The pilot hole and centre hole of upper and lower surface are penetrated through, reset guide bar is located in pilot hole, and runner ejector pin is located in centre hole, described
Centre hole is located at runner bottom, and the jacking block lower part is connected with drag hook, and ejector retainner plate bottom surface is caught in drag hook bottom.
Preferably, the shape of the drag hook is "L" shaped.
Preferably, the ejector retainner plate is formed by connecting for superposition above and below upper and lower ejector retainner plate with screw, the upper ejector retainner plate bottom surface
Stepped hole is provided with, the runner ejector pin and reset guide bar are fixed on upper and lower ejector retainner plate after passing through upper ejector retainner plate from lower to upper
Between.
Preferably, the upper thimble plate top surface is provided with stepped hole, is provided at the stepped hole at corresponding lower ejector retainner plate
Through hole, nitrogen gas spring is inserted into from lower to upper in the through hole of lower ejector retainner plate and the screw spiral shell by being arranged at upper thimble board step hole
Line connection is fixed.
The present invention is compact-sized ingenious, is used conveniently and safely reliably, by runner design in jacking block, reduces mould volume,
It does not influence normally to use simultaneously, is suitble to some certain modulis tool, a kind of new side has been started for the design of injection mould runner

Specific embodiment
Below in conjunction with the accompanying drawings, the present invention is described in further detail.
As shown in Figures 1 to 6, the present invention provides a kind of mold jacking block inner flow passage Dan Zhen mechanisms, including runner 1 and jacking block
2, the runner 1 is arranged on the top of jacking block 2, and 2 bottom of jacking block is connected with mandril 3,2 lower surface of jacking block at the runner 1
Runner ejecting mechanism 4 is provided with, the runner ejecting mechanism 4 includes runner ejector pin 5, reset guide bar 6, ejector retainner plate 7 and nitrogen
Spring 8, the perforation pilot hole 9 of upper and lower surface is provided on the jacking block 2 and centre hole 10, reset guide bar 6 are located at pilot hole 9
Interior, the either flush of 6 top surface of reset guide bar and jacking block 2, runner ejector pin 5 is located in centre hole 10, and the centre hole 10 is located at
1 bottom of runner, 2 lower part of jacking block are connected with drag hook 11, and 7 bottom surface of ejector retainner plate is caught in 11 bottom of drag hook.
Preferably, the shape of the drag hook 11 is "L" shaped.
Preferably, the ejector retainner plate 7 is upper and lower ejector retainner plate 12, about 13 superpositions are formed by connecting with screw, the upper thimble
12 bottom surface of plate is provided with stepped hole, and the runner ejector pin 5 and reset guide bar 6 are fixed on after passing through upper ejector retainner plate 12 from lower to upper
Between upper and lower ejector retainner plate 12,13.
Preferably, 12 top surface of upper ejector retainner plate is provided with stepped hole, is set at the stepped hole at corresponding lower ejector retainner plate 13
Through hole is equipped with, nitrogen gas spring 8 is inserted into the through hole of lower ejector retainner plate 13 and from lower to upper by being arranged on upper 12 stepped hole of ejector retainner plate
The screw thread connection at place is fixed.
In use, after injection, mandril 3 pushes up jacking block 2 and ejects, and the drag hook 11 on jacking block 2 drives upper and lower top
Needle plate 12,13 is synchronously moved upwards together, it is necessary to push up upper and lower top by nitrogen gas spring 8 when ejecting the raw material in runner 1
Needle plate 12,13 moves upwards, and upper and lower ejector retainner plate 12,13 promotes runner ejector pin 5 and reset guide bar 6 to move upwards, runner ejector pin
5 eject the raw material in runner 1 along 10 upward sliding of centre hole, and reset guide bar 6 is led along the stretching of 9 upward sliding of pilot hole
It into hole 9, realizes and ejects the raw material in 2 inner flow passage 1 of jacking block, stream is removed in convenient injection molding work next time after ejection
Upper and lower ejector retainner plate 12,13 replys under the action of 8 its own resilient of nitrogen gas spring move downward again after raw material in road 1, runner ejector pin
5 and reset guide bar 6 move downward reset, even if nitrogen gas spring 8 can not reset immediately, due to 6 top surface of reset guide bar with top
The either flush of block 2, when molding, the reset guide bar 6 on jacking block 2 can move downward under the extruding of mold retracts top
It realizes and resets in block 2, realize the reset function of runner ejecting mechanism 4, whole work process is reliable and stable.
The above is only the better embodiment of the present invention, not makees limitation in any form to invention, it is every according to
According to the technical principle of the present invention to any simple modification made for any of the above embodiments, equivalent variations or modification, the present invention is still fallen within
In the range of technical solution.
