Benefits of technology

[0008]It is an object of the present invention to provide a mold for manufacturing layered composite materials and a method of manufacturing such a mold that overcomes or mitigates one or more disadvantages of known molds and methods of making them, or at least provides a useful alternative.
[0009]The invention provides the advantages of precisely locating the surfaces of adjacent mold segments so as to create a continuous molding surface from one segment to another. Moreover, the bonding area between segments is improved and the sealing of the molding surface is also improved.

Problems solved by technology

The mold manufacturing process is rather long, tedious, and expensive.
These printed molds are however limited to the size of the additive manufacturing machine used to print them.
This is a problem when the production of large composite components requires a mold exceeding the capacity of the additive manufacturing machine.

Embodiment Construction

[0053]The present invention relates to an open mold for layered composite materials and a method for manufacturing such a mold where the mold is made of segments which interlock and abut precisely with each other to generate a continuous molding surface.

[0054]FIG. 1, now referred to, shows a mold 10 and its molding surface 12. The mold 10 as shown only stretches to the limits of a part to be molded and does not include trimming extensions to the molding surface 12 which are typically added to provide a neat cutting surface. The mold 10 is of the open type and is adapted to receive a moldable material, such as reinforced layered composite materials, in order to produce components made of this moldable material. The mold 10 is made from an additive manufacturing technology, such as VAT Photopolymerization, Material Jetting, Binder Jetting, Material Extrusion (commonly known as Fuse Deposition Modelling (FDM) or 3D Printing), Powder Bed Fusion, Sheet Lamination or Directed Energy Depos...

Abstract

An open mold for producing components made of a moldable material such as layered composite materials is made from an additive manufacturing technology. The mold includes at least two compatible mold segments which precisely interlock with and abut against each other. The mold thereby made may be larger than the limited printing area of an additive manufacturing machine.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to Canadian Patent Application No. 3065462 filed Dec. 18, 2019, the disclosure of which is hereby incorporated by reference in its entirety.BACKGROUND OF THE INVENTIONField of the Invention[0002]The present invention generally relates to the field of molds for the production of molded parts which can be made of composite materials for example. More specifically, the invention relates to a mold made using an additive manufacturing technology and to a method of producing such a mold.Description of Related Art[0003]Molds used in the production of components made from composite materials using a reinforcing fabric in a matrix are typically themselves made out of composite materials. Current mold technology first requires the production of a plug, which is an intermediate component representing the surface of the composite material component that is to be ultimately molded in the mold. The plug is then polished ...
