Description

Technical Field

[0001] This utility model belongs to the field of mold technology and relates to a mold for processing Braille glass. Background Technology

[0002] To facilitate use by the blind, existing glass products are equipped with Braille. Braille consists of many raised dots, so specific molds are needed to produce glass with Braille for use by the blind on mobile phone screens.

[0003] For example, Chinese patent application [Authorization Announcement No.: CN201573360U] discloses a Braille embossing mold, which includes an embossing female mold that is horizontally mounted on the die-cutting machine's mounting frame by bolts, an embossing male mold located directly above the embossing female mold and attached to the steel base plate of the die-cutting machine, and an elastic pad installed between the embossing female mold and the mounting frame. The embossing female mold and the elastic pad have corresponding bolt holes for the bolts to pass through. The upper surface of the embossing female mold is provided with multiple concave dots, and the lower surface of the embossing male mold is provided with multiple convex dots. The positions of the multiple concave dots and the multiple convex dots are aligned and matched to form a processing mold for processing Braille dots on cardboard packaging. The arrangement structure of the multiple concave dots and the multiple convex dots is the same as the structure of the Braille patterns and letters to be processed, and the structures of the concave dots and the convex dots correspond to each other.

[0004] The above structure uses a combination of concave and convex dots to process Braille on cardboard packaging. The mold is simply a combination of embossing molds. If the glass plate is also formed by extrusion, the glass plate needs to be softened before being bent and deformed at the Braille dots by extrusion. This requires a large extrusion force on the glass plate and is prone to cracking during the extrusion process, which makes it difficult to form Braille glass. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a mold for processing Braille glass. The technical problem to be solved by this invention is: how to solve the problem of forming difficulties caused by applying existing molds to Braille glass.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A mold for processing Braille glass includes a lower mold and an upper mold. The lower mold has a forming cavity, and the bottom of the forming cavity has multiple Braille holes that penetrate the lower mold vertically. The bottom of the upper mold has a protruding mold core that can be embedded in the forming cavity, with the outer wall of the mold core fitting against the cavity wall. The mold core has a planar forming surface that faces the inner bottom surface of the forming cavity.

[0008] The glass plate is placed in the forming cavity, and the entire mold is placed in a heating furnace for overall heating. The glass softens, the upper mold moves downward, and the mold core abuts against the glass and is gradually embedded into the forming cavity. Under pressure, the softened glass partially embeds into the Braille holes to form Braille protrusions. To ensure that the softened glass can quickly embed into the Braille holes during the pressing process, the Braille holes are vertically penetrating the upper mold, facilitating ventilation during forming. The softened glass can quickly embed into the Braille holes, and the Braille dots are less prone to deformation, improving the forming effect of the Braille glass. The above structure, through the cooperation of the forming cavity and the mold core, achieves the limitation of the softened glass plate, and the Braille holes are opened on the lower mold. The mold core has a planar forming surface, which ensures that the glass plate is subjected to the same pressure in all parts, making it easier for the softened glass to be uniformly pressed and embedded into the Braille holes, further improving the forming effect and stability of the Braille glass.

[0009] In the aforementioned mold for processing Braille glass, a central control hole is also provided in the middle of the bottom of the forming cavity, and the central control hole penetrates the lower mold vertically.

[0010] The central control hole allows the softened glass to be pressed into the central control hole when the mold core is pressed down. This position is the center of the control panel and also serves to position the Braille glass during installation. The central control hole is set to penetrate the lower mold vertically to facilitate ventilation and ensure the forming effect of the Braille glass, making it easier to form the central control protrusion.

[0011] In the aforementioned mold for processing Braille glass, the diameter of the Braille hole is 0.3 mm to 0.7 mm.

[0012] This structure allows the Braille holes to both allow for ventilation and prevent softened glass from overflowing, facilitating the formation of Braille embossed dots.

[0013] The optimal setting is to set the diameter of the Braille hole to 0.5mm.

[0014] In the aforementioned mold for processing Braille glass, the outer edge of the upper mold is provided with a plurality of spaced positioning blocks, which are located at each corner of the upper mold. The lower mold has an annular retaining edge, and the inner sidewall of the positioning block is in contact with the outer sidewall of the retaining edge.

[0015] The placement of positioning blocks and retaining edges makes the positioning of the lower and upper molds more convenient and accurate. Combined with the mutual limiting of the molding cavity and molding blocks, dual positioning of the lower and upper molds is achieved, improving the qualification rate of the molded finished products.

[0016] In the aforementioned mold for processing Braille glass, the retaining edge protrudes outward at both ends of the lower mold to form spacer blocks, which can be embedded between two adjacent positioning blocks.

[0017] The use of spacers makes the positioning between the edge and the positioning block more stable, improves the positioning effect, and increases the yield rate of Braille glass products.

[0018] In the aforementioned mold for processing Braille glass, a limiting step is provided on the outer wall of the retaining edge, and the positioning block is embedded in the limiting step and abuts against the limiting step.

[0019] The setting of the limiting step can further increase the contact area between the stop and the positioning block, resulting in a better positioning effect.

[0020] Compared with the prior art, the present invention has the following advantages: by cooperating with the forming cavity and the mold core, the softened glass plate is limited, and a Braille hole is opened on the lower mold, while the mold core has a planar forming surface, so that the glass plate is subjected to the same pressure in all parts, which facilitates the uniform extrusion of the softened glass into the Braille hole, further improving the forming effect and forming stability of Braille glass.

[0026] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] like Figure 1 and Figure 2 As shown, the mold used for processing Braille glass includes a lower mold 2 and an upper mold 3.

[0028] Specifically, such as Figure 1-4As shown, the lower mold 2 has a molding cavity 21, and the bottom of the molding cavity 21 has multiple blind holes 22. The blind holes 22 penetrate the lower mold 2 vertically. The bottom of the upper mold 3 has a protruding mold core 31. The mold core 31 can be embedded in the molding cavity 21 and the outer wall of the mold core 31 is in contact with the cavity wall of the molding cavity 21. The mold core 31 has a planar molding surface 32, which is directly opposite to the inner bottom surface of the molding cavity 21.

[0029] The glass plate is placed in the forming cavity 21, and the entire mold is placed in a heating furnace for overall heating. The glass softens, the upper mold 2 moves downward, and the mold core 31 abuts against the glass and is gradually embedded into the forming cavity 21. Under pressure, the softened glass partially embeds into the Braille hole 22 to form Braille bumps. To ensure that the softened glass can quickly embed into the Braille hole 22 during the pressing process, the Braille hole 22 is vertically penetrating the upper mold 2 to facilitate ventilation during forming. Within the perforation 22, the Braille dots are less prone to deformation, improving the forming effect of the Braille glass 1. The above structure achieves the limitation of the softened glass plate through the cooperation of the forming cavity 21 and the mold core 31. The lower mold 2 has a Braille hole 22, while the mold core 31 has a planar forming surface 32, so that the glass plate is subjected to the same pressure in all parts, which facilitates the uniform compression of the softened glass into the Braille hole 22, further improving the forming effect and forming stability of the Braille glass 1.

[0030] The raised dots in Braille represent Braille numerals, making it easier for blind people to operate mobile phones.

[0031] like Figure 1 and Figure 3 As shown, a central control hole 26 is also provided in the middle of the bottom of the molding cavity 21. The central control hole 26 penetrates the lower mold 2 vertically. The diameter of the Braille hole 22 is 0.3mm to 0.7mm, and the optimal diameter of the Braille hole 22 is 0.5mm.

[0032] like Figure 1 and Figure 2 As shown, the outer edge of the upper mold 3 is provided with a plurality of spaced positioning blocks 33, which are located at each corner of the upper mold 3. The lower mold 2 has an annular retaining edge 23. The inner sidewall of the positioning block 33 fits against the outer sidewall of the retaining edge 23. The retaining edge 23 protrudes outward at both ends of the lower mold 2 to form spacer blocks 24. The spacer blocks 24 can be embedded between two adjacent positioning blocks 33. A limiting step 25 is provided on the outer wall of the retaining edge 23. The positioning block 33 is embedded in the limiting step 25 and abuts against the limiting step 25.
