Description

Technical Field

[0001] This utility model relates to the field of sand casting technology, and in particular to a cleaning mechanism for sand casting molds. Background Technology

[0002] A casting mold is a tool used to create a part's structural shape in advance using other easily moldable materials. The mold is then placed in a sand mold, creating a cavity in the sand mold that matches the dimensions of the part. A fluid liquid is then poured into this cavity, and after the liquid cools and solidifies, a part with the exact same shape and structure as the mold is formed. Casting molds are an important part of the casting process.

[0003] When casting is completed and the cast parts are removed from the existing sand casting mold, some casting sand remains inside the mold. If too much casting sand accumulates inside the mold, it will affect subsequent mold casting and thus affect the production quality of mold casting. Therefore, a cleaning mechanism for sand casting molds is proposed to solve the above problems. Utility Model Content

[0028] It should be noted that when cleaning the sand casting mold, the sand casting mold is first placed inside the cleaning box 1, so that the sand casting mold is positioned on the right side of the support module 27. Then, the drive cylinder 25 is started, and the piston rod of the drive cylinder 25 will drive the movable plate 26 to move to the right. The movable plate 26 and the support module 27 can fix the sand casting mold. At this time, the drive DC motor 22 is started, and the output shaft of the drive DC motor 22 will drive the rotating shaft 23 to rotate. The rotating shaft 23 will drive the waterproof cover 24 to rotate, and the waterproof cover 24 will drive the drive cylinder 25 to rotate. The drive cylinder 25 will drive the movable plate 26 to rotate. Under the action of the support module 27, the movable plate 26 will drive the sand casting mold to rotate. Then, the sand casting mold can be cleaned by the recovery spray assembly 4. During cleaning, the waterproof cover 24 can protect the drive cylinder 25 to prevent water from entering the drive cylinder 25.

[0029] In an optional embodiment, the support module 27 includes a support block 271 and a support disk 272. The support block 271 is located on the right side wall of the inner cavity of the cleaning box 1, and the support disk 272 is rotatably connected to the left side of the support block 271. The movable disk 26 corresponds to the support disk 272.

[0030] It should be noted that the right side of the sand casting mold can be supported by the support block 271 and the support plate 272. At the same time, the sand casting mold can be fixed by the support block 271 and the movable plate 26. The rotation of the support block 271 can cause the movable plate 26 to drive the sand casting mold to rotate.

[0031] In an optional embodiment, the filter assembly 3 includes two mounting grooves 31, two mounting sliders 32, a filter plate 33, and two sets of fixing modules 34. The two mounting grooves 31 are located on the left and right side walls of the inner cavity of the cleaning box 1. The two mounting sliders 32 are slidably connected to the inside of the two mounting grooves 31 respectively. The filter plate 33 is located on the opposite side of the two mounting sliders 32 and is adapted to the cleaning box 1. The two sets of fixing modules 34 are respectively located on the top of the two mounting grooves 31.

[0032] It should be noted that when the sand casting mold is cleaned by the recycling spray assembly 4, water and residual casting sand will fall together. During the falling process, the residual casting sand can be filtered by the filter plate 33, so that the casting sand remains on the top of the filter plate 33. The filter plate 33 can be quickly installed and removed by the two mounting grooves 31 and the two mounting sliders 32, which facilitates the cleaning or replacement of the filter plate 33.

[0033] In an optional embodiment, both sets of fixing modules 34 include a threaded groove 341, a threaded rod 342, and a knob 343.

[0034] It should be noted that when installing the filter plate 33, the two mounting sliders 32 are slidably connected inside the two mounting grooves 31. Then, the knob 343 is rotated, which drives the threaded rod 342 to rotate. When the threaded rod 342 is threaded into the threaded groove 341, the mounting sliders 32 can be fixed by the threaded rod 342 and the threaded groove 341, thereby fixing the filter plate 33. When the filter plate 33 needs to be disassembled, the knob 343 is rotated in the opposite direction, which drives the threaded rod 342 to rotate in the opposite direction. When the threaded rod 342 is disengaged from the threaded groove 341, the filter plate 33 can be pulled forward, thereby disassembling the filter plate 33 for easy cleaning or replacement.

[0035] In an optional embodiment, the recycling spray assembly 4 includes a water tank 41, multiple drain holes 42, a pump body 43, a pumping pipe 44, a connecting pipe 45, a diversion pipe 46, and multiple nozzles 47. The water tank 41 is located at the bottom of the cleaning tank 1. The multiple drain holes 42 are all opened in the inner bottom wall of the cleaning tank 1 and extend to its bottom. The multiple drain holes 42 are connected to the water tank 41. The pump body 43 is located at the top of the cleaning tank 1. The pumping pipe 44 is connected to the inlet pipe of the pump body 43 and the other end is connected to the inside of the water tank 41. The diversion pipe 46 is located in the inner top wall of the cleaning tank 1. The connecting pipe 45 is connected to the outlet pipe of the pump body 43 and the other end is connected to the diversion pipe 46. The multiple nozzles 47 are all connected to the bottom of the diversion pipe 46 and are evenly distributed. The top of the connecting pipe 45 is connected to a water filling pipe, and a valve is provided inside the water filling pipe.

[0036] It should be noted that when cleaning the sand casting mold, the water filtered by the filter plate 33 will fall into the water tank 41 through multiple drain holes 42. Then, the pump body 43 will be started, and the pump body 43 will draw water from the water tank 41 through the water suction pipe 44. At the same time, the water will be sent into the diversion pipe 46 through the connecting pipe 45 and sprayed out through multiple nozzles 47. The water sprayed out by the nozzles 47 will clean the sand casting mold. Water can be added to the connecting pipe 45 through the water addition pipe. When the water is insufficient or water is consumed, water can be added.

[0037] In an optional embodiment, the front of the cleaning box 1 is hinged with a door 5, and a controller is provided on the outer end face of the cleaning box 1.

[0038] It should be noted that the filter plate 33 can be easily disassembled through the box door 5. At the same time, a sealing ring is provided on the inside of the box door 5 to ensure the sealing of the box door 5 after it is closed, preventing water leakage through the box door 5 when cleaning the sand casting mold. The drive DC motor 22, drive cylinder 25 and pump body 43 are all electrically connected to the controller, and the drive DC motor 22, drive cylinder 25 and pump body 43 can be controlled through the controller.

[0039] Working principle:

[0040] In use, the cleaning mechanism for this sand casting mold involves first opening the door 5 and placing the sand casting mold inside the cleaning box 1. Then, the drive cylinder 25 is activated, causing the movable plate 26 to move to the right. When the right side of the movable plate 26 and the left side of the support plate 272 abut against the two sides of the sand casting mold, the mold is secured. Next, the pump body 43 is activated, and water is sprayed through multiple nozzles 47 to clean the sand casting mold. At the same time, the drive DC motor 22 is activated, which, under the action of the movable plate 26 and the support plate 272, drives the sand casting mold to rotate, making the cleaning more thorough. The cleaned casting sand and water are filtered through the filter plate 33, leaving the residual casting sand at the top of the filter plate 33. The remaining water falls into the water tank 41 through multiple drain holes 42. Then, the pump body 43 is activated, and with the action of the water pumping pipe 44, connecting pipe 45, and diversion pipe 46, the water resources can be recycled, saving a significant amount of resources.

[0041] 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
