[0003] In Chinese utility model patent application number: CN202223579176.6, a quantitative injection molding mold is disclosed. The eccentric wheel is driven by a motor to rotate and press down an interception plate at a certain frequency. The interception plate is used to intercept and block the pipe mouth of the second feeding pipe, and the frequency of material falling when the second feeding pipe is feeding can be controlled. The blocking time when the second feeding pipe is blocked can be controlled by setting the frequency of the eccentric wheel driven by the motor to rotate. It is used to change the amount of material fed, facilitate the control of the amount of material required for injection molding, prevent uneven discharge from affecting the appearance of the injection molded parts, cause material waste, and ensure the qualified rate of the injection molded parts.
