[0002] Sand dropping machine is a casting equipment that uses vibration and impact to separate the molding sand and casting in the mold. The vibration sources of the sand dropping machine are divided into three categories: mechanical, electromagnetic and pneumatic. The mechanical inertia sand dropping machine is widely used. Sand casting is a casting method for producing castings in molding sand. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting. Since the molding materials used in sand casting are cheap and easy to obtain, the mold is simple to manufacture, and it can adapt to the single-piece production, batch production and mass production of castings. The sand dropping of castings is one of the important processes in the sand casting production process. Sand dropping is to break the mold after the mold is poured and cooled to a certain temperature, so that the mold is separated from the sand box, and the casting is separated from the molding sand.
[0003] Most of the existing sand-falling machines are equipped with a vibration motor outside the machine body, and the vibration motor cooperates with a spring to shake the molding sand off. Since the volume or area of the casting is smaller than that of the grid, the vibration amplitude of the casting may be smaller, resulting in incomplete sand falling and low efficiency.

A movable component 3 is movably installed on the inner side of the sliding hole 22, the sand-falling box 4 is movably installed on the inner side of the movable component 3, the sand-falling net 5 is fixedly installed on the inside of the sand-falling box 4, and a dust collection component 6 is movably installed on the top of the slide groove 23.
[0024] By providing a movable component 3, and by installing a sand-falling box 4 on the inner side of the movable component 3, the sand-falling box 4 and the movable component 3 can move, and the movable component 3 is located outside the mounting frame 2 to drive the movable component 3 to move horizontally, thereby driving the sand-falling box 4 to increase its range of motion, and a vibration motor is provided outside the sand-falling box 4 to vibrate and shake the workpiece on the sand-falling net 5 in the sand-falling box 4, so that the vibration sand-falling effect is better and the efficiency is higher. At the same time, by providing a dust suction component 6 above the mounting frame 2, the dust suction component 6 is located above the sand-falling box 4, and the dust generated during the sand-falling process is sucked in, filtered and discharged, and the dust is collected to prevent the dust from flying and affecting the health of the staff.
[0025] like Figure 2 and Figure 3 As shown, the movable component 3 includes a sliding frame 31, and four corners of the top of the sliding frame 31 are provided with sliding grooves 32, and a sliding block 33 is slidably installed inside the sliding groove 32, and a buffer spring 34 is fixedly connected to the top of the sliding block 33, and the sand box 4 is movably connected to the top of the buffer spring 34, and buffer springs 35 are movably installed on the front and rear sides of the sliding frame 31, and a mounting plate 36 is fixedly installed on the rear side of the frame body 21, and a high-speed motor 37 is fixedly installed on the bottom of the mounting plate 36, and a turntable 38 is fixedly connected to the outside of the output shaft of the high-speed motor 37, and a push-pull rod 39 connected to the turntable 38 is movably hinged on the rear side of the sliding frame 31.

[0028] By turning on the vacuum fan 66, suction is generated from the bottom of the dust hood 62 through the connecting pipe 67 to suck in the generated dust and transport it into the dust removal box 63 through the connecting pipe 67. The dust is filtered and blocked by the filter screen plate 65 connected to the inner side of the rail 64 in the dust removal box 63, and the air is discharged through the vacuum fan 66, thereby preventing the dust from being inhaled by the staff and affecting their health.
[0029] like Figure 3 As shown, the turntable 38 is disposed between the mounting plates 36 , and a connecting column is disposed on the top of the turntable 38 and is located outside the center of the turntable 38 .
[0030] An opening corresponding to the push-pull rod 39 is formed on the rear side of the frame body 21 , and the push-pull rod 39 is movably sleeved on the outside of the connecting column.
[0031] The connecting column located outside the center of the turntable 38 is connected with the push-pull rod 39, so that when the turntable 38 rotates, the push-pull rod 39 is driven to move to push the sliding frame 31 to move, thereby increasing the shaking force and vibration amplitude of the workpiece and improving the sand falling effect.

[0036] like Figure 4 and Figure 5 As shown, the sealing cover 68 is connected to the rear side of the dust removal box 63 using bolts.
[0037] The sealing cover 68 is installed by bolts and can be disassembled regularly to clean and maintain the filter screen plate 65.
[0038] The following is a detailed description of the working principle of the sand-falling machine that facilitates the rapid cleaning of the sand-shooting holes in the sand box.
[0039] like Figures 1 to 5As shown, a shakeout box 4 with a vibration motor provided on the outside generates vibration with the vibration motor to vibrate the molding sand in the workpiece on the internal shakeout net 5 thereof, so that the molding sand falls from the bottom of the shakeout box 4 into the sand collecting box 1. At the same time, a high-speed motor 37 is turned on, and a turntable 38 located on the inner side of a mounting plate 36 is driven to rotate by the high-speed motor 37. The turntable 38 is connected to a push-pull rod 39 through a connecting column on the turntable 38.

The sliding movement drives the sand-falling box 4 on the buffer spring 34 to slide back and forth synchronously, and the sliding frame 31 drives the sand-falling box 4 to shake back and forth to intensify the shaking amplitude of the workpiece, and cooperates with the vibration motor outside the sand-falling box 4 to make the sand-falling box 4 vibrate and shake sand with a large amplitude, so that the vibration sand-falling effect is better and more efficient. At the same time, dust is generated during the sand-falling process, and the suction force is generated from the bottom of the dust hood 62 by turning on the vacuum pump 66 through the connecting pipe 67 to suck the generated dust into the dust removal box 63 through the connecting pipe 67, and the dust is filtered and blocked by the filter screen plate 65 clamped on the inner side of the clamping rail 64 in the dust removal box 63, and the air is discharged through the vacuum pump 66.
[0040] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
