    • To provide an injection molding machine (10) capable of shortening the length of time required for hot runner pressure reduction.
      An injection molding machine (10) includes a cylinder (20) that heats a molding material, a nozzle (24) that is disposed at a front end of the cylinder (20), an injection member that injects the molding material in the cylinder (20) from the nozzle (24) toamoldunit (70), a driving unit that operates the injection member in the cylinder (20), a moving unit that allows the nozzle (24) to advance and retract to the mold unit, and a controller (60) that controls the driving unit and the moving unit, in which the controller (60) performs at least a part of a first pressure reduction process in which a hot runner is reduced in pressure by the retraction of the nozzle (24) to the mold unit (70) and at least a part of a second pressure reduction process in which the hot runner is reduced in pressure by the operation of the injection member at the same time after gate seal of the mold unit (70).
    • 提供一种能够缩短热流道减压所需时间长度的注塑机(10)。 本发明提供一种注射成型机(10),其包括:加热成型材料的缸体(20);配置在该缸体(20)的前端的喷嘴(24);将该成型材料注入缸体 20)从喷嘴(24)向压电单元(70)移动;驱动单元,其操作气缸(20)中的喷射构件;移动单元,其允许喷嘴(24)前进和退回到模具单元;以及控制器 (60),其控制所述驱动单元和所述移动单元,其中,所述控制器(60)执行第一减压过程的至少一部分,在所述第一减压过程中,通过所述喷嘴(24)的缩回使热流道降压到 所述模具单元(70)以及所述模具单元(70)的浇口密封后同时通过所述注射构件的操作使所述热流道降压的第二减压过程的至少一部分。
