introduction：In the mold design and forming engineering condition setting，The important thing is not only V Hold the right temperature，It has to be evenly distributed。Uneven mold temperature distribution，Can cause uneven shrinkage and internal stress，Thus, it is easy to produce deformation and warping。 The mold temperature affects the rate at which the plastic hardens in the mold cavity，Low meeting Makes filling more difficult and does not shrink properly(Or recrystallization)Immediate hardening，The molding product has more filling and thermal stress residue；Too high is prone to rough edges and requires a longer cooling time。 The following effects can be achieved by increasing the mold temperature： 1.Increase the crystallinity of the formed product and

introduction：Carbon dissolves in a lattice of iron to form a solid solution，Carbon dissolve intoα——The solid solution in iron is called ferrite，Dissolve intoγ——The solid solution in iron is called austenite。Both ferrite and austenite have good plasticity。When all the carbon in the iron-carbon alloy cannot be dissolved into ferrite or austenite，The remaining carbon will form compounds with the iron——Iron carbide(Fe3C)The crystalline structure of this compound is called cementite，It is extremely hard，Plasticity is almost zero。 1.Eutectoid steel It can be seen from the iron-carbon balance state diagram that reflects the relationship between the structure of the steel and the carbon content of the steel and the temperature of the steel，When the carbon content is exactly equal to0.

introduction：Outer spherical bearing with seat[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]The rolling sound and the control method thereof Rolling sound is the harsh metal friction sound that can occur in all occasions of cylindrical roller bearings，Most occur in grease lubricated larger types of bearings，It is more likely to occur in greases with deteriorating base oil properties，Rarely occurs when oil is lubricated。
