Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example (b):

as shown in fig. 1 and 2, the utility model discloses a glass 3D hot bender that varies thickness, including frame 1 and the mould 3 that oven 2 and lie in oven 2 on locating frame 1, oven 2 has chamber door 21, is equipped with heat pipe 22 on the 2 inner walls of oven, and 3 one sides of mould are equipped with temperature sensor 23, and mould 3 is including the die 31 that lies in the below and the terrace die 32 that lies in the top, and terrace die 32 can go up and down for die 31, is equipped with a plurality of suction holes 311 in the die cavity of die 31, and all suction holes 311 are connected in a suction pipe 312. This equipment adopts mould 3 to make the 3D glass product that has complex structure, and the quality is guaranteed.

① feeding, placing the glass to be processed in the cavity surface of the concave die 31, closing the door 21, wherein the shape of the glass to be processed belongs to an unprocessed flat structure and needs to be shaped in the die 3.

② heating, the temperature inside the oven 2 is raised to completely melt the glass by the heat pipe 22, the hard glass is transformed into a molten state which is easy to deform by heating, the concave die 31 forms a groove body for accommodating the molten glass, the heating temperature of the heat pipe 22 is detected by the temperature sensor 23, and the actual temperature can be adjusted according to the components of the glass.

③ pressing, the male die 32 descends and the female die 31 closes the die to make the glass into the required shape, the temperature is reduced to the semi-solidification temperature of the glass after pressure maintaining, the die 3 adopts a similar die casting mode to change the glass into a cavity structure, and the glass is gradually hardened by cooling in this state.

④ the mould is opened, the semi-solidified glass is sucked in the cavity surface of the concave mould 31 by the air suction hole 311, the convex mould 32 rises and is separated from the glass, in order to avoid the glass from being completely cooled and clamped on the convex mould 32, the convex mould 32 needs to be separated when the glass is still semi-solid, the vacuum generating device connected with the air suction pipe 312 can lead the air suction hole 311 to generate negative pressure, and the glass is not taken out by the convex mould 32 and is not broken.

⑤, cooling, namely, continuously cooling the inside of the oven 2 to the discharging temperature, and taking out the solidified glass finished product from the concave die 31.

As shown in fig. 1, the rack 1 is provided with a control screen 11 for displaying conditions in the oven 2. Control panel 11 can show the temperature that temperature sensor 23 sensed, information such as clamping pressure, supplies operating personnel to judge whether normal operating condition.

As shown in fig. 1, the bottom of the frame 1 is provided with two pairs of rollers 12. The roller 12 can facilitate the electric connection between the dragging position of the hot bending machine and a power supply socket.

As shown in fig. 1 to 3, the male mold 32 is connected with a driving rod 33 penetrating through the top of the oven 2, the driving rod 33 is provided with a plurality of horizontal insections 331, a servo motor 34 is fixed above the oven 2, and a main shaft of the servo motor 34 is connected with a gear 341 engaged with the insections 331. The driving mode can more stably carry out the actions of closing and opening the mold, and avoids unqualified products caused by the splashing of the molten glass under severe collision.

As shown in fig. 2, the lower portion of drive rod 33 includes a thick rod 332 that passes directly through the top of oven 2, which has a double-layer guide structure at the top of oven 2. The thick rod 332 is used to improve the strength of the driving rod 33 in the oven 2, and the double-layer guiding structure enables the male die 32 to be matched with the female die 31 structure more accurately. Therefore, errors caused by thermal expansion of parts can be reduced, and the precision of the 3D glass product is ensured; the oven 2 of the double-layer structure is also advantageous for thermal insulation.

As shown in fig. 2, the female mold 31 is provided with a plurality of positioning posts 312 with reduced tops, and the male mold 32 is provided with positioning holes 321 matching with the positioning posts 312. When the mold is closed, the positioning post 312 penetrates into the positioning hole 321, so as to ensure the relative position of the positioning post and the positioning hole, and avoid the problem of mold collision caused by thermal deformation.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
