Abstract

The utility model discloses a sand box with a window, and belongs to the casting technique. Compared with the sandbox with the window, the high ratio of casting mold sand to iron manufactured by an existing sand box causes that the cost of the casting mold is high, the lifting is difficult and potential safety hazards exist. According to the sand box with the window, an outer outline is formed by being enclosed by a box wall. An upper plane is arranged on the top of the outer outline. A mold cavity is arranged between the upper plane and the outer outline. The upper plane is provided with the window, wherein the window communicated with the mold cavity is smaller than the outer outline. Due to the fact that the sand box with the window is adopted, a small sand box matched with the size of the window can be adopted above the window. Not only can the ratio of the sand and the iron be greatly reduced and cost be saved, but also the weight of the whole casting mold can be reduced. Using lifting equipment is safe, and at the same time the potential safety hazard is greatly reduced.

Description

Sandbox with window

Technical field

The utility model belongs to foundry engieering, especially a kind of sand box used for casting for reducing the placer iron ratio.

Background technology

In general Foundry Works, the foundry goods that is cone or Pyramid during for cast, often adopt the same sandbox of length and width size, like this closer to microcephaly's placer iron of foundry goods than higher (placer iron is than the ratio that is the used molding sand weight of casting mold of making and it weight of molten iron that can pour into), in case placer iron is than high, then cost improves accordingly; In addition, the weight of whole casting mold also can increase the weight of thereupon, for the casting mold of length greater than the formation of the sandbox more than 2 meters, often impact lifting after weight increases the weight of in the limited situation of the lifting weight of crane gear, even can't be lifted by crane, sometimes reluctantly lifting, this has consisted of very large potential safety hazard.

The utility model content

The technical assignment of the technical problems to be solved in the utility model and proposition is the defective that overcomes that the placer iron of the casting mold that existing sandbox makes is higher than the high casting cost that brings, lifting is difficult, has potential safety hazard, a kind of sandbox with window is provided, in order to reduce the placer iron ratio, the shape of this window and size can be mated with the existing sandbox of factory.

For achieving the above object, sandbox with window of the present utility model, it surrounds outline by tank wall, and upper plane is arranged at the top of outline, in upper plane and outline, die cavity is arranged, it is characterized in that: establish less than window outline and that be communicated with described die cavity on the described upper plane.

As the optimization technique means, described window is surrounded by tabular case band.

As the optimization technique means, described window is surrounded by tabular case band and described tank wall.

As the optimization technique means, described case band be located at described upper plane on reinforcement or/and tank wall be fixedly connected with.

As the optimization technique means, described window is surrounded by at least 3 planes.

As the optimization technique means, described window is surrounded by curved surface.

As the optimization technique means, the outside of described tank wall is fixed with at least a in reinforcement, handle, the case ear.

As the optimization technique means, be furnished with the case ear on the described upper plane.

The beneficial effects of the utility model are: the sandbox that window is arranged by employing, can more than window, adopt like this sand buggy with the window size coupling, not only can reduce greatly the placer iron ratio, save cost, and can reduce the weight of whole casting mold, this use to crane gear is safer, has also reduced greatly potential safety hazard simultaneously.

Description of drawings

Fig. 1 is a kind of structural representation of the present utility model;

Fig. 2 is that A-A among Fig. 1 is to cutaway view;

Number in the figure explanation: 1-case ear, 2-handle, 3-tank wall, the upper plane of 4-, 5-case band, 6-inner plane, 7-reinforcement, 8-window, 9-outline.

The specific embodiment

Below in conjunction with Figure of description the utility model is described further.

Sandbox with window of the present utility model, as shown in Figure 1, 2, it surrounds outline 9 by tank wall 3, and upper plane 4 is arranged at the top of outline 9, in upper plane 4 and outline 9 die cavity is arranged, and establishes less than window 8 outline and that be communicated with die cavity on the upper plane 4.The shape of window 8 and size can be mated with the existing sandbox of factory.

As further improving and replenishing technique scheme, the utility model also comprises following additional technical characterictic, although Fig. 1-2 has comprised following all additional technical features, it is preferred embodiment of the present utility model, but the utility model is not limited to this situation, according to specifically acting on they is selected on the described technical scheme of epimere when implementing the utility model.

At first, according to the shape of foundry goods, window 8 is surrounded by tabular case band 5, is perhaps surrounded with tank wall 3 by tabular case band 5.Further, for fastness and the intensity of guard box band 5, case band 5 be located at upper plane 4 on reinforcement 7 or/and tank wall 3 be fixedly connected with.

Secondly, window 8 is surrounded by at least 3 planes, is perhaps surrounded by curved surface.

The 3rd, the outside of tank wall 3 is fixed with reinforcement (in order to strengthen tank wall intensity and to avoid distortion), handle 2(so that lifting), case ear 1(is so that the fastening usefulness of screw rod) at least a.

The 4th, be furnished with case ear 1 on the upper plane 4, be used for the sand buggy of immovable fitting on window.

By above scheme, can reach and reduce the placer iron ratio, save cost and reduce the weight of whole casting mold, the purpose of reduction potential safety hazard.

In addition, be illustrated as the example of 4 limit shape windows, except this example, it can also be the window of 3 limit shapes and unnecessary 3 limit shapes, and key is the size and dimension coupling that can have with factory sand buggy now.
