Description

Technical Field

[0001] The utility model relates to the technical field of die-casting machines, and in particular to a material pipe temperature control device for a die-casting machine. Background Art

[0002] Die casting is a precise production process, but there are many factors that can affect the final intrinsic quality requirements of die castings. In the die casting process, the material tube is the bridge between the die casting machine and the mold. Usually, the aluminum liquid is transported to the machine side furnace through the material bag after melting, and the material is poured into the material tube by the action of the manipulator. In this process, the temperature drop is often caused by the contact between the aluminum liquid and the inner wall of the material tube, thus forming a chill layer on the inner wall surface of the material tube; during die casting, the movement of the plunger will cause it to peel off the surface and enter the casting along with the melt, thereby reducing the strength or internal structure of the casting. There will be quality risks such as leakage and fracture for castings with high airtightness or strength requirements. Therefore, the probability of forming a chill layer is usually reduced by increasing the temperature of the aluminum liquid.

[0003] With respect to the above-mentioned related technologies, the inventors believe that increasing the temperature of molten aluminum will lead to disadvantages such as increased smelting costs and reduced tube life. Utility Model Content
