[0032] Working principle: By gripping the handle 7, the top cover 6 can be removed from the feed funnel 5, allowing molten metal to be poured into the storage tank 4 from the feed funnel 5. Then, the hydraulic cylinder 12 pushes the fixing plate 14 to rise, allowing the lower mold plate 13 to embed into the upper mold plate 9. At this point, the molten metal can enter between the upper mold plate 9 and the lower mold plate 13. When the tank is full, the liquid entry effect can be controlled by the solenoid valve 10. After the brake housing between the upper mold plate 9 and the lower mold plate 13 is formed... The hydraulic cylinder 12 can drive the fixed plate 14 to descend. The descent of the fixed plate 14 can cause the vertical rod 17 to descend and press against the top of the support plate 24. At this time, the spring 21 will be compressed, and the push plate 16 can push the formed brake housing to detach from the surface of the lower mold plate 13, which can automatically demold. After demolding, the lower mold plate 13 can be reset by the hydraulic cylinder 12. At this time, the spring 21 can reset the vertical rod 17. At the same time, the heating ring plate 8 can heat and keep the molten metal inside the storage tank 4.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
