Abstract
The utility model relates to a kind of mould casting backing plate sand mold, described backing plate has a base, described base have a pair protuberance, position on described base between its edge and described protuberance is offered porose respectively, described mould comprises the first mould, second mould, the second described mould comprises base plate, be arranged on the modular unit on described base plate, described modular unit comprises base template, be arranged on a pair protuberance template on described base template, position on described base template between its edge and described protuberance template offers recess, described protuberance template is copper insert.The utility model structure is simple, and easy to operation, shaping sand mold effectively can improve the accuracy of circular hole, overcomes the technical requirement to backing plate circular hole, effectively increases work efficiency.
Description
Technical field
the utility model relates to casting field, particularly relates to a kind of mould casting backing plate sand mold.
Background technology
backing plate as shown in Figure 3, backing plate 2 has a base 20, and base 20 has a pair protuberance 21, the position on base 20 between its edge and protuberance 21 offers porose 22 respectively.Backing plate 2, for the construction of high ferro, passes through sand casting forming at present.Cast the mould of this sand mold, adopt sand mold to cast at present.Mould when manufacturing sand mold all adopts aluminium block loose piece, because aluminium block fineness is low, cannot play withdrawing pattern effect, produces and amplifies gradient, because shaping backing plate circular hole precision techniques requires higher, does not reach the precise art requirement of this product after amplifying gradient.
at present, backing plate is diameter 48 to the requirement of circular hole
+0.5mm, can not steady production, causes cost to increase by increasing new operation.
Summary of the invention
the purpose of this utility model is to provide a kind of mould casting backing plate sand mold, and this mould is equivalent to the core of sand mold.
for achieving the above object, the technical solution adopted in the utility model is:
a kind of mould casting backing plate sand mold, described backing plate has a base, described base have a pair protuberance, position on described base between its edge and described protuberance is offered porose respectively, described mould comprises the first mould, second mould, the second described mould comprises base plate, be arranged on the modular unit on described base plate, described modular unit comprises base template, be arranged on a pair protuberance template on described base template, position on described base template between its edge and described protuberance template offers recess, described protuberance template is copper insert.
preferably, one side of something of described protuberance template is described copper insert.
further preferably, the relative one side of something of a pair described protuberance template is described copper insert, and all the other are aluminium block.
preferably, described base plate is provided with multiple described modular unit.
preferably, the surface roughness of described copper insert is not more than 0.8.
because technique scheme is used, the utility model compared with prior art has following advantages:
the utility model structure is simple, and easy to operation, shaping sand mold effectively can improve the accuracy of circular hole, overcomes the technical requirement to backing plate circular hole, effectively increases work efficiency; And mould main portions adopts edge copper billet, reduces pattern draft, pattern draft≤1 °, improve progress and the fineness of foundry goods, reduce costs.
Accompanying drawing explanation
accompanying drawing 1 is the schematic top plan view of the second mould in the utility model;
accompanying drawing 2 is the side view of the second mould in the utility model;
accompanying drawing 3 is the schematic diagram of backing plate.
wherein: 1, the second mould; 10, base plate; 11, modular unit; 110, base template; 111, protuberance template; 112, recess; 2, backing plate; 20, base; 21, protuberance; 22, hole; 3, copper insert.
Detailed description of the invention
below in conjunction with drawings and Examples, the utility model is further described:
a kind of mould casting backing plate sand mold as described in Fig. 1,2, mould comprises the first mould, the second mould 1, wherein: the base due to backing plate 2 is dull and stereotyped, therefore also there is not requirement in shape to the first calligraphy or painting model body.Second mould 1 comprises base plate 10, the modular unit 11 be arranged on base plate 10, and modular unit 11 can arrange multiple, and each modular unit 11 can a shaping backing plate sand mold.Specifically: modular unit 11 comprises base template 110, a pair protuberance template 111 be arranged on base template 110, position on base template 110 between its edge and protuberance template 111 offers recess 112, during use, by pressing sand on modular unit 11, shaping backing plate sand mold.Due to backing plate having hole, there is required precision to during the sand mold demoulding to its forming hole recess 112, therefore in the present embodiment protuberance template 111 is set to copper insert, in view of the fineness on copper surface is higher, its surface roughness is not less than 0.8, and there is the feature of self-lubricity, be conducive to reducing pattern draft, conveniently stripped.In addition, in view of the consideration on cost, one side of something of protuberance template 11 is copper insert 3, and the one side of something being specially a pair protuberance template 11 relative is copper insert 3, and all the other and other templates can select aluminium block.
mould main portions adopts edge copper billet 3, reduces pattern draft, original mould adopting aluminium alloy, and pattern draft≤3 ° adopt copper edge, 3, pattern draft≤1 ° now; The surface roughness of copper insert reaches 0.8S, improves progress and the fineness of foundry goods, reduces costs.
by the sand mold of the present embodiment die casting, shaping backing plate circular hole can reach diameter 48
+the technical requirement of 0.5mm, effectively reduces costs control, increases work efficiency.
above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
