Abstract

A glass forming mold includes a male mold and a positioning rod. The male mold is provided with a bearing surface on which glass can be placed, and a heated hot glass is clamped between a plurality of positioning rods. The utility model utilizes the principle of expanding with heat and shrinking with cold, which can be naturally attached to the male mold, and the required glass of different shapes can be molded naturally.

Description

A glass forming mold

technical field

The utility model relates to a forming mold, in particular to a glass forming mold.

Background technique

In the existing glass manufacturing industry, due to the high temperature of hot glass and its relatively soft characteristics, it is difficult to control its shape.

In addition, in the prior art, if you want to obtain glasses with different shapes or different curved surfaces, you need to make specific grinding tools separately, which is expensive and not easy to popularize.

Utility model content

The utility model designs a glass forming mold, which solves the problem that the shape of the glass is difficult to control under high temperature.

In order to solve the above-mentioned technical problems, the utility model adopts the following scheme:

A glass forming mold includes a male mold and positioning rods. The male mold is provided with a bearing surface on which glass can be placed, and a heated hot glass is clamped between a plurality of positioning rods.

Further, the male mold is provided with a plurality of positioning holes, and a plurality of positioning rods are installed in the plurality of positioning holes.

Further, the bearing surface of the glass is a plane or a curved surface of different shapes.

Further, there are three positioning rods, and the three positioning rods form a triangle.

Further, there are four positioning rods, and the four positioning rods form a quadrilateral.

Compared with the prior art, the glass forming mold has the following beneficial effects: the utility model clamps the hot glass for shaping by setting the positioning rod, and the forming mold can make the high-temperature glass change from an uncontrollable shape to a different shape that can be controlled as one likes. Glass products, increased the types of glass products.

Detailed ways

Below in conjunction with Fig. 1 to Fig. 3, the utility model is described further:

As shown in Figure 1, a glass forming mold includes a male mold 1 and a positioning rod 2. The male mold 1 is provided with a bearing surface on which glass can be placed, and a heated hot glass 4 is clamped between a plurality of positioning rods 2. . The male mold 1 is provided with a plurality of positioning holes 3 , and a plurality of positioning rods 2 are installed in the plurality of positioning holes 3 . The bearing surface of the glass is a flat or curved surface of different shapes. There are three positioning rods 2, and the three positioning rods 2 form a triangle. There are four positioning rods 2, and the four positioning rods 2 form a quadrilateral.

As shown in FIG. 2 , the heated glass 4 is fixed above the bearing surface of the glass through four positioning rods 2 .

As shown in Figure 3, when the temperature of the glass 4 decreases, according to the principle of thermal expansion and contraction, the glass will slowly shrink. When the four positioning rods 2 cannot clamp it, it will fall to the bearing surface of the glass. If the bearing surface of the glass is set as a different curved surface at this time, glass products of different shapes will be obtained to meet the requirements of users.
