Abstract
The utility model discloses a pressure die casting machine which comprises a die assembly mechanism and a press-shoot mechanism. A cover half and a moving die are fixedly arranged inside the die assembly mechanism, wherein the cover half is opposite to the moving die. The press-shoot mechanism injects molten metal into a mould cavity composed by the cove half and the moving die through a nozzle. The nozzle of the press-shoot mechanism is arranged on the side surface of the mould cavity, and the nozzle is used for injecting the molten metal from a die assembly position of the moving die and the cover half into the mould cavity in the side direction. The pouring of the nozzle is from the side surface of the mould cavity. A sprue gate is short and waste of the sprue gate is little. The ratio of a product after being once die casting to the wastes is about 6 to 4. Due to the fact that the using ratio of materials is high, output is improved and energy is saved accordingly. Due to the fact that the waste is little, the quality of the product is improved accordingly. Because a water gap is placed in the side surface, the opening stroke of the water gap is short, and therefore the die sinking speed is improved, in other words, the production efficiency is improved.
