The present invention relates to a method of injection molding comprising providing an injection molding apparatus having a first mold member (18) and at least one movable mold member (20) that can move toward and away from the first mold member to close the mold, in which there is a mold cavity (33), in at least one of the first or movable mold members injecting a polymer melt into the mold cavity while it is closed, applying ultrasonic vibrations to the mold cavity by means of an ultrasonic horn (42), characterized by positioning a carrier web (34) so that, when the mold is closed, the carrier web is between the first mold member and the moving mold member, part of the web faces the mold cavity and part of it is outside of the closed mold, and injecting polymer melt into mold cavities in both the first and movable mold members between which the carrier web is positioned.
摘要:
An injection molding apparatus includes an inlet component, a plurality of nozzles, and a plurality of hoses, each of which is not heated. The hoses are connected between outlets of the inlet component and respective molding material inlets of the nozzles for conveying molding material from the inlet component to the nozzles. Hoses may also be connected between a rail plate and the nozzles for delivering cooling fluid or actuation fluid for an actuator to and from the nozzles. The nozzles may be fastened to a mold plate of the injection molding apparatus, such as by a threaded bushing. A heated insert may at least partially define the mold cavity to heat molding material in the mold cavity.
摘要:
Disclosed, amongst other things, is a back-up device that is configured to provide a structural support, in use, between a manifold and a housing member within a melt distribution apparatus of an injection molding system. The back-up device is associated, in use, with a valve-gate apparatus within a nozzle drop. The back-up device includes a cold-side member formed from a first material and a hot-side member formed from a second material. The first material is more thermally conductive than the second material. The cold-side member is configured to be thermally connectable, in use, with the housing member and the hot-side member. The hot-side member is configured to be thermally connectable, in use, with the manifold and the cold-side member. The hot-side member is also configured to prevent the cold-side member from directly contacting the manifold.

Disclosed, amongst other things, is a first aspect of the present invention, there is provided a continuous molding machine (10) that includes a frame (14), a plurality of molding devices (16) that are mounted to the frame (14) in a circular array thereon, and a cam (31) movably linked to both the frame (14) and to the plurality of molding devices (16) for driving functions thereof including at least one of: a mold stroke function; a molded article ejection function; a melt handling function; a valve gate function; and a mold clamping function. The continuous molding machine (10) also includes a first molded article handling device (90) that is configured to handle just-molded molded articles (2) from the plurality of molding devices (16). Moreover, the continuous molding machine (10) includes a post-molding device (68), the post-molding device (68) includes a post-mold cooling table (70) that is movably linked to the frame (14) of the continuous molding machine (10), and a quantity of molded article holders (72) linked to the post-mold cooling table (70), the quantity of molded article holders (72) being configured to receive and hold the just-molded molded articles (2).
摘要:
An injection-compression molding die capable of maintaining the position of an injection-compression molded article inside a molding space (30) after the injection-compression molded article is molded. A second die (2) is provided with a compression block (12) for reducing the volume of the molding space (30) and compressing a molding resin (31) loaded therein, and an external peripheral plate (11) positioned in the external periphery of the compression block (12). The positional relationship between the compression block (12) and the external peripheral plate (11) can be varied without changing the positional relationship between the external peripheral plate (11) and an ejector pin (24) for ejecting the injection-compression molded article from the second die (2).
