Specific embodiment
Fig. 2-5 show related description figure of the present invention；
Receipts formula internal thread demoulding mechanism mould in insert, including the first thread head angle ejector rod 1, the first thread head slider head 2, center
Core pulling latch segment 3, the second thread head angle ejector rod 4, the second thread head slider head 5, the first slide body 6, the second slide body 7, first
Slide body spring 8, the second slide body spring 9, central gathering sill 10, the second tilted footstock 11, the first tilted footstock 12, such as Fig. 2, Fig. 4,
Shown in Fig. 5.
The head of the first thread head angle ejector rod 1, the first thread head slider head 2, central core pulling latch segment 3, the second spiral shell
The head of line head angle ejector rod 4, the second thread head slider head 5 constitute plastic product central, threaded position building core；
The first thread head slider head 2 is installed on the first slide body 6 by screw；Second thread head slider head 5 passes through spiral shell
Nail is installed on the second slide body 7；Respectively by oblique T-slot on first thread head slider head 2, the second thread head slider head 5
It is coupled with central core pulling latch segment 3；The interference of central core pulling latch segment 3 is installed on mold cavity mold insert；
First slide body 6, the second slide body 7 are installed on central gathering sill 10 by T-slot, can be slided along T-slot；The
One slide body 6, the tail end of the second slide body 7 are respectively provided with the first slide body spring 8, the second slide body spring 9；Central gathering sill 10
It is installed on mould template by screw；
The lower end of first thread head angle ejector rod 1 is installed on the first tilted footstock 12, the lower end of the second thread head angle ejector rod 4 is installed on
On second tilted footstock 11, the second tilted footstock 11, the first tilted footstock 12 are installed on die thimble push plate.
Further, illustrated for ease of operation principle of the invention, need the mould structure part pointed out to include die shoe in Fig. 5
Plate 13, thimble push plate 14, thimble cover plate 15, support block 16, core fixing plate 17, core mold insert 18, die cavity mold insert 19, die cavity are fixed
Plate 20, upper clamping plate 21, ejecting limit block 22, release link 23.
During real work, as shown in Fig. 3, Fig. 4, Fig. 5, its motion operation principle is as follows：
1）Sliding block screw thread position core_pulling demoulding mold cavity open after, under the pulling of injection machine push rod, mould dynamic model part with
Cover half part progressively separates, and now, central core pulling latch segment 3 pulls on the first thread head slider head 2, the second spiral shell by T-slot
Line head slider first 5 both to central contraction, so as to drive the first slide body 6, the second slide body 7 in the T-shaped of central gathering sill 10
It is also synchronous to central contraction on groove and under the first slide body of respective push the spring spring 8, the promotion of the second slide body spring 9,
Treat that central core pulling latch segment 3 is kept completely separate with the first thread head slider head 2, the second thread head slider head 5, the first slide body 6,
After both two slide bodies 7 are drawn close, both are respectively S/2 to the distance of central contraction, as shown in figure 4, now, the first thread head is slided
Screw thread position is kept completely separate with product respectively respectively for build 2, the second thread head slider head 5, completes the core pulling of sliding block screw thread position
The demoulding；
2）The demoulding at angle ejector rod head threads position is ejected from the above with product, and under the pulling of injection machine push rod, mould is moved
Mould part continues to separate with cover half part, when the above-mentioned first step action after the completion of, injection machine push rod will promote thimble push plate 14 to
Upper motion, thus promote the first thread head angle ejector rod 1, the second thread head angle ejector rod 4 along the gathering sill in core mold insert 18 will produce
Product are ejected, and product will come off from the head of the first thread head angle ejector rod 1, the second thread head angle ejector rod 4, so as to complete whole product
The screw thread demoulding with ejection；For prevent the first thread head angle ejector rod 1, the second thread head angle ejector rod 4 ejection finally when both
Head produces interference, sets limitation ejection height H by the ejecting limit block 22 being installed on thimble cover plate 15 to limit the first spiral shell
The ejection height of line head angle ejector rod 1, the second thread head angle ejector rod 4, the reliability not interfered during with really both ejections, such as schemes
Shown in 5.
3）Reset mould close, under the promotion of injection machine push rod, mould dynamic model part will progressively close to cover half part,
Mould will be closed, and now, the release link 23 in ejection state first encounters impression bolster 20, in withstanding for impression bolster 20
Under, the first thread head angle ejector rod 1, the second thread head angle ejector rod 4 will reset in advance；Treat that the central lower end of core pulling latch segment 3 encounters
After the T-slot of both one thread head slider head 2, the second thread head slider head 5 and insertion, both will be produced with one to the left, one
The partial pressure of individual horizontal direction dorsad to the right, so that, overcome the first slide body spring 8, the second slide body spring 9 to suppress
Resistance, reset is pushed back by the first thread head slider head 2 and the first slide body 6, the second thread head slider head 5 and the second slide body 7,
Then, mould is closed completely, waits next injection cycle to start.
Specific embodiment described herein is only the technology neck belonging to the present invention to the present invention spiritual explanation for example
The technical staff in domain can be made various modifications or supplement to described specific embodiment or be replaced using similar mode
Generation, but without departing from spirit of the invention or surmount scope defined in appended claims.
