An injection molding system includes an injection station, a molding device, and a plunger. The injection station includes a platform including an opening and an injector over the platform. The molding device is disposed between the platform and the injector and over the opening, wherein the molding device includes a mold cavity and a clamping unit for clamping the molding device. The plunger under the platform, wherein the plunger includes a base and a rod extendable through the opening toward the molding device and retractable toward the base. An injection molding method includes conveying a molding device to an injection station and disposing the molding device between an injector and a platform; disposing a plunger under the platform; moving the injector towards the molding device; applying a plunging force on the molding device by extending the rod through the opening; and injecting a molding material into a mold cavity.

A resin molded product (10) includes a resin molded product main body (11), and a protrusion (12) integrally formed with the resin molded product main body (11) and protruding from the resin molded product main body (11). At injection molding of the resin molded product (10), molten resin flows through a portion (C-1) corresponding to the protrusion (12) in a cavity (C) defined by a pair of molds (20, 30). A concave portion (14) is formed on a rear side of the protrusion (12), and a bulging portion (12a) having a hollow bag shape is formed on a front side of the protrusion (12).

An injection molding system includes an injection molding apparatus, an actuator that moves a mold between a first position and a second position, wherein the second position is different from the first position and injection processing is performed at the second position, a linking unit that links the actuator and the mold, wherein the improvement to the linking unit includes a rotation unit that rotates around a predetermined axis based on a change in a position of the mold along a first direction that is different from a second direction that is based on the first position and the second position.

A vertical injection molding machine includes a mold clamping device configured to clamp a mold and an injection device configured to inject an injection material. The mold clamping device includes a fixed plate, an upper movable plate that is driven up and down with respect to the fixed plate, and a turntable provided on the fixed plate and is rotatable with respect to the fixed plate. In a case the turntable is provided with a plurality of types of molds configured to mold different molded articles, when the turntable is rotated, one type of the molds is switched to a molding target mold and the other type of the molds is switched to a standby target mold, and the molding target mold is clamped by driving of the upper movable plate and is injected with the injection material.

For in mold spraying, a double-inclined mixing nozzle is connected obliquely and fixedly with a side surface of a third half-mold through a lateral sealing structure and connected with a side surface of a first half-mold in an inclined and sealing manner, side faces of a first half-mold and the third half-mold are respectively provided with installation inclined surfaces. A lateral sealing structure includes a mounting plate and a sealing member. The sealing member is sleeved on the double-inclined mixing nozzle and is in transition fit with the double-inclined mixing nozzle and the mounting plate respectively. A butt sealing groove provided on the installation inclined surface of the first half-mold and is in sealing fit with the mounting plate.

A mold latch having a latch bar and a traveler with two linear followers that can co-act with the latch bar to enable a mold plate, to which the traveler is attached, to translate together in a direction with another mold plate, to which latch bar is attached.

An assembly includes a first mold component defining a first portion of a mold cavity and a first slot. The first slot corresponds to a first portion of a retention channel. The assembly also includes a second mold component defining a second portion of the mold cavity and a second slot. The second slot corresponds to a second portion of the retention channel. The assembly also includes a connector having a cross-sectional shape corresponding to a cross-sectional shape of the retention channel. The connector has thermal expansion characteristics that are different from thermal expansion characteristics of the first and second mold components such that when the first and second mold components are in contact and the connector is inserted into the retention channel, heating the assembly causes differential thermal expansion of the connector and the mold components resulting in a clamping force between the mold components.

A mold for casting a polymeric aircraft window panel includes a first mold half having a first mold surface, and a second mold half having a second mold surface. The first mold surface and/or the second mold surface have a shape conforming to a final shape for the major surfaces of the aircraft window panel. The first mold half and/or the second mold half can be formed of rolled, hydroformed, or stamped metal.

A two-platen clamp apparatus for an injection molding machine includes a first platen having a first mold mounting surface and a second platen having a second mold mounting surface. A first rail and a second rail extend parallel to each other and to a machine axis, the first and second rails disposed at a rail elevation vertically below the machine axis. The second platen is slidably coupled to the first and second rails and translatable between mold-closed and mold-open positions. At least one force-exertion member is coupled to the second platen for clamping the first and second platens together, each clamping force exerted along an axis parallel to and offset vertically below the machine axis. At least one force-reaction member is coupled to the first and second platens for resisting separation of upper portions of the first and second mold mounting surfaces during exertion of the clamping force, each of the at least one force reaction member disposed at an elevation below the machine axis.
