Mold base is mostly made of cast steel, ductile iron and medium carbon steel. Such as QT550, QT600, S50C.

Question 2: What materials are commonly used for die casting dies? Generally, 3Cr2W8V or H 13 is used for core wires.

The mold blank is generally 45.

Question 3: What material is used for aluminum die casting mold? Magnetic core H 13 is also a common material widely used. Our aluminum molds basically use 8407. Of course, this is not absolute. The life of die-casting die depends largely on the heat treatment process. Strict and reasonable heat treatment process can greatly improve the life of the die. When the processing conditions permit, the processing of the core is usually: quenching and tempering-rough machining-quenching treatment +2 or 3 tempering-final forming finishing-stress relieving treatment and nitriding. . . .

Question 4: What materials are commonly used for die casting dies? Die-casting molds are divided into: mold blank and mold meat.

Mould embryo: Generally, it is the ace material.

Molded meat: generally used: 84 18 or 8407 is better, which is better than 100, and almost uses 2344ESR.

Question 5: What material is used for the core of die casting mould at present? In China, the most common and durable material for manufacturing die-casting dies is 3Cr2W8V.

Question 6: What materials are used for general aluminum alloy die casting dies? The most commonly used steel is 3Cr2W8V.

Question 7: The common materials of die casting die are mainly non-ferrous alloys, while ferrous metals (steel, iron, etc.). ) It is rarely used due to the problem of mold materials. Among non-ferrous alloy die castings, aluminum alloy is the most widely used, followed by zinc alloy. The following is a brief introduction to non-ferrous metal die casting. (1), classification of die-casting nonferrous alloys: lead alloy with constrained shrinkage, mixed shrinkage and free shrinkage -0.2-0.3%, 0.3-0.4%, 0.4-0.5%, low melting point alloy, tin alloy and zinc alloy -0.3-0.4%, 0.4-0.6%, 0.0. Al-Cu series Al-Mg series-0.5-0.7% 0.7-0.9% 0.9-1%high melting point alloy Al-Zn series magnesium alloy -0.5-0.7% 0.7-0.9-65448. 3mm simple structure, complex structure, simple structure, complex structure, aluminum alloy, aluminum-silicon series, 6 10-650℃, 640-680℃, 600-620℃, 6 10-650℃, aluminum-copper series, 630-660. -690℃ aluminum-zinc series 590-620℃ 620-660℃ 580-620℃ 600-650℃ zinc alloy 420-440℃ 430-450℃ 400-420℃ 420-440℃ magnesium alloy 640-680℃ 660-. 80℃ 900-930℃ 900-950℃ Silicon Brass 900-920℃ 930-970℃ 91940℃ 910-940℃ Note: ① The casting temperature is generally measured by the temperature of molten metal in the holding furnace. ② The casting temperature of zinc alloy should not exceed 450℃ to avoid coarse grains.

Question 8: What steel is commonly used in die casting dies? 3Cr2W8V is the longest used and most commonly used steel for die casting dies in China.

Question 9: What material is used for die casting core?

Die casting dies can be selected according to workpiece materials, workpiece order quantity and product requirements.

The common, most commonly used and cheapest die-casting die steel is domestic H 13, which is divided into electric furnace and electroslag. National standard steel is relatively better, the composition is basically up to standard, and the price is relatively expensive.

There is another kind called 3Cr2W8V (chromium, tungsten and vanadium), which has good heat resistance and is suitable for aluminum alloy die casting, and some of it is also used for copper die casting (I don't know the effect of copper die casting), and the price is moderate.

Japan's SKD-6 1 is better, the price is about twice that of the national standard H 13, the toughness is better, other properties are basically better than H 13, it is more suitable for mass production, and the polishing effect of the mold is better than that of domestic materials.

There is also 8407, Sweden's one win and one hundred, and its performance is also very superior. Die-casting die rarely cracks and has long service life.

Others are not commonly used, such as Austrian Egret W302 and Japan FDAC.

In a word, there is not much difference in the main components of the above die-casting die steel, but there are differences in the purity of raw materials, the addition of special components and the production technology of die materials. You can choose the right mold material according to your own requirements.

Question 10: What steel should be used for die casting dies? Generally, die casting die steel is used. die steel

Die steel can be roughly divided into three types: (cold-working die steel), (hot-working die steel) and (plastic die steel), which are used for forging, stamping, die cutting and die casting. Because of the different uses and complicated working conditions of various molds, the steel used for molds should have high hardness, strength, wear resistance, sufficient toughness, high hardenability and hardening ability according to the working conditions of the molds manufactured by them. Due to different uses and complex working conditions, the performance requirements of die steel are also different.

Cold working dies include cold stamping die, wire drawing die, drawing die, stamping die, winding die, winding plate, cold heading die and cold extrusion die. The cold working die is made of steel. According to the working conditions, they should have high hardness, strength, wear resistance, sufficient toughness, high hardenability, hardening ability and other technological properties. The alloy tool steel used in this kind of application generally belongs to high carbon alloy steel, and the carbon mass fraction is greater than 0.80%. Chromium is an important alloying element of this kind of steel, and its mass fraction is usually less than 5%. However, for some die steels with high wear resistance and small deformation after quenching, the highest chromium content can reach 13%. In order to form a large number of carbides, the highest carbon content in steel is also high, reaching 2.0%~2.3%. Cold working die steel has high carbon content, and its structure mostly belongs to hypereutectoid steel or ledeburite steel. Commonly used steels include high-carbon low-alloy steel, high-carbon high-chromium steel, chromium-molybdenum steel and medium-carbon chromium-tungsten alloy steel.

Hot working dies are divided into hammer forging, die forging, extrusion and die casting, including hot forging dies, pressure forging dies, stamping dies, hot extrusion dies and metal die casting dies. Hot deformation dies not only have to bear huge mechanical stress in their work, but also bear repeated heating and cooling, resulting in great thermal stress. Hot-working die steel should not only have high hardness, strength, red hardness, wear resistance and toughness, but also have good high-temperature strength, thermal fatigue stability, thermal conductivity and corrosion resistance, and also require high hardenability to ensure the consistent mechanical properties of the whole section. For die-casting steel, the surface layer should not crack after repeated heating and cooling, and it can withstand the impact and erosion of liquid metal flow. This kind of steel generally belongs to medium carbon alloy steel, with carbon content of 0.30%~0.60%, belonging to hypoeutectoid steel. As more alloying elements (such as tungsten, molybdenum and vanadium) are added, some steels become eutectoid or hypereutectoid. Commonly used steels are chromium manganese steel, chromium nickel steel and chromium tungsten steel.

Plastic molds include thermoplastic molds and thermosetting plastic molds. Steel for plastic molds needs certain properties, such as strength, hardness, wear resistance, thermal stability and corrosion resistance. In addition, it also requires good manufacturability, such as small heat treatment, good processability, good corrosion resistance, good grinding and polishing performance, good repair welding performance, high roughness, good thermal conductivity and stable size and shape under working conditions. In general, hot-working die steel can be used for injection molding or extrusion molding; Cold working die steel can be used for thermosetting molding and dies requiring high wear resistance and high strength.
