Description
Technical field
The present invention relates to sand casting fields, and in particular to a kind of sand high-precision cast frock.
Background technology
In China and world wide, most of casting practicality sand mould casting method production, sand casting refers to certain
The casting method of casting mold and sand core is made up of different consolidation methods for type (core) sand of performance, it has, and flexibility is big, produces
The advantages that cycle is short, cheap.
Since the Modeling Material used in sand casting is cheap and easy to get, Casting mold manufacturing is easy, single-piece production to casting, in batch
Production and mass production adapt to, and are always the basic technology in Foundry Production for a long time.In general, making casting model powder
Sprue gate is connected with cast passage core during type, is not easy to safeguard.And mold will be cleared up after the completion of casting it is broken
Sand, metal fillings etc. directly clear up mold after taking out casting with compressed air, and the impurity such as remaining broken sand, metal fillings are very in cavity
It is easily blown into cast gate, when casting again, is back to molten metal in casting mold, scrap part casting, during cast
If cast passage shifts, the quality of casting can be also greatly affected.
The content of the invention
It is caused by the prior art above-mentioned more to solve it is an object of the invention to provide a kind of sand high-precision cast frock
Item defect.
A kind of sand high-precision cast frock, the cast washer coordinated including cope and with it are opened up on the cope
Have a sandbox sprue gate, the cast washer offers washer sprue gate for circular and centre position, the sandbox sprue gate with
Washer sprue gate is engaged and size is consistent with each other, and the opening at washer sprue gate is equipped with cast passage, and the cast passage is
Funnel-form opens up two fluted, the groove inner wall is provided symmetrically bullets on the cope of sandbox sprue gate periphery
Property protrusion, in the cast washer lower face of washer sprue gate periphery equipped with locating piece, the side wall of the locating piece offers and institute
State the matched card slot of elastic bumps.
Preferably, the elastic bumps are fixedly connected with the inner wall of groove.
Preferably, the number of the locating piece is equal to the number of groove, and is multiple.
Preferably, the bottom surface of the groove is arc surface, and the lower face of the locating piece is matched with groove floor
Circular arc protrusion.
Preferably, the bottom surface of the card slot is arc surface, and the face that the elastic bumps are contacted with card slot bottom surface is convex for circular arc
It rises.
The advantage of the invention is that：
1st, the groove that cope covers in the present invention can be accurately positioned with pouring into a mould the clamping apparatus that the locating piece of washer is formed,
Reliability is high；
2nd, it is easy to operate during installation of the invention cast washer, it is easy to use and at low cost；
3rd, the face that both locating piece and groove contact with each other is arc, possesses certain guide-localization effect, similarly
Elastic bumps are made of elastic material, are flexible coupling with card slot with being combined into, and also possess certain guide-localization effect, facilitate positioning
When inaccurate, adjustment position, which is realized, to be accurately positioned；
4th, the cooperation of locating piece and groove, elastic bumps and card slot so that position will not be occurred easily by pouring into a mould washer and cope
It moves or separates, ensure that in casting process, pouring position is stablized, and effectively protects sand mold.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is the enlarged diagram at A in Fig. 1 of the present invention.
Wherein, 1- pours into a mould washer, 11- cast passages, 12- locating pieces, 2- copes, 21- elastic bumps.
Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, with reference to
Specific embodiment, the present invention is further explained.
As shown in Figure 1 to Figure 2, a kind of sand high-precision cast frock, including cope 2 and the cast washer 2 coordinated with it,
Sandbox sprue gate is offered on the cope 2, the cast washer 1 offers washer cast for circular and centre position
Mouthful, the sandbox sprue gate is engaged with washer sprue gate and size is consistent with each other, and the opening at washer sprue gate is equipped with cast
Passage 11, the cast passage 11 is funnel-form, and fluted, the groove is opened up on the cope 2 of sandbox sprue gate periphery
Two elastic bumps 21 that inner wall is provided symmetrically are equipped with locating piece in 1 lower face of cast washer of washer sprue gate periphery
12, the side wall of the locating piece 12 offers and the 21 matched card slot of elastic bumps.
In the present embodiment, the elastic bumps 21 are fixedly connected with the inner wall of groove.
In the present embodiment, the number of the locating piece 12 is equal to the number of groove, and is multiple.
In the present embodiment, the bottom surface of the groove is arc surface, and the lower face of the locating piece 12 is and groove floor
Matched circular arc protrusion.
In the present embodiment, the bottom surface of the card slot be arc surface, the face that the elastic bumps 21 are contacted with card slot bottom surface
For circular arc protrusion.
The present invention operation principle be：During cast, washer sprue gate is alignd with sandbox sprue gate, cast passage 11 is slow
It fills in sandbox sprue gate, then the upper surface that the tiling of washer 1 hits sandbox 2 will be poured into a mould, pourer is carried out out of cast passage 11
Make, when cope 2 coordinates with cast washer 1, elastic bumps 21 are gradually subject to the extruding of locating piece 12 to generate deformation, and finally fill in
Enter into card slot, locating piece 12 can be tucked into groove at this time；Want when washer 1 is poured into a mould in movement, it is necessary to overcome elastic bumps 21
Elastic force so that elastic bumps 21 depart from out of card slot, could cause pour into a mould washer 1 and cope separation or generate displacement.
Based on above-mentioned, advantage of the invention is that：
1st, the clamping apparatus of locating piece 12 composition of the groove of cope set 2 with pouring into a mould washer 1 can be accurate in the present invention
Positioning, reliability are high；
2nd, it is easy to operate during installation of the invention cast washer 1, it is easy to use and at low cost；
3rd, the face that both locating piece 12 and groove contact with each other is arc, possesses certain guide-localization effect, equally
Elastic bumps 21 be made of elastic material, be flexible coupling with card slot with being combined into, also possess certain guide-localization effect, it is convenient
During position inaccurate, adjustment position, which is realized, to be accurately positioned；
4th, locating piece 12 and the cooperation of groove, elastic bumps 21 and card slot cause cast washer 1 will not be easily with cope 2
It is subjected to displacement or separates, ensure that in casting process, pouring position is stablized, and effectively protects sand mold.
As known by the technical knowledge, the present invention can pass through the embodiment party of other essence without departing from its spirit or essential feature
Case is realized.Therefore, embodiment disclosed above, all things considered are all merely illustrative, not the only.Institute
Have within the scope of the present invention or be included in the invention in the change being equal in the scope of the present invention.
