Description

Technical Field

[0001] This utility model relates to the field of casting technology, specifically to a casting sand adding mechanism. Background Technology

[0002] Casting is a process in which metal and non-metal sand are melted into a liquid that meets certain requirements and poured into a mold. After cooling and solidification, and cleaning, a casting with a predetermined shape, size and performance is obtained. It is one of the basic processes of modern equipment manufacturing industry. In the casting process, the main types of foundry sand used are quartz sand, sappan sand and Luoyang ore sand. If an auxiliary foundry sand adding mechanism is set up on the casting equipment, the processing efficiency of the casting equipment can be effectively improved.

[0003] The utility model patent with patent number CN 219151491 U discloses a foundry sand adding mechanism. Although it can filter foundry sand through its filter screen, the filtered impurities are still on the top of the filter screen, which makes the top of the filter screen easy to clog. Moreover, the filter screen remains stationary during the filtration process, which further aggravates the risk of foundry sand clogging.

[0004] To address the aforementioned issues, we propose a foundry sand adding mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a foundry sand adding mechanism to address the aforementioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a foundry sand adding mechanism, comprising a feeding pipe, a filter pipe, and a variable diameter guide pipe. The feeding pipe is located at the top of the filter pipe, and the variable diameter guide pipe is located at the bottom of the filter pipe. An upwardly protruding conical filter screen is fixedly provided on the inner wall of the feeding pipe. A vertically downward vibrating rod is fixedly provided on the top inner wall of the conical filter screen. A vibrating housing is fixedly provided at one bottom end of the vibrating rod. A vibrating motor is installed inside the vibrating housing. The side wall of the filter pipe has equidistantly distributed impurity ports. An annular impurity storage tray is fixedly provided on the outer wall of the filter pipe. The bottom inner wall of the impurity ports is flush with the edge of the conical filter screen. The annular impurity storage tray is located at the bottom of the impurity ports.

[0007] Preferably, a baffle ring is fitted onto the outer wall of the filter tube, and two lifting plates are fixedly provided on the side wall of the baffle ring.

[0008] Preferably, a first docking ring is fixedly provided at the bottom of the feeding pipe and the top outer wall of the variable diameter guide pipe, and a second docking ring is fixedly provided at the top and bottom outer walls of the filter pipe. The outer walls of the first docking ring and the second docking ring are provided with docking holes that are evenly distributed, and the inner walls of the docking holes are equipped with matching bolts.

[0009] Preferably, a feeding hopper is fixedly provided on the top outer wall of the feeding pipe.

[0010] Preferably, a flange is fixedly provided on the bottom outer wall of the variable diameter guide pipe.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0012] The vibrating horse drives the vibrating rod to vibrate, which in turn drives the conical filter screen to vibrate. This allows the foundry sand to pass through the conical filter screen quickly, effectively preventing the foundry sand from clogging and improving the efficiency of findingry sand addition. The conical filter screen can efficiently block impurities at the edge. Under the action of vibration, the impurities fall into the annular storage tray through the impurity port, which facilitates the separation of foundry sand from impurities and further prevents impurities from clogging this utility model.
