A supplementary part attached to the top or side of a casting to avoid defects。In the mold﹐The riser cavity is a container for storing liquid metal﹐Its functions are multifaceted。Different risers with different functions﹐Its form﹑The size and location are different﹐therefore﹐The design of the riser should consider the properties of the casting alloy and the characteristics of the casting。 For alloys with small volume shrinkage during solidification(Gray cast iron)﹐Or alloys that do not produce concentrated shrinkage holes(tinbronze)﹐The main function of the riser is to discharge the gas in the cavity and the metal liquid mixed with inclusions or oxide film at the front of the collection flow﹐To reduce defects in castings。This kind of risk
The planetary reducer is the most important type of reducer that matches the servo motor，When selecting a planetary gear reducer，First of all, determine the reducer reduction ratio，If the standard reducer does not have the reduction ratio you need，Please choose a close or customized reducer from our company。 After determining the deceleration ratio，Please multiply the rated torque of your chosen servo motor by the reduction ratio，The value obtained is in principle less than the rated output torque of the similar reducer provided in the product catalog，At the same time, the overload capacity of the driving motor and the maximum working torque required in practice should be tested。The maximum operating torque required is indicated in the rated output torque2position。Meet the above conditions
When the plastic melt enters the rapidly cooling mold cavity，The cooling rate of the product surface is much faster than that of the inner layer，The surface layer cools and solidifies rapidly，Due to the poor thermal conductivity of solidified plastics，The product solidifies very slowly inside，When the gate is closed，The central cooling shrinkage cannot be fed，In that way，The inner layer is stretched by contraction，And the surface is in the opposite state of compressive stress，This stress is not eliminated after the mold is opened and remains in the product，We call this residual stress or internal stress。There are three kinds of internal stresses in injection molded products：①Quench stress，②Frozen molecular orientation，③Volume strain hereon，We only match the mold temperature
