Abstract
The utility model provides a kind of structure of cast die using taper pin twice core pulling, including dynamic model, quiet mould, sliding block is respectively arranged between dynamic model and quiet mould, the dynamic model, sliding block, through hole is respectively equipped with quiet mould, through hole is obliquely installed, dynamic model, sliding block, the through hole on quiet mould are connected to become an inclined passage, and taper pin is interspersed with passage.Using the structure of cast die described in the utility model using taper pin twice core pulling, twice core pulling is achieved that using a taper pin section in mould, reduces core pulling device quantity, reduces die manufacturing cost.
Description
Technical field
It the utility model is related to a kind of mould, especially a kind of structure of cast die using taper pin twice core pulling.
Background technology
At present, in Die Casting, for some thin-section castings, to avoid core pulling from being deformed, core pulling twice can be used, i.e.,
After a part of package power of first time core pulling removal, second of core pulling is remake.Two sets of core-pulling mechanisms are needed to use during mold design
It can realize, not only increase mold design difficulty, also increase manufacturing expense.
The content of the invention
The purpose of this utility model is to provide a kind of structure of cast die using taper pin twice core pulling, only with one tiltedly
Pin, twice core pulling is can be achieved with, reduce core pulling device quantity.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is as follows：It is a kind of using taper pin twice core pulling
Structure of cast die, including dynamic model, quiet mould, sliding block is respectively arranged between dynamic model and quiet mould, it is characterised in that：The dynamic model,
Be respectively equipped with through hole on sliding block, quiet mould, through hole is obliquely installed, dynamic model, sliding block, the through hole on quiet mould be connected to become one it is inclined
Passage, taper pin is interspersed with passage.
Improvement to above-mentioned technical proposal：Sliding block on the inside of the dynamic model is bigger than the sliding block on the inside of quiet mould.
Beneficial effect：
Using the structure of cast die described in the utility model using taper pin twice core pulling, a taper pin is used in mould
Section is achieved that twice core pulling, reduces core pulling device quantity, reduces die manufacturing cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model as shown in Figure 1 use taper pin twice core pulling structure of cast die, including dynamic model 1, quiet mould 2,
Casting 3, is respectively arranged with sliding block 4,5 between dynamic model 1 and quiet mould 2, the dynamic model 1, sliding block 4,5, be respectively equipped with through hole on quiet mould 2
6, through hole 6 is obliquely installed, and dynamic model 1, sliding block 4,5, the through hole 6 on quiet mould 2 are connected to become an inclined passage, intert in passage
There is taper pin 7.
The utility model uses large and small two sliding blocks, and two sliding blocks are combined, and shares a taper pin, wherein greatly
Sliding block uses time-lapse core pulling.During die sinking, taper pin drives the core pulling of small-sized core sliding block elder generation, after small-sized core removal package power, taper pin band again
Dynamic large and small sliding block is synchronously extracted out.
Claims (2)
1. a kind of structure of cast die using taper pin twice core pulling, including dynamic model, quiet mould, are set respectively between dynamic model and quiet mould
There is sliding block, it is characterised in that：The dynamic model, sliding block, through hole is respectively equipped with quiet mould, through hole is obliquely installed, dynamic model, sliding block, quiet
Through hole on mould is connected to become an inclined passage, and taper pin is interspersed with passage.
A kind of 2. structure of cast die using taper pin twice core pulling according to claim 1, it is characterised in that：It is described dynamic
Sliding block on the inside of mould is bigger than the sliding block on the inside of quiet mould.
