Background

With the development of mobile terminals (smart phones, tablet computers, and the like), in addition to the curved-screen smart phone released by samsung and L G, the smart phone released by apple has more non-planar glass with an arc chamfer at the edge, that is, the middle area of the glass is a plane and the edge of the glass is curved for transition.

When the curved glass is formed, high-temperature hot pressing needs to be carried out by adopting a mold, at present, a pair of molds are usually adopted in a factory to carry out hot pressing on four pieces of glass so as to improve the processing efficiency, generally, a steel plate is arranged on the upper surface of an upper mold, the upper surface of the steel plate is vertically and slidably connected with a butting column driven by a cylinder, and when the cylinder drives the butting column to slide downwards, the lower end surface of the butting column butts against the upper surface of the steel plate, so that the glass is pressed in cavities of the upper mold and the lower mold, and shaping is further realized; however, in the high-temperature hot pressing process, because the principle of expend with heat and contract with cold, the steel sheet can take place 1 silk, even 2 deformation (if the surface deformation presents unsmooth undulation), like this when the butt joint post is pushed down by the cylinder, the lower terminal surface of butt joint post and the upper surface of steel sheet realize the surface contact, just cause easily that the mould atress is inhomogeneous, lead to some products not inseparable enough in the laminating of mould, this 1 silk, even 2 errors of silk are huge to the quality influence of product, have increaseed the defective rate of product.

Content of application

To the not enough of above-mentioned prior art, the purpose of this application is to provide a universal point pressure formula shaping structure, has the advantage that improves the product yield.

The technical purpose of the application is realized by the following technical scheme: the utility model provides a universal point pressure formula shaping structure, is including the steel sheet that is used for pressing the mould and the butt post that moves along perpendicular to steel sheet surface direction, the butt post is equipped with the butt piece that realizes the point contact with steel sheet surface central point position.

Preferably, the bottom of the abutting part is arranged in a convex curved surface.

Preferably, the abutment bottom has a vertex abutting against the steel plate.

Preferably, the abutment member is slidably connected to the steel plate.

Preferably, a sliding groove is formed in the steel plate, and the outer wall of the abutting part is in sliding abutting fit with the inner wall of the sliding groove.

Preferably, the longitudinal section of butt joint piece is trapezoidal, the sliding tray is including the perpendicular section inner wall that is used for the trapezoidal section inner wall of laminating butt joint piece and is used for butt joint piece lateral wall.

Preferably, still include the frame, the frame is equipped with and supplies the gliding spout of butt post, be equipped with in the spout with the bearing of the gliding butt of butt post, the frame is equipped with the gliding driving piece of drive butt post.

Preferably, the bearing is a cross bearing.

To sum up, the beneficial effect that this application has: during high temperature hot pressing mould, even the steel sheet takes place to deform because of expend with heat and contract with cold, the butt post removes along perpendicular to steel sheet direction for the butt post realizes the point contact with steel sheet surface butt, compares among the prior art lower terminal surface of butt post and the upper surface realization surface contact of steel sheet, has reduced the lifting surface's of steel sheet surface area, and the atress concentrates on steel sheet surface central point to put, and it is more even to do benefit to the mould atress, thereby guarantees the inseparable degree of laminating of product in the mould, and then promotes the yield of product.
