Description
Technical field
The utility model is related to mobile phone glass production and processing field, in particular it relates to a kind of unilateral hot bending of hot bending product
Mould.
Background technology
Nowadays, single plate glass can not meet production requirement, for the demand of all types of bend glasses
More and more higher is measured, these glass are to be molded its side camber by being heated at high temperature simple glass and exerting a force.Due to super large chi
The glass of very little model has the characteristics of length length, thickness are big, crooked radian is high, therefore is unfavorable for carrying out hot bending processing.
Existing processing mode is directly to being pressed above and below product progress, because upper mould is to be integrally formed using two board molds
Structure, pressure may result in greatly very much product planar section produce defect, such as face pressure print, R angles impressing, inverted triangle, increase
The precision processing difficulty of rear process, influences the shipment standard of product；Pressure is too small, can cause the cambered surface part hot bending of product not
In place.Even if therefore having produced finished product, its 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.
Utility model content
In order to overcome above-mentioned integrated mould to produce the technical problem of more defect, the utility model in hot bending product

The groove matched with the projection, passes through being connected together to avoid the upper mould two when pushing for the projection 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 that the planar section for preventing product does not deform, if the weight of briquetting one kicks the beam and may result in mould one and be subjected to displacement,
And preponderance can then cause product surface mould 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 fracture, 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 gross thickness of the upper mould two and arcuate structure with the upper mould one
Together so that the upper surface of the upper mould one and upper mould two is before the non-hot bending of product in same level height.
Preferably, the thickness of the upper mould one and upper mould two is set to the bottom surface of the upper mould one and upper mould after the completion of hot pressing
Two bottom surface is in the same plane.
Preferably, the arcuate structure also includes being 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 to 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 die cavity coincide after the completion of hot bending product hot pressing.
Preferably, length of the baseplane structure in hot bending product length direction is set to after hot bending product hot bending
The difference of the arc length projected length in horizontal plane corresponding with the arc length.
The technical scheme that the utility model is provided has the advantages that：The mould is simple and practical, by upper mould
Carry out sectional design simultaneously be correspondingly arranged the briquetting of different quality each section of top so that in hot bending the planar section of product and
Pressure suffered by cambered surface part is just suitable and will not influence each other, also by setting dust cover to prevent dust from entering mould
In tool, the open defect of product is reduced；The mould avoids the production defect such as face pressure print and flexibility deficiency, it is not necessary to enter
The polishing of process after row, finished product yield is up to 95%, has saved production cost.
