Description
Technical field
The present invention relates to mobile phone glass to produce and process field, and in particular, to a kind of unilateral hot bending of hot bending product
Mold.
Background technology
Nowadays, single plate glass cannot meet production requirement, for the demand of all types of bend glasses
Measure it is higher and higher, these glass be by be heated at high temperature simple glass and exert a force make its side camber be molded.Due to super large ruler
The glass of very little model has the characteristics that length is long, thickness is big, crooked radian is high, therefore is unfavorable for carrying out hot bending processing.
Existing processing method is that directly product is carried out using two board molds to press up and down, since upper mold is to be integrally formed
Structure, pressure may result in greatly very much product planar section generate defect, such as face pressure print, R angles coining, inverted triangle, increase
The precision processing difficulty of rear process influences the shipment standard of product；Pressure is too small, can lead to the cambered surface part hot bending of product not
In place.Even if therefore having produced finished product, yield is relatively low, and average unit cost increases, and existing hot bending equipment and mold can not
Produce the unilateral curved glass finished product of the oversize met customer need.
Invention content
The technical issues of in order to which above-mentioned integrated mould is overcome to generate more defect in hot bending product, the present invention provide
It is a kind of it is simple in structure, hot bending defect, the unilateral bending mould suitable for being processed to oversize product can be reduced.
A kind of unilateral bending mould of hot bending product, the hot bending product include subject plane part and are set to it
The cambered surface part of one end, the molding die include upper die and lower die that are setting up and down and being connected together, are set in the lower die
The cavity for housing hot bending product is equipped with, the upper mold includes the upper mold one being separately set and upper mold two, one He of upper mold
Upper mold two is correspondingly arranged in the surface of hot bending product plane part and cambered surface part respectively, and in the lower surface of the upper mold two
Fixed setting is useful for the arcuate structure of compressing product brake forming, is respectively arranged in the top of the upper mold one and upper mold two
Briquetting one and briquetting two.
Preferably, dust cover is additionally provided in the outside of the mold, to prevent dust from entering in mold and cause product
Open defect.
Preferably, the vertical side of the arcuate structure is provided with convex block, is provided in the cavity lateral of the lower die
With the matched groove of the convex block, pass through being connected together to avoid the upper mold two when pushing for the convex block and groove
Horizontal displacement.
Preferably, the quality of the briquetting two is greater than the quality of briquetting one.In forming process, the work of the briquetting one
With being to prevent the planar section of product from not deforming, if the weight of briquetting one kicks the beam and may result in upper mold one and be subjected to displacement,
And preponderance can then cause product surface mold print defect occur；The effect of the briquetting two is to ensure that the cambered surface part of product
In place, therefore its weight is the weight that can bear according to unformed product to set for bending, and preponderance can cause curved
Pars convoluta position is broken, and weight kicks the beam, and is unfavorable for final molding.
Preferably, the quality of the briquetting one is 2.75-3.25kg, and the quality of the briquetting two is 3.75-4.25kg.
Preferably, the hot bending product is glass product.
Preferably, the thickness phase at the maximum gauge of the upper mold two and the overall thickness of arcuate structure with the upper mold one
Together so that the upper surface of the upper mold one and upper mold two is in same level height before the non-hot bending of product.
Preferably, the thickness of the upper mold one and upper mold two is set as the bottom surface of the upper mold one and upper mold after the completion of hot pressing
Two bottom surface is in the same plane.
Preferably, the arcuate structure, which further includes, is arranged on baseplane structure corresponding with hot bending product most end, described
Length of the baseplane structure in hot bending product length direction is set as hot bending product hot pressing foregoing description baseplane structure concora crush
On hot pressing product, and the baseplane structure and the transverse plane of the cavity coincide after the completion of hot bending product hot pressing.
Preferably, after length of the baseplane structure in hot bending product length direction is set as hot bending product hot bending
The difference of the arc length projected length in horizontal plane corresponding with the arc length.
Technical solution provided by the invention has the advantages that：The mold is simple and practical, by being carried out to upper mold
Sectional design and the briquetting that different quality is correspondingly arranged above each section so that the planar section and cambered surface of product in hot bending
Pressure suffered by part is just suitable and will not influence each other, also by setting dust cover to prevent dust from entering mold
It is interior, reduce the open defect of product；The mold avoids face pressure print and curvature deficiency etc. and produces defect, does not need to carry out
The polishing treatment of process, finished product yield are up to 95% afterwards, have saved production cost.
