The specific embodiment:
Extremely shown in Figure 5 like Fig. 1; A kind of improved CD mould; Described CD mould comprises mobile side and fixation side, and described mobile side comprises that moving side group seat 1 reaches mobile side mirror face 2, and the working face of described mobile side mirror face is provided with an air-breathing annular groove 21; Said air-breathing annular groove 2 bottoms are provided with a plurality of suction hole 22; Described fixation side comprises a fixation side pedestal 3, central shaft 4, little minute surface 5, fixation side large mirror 6, die cavity ring 7 and die cavity pressure ring 8, and described central shaft 4 is arranged on the center of fixation side pedestal 3, and described central shaft is socketed with little minute surface 5, fixation side large mirror 6, die cavity ring 7 and die cavity pressure ring 8 outward successively; Described die cavity pressure ring 8 is provided with flanging convexity 81 in the junction with die cavity ring 7, correspondence is provided with a flanging groove 71 at described die cavity ring.Flanging protruding 81 cooperates with flanging groove 71, can die cavity ring 7 be pressed on the fixation side pedestal 3.Air-breathing annular groove connects negative inspiratory pressure equipment through suction hole, and stamper is sucked.Air-breathing annular groove can guarantee to suck effect, the relatively good control of molding parameter to what stamper produced annular.The consume of stamper also can reduce accordingly.Described little minute surface and fixation side large mirror are combined to form whole work minute surface, and its medium and small minute surface serves as the effect that mother cuts in this mould, cooperate with the cutting knife at mobile side center; In the CD forming process, cut out the centre bore of CD; Fixation side be provided with little minute surface reason some also be to protect fixation side large mirror 6 because cutting knife and little minute surface have wearing and tearing in punch process, if make the large mirror of a global formation; So each replacing all will be changed whole minute surface; The price of minute surface is haggled over costliness, and maintenance cost is just very high like this, and little minute surface size is only need be than the outside dimension of cutting knife big just can (cutting knife external diameter 15.06mm).
The number of described suction hole 22 is four, and described suction hole 22 internal diameters are 1.5mm, and the width of described air-breathing annular groove 21 is 3mm, and the degree of depth is 0.5mm.
Be provided with a beryllium copper gasket ring 9 between described fixation side large mirror 6 and the die cavity ring 7, the thickness of said beryllium copper gasket ring is 0.1mm～1mm.Fixation side large mirror and die cavity ring all are that die steel is made, and hardness is all bigger, directly produce friction and are easy to generate wearing and tearing, wear and tear between mutually and all compare seriously.Adopt the beryllium copper gasket ring at interval the locating effect of minute surface and die cavity ring is improved, produce disc and can not produce burr, reduce the generation of time waste product.The material of beryllium copper is softer than steel, and when minute surface and die cavity ring rubbed like this, the die cavity ring can not damage, and only needs regular replacing beryllium copper gasket ring 9, and minute surface and die cavity ring all wear and tear before need not looking like not change, and can't repair.
Also be provided with many rows' positioning ball 72 between described fixation side large mirror 6 and the die cavity ring 7.Positioning ball can improve fixation side large mirror and die cavity ring to neutrality.Two rows' positioning ball 72 preferably, is set.Make die cavity ring 7 when the CD moulding moves axially, can keep higher to neutrality.
The minute surface diameter of described little minute surface 5 is 15.1mm-30mm, is provided with water-cooled pipeline 51 in the described little minute surface.The water-cooled pipeline can reduce the temperature deviation of little minute surface and fixation side minute surface, thereby makes video disc in forming process, and cooling velocity is more even, makes the Forming Quality of the very little raising video disc of disc deflection.Water-cooled pipeline 51 needs to connect outside water-cooled recycle unit.
The minute surface diameter of described little minute surface 5 is 20mm or 26mm.
The back side of described die cavity ring is provided with a plurality of spring 73.The die cavity ring back side is provided with a plurality of springs, and a plurality of springs are used to make and move side and after the CD moulding, eject and reset.Described spring is provided with six, evenly is arranged on the die cavity ring.
Be provided with guide pin bushing 11 and guide pillar 31 more than three pairs or three pairs between described mobile side group seat 1 and the fixation side pedestal 3.Guide pillars and bushes pipe on the mold base can be strengthened the whole depth of parallelism of mould, makes mould move side and fixation side centering.Existing mould makes and relies on two cover guide pillars and bushes to make mould keeping parallelism centering; Reality in process of production because the injection machine period ratio is very fast, mould is also heavier; Produce of a specified duration; Mould can drop, and depends merely on this two covers guide pillars and bushes and can't well guarantee the parallel and centering of mould, so on mould, increase a pair or more of guide pillars and bushes again.Can better guarantee the parallel and centering of mould in process of production like this.
