As a kind of optimal way, punch is provided with through hole.
Compared with prior art, the beneficial effects of the utility model: the utility model rubber seal convex-concave plate mould possesses following advantage:
1. rubber size can directly be put into the groove of mould, puts glue quick and easy, is not subject to the restriction of shape of product, can avoid product generation starved phenomenon;
2. fast owing to putting glue, the needed time of product one step cure is short, and efficiency is high;
3. mould is convenient to exhaust, is difficult for producing bubble and sulphur trace, saves rubber weight;
4. between punch and die, have gap, can make the product of compacting closely knit, unnecessary rubber is convenient to discharge;
5. it is thinner that the product of producing gained by this punch-die flies skin, flies skin and be convenient to tear;
6. the die cavity both sides of punch and the die glue groove of having a surplus; Remaining glue groove is the remaining glue groove of V-type, and mould is boundless mould, and product overlap tears, and need not rebuild products obtained therefrom appearance looks elegant again.

Embodiment 1:
In the present embodiment, the width L of described punch
1=8mm, the width L of die
2=8.5mm; The depth H of described punch
1=6mm, the depth H of described die
2=5mm.Described remaining glue groove is " V " shape, and the width of this remaining Jiao Caokaikouchu is 1.5mm, and the degree of depth is 0.9mm; Stating remaining glue slot pitch is d from the distance between punch die cavity or concave die cavity
1, described d
1=0.1mm.
Strip sizing material is put into the groove that die is 8.5mm, and the projection that punch is 8mm is put into this die groove, oppresses sizing material enter in the die cavity of mould by punch, between punch and die, possesses L
2-l
1gap, there is the gap of 0.5mm, unnecessary sizing material is overflowed along gap, the gas of generation also overflows from gap; Gained rubber product to fly skin thinner, fly skin and be convenient to tear.In addition, because the punch degree of depth is 6mm, die depth is 5mm; Punch and die have the gap of 1mm, are provided with through hole on punch, and the gas in mould just can be discharged mold cavity by this through hole, thereby ensure that product can not produce the defect of bubble.
Sizing material in die cavity is under the effect of time, temperature and pressure, hot-forming; By controlling the temperature of upper temperature of heating plate lower than lower heating plate, product is sticked at above the punch of punch, punch is with turnover panel oriented manipulation person, and convenient operation person takes off product.
The product list chamber glue 18g making according to existing mold; The product of making according to the present embodiment mould therefor glue 14g, saves sizing material 4g; The one step cure time, by 300 seconds, drops to 180 seconds.
This rubber seal plate mould structure parameter designing is reasonable, is applicable to the rubber seal that product cross section width is less than 4mm, and mould therefor changes the semi-enclosed mould that tamps into by the open mould that tamps; Significantly improve the qualification rate of finished product, avoid the defects such as product local ageing, starved, fracture, reduced production cost.
