Fig. 4 is the structural schematic diagram of state after second of ejection of the present invention.
Specific implementation mode
Present invention will be further explained below with reference to the attached drawings and specific embodiments.As shown in Figs 1-4, wherein in order to more
Clearly show that the structure of the present invention, Fig. 1 have done 180 ° of rotations of standing upside down relative to Fig. 2-4.The concealed Double-ejection of injection mold
Mechanism includes the ejector retainner plate being made of upper ejector retainner plate and lower ejector retainner plate, sliding slot is formed in the lower ejector retainner plate of the ejector retainner plate, described
It is provided with sliding lock block 3 in sliding slot, jogger hole 31 is formed in the sliding lock block 3, runs through in the jogger hole 31 and is equipped with mandril
1,1 bottom of the mandril is fixed with limited screw 5, and stop collar 4 is cased on the limited screw 5, and the section of the stop collar 4 is in
It is similar to handstand U-shaped, the top of the stop collar 4 is formed with screw hole, and the bottom of the stop collar 4 is fixed on the bottom plate of mold
On, the bar portion 51 of the limited screw 5 is fixed on 1 bottom of the mandril, the cap of the limited screw 5 after the screw hole
First 52 are located in the stop collar 4, and frieze rail 52 is slightly larger than the screw hole at the top of stop collar 4, limited screw 5 in ejection process
It can be slided in stop collar 4, until cap head 52 is stuck at 4 top of stop collar.Card slot 11, institute are also formed on the mandril 1
Card slot inclined-plane 111 is made in the cell wall for stating card slot 11, and the corresponding position of the jogger hole 31 is formed with and 111 phase of card slot inclined-plane
The mandril inclined-plane 311 mutually coordinated, the jogger hole 31 stick into card slot 11.When the sliding lock block 3 of Fig. 4 states is resetted,
Under being engaged on card slot inclined-plane 111 and mandril inclined-plane 311, jogger hole 31 is easier to slip into card slot 11.The mould
Solution closing piece 7 is installed on the support block of tool, unlock inclined-plane 71, pair of the sliding lock block 3 is made in the lower part of the solution closing piece 7
It should partly be formed with and spring 8, institute are housed with 71 mutually matched closing piece inclined-plane 31 of the unlock inclined-plane, 3 side of the sliding lock block
State spring 8 both ends be separately fixed at the lower ejector retainner plate sliding slot inner wall and the sliding lock block 3 side.
In above-mentioned technical proposal：The sliding lock block 3 is in convex shape, and the both sides of 3 boss of the sliding lock block are installed
There are sliding press strip 6, the both sides of the sliding press strip 6 and 3 boss of the sliding lock block to coordinate by I-shaped block and I-shaped slot
Installation.Specifically cooperation mounting means can be for it：3 boss both sides of sliding lock block are formed with I-shaped block, two sliding press strips, 6 inside
It is formed with I-shaped slot, I-shaped block slides in I-shaped slot；Can also be：3 boss both sides of sliding lock block are formed with I-shaped slot, and two slide
6 inside of dynamic pressure item is formed with I-shaped block, and I-shaped block slides in I-shaped slot.The wherein concrete structure of I-shaped block and I-shaped slot is similar to
Inner slide in Chinese patent CN201110313653.1 disclosures and oblique I-shaped slot.The sliding press strip 6 is fixed on lower top
On needle plate, and guiding role is played to sliding lock block 3.
In above-mentioned technical proposal：Top stem casing 2 is also cased on the mandril 1, the lower part of the top stem casing 2 is fixed on thimble
In plate, the top of the top stem casing 2 is run through and stretches out the upper ejector retainner plate, and the top stem casing 2 plays guiding role to mandril 1.
The course of work of the present invention is as follows, starts to do ejection action after injection mold die sinking, ejector retainner plate drives sliding press strip
6, sliding block closing piece 3 and top stem casing 2 move upwardly together, simultaneously because sliding lock block 3 is in the lock state with mandril 1, such as Fig. 1 institutes
Show, mandril 1 drives limited screw 5 also to move upwardly together in the above process.After ejection a distance on sliding lock block 3 and support block
Solution closing piece 7 start to contact, under the action of unlocking inclined-plane 71 and closing piece inclined-plane 32, sliding lock block 3 is in the process moved upwards
In it is horizontal in sliding slot simultaneously slide to the left, should during spring 8 compressed.Until move to shown in Fig. 3, jogger hole 31 at this time
The card slot 11 being detached from mandril 1 realizes the unlock of sliding lock block 3 and mandril 1, while mandril 1 is because limited screw 5 is limited set
4 limit and stuck and stop motion, are so far first time ejection process.For the first time ejection can by select 5 length of limited screw come
Control ejection distance.
Second of ejection：Ejector retainner plate drives sliding lock block 3, sliding press strip 6 and top stem casing 2 to continue to do ejection movement, this mistake
Cheng Zhong, mandril 1 is slack.The ejection distance of second of ejection movement freely adjusts according to actual needs.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without
It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution should all be fallen within the scope of protection of the present invention.
