Abstract

The utility model discloses a novel axel housing sandbox. A sandbox inner cavity with the coarse surface is formed in the axle housing sandbox; a plurality of vent holes and a plurality of tie bars are arranged on the surface of the sandbox inner cavity, and the tie bars are uniformly distributed and are connected with one another along curved surfaces; the axle housing sandbox is matched with a mold in shape; the thickness of the sandbox is uniform and is 5-35mm. The novel axle housing sandbox has the beneficial effects that the sandbox is compact in structure, firm, durable and small in deformation; the structure of the sandbox is matched with the shape of the mold and is low in sand consumption, so that sand is saved; because a sand layer is thin, a heat conduction effect is good, and after pouring, the surface temperature gradient of a casting is large, and the outer layer material of the casting has exquisite grains and good in mechanical property.

Description

A kind of novel axle housing sandbox

Technical field

The utility model relates to a kind of novel axle housing sandbox.

Background technology

Traditional axle housing sandbox sand using amount is large, and sand layer thickness is large, and the foundry goods heat radiation is slow, and mechanical castings is poor, and during batch production, seriously, use cost is higher in the molding sand waste.In order to raise the efficiency, the production of axle housing adopts device for sand coated iron mould technique, and now, traditional axle housing sandbox can not use.Therefore in order reducing costs, to meet the requirement of technique, to need a kind of novel sandbox badly.

The utility model content

In order to solve the problem of above-mentioned existence, the utility model specifically discloses a kind of novel axle housing sandbox, this sandbox compact conformation, sturdy and durable, be out of shape littlely, mold thickness is little, economizes on sand.

To achieve these goals, the concrete scheme that the utility model adopts is as follows:

A kind of novel axle housing sandbox, sandbox and mould are except the sealing of steam vent outer contacting face, the cavity wall thickness formed between sandbox and mould is even, for 5-35mm, axle housing sandbox inside is provided with shaggy sandbox inner chamber, some steam vents and some lacing wires are arranged on the sandbox inner cavity surface, and lacing wire is evenly distributed, and between each lacing wire, along curved surface, connects.

Described axle housing sandbox cavity shape matches with the shape of die shape.

The manufacturing process of novel axle housing sandbox: at first design sand tank model, then by figure, process foam, the 3rd use forging type casts out blank, and the 4th at Digit Control Machine Tool processing sandbox.Some steam vents are arranged on cavity face, and during moulding, steam vent guides molding sand to fill type by air-flow, it should be noted that sandbox inner chamber machined surface surface wants roughing, and coarse, large with molding sand frictional force like this, and sandbox and molding sand bonding force are larger.

The beneficial effects of the utility model are:

1, the sandbox compact conformation, sturdy and durable, be out of shape little;

2, sandbox structure and mould are with type, and mold thickness is little, economize on sand;

3, because sand layer thickness is thin, good heat conduction effect, after cast, the cast outer surface thermograde is large, the outer material crystal grain of foundry goods exquisiteness, mechanical property is good.

The accompanying drawing explanation

The structural representation of Fig. 1 the utility model embodiment;

The existing axle housing sandbox of Fig. 2 structure chart;

In figure, 1 lacing wire, 2 steam vents, 3 curved surfaces, 4 sandbox inner chambers.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment, the utility model is further described.

As shown in Figure 1, a kind of novel axle housing sandbox, axle housing sandbox middle part is provided with shaggy sandbox inner chamber 4, on 4 of sandbox inner chambers, some steam vents 2 and some lacing wires 1 are arranged, lacing wire 1 is evenly distributed, and between each lacing wire 1, along curved surface 3, connects, and the axle housing sandbox matches with the shape of mould, the sandbox even thickness is 5-35mm.As shown in Figure 2, axle housing sandbox sand using amount is large for existing axle housing sandbox, and sand layer thickness is large, and the foundry goods heat radiation is slow, and mechanical castings is poor, and the waste of batch production molding sand is serious, and use cost is higher.

Claims (3)

1. a novel axle housing sandbox, is characterized in that, axle housing sandbox inside is provided with shaggy sandbox inner chamber, and some steam vents and some lacing wires are arranged on the sandbox inner cavity surface, and lacing wire is evenly distributed, and between each lacing wire, along curved surface, connects.

2. a kind of novel axle housing sandbox as claimed in claim 1, is characterized in that, described axle housing sandbox matches with the shape of mould.

3. a kind of novel axle housing sandbox as claimed in claim 1, is characterized in that described sandbox even thickness is 5-35mm.
