Die casting mold design

(Summary description)The die-casting mold consists of two parts, the covering part and the movable part, and the part where they combine is called the parting line.

The die-casting mold consists of two parts, the covering part and the movable part, and the part where they combine is called the parting line. In hot chamber die casting, the cover has a gate, while in cold chamber die casting it is an injection port. Molten metal can enter the mold from here, and the shape of this part matches the injection nozzle in hot chamber die casting or the injection chamber in cold chamber die casting. The movable part usually includes a push rod and a runner. The so-called runner is the channel between the gate and the cavity through which molten metal enters the cavity. The cover part is usually attached to the fixed or front platen, while the movable part is attached to the movable platen. The cavity is divided into two cavity inserts, which are separate parts that can be bolted off or installed relatively easily from the mold.

The mould is specially designed so that the casting remains in the moving part when the mould is opened. In this way, the push rod of the movable part will push the casting out. The push rod is usually driven by the pressure plate. It will accurately drive all the push rods with the same amount of force at the same time, so as to ensure that the casting is not damaged. When the casting is pushed out, the platen retracts all the push rods in preparation for the next die casting. Since the casting is still in a high temperature state when it is demolded, only a sufficient number of push rods can ensure that the average pressure on each push rod is small enough to not damage the casting. However, the pushrod still leaves marks, so it must be carefully designed so that the position of the pushrod does not affect the operation of the casting too much.
