Description

Technical Field

[0001] The utility model belongs to the technical field of glass cups, and specifically relates to a glass cup mold. Background Art

[0002] The production of glass cup bodies generally requires the use of a glass press, which is used to stamp the bottom into shape. After annealing, the excess bottom is cut off using diamond slicing, and the finished product is completed after a series of processes such as polishing.

[0003] During the stamping production process, due to the needs of the stamping process, the glass cup has a bottom. The bottom of the glass cup is usually an unnecessary part, so it is necessary to cut the bottom of the cup. After cutting, the cup body is ground and polished, and the production of the glass cup is completed.

[0004] The patent number is 202110917708.8, and a public specification published on February 9, 2024 discloses a glass cup forming mold, in which the inner mold is located on the base, and the inner mold has a cavity extending from the top to the bottom. The base is provided with a vertically arranged rotating shaft, and the rotating shaft is located on one side of the inner mold. One end of the left clamp and the right clamp are rotatably connected to the base through the rotating shaft to hold the inner mold between the two; one end of the die core extends into the inner mold to form a cup body cavity between the outer wall of the die core and the inner wall of the inner mold. With the above-mentioned optimized design of the glass cup forming mold, the left and right clamps are rotatably mounted on the base through the rotating shaft, so that the three form an integrated structure. The left and right clamps hold the inner mold from both sides, which facilitates the precise positioning of the inner mold during molding. At the same time, during the injection process of the glass raw materials, the left and right clamps provide circumferential support for the side walls of the inner mold, thereby extending the service life of the inner mold.

[0005] In the prior art, since the bottom of the cup is connected to the cup body, a diamond cutter is usually needed to cut the bottom of the cup directly from the cup body from the side of the glass cup. This cutting method requires cutting tools, grinding tools, etc., requires a lot of production equipment, and wastes a lot of glass liquid materials. Grinding also produces a lot of waste chips, and the working environment is poor, which affects the health of workers. Utility Model Content

[0021] The following is a further detailed description of the specific implementation methods of the utility model by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution of the utility model and facilitating its implementation.

[0022] See also Figure 1-2 A glass cup mold includes a bottom mold 1 and a punch head 2. The bottom mold 1 includes a bottom plate 11 and a sealing plate 12 arranged on the bottom plate 11. The bottom plate 11 is provided with a lower arc groove 4. The punch head 2 is a column. The bottom of the punch head 2 is provided with an upper arc groove 3. When the mold is closed, there is a gap between the punch head 2 and the bottom plate 11.

[0023] The glass cups produced by this mold can transform the traditional thick bottom of the glass cup into an inner bottom that is located inside the glass cup, thick in the middle and thin at the edges. Compared with the traditional glass cup, the inner bottom is easier to cut. You only need to use a flame to soften the edge and then use a cutter to cut the inner bottom off in one go. This can not only improve the efficiency of cutting unnecessary structures and the utilization rate of glass liquid, but also reduce the cost of post-processing, improve efficiency, save costs, improve product quality, and reduce the generation of debris, which is conducive to improving the quality of the production environment.

[0024] The sealing plates 12 are arranged in pairs, and the sealing plates 12 are rotatable relative to each other; the produced glass cups can be taken out through the rotating sealing plates 12.

[0025] When the mold is closed, there is a gap between the punching head 2 and the sealing plate 12; the gap between the punching head 2 and the sealing plate 12 is the wall of the glass, and the gap between the sealing plate 12 and the bottom plate 11 ensures that the inner bottom of the glass can be formed inside the glass to avoid appearing at the bottom of the glass, resulting in no obvious dividing line between the inner bottom and the glass itself, which will affect the shape of the surface of the glass when heated and affect the production quality.

[0026] The sealing plate 12 is arc-shaped, and adjacent sealing plates 12 are connected via a rotating motor; the rotating motor is used to control the opening and closing of the sealing plate 12.

[0027] A pressing plate 5 is provided on the outside of the punch head 2, and a groove 6 matching with the pressing plate 5 is provided on the top of the sealing plate 12; the top of the mold is sealed by the pressing plate 5, so that the glass cup is formed into a more standard shape and the generation of bubbles is reduced.

[0028] A sleeve 7 is provided on the top of the pressing plate 5, and the sleeve 7 is sleeved on the outside of the punching head 2, so that the pressing plate 5 does not affect the normal descent of the punching sleeve.

[0029] A limit plate 8 is provided on the outer side of the pressing plate 5 ; the limit plate 8 is used to limit the height to which the pressing plate 5 descends.

[0030] The bottom plate 11 and the punch head 2 are provided with vent holes 9 for exhausting gas.

[0031] The glass cup is made by using a glass press, on which a bottom mold 1, a punch head 2 and a sleeve 7 are arranged; and the glass cup is produced by using the glass press.

[0032] Since arc grooves are provided on the punch head 2 and the bottom plate 11, when they are closed together, the glass liquid exists between the arc grooves, which will form a thick-walled part in the middle of the inner bottom, and the gap between the punch head 2 and the bottom plate 11 is the thin-walled part of the inner wall edge. The thin-walled part is connected to the cup body of the glass. The thick-walled part in the middle is 8.5 mm thick, and the thin-walled part is 2.5 mm thick. When heating, the thin-walled part is heated to quickly soften the thin wall. Since the inner bottom is located inside the glass, only the shape of the thin-walled part will be affected during heating. When cutting, only the thin-walled part needs to be cut, which is convenient for cutting and avoids deformation of the glass body. The burrs on the inner wall surface of the glass after cutting can be removed by flame polishing, which is convenient and practical. Compared with the traditional cutting of the cup bottom, less waste is generated, and the amount of glass liquid required for producing the glass is also less, reducing costs.

[0033] The technical effect of the utility model is that the glass cup produced by the mold can transform the traditional thick bottom of the glass cup into an inner bottom located inside the glass cup, which is thick in the middle and thin at the edge. Compared with the traditional glass cup, the inner bottom is more convenient to cut. It only needs to use flame to soften the edge and then use a cutter to cut the inner bottom at one time. This can not only improve the efficiency of cutting unnecessary structures and the utilization rate of glass liquid, but also reduce the cost of later processing, improve efficiency, save costs, improve product quality, and reduce the generation of debris, which is conducive to improving the quality of the production environment.

[0034] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
