A resin fan includes a semi-molded article in which a first circular plate and blades are integrated. While the semi-molded article is retained, a composite mold is moved to a secondary molding side, a second mold is put in a first position and a third mold is moved to the first position and inserted into the first mold. An intermediate part extends over the inner surface-side of a large-bend part, and causes the end of the third mold to engage with the first mold. Next, resin is poured into a secondary forming mold, and a second circular plate is integrally molded continuous with the blades of the semi-molded article, and a fan is molded. Together with the opening of the second mold and the composite mold, the third mold and the composite mold are opened, each of the molds is moved to a second position.

Injection molding utilizing targeted heating of mold cavities when in a non-molding position, thereby facilitating enhancement of the appearance and strength of injection molding parts in a manner that does not significantly increase cycle times or energy consumption.

An injection molding machine includes a machine base; a stationary platen fixed to the base for holding a stationary mold section; a moving platen slidably supported by the base for holding a moving mold section; a rotary apparatus slidably supported by the base axially intermediate the stationary and moving platens for supporting a plurality of center mold sections and moving the center mold sections among axial positions directed toward the stationary and moving mold sections and lateral positions directed toward the operator and non-operator side of the machine; and a part-handling apparatus mounted to the stationary platen. The part-handling apparatus includes an end-of-arm tooling disposed laterally outboard of the rotary apparatus. The end-of-arm tooling is movable laterally between an engaged position for interacting with molded articles in one of the center mold sections in the lateral positions, and a disengaged position spaced laterally outwardly from the engaged position.

The invention is directed to an injection molding device for manufacturing of composite products comprising a combination of a blank and an injection-molded plastic component, the product and a method of manufacturing of these composite products. The injection molding device comprising two outer mold halves displaceable along a first axis and a center block being arranged, with respect to the first direction, between the outer mold halves rotatable around a center axis perpendicular to the first direction. The center block carrying inner mold halves on at least one pair of side faces, which each form with outer mold halves in the closed position at least one cavity. The at least one cavity comprises at least one clamping means to clamp at least one blank, and in the closed position of the injection molding device forming at least one compartment to receive liquefied plastic material to form a plastic component interconnecting to the blank along at least one pair of adjacent edges.

A two-color molding die includes: a fixed primary die; a fixed secondary die; and a movable die. The fixed primary die includes a first concave portion. The movable die includes a second concave portion facing the first concave portion, and a core pin that protrudes from a base end surface of the second concave portion toward a base end surface of the first concave portion to form a tubular primary molding cavity between the core pin and the first concave portion and the second concave portion. The fixed secondary die includes a third concave portion configured to form a concave secondary molding cavity.

An injection molding apparatus includes: a first fixed mold attachment and detachment unit configured to attach and detach a first fixed mold; a second fixed mold attachment and detachment unit configured to attach and detach a second fixed mold; a first movable mold attachment and detachment unit configured to attach and detach a first movable mold; a first injection unit configured to inject a first molding material through a first gate opening of the first fixed mold; a second injection unit configured to inject a second molding material through a second gate opening of the second fixed mold; and a position changing unit configured to change a position of the first movable mold attachment and detachment unit such that the first movable mold is located at a position facing the first fixed mold or the second fixed mold. The position changing unit includes: a driving unit, a rotation shaft member configured to rotate by the driving unit, and a rotation disk coupled to the rotation shaft member and provided with the first movable mold attachment and detachment unit. The rotation disk is configured to rotate about a rotation axis of the rotation shaft member, and a flow path that communicates with the first movable mold and through which a medium flows is formed in the rotation shaft member.

The present disclosure relates to a modular mat system. More particularly, the disclosure is directed to a modular mat system with that may be built out using common pieces of mats. Specifically, a modular mat system with a mat piece with a top plate with inserts, a bottom plate with a plurality of tabs and recesses operative to engage with further mat pieces to build a mat system is discussed. The modular mat system is operative to remove water and other detritus from shoes of a user or other such platform moving across the mat system and feed it to a perimeter drain below the system.
