The upper mold fixing plate is piled on and fixed to the upper mold plate, the upper mold fixing plate is provided with a through hole communicated with the runner, the upper mold fixing plate includes a flange extending inwardly from a side wall of the through hole, the flange abuts against the mounting part.

A method of forming a molded device, such as a stopper, requiring minimal post-molding processing includes providing a four-plate mold assembly (52) having top plate (54), a sprue/vent plate (56) including a core portion (62), a main plate (58) including a recess (66) defining a mold cavity (68) having a contoured surface (70), and a bottom plate (60), closing the mold assembly (52) such that the core portion (62) enters into the recess (66) in the main plate (58) to define a space (72) corresponding to the shape of the stopper (10, 110) to be molded. A polymeric material is introduced into the mold cavity (68) to form the stopper (10, 110). A barrier layer (14, 114) can be inserted between the main plate (58) and bottom plate and adhered to the molded device (10, 110). The plates are opened and the molded device is removed.

An injection molding system and method are disclosed. The injection molding system includes a molding device and injector. The molding device defines a mold cavity and includes an inlet portion in communication with the mold cavity. The injector includes a discharging channel. An end portion of the inlet portion and an end portion of the discharging channel have non-planar end surfaces respectively, which are engageable with each other.

An injection mold structure includes a main portion, a core plate, multiple runners, a removable metal plate, a top portion, a resin mold. The core plate is in physical communication with and located within the main portion. The removable metal plate is in physical communication with the runners and the core plate. The runners are located in between the core plate and the removable metal plate. The top portion includes a cavity to receive a carbon fiber plate.

A molding structure comprising a first mold body, a second mold body suited for combining with the first mold body, a molding core, a first heating element, and a second heating element is provided. A mold cavity is formed between the first mold body and the second mold body when the first mold body and the second mold body are joined together. The molding core is disposed in the mold cavity, wherein the molding core comprises a body, an inner surface, and an outer surface. The first heating member is disposed through the body to heat the molding core. The second heating element is movably disposed on the outer surface of the molding core to preheat the molding core.

An injection molding nozzle system for delivering molten material from a manifold to a nozzle is disclosed. The manifold and nozzle are disposed within pocket of a manifold plate. The nozzle is secured to a melt-transfer bushing disposed within the manifold via a collar. The collar is secured to the bushing such that it is centered about the axis of the outlet of the bushing. A support ring supports the nozzle within the pocket such that the nozzle is centered about the axis of the pocket. In a cold state, the outlet of the bushing and the inlet of the nozzle are misaligned. In operation, thermal expansion of the components bring the outlet of the bushing and the nozzle into alignment. The melt-transfer bushing and the connection of the nozzle to the manifold, via the releasable connection between the collar and the bushing facilitates manufacture and assembly of the system.

A method for molding a composite component, which includes step (a) of providing a forming mold and a preformed substrate, in which the forming mold includes a lower mold and an upper mold matched with each other; step (b) of disposing the preformed substrate into an accommodating space, and clamping the upper mold against the lower mold such that a mold cavity is formed between the preformed substrate and the upper mold; step (c) of injecting a polymer material into the mold cavity from a sprue of the upper mold under an injecting pressure, while pushing the preformed substrate by the polymer material which is formed by the injecting pressure, thereby forming a first deformed portion; and step (d) of further clamping the upper mold against the lower mold using a molding pressure, while pushing the polymer material and the first deformed portion, thereby obtaining a semi-finished product.

A runner system for a multi-cavity injection molding system, the runner system having runners of reduced size.
