DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The technical contents of the present invention will become apparent with the detailed description of preferred embodiments accompanied with the illustration of related drawings as follows. It is intended that the embodiments and figures disclosed herein are to be considered illustrative rather than restrictive.

[0016] With reference to FIG. 4 for a process control method of the present invention, the process control method comprises a status monitoring, a temperature setting, a mold locking setting, a front injection/feeding setting, an ejection/blowing setting, a function/time setting, an automated process setting, a production control, a core setting, a purging and injection setting, and a rear injection/feeding setting, wherein the automated process setting 2 includes a mold-opening ending process setting 21 and a mold-closing ending process setting 22. The mold-opening ending process setting 21 is a setting selected from a mold-opening ending automated process option 23. In an embodiment of the present invention, the mold-opening ending automated process option 23 includes: NO action; 1: Rotating action (moving a support base of a male mold to rotate accordingly); 2: Ejecting action (moving the middle ejector forward, and pushing the molded product to move accordingly); 3: Ejector retreat (retreating the middle ejector with the movement); 4: Front and rear eject (The front and rear pushers will move forward with the movement to push out the molded product); 5: Middle and front eject (The middle and front pushers will move forward in correspondence with the rotation to push out the molded product); 6: Core 1 out (the Core 1 of the mold will move outwardly from the mold); 7: Core 1 in (the Core 1 of the mold will move inwardly from the mold); 8: Core 2 out (The Core 2 of the mold will move outwardly from the mold); 9: Core 2 in (The Core 2 of the mold will move inwardly from the mold; 10: Core 3 out (The Core 3 of the mold will move outwardly from the mold); 11: Core 3 in (The Core 3 of the mold will move inwardly from the mold); 12: Rotation advance Core 1 repeat, and Rotation advance Core 2 repeat (moving the support base of the male mold to rotate forward, and the core will move out and in when the support base of the male mold support base rotates backward, and when the action is carried out, the Core 2 will move out and in); 13: Front and rear ejectors retreat (The front and rear pushers will move backward); 14: End of cycle (The mold-opening ending process of the automated process ends); and 15: Open/close safety door (The safety door will be opened and then closed). The mold-closing ending process setting 22 is a setting selected from a mold-closing ending automated process option 24 according to each switching action. In an embodiment of the present invention, Action 1 of the mold-closing ending process setting 22 includes No action; 1: Ejecting action (The middle ejector will move forward to push the molded product with the movement) or 2: Core 3 in (The Core 3 of the mold will move inwardly from the mold); Action 2 and Action 4 of the mold-closing ending process setting 22 include No action; 1: Two-color simultaneous injection (the raw materials of two different colors are injected from the material pipes simultaneously); 2: Front injection (The materials are injected through the front of the mold); or 3: Rear injection (The materials are injected through the rear of the mold); Action 3 of the mold-closing ending process setting 22 include No action; 1: Ejector retreat (The middle ejector moves backward); 2: Core 3 out (The Core 3 of the mold will move outwardly from the mold); 3. Ejecting action (The middle ejector will move forward to push out the molded product with the movement); or 4: Core 3 in (The Core 3 of the mold will move inwardly from the mold); Action 5 of the mold-closing ending process setting 22 include No action; 1: Ejector retreat (The middle ejector will move backward) or 2: Core 3 out (The Core 3 of the mold will move the mold outward).

[0017] In an embodiment of the present invention as shown in FIG. 4, when the automated process setting 2 is applied to a two-color injection molding machine, its mold-opening ending process setting 21 includes a plurality of action option settings 211 of a rotation-advance ending and a rotation-retreat ending, and the plurality of action option settings 211 are carried out sequentially after a setting is selected from the mold-opening ending automated process option 23 as shown in FIG. 5. Action 1 of the rotation-advance ending action option setting 211 of the mold-opening ending process setting 21 is NO action; Action 2 is 4: Front and rear eject; Action 3 is 14: End of cycle, Actions 4 to 10 are all NO actions. Actions 1 to 10 of the rotation-retreat ending action option setting 211 are all NO actions, indicating that after the injection molding machine has completed carrying out the actions from mold-opening to mold-opening, the front and rear pusher will move forward with the movement to push out the molded product [Action 2], and then the rotation-advance ending of the automated process ends [Action 3]. Actions 1 to 10 of the rotation-retreat ending action option setting 211 of the mold-opening ending process setting 21 are all NO actions. The mold-closing ending process setting 22 is a setting selected from a mold-closing ending automated process option 24 according to each switching action, and Action 1 of the action option setting 221 of the mold-closing ending process setting 22 is NO action; Action 2 is 1: Two-color simultaneous injection; Actions 3 to 5 are all NO actions indicating that after the injection molding machine has completed executing the mold-closing to the completion of the mold-closing, the raw materials of two different raw materials are injected from the material pipes simultaneously [Action 2].

[0018] In an embodiment of the present invention as shown in FIG. 6, the automated process setting 2 is applied to a three-color injection molding machine, and its mold-opening ending process setting 21 comprises a plurality of action option settings 211 of a first rotation-advance ending, a second rotation-advance ending and a third rotation-advance ending, and the plurality of action option settings 211 are carried out sequentially after a setting is selected from a mold-opening ending automated process option 23, and the mold-closing ending process setting 22 is a setting selected from a mold-closing ending automated process option 24 according to each switching action.

[0019] Therefore, the multi-color injection molding machine can use the page of the automated process setting 2 together with the desired action option to click and select a setting according to different injection molding objects or molds to complete the correction and setting of an injection stroke quickly, so as to improve the operational efficiency of the injection molding.
