An insert of a die for molding a speaker grille includes a forming member. The forming member defines a forming surface, from which a plurality of pins extend for forming apertures in a speaker grille. The forming surface defines a plurality of apertures disposed at spaced locations between the pins. The apertures are interconnected with a plurality vent channels communicating the apertures with the vent channels for venting air disposed in a die when melted polymer used to form the speaker grill is injected into the die. The forming member and the vent channels are formed as a monolithic construction.

The present disclosure relates to machines and methods for reaction injection molding. In particular, the present disclosure provides small format reaction injection molding machines having exchangeable molds and reactant material tanks, as well as molds configured for use therein and associated componentry.

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.

The invention relates to a mold for small-sized parts, comprising a casing configured to be assembled on a press platen (101, 102) the casing comprising a housing receiving an insert; the insert comprising a housing for a die comprising a molding surface (121, 122); a device for heating the die, the device comprising a rod (131, 132) made of a material susceptible to induction heating mounted in the insert (350) and having one end in contact with the die, a coil (141, 142) surrounding the rod and connected to a high-frequency current generator (151, 152) such that when the coil is electrically powered, it generates an induced current in the rod (131, 132), heating the rod by induction, the rod transmitting heat to the die, wherein an outer diameter of the rod is greater than or equal to an outer diameter of a perimeter delimiting the molding surface (121, 122).

In one or more embodiments, the present invention provides a mold and molding system using 3D-Printed mold inserts for fabricating customized grips for any handlebars, tool handles, golf clubs etc. Use of these 3D printed mold insert allows for rapid and relatively inexpensive preparation of numerous mold forms, and allows formation of shapes that are not possible using standard CNC techniques.

To achieve molding insert is properly mounted to the tooling plate of the injection molding machine, a sensor head comprising confocal sensors is used. The sensor heads are placed on the tooling plate at the respective position to determine whether the desired mold insert has been mounted to that position and whether the desired mold insert has been precisely and accurately mounted to the tooling plate.

A family of manifolds for a family of engines. A first and second engine respectively have a first and second number of cylinders. The second number is at least one and smaller than the first number. Each manifold has a plenum chamber and an inlet. The first and second manifolds respectively have the first and second number of outlets, each connected to one of a first number of runner passages. The first manifold is manufactured by inserting an outlet insert for forming at least one of the first number of outlets into a first or second mold, forming a first portion thereof using the first mold, forming a second portion thereof using the second mold, and connecting the portions. The second manifold is manufactured by forming a first portion thereof using the first mold, forming a second portion thereof using the second mold, and connecting the portions.

A method of producing an injection molding tool for molding an article includes producing a replica of the article using at least one of an additive manufacturing process, a solid freeform fabrication process, or a computer numerically controlled (CNC) process. A support block is configured to receive at least a portion of the replica and support the replica with at least one of an outer peripheral surface of the replica or an inner peripheral surface of the replica positioned at a spaced distance from a peripheral surface of the support block. The replica is supported inside the support block at the spaced distance, a ceramic resin material is introduced into the spaced distance and cured to form a ceramic shell insert, the insert is removed from the cavity, and the insert is positioned within the support block to form a part of a mold tool adapted for installation in a standard plastic injection molding machine.

A method for forming a part in an injection mold, includes: heating a molding material to a molding temperature; injecting the molding material through a gate and into a molding cavity of the injection molding apparatus of any of the preceding claims; pressing the stationary half and the moving half together to form the molding cavity between the resin mold surface and the insert molding surface; moving the movable mold insert, and thereby moving the insert molding surface and adjusting the molding cavity shape, the molding cavity depth, the molding cavity volume, or a combination comprising at least one of the foregoing along at least a portion of the molding cavity; cooling a surface of the molding cavity with the cooling system; separating the resin mold surface and the moving half mold surface; and ejecting the part from the injection molding apparatus.
