Description

Technical Field

[0001] The utility model relates to the technical field of casting, in particular to a film-coated sand shell casting separation device. Background Art

[0002] In the foundry industry, coated sand shell casting is a widely used process. Coated sand has the advantages of high strength, good disintegration, and low gas emission. It can produce castings with high dimensional accuracy and good surface quality. However, after casting is completed, the coated sand shell needs to be separated from the casting. Traditional separation methods mainly rely on manual knocking or mechanical vibration. These methods have problems such as low efficiency, high labor intensity, and easy damage to castings.

[0003] However, during the use of the existing coated sand shell casting separation device, for large and heavy castings or when the sand shell is particularly strong, it may take a long time for vibration to achieve the separation effect, and some sand shells may remain, requiring secondary processing, thereby reducing the overall efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a coated sand shell casting separation device with high separation efficiency and quality, long service life and simple operation, so as to solve the technical problems of long time and low efficiency in separating the coated sand shells of large and heavy castings and castings with particularly strong sand shells in existing devices.

[0005] In order to solve the above technical problems, the solutions adopted by the present invention are as follows:

[0006] A film-coated sand shell casting separation device comprises a fixed seat, an impact mechanism, a vibration mechanism and a separation box; the fixed seat is provided with a bracket and a fixing plate; the bracket is provided with a plurality of roots, the bottom end of which is fixedly connected to the fixed seat, and the top end of which is fixedly connected to the fixing plate; the separation box is located between the fixed seat and the fixing plate; the vibration mechanism is fixedly installed inside the fixed seat, and the top end is connected to the separation box;

[0007] The impact mechanism includes a motor bracket, a motor, a rotating shaft 1, and an impact paddle; the motor bracket is fixedly connected to the top end of the fixed plate; the motor is fixedly mounted on the motor bracket; the top end of the rotating shaft 1 is fixedly connected to the output end of the motor, and the bottom end passes through the fixed plate and extends into the separation box; a plurality of impact paddles are provided, evenly distributed at the lower end of the rotating shaft 1; all of the impact paddles are located inside the separation box; the impact paddles at the bottom end of the rotating shaft 1 are driven by the rotation of the motor to rotate, thereby crushing the sand shell of the casting and separating it from the casting;

[0008] The vibration mechanism is provided with a vibration component and a buffer component; the vibration component includes a dual-axis motor, a fixing frame, a second rotating shaft, an eccentric wheel and a protective shell; the output shafts at both ends of the dual-axis motor are fixedly connected to the second rotating shaft; the eccentric wheel is fixedly mounted on the second rotating shaft; the protective shell is located on the outside of the eccentric wheel and is connected to both ends of the dual-axis motor; the dual-axis motor is fixedly connected to the separation box through the fixing frame fixedly mounted on the outer wall of the top end, and the two output shafts of the dual-axis motor rotate to drive the second rotating shaft to rotate, thereby rotating the eccentric wheel, so that the dual-axis motor rotates The fixed frame drives the separation box to move, thereby achieving the purpose of vibrating the separation box; the buffer component is fixedly connected to the bottom end of the outer wall of the dual-axis motor. When the dual-axis motor vibrates, there will be a downward impact, and the buffer component can play a role in buffering and resetting. The dual-axis motor is a device that uses electromagnetic principles to achieve output motion. It consists of a group of permanent magnets and two magnetic axes. Its working principle is that when current passes through the motor, two sets of magnetic fields are generated in the permanent magnet. The magnets on each magnetic axis are facing in opposite directions. These magnetic forces work together to enable the motor to obtain rotational force and form a continuous and stable rotation output.

[0009] Furthermore, the fixing base is provided with a plurality of telescopic rods (I) and a plurality of springs (I); each spring is mounted on the telescopic rod (I); the bottom ends of the telescopic rods (I) and springs (I) are fixedly connected to the fixing base, and the top ends are fixedly connected to the separation box. When the separation box is vibrated by the dual-axis motor of the vibration mechanism, the springs (I) are squeezed, generating elastic force. Under the action of this elastic force, the springs (I) rebound upward, causing the dual-axis motor and the separation box to rebound upward, thus providing a buffer and reset for the machine, reducing wear on the machine and increasing its service life.

[0010] Furthermore, the buffer assembly includes a second protective shell, a second telescopic rod, a second spring, and a buffer seat; the second protective shell is fixedly mounted within the fixed seat; the second telescopic rod is fixedly mounted on the bottom inner wall of the second protective shell; the second spring is sleeved on the second telescopic rod; the tops of the second telescopic rod and the second spring are fixedly connected to the buffer seat; and the buffer seat is fixedly connected to the bottom end of the outer wall of the dual-axis motor. When the dual-axis motor vibrates, the downward force squeezes the second spring and the second telescopic rod within the buffer assembly, and the spring rebounds, buffering and resetting the vibrating dual-axis motor through the buffer seat.

[0011] Furthermore, the separation box is equipped with a coarse filter, a fine filter, and a discharge port; the coarse and fine filters are fixedly installed inside the separation box from top to bottom; the impact paddle is located inside the separation box, directly above the coarse filter; and the discharge port is located on the outer wall of the separation box and connected thereto. The impact paddle breaks up the sand shell of the casting. The separation box is driven to vibrate by a dual-axis motor, and the separated coated sand is screened through the coarse and fine filters. Larger coated sand particles are blocked by the fine filter, while fine coated sand is screened out through the fine filter. The screened coated sand flows out of the discharge port.

[0012] The working principle of this utility model is as follows:

[0013] When in use, the casting wrapped with the coated sand shell is placed in the separation box, and the motor is started. The motor drives the impact paddle to rotate through the rotating shaft 1 to separate large and complex-shaped castings and crush the sand shell of the casting to separate it from the casting. The double-axis motor is started. The double-axis motor drives the eccentric wheel to rotate through the rotating shaft 2 on both sides. When the eccentric wheel rotates, it will generate a large centrifugal force, thereby generating vibration, driving the separation box to vibrate, so that the sand shell is quickly loosened and separated from the casting, and is screened through the coarse filter and the fine filter. Large pieces of coated sand particles will be The fine coated sand is blocked by the coarse filter and screened out from the fine filter. The screened coated sand flows out from the discharge port, vibrating and screening the material in the separation box. During vibration, the buffer component located below will be subjected to downward pressure, and the spring 2 in the buffer component will be squeezed under the action of pressure, thereby generating elastic rebound. The spring 1 on the outer wall of the telescopic rod on the top of the fixed seat is subjected to pressure during the vibration of the separation box. The spring 1 is squeezed and generates elastic rebound, causing the dual-axis motor and the separation box to rebound upward, thereby buffering and resetting the machine.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. The utility model drives the impact paddle to rotate through the motor and the rotating shaft in the impact mechanism, effectively breaking the sand shell of the casting and realizing the rapid separation of the casting and the sand shell. The dual-axis motor of the vibration mechanism drives the separation box to vibrate, further promoting the separation of the coated sand and the casting, thereby improving the separation efficiency and quality.

[0016] 2. The telescopic rod 1 and spring 1 structure of the utility model, as well as the telescopic rod 2 and spring 2 in the buffer assembly, act together on the dual-axis motor and the separation box. When the dual-axis motor vibrates, the spring 1 and the spring are squeezed to generate elastic force, causing the separation box and the dual-axis motor to rebound upward, playing a role of buffering and resetting, effectively reducing the wear of the machine and extending the service life of the machine.

[0017] 3. The utility model uses the coarse filter and fine filter inside the separation box, and then combines the vibration mechanism to vibrate the separated coated sand, and screens the coated sand through the coarse filter and fine filter, thereby improving the sorting accuracy of the coated sand and improving the utilization rate and recovery quality of the material.

[0030] The working principle of this embodiment is as follows:

[0031] During use, the casting wrapped with the coated sand shell is placed in the separation box 4, and the motor 201 at the top of the fixed plate 102 is started.

The dual-axis motor 311 is started, and the dual-axis motor 311 drives the eccentric wheel 314 to rotate through the rotating shaft 2 313 on both sides. When the eccentric wheel 314 rotates, a large centrifugal force is generated, thereby generating vibration, driving the separation box 4 to vibrate, so that the sand shell is quickly loosened and separated from the casting, and the material in the separation box 4 is vibrated and screened.
