Moreover, the base and/or the modules are designed to be connected to each other according to a plurality of different configurations and combinations in such a way that the mould can adopt a plurality of different shapes and dimensions.

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.

A multi-part compression mold for forming a complex part having a desired fiber alignment, and methods therefor, are disclosed. The multi-part mold comprises at least three sections. Specific arrangements of fiber-bundle-based preforms are introduced to more than one of the mold sections of the multi-part mold, and subjected to compression molding. The arrangements of preforms, in conjunction with the multi-part mold, result in a complex part having fibers that substantially align with anticipated principle stress vectors that arise in the complex part, when in use.

A mold for manufacturing a turbomachine fan casing of composite material, includes a mandrel around which a fibrous preform of the fan casing is to be wound; counter-mold angular sectors assembled on the external contour of the mandrel which are intended to close the mold and to compact the fibrous preform wound on the mandrel; wherein each angular sector includes a first lateral flange positioned at the first end of the angular sectors and a second lateral flange positioned at a second end of the angular sectors, the first and second lateral flanges cooperating respectively with the second and first lateral flanges of the adjacent angular sectors. An angular sector includes a first groove formed in the first of second lateral flange, a first seal being positioned in the first groove, the first seal to be compressed between the first and second lateral flanges of two adjacent angular sectors.

A modular tooling arrangement includes a base member comprising a planar working surface, a frame circumscribing a first cavity at least partially defined by the planar working surface, and a plurality of plates configured to be received in the first cavity for forming a second cavity of a desired shape and size. The plurality of plates at least partially define the second cavity configured to receive a work piece. The plurality of plates may be replaced with plates of various sizes to vary at least one of the size and shape of the second cavity.

A manufacturing method for a fibrous composite bicycle rim , and a tool having two molding devices and one circular device. The two molding devices each have one flank contact surface. A molding device is selected and a matching auxiliary molding part is connected therewith, forming a mold surface for the rim base. A first fiber composite layer is applied to the molding device and the auxiliary molding part. The other molding device is covered with a first fiber composite layer, forming the layer of the other rim flank. A circular device is formed of annular segments has a circumferential rim well contact surface and is covered by a first fiber layer, which forms the rim well. The circular device and the molding devices are connected. The fibrous composite material is allowed to set, the annular segments and the molding devices are removed, and the rim is taken out.

A method of manufacturing a fibrous composite bicycle rim , employs a tool device having a plurality of tool components including two molding devices and one circular device. The two molding devices each have one rim flank contact surface. The circular device includes a rim well contact surface. Tool components are provided, and a first varnish coat is applied to a rim contact surface and is dried. A first fiber layer of the fibrous composite material is applied to the flank contact surface of the molding devices, forming the outer fiber layers of the pertaining rim flanks. At least one first fiber layer of the fibrous composite material is applied to the circular device which forms the rim well. The tool components of are interconnected, and the tool device is closed, is heated up, and the smooth varnish coat firmly bonds with the hardening fibrous composite material.

A mold assembly for producing a part includes a first section, a second section movably coupled to the first section, and a cavity defined by the first section and the second section, the cavity being shaped to receive a part while the first section and the second section are movably coupled to each other. The mold assembly includes a joint formed by adjacent surfaces of the first section and the second section and a seal extending along the joint.

An additive manufacturing method includes removing material from a sheet to create a plurality of individual layer segments formed, placing at least two first layer segments adjacent to each other at the same height to form a first layer having a hollow interior, the at least two first layer segments defining a first portion of an exterior of a part, and placing at least one second layer segment above the at least two first layer segments to form a second layer having a hollow interior, the at least one second layer segment defining a second portion of the exterior of the part. The method includes attaching the first layer to the second layer and removing material from the first layer and from the second layer to form the part having a continuous surface that extends along the first layer and the second layer.

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.
