Abstract

The utility model discloses a be formed in overflow launder on cope molding sand surface comprises nowel and cope match, its characterized in that: the center of the upper surface of the upper box is provided with a pouring cup, and the periphery of the pouring cup is provided with a circle of overflow chutes. The utility model discloses, compared with the prior art, use automatic runner machine that mills, mill out the pouring basin and week through milling cutter and seted up the round overflow launder in week, caught by the overflow launder when the molten iron emerges from the pouring basin, avoid the molten iron trickling to cause the damage to casting machine track and belt, thereby avoided gluing the quality problems who causes the mold assembling unevenness to produce on the sand box simultaneously, the number of times that the operative employee cleared up has significantly reduced, and the molten iron after the collection is recoverable recycles, through the annular iron plate that the overflow launder formed after with the molten iron cooling, it is more convenient to collect.

Description

Overflow groove formed on upper box molding sand surface

Technical Field

The utility model relates to a casting technical field especially relates to an overflow launder that is formed at last case molding sand surface.

Background

The existing pouring system, manual or automatic pouring system, cannot accurately control the adding amount of molten iron, causes the outflow of the molten iron, causes the problems of damage of a casting machine track, increase of magnetic separation burden in entering molding sand, unevenness of a mould assembling box stuck on a sand box and the like, needs to be manually and frequently cleaned, and can also cause the tearing of a belt of an old sand returning system. Meanwhile, the overflowed molten iron is difficult to recycle, so that the cost is wasted. There is an urgent need for a method to solve these problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing an overflow groove formed on the surface of upper box molding sand.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a be formed in overflow launder on cope flask molding sand surface, includes the nowel and sets up the sand mould cope flask in the nowel top, its characterized in that: the center of the upper surface of the upper box is provided with a pouring cup, and the periphery of the pouring cup is provided with a circle of overflow chutes.

As a further description of the above technical solution:

the overflow groove is formed by connecting a plurality of round holes to form a circle, and the round holes can be in other shapes.

The utility model discloses following beneficial effect has:

compared with the prior art, this prevent sand mould casting case structure of molten iron overflow, through the round overflow launder that sets up in the pouring basin outside, catch by the overflow launder when the molten iron emerges from the pouring basin, avoid the molten iron to trickle and cause the damage to casting machine track and belt, thereby avoided gluing the quality problems who causes the mold assembling unevenness to produce on the sand box simultaneously, the number of times that the operative employee cleared up has significantly reduced, and the molten iron after the collection is recoverable recycles, the cyclic annular iron plate that forms after cooling the molten iron through the overflow launder, it is more convenient to collect.

In summary, in a static pressure molding line of a modern automatic casting factory, an upper box and a lower box are respectively subjected to sand adding and compaction to form respective cavities, the upper box is conveyed to an upper box line, and a sprue cup is milled by a milling cutter by using an automatic sprue milling machine. And (4) lowering the required sand core into the cavity of the lower box. And then the upper box and the lower box are re-assembled and sent to a pouring line for pouring. And molten iron is poured into the pouring cup during pouring. The position of the pouring cup is adjustable in three directions of XYZ, the XY determines the position of the pouring cup, and the Z axis determines the depth of the pouring cup. The sprue milling machine can automatically translate in two XY mutually vertical directions, after reaching a target position, the sprue milling machine rises from bottom to top (moves in the Z-axis direction), meanwhile, the milling cutter rotates at a high speed, and a sprue cup is milled on the back of an upper box sand mold. The milling cutter rotation is controlled by four servo motors in all, and the required functions are achieved.

Because manual control is not accurate enough during pouring, molten iron overflows the pouring cup during pouring, and a large number of subsequent problems are caused. The utility model discloses an original automatic runner machine that mills has been used, has bored probably 10 around the pouring basin more, and these round holes link to each other and have constituted the round overflow launder, and the molten iron that spills over gets into the overflow launder, has solved the follow-up problem that the molten iron spilled over in a large number and caused in the past. The positions of the round holes can move along with the positions of different pouring cups, the depth of the round holes can be adjusted, and the functions are realized by programming

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 2, the present invention provides an overflow groove formed on the surface of upper box molding sand: including sand mould nowel 1 and set up case 2 on the sand mould of 1 top of sand mould nowel, its characterized in that: a pouring cup 3 is arranged at the center of the upper surface of a sand mold upper box 2, a plurality of groups of overflow grooves 4 are arranged on the periphery of the pouring cup 3, two adjacent groups of the overflow grooves 4 are tangent and then communicated, overflowing molten iron enters the overflow grooves 4, and the subsequent problem caused by the fact that a large amount of previous molten iron overflows is solved.

The shape of the overflow groove 4 comprises but is not limited to one of a circle, a square and a polygon, a plurality of groups of overflow grooves 4 and mounting holes of the sprue cup 3 are obtained by processing through a sprue milling machine, the overflow groove 4 is processed by changing a processing program through the original sprue milling machine, the automatic processing mode is simple, and the popularization is easy

The working principle is as follows: when the pouring cup 3 is processed, the processing program of the overflow groove 4 is increased by modifying the processing program, molten iron overflowing from the pouring cup 3 enters the overflow groove 4 during casting, and after the molten iron in the overflow groove 4 is cooled, an iron block is formed, so that the collection and the recycling are convenient, and a plurality of problems caused by the overflow of the molten iron are solved.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
