Embodiment
The present invention is described in further details with reference to the accompanying drawings and detailed description.
As shown in Figures 1 to 4, provided in this embodiment is a kind of Double-ejection control mechanism, applied to injection mold, mould
Tool includes dynamic mould fixing plate 1, and the support block 2 on dynamic mould fixing plate 1, the core fixing plate 3 on support block 2, is located at
The pusher plate 4 of the top of core fixing plate 3 and upper ejector retainner plate 5, lower ejector retainner plate 6 in support block 2, upper ejector retainner plate 5, lower thimble
Push rod 7 is connected between plate 6.
Secondary ejecting mechanism, including movable block 8, block 9, mandril 10, spring 11, further include pin 12.
Specifically, movable block 8 is slidably disposed in the sliding slot 51 that 5 periphery of ejector retainner plate opens up, activity laterally to set
The center of block 8 offers a perforative through hole 81, and inclined carrying laterally is formed with from top to bottom at the outside upper angle of movable block 8 tiltedly
Face 82；Block 9 is is vertically arranged, and section is in inverted L-shaped, and block 9 is between core fixing plate 3 and dynamic mould fixing plate 1, block 9
Traversing section 91 be fixed in core fixing plate 3, the vertical section 92 of block 9 is stretched between movable block 8 and support block 2 and extended to down
In the groove 61 that ejector retainner plate 6 opens up, and to be formed with the guiding being adapted with bearing bevel 82 oblique for the madial wall of the vertical section 92 of block 9
Face 93；Mandril 10 is is vertically arranged, and mandril 10 passes through core fixing plate 3, its top is installed in pusher plate 4, bottom and activity
8 top surface of block is in contact；Spring 11 is laterally sets, and between movable block 8 and upper ejector retainner plate 5, one end is connected with movable block 8,
The other end is connected with upper ejector retainner plate 5；Lower ejector retainner plate 6 corresponds to mandril 10 and offers a perforate 62 stretched into for mandril 10；Pin
12 is are vertically arranged, and between movable block 8 and lower ejector retainner plate 6, lower end is installed in lower ejector retainner plate 6, and movable block 8 is stretched into upper end
In the line position slot hole 83 that bottom surface opens up.Pin 12 coordinates with line position slot hole 83 to be used to limit 8 shift length of movable block.
Conducting bar 84 is formed with the side wall of movable block 8, ejector retainner plate 5 offers guide groove in correspondence（It is not shown）, pass through conducting bar 84
Realize and slide with guide groove.On the one hand the stability of movable block 8 is added, on the other hand, moves movable block 8 more smooth, is flowed
Freely.
8 each seamed edge of movable block is formed with chamfering.Chamfering, which is set, avoids movable block from being stuck when moving, and movable block is caused to grind
Damage, is conducive to extend its service life.
The upper end of mandril 10 is fixedly arranged in pusher plate 4 by thread 13.The traversing section 91 of block 9 is fixedly arranged on by thread 13
In core fixing plate 3.Mandril 10, block 9 are fixed by thread respectively, and connection is reliable and firm.
Implementation process：Under original state, as shown in Figure 1, after the completion of injection, spring 11 is relaxation state, the bottom of mandril 10
End is in contact with 8 top surface of movable block；When upper ejector retainner plate 5, lower ejector retainner plate 6 move up, movable block 8 is in its bearing bevel 82 and gear
Move inward under 93 mating reaction of guiding surface of block 9, spring 11 gradually reduces, while movement ejects push piece to mandril 10 upwards
Plate 4, acts on product surface by pusher plate 4 and push rod 7 and releases product, mandril 10 is introduced into the logical of movable block 8 at this time at the same time
In hole 81, as shown in Figure 3；Again as shown in figure 4, when upper ejector retainner plate 5, lower ejector retainner plate 6 continue to move up, movable block 8 is inwardly
Continue to move to, when movable block 8 moves to certain position, mandril 10 enters in the through hole 81 of movable block 8, and pusher plate 4 is no longer pushed up
Go out, upper ejector retainner plate 5, lower ejector retainner plate 6 continue to move up, and mandril 10 is persistently stretched into the perforate 62 of lower ejector retainner plate 6, by push rod 7
Product is ejected.
To sum up, the configuration of the present invention is simple, securely and reliably, can ensure that mould requires ejecting product in sequence, and manufacture
Cost is low, easy to maintain, can greatly save raw material, and the product appearance produced using the mechanism is beautiful, is not in top
Wound, pushes up white phenomenon, is conducive to extend die life.
