An insert member () heated by a heating device () is conveyed, by means of a conveyance device (), into a mold (). Next, shaping is performed on the insert member () inside the mold (), with the mold () being open by a minute distance. A molding material () is injected into the mold () and pressed while closing the mold () which has been open by the minute distance to thereby mold a molded article () including the insert member ().

Molded article manufacturing method, molded article, and molded article manufacturing apparatus

A convey device, which conveys an insert member into a die, includes a holding device configured to hold the insert member in an attitude in which a major surface of the insert member is in a substantially gravitational direction; a convey mechanism configured to convey the insert member to the die, while the insert member is being held in the attitude by the holding device; and a heating device configured to heat the insert member. The insert member can be heated by the heating device before the insert member is disposed in the die.

Convey device, molded article manufacturing apparatus, and method of manufacturing molded article

A method for producing a molded productinvolves the use of an insert material. The method for producing the molded productincludes a transfer step for transferring the insert materialinto a moldusing a transfer device; a placement step for placing the insert materialin the moldby deforming the insert materialin the mold; and a molding step for injecting a molding material into the mold, thereby producing the molded producthaving the insert material

Molding apparatus, method of molding, and molded products

A molding systemfor manufacturing a molded article Q by integrally molding a sheet-shaped insert member S and a molding material R, the molding system comprising: a sheet supply partconfigured to supply the insert member S; a sheet heating partconfigured to heat the insert member S; a molding apparatusconfigured to form the molded article Q by integrally molding the insert member S and the molding material R; an ejectorincluding a delivery positionand configured to transfer the insert member S between the sheet heating partand the molding apparatusand to eject and transfer the molded article Q from the molding apparatus; and a transfer robot configured to transfer the insert member S or the molded article Q between the sheet supply partand the ejector.

Molding system and method of manufacturing molded article

A method for producing a molded productinvolves the use of a moldincluding a cavityto which a molding material is supplied and an intercepting membercapable of moving back and forth within the cavity. The method comprises an interception step for moving the intercepting memberinto the cavityand an injection step for injecting the molding material into the cavity. During the injection step, the intercepting memberis used to regulate the flow of the molding member inside the cavityat the initial stage of the injection. The intercepting member is thereafter pulled into the mold

A filling step control method of an injection molding machine for filling a molten resin into a die cavity is provided. The control method has the steps of: sampling in initiating the filling step for filling the molten resin into the die cavity by controlling an injection speed and, thereafter, by controlling a filling pressure while not exceeding a predetermined value; storing the injection speed over an entire filling process when a quality product can be stably obtained during the sampling step into a storage medium as a reference waveform; and after storing the reference waveform, molding for filling the molten resin into the die cavity by controlling the injection speed to follow the reference waveform over the entire filling step.

Filling step control method of injection molding machine

A drive unit ( ) is actuated to rotate a ball screw ( ). Then, a ball nut ( ) included in the ball screw and a cross bead ( ) advance toward a movable platen ( ) to extend a toggle link mechanism ( ) gradually. Consequently, the movable platen ( ) advances along tie bars ( ), a movable platen support member ( ) attached to the movable platen ( ) moves on a base frame ( ) and a movable mold ( ) is brought into contact with a stationary mold ( ). When the mold consisting of the movable mold ( ) and the stationary mold ( ) is thus clamped, a part of the frame provided with a recess ( ) of the movable platen support member ( ) is deformed elastically to permit the deformation of the movable platen ( ) and movable mold ( ). Thus the movable platen ( ) is not restrained from deformation, clamping force can be uniformly applied to the mold and accurate moldings can be molded.
