The mold is then placed in a sand mold, so that a cavity with the same size as the part is formed in the sand mold. A fluid liquid is then poured into the cavity. After the liquid cools and solidifies, a part with the same shape and structure as the mold can be formed. During the manufacturing process of the mold itself, the burrs around the mold need to be polished.

[0015] The present invention will be further described below in conjunction with the embodiments.

[0017] Further, the toothed disc 4 is circular, and the side surface of the toothed disc 4 is evenly fixedly connected with a tooth block 19, and the side surface of the toothed disc 4 is evenly fixedly connected with a tooth block 20. The tooth blocks 19 and 20 occupy half of the side surface of the toothed disc 4. The number of tooth blocks 19 is less than the number of tooth blocks 20, and the spacing between the tooth blocks 19 is less than the spacing between the tooth blocks 20. The gear 5 is meshed with the tooth block 20, and the top of the contact disc 1 7 is evenly fixedly connected with a vibration ball 10, and the top of the contact disc 2 8 is evenly fixedly connected with a vibration ball 10. The bottom end is evenly and fixedly connected with a vibration column 9, which is cylindrical, and the bottom end of the vibration column 9 is semi-spherical. The vibration ball 10 is a semi-spherical shape, and the vibration column 9 and the vibration ball 10 are spaced apart from each other. The top of the base 1 is fixedly connected with four groups of telescopic rods 21, and the top of the telescopic rod 21 is fixedly connected to the surface of the working bin 2. The surface of the telescopic rod 21 is sleeved with a spring, one end of the spring is fixedly connected to the upper surface of the telescopic rod 21, and the other end of the spring is fixedly connected to the lower surface of the telescopic rod 21.

[0018] During the specific implementation of this embodiment, when the user uses the device, first, the mold to be polished is placed inside the working chamber 2, and the mold is covered with sand and gravel inside the working chamber 2. Then, the device is powered on, and then the motor 6 is controlled to start. The motor 6 drives the gear 5 to rotate, and the gear 5 meshes with the tooth block 20. The gear 5 drives the toothed disc 4 to rotate through the tooth block 20. When the gear 5 meshes and rotates with the tooth block 20 until it meshes with the tooth block 19 again, the gear 5 reciprocates through the tooth block 19 and the tooth block 20 to drive the toothed disc 4 to rotate continuously. The toothed disc 4 is fixedly connected to the contact disc 1 7. The toothed disc 4 drives the contact disc 1 7 to rotate at the same time.

When the gear 5 is meshing and rotating with the tooth block 19, the rotation speed of the toothed disc 4 is increased, and when the gear 5 is meshing and rotating with the tooth block 20, the rotation speed of the toothed disc 4 is reduced. Through different rotation speeds, the speeds at which the vibration ball 10 and the vibration column 9 collide are different. When the speed at which the vibration ball 10 and the vibration column 9 collide is accelerated, the working bin 2 is driven to vibrate violently and quickly. The movement drives the sand and the mold inside the bearing column 3 to vibrate violently, thereby driving the mold to jump through inertia and vibration force to avoid the mold sinking to the bottom and uneven contact of the sand and gravel. The device sets a toothed disk 4 and a gear 5, and a tooth block 19 and a tooth block 20 that reciprocate with the gear 5, so that the working bin 2 is constantly vibrated, and the vibration amplitude is adjusted reciprocatingly, thereby avoiding the mold sinking to the bottom of the working bin 2 due to the influence of gravity, so that the sand and gravel cannot grind the bottom of the mold, thereby affecting the grinding effect. Compared with the traditional vibration grinding device, the grinding effect is improved, the consumption of manual labor is reduced, and the subsequent uneven grinding effect does not require manual grinding again, thereby greatly improving the grinding efficiency.
