A mold conveyance guide apparatus includes: a linear guide that is attached along a conveyance direction of a mold to a mold attachment surface of at least one of a fixed platen or a movable platen to which the mold is fixed; a slider that is movably attached to the linear guide; and a coupling arm that is swingably attached to the slider in a direction coming closer to or separating from the mold attachment surface and is coupled to the mold in an engageable and disengageable manner.

An optic can manage light emitted by a light emitting diode. The optic can comprise a backside that faces the light emitting diode and a front side opposite the backside. The front side can be convex. The backside can have a central region that is adjacent the light emitting diode and that is either concave or convex. One or more grooves can extend peripherally about the central region. An injection molding system can produce optics in which the backside comprises the concave central region as well as optics in which the backside comprises the convex central region. The molding system can utilize one molding member shaped according to the front side of the optic. That molding member can be compatible with two other molding members that are shaped according to the different backsides of the optic. Thus, two different optic forms can be produced with three molding members.

A tool insert for the production of an object by an injection molding method, wherein the injection molding tool includes an insert frame and at least one lamination assembly having a plurality of individual laminations, wherein the at least one lamination assembly is inserted in the insert frame. In further aspects, the invention relates to a method and a system for producing an object having curved surfaces using the tool insert, and to an object which can be produced with the method. The system for producing an object comprises a tool insert and a sliding element. A basic idea of the invention is that curved surfaces can be introduced into the object in that the insert frame has curved surfaces and/or at least one distortion cushion is arranged between the insert frame and the at least one lamination assembly.

A method of producing an assembled product includes a first step of clamping a mold including a first unit and a second unit, a second step of forming the plurality of parts by injecting molten resin into each of a plurality of cavities, a third step of opening the mold, and a fourth step of respectively opposing the plurality of parts held by the first unit in the third step to corresponding assembling portions of the second unit. The first through fourth steps are repetitively performed, and in the first step, the plurality of parts held by the first unit are supplied to the corresponding assembling portions, and the plurality of cavities are defined by first forming portions of the first unit and second forming portions of the second unit.

A method including providing a mold cavity to produce an outer contour of an acoustic resonator and providing a mold core to produce an inner contour of the resonator. The inner contour corresponds to a plenum, and a connecting channel in fluid communication with the plenum. An insert fitting adjacent to the mold core defines a length of the connecting channel during injection molding of the resonator.

In one embodiment, a gate insert includes an injection gate body having front and rear opposite sides and an aperture extending through the injection gate body between an injection gate outlet on the front side and an opening on the rear side. The injection gate body is connectable to and disconnectable from a gate pad in a cavity plate from a front side of the gate pad and from a front side of the cavity plate. In another embodiment, a cavity flange includes a molding body defining at least a portion of a molding cavity shaped to mold a shell of a closure for a container. The molding body is connectable to and disconnectable from a gate insert in a cavity plate from a front side of the gate insert and from a front side of the cavity plate. Other apparatuses are disclosed.
