Detailed description of the invention
For making the utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
As shown in Figure 1, Figure 2 and Figure 3, the utility model provides a kind of injection mold twice ejecting mechanism, comprises guide pad 1, slide block 2, pushing block 3 and spring 4.The lower end of guide pad 1 is the guide part with inclined-plane two, and slide block 2 is positioned at the below of guide pad 1, is provided with spring 4 in the side of slide block 2, is provided with groove at the middle part of slide block 2, and a sidewall of groove is inclined-plane one, has through hole in the end of slide block 2.Pushing block 3 is positioned at the below of sliding 2.
Injection mold in the utility model comprises dynamic model gripper shoe 11, upper strata push rod fixed head 10, upper strata push pedal 9, upper strata push rod fixed head 8, lower floor's push pedal 7 from top to bottom successively.Guide pad 1 is fixed in dynamic model gripper shoe 11 by bolt 13, and guide pad 1 is through after upper strata push rod fixed head 10, and the inclined-plane two of its guide part contacts with the inclined-plane one of slide block 2.Slide block 2 is located in upper strata push pedal 9, is provided with spring 4 between slide block 2 and upper strata push pedal 9, and slide block 2 can do being displaced sideways of certain limit in upper strata push pedal 9.Pushing block 3 is fixed in lower floor's push pedal 7 by bolt 5.Pushing block 3 contacts with slide block 2 with upper strata push pedal 9 through lower floor's push rod fixed head 8.Upper strata push rod fixed head 10 and lower floor's push rod fixed head 8 are respectively equipped with upper strata push rod 12 and lower floor's push rod 15, and lower floor's push pedal has injection machine push rod 6, and dynamic model gripper shoe 11 is provided with thrust block 14, and thrust block 14 is fixed by bolt 15 and dynamic model gripper shoe 11.
As shown in Figure 2, produce after mould die sinking and eject action, injection machine push rod 6 promotes lower floor's push pedal 7, and promote slide block 2 by pushing block 3, slide block 2 promotes upper strata push rod fixed head 10 and moves, thus upper strata push rod 12 action together with lower floor push rod 15 ejects plastic products, and plastic products are pushed away core rod.Slide block 2 is owing to being that inclined-plane coordinates with guide pad 1, and guide pad 1 is fixed, and in the process ejected, slide block 2, except moving along ejecting direction, produces cross component force and lateral displacement simultaneously under the effect on inclined-plane.Ejecting certain position, as shown in Figure 3, thrust block 14 limits the movement of layer push rod fixed head 10, corresponding upper strata push rod 12 stops mobile, now slide block 2 is moved laterally to the position of the center of its through hole and the center superposition of pushing block 3, and at this moment pushing block 3 can be without hindrance through slide block 2, by slide block 2, thrust can not be passed to upper strata push rod fixed head 10 again, and lower floor's push pedal 7 can continue mobile, lower floor's push rod 16 is driven thoroughly to push up plastic products from mould.Eject after action completes, during backhaul, rely on mould retracting spring elastic force, lower floor's push pedal 7 and upper strata push pedal 9 return, pushing block 3 exits the through hole of slide block 2, and slide block 2 gets back to original state under the effect of spring 4.
