The toggle mechanism 20 is a so-called involute 5-node double toggle mechanism which is vertically symmetrical. In addition, the toggle mechanism 20 may be an outer rolled toggle, a single toggle, or a 4-node toggle.
合模馬達26為藉由驅動軸25使肘節機構20作動之驅動部。在合模馬達26與驅動軸25之間設置有將合模馬達26的旋轉運動轉換為直線運動並傳遞至驅動軸25之作為運動轉換部的滾珠螺桿機構。 The mold clamping motor 26 is a drive unit that operates the toggle mechanism 20 by the drive shaft 25. Between the mold clamping motor 26 and the drive shaft 25, a ball screw mechanism as a motion conversion portion that converts the rotational motion of the mold clamping motor 26 into a linear motion and transmits it to the drive shaft 25 is provided.
藉由十字頭21與驅動軸25一同進退，從而使肘節機構20作動。若可動壓板13前進，則進行閉模。而且，產生由合模馬達26產生的推動力乘以肘節倍率之合模力，並藉由合模力進行合模。肘節倍率係指將肘節機構20的輸入設為1時的肘節機構20的輸出。若可動壓板13後退，則進行開模。 The toggle mechanism 20 is actuated by the crosshead 21 advancing and retracting together with the drive shaft 25. When the movable platen 13 advances, the mold is closed. Further, the urging force generated by the mold clamping motor 26 is multiplied by the clamping force of the toggle ratio, and the mold clamping is performed by the mold clamping force. The toggle magnification refers to the output of the toggle mechanism 20 when the input of the toggle mechanism 20 is set to 1. If the movable platen 13 is retracted, the mold opening is performed.
合模馬達26具有編碼器26a。編碼器26a檢測合模馬達26的輸出軸的旋轉角，並將表示該旋轉角之訊號輸出至控制裝置80。 The mold clamping motor 26 has an encoder 26a. The encoder 26a detects the rotation angle of the output shaft of the mold clamping motor 26, and outputs a signal indicating the rotation angle to the control device 80.

An external thread 41 is formed at a rear end portion of the tie rod 16 inserted through the through hole of the rear platen 15. The internal thread 42 screwed to the external thread 41 is rotatably held by the rear platen 15. The die thickness motor 43 is fixed to the rear platen 15, and the rotational motion of the die thickness motor 43 is transmitted to the respective internal threads 42 via the timing belt 45 or the like.
藉由各內螺紋42的旋轉，能夠調整後壓板15相對於 各繫桿16之位置，且能夠調整後壓板15相對於固定壓板12之位置。由外螺紋41、內螺紋42、模厚馬達43等構成模厚調整機構40。另外，作為將模厚馬達43的旋轉運動傳遞至各內螺紋42之傳遞構件，可使用齒輪來代替同步帶45。 By rotating the internal threads 42, the rear platen 15 can be adjusted relative to The position of each tie rod 16 and the position of the rear pressure plate 15 relative to the fixed pressure plate 12 can be adjusted. The mold thickness adjustment mechanism 40 is constituted by the external thread 41, the internal thread 42, the mold thickness motor 43, and the like. Further, as a transmission member that transmits the rotational motion of the mold thickness motor 43 to each internal thread 42, a gear can be used instead of the timing belt 45.
模厚馬達43具有編碼器43a。編碼器43a藉由檢測模厚馬達43的輸出軸的旋轉角來檢測後壓板15相對於固定壓板12之位置，並將表示該位置之訊號輸出至控制裝置80。 The mold thickness motor 43 has an encoder 43a. The encoder 43a detects the position of the rear platen 15 with respect to the fixed platen 12 by detecting the rotation angle of the output shaft of the die thickness motor 43, and outputs a signal indicating the position to the control device 80.
另外，模厚調整機構40的構成並不限定於上述構成。例如外螺紋41可以形成於各繫桿16的前端部，內螺紋42可以旋轉自如地保持在固定壓板12上。藉由各內螺紋42旋轉，能夠調整各繫桿16相對於固定壓板12之位置，且能夠調整後壓板15相對於固定壓板12之位置。 Further, the configuration of the mold thickness adjusting mechanism 40 is not limited to the above configuration. For example, the external thread 41 may be formed at the front end portion of each tie rod 16, and the internal thread 42 may be rotatably held on the fixed platen 12. By rotating the internal threads 42, the position of each tie rod 16 with respect to the fixed pressure plate 12 can be adjusted, and the position of the rear pressure plate 15 with respect to the fixed pressure plate 12 can be adjusted.
在開模結束的狀態(參閱第1圖)下，控制裝置80對合模馬達26進行控制而使可動壓板13前進。由此，可動模33的框狀部33b被固定模32按壓，可動模33的彈簧部33c收縮。可動模33的模具主體部33a前進至規定位置，在可動模33與固定模32之間形成模穴空間34。 In a state where the mold opening is completed (see Fig. 1), the control device 80 controls the mold clamping motor 26 to advance the movable platen 13. Thereby, the frame-like portion 33b of the movable mold 33 is pressed by the fixed mold 32, and the spring portion 33c of the movable mold 33 is contracted. The mold main body portion 33a of the movable mold 33 is advanced to a predetermined position, and a cavity space 34 is formed between the movable mold 33 and the fixed mold 32.
接著，控制裝置80對射出裝置50進行控制而使液態的成形材料填充於模穴空間34內。在填充成形材料過程中，控制裝置80可控制合模馬達26以防止可動壓板13進退。 Next, the control device 80 controls the injection device 50 to fill the liquid molding material in the cavity space 34. During filling of the forming material, the control device 80 can control the mold clamping motor 26 to prevent the movable platen 13 from advancing and retracting.
其後，控制裝置80對合模馬達26進行控制而使可動 壓板13進一步前進。彈簧部33c進一步收縮，模穴空間34變小，模穴空間34內的成形材料被壓縮。能夠獲得成形品變薄、提高複製性、減少收縮等效果。 Thereafter, the control device 80 controls the mold clamping motor 26 to be movable. The platen 13 is advanced further. The spring portion 33c is further contracted, the cavity space 34 is made smaller, and the molding material in the cavity space 34 is compressed. It is possible to obtain effects such as thinning of the molded article, improvement of reproducibility, and reduction of shrinkage.
另外，在本實施形態中，模穴空間34內的成形材料的壓縮在成形材料的填充結束後開始，但亦可以在填充成形材料的中途開始。可動壓板13可在填充成形材料時進退。 Further, in the present embodiment, the compression of the molding material in the cavity space 34 is started after the filling of the molding material is completed, but it may be started in the middle of filling the molding material. The movable platen 13 can advance and retreat when filling the molding material.
模穴空間34內的成形材料壓縮後，控制裝置80可以使可動壓板後退，使合模力降低，且使作用於模穴空間34內的成形材料之壓力降低。 After the molding material in the cavity space 34 is compressed, the control device 80 can retract the movable platen, lower the mold clamping force, and lower the pressure of the molding material acting in the cavity space 34.
然而，控制裝置80對合模馬達26進行反饋控制，以使控制量的設定值與實際值的偏差成為零。作為控制量可以舉出例如合模力、可動壓板13的位置等。可動壓板13的位置可以表示為例如自可動壓板13的基準位置起的距離，或者可動模33的模具主體部33a與固定模32之間的間隔等。 However, the control device 80 performs feedback control of the mold clamping motor 26 so that the deviation between the set value of the control amount and the actual value becomes zero. The control amount includes, for example, a mold clamping force, a position of the movable platen 13, and the like. The position of the movable platen 13 can be expressed, for example, as a distance from the reference position of the movable platen 13, or an interval between the mold main body portion 33a of the movable mold 33 and the fixed mold 32, and the like.
合模力的實際值使用合模力檢測器18來檢測。可動壓板13的位置使用編碼器26a或者距離感測器來檢測。作為距離感測器，例如可以舉出檢測可動模33的模具主體部33a與固定模32之間的間隔之間隙感測器等。 The actual value of the mold clamping force is detected using the mold clamping force detector 18. The position of the movable platen 13 is detected using an encoder 26a or a distance sensor. As the distance sensor, for example, a gap sensor that detects a gap between the mold main body portion 33a of the movable mold 33 and the fixed mold 32 can be cited.
可動壓板13的位置係與合模力相對應者。若控制裝置80使可動壓板13後退，則合模力降低。 The position of the movable platen 13 corresponds to the mold clamping force. When the control device 80 moves the movable platen 13 backward, the mold clamping force is lowered.
控制裝置80使可動壓板13後退並使合模力降低時，可動壓板13與後壓板15之間的間隔變窄，因此第1肘節 桿22與肘節臂24所成角θ(以下稱為連桿角度θ)變小，且肘節倍率變小。 When the control device 80 retracts the movable platen 13 and lowers the mold clamping force, the interval between the movable platen 13 and the rear platen 15 is narrowed, so the first toggle The angle θ between the rod 22 and the toggle arm 24 (hereinafter referred to as the link angle θ) becomes small, and the toggle magnification becomes small.
然而，合模力相同時，若肘節倍率變小，則合模馬達26的負載(例如轉矩)變大。並且，肘節倍率相同時，若合模力變小，則合模馬達26的負載變小。 However, when the clamping force is the same, if the toggle magnification is small, the load (for example, torque) of the mold clamping motor 26 becomes large. Further, when the toggle ratio is the same, if the mold clamping force is small, the load of the mold clamping motor 26 becomes small.
控制裝置80使可動壓板13後退並使合模力降低時，隨著肘節倍率變小，合模馬達26的負載逐漸變大，若超過峰值，則逐漸變小。合模力與合模馬達26的負載不成比例，因此合模馬達26的負載有時會大於預想值。 When the control device 80 retracts the movable platen 13 and lowers the mold clamping force, the load of the mold clamping motor 26 gradually increases as the toggle ratio becomes smaller, and becomes smaller as it exceeds the peak value. The mold clamping force is not proportional to the load of the mold clamping motor 26, so the load of the mold clamping motor 26 may sometimes be larger than the expected value.
控制裝置80計算設定條件中之合模馬達26的負載，並依據該負載判斷設定條件是否適合。能夠在實際驅動合模馬達26之前判斷設定條件是否適合，且能夠避免合模馬達26的過負載引起之停止。並且，與控制裝置80分開設置資訊處理裝置時，能夠有助於購買射出成形機時的合模馬達26的選定。 The control device 80 calculates the load of the mold clamping motor 26 in the set condition, and determines whether the set condition is suitable based on the load. It is possible to judge whether or not the setting condition is appropriate before actually driving the mold clamping motor 26, and it is possible to avoid the stop caused by the overload of the mold clamping motor 26. Further, when the information processing device is provided separately from the control device 80, it is possible to contribute to the selection of the mold clamping motor 26 when the injection molding machine is purchased.
控制裝置80將控制量與合模馬達26的負載之間的關係以表或公式等形態存儲於存儲部81。負載與電流之間具有對應關係，因此負載可以由電流表示。 The control device 80 stores the relationship between the control amount and the load of the mold clamping motor 26 in the storage unit 81 in the form of a table or a formula. There is a correspondence between the load and the current, so the load can be represented by current.
肘節倍率依據後壓板15相對於固定壓板12之位置發生變化。因此，控制裝置80可以針對後壓板15相對於固定壓板12之各位置，將上述關係存儲於存儲部81。 The toggle magnification varies depending on the position of the rear platen 15 relative to the fixed platen 12. Therefore, the control device 80 can store the above relationship in the storage unit 81 with respect to each position of the rear platen 15 with respect to the fixed platen 12.
控制裝置80依據存儲於存儲部81之上述關係和設定條件，計算設定條件中之合模馬達26的負載。 The control device 80 calculates the load of the mold clamping motor 26 in the setting condition based on the above relationship and setting conditions stored in the storage unit 81.
控制裝置80可以藉由將設定條件中之負載和容許負 載進行比較來判斷設定條件是否適合。當設定條件中之負載超過容許負載時判斷為設定條件不適合，當設定條件中之負載為容許負載以下時判斷為設定條件適合。容許負載被預先設定，並存儲於存儲部81。 The control device 80 can pass the load and allow negative in the set conditions Compare and judge whether the setting conditions are suitable. When the load in the setting condition exceeds the allowable load, it is determined that the setting condition is not suitable, and when the load in the setting condition is equal to or less than the allowable load, it is determined that the setting condition is appropriate. The allowable load is set in advance and stored in the storage unit 81.
另外，控制裝置80可以將設定條件中之負載除以最大負載之值與容許負載除以最大負載之值進行比較。最大負載為來自逆變器的輸出電流為最大值時的合模馬達26的負載。 In addition, the control device 80 can compare the load in the set condition by the value of the maximum load with the value of the allowable load divided by the maximum load. The maximum load is the load of the mold clamping motor 26 when the output current from the inverter is at the maximum value.
設定條件中之負載可以用有效值表示，容許負載可以是額定值。合模馬達26的負載週期性變化，並用時間函數f(t)表示。其有效值為在週期T內對函數f(t)的平方值進行積分，將該積分值F除以週期T而得到之值的平方根。週期T為成形週期時間。額定值為連續不斷地使用合模馬達26時合模馬達26的溫度成為容許溫度以下之上限值。將有效值與額定值進行比較，從而能夠避免週期運行時由異常檢測引起之停止。 The load in the set condition can be expressed as a valid value, and the allowable load can be a rated value. The load of the mold clamping motor 26 changes periodically and is represented by a time function f(t). The effective value is the square root of the value obtained by integrating the square value of the function f(t) in the period T and dividing the integral value F by the period T. The period T is the forming cycle time. When the clamp motor 26 is continuously used, the temperature of the mold clamping motor 26 becomes the upper limit or lower of the allowable temperature. The effective value is compared with the rated value to avoid the stop caused by the abnormality detection during the cyclic operation.
另外，本實施形態的額定值為連續不斷地使用合模馬達26時合模馬達26的溫度成為容許溫度以下之上限值，但亦可以是逆變器的溫度成為容許溫度以下之上限值。 Further, the rated value of the present embodiment is that the temperature of the mold clamping motor 26 is equal to or lower than the allowable temperature when the mold clamping motor 26 is continuously used. However, the temperature of the inverter may be equal to or lower than the allowable temperature. value.
有效值可以作為對於額定值之比例來計算，該比例亦可以用百分率表示。有效值與額定值之間的關係容易理解，且易於比較。 The effective value can be calculated as a ratio to the rated value, which can also be expressed as a percentage. The relationship between the effective value and the rated value is easy to understand and easy to compare.
設定條件(例如合模力的設定值)可以在1個成形週期中階段性地設定。由此，函數f(t)在1個成形週期中 階段性地變化。 The setting conditions (for example, the set value of the mold clamping force) can be set stepwise in one molding cycle. Thus, the function f(t) is in one forming cycle Change in stages.
控制裝置80計算各階段的設定帶給有效值之影響度。第k(k為1以上的自然數)階段的影響度例如可計算在第k階段的保持時間內對將函數f(t)的平方值進行積分之值Fk與上述積分值F之比(Fk/F)。可知第幾階段的設定的影響度較大。 The control device 80 calculates the degree of influence of the setting of each stage on the effective value. The influence degree of the kth (k is a natural number of 1 or more) stage can be calculated, for example, by the ratio of the value Fk integrating the square value of the function f(t) to the above-described integral value F in the holding time of the kth stage (Fk /F). It can be seen that the influence of the setting of the first stage is large.
第k階段的影響度可計算為上述比(Fk/F)乘以有效值之值。在此所用之有效值可以是相對額定值之比例。第k階段的影響度與額定值之間的關係容易理解，且易於比較。 The degree of influence of the kth stage can be calculated as the value of the above ratio (Fk/F) multiplied by the effective value. The effective value used herein may be a ratio relative to the rated value. The relationship between the degree of influence of the kth stage and the rated value is easy to understand and easy to compare.
控制裝置80可以將該處理結果顯示在顯示部72上。顯示部72例如可以顯示設定條件中之負載、設定條件是否適合等。設定條件中之負載可以作為有效值顯示，亦可以作為對於額定值之比例而以百分率顯示。亦可以同時顯示各階段的設定帶給有效值之影響度。 The control device 80 can display the processing result on the display unit 72. The display unit 72 can display, for example, the load in the setting conditions, whether the setting conditions are suitable, or the like. The load in the set condition can be displayed as an effective value or as a percentage of the rated value. It is also possible to simultaneously display the influence of the setting of each stage on the effective value.
當控制裝置80判斷為設定條件不適合時，可以向顯示部72和揚聲器輸出警報。能夠提醒用戶注意。 When the control device 80 determines that the setting condition is not suitable, an alarm can be output to the display unit 72 and the speaker. Can remind users to pay attention.
並且，當控制裝置80判斷為設定條件不適合時，可以對設定條件進行修正。例如，控制裝置80可以藉由追加等待時間，並延長成形週期時間，來將有效值設為額定值以下。並且，控制裝置80可以藉由延長閉模時間和開模時間，並延長成形週期時間，來將有效值設為額定值以下。 Further, when the control device 80 determines that the setting condition is not suitable, the setting condition can be corrected. For example, the control device 80 can set the effective value to be equal to or lower than the rated value by adding the waiting time and extending the molding cycle time. Further, the control device 80 can set the effective value to be equal to or lower than the rated value by extending the mold closing time and the mold opening time and extending the molding cycle time.
當控制裝置80修正設定條件時，可以以修正後的設 定條件來判斷在預定時間內預定射出數的成形是否可能。控制裝置80可在預定時間內預定射出數的成形未結束時再次修正設定條件。 When the control device 80 corrects the setting condition, the corrected setting can be used. The condition is determined to determine whether or not the formation of the predetermined number of shots within a predetermined time is possible. The control device 80 can correct the setting condition again when the formation of the predetermined number of shots is not completed within a predetermined time.
當控制裝置80判斷為設定條件不適合時，可以使模厚調整機構40作動，並進行合模裝置10的構件間的位置調整(本實施形態中調整後壓板15相對於固定壓板12之位置)。位置調整係為了調整合模馬達26的效率(合模馬達26的驅動力與合模力的比率)而進行的。由於控制量(例如合模力)與合模馬達26的負載之間的關係改變，因此可以改變設定條件是否適合的判斷。 When the control device 80 determines that the setting conditions are not suitable, the mold thickness adjusting mechanism 40 can be actuated to adjust the position between the members of the mold clamping device 10 (the position of the pressure plate 15 with respect to the fixed platen 12 after adjustment in the present embodiment). The position adjustment is performed in order to adjust the efficiency of the mold clamping motor 26 (the ratio of the driving force of the mold clamping motor 26 to the mold clamping force). Since the relationship between the control amount (for example, the mold clamping force) and the load of the mold clamping motor 26 is changed, it is possible to change the judgment as to whether or not the setting condition is suitable.
第3圖係表示本發明的一實施形態之合模力與合模馬達的負載之間的關係之圖。在第3圖中，L1表示最大合模力Cmax為Cmax1時的關係，L2表示最大合模力Cmax為Cmax2(Cmax2>Cmax1)時的關係，L3表示最大合模力Cmax為Cmax3(Cmax3>Cmax2)時的關係。 Fig. 3 is a view showing the relationship between the mold clamping force and the load of the mold clamping motor according to an embodiment of the present invention. In Fig. 3, L1 represents the relationship when the maximum mold clamping force C max is C max 1, and L2 represents the relationship when the maximum mold clamping force C max is C max 2 (C max 2 > C max 1), and L3 represents the maximum. The relationship when the mold clamping force C max is C max 3 (C max 3>C max 2).
最大合模力Cmax係用於上述位置調整者。在設定畫面中輸入有最大合模力Cmax時，自動進行上述位置調整，以在肘節機構20的姿勢為規定的姿勢時產生最大合模力Cmax。上述位置調整中可使用合模馬達26的編碼器26a、模厚馬達43的編碼器43a等。 The maximum clamping force C max is used for the above position adjuster. When the maximum mold clamping force C max is input to the setting screen, the above-described position adjustment is automatically performed to generate the maximum mold clamping force C max when the posture of the toggle mechanism 20 is a predetermined posture. In the above position adjustment, the encoder 26a of the mold clamping motor 26, the encoder 43a of the mold thickness motor 43, and the like can be used.
最大合模力Cmax例如為肘節機構20的連桿角度θ係預先設定之角度時產生之合模力。與最大合模力Cmax對應之連桿角度θ的設定可以改變。 The maximum mold clamping force C max is, for example, a mold clamping force generated when the link angle θ of the toggle mechanism 20 is a predetermined angle. The setting of the link angle θ corresponding to the maximum mold clamping force C max can be changed.
在閉模結束的狀態下肘節機構20的臂部越伸展，亦 即連桿角度θ變得越大，則會產生越大的合模力。但是，若肘節機構20完全伸展，亦即若連桿角度θ成為180°，則會在第1肘節桿22與肘節臂24的連結位置產生油膜撕裂等。 The more the arm portion of the toggle mechanism 20 is stretched in the state where the mold closing is completed, That is, the larger the link angle θ becomes, the larger the mold clamping force is generated. However, if the toggle mechanism 20 is fully extended, that is, if the link angle θ is 180°, oil film tearing or the like occurs at the connection position between the first toggle lever 22 and the toggle arm 24.
因此，最大合模力Cmax可設為連桿角度θ稍微小於180°時產生之合模力。另外，具有如下優點：當連桿角度θ成為180°時，能夠以合模馬達26停止之狀態保持合模力。因此，最大合模力Cmax亦可以設為連桿角度θ為180°時產生之合模力。 Therefore, the maximum mold clamping force C max can be set as the mold clamping force generated when the link angle θ is slightly smaller than 180°. Further, when the link angle θ is 180°, the mold clamping force can be maintained in a state where the mold clamping motor 26 is stopped. Therefore, the maximum mold clamping force C max can also be set as the mold clamping force generated when the link angle θ is 180°.
最大合模力Cmax設在合模裝置10的規格範圍內。另外，由於最大合模力Cmax係假想者，並不是在上述位置調整中實際產生者，因此亦可以超出合模裝置10的規格範圍。此時，可以限制十字頭21的移動範圍，以使合模力在合模裝置10的規格範圍內產生。 The maximum mold clamping force C max is set within the specification range of the mold clamping device 10. Further, since the maximum mold clamping force C max is a virtual person, it is not actually generated in the above-described position adjustment, and therefore may exceed the specification range of the mold clamping device 10. At this time, the range of movement of the crosshead 21 can be restricted so that the mold clamping force is generated within the specification range of the mold clamping device 10.
射出成形時的設定合模力C設為最大合模力Cmax以下，且設在合模裝置10的規格範圍內。設定合模力C與最大合模力Cmax相同時，由於合模時肘節機構20的臂部處於較伸展之狀態，因此合模時的肘節倍率較高，電力的利用效率良好。 The set mold clamping force C at the time of injection molding is set to be equal to or less than the maximum mold clamping force C max , and is set within the specification range of the mold clamping device 10 . When the clamping force C is set to be the same as the maximum mold clamping force C max , the arm portion of the toggle mechanism 20 is in a state of being stretched during the mold clamping. Therefore, the toggle ratio at the time of mold clamping is high, and the power utilization efficiency is good.
如第3圖所示，設定合模力C小於最大合模力Cmax時，合模馬達26的負載有時會超過額定(例如連續額定)。 As shown in Fig. 3, when the clamping force C is set to be smaller than the maximum clamping force Cmax , the load of the mold clamping motor 26 may exceed the rated value (e.g., continuous rating).
因此，控制裝置80依據最大合模力Cmax判斷設定合模力C是否適合。能夠避免合模馬達26的過負載引起之 停止。並且，與控制裝置80分開設置有資訊處理裝置時，能夠有助於購買射出成形機時的合模馬達26的選定。 Therefore, the control device 80 determines whether or not the set clamping force C is appropriate based on the maximum mold clamping force C max . It is possible to avoid the stop caused by the overload of the mold clamping motor 26. Further, when the information processing device is provided separately from the control device 80, it is possible to contribute to the selection of the mold clamping motor 26 when the injection molding machine is purchased.
第4圖係表示本發明的一實施形態之最大合模力Cmax、設定合模力C、及設定合模力C是否適合之間的關係之圖。在第4圖中，A1係判斷為設定合模力C適合之區域，A2係判斷為設定合模力C不適合之區域。另外，如上所述，設定合模力C設為最大合模力Cmax以下。 Fig. 4 is a view showing the relationship between the maximum mold clamping force C max , the set mold clamping force C, and the suitability of setting the mold clamping force C according to an embodiment of the present invention. In Fig. 4, A1 determines that the area where the mold clamping force C is suitable, and A2 determines that the mold clamping force C is not suitable. Further, as described above, the mold clamping force C is set to be equal to or less than the maximum mold clamping force C max .
控制裝置80中，例如將第4圖所示之資訊存儲於存儲部81，並在判斷設定合模力C是否適合時從存儲部81讀取該資訊而使用。如此，控制裝置80依據最大合模力Cmax來判斷設定合模力C是否適合。 In the control device 80, for example, the information shown in FIG. 4 is stored in the storage unit 81, and when it is determined whether or not the setting of the mold clamping force C is appropriate, the information is read from the storage unit 81 and used. In this manner, the control device 80 determines whether or not the set clamping force C is suitable based on the maximum mold clamping force C max .
另外，控制裝置80依據最大合模力Cmax計算與設定合模力C對應之合模馬達26的瞬間負載，可以依據計算出之瞬間負載判定設定合模力C是否適合。 Further, the control device 80 calculates the instantaneous load of the mold clamping motor 26 corresponding to the set mold clamping force C based on the maximum mold clamping force C max , and determines whether or not the mold clamping force C is suitable based on the calculated instantaneous load.
控制裝置80可以依據最大合模力Cmax及設定合模力C的保持時間來判斷設定合模力C是否適合。藉由對判斷材料中追加保持時間，能夠進行更詳細的判斷。 The control device 80 can determine whether or not the set clamping force C is appropriate based on the maximum mold clamping force C max and the holding time of the set mold clamping force C. A more detailed determination can be made by adding a hold time to the judgment material.
控制裝置80可以依據最大合模力Cmax、設定合模力C的保持時間及成形週期時間來判斷設定合模力C是否適合。藉由對判斷材料中追加保持時間和成形週期時間，能夠進一步進行詳細的判斷。 The control device 80 can determine whether or not the set clamping force C is suitable, based on the maximum mold clamping force C max , the holding time of the mold clamping force C, and the molding cycle time. Further detailed determination can be made by adding the holding time and the molding cycle time to the determination material.
例如，控制裝置80依據最大合模力Cmax、設定合模力C的保持時間及成形週期時間來計算合模馬達26的負 載的有效值，依據計算出之有效值判定設定合模力C是否適合。合模馬達26的負載用上述函數f(t)表示。該有效值為上述積分值F除以週期T的值之平方根。週期T為成形週期時間。將有效值與額定值進行比較，從而能夠避免週期運行時由異常檢測引起之停止。 For example, the control device 80 calculates the effective value of the load of the mold clamping motor 26 based on the maximum mold clamping force C max , the holding time of the mold clamping force C, and the molding cycle time, and determines whether the mold clamping force C is set based on the calculated effective value. Suitable for. The load of the mold clamping motor 26 is represented by the above function f(t). The effective value is the square root of the above-mentioned integral value F divided by the value of the period T. The period T is the forming cycle time. The effective value is compared with the rated value to avoid the stop caused by the abnormality detection during the cyclic operation.
當設定合模力C(C>0)在1個成形週期中被階段性地設定時，控制裝置80可以計算各階段的設定合模力C帶給是否適合的判斷之影響度。第k(k為1以上的自然數)階段的影響度例如在第k階段的保持時間內可計算對上述函數f(t)的平方值進行積分之值Fk與上述積分值F之比(Fk/F)。可知第幾階段的設定的影響度較大。 When the set clamping force C (C>0) is set stepwise in one molding cycle, the control device 80 can calculate the degree of influence of the determination of the appropriate clamping force C for each stage. The degree of influence of the kth (k is a natural number of 1 or more) stage, for example, in the holding time of the kth stage, the ratio of the value Fk integrating the square value of the above function f(t) to the above integral value F (Fk) /F). It can be seen that the influence of the setting of the first stage is large.
控制裝置80可以將該處理結果顯示在顯示部72上。顯示部72例如顯示設定合模力C是否適合等。各階段的設定合模力C的影響度亦可以同時顯示。 The control device 80 can display the processing result on the display unit 72. The display unit 72 displays, for example, whether or not the setting of the mold clamping force C is appropriate. The degree of influence of the setting clamping force C at each stage can also be displayed simultaneously.
當控制裝置80判斷為設定合模力C不適合時，可進行各種處理。作為處理內容可舉出輸出警報、提示設定合模力C的變更、停止運行等。當提示設定合模力C的變更時，可同時提示適合的設定合模力C的範圍。提示設定合模力C的變更可藉由例如顯示部72等進行。處理內容與判斷材料可建立對應關係，用戶可以設定該對應關係。 When the control device 80 determines that the set clamping force C is not suitable, various processes can be performed. The processing contents include an output alarm, a change in setting the mold clamping force C, and a stop operation. When the change of the mold clamping force C is prompted to be set, the range of the suitable mold clamping force C can be simultaneously indicated. The change in the setting of the mold clamping force C can be performed by, for example, the display unit 72 or the like. The processing content and the judgment material can establish a correspondence relationship, and the user can set the correspondence relationship.
另外，本實施形態的模具裝置30係具有彈簧部者，但對模具裝置的構成並沒有特別限定。例如可以使用油壓缸代替彈簧部來作為配設於模具主體部與框狀部之間之構件。並且，模具裝置30亦可以是鎖扣型等。 Further, the mold device 30 of the present embodiment has a spring portion, but the configuration of the mold device is not particularly limited. For example, a hydraulic cylinder may be used instead of the spring portion as a member disposed between the mold main body portion and the frame portion. Further, the mold device 30 may be of a lock type or the like.
以上，對射出成形機的實施形態等進行了說明，但本發明並不限定於上述實施形態等，在技術方案中所記載之本發明的宗旨的範圍內，可以進行各種變形及改良。 In the above, the embodiment of the injection molding machine has been described. However, the present invention is not limited to the above-described embodiments, and various modifications and improvements can be made within the scope of the gist of the invention described in the claims.
例如，上述實施形態的射出成形機為模開閉方向為水平方向的臥式射出成形機，但亦可以為模開閉方向為上下方向的立式射出成形機。立式合模裝置具有作為固定壓板的下壓板、作為可動壓板的上壓板、肘節座、肘節機構及模厚調整機構等。下壓板上安裝有下模具，上壓板上安裝有上模具。由下模具和上模具構成模具裝置。下模具可以經由轉台安裝於下壓板。肘節座配設於下壓板的下方，與上壓板一同升降。肘節機構配設於肘節座與下壓板之間。模厚調整機構由外螺紋、內螺紋及模厚馬達等構成。外螺紋形成於繫桿，繫桿連結肘節座和上壓板。內螺紋旋轉自如地保持在肘節座或上壓板上。模厚馬達藉由使與外螺紋螺合之內螺紋旋轉，來調整肘節座與上壓板的相對位置。 For example, the injection molding machine of the above-described embodiment is a horizontal injection molding machine in which the mold opening and closing direction is horizontal, but a vertical injection molding machine in which the mold opening and closing direction is the vertical direction may be used. The vertical mold clamping device has a lower pressure plate as a fixed pressure plate, an upper pressure plate as a movable pressure plate, a toggle joint, a toggle mechanism, and a mold thickness adjustment mechanism. A lower mold is mounted on the lower platen, and an upper mold is mounted on the upper platen. The mold device is constituted by the lower mold and the upper mold. The lower mold can be mounted to the lower platen via a turntable. The elbow seat is disposed below the lower platen and is raised and lowered together with the upper platen. The toggle mechanism is disposed between the toggle seat and the lower platen. The mold thickness adjustment mechanism is composed of an external thread, an internal thread, and a mold thickness motor. The external thread is formed on the tie rod, and the tie rod connects the toggle joint and the upper pressure plate. The internal thread is rotatably held on the toggle seat or the upper platen. The die thickness motor adjusts the relative position of the toggle seat to the upper platen by rotating the internal thread that is screwed to the external thread.
並且，上述實施形態的模具裝置對模穴空間內的成形材料進行壓縮，但亦可以不對模穴空間內的成形材料進行壓縮。 Further, although the mold apparatus of the above embodiment compresses the molding material in the cavity space, the molding material in the cavity space may not be compressed.
並且，上述實施形態的資訊處理裝置對作為合模裝置10的驅動部的合模馬達26的資訊進行處理，但對驅動部的種類並沒有特別限定。例如，資訊處理裝置亦可以對射出裝置50的驅動部、頂出裝置的驅動部等的資訊進行處理。並且，驅動部可以不是馬達，亦可以是油壓缸或電磁鐵等。 Further, the information processing device of the above-described embodiment processes the information of the mold clamping motor 26 as the drive unit of the mold clamping device 10, but the type of the drive unit is not particularly limited. For example, the information processing device may process information such as a drive unit of the injection device 50 and a drive unit of the ejector unit. Further, the driving portion may not be a motor, and may be a hydraulic cylinder or an electromagnet.
並且，上述實施形態的合模裝置10中作為驅動部而具有合模馬達26，但亦可以具有油壓缸來代替合模馬達26。並且，合模裝置10可以具有線性馬達，用於模開閉，並具有電磁鐵，用於合模。電磁鐵型的合模裝置例如具有固定壓板、可動壓板、後壓板、吸附板及模厚調整機構等。可動壓板在固定壓板與後壓板之間進退自如。固定壓板與後壓板藉由繫桿連結。吸附板在後壓板的後方與可動壓板一同進退自如。可動壓板與吸附板藉由桿連結，該桿插穿於後壓板的貫穿孔。在後壓板及吸附板中的至少一個上形成電磁鐵，電磁鐵之吸附力作用於後壓板與吸附板之間，並產生合模力。模厚調整機構由外螺紋、內螺紋及模厚馬達等構成。外螺紋形成在桿上，內螺紋旋轉自如地保持在吸附板或可動壓板上。模厚馬達藉由使與外螺紋螺合之內螺紋旋轉，來調整吸附板與可動壓板的相對位置。由此，閉模結束時，在吸附板與後壓板之間形成規定的間隙。 Further, in the mold clamping device 10 of the above-described embodiment, the mold clamping motor 26 is provided as a driving portion, but a hydraulic cylinder may be provided instead of the mold clamping motor 26. Also, the mold clamping device 10 may have a linear motor for mold opening and closing and an electromagnet for clamping. The electromagnet type mold clamping device includes, for example, a fixed platen, a movable platen, a rear platen, an adsorption plate, and a mold thickness adjusting mechanism. The movable platen can move forward and backward between the fixed platen and the rear platen. The fixed platen and the rear platen are connected by a tie rod. The suction plate is retracted with the movable platen at the rear of the rear platen. The movable platen and the suction plate are coupled by a rod which is inserted through the through hole of the rear platen. An electromagnet is formed on at least one of the rear platen and the adsorption plate, and an adsorption force of the electromagnet acts between the rear platen and the adsorption plate to generate a mold clamping force. The mold thickness adjustment mechanism is composed of an external thread, an internal thread, and a mold thickness motor. The external thread is formed on the rod, and the internal thread is rotatably held on the adsorption plate or the movable platen. The mold thickness motor adjusts the relative position of the suction plate and the movable platen by rotating the internal thread that is screwed to the external thread. Thereby, a predetermined gap is formed between the adsorption plate and the rear platen at the end of the mold closing.
