Description

Technical Field

[0001] This utility model relates to the field of casting shell making technology, specifically a sand-spraying device for casting shell making. Background Technology

[0002] Sand spraying for casting shell preparation is a key step in the shell preparation process of investment casting. It refers to the process of uniformly spraying or spreading sand particles onto the coating layer on the surface of the wax model after applying refractory coating, so that the sand particles and coating adhere to form the shell layer.

[0003] The existing Chinese patent announcement number CN212469653U, entitled "A Sand-Laying Equipment for Casting Shells," explicitly states in its abstract that "This utility model discloses a sand-laying equipment for casting shells, comprising a shell, a perforation on one side of the top of the shell, a sand inlet pipe fixedly installed inside the perforation, a sand distribution pipe fixedly installed at the bottom of the sand inlet pipe and connected to the sand inlet pipe, multiple sand-laying nozzles fixedly installed at the bottom of the outer wall of the sand distribution pipe and connected to the sand distribution pipe, a shaft seat fixedly installed at the top of one side of the shell, a drive motor rotatably connected inside the shaft seat, a turntable fixedly installed on the output shaft of the drive motor, multiple fixed grooves fixedly installed at one end of the turntable, a cover door at the top of one end of the shell, and a sand outlet at the middle of the bottom end of the shell. In this utility model, the drive motor drives the turntable to rotate, and simultaneously controls the electric push rod to push the drive motor to swing up and down, increasing the range of motion of the casting mold to be sand-laden, making the sand-laden surface of the casting mold more uniform, and the sand-laden equipment can significantly improve the sand-laden efficiency."

[0004] However, this technology requires workers to open the cover door to install the casting mold. After the sanding is completed, the equipment needs to be stopped, and then workers need to open the cover door again, take out the casting mold inside, and then reinstall the casting mold that needs to be sanded. This makes the operation not only cumbersome but also very inefficient when continuously sanding multiple casting molds. Utility Model Content

[0005] The purpose of this invention is to provide a sand-laden equipment for casting shell making, so as to solve the problem mentioned in the background art that the efficiency is greatly affected during the continuous sand-laden process of multiple casting molds.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A sand-laden equipment for casting shell making includes a base, and an installation component is provided on the top of the base;

[0008] The mounting assembly includes a mounting ring, inside which a rotating disk is rotatably mounted, and mounting grooves are provided around the rotating disk. An electric telescopic rod is provided on one side of the mounting ring.

[0009] In a preferred embodiment of this utility model, a recycling tank is placed on the base, and a filter screen is installed inside the recycling tank.

[0010] In a preferred embodiment of the present invention, a rotating shaft is rotatably provided on one side of the rotating disk, a first motor is provided inside the rotating shaft, and the rotating shaft is provided on the drive shaft of the first motor.

[0014] In a preferred embodiment of this utility model, an annular cover is provided on the bottom telescopic end of the electric telescopic rod, and a sand spray nozzle is provided inside the annular cover.

[0015] In a preferred embodiment of this utility model, a sand inlet pipe is provided on one side of the top of the annular cover, and the sand inlet pipe is connected to and communicates with the sand spray nozzle.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0017] Beneficial effects: The casting molds are installed sequentially in four fixed slots. A second motor drives a second bevel gear to rotate, which in turn rotates the rotating disk 90° each time. One installation slot is positioned directly below the annular cover. An electric telescopic rod pushes the annular cover onto the installation slot, and sand is sprayed onto the casting mold through a sand spray nozzle. After sand spraying, the annular cover is lifted, and the rotating disk rotates 90°, moving the sand-sprayed casting mold to the front.

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] Please refer to Figures 1-4This utility model discloses a sand-laden casting shell-making device, comprising a base 1, which serves as the bottom structure of the device and supports the overall structure. A mounting assembly is mounted on the top of the base 1, including a mounting ring 11, which is fixedly mounted above the base 1. A rotating disk 12 is rotatably mounted inside the mounting ring 11. Ball bearings 3 are rolled along the connection side between the mounting ring 11 and the rotating disk 12. The mounting ring 11 and the rotating disk 12 do not directly contact each other; the rotating disk 12 is supported by the ball bearings 3, and the rolling of the ball bearings reduces friction during rotation. A recovery trough 13 is placed on the base 1, and a filter screen 14 is detachably installed inside the recovery trough 13. Sand falling during sand lamination passes through the mounting trough 2 and enters the recovery trough 13, where it is collected. Large particles are filtered by the filter screen 14. The electrical equipment in the device is controlled uniformly by an intelligent controller.

[0027] The rotating disk 12 has mounting grooves 2 around its perimeter, which are used to install the casting mold. A rotating shaft 22 is rotatably mounted on one side of the rotating disk 12. A first motor 21, which is a stepper motor, is mounted inside the rotating shaft 22. The rotating shaft 22 is mounted on the drive shaft of the first motor 21. A turntable 23 is mounted outside the rotating shaft 22. The turntable 23 has multiple fixing grooves 24. The structure of the turntable 23 and the fixing grooves 24 adopts the turntable and fixing groove structure on the turntable in the background technology patent. That is, the casting mold is installed in the mounting groove 2 through the fixing grooves 24. When sanding is performed, the first motor 21 drives the turntable 23 to rotate, thereby ensuring the sanding effect of the casting mold. The first motor 21 rotates an integer number of times.

[0028] A first bevel gear 33 is provided on the outer side of the top of the rotating disk 12, and a second motor 31 is provided on the other side of the mounting ring 11. The second motor 31 is a stepper motor, and a second bevel gear 32 is provided on the drive shaft of the second motor 31. The second bevel gear 32 meshes with the first bevel gear 33, that is, the second motor 31 drives the second bevel gear 32 to rotate. Through gear transmission, the rotating disk 12 rotates 90° each time. An electric telescopic rod 4 is provided on one side of the mounting ring 11. An annular cover 41 is provided on the telescopic end of the electric telescopic rod 4. A sand spraying nozzle 42 is provided inside the annular cover 41. A sand inlet pipe 43 is provided on one side of the top of the annular cover 41. The sand inlet pipe 43 is connected to and communicates with the sand spraying nozzle 42. Whenever the rotating disk 12 rotates 90°, the mounting groove 2 on one side is directly below the annular cover 41. The annular cover 41 is pushed by the electric telescopic rod 4 to cover the mounting groove 2. At this time, sand enters through the sand inlet pipe 43 and is sprayed out through the sand spraying nozzle 42, thereby spraying sand onto the casting mold.

[0029] The working principle of this utility model is as follows: The casting mold is installed in the mounting groove 2 through the fixing groove 24. Casting molds are then installed in all four fixing grooves 24 in sequence. The second motor 31 drives the second bevel gear 32 to rotate, which in turn rotates the rotating disk 12 by 90° each time. After each 90° rotation, one side of the mounting groove 2 is directly below the annular cover 41. The electric telescopic rod 4 pushes the annular cover 41 to cover the mounting groove 2. At this time, sand enters through the sand inlet pipe 43 and is sprayed out through the sand spray nozzle 42, thus spraying sand onto the casting mold. The sand falling through the sand spray passes through the mounting groove 2. The material enters the recycling tank 13 for collection, and large particles are filtered through the filter screen 14. The first motor 21 drives the turntable 23 to rotate, thus ensuring the sand coating effect of the mold. After sand coating is completed, the annular cover 41 is lifted, and the turntable 12 rotates 90°, thereby moving the sand-coated mold to the front. Sand coating stops when the annular cover 41 is lifted, and the installation groove 2 and the mold are at the bottom of the annular cover 41. At this time, subsequent molds can be sand-coated quickly, and the operator only needs to continuously pick up and put away the sand in front. Compared with the existing equipment, it is more convenient to operate and can effectively speed up the sand coating efficiency.
