There is provided a member of a mold stack (100, 800), the member comprising: a member body (102, 802) defining a member molding surface for defining, in use, a portion of a molding cavity for molding a molded article, a member cooling circuit (120, 820) having a plurality of member cooling channels (128, 829), the plurality of member cooling channels (128, 829) being coupled in parallel to a source of cooling fluid, the member cooling circuit (120, 820) being fully encapsulated within the member body (102, 802).

A molding system is provided, which includes at least one mold part and a heating and cooling module. The at least one mold part defines a mold cavity having an opening. The heating and cooling module is inserted into the opening to close the mold cavity. The heating and cooling module includes a die insert defining a mold surface, a layered heater for heating the mold surface, and a cooling unit for cooling the mold surface. The layered heater is disposed between the die insert and the cooling unit and includes functional layers formed directly on a surface of the cooling unit or a surface of the die insert opposite to the mold surface by using layered or layering processes selected from a group consisting of thick film, thin film, thermal spray and sol-gel processes.

An injection mold assembly for injection molding an object includes a first mold tool having a first tool surface and a second mold tool having a second tool surface. The first and the second tool surfaces are cooperatively configured to define a mold cavity between the tool surfaces for an injection molding of an object. The first mold tool has a tool element with a first side that has the first tool surface, and with a second side opposite the first side. Multiple fins extend from the second side of the tool element. A base supports the fins. The tool element, the fins and the base define a coolant flow cavity at the second side of the tool element. A method of designing the mold assembly is also disclosed.

An object of the present application is to allow a first cavity mold and a second cavity mold to become integrated with each other in a state in which the first cavity mold constituting an injection cavity mold is inserted into an insertion hole of the second cavity mold, with a cooling flow path for supplying a cooling medium formed between the first cavity mold and the second cavity mold.

A thermal management system that provides metal mold surface temperature control using cyclic process thermodynamics to enhance plastic material flow and curing conditions making it possible to produce resin rich molded plastic surfaces without micro cracks or fissures to which contaminant particles can adhere or to which dirt can attach.

The device for demoulding negatives in thermoplastic injection moulds comprises an ejector (1) provided on one of the ends thereof with a figure insert (2) with a profile complementary to the part that is to be moulded, wherein said ejector (1) comprises an outer tube (11) housing an inner cooling tube (12), which cools said figure insert (2). It allows for a device to be provided for demoulding negatives in thermoplastic injection moulds which enables the part to be obtained to be cooled, the cooling circuit reaching the figure area of the mould.

In order to increase the degree of automation, an overmolding device for processing profiles, having a turntable with a worktable device that is movable in rotation about an axis of rotation in a rotation plane and has at least two processing areas, is proposed, wherein the processing areas each comprise a central plate, wherein the central plate is attached to and/or mounted on the worktable via a central-plate receptacle, wherein the turntable comprises an upper and a lower mold, which are decoupled from the rotation of the worktable device and which are arranged opposite one another with regard to the rotation plane, and wherein the upper and lower mold are movable such that, together with the central plate, they form a mold receiving the profile, and the central-plate receptacle (5) forms the fixed closing side and the upper and lower molds form the movable closing side.

A mold includes: a first molding surface configured to form a lens surface of a scanning lens being elongated in a main-scanning direction; and a first coolant passage, which is disposed within the mold and through which a coolant to control the temperature of the first molding surface flows, wherein the first coolant passage includes: a first passage portion corresponding to a first lens portion which is a portion protruding most in an optical axis direction in the lens surface; and a second passage portion corresponding to a second lens portion which is a portion retreated most in the optical axis direction in the lens surface, and the second passage portion is located to be closer to the second lens portion than a virtual plane, which passes through the first passage portion and is orthogonal to the optical axis direction.

This disclosure includes injection molds for reducing cycle times and related methods. Some molds include first and second mold portions movable relative to one another from an open position to a closed position in which each of one or more recesses of the first mold portion cooperates with a respective one of one or more recesses of the second mold portion to define a chamber. Each of the chamber(s) includes a first cooling body coupled to the first mold portion, a second cooling body coupled to the second mold portion, and first and second inserts removably coupled, respectively, to the first and second cooling bodies such that the inserts cooperate to define a mold cavity within the chamber that is configured to receive a thermoplastic material. Each of the cooling bodies has an inlet, an outlet, and a fluid cavity in fluid communication with the inlet and the outlet.

An injection molding apparatus includes: a first mounting block configured such that a fixed mold is able to be mounted thereon; a second mounting block configured such that a movable mold facing the fixed mold is able to be mounted thereon, provided with a first through hole through which a first diver is inserted, and configured to move back and forth with respect to the first mounting block along the first diver; and an injection unit configured to inject a molten material into a cavity defined by the fixed mold and the movable mold. In a state where the movable mold is mounted on the second mounting block, the second mounting block includes, between the movable mold and the first through hole, a heat conduction prevention portion configured to prevent conduction of heat from the movable mold.
