"In the current machining process, there are many castings with the same shape on one side and a special design on the other side. If a die-casting machine that can die-cast quickly is optimized so that one side is cooled while the other side is casting, the casting efficiency can be greatly improved. For the above problems, there may already be technical means to solve them in the prior art, but this case wants to provide an alternative or replacement technical solution. Utility Model Content

The die-casting machine base 1 is responsible for carrying the die-casting machine frame 2 and the die-casting hydraulic rod 3, and the softened material is poured on the current die-casting coupling mold 5. The die-casting hydraulic rod 3 runs to press the pressure rod mold 4 to the corresponding coupling mold 5 below to complete the current die-casting operation. After the die-casting hydraulic rod 3 shrinks, the die-casting hydraulic rod 3 is moved horizontally to the top of the coupling mold 5 on the other side through the positioning cycle transverse movement structure. After the die-casting material is poured, the die-casting operation is carried out, and the die-casting on the other side is mechanically processed.
