Abstract
The invention discloses a kind of the anti-jamming to inserting core structure, including the first sliding block, the second sliding block, first sliding block and the perpendicular arrangement of the second sliding block and close contact of die casting, it is characterised in that：It is provided with core on first sliding block, insert is provided on second sliding block, the core passes perpendicularly through the insert, multiple annular oil grooves are provided on the core, the multiple annular oil groove is located in the duct in the insert, and somewhat cold pipe is arranged inside the core in the axial direction.Beneficial effects of the present invention include：By changing the structure of core, reduce core caused by thermal expansion, the factors such as small―gap suture pull, stuck phenomenon, production efficiency is greatly improved, increases the service life of core.
Description
Technical field
The present invention relates to die casting mold fields, and in particular to a kind of die casting it is anti-jamming to inserting core structure.
Background technology
Die-casting process refers to will will be in the quick injection to mold of the metallic solution that dissolved and cooled and solidified by high pressure mode
A kind of manufacturing process for making it shape, 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 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 thermally expanding, the reasons such as gap is small often will appear drawing in core withdrawing
Phenomena such as hindering, is stuck, seriously affects production efficiency.
Invention content
Shortcoming in for the above-mentioned prior art, the present invention provide a kind of the anti-jamming to inserting core knot of die casting
Structure, it is simple in structure, effectively reduce the stuck phenomenon of core.
In order to achieve the above object, present invention employs following technical schemes：
A kind of die casting it is anti-jamming to inserting 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：Core, second sliding block are provided on first sliding block
On be provided with insert, the core passes perpendicularly through the insert, and multiple annular oil grooves, the multiple ring are provided on the core
Shape oil groove is located in the duct in the insert, and somewhat cold pipe is arranged inside the core in the axial direction.
Further, the multiple annular oil groove is arranged along the axis direction interval of the 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, described core one end is provided with the point cooling system for being connected to the cold pipe of point.
Beneficial effects of the present invention include：By changing the structure of core, caused by reducing the factors such as thermal expansion, small―gap suture
Core pulls, stuck phenomenon, and production efficiency is greatly improved, increases the service life of core.
Description of the drawings
Fig. 1 is the structural schematic diagram of invention；
Fig. 2 is the sectional view of A-A in Fig. 1；
Fig. 3 is the partial enlarged view of B in Fig. 2.
Specific implementation mode
With reference to specific embodiment and attached drawing, present invention be described in more detail.
A kind of die casting as shown in Figures 1 to 3 it is anti-jamming to inserting core structure, including the first sliding block 1, the second sliding block
2, first sliding block, 1 and second sliding block, 2 perpendicular arrangement and close contact.It is provided with core 3 on first sliding block 1；
It is provided with insert 4 on second sliding block 2；The core 3 extends vertically through the insert 4, and the core 3 can be in the edge
It is axially moved in the duct of block 4.There are two annular oil grooves 5 for setting on the core 3, and described two annular oil grooves 5 are along described
The axis direction interval of core 3 is arranged, and two annular oil grooves 5 are located in the duct in the insert 4.In the core 3
Somewhat cold pipe 6 is arranged in portion in the axial direction.
The annular oil groove 5 is that section is semicircular oil groove, and is provided with kollag in the oil groove.The solid moistens
Lubrication prescription can be high temperature-resistant grease or graphitic lubricant, and main function is rubbing of reducing that core 3 moves in the duct of insert 4
Wipe power.
The point cooling system for being connected to the cold pipe of the point 6 is provided in 3 one end of the core.By cooling system and put cold pipe 6
Interior coolant liquid recycles to play the role of cooling to core 3, and the further thermal expansion for reducing core 3 prevents core 3 from inlaying
Stuck phenomenon occurs when being moved in the duct of block 4.Core 3 also passes through nitrogen titanium aluminide and is surface-treated simultaneously, improves case hardness, subtracts
It pulls less, increases the service life of core 3.
It is provided for the embodiments of the invention technical solution above to be described in detail, specific case used herein
The principle and embodiment of the embodiment of the present invention are expounded, the explanation of above example is only applicable to help to understand this
The principle of inventive embodiments；Meanwhile for those of ordinary skill in the art, embodiment according to the present invention, in specific embodiment party
There will be changes in formula and application range, in conclusion the content of the present specification should not be construed as limiting the invention.
