Detailed description of the invention
Fig. 1-4 is depicted as related description figure of the present invention; A kind of two curved pin list latch segment front mould internal core-pulling mechanism, comprise in the first curved pin 1, first taking out in slide block 2, first to take out in sliding block spring 3, first side slide 4, central core 5, second side slide 6, second to take out in sliding block spring 7, second and take out the curved pin 9 of slide block 8, second, central briquetting 10, as shown in Figure 2.
The curved pin 9 of described first curved pin 1, second, central briquetting 10 by screw fastening be installed on the mould template that depends on.
Described first side slide 4, second side slide 6 be installed on the mould template that depends on; Take out in first in slide block 2, first to take out in sliding block spring 3, second to take out in sliding block spring 7, second and take out slide block 8 and be installed on the mould template that depends on.
Take out in described first in slide block 2, first side slide 4, central core 5, second side slide 6, second and take out the curved pin 9 of slide block 8, second, a part of forming part that central briquetting 10 is product.
Further, illustrate for ease of operation principle of the present invention, need the mould mating parts pointed out to comprise upper clamping plate 11, die cavity accessory plate 12, impression bolster 13, core fixing plate 14 in Fig. 3, die cavity accessory plate 12 and impression bolster 13 are coupled as one by screw fastening; Corresponding, the curved pin 9 of the first curved pin 1, second, central briquetting 10 by screw fastening be installed on the mould template upper clamping plate 11 that depends on; First side slide 4, second side slide 6 be installed on the mould template core fixing plate 14 that depends on; Take out in first in slide block 2, first to take out in sliding block spring 3, second to take out in sliding block spring 7, second and take out slide block 8 and be installed on the mould template impression bolster 12 that depends on; It is to be noted in Fig. 4 that mould first somatotype that PL1 is depended on by mechanism opens face, PL2 is that the second somatotype opens face; The curved pin 9 of first curved pin 1, second lead angle of loosing core is 8 °; Taking out in slide block 2, second in first curved pin 1, the second curved pin 9 and first and taking out between slide block 8 inner curved pin-and-hole gap under closure state is 0.3mm; Central authorities' briquetting 10 lower end inclination angle of inclined plane is 10 °.
During real work, as shown in Figure 4, its motion operation principle is as follows:
1) after central inner core pulling demoulding mould die cavity is opened, under the pulling of injection machine push rod, mould dynamic model part progressively retreats with cover half part and is separated, and now, mould is first opened at PL1 die joint place, die cavity accessory plate 12, impression bolster 13, core fixing plate 14 remains closed, the first curved pin 1, second curved pin 9, central authorities' briquetting 10 stays on upper clamping plate 11, is greater than the first curved pin 1 because central briquetting 10 lower end inclination angle of inclined plane is 10 °, second curved pin 9 lead angle of loosing core is 8 °, so, in first, take out slide block 2, when taking out slide block 8 synchronous retrogressing equidistance in second, central briquetting 10 takes out slide block 2 in first, speed and the distance of taking out the contact surface of slide block 8 in second are all greater than the first curved pin 1, slide block 2 is taken out in second curved pin 9 and first, speed and the distance of curved pin-and-hole contact surface on slide block 8 is taken out in second, thus, in first, take out sliding block spring 3, under taking out the bounce auxiliary pushing of sliding block spring 7 in second, ensure that the first curved pin 1, second curved pin 9 promotes to take out slide block 2 in first, take out slide block 8 in second to mould central contraction, complete the inner core pulling demoulding of recessed button bit inside product central part,
2) the core_pulling demoulding mould of lateral surface is opened in PL2 punishment type, and under the effect of mold slanted guide pillar, the first side slide 4, second side slide 6, respectively to outer extraction, completes the core_pulling demoulding of product side;
3), after product ejecting product completes the inner core pulling demoulding of heart portion and outer side core_pulling demoulding, by the ejection system of mould, product is ejected from central core 5 completely;
4) when resetting, process is contrary with die sinking process, before mold cavity is closed, first go out closed at PL2, first side slide 4, second side slide 6 first resets, and then goes out at PL1 closed, takes out in slide block 2, second and take out slide block 8 synchronous reset in first, mould is completely closed, waits for that next injection cycle starts.
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.
