Description
Technical field
The present invention relates to mobile phone glass to produce and process field, and in particular, to a kind of shaping mould of tetra- side hot bending products of 3D
Tool.
Background technology
Nowadays, mobile phone glass screen develops via single plate glass to the bend glass of polymorphic type, such as 2.5D glass
Glass, 3D glass etc., these glass are to make its four sides brake forming by being heated at high temperature simple glass and exerting a force.In hot bending process
Used in mold, non-product forming surface is mostly smooth planar structure, make product include planar section and arc edge
It is whole including point to have stress.Make its hot bending since four sides of product need to apply larger pressure, and the interposition of product
It puts with little need for application pressure, therefore above-mentioned mould structure is unfavorable for the hot bending of product so that the bad defect of product
Increase, such as face pressure print, R angles coining, inverted triangle, increase the precision processing difficulty of rear process, influence the shipment standard of product.
In addition, in order to improve production efficiency and save human resources, factory is configured with automatic machinery people and is given birth to mostly
Production, and the robot manipulator structure of existing mould structure and robot mismatches so that mold is easily fallen during picking and placeing,
It influences manufacturing schedule and generates defect ware.It would therefore be desirable to operation characteristic and heat according to automatic machinery people's manipulator
The forming principle (four compression bar moldings) of curved equipment designs new mold.
Invention content
In order to overcome the above-mentioned product bad phenomenon caused by mould structure defect and be not suitable with automatic machinery life
The technical issues of production mode, present invention offer one kind is simple and practical, can improve the bad defect of product and automatic machinery people is configured
The molding die of the tetra- side hot bending products of 3D of production.
A kind of molding die of tetra- side hot bending products of 3D, the four of planar section and surrounding of the hot bending product including center
Arc side, the molding die include upper die and lower die that are setting up and down and being connected together, and the upper die and lower die are oppositely arranged
Two sides be formed product face, the two sides that are disposed opposite to each other are non-product forming surface, the upper die and lower die product into
The cavity for housing hot bending product is provided between type face, in the length side on its four side of the non-product forming surface upper edge of the upper mold
To a boss is each provided with, the boss is located at the surface on four arc sides of hot bending product, and wherein perpendicular to described
The setting of die length direction is end boss, is side boss along die length direction setting.
According to the forming principle (four compression bar moldings) of hot bending equipment, set in the corresponding position of upper mold there are four boss,
The stress of four sides of mold can be increased and reduce the pressure being subject at product center.The end boss is used to improve the R of product
Angle imprints defect, and the position and area that width is imprinted according to R angles are selected；The face pressure print that the side boss is used to improve product lacks
It falls into, the cambered surface bending position that width is then printed according to face pressure is set；And the specific thickness of each boss is according to hot bending
The Deformation calculation of machine molding compression bar at high temperature comes out.
Preferably, the thickness range of the end boss is 0.17-0.23mm, and the thickness of the side boss is 0.07-
0.13mm.It is highly preferred that the thickness of the end boss is 0.2mm, the thickness of the side boss is 0.1mm.
Preferably, the end projection width is 24-26mm, and the width of the side boss is 14-16mm.
Preferably, it is additionally provided on the vertical lateral surface of the mold and the matched location structure of manipulator.
Preferably, the location structure includes the multiple location holes being arranged in upper mold and is arranged on upper die and lower die
On multiple locating grooves, in order to which manipulator is mobile or the opening and closing mold and is not easy to shake and falls.
Preferably, the location hole and locating groove are symmetrically disposed on the two sides being oppositely arranged.
Preferably, the hot bending product is glass product.
Technical solution provided by the invention has the advantages that：
1st, the mold is simple and practical, by end boss being set to make the quadrangle of product to reach at the both ends of its length direction
The effect imprinted so as to improve R angles is overlayed, is put down by setting side boss in the two sides of its length direction with reaching mitigation product
The effect that face partial compression dynamics prints so as to improve face pressure improves the quality of production of product；
2nd, the mold realizes the opening and closing of intermode up and down by being arranged on the location hole of upper mold side, to ensure that upper mold will not
It falls, while is also firmly fixed by the position for the locating groove mold for being arranged on upper die and lower die side, not only
It ensure that stability during mold movement, it can also be used to which manipulator picks and places upper mold and product orientation, is more advantageous to automated production.
