Abstract
The utility model discloses a kind of the anti-jamming to slotting core structure of die casting, including the first sliding block, the second sliding block, first sliding block and the perpendicular arrangement of the second sliding block and close contact, it is characterized by: being provided with type core on first sliding block, insert is provided on second sliding block, the type core passes perpendicularly through the insert, multiple annular oil grooves are provided on the type core, the multiple annular oil groove is located in the duct in the insert, and somewhat cold pipe is arranged in the type core inner in the axial direction.The beneficial effects of the utility model include: by the structure of change type core, reduce type core caused by the factors such as thermal expansion, small―gap suture pull, stuck phenomenon, production efficiency is greatly improved, increases the service life of type core.
Description
Technical field
The utility model relates to die casting mold fields, and in particular to a kind of die casting it is anti-jamming to slotting core structure.
Background technique
Die-casting process refer to by by high pressure mode by the quick injection of the metallic solution dissolved into mold, and cooled and solidified
A kind of manufacturing process for shaping it, wherein being widely used in foundry engieering.
Many casting need the mold using band to slotting core structure in casting, and primary structure includes multiple on mold
Sliding block, the type core on one of sliding block need to be punctured on another sliding block, and the type of casting is combined by the group of multiple sliding blocks
Chamber, but in actual use often because of thermal expansion, the reasons such as gap is small often will appear drawing in type core withdrawing
Phenomena such as hurting, is stuck, seriously affects production efficiency.
Summary of the invention
Place in view of the deficiency of the prior art, the utility model provide a kind of the anti-jamming to slotting type of die casting
Cored structure, structure is simple, effectively reduces the stuck phenomenon of type core.
In order to achieve the above object, the utility model uses following technical scheme:
A kind of die casting it is anti-jamming to slotting core structure, including the first sliding block, the second sliding block, first sliding block and
The perpendicular arrangement of second sliding block and close contact, it is characterised in that: type core, second sliding block are provided on first sliding block
On be provided with insert, the type core passes perpendicularly through the insert, multiple annular oil grooves, the multiple ring is provided on the type core
Shape oil groove is located in the duct in the insert, and somewhat cold pipe is arranged in the type core inner in the axial direction.
Further, the multiple annular oil groove is arranged along the axis direction interval of the type core.
Further, it is semicircular oil groove that the multiple annular oil groove, which is section, and solid profit is provided in the oil groove
Lubrication prescription.
Further, type core one end is provided with the point cooling system for being connected to the cold pipe of point.
The beneficial effects of the utility model include: to reduce the factors such as thermal expansion, small―gap suture by the structure of change type core and draw
Rise type core pull, stuck phenomenon, production efficiency is greatly improved, increases the service life of type core.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of utility model；
Fig. 2 is the cross-sectional view of A-A in Fig. 1；
Fig. 3 is the partial enlarged view of B in Fig. 2.
Specific embodiment
Combined with specific embodiments below and attached drawing is further described the utility model.
A kind of die casting as shown in Figures 1 to 3 it is anti-jamming to slotting core structure, including the first sliding block 1, the second sliding block
2, first sliding block 1 and the perpendicular arrangement of the second sliding block 2 and close contact.Type core 3 is provided on first sliding block 1；
Insert 4 is provided on second sliding block 2；The type core 3 extends vertically through the insert 4, and the type core 3 can be in the edge
It is axially moved in the duct of block 4.Setting is there are two annular oil groove 5 on the type core 3, and described two annular oil grooves 5 are along described
The axis direction interval of type core 3 is arranged, and two annular oil grooves 5 are located in the duct in the insert 4.In the type core 3
Somewhat cold pipe 6 is arranged in portion in the axial direction.
It is semicircular oil groove that the annular oil groove 5, which is section, and is provided with solid lubricant in the oil groove.Solid profit
Lubrication prescription can be high temperature-resistant grease or graphitic lubricant, and main function is the rubbing of moving in the duct of insert 4 of reduced type core 3
Wipe power.
The point cooling system for being connected to the cold pipe 6 of point is provided in described 3 one end of type core.Pass through a cooling system and the cold pipe 6 of point
Interior coolant liquid recycles to play the role of cooling to type core 3, and the thermal expansion of further reduced type core 3 prevents type core 3 from inlaying
Stuck phenomenon occurs when moving in the duct of block 4.Simultaneous type core 3 is also surface-treated by nitrogen titanium aluminide, is improved surface hardness, is subtracted
It pulls less, the service life of increment type core 3.
Technical solution provided by the utility model embodiment is described in detail above, it is used herein specifically
A example is expounded the principle and embodiment of the utility model embodiment, and the explanation of above embodiments is only applicable to help
Assistant solves the principle of the utility model embodiment；At the same time, for those skilled in the art is implemented according to the utility model
Example, there will be changes in terms of specific embodiments and scope of application, in conclusion the content of the present specification should not be construed as
Limitations of the present invention.
