The wax liquid needs to be stirred before being added to the wax injection machine to ensure that the various states of the wax liquid are suitable for entering the wax injection machine for wax injection molding operations.

[0003] In traditional technology, the wax liquid is placed inside a tank and a set of stirring rods are installed inside the tank to stir the wax liquid. This operation is convenient and quick, but the wax liquid needs to be heated before stirring. If the heating is not complete, solid particles will appear in the wax liquid. In addition, the wax liquid is sticky, making the inner wall of the tank difficult to clean.

[0004] Therefore, it is particularly important to improve the existing stirring device for investment casting wax liquid, design a new stirring device for investment casting wax liquid to solve the above-mentioned technical defects, and improve the practicality of the overall stirring device for investment casting wax liquid.

[0022] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Example:

[0024] See also Figures 1-5 , the utility model provides a technical solution:

[0025] A stirring device for investment casting wax liquid comprises a tank body 1, a lid 2 is plugged in and connected to the top of the tank body 1, a reinforcing ring 3 is fixedly connected to the outside of the tank body 1, the bottom end of the tank body 1 is fixedly connected to a supporting foot 4, an extension rod 5 is fixedly connected between the supporting feet 4, the top end of the inner side of the tank body 1 is fixedly connected to a receiving plate 6, the bottom of the receiving plate 6 is fixedly connected to a funnel 7, the bottom of the funnel 7 is fixedly connected to an extension tube 8, the interiors of the funnel 7 and the extension tube 8 are interconnected, by placing the supporting feet 4 in a specified position and forming a triangular design between the supporting feet 4 by the extension rod 5, the tank body 1 is made more stable, by pulling the lid 2 out of the interior of the tank body 1, and then exposing the outside of the tank body 1 to the outside, and then pouring the wax liquid into the interior of the funnel 7.

[0026] For further information, see Figure 2 、 Figure 3 、 Figure 4 and Figure 5In this embodiment, a filter screen 9 is provided on the inner wall of the funnel 7, and a sleeve 10 is fixedly connected to the bottom of the extension tube 8. The internal rotation connection of the extension tube 8 is a limit rod 11. The top of the limit rod 11 extends to the inside of the funnel 7, and the bottom of the limit rod 11 extends to the outside of the sleeve 10. The bottom of the limit rod 11 is fixedly connected to a linkage rod 12. The wax liquid is filtered and screened through the filter screen 9 to prevent the wax liquid from containing fixed particles due to incomplete heating, thereby affecting the product quality. The liquid will directly fall into the interior of the tank body 1 through the filter screen 9, and the particulate matter will adhere to the outside of the filter screen 9, and then the linkage rod 12 will be rotated, and the limit rod 11 will be driven to rotate by the linkage rod 12.

[0027] For further information, see Figure 2 In this embodiment, the top of the limiting rod 11 is fixedly connected to a collar 13, and the outside of the collar 13 is fixedly connected to a scraper 14. The scraper 14 is designed with a sloped structure. The scraper 14 fits the filter screen 9. When the limiting rod 11 rotates, the collar 13 will drive the rotation to follow, so that the scraper 14 can circulate in the filter screen 9, accelerating the filtration of solid particles. Moreover, each time the scraper 14 rotates one circle, the solid particles will be gathered. When a certain amount is gathered, the fixed particles will flow into the interior of the extension tube 8 and finally drip into the interior of the sleeve 10.

[0028] For further information, see Figure 3 、 Figure 4 and Figure 5 In this embodiment, a blade 15 is fixedly connected to the inside of the sleeve 10 and located on the outside of the limit rod 11. A guide tube 16 is fixedly connected to the outside of the sleeve 10. The guide tube 16 and the inside of the sleeve 10 are interconnected. There are four groups of guide tubes 16, and the four groups of guide tubes 16 are distributed at equal intervals. The rotation of the limit rod 11 will drive the blade 15 to rotate, crushing the fixed particles, and residual liquid on the funnel 7 will fall into the inside of the sleeve 10, and the centrifugal force generated by the rotation of the blade 15 will finally flow out from the guide tube 16.

[0029] For further information, see Figure 3 and Figure 4 In this embodiment, a reciprocating groove 17 is provided at the top of the linkage rod 12. A moving ring is slidably connected to the inside of the reciprocating groove 17. Blades 18 are fixedly connected to the outside of the moving ring. The blades 18 are distributed at equal intervals. When the linkage rod 12 rotates, the reciprocating groove 17 rotates with it. At the same time, the moving ring slides inside the reciprocating groove 17, so that the moving ring drives the blades 18 to move up and down and rotate to mix and stir the wax liquid.

[0030] For further information, see Figure 3 and Figure 4In this embodiment, a sliding sleeve 19 is slidably connected to the middle of the outside of the linkage rod 12, and a fixed sleeve 20 is fixedly connected to the bottom end of the linkage rod 12. The outside of the sliding sleeve 19 and the fixed sleeve 20 are fixedly connected to mounting seats, and the mounting seats are distributed at equal intervals. The inside of the mounting seat is rotatably connected to a connecting rod 21, and the end of the connecting rod 21 away from the mounting seat is rotatably connected to a scraper rod 22. The bottom of the scraper rod 22 is designed with an arc-shaped structure. When the blade 18 spirally descends, it drives the moving ring to squeeze the sliding sleeve 19, so that the sliding sleeve 19 slides on the outside of the limit rod 11, and then the connecting rod 21 is expanded, and the scraper rod 22 is expanded outward, fitting with the inside of the tank body 1, and cleaning the wax liquid on the inner wall of the tank body 1. In this reciprocating operation, the scraper rod 22 can cooperate with the stirring operation and also clean the tank body 1.

[0031] After the filter 9 is closed, the filter 11 is opened, and the filter 12 is opened, so that the filter 12 can be filtered and filtered. The liquid flows into the interior of the extension tube 8 and finally drips into the interior of the sleeve 10. The rotation of the limit rod 11 will drive the blade 15 to rotate and crush the fixed particles. Residual liquid on the funnel 7 will fall into the interior of the sleeve 10, and the centrifugal force generated by the rotation of the blade 15 will finally flow out from the guide tube 16. The linkage rod 12 rotates, and the reciprocating groove 17 will follow its rotation. At the same time, the movable ring slides inside the reciprocating groove 17, so that the movable ring drives the blade 18 to move up and down and rotate to mix and stir the wax liquid. When the blade 18 spirally descends, it will drive the movable ring to squeeze the sliding sleeve 19, so that the sliding sleeve 19 slides on the outside of the limit rod 11, and then the connecting rod 21 is expanded, and the scraper rod 22 is expanded outward to fit the inside of the tank body 1 and clean the wax liquid on the inner wall of the tank body 1. With such reciprocating operation, the scraper rod 22 can cooperate with the stirring operation and also clean the tank body 1.
