Description

Technical Field

[0001] The utility model relates to the technical field of pouring suspension devices, in particular to a suspension device used for pouring metal castings. Background Art

[0002] Casting refers to the method of melting solid metal into liquid and introducing it into a casting mold cavity with a specific shape, and then cooling and solidifying it to obtain parts or blanks. It is currently a relatively mature metal heat processing process. In the casting process of metal castings, it is necessary to pour the metal liquid, and the pouring ladle is a common equipment in the pouring field. When in use, the metal liquid is inside the pouring ladle, and then the staff uses a suspension device to lift the pouring ladle through the suspension device and move it to the specified position.

[0003] Chinese Patent Publication No. CN218619803U A suspension device for casting, which can fix the casting ladle from four angles through the cooperation of a suspension rod, a set block, a threaded rod, a limit slot and a stabilizing block, thereby improving the stability of the casting ladle when it is lifted, avoiding shaking during lifting and causing splashing of high-temperature liquid, thereby avoiding safety hazards and improving the safety of the device when used.

[0004] Although the above patent can fix the casting ladle and make it stable when hoisted, it is necessary to align the lifting rod with the set block when fixing the casting ladle. In order to save time, a separate person is required to manually participate in the alignment process, which will increase the labor cost. In addition, the above patent uses a reset spring to restore the moving block at the corresponding position to its original position. Since the reset spring is in a stretched state most of the time, it is difficult for the reset spring to return to the state before use. In addition, the above patent cannot realize the pouring of the casting liquid in the casting ladle. Utility Model Content
