Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of die-casting machines, in particular to a multi-station head plate and a die-casting machine. Background Art
[0002] Existing multi-station injection molding systems employ multiple injection mechanisms arranged along the circumference of the die-casting machine's platen. These mechanisms independently inject molten metal into the mold cavity, which is fixed between the die-casting machine's platens. This reduces the flow path of the molten metal within the cavity and thus avoids potential problems when molding large and complex die-castings. For example, prolonged molding can cause the molten metal to cool and solidify within the cavity. The solidified portion can no longer be compacted by the injection cylinder's pressure, resulting in numerous shrinkage cavities in the die-casting, affecting its density.
[0003] However, the multiple feed ports on the die-casting machine head plate will affect the rigidity of the head plate, which will easily cause the head plate to deform when the die-casting machine is clamped. In addition, the multi-station head plate is not suitable for the traditional single-shot mechanism. Users cannot mold different types of die-casting parts by replacing the single-shot mechanism or the multi-shot mechanism. Utility Model Content
