Improved pressure chamber structure of die-casting machine

The utility model discloses an improved pressure chamber structure of a die-casting machine. The improved pressure chamber structure comprises a pressure chamber body, wherein a splash-proof feeding port which makes the molten metal enter the pressure chamber body more quickly is arranged in the radial direction of the pressure chamber body; the feeding port comprises an inlet end and an outlet end, and the inlet end is larger than the outlet end in size. By means of the improved pressure chamber structure, it is guaranteed that magnesium liquid can quickly enter the pressure chamber body, the molten metal cannot be cooled easily, the fluidity of the molten metal is improved, and therefore die-casting forming quality is improved; meanwhile, the magnesium liquid can be prevented from splashing out, so that an operator is prevented from being scalded, potential safety hazards are reduced, and the operation environment is improved.
