The specific embodiment
In order to describe structure of the present invention and characteristics place in detail, lift following preferred embodiment now and cooperate graphic explanation as back:
A) prepare a mould 10.
See also shown in Figure 1ly, this mould 10 has a counterdie 12 and a patrix 14, and this counterdie 12 has cave 16 in the multilayer film, and cave 16 has Fig. 1 case layer 18, one second patterned layer 20 and a basalis 22 from the bottom to top in this mould.The periphery in this counterdie 12 cave 16 in this multilayer film has a blade 24, and this patrix 14 also has a blade 26, corresponding to the blade 24 of this counterdie 12.
B) in the mould of this mould 10, insert pattern material and base material in the cave 16, and make its preliminarily forming.This step includes follow procedure:
I, the auto-vulcanization silicon rubber 28 (room temperaturevulcanization (RTV) silicon rubber) (Fig. 1 case material) of liquid state is injected Fig. 1 case layer 18 of this mould 10.
See also shown in Figure 2ly, this step is to utilize trace to penetrate the case layer 18 that (micro injection) and automation control are injected the RTV silicon rubber 28 of predetermined close on these moulds 10.RTV silicon rubber 28 can have different colors, injects the presumptive area of Fig. 1 case layer 18 of this mould 10 according to design.
II, heating RTV silicon rubber 28 make its preliminary sulfuration typing.
This counterdie 12 sent in the oven (not shown) heat, between 120 ℃ to 180 ℃, the time made the 24 sulfuration typings of RTV silicon rubber to the temperature of heating between 15 seconds to 25 seconds greatly.
III, cooling RTV silicon rubber 28.
After heating finishes, this counterdie 12 is placed on the cooling device (not shown), has the cooling fluid (be generally water) of temperature between 5 ℃ to 20 ℃ to circulate at this cooling device, by so that RTV silicon rubber 28 is cooled to room temperature.
IV, liquid RTV silicon rubber 30 (second pattern material) is injected second patterned layer 20 of this mould 10, and heat in regular turn, step such as cooling, as shown in Figure 3.
V, see also shown in Figure 4ly, have the high-temperature silicon disulfide rubber 32 approaching (hight emperaturevulcanization (HTV) silicon rubber) (base material) with one and insert in this basalis 22 with basalis 22 sizes, the shape of this mould 10.
C) see also shown in Figure 5ly, (adhesive sheet) is positioned on this HTV silicon rubber 32 with a glued membrane 34.This glued membrane 34 is a solid state heat melten gel (hot-melt adhesive orthermosensitive adhesive) or the formed bar-shape film of pressure-sensitive melten gel (pressure sensitiveadhesive), and its width and length are all greater than cave 16 in the mould of this counterdie 12.See also shown in Figure 6ly, cover this patrix 14, this blade 26 can abut in the blade 24 of this counterdie 12 and move along the blade 24 of this counterdie 12, by so that this glued membrane 34 is cut off.At this moment, can keep a shape in the mould 10 and be close in glue-line 34a this HTV silicon rubber 32 is identical with this, and this glue-line 34a is subjected to the compressing of this patrix 14 and fits tightly on this HTV silicon rubber 32 with big or small.
Certainly, also can in advance this glued membrane be cut into suitable shape and size, be positioned over again on this HTV silicon rubber 32.But the disclosed mode of embodiment more meets mass-produced needs.
D) then this mould 10 is sent in the chamber 36, seen also shown in the 7th figure, carry out the hot moulding program.At this moment, this two RTV silicon rubber 28,30, this HTV silicon rubber 32 and this glue-line 34 can be combined into one.
E) last, open this mould 10, can obtain a silicone rubber products 38.See also Fig. 8 and Fig. 9, this silicon rubber finished product 38 has a basalis 40, and it is formed by this HTV silicon rubber 32, the front of this basalis 40 has one or two layers patterned layer 42, and it is by 28,30 formation of this two RTV silicon rubber, the back side has a gum layer 44, and it is formed by this glued membrane 34.
According to the made silicone rubber products of manufacture method provided by the present invention, its basalis 40, this patterned layer 42 are to be shaped in same program with this gum layer 44.Can simplify processing procedure and reduce cost.This silicon rubber finished product 38 can melt by made this glue-line 44 by pressurization, heating, and is attached on the made object of cloth sheet, leather, silicon rubber, metal, glass or other material.
