Embodiment
In order that present disclosure is easier to be clearly understood, it is right below according to specific embodiment and with reference to accompanying drawing The present invention is described in further detail.
A kind of three ejecting mechanisms for injection mold as shown in Figure 1, including the Bottom clamp plate set from bottom to top 1st, cushion block 5, moving platen 7 and solid plate 8, moving platen 7 and the centre position of solid plate 8 offer running channel 10, moving platen 7 and solid plate Insert 6 and cover half mold insert 9 are provided between 8, provided with side core 12 and for being formed between insert 6 and cover half mold insert 9 The die cavity of plastic 11, the upper middle position of the Bottom clamp plate 1 from bottom to top provided with lower push pedal 2, upper push pedal fixed plate 3 and on Push pedal 4, the upper push pedal fixed plate 3 is provided with push rod 16 and differential push rod 14, and the upper push pedal 4 is provided with upper release link 15, The lower push pedal 2 is provided with lower release link 17 and running channel push rod 13, and the running channel push rod 13 is connected with running channel 10.The differential top It is that gap coordinates between bar 14 and upper push pedal fixed plate 3, upper push pedal 4;The differential push rod 14 is symmetrical arranged, and each die cavity is set There are two differential push rods 14;The push rod 16 is symmetrical arranged, and each die cavity is provided with a push rod 16;The lower release link 17 is with moving Release link briquetting 18 is provided between die holder plate 1, push rod briquetting 19 is provided between the push rod 16 and upper push pedal fixed plate 3, it is described Cushion block 5 is L-shaped.
As shown in Fig. 2 the differential push rod 14 includes shoulder 141 and longer portion 143 positioned at the both sides of shoulder 141 and shorter Portion 142, the longer portion 143 pass through moving platen 7 and insert 6, the shorter portion 142 through upper push pedal 4 and with upper push pedal The via clearance of fixed plate 3 coordinates;The diameter of the shoulder 141 is more than the diameter in the shorter portion 142, the shorter portion 142 Diameter be more than the diameter in the longer portion 143.
The operation principle of the present invention is as follows:
(1) ejection is waited:
During die sinking, injection machine driven mold dynamic model part is moved and drives side core-drawing mechanism to act, and removes side core 12, Die sinking motion stops afterwards to terminal, waits ejection.
(2) once eject:
As shown in figure 3, during ejection, injection machine push rod promotes lower push pedal 2, lower release link 17, running channel push rod 13 upward first Motion, cuts off tunnel gate and ejects condensed material in runner 20, until lower push pedal 2 is contacted with upper push pedal fixed plate 3, completion is once pushed up Go out.
(3) Double-ejection:
As shown in figure 4, ejecting mechanism continuation is acted, promote lower push pedal 2, upper push pedal fixed plate 3 and upper push pedal 4 simultaneously upward Move, due to there is gap at differential push rod 14 and upper push pedal fixed plate 3 and the contact surface of upper push pedal 4, therefore differential push rod 14 is static It is motionless.The gap that then upward motion compensation side core 12 is removed of push rod 16 is simultaneously in contact with the surface of plastic 11, and running channel push rod 13 Continue up, eject condensed material in runner 20, it is complete to the lower surface of the shoulder of differential push rod 14 and the surface of upper push pedal fixed plate 3 During Full connected, Double-ejection is completed.
(4) three ejections:
As shown in figure 5, ejecting mechanism continuation is acted, promote lower push pedal 2, upper push pedal fixed plate 3 and upper push pedal 4 simultaneously upward Motion, differential push rod 14 and the Union Movement of push rod 16 eject plastic 11, and running channel push rod 13 is continued up, dynamic to ejecting Work stops, and completes three ejections.
(5) reset:
During matched moulds, injection machine push rod retracts, and lower push pedal 2 resets first in the presence of lower release link 17;Subsequent side core-pulling Reset simultaneously drives push rod 16, and upper push pedal fixed plate 3 resets;Finally, in the presence of upper release link 15, upper push pedal 4 resets, Main parting line is closed, and mould matched moulds process is completed.
It should be noted that particular embodiments described above, pair present invention solves the technical problem that, technical scheme and have Beneficial effect is further described.It is noted that the technological means disclosed in the present invention program is not limited only to above-mentioned reality The technological means disclosed in mode is applied, in addition to by the constituted technical scheme of above technical characteristic any combination.For this skill For the those of ordinary skill in art field, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, These improvements and modifications are also considered as protection scope of the present invention.
