    • PURPOSE: A control method and apparatus for injection molding are provided to prevent the generation of peak pressure during injection by charging a molding material using the internal energy of the molding material. CONSTITUTION: A control method for injection molding comprises the steps of: filling molten resin in a mold under speed control until the charging pressure of the molten resin reaches a first set pressure(S1), filling the molten resin by converting the speed control to pressure control based on the first set pressure when the detected charging pressure exceeds the first set pressure(S3,S4), and converting the pressure control to pressure holding control when the charging speed becomes under the predetermined speed at the state where the molten resin is filled under the pressure control(S6,S7).
    • 目的:提供一种用于注射成型的控制方法和装置,以通过使用成型材料的内部能量对成型材料充电来防止在注射期间产生峰值压力。 构成:注射成型的控制方法包括以下步骤:在速度控制下将熔融树脂填充到模具中直到熔融树脂的填充压力达到第一设定压力(S1),通过将速度控制转换为压力来填充熔融树脂 当检测到的充电压力超过第一设定压力时,基于第一设定压力进行控制(S3,S4),并且在填充熔融树脂的状态下,当充电速度变为预定速度时将压力控制转换为压力保持控制 在压力控制下(S6,S7)。
