Description

Sand saving sand box for open type castings

Technical Field

The utility model relates to a sand-saving sand box for an open casting, and belongs to the technical field of casting.

Background

When designing a 1/3 rotor casting sand box, the structure of the casting is in an open L shape, and according to the traditional design thought, the sand box is in a square shape, so that the sand-iron ratio of the product is extremely high. Too high sand-iron ratio also causes an increase in sand discharge time, so that the production period of the castings is greatly increased; meanwhile, the excessive sand consumption greatly increases the lifting and turning pressure in the workshop production process.

Disclosure of Invention

The utility model aims to solve the technical problem of providing the sand-saving sand box for the open casting in the prior art, which can reduce the sand-iron ratio of the casting and reduce the sand discharge time.

The utility model solves the problems by adopting the following technical scheme: the sand-saving sand box for the open-type casting comprises a profiling sand box and a mud core sand-saving unit, wherein the mud core sand-saving unit is arranged in the profiling sand box, and a profiling cavity of the open-type casting is formed between the inner wall of the profiling sand box and the outer wall of the mud core sand-saving unit; the top of the profiling sand box is provided with a pouring opening which is communicated with the profiling cavity through a pouring channel; the sand saving unit of the mud core comprises the mud core, and a sand saving frame of the mud core is arranged in the mud core, so that the mud core is hollow, and a plurality of supporting blocks are arranged at the bottom of the mud core.

The copying sand box comprises a bottom box and a cover box, wherein the cover box is arranged above the bottom box, a middle ring box group is arranged between the cover box and the bottom box, and a mud core sand saving unit is arranged on the cover box.

The profiling sand box is an octagonal structural member.

The middle ring box group comprises a plurality of middle ring boxes which are overlapped.

Compared with the prior art, the utility model has the advantages that: a sand-saving sand box for open type foundry goods, the profile modeling sand box combines together with mud core sand-saving unit, and the profile modeling sand box is traditional square sand box's improvement, according to the structure of foundry goods, laminates open type foundry goods more with the profile modeling sand box, mud core sand-saving unit just makes hollow with mud core, finally reaches the biggest sand-saving volume, has reduced the sand-iron ratio of foundry goods, has reduced the time of putting sand, has improved production efficiency.

Detailed Description

The utility model is described in further detail below with reference to the embodiments of the drawings.

As shown in fig. 1, 2 and 3, a sand-saving sand box for an open casting in this embodiment includes a profiling sand box and a sand-saving unit for a mud core, the sand-saving unit for a mud core is disposed in the profiling sand box, and a profiling cavity 10 for the open casting is formed between an inner wall of the profiling sand box and an outer wall of the sand-saving unit for a mud core. The top of the profiling sand box is provided with a pouring opening 6, and the pouring opening 6 is communicated with the profiling cavity through a pouring channel. Molten iron flows into the pouring channel through the pouring gate 6 and then enters the profiling cavity 10, so that an open casting is formed. The profiling sand box is an octagonal structural member and is matched with the open casting. The profiling sand box comprises a bottom box 4 and a cover box 1, wherein the cover box 1 is arranged above the bottom box 4, a middle ring box group is arranged between the cover box 1 and the bottom box 4, and the cover box 1 is covered with a mud core sand saving unit.

The mud core sand-saving unit comprises a mud core 9, a mud core sand-saving frame 5 is arranged in the mud core 9 in a penetrating manner, the mud core 9 is a hollow structural member, a plurality of supporting blocks 7 are arranged at the bottom of the mud core 9, the mud core is large and heavy and needs hard point support, the mud core cannot be supported by sand, and the supporting blocks 7 play a supporting role on the mud core. And a tightening sand 8 is filled between the top of the sand saving frame 5 of the mud core and the bottom of the cover box 1 for sealing.

The middle ring box group comprises a first middle ring box 2 and a second middle ring box 3, and the first middle ring box 2 is overlapped on the second middle ring box 3.

The sand-saving device is characterized in that the sand-saving unit is combined with the sand-saving unit of the sand core, the sand-saving unit of the sand core is hollow, the maximum sand-saving amount is finally achieved, the sand-iron ratio of the casting is reduced, the sand-discharging time is reduced, and the production efficiency is improved.
