DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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.

[0027] See also Figures 1 to 5 A casting dewaxing device includes a kettle body 1, which is used to provide a space for dewaxing the casting to facilitate dewaxing activities.

[0028] A driving motor 11 is provided inside the kettle body 1, a rotating shaft 10 is fixedly mounted on the output end of the shaft of the driving motor 11, and a rotating plate 5 is fixedly mounted on the rotating shaft 10;

[0029] When the drive motor 11 is started, the shaft 10 can be rotated. The rotation of the shaft 10 drives the rotating plate 5 to rotate synchronously, and then the casting on the rotating plate 5 can revolve around the center of the shaft 10.

[0030] The rotating plate 5 is evenly and evenly rotated with a placement plate 6, a fixing rod 20 is fixedly installed at the center of the placement plate 6, a mounting plate 21 is fixedly installed on the fixing rod 20, and an outer ring gear 13 is fixedly installed on the mounting plate 21;

[0031] Preferably, in order to ensure the stability of the casting during the dewaxing process, a necessary clamping device can be used when the casting is placed on the placement tray 6. Since it is a prior art, it is not described in detail.

[0032] The tray 6 is provided with a channel for the wax to drip, thereby realizing the dewaxing activity.

[0033] When the outer ring gear 13 is rotated, the rotation of the outer ring gear 13 can drive the outer ring gear 13 to rotate, and then the casting on the outer ring gear 13 can rotate on its own, thereby further improving the dewaxing effect.

[0034] A driving mechanism adapted to the outer ring gear 13 is provided inside the kettle body 1, and the driving mechanism can drive the corresponding outer ring gear 13 to rotate;

[0035] The interior of the kettle body 1 is also provided with an adjustable spraying mechanism, which can spray steam or hot water to achieve dewaxing activity by bringing these substances into contact with the casting.

[0036] The driving mechanism includes a lifting frame 14, which is fixedly mounted on the kettle body 1. A fixing plate 15 is fixedly mounted on the other end of the lifting frame 14. A stepping motor 17 is provided on the fixing plate 15. A connecting shaft 18 is fixedly mounted on the output end of the shaft of the stepping motor 17, and a driving gear 19 is fixedly mounted on the other end of the connecting shaft 18.

[0037] The activation of the lifting frame 14 can change the height of the driving gear 19, and then when the rotating plate 5 rotates, the driving gear 19 is in a retracted state. At this time, the driving gear 19 is not on the motion trajectory of the outer ring gear 13, so that the rotating plate 5 can rotate smoothly. When it reaches the specified position, the lifting frame 14 rises, so that the driving gear 19 rises synchronously, and then the driving gear 19 contacts and meshes with the outer ring gear 13. At this time, by starting the stepping motor 17 to rotate the driving gear 19, the outer ring gear 13 can be rotated through the meshing relationship, thereby completing the self-rotation activity of the casting.

[0038] The fixing plate 15 is also provided with an observer 16 . The existence of the observer 16 allows the angle of the corresponding position observer 16 to be observed, so that the angle of the driving gear 19 can be adjusted in a targeted manner, so that the meshing activity can be carried out smoothly.

[0039] Preferably, in order to ensure the alignment effect, the gears on the outer ring gear 13 and the driving gear 19 can be bevel gears.

[0040] The driving gear 19 is in meshing relationship with the corresponding outer ring gear 13 .

[0041] The adjustable spray mechanism includes a threaded rod 12, which is rotatably mounted on the kettle body 1. The threaded rod 12 is connected to a nut pair 22 by a thread, and a mounting bracket 23 is fixedly mounted on the nut pair 22. A handwheel 24 is fixedly mounted on one end of the threaded rod 12.

[0042] A hollow plate 7 is rotatably mounted on the mounting frame 23, and nozzles 8 are evenly and equidistantly inlaid on the hollow plate 7. The rotation between the mounting frame 23 and the hollow plate 7 is a hovering rotation, which is generally achieved through corresponding hinges and other designs. Since it is a prior art, it is not described in detail.

[0043] When the nut pair 22 is rotated by the handwheel 24, the nut pair 22 translates on the threaded rod 12, and the mounting bracket 23 moves synchronously. The distance between the nozzle 8 and the casting can be adjusted according to actual needs, which is convenient for daily use. The hollow plate 7 can be rotated, and the nozzle 8 can adapt to the shape of the casting, which is more convenient to use.

[0044] A collection box 9 is movably installed inside the kettle body 1, which is located directly below the corresponding one. The wax or hot water after dewaxing will accumulate inside the collection box 9, which is convenient for collection activities;

[0045] A sealing door 2 is rotatably mounted on the kettle body 1, an observation window 3 is embedded in the sealing door 2, and a handle 4 is fixedly mounted on the sealing door 2. The sealing door 2 can be opened and closed by the handle 4, which is convenient for placing the casting. The operator can observe the situation inside the kettle body 1 through the sealing door 2, which is convenient for targeted adjustment.

[0046] The working process of the present invention is as follows: first, the nozzle 8 is adjusted, and the nut pair 22 is rotated by the hand wheel 24, and the nut pair 22 is translated on the threaded rod 12, and then the mounting bracket 23 is moved synchronously. The distance between the nozzle 8 and the casting can be adjusted according to actual needs, which is convenient for daily use, and the hollow plate 7 can be rotated, and then the angle of the nozzle 8 can adapt to the shape of the casting, which is more convenient to use.

[0047] Then the castings are placed in by rotating the rotating plate 5 and placing the corresponding castings on the four placement trays 6 on it. In order to ensure the stability of the castings during the dewaxing process, necessary clamping devices can be used when placing the castings on the placement trays 6. Then the sealing door 2 is closed to prevent hot air leakage inside the kettle body 1.

[0048] Afterwards, the driving motor 11 is started to rotate the rotating plate 5 90°. At this time, a casting is located at the position of the nozzle 8. Then the lifting frame 14 rises, so that the driving gear 19 contacts and engages with the outer ring gear 13. At this time, by starting the stepping motor 17 to rotate the driving gear 19, the outer ring gear 13 can be rotated through the meshing relationship, thereby completing the self-rotation of the casting, so that different surfaces of the casting can be evenly contacted with the ejected gas or liquid, and the dewaxing effect can be guaranteed.

[0049] After one casting completes the dewaxing activity, the driving gear 19 is retracted by the lifting frame 14. At this time, the driving gear 19 is not on the motion trajectory of the outer ring gear 13, so that the rotating plate 5 can rotate smoothly. After continuing to rotate 90°, the other casting is at the position of the nozzle 8. Repeat the operation to make it rotate on its own and then the dewaxing activity can be carried out.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
