Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2(The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0020] Please see Figure 1-3 This application provides a technical solution for a wax mold recycling and processing device for precision casting production: A wax mold recycling and processing device for precision casting production includes a crushing group 1, a heating group 6 is provided at the bottom of the crushing group 1, and a receiving box 26 is provided at the bottom of the heating group 6. The receiving box 26 is divided into three spaces by two partitions 27, wherein the middle space is a wax liquid recycling space, the two sides are impurity collection spaces, and a receiving drawer 30 is provided in the collection space.

[0021] Specifically, the receiving drawer 30 has a side plate at one end, and a handle is fixed on the side plate. The receiving drawer 30 in the receiving space can collect impurities on the filter screen, making it easier for workers to handle.

[0022] A filter screen group 13 is slidably connected to the bottom of the heating group 6. A replacement screen group 17 is provided on the rear side of the filter screen group 13. Two material replacement support groups 21 are provided above the receiving box 26.

[0023] The filter assembly 13 includes a filter screen 14, a fixing plate 15, and a connecting plate 16. The filter screen 14 is disposed inside the heating assembly 6. The front end of the filter screen 14 passes through the heating assembly 6 and is connected to the fixing plate 15. The rear end of the filter screen 14 is provided with the connecting plate 16, which also passes through the heating assembly 6.

[0024] The rear end of the connecting plate 16 is provided with a strip groove. The filter screen 14 and the connecting plate 16 are slidably connected to the heating group 6. The fixing plate 15 is in contact with the heating group 6. This arrangement makes it easy for workers to pull out the filter screen group 13.

[0025] The replacement mesh assembly 17 includes a second filter screen 18, a second fixing plate 19, and a second connecting plate 20. The second connecting plate 20 is located at the rear end of the first connecting plate 16, the second filter screen 18 is located at the rear end of the second connecting plate 20, and the second fixing plate 19 is located at the rear end of the second filter screen 18. The replacement mesh assembly 17 is placed on the material replacement support assembly 21.

[0026] Specifically, a strip block is provided at the front end of the connecting plate 20 corresponding to the strip groove. The strip block on the connecting plate 20 cooperates with the strip groove on the connecting plate 16, thereby connecting the replacement mesh group 17 with the filter mesh group 13. This pushes the replacement mesh group 17 and pushes the filter mesh group 13 out of the heating group 6 for replacement. This makes it easier for workers to handle the wax and impurities on the filter mesh 14, achieving the effect of replacing the filter mesh without stopping the machine.

[0027] Furthermore, the heating assembly 6 includes an outer shell 7, an inner liner 9, a heating chamber 8, a water inlet pipe 10, a water outlet pipe 11, and a heating rod 12. The inner liner 9 is located inside the outer shell 7, and a heating chamber is located between the inner liner 9 and the outer shell 7. The heating rod 12 is located inside the heating chamber. The water outlet pipe 11 is located on one side of the heating chamber 8, and the water inlet pipe 10 is located at the bottom of the heating chamber 8.

[0028] Specifically, the water in the heating chamber 8 is heated by the heating rod 12, which in turn heats the wax passing through the inner liner 9 to melt it, making it easier to filter the wax.

[0029] Furthermore, a flow guide block 28 is provided inside the inner liner 9, and a support block 29 for supporting the filter assembly 13 is provided below the flow guide block 28.

[0030] Specifically, the guide block 28 can guide the wax liquid to the filter screen assembly 13, and the support block 29 has two units, both of which are set on the inner wall of the inner liner 9, and can support the filter screen 14 on the filter screen assembly 13.

[0031] Furthermore, the crushing unit 1 includes a crushing box 2, a crushing motor 3, and a crushing roller 4. Two crushing motors 3 are provided on the front side of the crushing box 2. The power output end of the crushing motor 3 extends into the interior of the crushing box and is connected to the crushing roller 4. The rear end of the crushing roller 4 is rotatably connected to the crushing box 2.

[0032] With this setup, the two crushing motors 3 are started, one rotating forward and the other in reverse, so that the two crushing rollers 4 crush the wax entering the crushing box 2, thereby improving the melting efficiency of the wax mold.

[0033] Furthermore, the material replacement support group 21 includes a baffle 22, a front support 23, a rear support 24 and an inclined plate 25. The baffle 22 is installed on the receiving box 26. The rear support 24 is installed inside the baffle 22 near the heating group 6. The front support 23 is installed inside the baffle 22 away from the rear support 24. The inclined plate 25 is installed at the bottom of the baffle 22.

[0034] Specifically, the front support 23 can support the fixing plate 15 on the filter assembly 13 or the fixing plate 19 on the replacement mesh assembly 17, and the rear support 24 can support the connecting plate 16 on the filter assembly 13 or the connecting plate 20 on the replacement mesh assembly 17.

[0035] More specifically, the inclined plate 25 can guide the wax and impurities remaining on the filter screen. Workers can scrape off the wax or impurities on the filter screen with a brush and guide them through the inclined plate 25 to the collection drawer 30 in the impurity collection space for collection.

[0036] In use: First, water is injected into the heating chamber 8 through the water inlet pipe 10, and the water in the heating chamber 8 is heated by the heating rod 12 to keep the inner liner 9 at a high temperature. Then, the wax mold enters the crushing box 2 through the feed hopper 5. The two crushing motors 3 are started, one rotating forward and the other rotating in reverse, so that the two crushing rollers 4 crush the wax entering the crushing box 2. The crushed wax is heated by the inner liner 9 to melt the wax. The melted wax falls into the collection box 26 after being filtered by the filter screen group 13.

[0037] When the filter assembly 13 needs to be cleaned and replaced, the strip block on the connecting plate 20 cooperates with the strip groove on the connecting plate 16, thereby connecting the replacement mesh assembly 17 to the filter assembly 13. This pushes the replacement mesh assembly 17, pushing the filter assembly 13 out of the heating group 6 for replacement. This makes it easier for workers to remove wax and impurities from the filter mesh 14, achieving the effect of replacing the filter without stopping the machine.

[0038] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
