Abstract

An ornament, sole or eraser is made by pressing a quantity of moulding material by hand into a mould cavity, heating the material in the mould to cause it to harden, cooling, demoulding and snagging to remove extraneous material. A mould manufactured from heat-resisting plastic material and which can be used in the method is also described.

Description

J 2336800 A MOULDING METHOD AND A MOULD The present invention relates to a
method of producing an ornament, a sole of a shoe, a rubber eraser or the like, and a shaping mould for use in the method. More particularly, the invention relates to a method and mould for producing ornaments (such as, for example, hair clips, brooches, tie pins etc.), soles, rubber erasers or the like from the same material.
The costs involved in conventional methods for producing such ornaments, soles, and rubber erasers from plastic material or the like, are generally quite high due to the expensive steel mould sets required and the high cost of shaping machines and professional technicians.
An object of the present invention is to provide an improved method of producing ornaments, soles, rubber erasers or the like and to provide an improved shaping mould for use therein.
According to one aspect of the present invention, there is provided a method of producing an ornament, sole, rubber eraser, or the like, the method comprising the steps of.
pressing a moulding material into the mould cavity of a shaping mould by hand to assume the shape of said shaping mould; 2 solidifying the material by heating a plurality of said shaping moulds mi a heating facility at approximately 1OWC for 3-5 minutes and taking said moulds out of the heating facility for cooling off, removing the now solid body from the shaping mould and snagging the unfinished body to form a finished product.
The method of the invention therefore includes the steps of taking a certain amount of material and pressing the material within the mould and then heating the whole mould with the material for formalising, and fmally releasing off the mould and trimming away flash and tidying the solid body to a finished product. No professional technician is needed to operate the production in these processes.
According to another aspect of the present invention, there is provided a shaping mould for use in a method of producing an ornament, sole rubber eraser, or the like, the mould being formed from heat-resisting plastic material.
The shaping mould of this invention is thus formed from engineering plastic material so that a plurality of shaping moulds can be made out from only one steel mother die set therefore decreasing the cost for moulding.
The preferred material used in this invention is a compound containing Silicone rubber, Silica, Silicone oil, Curing agent, and Pigment, and is soft to allow hand fetching, mating with the mould cavity and pressing evenly into the mould. The whole shaping mould is heated by a heating facility to solidify the material, after which it is allowed to cool and is released from the mould. The solid body is then snagged to a finished product.
3 The shaping mould of this invention refers to an integral mould with a cavity and holder part die cut from heat-resisting plastic material.
The present invention will now be described with reference to the accompanying drawings, in which:
FIGURE 1 is a block chart of an embodiment of the producing method of the present invention; FIGURE 2 3 are views of the structure of the shaping mould of an embodiment of the present invention; FIGURE 4 is a view showing the shaping mould with material stufled into.
FIGURE 5 is a view of the fmished product of a sole produced by the process of the present invention; FIGURE 6, 7, and 8 are views of the finished product of ornaments produced by the process of preferred embodiment of the present invention.
Referring to Figure 1, the material (1) in the present invention is a compound containing Silicone rubber 34 %-35 %, Silica 42 I/o-43 %, Silicone oil 20 0/G-22 %, Curing agent 1.2 %-1.5 %, and Pigment 1.2 I/o-1. 5 % This material is soft, having a consistency generally similar to that of clay. A certain amount of the material may thus be fetched or taken and mated with each mould cavity by pressing it evenly into the mould cavity by hand to formalise (2) the material. Several moulds are prepared with material (1) in this way.
1 4 The prepared moulds with formalised material are then heated together by a heating facility for heating solidification (3). The heating facility may be a heating pot with water boiled away at 100 OC for 3-5 minutes, or an oven.
After solidification (3) by heating, the moulds and material (1) are allowed to cool, after which the solidified material is released (4) from the moulds. The solid body thus obtained is then snagged, (5) trimming away any unwanted flash to accomplish a finished product (6). The finished product is optionally formed as ornaments, soles, or rubber erasers (as shown in Figures 5 to 8).
Referring now to Figures 2, 3, the shaping mould (7) of the present invention is an integral mould with a mould cavity area (8) and holder (9) formed by, for example, moulding or die cutting from heat-resisting plastic material. It is thus possible to make a plurality of shaping moulds (7) from only one steel mother die set. One or more than one mould cavities (10) could be arranged in said mould cavity area (8).
In the preferred embodiment of the present invention, one and two mould cavities (10) are formed by adding 25 % of glass wool into polypropylene through granular mixing process and die cut at 200'C-22WC. The shape of said mould cavity (10) is optionally formed as ornaments (such as ornaments on hair clip, brooch, tie-pin), sole, rubber eraser and so on.
