A method for verifying whether a molding insert (1a, 1b) is accurately mounted to a tooling plate (2a, 2b) comprises the steps of: a) providing a confocal sensor (3a, 3b); b) arranging the confocal sensor (3a, 3b) such that a confocal sensor reference plane (32a, 32b) as well as a tooling plate reference plane (22a, 22b) are normal to a mounting axis (21a, 21b) of the tooling plate and spaced from each other by a predetermined first distance (d1, e1); c) measuring a second distance (d2, e2) between the confocal sensor reference plane (32a, 32b) and a central impingement location (11a, 11b) on a molding surface (12a, 12b) of the molding insert (1a, 1b); d) based on the measured second distance (d2, e2) as well as based on the predetermined first distance (d1, e1), determining a third distance (d3, e3) of the central impingement location (11a, 11b) relative to the tooling plate reference plane (22a, 22b); e) comparing the third distance (d3, e3) with a predetermined target distance, and f) determining that the molding insert (1a, 1b) is accurately mounted to the tooling plate (2a, 2b) if the difference between the third distance (d3, e3) and the predetermined target distance is less than a threshold difference.

A mold insert has at least one filament cavity and a stack of at least a first and second insert plates, wherein the first plate has a front face that closely abuts a front face of the second insert plate. A portion of the a filament cavity is provided in at least one of the front faces of the first and second insert plates such that the filament cavity is open at a top surface of the mold insert but does not extend to a bottom surface of the mold insert. A venting cavity is provided in the same front face of the insert plate in which the portion of the at least one filament cavity is provided. The venting cavity, which is in air-conducting connection with the blind-hole end of the filament cavity, has a depth between 1 μm and 20 μm. A method of manufacturing the mold insert includes providing first and second insert plates, forming a portion of a filament cavity into at least one of the front faces of the insert plates, forming a venting cavity into the front face with the filament cavity, and bringing the front faces of the plates into close abutment to form a filament cavity.

A cassette type mold apparatus includes a sub-runner formed on a parting surface of a fixed side matrix or a movable side matrix, a gate provided in a fixed side cassette mold or a movable side cassette mold and configured to inject a molten resin into a cavity space from the sub-runner, and a hot runner provided on the fixed side matrix so that a tip end thereof is aligned with the sub-runner to be perpendicular to the sub-runner and is in parallel with a mold opening and closing direction. In the cassette type mold apparatus, the movable side cassette mold can be stacked on the fixed side cassette mold in a state in which a cavity and a core are aligned and can be integrally loaded in a direction of a side surface of the entire mold.

The injection mold has a mold core including a first part and a second part. The parts are mobile relative to one another between a first injection position in which they are moved together to form an injection cavity permitting the injection of a material to form an injected part (50; 50′), and a second demolding position in which they are moved away from one another to permit the demolding of the injected part (50; 50′). The injection mold has at least one ejector designed to contribute to the demolding, and at least one movable intermediate plate (10; 10′, 20′), separate from the two parts of the mold core. The intermediate pate is arranged between the two parts of the mold core, and has at least one cutout (12; 12′, 22′) forming at least one part of the injection cavity of the injection mold.

Provided is a method for manufacturing a mold used in an injection molding device. The manufacturing method includes: a first step of shaping a stacked body as a part of the mold by discharging a shaping material to stack layers on a base plate; and a second step of manufacturing the mold including a mold base, the base plate, and the stacked body by incorporating the base plate on which the stacked body is shaped inside an opening provided in the mold base.

An injection mold, in particular for encapsulating rotors of electric machines, has a mold, wherein the mold has an arrangement of mold segments. The arrangement forms, along a longitudinal axis, a cavity for a component to be arranged. An exchange unit is provided, which is designed to remove at least one mold segment from and/or insert at least one mold segment into the arrangement, with the result that a size of the cavity can be changed.
