Abstract
The utility model discloses a sand mould for casting an automobile air pump shell. According to the sand mould, an upper sand mould and a lower sand mould are buckled and connected to form eight cavities (1) arranged at intervals, and an ingate (3) is communicated with all the cavities (1); the ingate is communicated with a straight gate (4) arranged on the upper end surface of the upper sand mould; and sand cores (2) of the air pump shells are respectively arranged in the eight cavities. With the adoption of the sand mould, the aim of casting eight automobile air pump shell blanks at the same time with one group of sand moulds is realized, the production efficiency is obviously improved, and the labor intensity of operating workers is lowered; and according to tests: compared with the prior art, the weight ratio of molten iron of each group needed for casting the straight gate and the ingate to the molten iron for casting the automobile air pump shell blanks is reduced about 35%, so that the production cost for casting is effectively reduced.
Description
(1) technical field: the utility model relates to the cast moulding tool; Be specifically related to a kind of sand mold of casting of automobile air pump housing.
(2) background technology: the sand mold of casting of automobile air pump housing in the prior art mainly is to be built-in with core at the Automobile air pump case die cavities that involutory four of the compositions that join of upper and lower sand mold are the spacing arrangement to constitute.It exists not enough: the one, and four Automobile air pump case of every group of sand casting blank production efficiency is on the low side, has increased operator's labour intensity; The 2nd, the weight of molten iron that every group of casting sprue and the required weight of molten iron of ingate take casting Automobile air pump case blank compares about 15%.After the Automobile air pump case casting processing, the foundry goods that remove sprue and ingate has increased the production cost of casting significantly again through smelting furnace processing fusing.
(3) summary of the invention: to the deficiency that above-mentioned prior art exists, the purpose of the utility model is to provide a kind of sand mold of casting of automobile air pump housing, is intended to enhance productivity, and reduces operator's the labour intensity and the production cost of casting.
For realizing above-mentioned purpose, the technical scheme of the utility model casting of automobile air pump housing sand mold is achieved in that the air pump housing core that comprises upper and lower sand mold and place its die cavity; It is to be communicated with ingate at the die cavities that involutory eight of the compositions that join of said upper and lower sand mold are the spacing arrangement; Said ingate all is communicated with the sprue that last sand mold upper surface is provided with; In described eight die cavities, be equipped with air pump housing core respectively.
The utility model is through taking said structure, realized that every group of sand mold can cast eight Automobile air pump case blanks simultaneously, improved production efficiency significantly and reduced operator's labour intensity; According to test: every group of casting sprue and the required weight of molten iron of ingate take the weight of molten iron ratio of casting Automobile air pump case blank, compare with prior art to have descended about 35%, have reduced the production cost of casting effectively.
(4) description of drawings:
Fig. 1 is the sectional front view of the utility model;
Fig. 2 removes the schematic top plan view that goes up sand mold among Fig. 1;
Fig. 3 is the three-dimensional view of the utility model casting of automobile air pump casing blank spare.
(5) specific embodiment: Fig. 1-shown in Figure 3.The sand mold of this casting of automobile air pump housing comprises upper and lower sand mold and places the air pump housing core of its die cavity; It is to be communicated with ingate 3 at the die cavities 1 that involutory eight of the compositions that join of said upper and lower sand mold are the spacing arrangement; Said ingate all is communicated with the sprue 4 that last sand mold upper surface is provided with; In described eight die cavities, be equipped with air pump housing core 2 (Fig. 1, shown in Figure 2) respectively.In the utility model when work,, the sprue 4 of casting molten iron through last sand mold upper surface be through ingate 3, gets into respectively in eight die cavities 1 that are equipped with air pump housing core 2, realized the casting to Automobile air pump case blank.Casting finishes, and eliminates the molding sand and removal air pump housing core of upper and lower sand mold, promptly accomplishes the casting processing (shown in Figure 3) to eight conjuncted Automobile air pump case blanks.
The above only is the preferred implementation of the utility model.Be noted that for those of ordinary skill in the art under the prerequisite that does not break away from the principle of the invention; Need not other technical characterictic that the process creative work just can be associated; Can also make the modification and/or the improvement of some kinds of basic identical modes, realize essentially identical function and produce essentially identical effect.These variations should be regarded as equivalent feature, all belong within the protection domain of the utility model patent.
Claims (1)
