Abstract
The invention discloses a kind of cast cleaning pore structure, and it is used for the sand removal of casting, and cast cleaning pore structure is broken including sand cleaning hole, spot face, hole tail plane and at least three cuts groove.Sand cleaning hole is arranged on casting；Spot face is located at the outside of sand cleaning hole；Hole tail plane is located at the inner side of sand cleaning hole；At least three it is disconnected cut groove and be located at hole tail plane and connected with sand cleaning hole, and be uniformly distributed along the center of sand cleaning hole.The cast cleaning pore structure of the present invention can advantageously reduce cleaning difficulty and disposal costs that core cavity iron is cut, and can improve the cleannes of core cavity, ensure the product quality of casting.
Description
Technical field
The present invention relates to Machine Design and manufacturing field, more particularly to a kind of cast cleaning pore structure.
Background technology
In mechanical engineering field, numerous parts are produced using casting technique, for box casting or include inner chamber
Casting, it is often necessary to design sand removal pore structure, cleared again from sand cleaning hole by the molding sand of inner chamber after casting, recycle
Sand cleaning hole is processed by mach method, is recycled to block after finishing and is blocked sand cleaning hole, you can it is complete to obtain casting
Inner-cavity structure.
Traditional cast cleaning pore structure, has the disadvantage that：(1) in process, hole tail end easily produces iron and cuts group
Drop to inside core cavity, because iron is cut, group is larger, and sand cleaning hole is relative again smaller, therefore the iron inside core cavity that drops
The group's of cutting cleaning difficulty is very big, and the manual resource of scale removal process input is more, and disposal costs are higher.(2) in addition, iron cut group be also possible to
It is stuck in securely inside the corner of inner chamber, and the inspection of scale removal process corner depths is more difficult, iron is cut group and may slipped in inner chamber
Inside corner, so as to cause cleaning not thorough, the cleannes of core cavity are have impact on, have impact on the product quality of casting.How
Overcome disadvantages mentioned above, improve sand removal efficiency, it is for this area urgent problem to be solved to mitigate hand labor intensity.
The information for being disclosed in the background section is merely intended to understanding of the increase to the general background of the present invention, without answering
It has been the prior art well known to persons skilled in the art when being considered as recognizing or implying the information structure in any form.
The content of the invention
It is an object of the invention to provide a kind of cast cleaning pore structure, so as to overcome in the prior art due to iron cut group compared with
Greatly, sand cleaning hole is relative again smaller, therefore to cut a cleaning difficulty very big for the iron inside core cavity that drops, scale removal process input
Manual resource is more, and disposal costs are higher and iron is cut group and may slipped inside the corner of inner chamber, so as to cause cleaning not thorough
Bottom, the cleannes of core cavity are have impact on, the shortcomings that have impact on the product quality of casting.
To achieve the above object, the invention provides a kind of cast cleaning pore structure, it is used for the sand removal of casting, and casting is clear
Sand hole structure is broken including sand cleaning hole, spot face, hole tail plane and at least three cuts groove.Sand cleaning hole is arranged on casting；Hole
Mouth plane is located at the outside of sand cleaning hole；Hole tail plane is located at the inner side of sand cleaning hole；At least three it is disconnected cut groove be located at hole tail plane and
Connect with sand cleaning hole, and be uniformly distributed along the center of sand cleaning hole.
Preferably, in above-mentioned technical proposal, it is disconnected cut groove be shaped as it is U-shaped or square.
Compared with prior art, cast cleaning pore structure of the invention advantageously reduces the cleaning that core cavity iron is cut
Difficulty and disposal costs and the cleannes for improving core cavity, ensure the beneficial effect of the product quality of casting.
Brief description of the drawings
Fig. 1 is the sectional view according to the cast cleaning pore structure of the present invention.
Fig. 2 is the A according to the cast cleaning pore structure of the present invention to partial view.
Main Reference Numerals explanation：
1- sand cleaning holes, 2- spot faces, 3- casting, 4- is disconnected to cut groove, 5- holes tail plane.
Embodiment
Below in conjunction with the accompanying drawings, the embodiment of the present invention is described in detail, it is to be understood that the guarantor of the present invention
Shield scope is not limited by embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members
Part or other parts.
As shown in Figure 1 to Figure 2, according to a kind of cast cleaning pore structure of the specific embodiment of the invention in sand cleaning hole 1
Afterbody increase, which is resolved, cuts the structure of groove 4, and disconnected groove 4 of cutting is arranged in the hole tail plane 5 of the inner side of casting 3 and connected with sand cleaning hole 1.
In some embodiments, the disconnected quantity for cutting groove 4 is at least three, is uniformly distributed along the center of sand cleaning hole 1.In sky
Between allow in the case of, it is disconnected cut groove 4 quantity it is as more as possible, it is disconnected cut the quantity of groove 4 more multi-processing when iron cut and just become more
Thin short, the cleaning that advantageously can be cut in core cavity iron.
In some embodiments, the shape for cutting groove 4 of breaking is as " u "-shaped or square.
In some embodiments, the disconnected depth for cutting groove 4 is 1.5mm~5mm, and width is 3mm~10mm.According to specifically setting
Meter situation, when sand cleaning hole 1d diameter is bigger, the disconnected depth and width for cutting groove 4 just should be bigger, is more advantageous to prevent iron from cutting group
Formation, the cleaning advantageously cut in core cavity iron.
In summary, cast cleaning pore structure of the invention advantageously reduce cleaning difficulty that core cavity iron cuts and
Disposal costs and the cleannes for improving core cavity, ensure the product quality of casting a little.
The description of the foregoing specific illustrative embodiment to the present invention is to illustrate and the purpose of illustration.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can be much changed
And change.The purpose of selecting and describing the exemplary embodiment is that explain that the certain principles of the present invention and its reality should
With so that those skilled in the art can realize and utilize the present invention a variety of exemplaries and
Various chooses and changes.The scope of the present invention is intended to be limited by claims and its equivalents.
