Description

Technical Field

[0001] The utility model belongs to the technical field of sand-shaking equipment, in particular to a sand-shaking machine. Background Art

[0002] Traditional castings are all made with sand molds. After the casting process is completed, the sand mold inside the casting needs to be cleaned out. The traditional method is to knock it with a wooden hammer. This method is inefficient, time-consuming and labor-intensive. Sand vibrating machines came into being. Sand vibrating machines on the market usually use an air hammer above the casting to knock the casting to shake out the sand in the casting. The shaken sand is discharged from the bottom of the casting. In actual use, the upper part of the casting is subjected to a larger knocking force, which is smaller when transmitted to the lower part, making it difficult to clean the sand at the bottom of the casting.

Four support columns 2 are provided, which are respectively located at the four corners of the fixing frame 3 and the top plate 1. The top and bottom of the support columns 2 are detachably connected to the top plate 1 and the fixing frame 3 by bolts, which is convenient for replacing and repairing the parts therein; the bottom of the fixing frame 3 is provided with a plurality of legs 11 to increase the stability of the entire device.

[0025] A sand-shaking device is provided between the top plate 1 and the fixing frame 3, which is used to provide vibration to shake out the sand in the casting; the sand-shaking device includes a lifting mechanism 4 and a plurality of air hammers 5 connected to the lifting mechanism 4, and the lifting mechanism 4 is connected to the top plate 1 to drive the air hammers 5 to move up and down. Specifically, the lifting mechanism 4 includes a cylinder 1, which is installed on the upper part of the top plate 1 through a cylinder seat, and its output shaft extends downward through the top plate 1 and is connected to the plurality of air hammers 5. When the cylinder 1 is working, it drives the air hammers 5 to move downward and contact the casting, and then the air hammers 5 work to knock the casting to clean the sand in the casting. In order to facilitate the connection of the plurality of air hammers 5, the upper parts of the plurality of air hammers 5 are connected to the mounting plate 9 by bolts, and the mounting plate 9 is connected to the lifting mechanism 4, that is, the mounting plate 9 is connected to the output shaft of the cylinder 1. At the same time, in order to prevent the mounting plate 9 from deflecting during the up and down movement, the mounting plate 9 is provided with a plurality of through holes passing through the support column 2, and the support column 2 and the through holes are used in conjunction with each other to play a guiding role to ensure the linearity of the movement of the mounting plate 9.

[0026] A support seat 6 corresponding to the air hammer 5 is provided inside the fixing frame 3. The support seat 6 is used to place the casting. In order to prevent the casting on the support seat 6 from moving during the operation of the air hammer 5, a clamping mechanism 8 is provided on the support seat 6. The clamping mechanism 8 is used to clamp the casting on the support seat 6 and position the casting. In this embodiment, the clamping mechanism 8 includes a cylinder 8-1 and a clamping plate 8-2. The cylinder 8-1 is installed on the outer side wall of the support seat 6 through the cylinder seat, and its output shaft passes through the side wall of the support seat 6 and is connected to the clamping plate 8-2. After the casting is placed on the support seat 6, the cylinder 8-1 is started to drive the clamping plate 8-2 to move in the direction close to the casting to clamp and fix the casting. In order to increase the friction between the clamping plate 8-2 and the casting and avoid relative movement between the clamping plate 8-2 and the casting, an anti-skid pad is provided on the side of the clamping plate 8-2 away from the cylinder 8-1. The material of the anti-skid pad can be rubber.

When the motor 7-1 is started, the output shaft drives the support seat 6, the clamping mechanism 8 and the casting to rotate, and the casting stops when it rotates to a suitable position, and then it is struck by an air hammer 5 so that the sand grains on the casting can fall off better.

[0028] When the device is used, the casting is placed on the support seat 6, and the casting is fixed on the support seat 6 by driving the clamping plate 8-2 through the second cylinder 8-1; the cylinder starts to drive the air hammer 5 close to the casting, and the air hammer 5 works to knock the upper part of the casting to shake off the sand; the cylinder starts to drive the air hammer 5 away from the casting, and the motor 7-1 works to drive the support seat 6 and the casting to rotate, and the rear cylinder starts to drive the air hammer 5 close to the casting, and the air hammer 5 works to knock the corresponding position of the casting and the air hammer 5 to clean the sand; the rotation of the support seat 6 and the operation of the air hammer 5 are repeated, and different parts of the casting are knocked many times, so that the sand on the casting is cleaned more cleanly. In order to facilitate the collection of sand particles and the air hammer 5 can still knock the casting after the casting rotates 180°, in this embodiment, the support seat 6 is in a square frame shape, and a plurality of connecting strips 6-1 are provided at the lower part thereof, and the sand particles fall through the gaps between the connecting strips 6-1, and the air hammer 5 can also knock the casting through the gaps between the connecting strips 6-1.
