With the promotion oil cylinder being connected on fixed block, the rack is connected and tooth through thread core with Leave out thread mold insert engagement
One end of bar is fixedly connected with fixed block, and the top of the connecting rod is provided with ejection pushing block and Leave out thread pushing block, the ejection pushing block
Leave out thread pushing block is arranged on close to one end of fixed block, the Leave out thread pushing block and the upper surface for ejecting pushing block are inclined-plane, described
The central axis of movable core,return core core puller mold insert is provided with gas circuit, and the top of the gas circuit is provided with air nozzle, the two sides point of the top plate respective link
She You not slanted kicking block.
Specifically, the gradient of the Leave out thread pushing block is less than the gradient of the ejection pushing block.
Specifically, the slanted kicking block includes the first slanted kicking block that ejection is engaged with Leave out thread pushing block and with ejecting pushing block phase
Coordinate the second slanted kicking block of ejection.
Specifically, being additionally provided with support bar between the connecting rod tail end.
The utility model has advantages below and beneficial effect compared with prior art：The utility model is first by interior core
Movable core,return core core puller synchronously blows vacuum to reduce the enclasping force between interiors of products and core, solves when Leave out thread interiors of products has deep-small hole
When, ejection and problem on deformation are difficult during product Leave out thread, the stability of production is improved, product fraction defective is reduced, improves production
Quality.

Embodiment
The utility model is described in further detail with reference to embodiment and accompanying drawing, but implementation of the present utility model
Mode not limited to this.
As shown in Figures 1 to 4, a kind of rear mold Leave out thread ejecting mechanism, including movable core,return core core puller mold insert 1, top plate 2, the and of thread core 3
The Leave out thread mold insert 4 stretched into inside thread core, in addition to be separately positioned on the connecting rod 5 of the both sides of top plate 2, be fixedly connected on connecting rod
Fixed block 6, rack 7 between 5 head ends and the promotion oil cylinder 601 being connected on fixed block 6, the rack 7 pass through thread core 3
It is connected with the Leave out thread mold insert 4 engagement and one end of rack 7 is fixedly connected with fixed block 6, the upper surface of the connecting rod 5 is set
There are ejection pushing block 8 and Leave out thread pushing block 9, the ejection pushing block 8 is arranged on Leave out thread pushing block 9 close to one end of fixed block 6, described
The upper surface of Leave out thread pushing block 9 and ejection pushing block 8 is inclined-plane, and the central axis of the movable core,return core core puller mold insert 1 is provided with gas circuit 10, institute
The top for stating gas circuit 10 is provided with air nozzle 11, and the two sides of the respective link 5 of top plate 2 are respectively equipped with slanted kicking block 12, same during movable core,return core core puller
Step blows anti-vacuum, it is to avoid can not eject and eject the shortcoming of deformation because the enclasping force of thread core 3 is excessive, passes through rack
7 and the synchronous ejecting product of ejection pushing block 8 and the Leave out thread of Leave out thread pushing block 9 of the upper surface of connecting rod 5.
Specifically, the gradient on the inclined-plane of Leave out thread pushing block 9 is less than the gradient on ejection pushing block 8 inclined-plane.Due to taking off spiral shell
Speed during line is slow, and the slope of Leave out thread pushing block 9 is small, and ejection pushing block 8 is used to promote the ejecting product of top plate 1, so as to design
Gradient it is big, the pitchometer of the gear size and product thread of the gradient on the inclined-plane of Leave out thread pushing block 9 on thread core 3
Obtained by calculating, obtained by gradient climb displacement of ejection height and promotion oil cylinder 601 as needed for product on ejection pushing block 8 inclined-plane.
Specifically, the slanted kicking block 12 include be engaged with Leave out thread pushing block 9 ejection the first slanted kicking block 13 and with ejection
Pushing block 8 is engaged the second slanted kicking block 14 of ejection.Phase interaction between the inclined-plane of the Leave out thread pushing block 9 and the second slanted kicking block 14
With, moved up so as to promote Leave out thread push pedal 16 to push top plate 2 to, eject the slanted kicking block 13 of pushing block 7 and first interphase interaction
Promote the motion ejecting product upwards of top plate 2.
Specifically, being additionally provided with support bar 15 between the tail end of connecting rod 5.In order to prevent promoting the drivening rod 5 of oil cylinder 601
Connecting rod 5 swings and uses the reduction life-span when moving forward and backward.
Specific implementation process of the present utility model is as follows：Mould is molded, rear mold core movable core,return core core puller simultaneously air nozzle toward blowing in core
Gas, prevents that vacuum is produced during movable core,return core core puller to be made after deformation of products, rear mold core movable core,return core core puller, promotes oil cylinder 601 to be moved with carry-over bar 7, rack
7 are meshed with Leave out thread mold insert 4, so that mould Leave out thread is carried out, while on Leave out thread pushing block 9 and ejection pushing block 8 and top plate 2
Slanted kicking block 9 is interacted, and is moved up so as to promote Leave out thread push pedal 16 to push top plate 2 to, ejects the oblique top of pushing block 7 and first
The interphase interaction of block 13 promotes top plate 2 to move upwards, ejecting product, so that the ejection of product is completed, due to the contracting of thread core
Breathe out the enclasping force hour of rear product, thus Leave out thread can avoid when synchronously ejecting because thread core due to enclasping force is excessive and nothing
The problem of method ejecting product and ejecting product are deformed.
Above-described embodiment is the utility model preferably embodiment, but embodiment of the present utility model is not by above-mentioned
The limitation of embodiment, it is other it is any without departing from Spirit Essence of the present utility model with made under principle change, modify, replace
Generation, combination, simplification, should be equivalent substitute mode, are included within protection domain of the present utility model.
