Described mold layout is mould two chamber, cold runner side gate pouring type, as shown in Figure 2 and Figure 3.
During real work, as shown in Fig. 7, Figure 12, Figure 13, its motion operation principle is as follows:
1) convertible oblique top head ejecting mechanism A operation principle
In Fig. 7, PL0 is mould moving platen 33 bottom surface, and PL1 is a top board 34 top board face, and PL2 is secondary top board 36 top board face, and PL3 is three top board 37 top board faces; S is that PL1 upwards ejects space length; M is depicted as and upwards ejects direction; T0, T1 are push rod rotation direction; R0, R1 are the direction of motion of the slide-and-guide circular groove on the first push rod rotational pin 7, second push rod rotational pin 10 opposite central jacking block 1 head; First push rod 6, second push rod 11 is installed on PL1 face; Central authorities' jacking block base 17 is installed on PL2 face; Central authorities' push rod 8 is installed on PL3 face; Ejecting of product point to be carried out for three times by mechanism.
Actual when ejecting work, convertible oblique top head ejecting mechanism A ejects a point following step and completes:
1.1) product from the first demoulding core mold insert under upwards the pushing of injection machine push rod, the functor be mounted thereon of each PL1, PL2, PL3 and correspondence by M shown in Fig. 7 to upwards ejecting, thus entirety by product from the demoulding mold cores mold insert, the distance S0<S that this stage upwards ejects; What this was mechanism once ejects;
1.2) rotating stripping demoulding of two ends button bit is after once having ejected, PL1 face and be mounted thereon functor and namely can not continue to have moved upward ejecting on direction, and it is slack, PL2, PL3 face and on function part then continue upwards to eject, in ejection process, due to the first push rod rotational pin 7, second push rod rotational pin 10 can not continue up, and central jacking block 1 is when continuing up, gathering sill shown in Fig. 6 on it will force the first push rod rotational pin 7, the R0 that it is the center of circle with central transverse axis block 9 center line that second push rod rotational pin 10 does as shown in Figure 7, the relative motion in direction shown in R1, final first push rod rotational pin 7 will pull the 3rd fan-shaped circular arc switch block 4, four fan-shaped circular arc switch block 5 rotates the demoulding, second push rod rotational pin 10 will pull the first fan-shaped circular arc switch block 2, second fan-shaped circular arc switch block 3 rotates the demoulding, thus completing the demoulding of the two ends of product shown in Fig. 1 button bit, process is as shown in Fig. 7 (a), Fig. 7 (b), this is the Double-ejection of mechanism,
1.3) product eject completely after the rotating stripping demoulding of two ends button bit completes, PL2 can not continue up, will stop, but PL3 can continue upwards to eject, product finally ejects by central push rod 8 on it completely, and as shown in Fig. 7 (c), this is ejecting for three times of mechanism;
1.4), when resetting, the mould release link on PL3 pushes back PL3 and resets, and PL3 pulls PL2, PL1 to reset successively, thus ensures that PL1, PL2, PL3 and upper functor thereof return reset by PL3-PL2-PL1 successively.
2) three ejecting mechanism B operation principles
2.1) once eject when three top boards 37 eject by direction shown in K1 in Figure 12 (a) by injection machine push rod, three times top board 37 will by left Zhi Suowei block 22, right Zhi Suowei block 23 promotes secondary top board 36, one time top board 34 is synchronized with the movement, after the c point on the slip lock core 25 on a top board 34 moves to the displacement arc groove at a point place on master lock position block 21, left Zhi Suowei block 22, right Zhi Suowei block 23 moves forcing slip lock core 25 in the displacement arc groove on master lock position block 21, direction as shown in F1 in Figure 12 (b), thus a top board will stop motionless, mechanism completes and ejects holding function for the first time, as Figure 12 (a), shown in Figure 12 (b),
2) Double-ejection injection machine push rod continues to eject, secondary top board 36 continues to move upward by direction shown in K1, after d point on slip lock core 25 on secondary top board 36 moves to the displacement arc groove at b point place on master lock position block 21, left Zhi Suowei block 22, right Zhi Suowei block 23 move forcing slip lock core 25 in the displacement arc groove on master lock position block 21, direction as shown in F2 in Figure 13 (a), thus secondary top board 36 will stop motionless, mechanism completes second time and ejects holding function, as shown in Figure 12 (a), Figure 13 (a);
3) eject injection machine push rod for three times to continue to eject, until three top boards 37 are stopped stopping by secondary top board 36, as shown in Figure 13 (b), thus three times that complete three ejecting mechanism B eject controlling functions.
4) under resetting at the pulling of injection machine push rod, three times top board 37 is first reset, then secondary top board 36 is pulled to reset by three top boards 37 by Double-ejection sheet reset pull bar 29, synchronously, a top board 34 is pulled to reset by secondary top board 36 by a liftout plate reset lever 28, when reset completes, reset stroke switch 27 sends reset settling signal.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit, those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
