In step 203, the mold flow analysis software can analyze and predict The molding time T0 is set, and after each screw speed and each screw stroke position corresponding to each turning point are obtained, one of the partitioning time in each screw stroke position is obtained according to each screw stroke position and the corresponding screw speed (step 209). Wherein each partition time is equal to the difference between the adjacent two screw stroke positions divided by the corresponding screw speed.
舉例來說，如第1圖及第4圖所示，當螺桿以第一螺桿速率v1自初始螺桿衝程位置P0移動至第一螺桿衝程位置P1內之一第一分區時間t1、當螺桿以第二螺桿速率v2自第一螺桿衝程位置P1移動至第二螺桿衝程位置P2內之一第二分區時間t2、當螺桿以第三螺桿速率v3自第二螺桿衝程位置P2移動至第三螺桿衝程位置P3內之一第三分區時間t3以及當螺桿以第四螺桿速率v4自第三螺桿衝程位置P3移動至第四螺桿衝程位置P4內之一第四分區時間t4可分別以下列關係式求得：For example, as shown in FIGS. 1 and 4, when the screw moves from the initial screw stroke position P0 to the first screw stroke position P1 at the first screw speed v1, the first partition time t1, when the screw is The second screw speed v2 is moved from the first screw stroke position P1 to one of the second screw stroke positions P2 at a second partition time t2, when the screw moves from the second screw stroke position P2 to the third screw stroke position at the third screw speed v3 One of the third partition time t3 in P3 and one of the fourth partition time t4 when the screw is moved from the third screw stroke position P3 to the fourth screw stroke position P4 at the fourth screw speed v4 can be obtained in the following relationship:
第一分區時間t1 =(第一螺桿衝程位置P1-初始螺桿衝程位置P0) / 第一螺桿速率v1；First partition time t1 = (first screw stroke position P1 - initial screw stroke position P0) / first screw speed v1;
第二分區時間t2 =(第二螺桿衝程位置P2-第一螺桿衝程位置P1)/ 第二螺桿速率v2；Second partition time t2 = (second screw stroke position P2 - first screw stroke position P1) / second screw speed v2;
第三分區時間t3 =(第三螺桿衝程位置P3-第二螺桿衝程位置P2) / 第三螺桿速率v3；Third partition time t3 = (third screw stroke position P3 - second screw stroke position P2) / third screw speed v3;
第四分區時間t4 =(第四螺桿衝程位置P4-第三螺桿衝程位置P3)/ 第四螺桿速率v4；Fourth partition time t4 = (fourth screw stroke position P4 - third screw stroke position P3) / fourth screw speed v4;
接著，將各分區時間累加而得總時間T(步驟210)，舉例來說，如第4圖所示，總時間T、第一分區時間t1、第二分區時間t2、第三分區時間t3以及第四分區時間t4滿足下列關係式：Then, the partition time is accumulated to obtain the total time T (step 210). For example, as shown in FIG. 4, the total time T, the first partition time t1, the second partition time t2, the third partition time t3, and The fourth partition time t4 satisfies the following relationship:
總時間T =第一分區時間t1 + 第二分區時間t2 + 第三分區時間t3 + 第四分區時間t4；Total time T = first partition time t1 + second partition time t2 + third partition time t3 + fourth partition time t4;
接著，將總時間T與預設成型時間T0比較(步驟211)，若總時間T與預設成型時間T0相符，即總時間T實質上等於預設成型時間T0，則將第一螺桿速率v1、第一螺桿衝程位置P1、第二螺桿速率v2、第二螺桿衝程位置P2、第三螺桿速率v3、第三螺桿衝程位置P3、第四螺桿速率v4以及第四螺桿衝程位置P4提供給成型機台1(步驟 212)，亦即將第一螺桿速率v1、第一螺桿衝程位置P1、第二螺桿速率v2、第二螺桿衝程位置P2、第三螺桿速率v3、第三螺桿衝程位置P3、第四螺桿速率v4以及第四螺桿衝程位置P4分別鍵入第3圖所示之成型機台操作系統介面4的對應欄位中。Next, the total time T is compared with the preset molding time T0 (step 211). If the total time T coincides with the preset molding time T0, that is, the total time T is substantially equal to the preset molding time T0, the first screw speed v1 is obtained. a first screw stroke position P1, a second screw speed v2, a second screw stroke position P2, a third screw speed v3, a third screw stroke position P3, a fourth screw speed v4, and a fourth screw stroke position P4 are supplied to the molding machine. Stage 1 (step 212), that is, first screw speed v1, first screw stroke position P1, second screw speed v2, second screw stroke position P2, third screw speed v3, third screw stroke position P3, fourth The screw speed v4 and the fourth screw stroke position P4 are respectively entered into the corresponding fields of the molding machine operating system interface 4 shown in FIG.
若總時間T與預設成型時間T0不相符，即總時間T不等於預設成型時間T0，則利用總時間T相對於預設成型時間T0的比值調整各螺桿速率，並將各轉折點對應的各螺桿衝程位置及調整後的各螺桿速率提供給成型機台1(步驟 213)，即當總時間T與預設成型時間T0不相符時，需調整第一螺桿速率v1、第二螺桿速率v2、第三螺桿速率v3以及第四螺桿速率v4。If the total time T does not coincide with the preset molding time T0, that is, the total time T is not equal to the preset molding time T0, the screw speed is adjusted by the ratio of the total time T to the preset molding time T0, and the respective turning points are corresponding. Each screw stroke position and the adjusted screw speed are supplied to the molding machine 1 (step 213), that is, when the total time T does not coincide with the preset molding time T0, the first screw speed v1 and the second screw speed v2 are adjusted. The third screw speed v3 and the fourth screw speed v4.
舉例來說，當總時間T與預設成型時間T0不相符時，調整後的第一螺桿速率v1'、調整後的第二螺桿速率v2'、調整後的第三螺桿速率v3'以及調整後的第四螺桿速率v4'可分別以下列關係式求得：For example, when the total time T does not match the preset molding time T0, the adjusted first screw speed v1', the adjusted second screw speed v2', the adjusted third screw speed v3', and the adjusted The fourth screw speed v4' can be obtained by the following relationship:
第一螺桿速率v1' =第一螺桿速率v1 *總時間T /預設成型時間T0；First screw speed v1' = first screw speed v1 * total time T / preset molding time T0;
第二螺桿速率v2' =第二螺桿速率v2 *總時間T /預設成型時間T0；Second screw speed v2' = second screw speed v2 * total time T / preset molding time T0;
第三螺桿速率v3' =第三螺桿速率v3 *總時間T /預設成型時間T0；Third screw speed v3' = third screw speed v3 * total time T / preset molding time T0;
第四螺桿速率v4' =第二螺桿速率v4 *總時間T /預設成型時間T0；Fourth screw speed v4' = second screw speed v4 * total time T / preset molding time T0;
接著，將第一螺桿速率v1'、第一螺桿衝程位置P1、第二螺桿速率v2'、第二螺桿衝程位置P2、第三螺桿速率v3'、第三螺桿衝程位置P3、第四螺桿速率v4'以及第四螺桿衝程位置P4提供給成型機台1，亦即將第一螺桿速率v1'、第一螺桿衝程位置P1、第二螺桿速率v2'、第二螺桿衝程位置P2、第三螺桿速率v3'、第三螺桿衝程位置P3、第四螺桿速率v4'以及第四螺桿衝程位置P4分別鍵入第3圖所示之成型機台操作系統介面4的對應欄位中。Next, the first screw speed v1', the first screw stroke position P1, the second screw speed v2', the second screw stroke position P2, the third screw speed v3', the third screw stroke position P3, the fourth screw speed v4 'and the fourth screw stroke position P4 is supplied to the forming machine 1, that is, the first screw speed v1', the first screw stroke position P1, the second screw speed v2', the second screw stroke position P2, the third screw speed v3 The third screw stroke position P3, the fourth screw speed v4', and the fourth screw stroke position P4 are respectively entered into corresponding fields of the molding machine operating system interface 4 shown in FIG.
