die casting mould water cooling system

die casting mould water cooling system

Die casting mould water cooling mean to tool a cooling water way to let the water help reduce the die casting mould core and die casting mould cavity temperature. Water cooling speed is faster than are cooling ,could help the die casting mould producing effciently.

Die casting mould with water cooling system ,its mould structure is always more complex. But considering water cooling structure could help the mould reduce the die casting mould cycle time , some middle and big die casting mould will adopt water cooling system.

Die casting mould cooling

Die casting mould cooling

As we know, die casting mould core and cavity will touch high temperature metal alloy directly in the die casting working process. Every mould opening, the forming part will touch outer cold air ,which will cause the die casting mould thermal fatigue and affect the die casting mould life. In addition, thus frequent thermal fatigue will also has influence on the die casting molding part forming cycle time and the die casting molding parts size dimension precision. That is why die casting mould must design a good cooling system.

Since different metal alloy has different melting point. The die casting mould cooling system design needs to take the die casting molding  technology into consideration. A good die casting mould cooling system will help to increase die casting mould life and meanwhile reduce the forming cycle to realize larger production.

Aluminum alloy die casting

Aluminum alloy die casting

The characters of Aluminum alloy and its elements function.

Advantage of Aluminum alloy
•Small density (2.5-2.9 g/cm 3)
•Good corrosion resistance
•Good abrasion resistance
•Good thermal conductivity
•Good electrical conductivity
•Good cutting property
Defect of Aluminum alloy casting
•Al-Si alloy is easily to cause mold sticking.
•Erode metal crucible
•High shrinkage rate leads to shrinkage cavity

Why die casting mold to be useless?

Die casting mold useless

As we all know, the mould life of die casting mould is shorter than common injection mould. And the die casting mould to be useless is the main causes. Below are the external and internal causes why the die casting mould is easily to be useless?

External causes which lead to the useless of die casting mould:

-Casting temperature;

-Die casting mould didn’t be pre-heated.

-Releasing coating spraying volume;

-The die casting machine tonnage can’t meet the mould clamping force

-Casting pressure is too high.

-The flow speed of inner gate is too fast.

-Cooling system and the casting process do not work at the same time.

-The casting part size, shape, wall thickness, and releasing coating type are also the causes of die casting mould useless.

Internal causes which lead to the useless of die casting mould:

-The mould steel quality.

-The mould steel forging technology.

-The design of the mould structure.

-The design of the casting system structure.

-The mould inner stress which is caused during the mould tooling process.

-Mould heat treatment technology.
