Description

Technical Field

[0001] The utility model belongs to the technical field of casting molds, and in particular relates to a silica sol precision casting mold cleaning device. Background Art

[0002] Silica sol casting mold is a kind of wax mold made of silica sol and other materials as raw materials. The wax mold is then processed into a mold by slurry hanging and other methods, and then processed into various complex shapes and workpieces with relatively high precision requirements by mold casting.

[0003] During the casting process, a lot of dirt remains in the mold, and the specific dirt is mainly the residual contamination of the molten metal during casting. During use, if the dirt cannot be fully cleaned, it is easy to form uneven positions on the workpiece during the subsequent casting process, and it is easy to cause pores on the workpiece, making the subsequent processing of the workpiece very cumbersome.

[0004] Therefore, during the production and processing process, the mold needs to be cleaned. The specific method is to place the mold in a cleaning container and clean it by immersion cleaning. However, during the cleaning process, it is necessary to increase the flushing force between the mold and the cleaning liquid to increase the cleaning effect.

[0005] However, since the mold has a certain weight, in the process of swinging the mold, the impact and flushing force between the mold and the cleaning liquid is increased, not only is it difficult to swing, but also because the mold production workpieces are often mass-produced, the number of molds used in production is relatively large, and cleaning is very cumbersome.

[0006] Therefore, during the cleaning process, a large number of molds can only be hung on the hanger, and the hanger is lowered by the hoisting hoist until all the molds are immersed in the cleaning liquid for cleaning. However, this cleaning method cannot form a flushing force between the mold and the cleaning liquid, thereby fully cleaning the mold. Utility Model Content

[0007] Based on the above background, the purpose of the utility model is to provide a silica sol precision casting mold cleaning device.

[0008] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0009] A silica sol precision casting mold cleaning device comprises a mold cleaning chamber, and a plurality of mold cleaning mechanisms are rotatably arranged on the top of the mold cleaning chamber;

[0044] Example 1

[0045] like Figure 1-6 As shown, a silica sol precision casting mold cleaning device includes a mold cleaning chamber 1. According to the conventional method, a liquid inlet pipe and a liquid outlet pipe are connected to the mold cleaning chamber 1; the liquid inlet pipe and the liquid outlet pipe are respectively equipped with valves. The cleaning liquid is pumped in and out through the liquid inlet pipe and the liquid outlet pipe.

[0046] The top of the above-mentioned mold cleaning chamber 1 is equipped with a plurality of mold cleaning mechanisms 3 in a rolling manner; specifically, a slide rail 2 is fixedly connected to the top of the mold cleaning chamber 1, and the mold cleaning mechanism 3 includes an outer rolling frame 31 rolling on the slide rail 2 (the specific rolling manner is: a plurality of rollers 311 are assembled and connected on the outer side wall of the outer rolling frame 31; the rollers 311 roll on the slide rail 2 at the top of the mold cleaning chamber 1).

[0047] The outer rolling frame 31 is fixedly connected to an inner annular fixed frame 32, and the inner annular fixed frame 32 is rotatably connected to a cleaning rotating frame 33 (the cleaning rotating frame 33 is annular, and the specific rotation method is: an annular groove is opened on the inner annular fixed frame 32; the cleaning rotating frame 33 is rotatably connected in the annular groove).

[0048] Meanwhile, a plurality of adjusting hanging plates 35 are fixedly connected to the cleaning rotating frame 33 (the adjusting hanging plates 35 are welded to the inner side wall of the cleaning rotating frame 33), and an adjusting hanging plate 37 is fixedly connected to the adjusting hanging plate 35. Specifically, a rectangular opening 351 is opened on the adjusting hanging plate 35, and a fixing screw 37 is fixedly connected in the rectangular opening 351.

[0049] At the same time, the fixed screw 37 is slidably connected with a plurality of hanging slides 38 of the hanging mold (in the working process, in order to adjust the spacing between adjacent hanging slides 38 and ensure that the spacing between the molds is maintained after the molds are hung, the fixed screw 37 is threadedly connected with a plurality of pairs of nuts 371 positioned on both sides of the hanging slide 38). The bottom of the hanging slide 38 is fixedly connected with a hook 381. At the same time, two symmetrically arranged small rollers 382 are assembled and connected to the upper end of the hanging slide 38, and the small rollers roll on the adjustment hanging plate 35. After the mold is hung, during the sliding process, the small rollers 382 are supported and rolled on the adjustment hanging plate 35 to reduce the resistance of sliding adjustment in this way.

[0050] During operation, the mold is hung on the connecting hook 381. In this way, a large number of molds can be hung. After hanging, the hanging slide 38 is slid and adjusted, and the nut 371 is positioned to ensure that sufficient spacing is maintained between the molds.

[0051] The top of the cleaning rotating frame 33 is connected with a rotating motor 36. According to the conventional method, the output shaft of the rotating motor 36 is fixedly installed at the top center of the adjusting hanging plate 35; the top of the rotating motor 36 is fixedly installed with a motor frame 361, and the two ends of the motor frame 361 are respectively fixedly installed with connecting screws (the connecting screws are fixedly installed at the top of the outer rolling frame 31).

[0052] During operation, the rotating motor 36 is turned on. Driven by the rotating motor 36, the cleaning rotating rack 33 rotates with the hanging mold. During the rotation, the flushing force between the mold and the cleaning solution is increased, thereby greatly improving the cleaning effect.

[0053] During the cleaning process, the rolling mold cleaning mechanism 3 carries the mold and rolls on the top of the mold cleaning chamber 1. During the rolling process, the mold is flushed with the cleaning liquid again, and the flushing method further improves the cleaning effect of the dirt on the mold.

[0054] Example 2

[0055] like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 1, the upper cleaning rotating frame 33 is rotatably connected to the inner annular fixing frame 32 through a rolling structure.

[0056] Specifically, the rolling structure includes a plurality of rollers 34 hinged at the top and bottom positions of the cleaning rack 33 (a plurality of grooves for limiting rollers 34 are opened at the top and bottom edges of the cleaning rack 33, and the rollers 34 after cooling are placed in the grooves and limited in the grooves after random thermal expansion), and the rollers 34 roll against the top and bottom positions of the annular groove.

[0057] During operation, driven by the motor, the cleaning rack 33 rotates through the roller 34 structure. This method is not only highly flexible, but also under the resistance of rotation, under the low-speed drive of the motor, all molds follow the rotation, and "drive the cleaning liquid in a stirring manner", thereby greatly improving the cleaning effect of the mold.

[0058] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
