Please refer to FIG. 2 to FIG. 4. FIG. 2 is a schematic diagram of the mold structure according to the embodiment of the present invention, and FIGS. 3 and 4 are schematic diagrams of the glass forming equipment according to the embodiment of the present invention at different operation stages. The glass forming apparatus 30 may include a first mold structure 32, a second mold structure 34, an air extraction module 36, a heating module 38, and an actuation module 40. The first mold structure 32 is movable relative to the second mold structure 34 through the positioning unit 42, wherein the positioning unit 42 may be a guide rod, a wedge-shaped structure, a corresponding concave-convex groove structure, and the like. The first mold structure 32 includes a first mold piece 44, and the shape of the molding cavity matches the surface shape of the air-permeable component 46 of the second mold structure 34. The second mold structure 34 further includes a second mold member 47, which has a communication receiving slot 48 and a suction hole 50. The air-permeable component 46 is placed on the second mold piece 47 in an inlaying or locking manner to seal the receiving groove 48.

The air extraction module 36 is disposed outside the second mold structure 34. The extraction module 36 can exhaust the gas in the accommodation space formed by the combination of the accommodation slot 48 and the ventilation module 46 through the extraction hole 50 and the corresponding exhaust passage 381 on the heating module 38; the ventilation module 46 is used to carry the molded glass At 52 o'clock, the air extraction module 36 is started for exhausting, and the negative pressure effect can be used to stably adsorb the molded glass 52 on the ventilation component 46. As shown in FIG. 2, the second mold member 47 may further include a plurality of support bars 54 arranged in a row at the bottom of the accommodation groove 48. The gap between the support bars 54 forms an air guide groove 56, and the air guide grooves 56 communicate with each other.于 气孔 50。 In the suction hole 50. The design of the support bar 54 and the air guide groove 56 is used to assist the air-permeable component 46 to uniformly adsorb the molded glass 52, and the related structural design is not limited to the previously disclosed implementation mode, but it depends on actual needs; for example, it can also be A plurality of air guide grooves are directly excavated at the bottom of the accommodation groove 48, and the part that is not excavated between adjacent air guide grooves can be regarded as a support bar.

Generally, the air-permeable component 46 can be made of a micro-porous material, or can be processed through the pores of a gas-impermeable mold material to achieve air-permeable characteristics. The ventilation component 46 may include a flat area 461 and a curved area 462. The curved area 462 is disposed around the periphery of the flat area 461. For example, the curved region 462 may be disposed on two opposite sides of the planar region 461, or may be disposed on four sides of the planar region 461, depending on the curved design requirements of the molded glass 52. FIG. 2 only discloses that the curved area 462 is located on two opposite sides of the flat area 461. However, the shape and arrangement of each area of the air-permeable component 46 can be implemented in various ways, and its application is not limited thereto.

The planar area 461 preferably has the characteristics of a breathable material. The suction module 36 is configured to suction-mold the glass 52 through the planar area 461 of the ventilation component 46; the curved area 462 selectively has the characteristics of a breathable material. If the air-permeable component 46 is made of a microporous material, the flat area 461 and the curved area 462 usually have the characteristics of air-permeable material. The region 461 has characteristics of a breathable material. The curved area 462 is used to hot-press the molded glass 52 with the first mold part 44. The molded glass 52 will not directly contact the curved area 462 before the hot-press forming, so the curved area 462 does not have the characteristics of a breathable material and will not affect the ventilation. The assembly 46 applies an adsorption force to the molded glass 52.

The heating module 38 may include a first heating block 58 and a second heating block 60 respectively disposed on the first mold structure 32 and the second mold structure 34. The two opposing surfaces are evenly heated to soften them.

The heat generated by the first heating block 58 and the second heating block 60 It is transmitted to the molded glass 52 through the first mold structure 32 and the second mold structure 34, and the molded glass 52 will gradually soften due to high temperature. At this time, the air extraction module 36 exhausts the internal air of the accommodating groove 48, so that the flat window area (meaning the middle area) of the molded glass 52 can be adsorbed on the flat area 461 of the air-permeable component 46 to prevent the molded glass 22 from generating unexpected Sexually softened sagging or warping.

When the preheating reaches the glass molding temperature, the actuating module 40 drives the first mold structure 32 and the second mold structure 34 to move relative to each other. As shown in FIG. 4, two opposite surfaces of the molded glass 52 are respectively pressed by the first mold part. 44 and the breathable component 46, the non-planar window area of the molded glass 52 (that is, the side area other than the flat window area) can be gradually bent, and the flat window area is still attached to the flat area 461 of the breathable component 46 to maintain flatness; At this time, the air extraction module 36 preferably still maintains the exhaust function. After the hot-press forming is completed, the air extraction module 36 is closed to allow the first mold structure 32 and the second mold structure 34 to cool down and enable removal and bending. After the molded glass 52. The actuation module 40 may be a pneumatic or electric motor, which is selectively connected to at least one of the first mold structure 32 and the second mold structure 34. In this embodiment, the second mold structure 34 remains stationary, and the actuation module 40 pushes the first mold structure 32 toward the second mold structure 34 to perform mold clamping; however, the first mold structure 32 can also be maintained static. The second mold structure 34 is pushed to the first mold structure 32 by the actuation module 40, or the actuation module 40 can also drive the first mold structure 32 and the second mold structure 34 to generate a relative displacement to perform mold clamping.

In summary, in the glass forming apparatus 10 of the present invention, a breathable component 46 is disposed on a side of the second mold structure 34 facing the first mold structure 32, and the breathable component 46 is used to place the molded glass 52. Before hot pressing, the suction module 36 is activated to discharge the gas in the containing tank 48. The molding glass 52 is adsorbed on the ventilation module 46, and will not slide under the influence of external forces. Although softened in a high temperature environment, Due to the supporting and absorbing function of the air-permeable component 46, it does not sag or warp, thereby maintaining the flatness of the flat window area of the molded glass 52. The actuation module 40 drives the first mold structure 32 and the second mold structure 34 to perform mold clamping. The first mold piece 44 and the air-permeable component 46 respectively press the two opposite surfaces of the molded glass 52, and the flat window area of the molded glass 52 is pasted. The flat area 461 with the air-permeable component 46 can maintain excellent flatness. The non-planar window area of the molded glass 52 forms a curved surface according to the curved area 462 of the air-permeable component 46 to complete the hot-press forming of the molded glass 52.

Compared with the prior art, the molded glass of the traditional glass molding equipment will soften and sag when preheated. The glass molding equipment of the present invention can use the breathable component to support and attract the flat window area of the molded glass, effectively avoiding the molding. Warping and warping of glass; Molded glass of traditional glass molding equipment will shift its initial position when preheated and softened, and the glass molding equipment of the present invention can use the air extraction module to exhaust, so that the molded glass can be smoothly adsorbed on the glass. Breathable components, which can greatly improve product quality.
