[0023] Please see Figures 1 to 5This utility model provides a technical solution: a hot-press casting molding device for processing graphite boat support components, including a base 1, a lower mold 2 fixed on the base 1, an upper mold 3 movably mounted on the top of the lower mold 2, a fixing plate 5 welded to the side of the upper mold 3, a pushing mechanism 11 movably mounted on the fixing plate 5, one end of the pushing mechanism 11 fixedly mounted on the base 1, a fixing bolt 10 rotatably mounted on the fixing plate 5, one end of the fixing bolt 10 movably contacting the side of the pushing mechanism 11, and the upper mold 3 being respectively fixed with... An air inlet pipe 6 and a feeding cylinder 7 are installed. A lifting mechanism 8 is fixedly installed on the top of the feeding cylinder 7. A movable disc 22 is installed on the lifting mechanism 8. The movable disc 22 is movably installed inside the feeding cylinder 7. A feeding pipe 9 is fixedly installed on the side of the feeding cylinder 7. Both the pushing mechanism 11 and the lifting mechanism 8 are linear reciprocating electric push rods. The lifting mechanism 8 pushes the movable disc 22 to move downward. The movable disc 22 seals the feeding pipe 9 while squeezing the material at the bottom of the feeding cylinder 7 downward. Under the squeezing of the movable disc 22, the material is quickly filled into various positions for rapid molding.

[0024] In this embodiment, the bottom of the lower mold 2 has a cavity 12, and a protrusion 13 is fixedly installed inside the cavity 12. The upper mold 3 has a forming cavity 19, and a sealing plate 20 is fixed inside the forming cavity 19. One end of the sealing plate 20 is installed inside the cavity 12. Openings 4 are opened on the sides of both the upper mold 3 and the lower mold 2. A support pipe 16 is fixed to one end of the air inlet pipe 6. The support pipe 16 is fixedly installed inside the upper mold 3. A positioning hole 21 is opened between the upper mold 3 and the support pipe 16. A fixed... Positioning tube 14 is fixedly installed on the lower mold 2. The positioning tube 14 has a through hole 15. A horizontal tube 17 is welded to one end of the positioning tube 14. Both the horizontal tube 17 and the support tube 16 have exhaust holes 18, which are matched with the openings 4. The top of the molding cavity 19 has a feed port 23, one end of which is connected to the feed cylinder 7. The horizontal tube 17 discharges the airflow inside the support tube 16 through the positioning tube 14 from the upper and lower openings 4. The airflow inside the openings 4 facilitates the rapid reduction of the high temperature inside the upper mold 3 and the lower mold 2.

[0025] In use, the pushing mechanism 11 drives the upper mold 3 to be installed on the lower mold 2 via the fixing plate 5. The sealing plate 20 on the upper mold 3 enters the cavity 12 to seal it. The air inlet pipe 6 is connected to an external air pump, and the material is injected into the feed cylinder 7 through the feed pipe 9. After entering the feed cylinder 7, the material falls downwards and falls from the feed port 23 into the molding cavity 19 and the cavity 12. After feeding is completed, the lifting mechanism 8 is activated. The lifting mechanism 8 pushes the movable plate 22 downwards. The movable plate 22 seals the feed pipe 9 and simultaneously moves the feed cylinder downwards. The material at the bottom of the 7th layer is squeezed downwards. Under the pressure of the movable disc 22, the material is quickly filled into various positions for rapid forming. After the workpiece is formed, the external fan is activated to bring the airflow into the air inlet pipe 6. The airflow flows inside the support pipe 16 and enters the positioning pipe 14 through the through hole 15. The airflow enters the horizontal pipe 17 through the positioning pipe 14 and is discharged from the opening 4 through the exhaust holes 18 on the horizontal pipe 17 and the support pipe 16. When discharged, the high temperature inside the upper mold 3 and the lower mold 2 is removed. After the high temperature is reduced, it is easy for the workpiece to be quickly cooled and removed later.
