Definitions

  • This invention relates to a method for manufacturing decorative articles, more particularly to a method for manufacturing decorative articles by using a silicone mold.
  • decorative articles are essentially made from plastic materials that are harmful to the environment and that are not recyclable.
  • Manufacture of the conventional decorative articles begins with preparing a plurality of copper molds, each of which def ines a desired pattern, and a molding mixture including the aforesaid plastic materials and a pigment powder or paste.
  • the molding mixture is subsequently fed into each copper mold in small amounts.
  • the copper molds are heated to cure the molding mixture therein, so as to form the decorative articles.
  • the mass-production of the conventional decorative articles involves use of many copper molds, the production cost is relatively high.
  • the molding mixture used for preparing the conventional decorative articles includes the aforesaid plastic materials, the decorative articles thus made tend to have an adverse impact upon the environment.
  • the object of the present invention is to provide a method for manufacturing a decorative article that is clear of the aforesaid drawbacks of the prior art.
  • a method for manufacturing a decorative article includes (a) preparing a metal mold defining a cavity and a pattern of separated recesses disposed within the cavity, (b) filling the cavity and the recesses in the metal mold with a silicone rubber so as to form a silicone mold that defines a pattern of protrusions corresponding respectively to the recesses, and a pattern of grooves among the protrusions, (c) filling the silicone mold with a first molding material selected from the group consisting of polyurethane resins, epoxy resins and mixtures thereof, and curing the first molding material so as to form a base that defines a pattern of decorating recesses which correspond respectively to the protrusions of the silicone mold, and (d) filling the decorating recesses in the base with a second molding material selected from the group consisting of polyurethane resins, epoxy resins and mixtures thereof, and curing the second molding material so as to form a pattern of decorative elements in the decorating recesses in the base.
  • the preferred embodiment of a method for manufacturing a decorative article according to this invention involves preparation of a metal mold 6.
  • the metal mold 6 defines a cavity and a pattern of separated recesses disposed within the cavity.
  • the metal mold 6 is a copper mold.
  • the cavity and the recesses of the metal mold 6 are filled with a silicone rubber so as to form a silicone mold 7.
  • the silicone mold 7 has a bottom plate 71, and defines a pattern of protrusions 73 that protrude from the bottom plate 71 and that correspond respectively to the recesses in the metal mold 6, and a pattern of grooves 75 among the protrusions 73 of the silicone mold 7.
  • the silicone mold 7 is filled with a first molding material that is subsequently cured so as to form a base 8 that defines a pattern of decorating recesses 81 which correspond respectively to the protrusions 73 of the silicone mold 7.
  • the first molding material is selected from the group consisting of polyurethane resins, epoxy resins and mixtures thereof.
  • the curing operation of the first molding material is preferably conducted at a temperature ranging from 110 °C to 130°C for 10 minutes to 20 minutes.
  • the decorating recesses 81 in the base 8 removed from the silicone mold 7 are subsequently filled with a second molding material.
  • the second molding material is selected from the group consisting of polyurethane resins, epoxy resins and mixtures thereof.
  • the second molding material in the decorating recesses 81 in the base 8 is cured so as to form a pattern of decorative elements 92 in the decorating recesses 81 in the base 8.
  • the decorative elements 92 and the base 8 are bonded together to form a decorative article 9.
  • the curing operation of the second molding material is preferably conducted at a temperature ranging from 90°C to 110°C for 25 minutes to 35 minutes.
  • each of the first and second molding materials further includes an additive selected from the group consisting of a pigment powder and a pigment paste in such a manner that the first molding material has a color different from that of the second molding material.
  • the decorative recesses 81 in the base 8 can be filled with a plurality of second molding materials including different pigment powders or pastes so as to form a color pattern of decorative elements 92.
  • the base 8' is shown to have a configuration different from that of the base 8 of Fig. 6.
  • the decorative article 9' that is prepared using the base 8' and that includes decorative elements 92' , is shown in Fig. 8.
  • the decorative articles 9, 9' can be mass-produced by forming a plurality of the silicone molds 7 from a single metal mold 6 so that the production cost can be reduced.
  • the first and second molding materials of this invention are recyclable and pollution-free materials, environmental concerns can be avoided.
