When using hot die steel products, there are many requirements for product use that we must pay attention to. The key of hot die is thermal deformation production and aluminum die casting. In the middle of the work, the hot working die will suffer great harm. After the mold core touches the high-temperature metal material, the temperature of the mold itself can reach 300 ° C to 400 ° C, and some temperatures can reach 500 ° C to 700 ° C. Here, we have also introduced some related contents to you. You can have a look together!

热作模具钢的使用性能要求都有哪些?

What are the performance requirements of hot work die steel?

一、冷挤压模具

1、 Cold extrusion die

冷挤压模具的工作中标准相对性较弱，而且他们还承担缩紧力和弯折力。他们在出模期内还承担一定的拉申地应力和冲击性负载。模具与钢水中间的触碰时间更长，因而加温温度高过锤头。锻模的温度较高。

The standard relativity of cold extrusion dies is weak, and they also bear the tightening force and bending force. They also bear certain Lagrangian stress and impact load during the molding period. The contact time between the die and molten steel is longer, so the heating temperature is higher than that of the hammer head. The temperature of forging die is high.

用以模具钢的冷挤压模具的特性规定是：高耐热性，优良的热冷疲劳限度，高高温抗压强度和充足的延展性。

The characteristics of the cold extrusion die used for die steel are: high heat resistance, excellent hot and cold fatigue limit, high-temperature compressive strength and sufficient ductility.

二、热冲切模具

2、 Hot punching die

热冲压模具由修边模和冲针构成。整修模具在整修全过程中没有钻削刃，仅具有传送力的作用。无效方式是钻削刃损坏，破裂和打卷。

The hot stamping die is composed of trimming die and punching needle. The refurbishment die has no drilling edge in the whole process of refurbishment, and only has the function of transmission force. The ineffective way is that the drilling edge is damaged, broken and rolled.

热冲压模具模具对模具钢的特性规定是：高耐磨性能，高韧性和热强度;为防止破裂，应具备一定的延展性;而且应当具备优良的可工艺性能。

The characteristics of hot stamping die steel are: high wear resistance, high toughness and thermal strength; In order to prevent cracking, it should have certain ductility; And it should have excellent processability.

三、锤锻模具

3、 Hammer forging die

锤锻模承担非常大的工作压力和冲击性负载，冲击性频率很高。模芯表层被高温金属材料持续加温，可使模具温度升到300℃400℃，部分温度做到500℃600℃。

The hammer forging die bears very large working pressure and impact load, and the impact frequency is very high. The surface of the mold core is continuously heated by high-temperature metal materials, which can raise the mold temperature to 300 ℃ to 400 ℃, and some temperatures to 500 ℃ to 600 ℃.

锤锻模在模具钢上的特性规定是：高韧性和优良的延展性;优良的耐磨性能和抗热冷疲惫性;因为模具规格很大，因而应具备较高的切削性能。

The characteristics of hammer forging die on die steel are: high toughness and excellent ductility; Excellent wear resistance and heat and cold fatigue resistance; Because the die specification is very large, it should have high cutting performance.

四、铝压铸模具

4、 Aluminum die casting die

铝压铸模具的无效方式包含热疲惫裂痕，热损坏和热浸蚀。

The ineffective ways of aluminum die casting die include thermal fatigue, crack, thermal damage and thermal etching.

模具钢铝压铸模具的特性规定是：高耐温性和优良的高温物理性能;非常好的抗热冷疲惫性和高传热性;具备高切削性能。模具的强度为56-60HRC，但规定高耐磨。

The characteristics of die steel aluminum die casting die are: high temperature resistance and excellent high temperature physical properties; Very good heat and cold fatigue resistance and high heat transfer; High cutting performance. The strength of the die is 56-60hrc, but high wear resistance is specified.
