Temperature control scheme for 350 ℃ oil mold temperature machine (die casting mold temperature machine)
Introduction to Die Casting: Pressure casting is referred to as die casting for short; A casting method in which molten alloy liquid is poured into a pressure chamber to fill the mold cavity of a steel mold at high speed and solidify under pressure to form a casting.
Die casting process: The liquid metal is first cast at a low speed or at a high speed and filled into the mold cavity. The mold has a movable cavity surface, which is pressurized and forged along with the cooling process of the liquid metal, not only eliminating the shrinkage defects of the blank, but also making the interior of the blank
Classification of die casting machines:
The heating conditions of the press chamber of a die casting machine can be divided into two categories: a hot press chamber and a cold press chamber.
Due to the different placement positions of the press chamber and the mold, cold chamber die-casting machines can be divided into three types: vertical, horizontal, and fully vertical die-casting machines.
Die casting is divided into magnesium alloy, aluminum alloy, and zinc alloy by material.
Selection of heating power:
The heating power is generally selected based on the mold locking force of the press casting machine. The mold temperature machine is relatively mature in the die casting industry, and can be directly selected for customers without calculation.
1. The heating power and pump power of the mold locking force below 150t are 12KW and 1HP, respectively
2. The mode locking force of 150-300t is equipped with a heating power of 18-24KW and a pump power of 2HP
3. The mold locking force of 300-500t is equipped with a heating power of 36KW and a pump of 4HP
4. If the mold locking force is above 500t, the model selection shall be conducted through calculation.
If the customer requires different temperatures for dynamic and fixed molds, choose a dual loop mold warmer.
