Description

Clipping 3D board-like materials hot bending die

Technical field

The utility model is related to Architectural Equipment field, more particularly to a kind of clipping 3D board-like materials hot bending die.

Background technology

Traditional 3D glass hot-bending dies are general to use with using two kinds of design sides of common two-plate and bead push-plate type Formula.

First, common two-plate：

Refering to Fig. 1, by the ＇ of the first punch-pin 1 and ＇ of the first cavity plate 2, two parts are constituted such a 3D hot bending dies altogether, first will during shaping 2D glass (hereinafter referred to as glass) is placed in the ＇ of the first cavity plate 2 locating slot, is then covered the ＇ of the first punch-pin 1, finally be will be equipped with glass The mould of glass is put into 3D glass heats bender (hereinafter referred to as hot-bending machine), after mold temperature reaches the specified temp of setting, is given The ＇ of first punch-pin 1 applies pressure, allows the ＇ of the first punch-pin 1, the ＇ of the first cavity plate 2 to close, completes forming process.Glass in this forming process All the time one side is in contactless state, top and bottom can just fit mould completely after the completion of shaping.

The mould of common two-plate, because in forming process, glass and mould are contacted in point contact or face all the time, Due to being influenceed by lever principle in forming process, when glass both sides stress, the torsion of the center section generation of glass is most Greatly, glass is caused often separately to begin to bend from most weak middle planar portion, but we need to ensure flat in production process Absolute plane is presented in face part, only allows the flexural deformation since being met the position of layout design, i.e., this is curved local curved, should not Curved place is not curved, and traditional common two-plate mold can not effectively solve this problem, so common two-plate mold life Can often occur the uneven quality abnormal in face during production.

Meanwhile, only glass surface just can completely be fitted with mould after forming process completes two moulds closure completely, is molded During glass not with two moulds completely attach to, cause glass to a certain extent be in free state, when glass is in high temperature After lower softening, in the presence of the ＇ pressure of the first punch-pin 1, glass is possible to that the phenomenon horizontally slipped can be produced, and this phenomenon can be made The large and small side of glass is abnormal after into shaping, that is, height the same side in script both sides can become high on one side after being molded, short on one side.

2nd, bead push-plate type：

Refering to Fig. 2, by the ＇ of the second punch-pin 3, the ＇ of the second cavity plate 4, the ＇ of push pedal 5, totally three parts are constituted such a 3D hot bending dies.Refer to Fig. 3 and Fig. 4, specified location during shaping first in the ＇ of the second cavity plate 4 is put into a number of ＇ of bead 6, then puts the ＇ of push pedal 5 In the ＇ of the second cavity plate 4 groove, it is covered in above the ＇ of bead 6, then glass is placed on to the ＇ of the second cavity plate 4 glass locating slot It is interior, cover the ＇ of the second punch-pin 3.The mould that finally will be equipped with glass is put into specific machine, treats that mold temperature reaches the spy of setting After constant temperature degree, pressure is applied to the ＇ of the second punch-pin 3, allows two moulds to close, completes forming process.In this forming process, the ＇ of bead 6 Glass softening transform together can be followed, under the ＇ of bead 6 support, the planar section of glass is convex with the ＇ of push pedal 5 and second all the time The ＇ of mould 3 keeps contact.

Compared to common two-plate mold, bead push-plate type mould is pushed away due to having used in the ＇ of bead 6, forming process The ＇ of plate 5 and the ＇ of the second punch-pin 3 can remain the contact with glass, therefore slow down the face occurred after shaping to a certain extent not The quality abnormals such as flat or large and small side.But it is due to that softening transform will also occur for the ＇ of bead 6 in forming process, so also needing Specifically to soften parameter, that is to say, that the softening parameter (temperature and pressure) of glass should be considered in forming process, also Consider the softening parameter than the ＇ of bead 6.Virtually increase manufacturing variables, add production difficulty, simultaneously because mould is every Complete once production and be accomplished by changing the ＇ of bead 6 to change quantity every time at four to six, and the ＇ of bead 6 can only disposably make With, add production old while be also unfavorable for volume production or automated production.

In summary, each there is larger technological deficiency in above two 3D glass hot-bending dies, therefore, existing skill The 3D glass hot-bending dies that a kind of product with stable quality, production difficulty are low, with low cost are needed in art.
