[0001] The utility model relates to the technical field of powder die-casting equipment, in particular to a powder die-casting molding machine. Background Art

[0002] Powder die-casting machine is a kind of equipment used to manufacture metal or alloy parts. It usually uses powdered materials as raw materials and mixes them into a uniform mixture. The mixture is then injected into a pre-designed mold to form parts of the desired shape. During the molding process, pressure is transmitted to the powder material through the mold wall, causing it to gradually solidify and eventually become the desired shape. It is not only suitable for the manufacture of metal products, but can also be used for the molding of other materials such as plastics and ceramics.

Although the products can be demolded, a large number of motors or cylinders are required, which increases the manufacturing cost. Therefore, the present application provides a powder die-casting molding machine to meet the demand. Utility Model Content

In this process, the pressure rod 21 squeezes the airbag 11 when it moves in the direction of the turntable 20, and the airbag 11 is squeezed to allow the air to be transported along the conveying pipe 10 to multiple air pipes 12, and then transported along the air pipe 12 to the inside of the air storage cylinder 13, and the air transported to the bottom of the top column 14 The push column 14 is pushed to move upward, driving the collar 15 upward, and sending the die-cast parts upward out of the pressing groove 7. At this time, the discharge shell 24 pushes the parts on the bottom plate 1, pushing them away from the collar 15 and out of the bottom of the pressing block 6. At this time, the pressure rod 21 is also separated from the air bag 11 while moving in the direction of the turntable 20, so that the air bag 11 is no longer squeezed, and the air bag 11 automatically resets, driving the collar 15 to reset downward as well, and the second cylinder 25 stops, and the storage box 16 can feed the material to the discharge shell 24 through the feeding pipe 23, and the powder material is directly injected into the interior of the pressing groove 7. After completion, the second cylinder 25 starts to reset, allowing the storage box 16 to reset, and the pressure rod 21 rotates one circle along the turntable 20 to reset, completing the powder die-casting. The advantage of this is that only the second cylinder 25 is needed to achieve demolding and feeding, and there is no need to use too many motors and cylinders, saving manufacturing costs.

[0033] By providing the wheels 26, the material storage box 16 is more convenient to be pushed by the second cylinder 25, and the friction is reduced.
