The fixed mold 4 is one of the important components in the die-casting mold for forming the casting. It cooperates with the moving mold 8 to form the cavity of the casting. The support frame 6 provides support and fixation for the cylinder 7 and the moving mold 8, ensuring their stability during operation. The cylinder 7 extends and retracts, realizing the opening and closing action of the moving mold 8 and the fixed mold 4, completing the die-casting process of the casting. The moving mold 8 and the fixed mold 4 cooperate to form a complete die-casting cavity. Driven by the cylinder 7, it opens and closes with the fixed mold 4, realizing the die-casting of the casting and absorbing heat.
