Description

Technical Field

[0001] The utility model relates to the field of injection mold design, in particular to the technical field of long-distance side core pulling required for processing parts with complex shapes, and specifically is an injection mold for a solenoid valve mounting base. Background Art

[0002] The solenoid valve mounting base that needs to be processed now has a complex shape. After the injection molding is completed, a side core pulling structure is required to cooperate with the unloading.
