Abstract

The invention relates to an iron box water cooling device for an iron mold sand coating process. The iron box water cooling device comprises a bracket, a movable guide wheel, iron boxes, water inlet pipes, water spraying pipes, a water returning pipe, a support frame, a water stop pool, sensors and a reservoir, wherein the iron boxes arranged on the movable guide wheel; the water spraying pipes are arranged at the upper and lower sides of the iron boxes; the two ends of the water spraying pipes are respectively connected with the water inlet pipes; the sensors are arranged on the water spraying pipes; water inlets of the water inlet pipes are connected with the reservoir below the water spraying pipes; and the water stop pool is additionally arranged between the water spraying pipe at the lower side of the iron box and the reservoir, and is connected with the reservoir through the water returning pipe. The iron box water cooling device for the iron mold sand coating process can effectively control the water spraying time and the water spraying quantity through the sensors so as to evenly cool each of the iron boxes; the surfaces of sand coating layers in cavities are orange after the cooling, and are high in strength; and sprayed water is recycled through the water stop pool and the reservoir, so that the existing ponding working environment is improved, and the most water resource is saved.

Description

A kind of iron case water-cooling apparatus for device for sand coated iron mould technique

Technical field

The invention belongs to casting field, be specifically related to a kind of iron case water-cooling apparatus for device for sand coated iron mould technique.

Background technology

At present, when every case foundry goods of producing on device for sand coated iron mould production line exceedes 100KG, iron case temperature after casting complete often exceedes 300 DEG C, and what usually occur mold cavity surface covers layer of sand because excess Temperature burns, and causes sand strength decreased, produces drop waste product part.

For head it off, by adopting water pistol toward iron case surface sprinkling, but still there is following problem: die cavity sand intensity difference, percent defective is high; Water is sprayed onto on iron case, forms ponding, causes poor working environment; The consumption of water is large, causes the waste of water resource.

Summary of the invention

The object of the invention is to, for above-mentioned the deficiencies in the prior art, a kind of iron case water-cooling apparatus for device for sand coated iron mould technique is provided, this device not only can effectively be controlled water spraying time and the water spray water yield, thereby reach the uniform decrease in temperature to iron case surface, avoid the generation of drop waste product part, but also can utilize cistern and dash pond to making water recycling, greatly improve working environment, saved water resource.

In order to reach foregoing invention object, the technical scheme that the present invention takes is as follows:

A kind of iron case water-cooling apparatus for device for sand coated iron mould technique, comprise bearing 1, movable guide wheel 2, iron case 3, water inlet pipe 4, sparge pipe 5, return pipe 6, bracing frame 7, shelves pond 8, sensor 9 and cistern 10, on described bearing 1, be connected with movable guide wheel 2 by bearing, on described movable guide wheel 2, be provided with iron case 3, described iron case 3 upper, near lower both sides, be respectively arranged with sparge pipe 5, the two ends of described sparge pipe 5 are connected with water inlet pipe 4 respectively and are provided with sensor 9 on its sparge pipes 5, the water inlet of described water inlet pipe 4 is connected with the cistern 10 that is positioned at described sparge pipe 5 belows, meanwhile, the middle and lower part of described water inlet pipe 4 is fixedly connected with described bearing 1, middle and upper part is fixedly connected with described bearing 1 by bracing frame 7, between the sparge pipe 5 of described iron case 3 downsides and described cistern 10, be also provided with dash pond 8, between described dash pond 8 and described cistern 10, be connected by return pipe 6.

Further, the sparge pipe 5 of described upper and lower both sides is respectively four.

Beneficial effect of the present invention: the present invention can effectively control water spraying time and the water spray water yield by sensor, thereby reaches each iron case uniform decrease in temperature, and the layer of sand surface of covering after cooling in die cavity is orange colour, and intensity is high; The present invention, by adopting dash pond, cistern that the water of ejection is recycled and reused, has improved existing ponding working environment, has also saved a large amount of water resources simultaneously.

Detailed description of the invention

Below in conjunction with embodiment and accompanying drawing, embodiments of the present invention are described in further detail:

As Fig. 1, shown in 2, a kind of iron case water-cooling apparatus for device for sand coated iron mould technique, comprise bearing 1, movable guide wheel 2, iron case 3, water inlet pipe 4, sparge pipe 5, return pipe 6, bracing frame 7, shelves pond 8, sensor 9 and cistern 10, on described bearing 1, be connected with movable guide wheel 2 by bearing, on described movable guide wheel 2, be provided with iron case 3, described iron case 3 upper, 80mm place, lower both sides is respectively arranged with four sparge pipes 5, the two ends of described sparge pipe 5 are connected with water inlet pipe 4 respectively and are provided with sensor 9 on its sparge pipes 5, the water inlet of described water inlet pipe 4 is connected with the cistern 10 that is positioned at described sparge pipe 5 belows, meanwhile, the middle and lower part of described water inlet pipe 4 is fixedly connected with described bearing 1, middle and upper part is fixedly connected with described bearing 1 by bracing frame 7, between the sparge pipe 5 of described iron case 3 downsides and described cistern 10, be also provided with dash pond 8, between described dash pond 8 and described cistern 10, be connected by return pipe 6.

In the time that iron case 3 is sent to a certain position by movable guiding rail 2, sensor 9 on sparge pipe 5 detects after signal, start the compression pump (not shown in FIG.) in cistern 10, compression pump is pressed into water in water inlet pipe 4 and sprays uniform decrease in temperature is carried out in iron case surface through sparge pipe 5, in the time that iron case 3 is passed out to a certain position by moving guide rail 2, the sensor 9 on sparge pipe 5 can't detect after signal, stops the compression pump operation in cistern 10, every case water spraying time is 1min, specifically according to circumstances determines.
