And type core 22, the protrusion of type core 22 are formed in 21 surface of punch-pin pedestal.
As one embodiment of the utility model, in the utility model, there are two the tools of cavity plate 1, i.e., cavity plate 1 includes first
The structure of cavity plate and the second cavity plate, first cavity plate and the second cavity plate is identical；And the punch-pin 2 has one, the type of punch-pin 2
There are two core 22 also has, it is respectively formed in 21 both side surface of punch-pin pedestal, and the type core 22 of the punch-pin 2 and concave die cavity 12
Size is adapted.
In hot-forming curved glass panel, the first cavity plate and the second cavity plate are separately mounted to 2 two sides of the punch-pin position
It sets, that is to say, that be located at 2 sandwiched of punch-pin and be located between two cavity plates 1 of its two sides, and 2 liang of the punch-pin
The type core 22 of side is closely inserted in the concave die cavity 12 of the first cavity plate and the concave die cavity 12 of the second cavity plate, in glass panel heat
After the completion of molded, mold is opened, makes the type of the concave die cavity 12 of the first cavity plate and the concave die cavity 12 of the second cavity plate and punch-pin 2
The separation of 22 phase of core, obtains curved glass panel.
Referring to fig. 2, as the utility model cavity die structure, more specifically, the concave die cavity 12 of the cavity plate 1 includes limit
Slot 121 and forming tank 122, the forming tank 122 are to be recessed along 121 bottom surface of limiting slot and formed；Wherein, the limiting slot 121
It is oriented to or is limited to the type core 22 to punch-pin 2, and forming tank 122 is to place glass panel materials and parts, and the molding
Slot 122 and limiting slot 121 are located at the same central axis.
Referring to figure 1, figure 2 and figure 3, because in the utility model, punch-pin 2 and cavity plate 1 are needed to cooperate and be worked, therefore, make
It for the punch structure of the utility model, needs to be adapted with 1 structure of cavity plate, more specifically, the type of the punch-pin 1 of the utility model
Core 22 includes guide ledges 221 and formation die core 222, and the top surface of the formation die core 222 from the guide ledges 221 is upward convex
It is formed out, and the size of guide ledges 221 is adapted with 121 size of limiting slot of the cavity plate 1, the formation die core 221
Size be adapted with 122 size of forming tank of the cavity plate, be required curved to keep flat glass panel hot-forming,
122 bottom of forming tank of the cavity plate 1 is set as curved, and 222 top of formation die core of the punch-pin is also set as curved,
The curvature of the curved surface of 122 bottom of forming tank is identical as the curvature at 222 top of formation die core；In hot-forming glass surface
When sheet blanks, the guide ledges 221 of the punch-pin 2 are located in the limiting slot 121 of the cavity plate and the formation die core 222 is located at
In the forming tank 122.
Referring to figure 1, figure 2 and figure 3, when carrying out hot-forming Machining of Curved Surface to glass materials and parts, firstly, glass materials and parts are put
It is placed in cavity plate forming tank 122, completes glass and load, then punch-pin 2 and cavity plate 1 are combined, mold is heated, pass through
After the slow heating of a period of time, so that glass materials and parts is heated to glass transition temperature, make Glass Transition, makes the guiding of punch-pin 2
Boss 221 is moved along the limiting slot 121 of cavity plate 1 to 122 direction of forming tank of cavity plate 1, and makes the formation die core of punch-pin 2
222 be located at forming tank 122 in glass materials and parts generation contact and to glass materials and parts generation pressure, formation die core 222 and at
Under the common active force of type groove 122, the hot-forming curvature of glass materials and parts is identical as the curvature of formation die core 222 and forming tank 122
Curved glass panel；Then after heat preservation or cooling after a period of time, separate punch-die mutually, even if the guiding of punch-pin 2
Boss 221 is moved along the limiting slot 121 of cavity plate 1 to 122 direction of forming tank far from the cavity plate 1, the formation die core of punch-pin 2
222 are separated with the glass materials and parts being located in forming tank 122, and mold realizes die sinking, forms curved glass panel.
