[0002] Moulds are various molds and tools used in industrial production to obtain the required products by methods such as injection molding, blow molding, extrusion, die-casting or forging, smelting, and stamping. In short, moulds are tools used to make shaped objects. This tool is composed of various parts, and different moulds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the material being formed. It is known as the "mother of industry".

[0003] For example, Chinese patent application number CN202222982517.8 discloses a durable graphite mold. The utility model has a simple structure and is easy to install. The outer retaining ring and the inner retaining ring prevent the inner wall of the outer graphite mold and the outer wall of the inner graphite mold from continuously contacting the outside air, thereby ensuring the heat conduction path between the outer graphite mold, the boron nitride cylinder and the inner graphite mold. The inner graphite mold can be replaced repeatedly, and the outer graphite mold has a long service life.

[0004] In the above scheme, although the purpose of extending the service life is achieved, the workpiece needs to be pried from the bottom with a rod after the mold is closed in order to be taken out, which is very inconvenient. In order to solve the above problems, we designed a graphite mold for casting. Utility Model Content

The protection scope of the utility model is not limited to the following.

[0023] See also Figure 1-2 The utility model embodiment proposes a graphite mold for casting, including a lower mold 1 and an upper mold 2. The lower mold 1 is provided with a molding groove 3, and a bottom plate 7 is provided in the molding groove 3. The shape and size of the bottom plate 7 are adapted to the shape and size of the molding groove 3. The lower mold 1 is provided with a cavity 4, and the cross section of the cavity 4 is convex. The cavity 4 is communicated with the molding groove 3. The bottom plate 7 is connected with an ejector plate 6 through a buffer structure. The ejector plate 6 is provided with an inclined slide groove 8. The upper side wall of the inclined slide groove 8 is inclined. An inclined support rod 10 is slidably connected in the inclined slide groove 8. The upper end of the inclined support rod 10 is inclined. A hydraulic cylinder 5 is fixedly connected to the side wall of the cavity 4. The inclined support rod 10 is fixedly connected to the telescopic end of the hydraulic cylinder 5. The upper mold 2 is provided with a liquid injection port 19 that is arranged through.

[0024] See also Figure 1 The buffer structure includes a buffer groove 12, which is opened on the ejection plate 6. A plurality of buffer springs 13 are fixedly connected to the side wall of the buffer groove 12. A connecting plate 14 is fixedly connected to the upper ends of the plurality of buffer springs 13. The connecting plate 14 is fixedly connected to the bottom side wall of the bottom plate 7. The elastic force of the buffer spring 13 reduces the impact force on the bottom plate 7 when the solution is poured, thereby reducing the protection of the bottom parts of the bottom plate 7.

[0025] See also Figure 1A rubber pad 15 is fixedly connected to the side wall of the connecting plate 14, and the side wall of the rubber pad 15 is against the side wall of the buffer groove 12. The rubber pad 15 can increase the friction between the buffer groove 12, thereby reducing the reaction force brought by the buffer spring 13, which is equivalent to the damping effect.

[0026] See also Figure 1 A groove 11 is provided on the bottom side wall of the cavity 4, and a moving wheel 9 is provided in the groove 11. The moving wheel 9 is fixedly connected to the bottom end of the tilting support rod 10 to enhance the supporting force of the tilting support rod 10 and facilitate the left and right movement of the tilting support rod 10.

[0027] See also Figure 1 Two limiting grooves 17 are provided on the lower mold 1, and two limiting rods 16 are fixedly connected to the bottom side wall of the upper mold 2 to prevent the upper mold 2 from moving left and right.

[0028] See also Figure 1 The upper mold 2 is provided with a through-hole 20 . The solution contains a certain amount of gas, and the gas is discharged through the vent hole 20 .

[0029] See also Figure 1 Two handles 18 are fixedly connected to the upper side wall of the upper mold 2 to facilitate taking the upper mold 2 down or putting it down.

[0030] The working principle of the utility model is: when in use, the two limit rods 16 are inserted into the two limit grooves 17, the upper mold 2 and the lower mold 1 are merged together, and the solution is poured into the shaping groove 3 through the injection port 19. The solution is cast downward and will cause a certain impact force on the bottom end of the bottom plate 7. The impact energy can be weakened by the buffer spring 13, and the impact force of the components at the bottom end of the bottom plate 7 is reduced. After the shaping is completed, the upper mold 2 is removed by the handle 18, and then the hydraulic cylinder 5 is started. When the telescopic end of the hydraulic cylinder 5 moves left and right, it moves left and right with the inclined support 10, so that the ejection plate 6 can be moved up and down, so that the bottom plate 7 can be pushed upward or downward, so that the workpiece can be ejected out of the shaping groove 3, which is convenient for the workpiece to be taken out.
