Table 1. The user views the mode screen and interactively inputs the initial condition values to the condition value calculating microcomputer 30 by the key input device 35 in an interactive manner. As the initial condition value, as described above, the resin material data and the data relating to the mold are exemplified. As the resin material data, an operator inputs a resin name (stored as a code in Table 1), a product name, a grade, and a manufacturer name. The mold data includes cavities, sprues,
Data on runners and gates are listed, and data on cavities include shape type, maximum thickness, minimum thickness, volume, number (number of pieces), and fluidity (flow distance L from the gate to the end of the cavity and average thickness between them). (L / T value that determines the thickness) is input, and as the gate data, the shape type, the number of gates, and the gate cross-sectional area are input, and as the runner data, the system type, shape type, runner length, The area is input, and as the data relating to the sprue, the method type, the length, and the sprue diameter are input. Although the product weight data is not set as an initial input item, it is obvious to those skilled in the art that it can be calculated as needed based on the resin material data and the mold-related data.

As described above, the initial condition values (resin material data,
When the data relating to the mold is input, the condition value calculation processing unit 32 of the condition value calculation microcomputer 30 refers to the contents of the initial operation condition calculation table 33 based on the input data, and automatically executes the machine operation as described above. A number of operation condition values (heater temperature, charge condition, primary injection condition, pressure holding condition, mold opening / closing condition, etc.) necessary for the operation are calculated. This calculation result is displayed on the display device 36 as shown in FIG.
The data is transferred to and stored in the molding condition storage unit 16 of the machine control microcomputer 4 by an instruction of an operator or automatic data transmission.

[0010]

When calculating the initial operating conditions, it is necessary to prepare a large amount of mold data (17 points in the conventional example) in advance. Taking advantage of the large point, there is a tendency to integrate a plurality of parts, and the shape, thickness, and gate are complicated, and it has become difficult to show the shape characteristics with these data. Therefore, it is difficult to estimate the optimal injection condition. In addition, there are various raw material manufacturers, grades, and trade names for resin codes, and it was impossible to completely prepare a database of these physical properties. Further, the physical properties of the resin also change variously depending on the temperature and pressure. In injection molding, the temperature of the molten resin flowing in the mold has a great effect on cooling and flow, but the screw design, cylinder set temperature,
It also changes depending on screw speed, back pressure, etc. Therefore, in order to calculate all of these effects, it is necessary to measure the physical properties of all resin grades in a wide range of temperature and pressure, and it is not easy to create a database for these. For this reason, it was difficult to calculate the initial operation conditions for injection and plasticization which are close to the optimum conditions, while preparing the data of the resin mold.

In recent injection molding machines, it is necessary to input all digital values using a color CRT display device and a key input device due to the development of microcomputer control. However, since the conventional mold opening / closing position and the like are adjustment of a limit switch such as a proximity switch or the like, a test shot is repeated, and the operation is determined to a suitable position by a measure. On the other hand, the control device of the microcomputer has to determine the numerical values of the setting items which can be appropriately input and input the numerical values, which is troublesome for the operator. Therefore, there is a device that calculates the initial operating conditions separately from the control device of the present device, because it takes time and effort to input and set. Therefore, it is desired that the control device of the present device calculates the initial operating conditions and can operate immediately. I was The present invention has been proposed to solve the above-mentioned conventional problems.

[0012]

SUMMARY OF THE INVENTION Therefore, the present invention provides a color graphic display device such as a color CRT for displaying a data group, and a condition value calculation processing section for calculating initial operation conditions based on data of an initial operation condition calculation table. a data display method of an injection molding machine having a display settings are arranged on the operation process chart form on the screen, after entering the initial input item, running enter condition calculating other settings Fast entry screen to automatically set the In addition to displaying the initial input items, automatic setting items, and execution values, a batch input screen that can change the number of setting steps for injection, plasticization conditions, and mold opening / closing conditions can be displayed as a sub-screen. This is a means for solving the problem. Further, in the present invention, the initial input items are a mold closing start position, a protruding advance position, a mold thickness, a resin name, a molded product wall thickness, and a molded product weight. In addition, the execution value of the control operation is displayed in a color-coded manner with the set value, and a frame is displayed around the set value on the simple input screen, and the initial input item and the automatically set item are displayed. The colors are color-coded to make it easier for the operator to identify, and this is used as a means for solving the problem. The present invention is shown by displaying the cursor to select the set values of the operating conditions at that position strike
Both those the cursor by pressing the tab key is so as to sequentially move displaying the first <br/> period input field,
This is a means for solving the problem.

[0013]

According to the present invention, on the display screen of the operating conditions, the mold closing start position, the protruding advance position, the mold thickness, the resin name which is the basic condition of the resin mold data, the molded product wall thickness, the molding, which cannot be uniquely estimated from the mold. The initial input items of the product weight are color-coded to notify the operator, and after inputting the items, the conditions are calculated and the initial operation conditions are automatically set assuming an average case. Then, since the execution values are displayed on the screen, the operator mainly changes the injection plasticization conditions and obtains the optimum conditions while checking the execution values so as to be suitable for actual molding. In addition, since the resin mold data includes only three points, namely, the resin name, the molded product wall thickness, and the molded product weight, preparation of input data is facilitated. Further, since the condition calculation and the execution value confirmation can be corrected on the same screen, the operation can be performed efficiently. In addition, since it is assumed that the modification is changed, the initial condition can be an average condition.
General names such as S and PS, and mold data are also only molded products, wall thicknesses and molded product weights, and other data such as temperature conditions are calculated assuming general conditions.

It is displayed in S3 0, LS3 1. On the other hand, the code of the limit switch of the conventional injection molding machine in which the position is set by the proximity switch or the limit switch is used as it is. This is because it is easier to use the display method that the operator is used to as it is. The speed and pressure are abbreviations in English, for example, VCH of A mark 120a.
(Velocity Clamp High Spea
As in d), a code is added. Further, the numeral of the setting value is green, the color of the frame surrounding the setting value is red-purple for the initial input items, and white for the others. The graphics such as A mark for molds such as mold closing, mold opening, protrusion, wall thickness and weight etc. are unified in white, and the B mark for injection and plasticization and the screw graphic shown in the lower right are unified in blue. I have.

The numbers of the following execution values are yellow, the color of the frame surrounding the numbers is white, and the name and unit are displayed on the side of the frame. Note that the initial input items and the automatic setting items (condition calculation items) other than the following execution values are displayed with a white frame and green numbers. (1) Mold position (position of movable platen) (2) Cushion (cushion amount of screw) (3) Mold closing (time required for mold closing) (4) Mold opening (time required for mold opening) (5) Projection amount (Position of protruding plate) (6) Cycle (cycle time) (7) Injection (injection time) (8) Plasticization (plasticization time) (9) Rotation speed (screw rotation speed) Items, execution values, automatic setting items and the like are easily identified.

Next, the condition calculation method will be described with reference to the flowchart shown in FIG. (1) The following point b is input as an initial input item. 120e ...

LS30 (projection advance position) 120g ... mold thickness (die thickness) 120h ... wall thickness (molded product thickness H) 120i ... weight (molded product weight W) 120j ... Resin name code (numerical value) In the items of 120e to 120i, numbers are input using the tab key 119g and the numeric keypad 119c. Each time the tab key 119g is pressed, the cursor sequentially moves to items 120e to 120k. Tab key 119h is tab key 1
Moves in the opposite direction to 19g. Further, the resin name code 120j

When you press the DOWN) key 119e, between resin name code 120j press the same key corresponds to the scroll U P / DOWN number is increased or decreased, 1 ... ABS, 2 ... ACS , 3 ... in alphabetical order in the order of AS and numbers Corresponding resin name 1
20m is displayed. When the desired resin name 120m is displayed, pressing the key is stopped, and the displayed resin name 120m is selected. (2) When the initial input items are input as described above, the operator moves the cursor with the tab key 119g to the condition calculation 120k in FIG. 3 and inputs a code “1” meaning execution of “condition calculation”.

(3) Next, the condition calculation processes (a), (b), (c), (d) and (e) shown in the flowchart of FIG. 4 are performed. (A) Mold opening / closing condition ... The condition value calculation processing section 132 calls up the experience value of the mold opening / closing operation condition for each model stored in the initial operation condition calculation table 133. For example, as the initial operation condition, the mold closing speed VCH is set to the medium speed “50”.
% ", The mold clamping pressure PCH is" 50% ", and the protrusion and retreat position LS
3 1 is a most retreated position "0.0mm", low speed switching position LS2 and LS4 of mold opening and closing, the characteristic values determined from experiments of each model that can be decelerated sufficiently predetermined low speed against the mold closing rate, initial It is stored in the operating condition calculation table 133.

(B) Screw Position Calculation The screw weighing completion position LS8 is calculated by the following equation.

(Equation 1) W: Molded product weight (initial input item) ρ: Resin melt density A: Screw cross-section Resin melt density ρ is obtained from the resin constant table (stored in the initial operation condition calculation table 133) by inputting the resin name. Is read. LS7 is an injection low speed switching point, which is calculated based on a ratio α stored in the same table 133 as an empirical value with respect to the metering completion position. Further, an empirical value β stored in the table 133 is set for the pressure holding switching position LS6.

(C) The resin constant table contains the nozzle, cylinder set temperature, melt density ρ, temperature conductivity a, and the nozzle corresponding to each resin of resin code and resin name (for example, ABS, AS, PA6, PA66). Melt resin temperature θm at the time of plasticization at temperature, commonly used mold temperature θw, removal temperature θcm of molded product (generally becomes the thermal deformation temperature of resin), injection speed, filling pressure, and holding pressure , Screw speed,
The experience value of the general use condition of the back pressure is stored.

(D) The injection speed, filling pressure, holding pressure, screw rotation speed, and back pressure are read as table value data corresponding to the resin. (e) The cooling time t _C is determined by the parameters a,
θm, θw, and θcm are read, and are calculated by the following equation using the molded product thickness H, which is an initial input item.

(Equation 2) H: molded product thickness a: temperature conductivity θm: molten resin temperature θw: mold temperature θcm: unloading temperature

(4) The calculated initial operating conditions are automatically set and displayed on the simplified input screen shown in FIG. (5) At the same time, the batch input screen shown in FIG.
The same conditions are displayed. (6) The same conditions are stored in the molding condition storage unit 16.

On the basis of the initial operation conditions automatically set as described above, the operator mainly changes the injection plasticization conditions so as to be suitable for actual molding while checking the execution values by trial shots. In addition, the simple input screen shows the speed of the mold opening / closing, injection, screw rotation, and the number of pressure stages that can correspond to almost general molding.However, in the case of a complex molded product or a special mold, the speed pressure In some cases, more complicated control is required. At this time, there is a sub-screen display 120u at the right end of the simplified input screen shown in FIG. 3, which shows the contents of A to F of the sub-screen selection key 119b. When "B" of the screen selection key 119b is pressed, the collective input screen shown in FIG.

The display screen displays the set values of each operation in a table format. In the columns of the table, the number of stages of speed and pressure of mold opening / closing, injection, and plasticization is increased so that complicated molding is possible. However, only the same setting values as those on the simple input screen are displayed, and the other speed and pressure stages are blank. For example, the set values “200.
0 "and" 50.0 ". Here, the number of levels LS2A, LS2B, and LS2C added to the simple input screen are blank. Since the mold closing speed from LS1 to LS2 is also constant at 50%, the steps of the speed setting values below LS2A, LS2B and LS2C are blank. The set value is displayed in green, and the execution value is displayed in yellow. The execution values are the same as those in the simple input screen, and the following nine items are further added. (1) Screw position (2) Resin pressure (3) Mold clamping force (4) Nozzle and cylinder temperature
It can be changed by the ten keys 119c. At this time, the changed set value is changed to the same set value displayed on the simple input screen and stored in the molding condition storage unit 16 (operations (5) and (6) in the flowchart shown in FIG. 4).

There are cases where it is desired to increase the number of speed pressure stages as described below. Since molding defects such as flow marks occur due to changes in resin flow at the multipoint gates and pin ribs,
The pressure is changed in multiple stages. In order to make the molten resin temperature uniform, the screw rotation speed and back pressure are program-controlled in multiple stages. When using a three-piece mold, reduce the speed before the movable side of the mold contacts the intermediate plate, and then increase the speed again to reduce the speed before the movable side of the mold and the intermediate plate contact the fixed side of the mold. I want to make the mold opening / closing speed more multi-stage by the structure of the mold. In order to cope with this, the setting value 120 of the condition number of steps shown in FIG.
When the cursor is moved to n and a code is inputted from the ten key 119c, the number of speed and pressure conditions can be changed to two as shown in Table 2.

[Table 2]

When "1" is input in the batch input screen with the condition number of steps 120n, the display screen shown in FIG. 6 is displayed. As for the injection condition, “0.0” is displayed at the added number of stages as in the injection condition table 120t, and the operator can input a necessary set value from the ten keys 119c. The mold opening / closing and plasticization are carried out in a mold closing condition table 120p, a mold opening condition table 120q, a rotation speed condition table 120r, and a back pressure condition table 120p.
As shown in s, the upper limit and lower limit of the position set value are determined on the simple input screen, so that the position is equally divided and automatically assigned, and the interval is automatically set as the same speed and pressure. For example, in the mold closing condition table 120p, LS1 "200"
And 150mm between LS2 "50" and 4
/4=27.5, LS2A = 162.5 mm, LS2B
= 125.0 mm, LS2C = 87.5 mm, LS
The speed between 2A and LS2C is automatically set to the same “50%”. Further, the condition values displayed and set on the batch input screen in this way are stored in the molding condition storage unit 16. In this embodiment, the number of stages is changed in two types. However, three or more types can be changed by increasing the code number and creating an intermediate pattern.

On the other hand, in the embodiment, the mold thickness is set as the initial input. However, in the mold set mode (the movement of the mold plate becomes slow in all areas in the mold opening / closing operation mode when the mold is mounted), the mold is closed with the mold interposed therebetween. At that time, a method may be adopted in which the position of the mold plate is read by a sensor using a trigger signal such as an operator turning on a switch and the mold thickness is set. In order to select a set value, the cursor is moved to the set value with a cursor key. However, a method in which a film-like touch key is pasted on a color CRT display and the set value is directly touched by hand is selected. , The operability is further improved.

[0028]

As described in detail above, according to the present invention, the initial operation conditions of mold opening / closing, injection, and plasticization are automatically set with a simple input, so that the input operation of the operator is simplified. In addition, since it is only necessary to change a part that requires a condition change while checking the execution value, it is possible to standardize molding conditions. Furthermore, since condition calculation, setting value change, and execution value confirmation can be performed on the same screen, the operation is simplified, and the time required for conventional screen switching and condition transfer is not required.
Operation efficiency can be improved. Further, the setting values, execution values, and initial input items are easily identified by the operator by color coding of frames and numbers, or the cursor is sequentially moved by pressing the tab key for the initial input items, so that the input operation is easy.
