Abstract
The utility model discloses a kind of pre- ejecting mechanism of cover half, fixed die insert is embedded on cover half and dynamic model respectively with moving die insert, fixed die insert is corresponding with moving die insert to fit to form die joint, one end of pre- push rod is on cover half, spring is provided between pre- push rod and cover half, and the other end of pre- push rod is passed from die joint through fixed die insert and is close to moving die insert.This utility model combines the demolding structure of pre- push rod using spring, makes pre- push rod be always maintained at release trend in casting process.Eject when the moment of mould die sinking, pre- push rod, the foundry goods being close on fixed die insert is ejected so as to depart from fixed die insert, realize the pre- ejection of foundry goods.This utility model simple structure, stable and reliable in work, effectively reduce foundry goods sticking to mould number of times, improve production efficiency.
Description
Technical field
This utility model is related to casting mould part, the pre- ejecting mechanism of particularly a kind of cover half.
Background technology
During Die-Casting, due to material behavior, mold surface temperature etc. reason, hold when foundry goods is molded
The phenomenon of sticking to mould is also easy to produce, especially some positions of some foundry goods are thiner, is more prone to cause foundry goods sticking to mould, causes to cast
There is modification in part, damaging even cannot dropping situations.
Utility model content
This utility model aim to provide a kind of reduce foundry goods sticking to mould number of times, the pre- ejecting mechanism of the cover half of improve production efficiency.
For achieving the above object, the technical scheme adopted by this utility model is：A kind of pre- ejecting mechanism of cover half, cover half are inlayed
Block is embedded on cover half and dynamic model, wherein respectively with moving die insert：Fixed die insert is corresponding with moving die insert to fit to form die joint,
One end of pre- push rod is provided with spring between pre- push rod and cover half on cover half, and the other end of pre- push rod is inlayed through cover half
Block is passed from die joint and is close to moving die insert.
The pre- ejecting mechanism of above-mentioned cover half, is provided with cushion block on described cover half, after the cushion block is correspondingly arranged at pre- push rod
End, spring are located between pre- push rod and cushion block.
The pre- ejecting mechanism of above-mentioned cover half, is provided with cushion block, on described pre- push rod after the cushion block is correspondingly arranged at pre- push rod
End, spring are located between pre- push rod and cushion block.
The pre- ejecting mechanism of above-mentioned cover half, is provided with location hole on described cushion block, and the location hole is socket-connected with pre- push rod.
The pre- ejecting mechanism of above-mentioned cover half, is disk spring in described spring.
The pre- ejecting mechanism of above-mentioned cover half, described cushion block are fixedly connected with cover half by screw.
, using after said structure, in idle state, pre- push rod is under the force of a spring, spacing for mould for this utility model
Boss clinching prevents pre- push rod abjection on cover half.During work, mold clamp, dynamic model drive determining on moving die insert and cover half
Mould insert is fitted, and now, pre- push rod back pressure, moving die insert, fixed die insert and pre- push rod three are constituted die cavity by moving die insert.
After solution enters die cavity sizing coagulation forming, dynamic model drives moving die insert and the fixed die insert on cover half point
From, now, pre- push rod loses the compression of moving die insert, spring active force under eject, foundry goods is pushed away fixed die insert, so as to
Reach and product pre-release is ejected, reduce foundry goods sticking to mould number of times, the purpose of improve production efficiency.
Description of the drawings
With reference to the accompanying drawings and detailed description this utility model is described in further detail：
Fig. 1 is this utility model matched moulds view.
Fig. 2 is this utility model die opening state schematic diagram.
Fig. 3 is this utility model overall schematic.
In figure：1 is cover half, and 11 is fixed die insert, and 2 is dynamic model, and 21 is moving die insert, and 3 is pre- push rod, and 4 is spring, and 5 are
Cushion block, 6 is foundry goods.
Specific embodiment
As shown in Figures 1 to 3, the pre- ejecting mechanism of a kind of cover half, fixed die insert 11 are embedded in cover half 1 respectively with moving die insert 21
On dynamic model 2, the laminating corresponding with moving die insert 21 of fixed die insert 11 forms die joint, and one end of pre- push rod 3 is arranged on cover half 1
On, spring 4 is provided between pre- push rod 3 and cover half, the other end of pre- push rod 3 is passed through fixed die insert 11 from die joint and tight
Patch moving die insert 21；Cover half 1 is provided with cushion block 5, and the cushion block 5 is correspondingly arranged at the rear end of pre- push rod 3, spring 4 be located at pre- push rod 3 with
And between cushion block 5；Pre- push rod 3 is provided with cushion block 5, and the cushion block 5 is correspondingly arranged at 3 rear end of pre- push rod, spring 4 be located at pre- push rod 3 with
Between cushion block 5；Cushion block 5 is provided with location hole 51, and the location hole 51 is socket-connected with pre- push rod 3；Spring 4 is disk spring；Cushion block 5
It is fixedly connected with cover half 1 by screw.
Operation principle when this utility model is embodied as：Mould in idle state, effect of the pre- push rod 3 in spring 4
Under power, positive stop lug boss clinching prevents pre- push rod 3 from deviating from cover half 1.During work, mold clamp, dynamic model 2 drive moving die insert
21 are fitted with the fixed die insert 11 on cover half 1, and now, moving die insert 21 is by 3 back pressure of pre- push rod, moving die insert 21, fixed die insert
11 and 3 three of pre- push rod constitute die cavity.
After solution enters die cavity sizing coagulation forming, dynamic model 2 drives moving die insert 21 and the fixed die insert on cover half 1
11 separate, and now, pre- push rod 3 loses the compression of moving die insert 21, spring 4 active force under eject, foundry goods 6 is pushed away cover half
Product pre-release is ejected by insert 11 so as to reach, and reduces foundry goods sticking to mould number of times, the purpose of improve production efficiency.
The above is preferred implementation of the present utility model, can not be limited with this certainly this utility model it
Interest field, it is noted that for those skilled in the art, is carried out to the technical solution of the utility model
Modification or equivalent, without departure from the protection domain of technical solutions of the utility model.
