Abstract
The present invention relates specifically to moulds for cosmetic products, even more specifically to moulds for so-called “stick” products or cast products in general, to which category may belong, for example, lip glosses, lipsticks, foundations, concealers, etc. other products belonging to the same category. In particular, the present invention relates to an innovative system and method for making moulds for cosmetic products such as moulds for lipsticks, for cast products in general, moulds for compacting powders, in practice any mould for cast products in which there is a request for customization in terms of shape, logo, design and workmanship.
Claims14
A system for the realization of moulds for cosmetic products comprising at least the use of a numerically controlled milling machine with at least seven axes (A, B, X, Y, Z, C, V) of which at least the axes (A, B, X, Y, Z) are used for the realization of a mould, which includes at least one raw or semi-finished piece or a raw or semi-finished mould for cast cosmetic products (1), at least milling machines and/or other tools for mould processing characterized by the fact that at least one working tool is a diamond tip or monocrystalline diamond tip, and/or at least one working tool is a “Hammer” tool to obtain a hammer tip effect, and/or at least one working tool is a “Hydro” tool, and/or at least one work tool is a “zetina” tool, and/or at least one tool for working the piece comprises a monocrystalline diamond insert suitably shaped to work in removal, compression and polishing and said tools can be used in any combination with each other, said system being suitable for making any mould for high-precision cast cosmetic products with a surface finish.
The system for the realization of moulds for cast cosmetic products according to the preceding claims, wherein the at least one working tool for the realization of a finished mould for cast cosmetic products “Hammer” type comprises a monocrystalline diamond at the tip with a shape suitable for hammering, so it is suitable for obtaining a hammer-tip or “hammered” effect on the finished cosmetic mould.
The system for the realization of moulds for cast cosmetic products according to the preceding claims, wherein the at least one working tool for the realization of a finished mould for cast cosmetic products “Hydro” type is a cylinder comprising a monocrystalline diamond shaped in any desired shape, the Hydro tool works by removal like a milling machine or a tip like a drill and includes different profiles that allow you to create different effects on the mould to be worked according to the shape of said profiles, which can be semi-spheres with truncated cones of different diameters, to obtain a finish of the mould with a “pearl” effect “set” brilliant diamonds, or finishes such as glossy hemispheres in the mould to create a “necklace effect”.
The system for the realization of moulds for cast cosmetic products according to the preceding claims, wherein said at least one working tool for the realization of a mould for cast cosmetic products “zetina” type comprises a side facing the piece and said side is made like the section of a comb with alternating fine teeth to create a satin and brushed effect on the piece.
The system for the realization of moulds for cast cosmetic products according to the preceding claims, in which at least one working tool for making a finished mould for cast cosmetic products is any as long as it is suitable for precision machining in cosmetics and the shape of the tools above these vary allowing to obtain different finishing effects.
Process or method for the realization of moulds for cast cosmetic products as per the system according to the preceding claims, comprising at least the steps of:
- Phase 1:
- processing of a mould for cosmetic products with a lathe in the case of a round mould, or processing of a non-round mould with a CNC milling machine, or with a seven-axis milling machine;
- Phase 2:
- loading of the semi-finished product (semi-finished product) such as a mould for pre-processed, pre-polished semi-finished cosmetic product on the seven-axis milling machine, the mould is mounted on a piece-holding spindle of the axes (A, B);
- Phase 3:
- centering with feeler to give precise position to the seven-axis machine with respect to the raw mould;
- Phase 4:
- creation of a tool path, which corresponds to a customized machining of the mould that is loaded into the machine;
- Phase 5:
- activates machining in a seven-axis machine, in this case the loaded piece being a mould for cast products;
- Phase 6:
- realization of pre-finished mould in processing with milling/burin that work on up to five axes for the realization of surface finishes, in a more accurate and fully automated way;
- Phase 7.1:
- disassembly of the piece from the machine for polishing or sandblasting;
- characterized by the fact that step 7.1. can be replaced by the phase:
- Phase 7.2:
- the blank remains mounted on the machine and by means of the axes (C, V) or (A, B) on which a working tool is mounted, in combination with the movement of the other axes (X, Y, Z) o (X, Y, Z, A, B) either the polishing of the surface of the mould or of the special effects made by exporting material from the mould is carried out.
System, process or method for the realization of moulds for cast cosmetic products as per the system according to the preceding claims, in which phase 7.2 in particular is a phase 7.2.n herein it can also change the type of tool to be used in step 7.2.n and with it the shapes of the diamond cutting tools, zetina, hammer, Hydro or other tool suitable for working on moulds for cast cosmetic products processed with a 7-axis milling machine, for example.
Process or method for the realization of moulds for cast cosmetic products as per the system according to the preceding claims, in which the phases (7.2.1-7.2n) can be combined with each other in combinations of two or more processes on the same raw or semi-finished piece, to obtain moulds for cast products with processes mixed together in any way, and in any processing order.
Mould device for cast cosmetic products made as per the system referred to in the previous claims and combinations of methods referred to in the previous processes in which this mould is a male for the production of any cosmetic product as long as it is cast, comprising from one to any number of processes by means of a milling machine with at least seven axes with a finish made by means of a diamond drill, zetina, hammer, Hydro or other tool or combination of machining such tools, at least one comprising a monocrystalline diamond with any variation of external shape.
