Description

Technical Field

[0001] This utility model belongs to the field of casting riser technology, and particularly relates to casting riser structure. Background Technology

[0002] A casting riser is an additional section added to the top or side of a casting during the casting process to prevent defects. The main function of a casting riser is to prevent defects such as shrinkage cavities, porosity, and depressions in the casting. By compensating for the shrinkage during solidification, it ensures that the casting has a complete external shape and internal structure.

[0003] Existing casting risers cannot intercept slag and oxides mixed in the molten metal, allowing slag and oxides to enter the mold directly from the casting riser, thus affecting the quality of the casting. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0005] The casting riser structure includes a left side and a right side. An outer frame is provided in the channel formed by the merging of the left and right sides, and an assembly is installed between the left and right sides. A filter screen is fixedly connected to the inner wall of the outer frame, and a connecting rod is fixedly connected to the top of the outer frame. A hook is fixedly connected to the end of the connecting rod away from the outer frame, and the hook is suspended between the left and right sides.

[0006] As a preferred embodiment of the above technical solution, the left and right sides of the part that are close to each other are provided with a receiving groove and a hanging groove, the receiving groove and the hanging groove are connected, and the connecting rod and the hook are respectively placed inside the receiving groove and the hanging groove.

[0007] As a preferred embodiment of the above technical solution, the side wall of the suspension groove is provided with a positioning groove, and the outer ring of the hook is fixedly fitted with a positioning plate, the positioning plate being located inside the positioning groove.

[0008] As a preferred embodiment of the above technical solution, the assembly includes a positioning shaft and a locking block. One end of the positioning shaft is fixedly connected to the outer wall of the right side, and one end of the locking block is fixedly connected to the outer wall of the left side. A locking plate is rotatably sleeved on the outer ring of the positioning shaft, and the locking plate engages with the locking block.

[0009] As a preferred embodiment of the above technical solution, a baffle is threaded to one end of the positioning shaft away from the right side, an elastic part is fixedly connected to one side of the baffle, and the end of the elastic part away from the baffle is fixedly connected to the clamping plate.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. In this invention, as the molten metal enters the mold through the channel between the left and right sides, the filter screen intercepts the slag and oxides mixed in the molten metal, thereby improving the yield and the quality of the castings.

[0012] 2. This utility model allows for easy disassembly and assembly of the left and right sides via assembly parts, making it convenient to remove the filter screen for cleaning and reuse. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] Example

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the casting riser structure includes a left side 11 and a right side 12. An outer frame 20 is provided in the channel formed by the merger of the left side 11 and the right side 12, and an assembly 30 is installed between the left side 11 and the right side 12. A filter screen 21 is fixedly connected to the inner wall of the outer frame 20, and a connecting rod 22 is fixedly connected to the top of the outer frame 20. A hook 23 is fixedly connected to the end of the connecting rod 22 away from the outer frame 20, and the hook 23 is suspended between the left side 11 and the right side 12.

[0022] Specifically, as the molten metal enters the mold through the channel between the left side 11 and the right side 12, the filter screen 21 intercepts the slag and oxides mixed in the molten metal, improving the yield and the quality of the casting. The left side 11 and the right side 12 can be easily disassembled and assembled through the assembly 30, making it easy to remove the filter screen 21 for cleaning and reuse.

[0023] like Figure 2 and Figure 3 As shown, the left side 11 and the right side 12 are provided with a receiving groove 13 and a hanging groove 14 on the side that are close to each other. The receiving groove 13 and the hanging groove 14 are connected. The connecting rod 22 and the hook 23 are respectively placed inside the receiving groove 13 and the hanging groove 14.

[0024] Specifically, there are two sets of receiving slots 13 and hanging slots 14, located on both sides of the left side 11 and right side 12 channels, respectively.

[0025] like Figure 2 and Figure 3 As shown, a positioning groove 15 is provided on the side wall of the suspension groove 14, and a positioning plate 24 is fixedly sleeved on the outer ring of the hook 23. The positioning plate 24 is located inside the positioning groove 15.

[0026] Specifically, through the cooperation of the positioning plate 24 and the positioning groove 15, the filter screen 21 will not fall directly from the channel of the left side 11 or the right side 12 after the left side 11 and the right side 12 are separated, thus preventing the molten metal remaining on the filter screen 21 from splashing onto the operators nearby.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the assembly 30 includes a positioning shaft 31 and a locking block 33. One end of the positioning shaft 31 is fixedly connected to the outer wall of the right side part 12, and one end of the locking block 33 is fixedly connected to the outer wall of the left side part 11. The outer ring of the positioning shaft 31 is rotatably fitted with a locking plate 32, and the locking plate 32 engages with the locking block 33.

[0028] Specifically, the card plate 32 will rotate around the positioning shaft 31. When the card plate 32 and the card block 33 are engaged, the left side 11 and the right side 12 cannot be separated. When the card plate 32 and the card block 33 are separated, the left side 11 and the right side 12 can be separated.

[0029] like Figure 4 As shown, a baffle 34 is threaded to one end of the positioning shaft 31 away from the right side portion 12. An elastic part 35 is fixedly connected to one side of the baffle 34. The end of the elastic part 35 away from the baffle 34 is fixedly connected to the clamping plate 32.

[0030] Specifically, the elastic part 35 uses, but is not limited to, a torsion spring. Through the force of the elastic part 35, the locking plate 32 will be pushed closer to the locking block 33 without any external interference, so that it will always be engaged with the locking block 33.

[0031] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
