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
Whole uniform stressed including point.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 pressure is applied, therefore above-mentioned mould structure is unfavorable for the hot bending of product, in addition the structure design of mold
Simple coarse so that the bad defect of product increases, such as face pressure print, R angles coining, inverted triangle, increases at the essence of rear process
Difficulty is managed, influences the shipment standard of product.
In addition, the hot bending equipment used at present is mostly the semi-automatic hot bending equipment of manual operation, this equipment capacity it is low and
Waste of manpower, thus now use full-automatic hot bending equipment instead, the station of this hot bending equipment is more and is molded using four compression bars, passes through
Full-automation produces and picks and places product, and efficiency is also raised to 4 times of original hot bending equipment.In order to coordinate the life of the hot bending equipment
Production, needs to design new molding die, to improve the quality of production of product, and meets the requirement of client.
Invention content
In order to overcome it is above-mentioned because caused by mould structure defect product it is bad and the technical issues of can not match, this
Invention provide it is a kind of it is simple and practical, the bad defect of product, tetra- sides of 3D that can be matched in full-automatic hot bending equipment can be improved
The molding die of hot bending product.
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 and stress pressing plate, and the upper die and lower die block between setting up and down and the two
Connection is closed, the two sides being oppositely arranged between the upper die and lower die are formed product face, the two sides that are disposed opposite to each other are non-product
Forming surface is provided with the cavity for housing hot bending product on the formed product face of the lower die, in the non-production of the upper mold
The groove for housing stress pressing plate is provided in product forming surface, it is shorter by two along its length on the bottom surface of the stress pressing plate
Side is symmetrical arranged there are two rectangular convex block, and the convex block is overlapped and covered with the arc side position that its homonymy is set.
For upper mold, the too thick surface that can lead to product in the position that is contacted with product generates orange peel, and too it is thin then
Face pressure print can be generated, therefore the depth of the groove can imprint situation to select according to the orange peel knead dough of product, and the stress
The thickness of pressing plate can be selected according to the height inside hot bending equipment, and the upper surface of stress pressing plate should be not less than the highest of groove
Place, otherwise influences whether application of the power to mold.
Preferably, the depth of the groove is 5-7mm, and the thickness of the stress pressing plate is more than or equal to the depth of the groove
Degree.It is highly preferred that the depth of the groove is 6mm, and the thickness of the stress pressing plate is 12mm.
By setting convex block that can improve the inverted triangle problem of product, thickness can be according to the deformation of pressing plate during high-temperature molding
Amount is calculated, and width can imprint undesirable specific location to determine according to R angles on product.
Preferably, the thickness range of the convex block is 0.17-0.23mm.
Preferably, the width range of the convex block is 14-16mm.
Preferably, the hot bending product is glass product.
Preferably, in the screens platform that is fixed on for mold in hot-bending machine of being provided at both ends with of the length direction of the upper mold
Rank, and the length direction of screens step is arranged in the width direction of hot bending product.
Technical solution provided by the invention has the advantages that：
1st, the structure of the molding die is simple and highly practical, is improved by changing mold to the forced position of product
The bad defect that product occurs in hot bending improves the quality of production of product；
2nd, according to the structure of the heating furnace chamber of full-automatic hot bending equipment, the molding die is by designing groove and screens platform
Rank integrally plays fixed function to stress pressing plate and mold, so as to ensure the precision and stability of product processing；
3rd, the structure of the molding die be more advantageous to heat conduction, so as to accelerate the heating of glass board material, cooling and most
Final shaping unit process, full-automatic hot bending is coordinated to set can produce a piece of finished product in 35 seconds, and production capacity is the 4 of existing semi-automatic hot-bending machine
Times, either quality or yield can meet the requirement of client.
