Abstract

A mold for gold stamping including a layer (10) which bears the imprinted side being made of silicone rubber; another layer (20) being made of any suitable metal combinable to the silicone layer by hot compression. The mold is made by the steps of: (a) using a conventional mold made of copper or zinc to produce a mother mold by hot compression, the texture of said mother mold being made of a suitable amounts of a mixture of bakelite, melamine and urea; (b) filling a suitable amount of silicone rubber in a molten state into said mother mold and then allowing said silicone rubber to set or harden and dry to form a first layer (10); and (c) combining a cleaned second layer (20) of suitable thickness made of copper or zinc to said first layer (10) by hot compression. <IMAGE>

Description

MOLDS FOR GOLD STAMPING The present invention relates generally to molds for gold stamping, and more particularly, to a mold which is composed of two layers, wherein the layer which bears the imprinted side is made of silicone rubber while the other layer is made of any suitable metal such as copper or zinc.
In other words, the mold of the present invention comprises a first layer which is made of silicone rubber and a second layer which is made of any suitable metal combinable to the first layer by hot compression.
The first layer is subjected to gold stamping on an object or an article. The second layer acts as a backing layer for the first layer.- Heretofore, molds for gold stamping are composed of only one layer. The said layer is generally made of metal such as. copper or zinc. Such molds are useful for carrying out the gold stamping work on metal, wood, or the like.
Nevertheless, for gold stamping work on plastic material, molds made of copper or zinc are undesirable for the following reasons: 1. Molds made of copper or zinc, due to a lack of resiliency, cause a high degree of damage when gold stamping on plastic material.
2. Plastic material normally suffers from shrinkage and therefore the surface thereof is normally not very smooth. Upon gold stamping with molds made of copper or zinc, the letters or patterns produced are usually not flat and are sometimes not clear. Such a phenomenon becomes increasingly more serious for stamping larger surface areas.
3. Molds made of copper or zinc, being quite hard in nature, cause the plastic material to lose its original smooth surface upon gold stamping work.
4. Molds made of copper or zinc, being quite hard in nature, are not capable of performing gold stamping work on arcuate surfaces of plastic material, for example the surfaces of plastic bottles, plastic cans, cosmetic containers, or the like.
The -present invention has arisen to mitigate and/or obviate the above-mentioned drawbacks of the conventional molds.
The present invention is therefore intended to provide a mold for gold stamping which includes two layers, wherein the layer which bears the imprinted side is made of silicone rubber while the other layer is made of any suitable metal such as copper or zinc.
The present invention is further intended to provide a mold which comprises a first layer which is made of silicone rubber and a second layer which is made of any suitable metal combinable to the first layer by hot compression.
The present invention is further intended to provide a mold which is made by a method, which method comprises the steps of: a) using a conventional mold made of copper or zinc to produce a mother mo-ld by hot compression, the texture of said mother mold being-made of a suitable-amounts of a mixture of bakelite, melamine and urea; b) filling a suitable amount of silicone rubber in a molten state into said mother mold and then allowing said silicone rubber to set or harden and dry to form a first layer; and' c) combining a cleaned second layer of suitable thickness made of copper or zinc to said first layer by hot compression.
Further objects and advantages of the present invention will be apparent to those skilled in the art upon reading the detailed description provided hereinbelow with appropriate reference to the accompanying drawings.
In the drawings: FIG. 1 is a perspective view of a final product of a mold for gold stamping in accordance with the present invention; and FIG. 2 is a sectional view of the mold shown in FIG. 1.
Referring to the drawings, it can be seen that a mold constructed in accordance with the present invention comprises two layers 10 and 20. The first layer 10 which bears the imprinted side 11 is made of silicone rubber. The second layer 20 is made of any suitable metal combinable to the first layer 10 by hot compression.
As for the second layer 20, there is little restriction on the choice of metal material that can be used. The choice of metal material is based on the state of the object on which gold stamping is performed.
For the purposes of performing gold stamping on a flat plastic surface, the metal material used for the second layer 20 can be both thick and hard. This is because the second layer 20, when gold stamping on a flat surface, is not required to bend. Therefore, the pattern or character thus formed is clear and unblurred.
For the purposes of performing gold stamping on an arcuate plastic surface, the metal material is preferably a thinner and softer one than that used in flat gold stamping, for.exsmple, aluminum. This is because the second layer 20 made of such a metal material is required to bend to form the pattern or character clear and unblurred.
The first layer 10 is made of silicone rubber.
This selection is made due to the strong -Si-O-Si- bond of silicone rubber. Silicone rubber has many characteristics desirable for-producing the mold of this application. For example, it is heat resistant up to 3200C and remains its good resiliency at such a high temperature. - Also, it has good weather fastness and can resist oxidation and sunlight. Moreover, silicone rubber has excellent dielectric properties and it is also non-adhesive.
A method for producing the molds of the present invention comprises the steps of: a) using a conventional mold made of copper or zinc to produce a mother mold by hot compression, the texture of said mother mold being made of a 'suitable amounts of a mixture of bakelite, melamine and urea; b) filling a suitable amount -of silicone rubber in a molten state into said mother mold and then allowing said silicone rubber to set or harden and dry to form a first layer 10; and c) combining a cleaned second layer 20 of suitable thickness made of copper or zinc to said first layer 10 by hot~compression.
While the present invention has been explained in relation to its preferred ~embodiment, it is to be understood that-various modifications can be made without exceeding the scope of the invention. It is to be understood that the scope of the invention falls within the appended claims.
