After confirming the number of cavities, the plastic stool molds for household use are placed in the cavity, that is, the orientation of the cavity, the placement of the cavity touches the mold scale, the planning of the pouring system, the balance of the pouring system, and the core (slider) ) Institutional planning, inserts and models
After confirming the number of cavities, the household plastic stools for daily necessities mold are placed in the cavity, that is, the orientation of the cavity, the placement of the cavity touches the mold scale, the planning of the pouring system, the balance of the pouring system, and the core (slip) (Block) organization planning, insert and core planning, heat exchange system planning, these issues are related to the selection of parting surface and gate orientation, so in the specific planning process, necessary adjustments must be made to achieve More perfect planning.
The gating system planning includes the selection of the main runner, the confirmation of the cross-sectional shape and size of the runner, the selection of the orientation of the gate, the confirmation of the gate method and the cross-section size of the gate.
