In the forming of compression moulding or the injection of the products such as ceramics；Mould has specific profile or cavity shape, using with cutting edge
Contour shape can make blank by profile wire shaped occur separation (punching)；It can obtain blank using cavity shape corresponding
Three-dimensional shape；Mould generally comprises two parts of dynamic model and cover half (or punch-pin and cavity plate), the two is partable；Taken out when separating
Product, makes blank injection mold cavity shaping when closing up；Mould is precision instrument, complex-shaped, bears the expansive force of blank, to knot
Structure intensity, rigidity, case hardness, surface roughness and machining accuracy all have higher requirements, and the development level of mould production is machine
The one of the important signs that of tool manufacture level.
Bend glass is the design mainstream of current intelligent electronic product, since the design of its curve meets ergonomics original
Reason, so being used in for example extensively：On the 3C Product of mobile phone, tablet PC, intelligent object wearing device etc..In order in original
Process bending section on the glass of this tablet, existing curve glass forming apparatus generally comprise one have heating chamber plus
Heat container, and one be installed on the indoor molding die of the heating.The molding die includes a die holder, and an installation
Mode in the die holder, the mode have the curved forming surface that the curvature of a radian and the glass coordinates；But now
Curve mold processing mold general structure it is more complicated, and heat it is inconvenient.
The content of the invention
