Description

Mold structure used to make molded glass

technical field

This work relates to a mold structure, and more particularly to a mold structure for making molded glass.

Background technique

Generally speaking, the glass material is in the shape of a flat plate. To produce a shaped glass, the known method is to arrange flat glass material between an upper mold and the lower mold, then heat the upper mold, the lower mold, and the upper mold and the lower mold. between the pieces to soften the glass material. When the above-mentioned glass material is softened, the upper mold and the lower mold can perform mold clamping action, so as to shape the shape of the glass material.

However, since the known upper mold and lower mold do not have a supporting structure, most of the glass materials will be in a suspended state during the heating process. Therefore, when the glass material is heated to soften, most of the glass material will undergo a thermal deformation due to no structural restrictions, resulting in wavy textures on the surface of most glass materials, which will affect the transparency, thereby affecting the product quality and reducing the product quality. Competitiveness in the market.

The support portion 44 is used to abut against the periphery of the support member 42 (ie, the glass plate). When the molding glass 32 is not formed, the supporting portion 44 can exert force on the second male mold part 40 to support the second male mold part 40 . Thereby, the second male mold part 40 and the first male mold part 36 clamp the molded glass 32 together, so that the molded glass 32 is in the state shown in FIG. 9 .

When the molded glass 32 is formed, the mold structure 30 can be heated by an external heat source (not shown in the figure), so that the temperature of the molded glass 32 and the supporting member 42 increases. However, in this invention, the support member 42 and the molded glass 32 can be designed to have a heat softening temperature close to that of the molded glass 32. For example, the support member 42 of the same material as the molded glass 32 can be used, so when the temperature of the molded glass 32 and the support member 42 rises to the softening temperature, The molded glass 32 and the support 42 are then softened simultaneously.

In this way, the mold structure 30 can complete the mold closing process, and then shape the molded glass 32 as shown in FIG. 3 .

It is worth mentioning that two through holes 48 are formed on the bottom surface of the cavity structure 341 (as shown in FIG. 7 ). As shown in FIG. 10 , when workers want to take out the molded glass 32 , they can use a jig 50 on which two protrusions 501 are arranged. The two through holes 48 can allow two protrusions 501 to pass through, so that the protrusions 501 can be pushed against the second side S2 of the second male mold part 40 through the through holes 48 along the second direction X2, so as to drive the first male mold Part 36 and the second male mold part 40 are separated from the clamping position as shown in FIG. 10 . In this way, the molded glass 32 can be removed from the mold structure 30 .
