[0025] The present invention will now be described in further detail with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.
[0026] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.
[0027] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0028] After casting is completed, it is usually located inside the mold shell and is inconvenient to remove. (This is in conjunction with...) Figures 1 to 3 , Figure 5 As shown, a mold setter for easy demolding of castings includes a fixed frame 1, a mold shell 2 on the fixed frame 1, a mold shell 3 on the top of the mold shell 2, and a demolding assembly inside the mold shell 2. The demolding assembly includes a push plate 4 slidably disposed inside the mold shell 2. The fixed frame 1 has a through hole 23 communicating with the mold shell 2. The bottom of the push plate 4 has a sealing sleeve 24 connected to the telescopic end of a cylinder 5. The sealing sleeve 24 matches the through hole 23. The design of the sealing sleeve 24 can reduce the gap at the connection. The cylinder 5 is located directly below the fixed frame 1. The telescopic end of the cylinder 5 passes through the bottom of the fixed frame 1 and is connected to the push plate 4. Shell plate 6 and shell plate 7 are hinged on the push plate 4. There are two shell plates 6 and two shell plates 7. The two shell plates 6 are symmetrically hinged on both sides of the push plate 4. The shell plates 7 are hinged on the other two sides of the push plate 4. The length of the shell plate 7 is less than the length of the shell plate 6.
[0029] After the casting cools and solidifies, the mold shell 2 3 is removed, and the cylinder 5 is started to drive the push plate 4 to rise until the push plate 4 is completely pushed out of the mold shell 1 2. At this time, the shell plate 1 6 and shell plate 2 7 that restrict the casting open and quickly separate from the casting, improving the demolding efficiency of the casting. The separate design of the mold shell 1 2 and mold shell 2 3 makes it easier for the casting to be removed from the mold shell.
[0030] The natural cooling time of castings is relatively long. To shorten the cooling time and reduce the production cycle, in conjunction with the attached... Figure 2 and Figure 4 As shown, the fixing frame 1 is equipped with a cooling assembly for cooling the casting. The cooling assembly includes a cooling cavity 8 surrounding the mold shell 2. A water tank 9 is located below the fixing frame 1 on one side of the cylinder 5. A water pump 10 is provided on the upper surface of the water tank 9. A water pipe 11 and a water pipe 12 are connected to the water pump 10. One end of the water pipe 11 is connected to the cooling cavity 8, and one end of the water pipe 12 is connected to the water tank 9. A drain pipe 21 connected to the cooling cavity 8 is provided on the mold shell 2. The drain pipe 21 is located at the bottom of the cooling cavity 8, and the water pipe 11 is located at the top of the cooling cavity 8. A water valve 22 is provided on the drain pipe 21.
[0031] After the casting is poured, during the static cooling process, the water pump 10 pumps the water in the water tank 9 to the cooling chamber 8. As a highly efficient cooling medium, water can quickly absorb the heat of the casting, thereby achieving rapid cooling and shortening the production cycle. After cooling is completed, the water valve 22 can be opened to drain the water in the cooling chamber 8.
[0032] To improve casting production quality, reduce the gap between mold shell 1 (2) and mold shell 2 (3), and improve casting quality, in conjunction with the attached... Figure 1 , Figure 3 and Figure 6 As shown, the upper surface of the first mold shell 2 is provided with positioning grooves 13 at the four corners, and the second mold shell 3 is provided with positioning rods 14 that match the positioning grooves 13. The upper surface of the second mold shell 3 is provided with injection ports 15. Rotating tubes 16 are hinged to the outer walls on both sides of the first mold shell 2. Multiple sliding rods 17 are inserted into the rotating tubes 16. One end of the sliding rod 17 located outside the rotating tube 16 is connected to a fixing clamp 18, and the other end of the sliding rod 17 is connected to a sliding plate 19. The sliding plate 19 slides inside the rotating tube 16. A spring 20 is sleeved on the sliding rod 17, and the two ends of the spring 20 abut against the sliding plate 19 and the top wall of the rotating tube 16, respectively.
[0033] Align and insert the positioning rod 14 of mold shell 2 3 with the positioning groove 13 of mold shell 1 2, and then rotate the rotating tube 16 to a position perpendicular to the fixing frame 1. At this time, the fixing clamp 18 can firmly and tightly fix the mold shell 2 3 above the mold shell 1 2 under the elastic action of the spring 20, so as to avoid the displacement of the mold shell 2 3 during the casting solidification process and ensure the quality of the casting.
[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
