Background
In the 5G era, the main trend of smart phone development is that with the progress of touch screen technology and the innovation of production process, the OLED screen will be more applied to the mobile phone due to its performance advantages. The popularization rate of the flexible curved screen mobile phone is higher and higher in the future, and therefore the demand for the glass curved screen is pulled. Meanwhile, the non-touch screen mobile phone still occupies a place in the market, and a curved glass protective screen is adopted in some high-end mobile phones to meet the requirement of high quality. In conclusion, the permeability of mobile phones adopting the glass curved screen in the mobile phone industry will be higher and higher in the future, and the window size of the glass curved screen will be gradually enlarged. The scale of the demand of the curved-surface screen of the mobile phone keeps synchronous with the market of the mobile phone and rapidly increases, and meanwhile, the market has higher and higher requirements on the curved-surface screen.
In the prior art, most of the curved surface arc edge forming processes of curved surface glass are formed by hot pressing through a mold, but the conditions such as damage or deformation to the curved surface forming are easily caused due to overlarge pressure to the curved surface in the forming process, particularly, thermal expansion deformation exists when a certain temperature is reached in the hot bending process, so that the structural design of the mold needs to be adjusted to deal with the deformation.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a curved surface glass profile forming device who lies in from the edge shaping with the shaping of normal hot bending difference, puts the shaping until product plane central point, and the advantage makes the both ends cambered surface can press and targets in place, and preferential shaping can not appear warping.
The utility model adopts the technical proposal that: the utility model provides a curved surface glass profile forming device, includes die body and lower die body, the die body is offered down and is used for the fashioned shaping chamber of curved surface glass, it is provided with the mould benevolence portion that is used for curved surface glass press fit molding to go up the die body and corresponds the shaping chamber, mould benevolence portion is provided with the concave part, mould benevolence portion is located concave part both sides and is provided with press fit molding portion.
The further improvement of the scheme is that the lower die body is arranged on two sides of the forming cavity and provided with limiting tables, and the upper die body is provided with limiting grooves corresponding to the limiting tables.
The further improvement of the scheme is that arc angles are arranged on two sides of the molding cavity and correspond to the press-fit molding part.
The further improvement of the proposal is that the groove part is an arc groove and is recessed from the press-fit molding parts at two sides to the center of the die core part.
The further improvement of the scheme is that the depth of the groove part is 0.05 mm-0.015 mm.
The utility model has the advantages that:
compare traditional curved surface glass shaping structure, the utility model discloses lie in from the edge shaping with the normal curved shaping difference of heat, until product plane central point puts the shaping, the advantage makes the both ends cambered surface can press and targets in place, and the deformation can not appear in the preferential shaping. The pressure extends towards the direction of the central plane of the glass, the first qualitative property of the cambered surface of the glass is mainly controlled, and the plane is shaped again, so that the cambered surface is not pressed in place due to the influence of the plane.
In addition, the problem of improving the upper die structure of the die is solved, the radian of curved surfaces on two sides of the die is adjusted to enable the two sides of the die to be lifted by 0.01mm, and the die is firstly pressed to the edges of the upper side and the lower side in the hot bending process to enable the edges to be firstly hot-bent and formed; and the processing of the die is not influenced, and the extruded product can meet the requirement range of the glass profile tolerance.
