Abstract
The utility model relates to a die -casting die structure designs the field, discloses a machined surface has die casting mould of reticulation structure, including mould body (1), be equipped with on the mould shaping plane of mould body corresponding to the die casting machined surface reticulation (2), the reticulation is the parallelogram reticulation, just the reticulation is protruding to be located on the mould shaping plane. This practical invention sets up bellied reticulation on mould shaping plane, can overcome the facing is the technological problem that the gas pocket appears in the product machined surface.
Description
Technical field
This utility model relates to structure of cast die design field, particularly relates to a kind of machined surface and has the die casting mould of reticulate structure
Tool.
Background technology
The machined surface of existing all product die casting blanks is planar structure, and machined surface is thick big structure for one week, and this structure exists
High speed and high pressure fills the poly-liter of temperature in a flash of type, and portion gas is diffused as miniature minute bubbles, and bubble at high temperature expands beyond adding
Spare time measures dimension limit and defines pore, defective after causing blank processing.
In order to solve machined surface to form a difficult problem for pore, existing method is typically to increase allowance and expands pore and miscellaneous
The receiving space of matter, to reduce the formation of bubble, but the method adds overall wall thickness simultaneously, processing surface current when aluminum liquid is filled
To there is no substantially change, effect is not ideal enough.
Utility model content
In order to solve above-mentioned technical problem, this utility model provides a kind of machined surface and has the die-casting mould of reticulate structure.This
Practical invention arranges the reticulate pattern of projection in mould molding plane, it is possible to overcoming plane machining is that Product processing face pore occurs
Technical barrier.
Concrete technical scheme of the present utility model is: a kind of machined surface has the die-casting mould of reticulate structure, including die ontology,
Described die ontology is provided with reticulate pattern corresponding to the mould molding plane of die casting machined surface, and described reticulate pattern is parallelogram reticulate pattern,
And described reticulate pattern is convexly equipped in described mould molding plane.
In order to effectively improve a machined surface pore difficult problem, the present inventor, mainly from the at all increasing swept volume, uses
Network, had both added volume space, by the slight liquid fluidity that changes, excessive gas and impurity can be trapped in net again
In lattice groove.
As preferably, the thickness of described reticulate pattern is 0.35-0.45mm.
As preferably, described reticulate pattern is rectangle reticulate pattern.The structure of rectangle reticulate pattern is easier to stop impurity and minimum gas.
As preferably, described reticulate pattern is square reticulate pattern, and the length of side of described square reticulate pattern is 0.9-1.1mm.
The allowance that this utility model arranges a reticulate pattern and 0.8mm at mould molding plane domain replaces putting down of original 1.2mm
Surface layer；When metal aluminum alloy liquid stream is through each grid, aluminum liquid outermost layer flows in the groove of each grid successively, aluminum liquid before
The impurity comprised and minimum gas is held can be effectively blocked in grid interior without being dissolved into product primary structure tissue easily.
In addition after die casting, the reticulate pattern on surface, Product processing face belongs to machined layer, and gas and impurity that inside incorporates mill i.e. in manufacturing procedure
Can.
Being compared with the prior art, the beneficial effects of the utility model are:
This practical invention arranges the reticulate pattern of projection in mould molding plane, overcomes plane machining and the technical barrier of pore occurs.
Accompanying drawing explanation
Fig. 1 is the top view of die-casting mould in embodiment 1；
Fig. 2 is the side view of die-casting mould in embodiment 1.
Reference is: die ontology 1, reticulate pattern 2.
Detailed description of the invention
Below in conjunction with embodiment, the utility model will be further described.Device, connection involved in this utility model are tied
Structure and method, if without refering in particular to, being device well known in the art, connection structure and method.
Embodiment 1
As a example by the SC63 clutch housing that our company produces.
As shown in Figure 1 and Figure 2, a kind of machined surface has the die-casting mould of reticulate structure, including die ontology 1, described mould
Body is provided with reticulate pattern 2 corresponding to the mould molding plane of die casting machined surface, described reticulate pattern be the length of side be the square net of 1mm
Stricture of vagina, and described reticulate pattern is convexly equipped in described mould molding plane, reticulate pattern thickness is 0.4mm.
Comparative example 1
As a example by the SC63 clutch housing that our company produces.What die ontology corresponded to die casting machined surface is that mould molding is put down
Face, is not provided with reticulate pattern.
Embodiment 2
Embodiment 2 is with the difference of embodiment 1, and the square reticulate pattern length of side of embodiment 2 is 0.9mm, reticulate pattern thickness
For 0.35mm.
Embodiment 3
Embodiment 3 is with the difference of embodiment 1, and the square reticulate pattern length of side of embodiment 2 is 1.1m, and reticulate pattern thickness is
0.45mm。
Embodiment 1 being contrasted with comparative example 1, the porosity that the Product processing face after comparative example 1 die casting produces is 10%～15%
Between, and the finished surface porosity of the product after embodiment 1 die casting controls below 2%.
The above, be only preferred embodiment of the present utility model, not impose any restrictions this utility model, every according to this
Any simple modification, change and the equivalent structure transformation that above example is made by utility model technical spirit, all still falls within this
The protection domain of utility model technical scheme.
