Abstract
The utility model discloses a low-pressure casting die for left and right connecting supports of an automobile, which comprises a die body and is characterized in that: a flow dividing cavity is arranged in the middle of the interior of the die body and is communicated with a liquid inlet on the outer wall of the die body; support molding cavities arranged at intervals are arranged around the shunting cavity in the die body, and the convex handle parts of the support molding cavities are communicated with the shunting cavities through independent runners respectively. The utility model can well perform feeding on all parts of the left and right connecting brackets by designing the flow dividing cavity and the plurality of bracket forming cavities arranged around the flow dividing cavity and feeding materials from the convex handle parts of the left and right connecting brackets, thereby avoiding shrinkage porosity, improving casting quality and further improving the yield of products.
Description
Technical Field
The utility model relates to the field of casting of left and right connecting supports of automobiles, in particular to a low-pressure casting die for the left and right connecting supports of the automobiles.
Background
Along with the development of new energy automobiles, the demand for lightweight aluminum alloy brackets is also increased. Improving the casting quality of the aluminum alloy bracket and reducing the cost become key problems of manufacturers. The low-pressure casting has the advantages of better mold filling capacity, lower air hole occurrence rate, better compactness, better mechanical property and the like. However, the problem of low yield exists in the prior art that the left and right connecting brackets of the automobile are cast by low pressure.
Disclosure of Invention
In order to overcome the defects in the prior art, the utility model aims to provide a low-pressure casting die for left and right connecting supports of an automobile, so that the yield is improved.
In order to achieve the purpose, the utility model adopts the following technical scheme:
a low-pressure casting die for left and right connecting supports of an automobile comprises a die body, wherein a flow dividing cavity is arranged in the middle of the interior of the die body and is communicated with a liquid inlet in the outer wall of the die body; the die is characterized in that support forming cavities are arranged around the shunting cavity inside the die body at intervals, and the convex handle parts of the support forming cavities are communicated with the shunting cavity through independent runners.
Further, the cross section of the shunting cavity is circular.
Furthermore, the number of the support forming cavities is 6, and the 6 support forming cavities are arranged around the support forming cavities at equal intervals along the circumferential direction.
By adopting the technical scheme, the feeding device has the advantages that the flow distribution cavity and the support forming cavities arranged around the flow distribution cavity are designed, and the feeding is carried out from the convex handle parts of the left connecting support and the right connecting support, so that the feeding can be well carried out on all parts of the left connecting support and the right connecting support, the shrinkage porosity is avoided, the casting quality is improved, and the product yield is improved.
Drawings
The utility model is described in further detail below with reference to the accompanying drawings and the detailed description;
FIG. 1 is a schematic view of the interior of the inventive mold;
fig. 2 is a schematic view of a cast product.
Detailed Description
Referring to fig. 1 and 2, the low-pressure casting die for the left and right connecting supports of the automobile comprises a die body 1, wherein a shunting cavity 2 is arranged in the middle of the inside of the die body 1, and the shunting cavity 2 is communicated with a liquid inlet on the outer wall of the die body 1; support molding cavities 3 arranged at intervals are arranged around the shunting cavity 2 inside the die body 1, and convex handle parts of the support molding cavities 3 are communicated with the shunting cavity 2 through respective independent runners 4.
Preferably, the cross-section of the distribution chamber 2 is circular. The design can evenly distribute the aluminum liquid to each support forming cavity 3.
In this embodiment, the number of the stent forming cavities 3 is 6, and the 6 stent forming cavities 3 are arranged around the stent forming cavity 3 at equal intervals along the circumferential direction.
According to the utility model, the flow distribution cavity 2 and the plurality of support forming cavities 3 arranged around the flow distribution cavity 2 are designed, and feeding is carried out from the convex handle parts of the left and right connecting supports (so as to form a solid convex handle, and the convex handles of the original left and right connecting support castings are of a hollow structure and are easy to shrink, so that each part of the left and right connecting supports can be well fed, the shrinkage porosity is avoided, the casting quality is improved, and the product yield is improved.
While the utility model has been described in connection with the above embodiments, it is to be understood that the utility model is not limited to the disclosed embodiments, which are illustrative and not restrictive, and that those skilled in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
