1. What parts does the die casting machine die consist of?

A: the structure of the die casting die can be divided into the following parts according to its function: (as shown below)aluminum die casting machines 

(1)Molding part (dynamic and fixed die casting mold core, molding insert, core pulling, etc.)

(2) Mold base part (movable and fixed mold clamping plate, AB plate, supporting plate and mold foot)

(3) Bypass system (gate sleeve, splitter cone, runner, inlet bypass)

(4) Overflow system (overflow tank, steam exhaust tank)

(5) Ejector mechanism (ejector pin, ejector pin fixing plate, ejector plate, reset lever)

(6) Guide parts (guide post, guide sleeve, middle guide post, middle guide sleeve)

(7) Core pulling mechanism (core pulling slider, inclined guide post, clamping block, spring, etc.)

(8) Others (cooling system, heating system, reinforcing column, etc.)

2. What material is the die casting die made of?

Answer: the die casting die of our company is mainly made of the following Steels:

(1) H13 (heat resistant steel) as front and rear mold core, core pulling core, gate sleeve, shunting cone, etc.)

(2) 45 steel (as a and B plates, sliding blocks, inclined guide posts, etc.)

(3) T8, T10 (guide post, guide sleeve, thimble, reset rod, etc.)

(4) A3 steel (front and rear die clamping plates, supporting plates, thimble plates, die feet, etc.)

3. What is the heat treatment hardness of die casting machine die core? What are the consequences of being too soft and too hard?

Answer: the maximum hardness of mold core heat treatment is hrc45 ~ 48. If the treatment is too soft (lower than hrc43), the die core is easy to collapse, deform and stick during die production; If the treatment is too hard (higher than HRC50), the mold core is easy to crack. After nitriding, the hardness of some parts will reach hrc58-60 (such as gate sleeve, insert, etc.).

4. What are the factors considered when selecting the die casting machine for the die casting die?

Answer: (1) mold installation (i.e. whether the die casting machine can fit the mold is related to the distance between the inner rod of the Golin column and the position of the pressure chamber);

(2) Pouring amount of molten metal (whether the capacity of injection chamber of die casting machine is sufficient);

(3) Clamping force (when setting a reasonable specific pressure, the clamping force is enough to lock the mold);

(4) Injection specific pressure (to ensure casting quality);

(5) Mold opening stroke (able to take out the product).
