In this present embodiment, secondary ejection structure of the invention is applied in mold, and the mold includes bottom plate
10, lower liftout plate 11, upper ejector plate 12, male template 13, caster 14, male die core 15 and mother module core 16, the Double-ejection knot
Structure includes:
Limited block 100 is fixed on upper ejector plate 12, and 100 upper surface of limited block has with 13 lower surface of male template
First stroke distance, in this present embodiment, first stroke distance are 30mm；
Angled slide block 200 is rotated, is set in the groove 17 that bottom plate 10 opens up in rotary manner, the rotation angled slide block
200 have first rotating arm 201 at an angle to each other and the second rotating arm 202；
First thimble 300, one end are set on first rotating arm 201, and other end upper surface has with 13 lower surface of male template
Second stroke distance, in this present embodiment, the second stroke distance be 24mm, the second stroke distance be less than first stroke away from
From 300 preferential contact male template 13 of the first thimble when guaranteeing to be opened；
Second thimble 400, one end are set on the second rotating arm 202, and the other end runs through upper ejector plate 12, male template 13 and public affairs
Product 20 after molding is headed on after mode 15, which chooses and head at the easy disengaging of product 20；
Several third thimbles 500, one end are fixed on lower liftout plate 11, and the other end runs through upper ejector plate 12, male template 13
And product 20 after molding is headed on after male die core 15, which is common thimble.
Wherein, 200 middle position of rotation angled slide block is equipped with rotary shaft 203, and 203 both ends of rotary shaft are fixed on
In lower liftout plate 11, the rotation angled slide block 200 is rotated along the rotary shaft 203, can more be accurately controlled spinning movement.When
It so, can also be in the middle position protrusion setting rotary shaft 203 of rotation 200 two sides of angled slide block, in lower ejection in other embodiments
Receiving hole is set in plate 11, rotary shaft 203 is set in receiving hole.
Wherein, fixed block 204 is equipped in the groove 17, the rotary shaft 203 is set in fixed block 204, and described first
Rotating arm 201 and the second rotating arm 202 are stretched out from fixed block 204, and the fixed block 204 is equipped with rotation angled slide block 200
Movable space is further accurately controlled the spinning movement of rotation angled slide block 200.
Wherein, the secondary ejection structure also has elastic element 600 and pressing plate 700, and elastic element 600 is placed on the second top
The outer rim of 400 one end of needle, pressing plate 700, which is fixed in upper ejector plate 12, is pressing against the elastic element 600, second thimble 400
The other end passed through from pressing plate 700.Wherein, the elastic element 600 is spring, when mold clamping state, the elasticity
Element 600 is in extended state.After mold is opened completely, elastic element 600 is in confined state, when molding again, in institute
Under the elastic force effect for stating elastic element 600, the second thimble 400 and rotation 200 return of angled slide block are assisted.
Referring to shown in Fig. 2, the molding of product 20 is completed, and after mold die sinking, upper ejector plate 12 and lower liftout plate 11 exist
The lower ejection upwards of the ejection effect of mold, each third thimble 500 are normal under the action of upper ejector plate 12 and lower liftout plate 11
Product 20 is ejected, the first thimble 300 and the second thimble 400 move upwards simultaneously, and rotation angled slide block 200 is failure to actuate, until upper
Liftout plate 12, lower liftout plate 11, the first thimble 300, the second thimble 400 and third thimble 500 move up to second stroke away from
From 24mm, the first thimble 300 contacts male template 13 at this time, completes to eject for the first time.
Referring to shown in Fig. 3, the first thimble 300 has contacted male template 13 and has completed after ejecting for the first time, in mold
Under ejection effect, due to also having stroke distances 6mm between limited block 100 and male template 13, (first stroke distance subtracts the second row
Journey distance), upper ejector plate 12, lower liftout plate 11 continue up ejection 6mm distance, meanwhile, the first thimble 300 is in male template 13
Active force under move downward, rotation angled slide block 200 first rotating arm 201 move down, rotate angled slide block 200 along rotation
Axis 203 rotates, and the second rotating arm 202 moves up, and the second thimble 400 is driven to move upwards, and compares the second thimble 400
A distance is ejected in third thimble more than 500, so that product 20 and third thimble 500 be made to be detached from, is conducive to taking for product 20
Under.
In conclusion secondary ejection structure of the invention can easily remove product 20 from thimble, avoid
Product 20 presss from both sides thimble.
