Abstract
An injection molding machine to prevent a molded piece from being separated from a mold after molds are disassembled from each other includes a first mold, a second mold assembled with the first mold to form a cavity, and a binding device or a pressing device to get a molded piece held in the first mold when the first mold and the second mold are disassembled from each other.
Claims25
An injection molding machine, comprising:
- a first mold;
- a second mold assembled with the first mold to form a cavity;
- and
- at least one binding device to get a molded piece held in the first mold when the first mold and the second mold are disassembled from each other, the binding device including a binding member movably mounted to the first mold to bind or release the molded piece and a driving unit mounted to the first mold to move the binding member back and forth.
An injection molding machine, comprising:
- a first mold;
- a second mold assembled with the first mold to form a cavity;
- and
- at least one pressing device to press a molded piece so that the molded piece is held in the first mold when the first mold and the second mold are disassembled from each other, the pressing device including a pressing member movably mounted to the second mold to press or release the molded piece and at least one driving unit mounted to the second mold to move the pressing member back and forth.
An injection molding machine, comprising:
- a fixed mold;
- a movable mold spaced apart from the fixed mold;
- two rotatable molds movably and rotatably mounted between the fixed mold and the movable mold, the two rotatable molds being selectively assembled with the movable mold to form a first cavity and selectively assembled with the fixed mold to form a second cavity;
- and
- at least one binding device to bind a first molded piece formed in the first cavity so that when one of the two rotatable molds is disassembled from the movable mold, the first molded piece is held in one of the two rotatable molds,
- wherein the binding device includes a binding member movably mounted to the two rotatable molds to bind or release the first molded piece, and a driving unit mounted to the two rotatable molds to move the binding member back and forth.
An injection molding machine, comprising:
- a fixed mold;
- a movable mold spaced apart from the fixed mold;
- two rotatable molds movably and rotatably mounted between the fixed mold and the movable mold, the two rotatable molds being selectively assembled with the movable mold to form a first cavity and selectively assembled with the fixed mold to form a second cavity;
- and
- a pressing device to press a first molded piece formed in the first cavity so that when one of the two rotatable molds is disassembled from the movable mold, the first molded piece is held in one of the two rotatable molds,
- wherein the pressing device includes a pressing member movably mounted to the movable mold to press or release the first molded piece, and at least one driving unit mounted to the movable mold to move the pressing member back and forth.
A method of operating an injection molding machine, the method comprising:
- forming a cavity by assembling a plurality of molds with each other;
- disassembling the plurality of molds from each other;
- and
- holding a molded piece in one of the molds with a pressing device when the molds are being disassembled and a predetermined distance between the molds is not exceeded.
A method of operating an injection molding machine, the method comprising:
- forming a cavity by assembling a plurality of molds with each other;
- disassembling the plurality of molds from each other;
- and
- binding a molded piece in one of the molds with a binding device while the plurality of molds are in a state of being disassembled from each other.
