CN211965889U - Shakeout grille with water cooling function - Google Patents

Abstract

The utility model discloses a take water-cooled shakeout grid sets up the sand hopper in the bottom of shakeout grid, has both ends all to wear out the outer water-cooled tube of sand hopper in the sand hopper, one end of water-cooled tube is the water inlet, and another is the delivery port. The utility model discloses a take water-cooled shakeout grid can be through the water-cooled tube in the sand hopper when the molding sand falls into the sand hopper through the grid, and the cold water in the water-cooled tube carries out the heat exchange with the molding sand to tentatively cool down the molding sand, make the molding sand can enter into in the follow-up unit fast and handle for production efficiency. The shakeout grating is a pore plate with the diameter of 16cm, so that molding sand can fall conveniently, and castings and sundries are left on the grating.

Description

Shakeout grille with water cooling function

Technical Field

The utility model relates to a V method casting equipment field, specific saying so relates to a take water-cooled shakeout grid in this field.

Background

The shakeout grating is an important single-machine device in V-method casting, when castings after pouring and cooling need to be unpacked, a sand box and the castings inside the sand box are placed on the shakeout grating together, after the sand box is vacuumized, molding sand in the sand box passes through grating holes in the shakeout grating and falls into a sand hopper below the grating, then the molding sand is recycled through a subsequent series of processing, and the castings are lifted and transported to a polishing area by utilizing a lifting tool on the grating. And the molding sand is very high in temperature after coming out of the sand box, and the molding sand needs to be cooled by some cooling measures.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a take water-cooled shakeout grid is provided.

In order to solve the technical problem, the utility model discloses a following technical scheme:

the utility model provides a take water-cooled shakeout grid which improves and lies in: the bottom of the shakeout grating is provided with a sand hopper, a water-cooling pipe with two ends penetrating out of the sand hopper is arranged in the sand hopper, one end of the water-cooling pipe is provided with a water inlet, and the other end of the water-cooling pipe is provided with a water outlet.

Further, the shakeout grating is a hole plate with the diameter of 16 cm.

Furthermore, the pore plate is a steel plate.

The utility model has the advantages that:

the utility model discloses a take water-cooled shakeout grid can be through the water-cooled tube in the sand hopper when the molding sand falls into the sand hopper through the grid, and the cold water in the water-cooled tube carries out the heat exchange with the molding sand to tentatively cool down the molding sand, make the molding sand can enter into in the follow-up unit fast and handle for production efficiency. The shakeout grating is a pore plate with the diameter of 16cm, so that molding sand can fall conveniently, and castings and sundries are left on the grating.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Embodiment 1, as shown in fig. 1-2, this embodiment discloses a shakeout grille with water cooling, a sand hopper 2 is arranged at the bottom of the shakeout grille 1, a water-cooling pipe 3 with two ends penetrating out of the sand hopper is arranged in the sand hopper, one end of the water-cooling pipe is a water inlet 4, and the other end of the water-cooling pipe is a water outlet 5. In this example, the shakeout grid is a perforated plate with a diameter of 16 cm. The pore plate is a steel plate.

The sand box and the casting are placed on the shakeout grille with water cooling disclosed in the embodiment, after the vacuum is closed, the high-temperature molding sand passes through the holes in the grille and falls into the sand hopper, and the casting, the sand box and slightly larger sundries are lifted to a proper position above the grille through the lifting tool. The heat exchange is carried out through the contact with the water-cooling pipe when the high-temperature molding sand falls, so that the cooling of the high-temperature molding sand is accelerated. Meanwhile, water in the water-cooling pipe is continuously circulated and is always kept as cold water.

Claims (3)
