[0001] The utility model relates to the technical field of molds, in particular to a mold of a frameless lamp. Background Art

[0002] A search revealed a Chinese patent with publication number CN219096001U, which discloses a high-efficiency pressing mold for LED lamps. Specifically, it relates to the field of pressing molds and includes a workbench, legs, and a fixed mold. The workbench has legs mounted at the bottom, a fixed mold at the top, and two symmetrical bases mounted on the workbench, each with a demolding assembly mounted on it. The workbench is also equipped with multiple support rods, each supporting a top plate mounted on its top. A pressing mechanism is mounted on the top plate, and a buffer assembly is connected to the bottom of the pressing mechanism. The bottom of the buffer assembly is connected to a movable mold. This patent has the advantages of being able to efficiently press lampshades for LED lamps and quickly demold the finished pressed product for easy removal, thereby improving overall production efficiency.

[0003] In the above-mentioned prior art solution, the cylinders on both sides are operated to enable the push rod to push the scraper to move toward the fixed mold, and the finished lampshade attached to the movable mold is separated from the movable mold under the obstruction of the scrapers on both sides, thereby completing the demolding; however, in actual use, if the movable mold moves to a higher position, the scraper is likely to be directly squeezed on the side wall of the lampshade, causing the lampshade to deform; when the movable mold moves to a lower position, the scraper will be directly pressed on the side wall of the mold, which is likely to cause damage to the mold. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a mold for a frameless lamp. When the mounting plate moves upward along with the output end of the hydraulic pump, the air inside the air storage tube is output outward and blown onto the side wall of the top mold, blowing out the material on the side wall of the top mold, thereby achieving the effect of automatic unloading.

[0005] The technical solution to achieve the purpose of the utility model is: a mold for a frameless lamp, comprising a workbench, a supporting leg is fixedly installed on the bottom wall of the workbench, the top wall of the workbench is fixedly installed with a mounting column, the top wall of the mounting column is fixedly installed with a fixing plate, a hydraulic pump is fixedly installed on the side wall of the fixing plate, the output end of the hydraulic pump is fixedly installed with a mounting plate, a top mold is fixedly installed on the bottom wall of the mounting plate, the top wall of the workbench is fixedly installed with a bottom mold, the bottom mold and the top mold are aligned with each other, an air storage pipe is fixedly installed on the bottom wall of the fixing plate, a ventilation pipe is slidably installed inside the air storage pipe, the bottom end of the ventilation pipe is fixedly installed on the top wall of the mounting plate, an air outlet groove is provided on the side wall of the mounting plate, the top of the air outlet groove is aligned with the inside of the ventilation pipe, the bottom end of the air outlet groove is provided with an air gathering groove, the bottom end of the air gathering groove is aligned with the side wall of the top mold, and the top wall of the ventilation pipe is provided with a ventilation groove.

[0006] In certain embodiments, a push rod is fixedly mounted on the inner top wall of the gas storage tube, a sealing gasket is slidably mounted inside the ventilation groove, and the push rod slides through the side wall of the sealing gasket.

[0007] In some embodiments, an air flow groove is provided inside the push rod, and positioning grooves are provided at the upper and lower ends of the air flow groove, and the two positioning grooves are respectively located at the upper and lower ends of the sealing gasket.

[0008] In some embodiments, the gas gathering groove is a frustum-shaped groove with a radius that decreases toward the bottom end.

[0009] In some embodiments, a fixing rod is fixedly mounted on the inner side wall of the ventilation tube, and the bottom end of the top rod slides through the interior of the fixing rod.

[0010] In some embodiments, a reinforcement rod is fixedly mounted on the side wall of the mounting column, and the top end of the reinforcement rod is fixedly connected to the bottom wall of the fixing plate.

[0011] Compared with the prior art, the present invention has the following significant advantages:

[0012] First: The utility model places the material on the top of the bottom mold, and then moves the mounting plate downward through the extension of the output end of the hydraulic pump, so that the top mold is stuck in the inside of the bottom mold to perform the molding operation on the material. When the mounting plate moves downward, the ventilation pipe will move downward with the mounting plate, and the external air enters the inside of the air storage pipe through the air gathering groove, the air outlet groove and the ventilation groove. When the mounting plate moves upward with the output end of the hydraulic pump, the air inside the air storage pipe is output outward through the ventilation groove, the air outlet groove and the air gathering groove, and the bottom end of the air gathering groove is aligned with the side wall of the top mold, so the air output outward through the air gathering groove will blow on the side wall of the top mold, blowing out the material on the side wall of the top mold, thereby achieving the effect of automatic unloading; it solves the problem that the material or mold is easily damaged during the demolding process of the existing mold.

[0013] Second: In the utility model, when the vent pipe moves downward together with the mounting plate, the air inside the vent pipe will push the sealing gasket to move upward, so that the sealing gasket is separated from the inside of the vent groove, and the air inside the vent pipe enters the inside of the air storage pipe. When the vent pipe moves upward together with the mounting plate, the sealing gasket moves downward and fits tightly against the inner wall of the vent groove, compressing the air inside the air storage pipe until the two positioning grooves are respectively located at the upper and lower ends of the sealing gasket. The high-pressure air inside the air storage pipe therefore enters the interior of the vent pipe through the positioning groove and the air string groove, and the high-pressure air is then discharged outward through the vent pipe, the air outlet groove and the air gathering groove, thereby further improving the material removal efficiency.

The bottom end is aligned with the side wall of the top mold 10, and a ventilation groove 13 is provided on the top wall of the ventilation pipe 9; the material is placed on the top of the bottom mold 6, and then the mounting plate 5 is moved downward by extending the output end of the hydraulic pump 4, so that the top mold 10 is stuck in the inside of the bottom mold 6 to perform a molding operation on the material. When the mounting plate 5 moves downward, the ventilation pipe 9 will move downward with the mounting plate 5, and the external air enters the interior of the air storage pipe 8 through the air gathering groove 12, the air outlet groove 11 and the ventilation groove 13. When the mounting plate 5 moves upward with the output end of the hydraulic pump 4, the air inside the air storage pipe 8 is discharged outward through the ventilation groove 13, the air outlet groove 11 and the air gathering groove 12, and the bottom end of the air gathering groove 12 is aligned with the side wall of the top mold 10, so the air output outward through the air gathering groove 12 will blow on the side wall of the top mold 10, blowing out the material on the side wall of the top mold 10, achieving the effect of automatic unloading.

[0024] like Figures 1-4As shown, in one embodiment, in order to facilitate the blowing out of the material on the side wall of the top mold 10, the air gathering groove 12 is a truncated cone-shaped groove with a smaller radius as it approaches the bottom end; the cross-sectional area of ​​the bottom end of the air outlet groove 11 is reduced by the air gathering groove 12, the strength of the air flow output outward is increased, and the lamp is conveniently dropped from the side wall of the top mold 10; a top rod 18 is fixedly installed on the top wall of the inner top of the gas storage tube 8, and a sealing gasket 14 is slidably installed inside the ventilation groove 13. The top rod 18 slides through the side wall of the sealing gasket 14, and an air string groove 16 is provided inside the top rod 18. The upper and lower ends of the air string groove 16 are provided with positioning grooves 17, and the two positioning grooves 17 are respectively located at the upper and lower ends of the sealing gasket 14; when the ventilation tube 9 moves downward with the mounting plate 5, the air inside the ventilation tube 9 will push the sealing gasket 14 to move upward, so that the sealing gasket 14 is separated from the interior of the ventilation groove 13, and the air inside the ventilation tube 9 therefore enters the interior of the gas storage tube 8. When the ventilation tube 9 moves upward with the mounting plate 5, The sealing gasket 14 moves downward and fits tightly against the inner wall of the ventilation groove 13, compressing the air inside the air storage pipe 8 until the two positioning grooves 17 are respectively located at the upper and lower ends of the sealing gasket 14. The high-pressure air inside the air storage pipe 8 therefore enters the interior of the ventilation pipe 9 through the positioning groove 17 and the air string groove 16, and the high-pressure air is then discharged outward through the ventilation pipe 9, the air outlet groove 11 and the air gathering groove 12, and the high-pressure air is further improved by the dematerialization efficiency; a fixing rod 15 is fixedly installed on the inner wall of the ventilation pipe 9, and the bottom end of the push rod 18 slides through the interior of the fixing rod 15; the position of the push rod 18 is limited by the fixing rod 15 to ensure that the position of the push rod 18 is stable; a reinforcement rod 19 is fixedly installed on the side wall of the mounting column 3, and the top end of the reinforcement rod 19 is fixedly connected to the bottom wall of the fixing plate 2; the reinforcement rod 19 is used to form a triangle between the fixing plate 2 and the mounting column 3, so that the reinforcement rod 19 can reinforce the position of the fixing plate 2 to ensure that the position of the fixing plate 2 is stable.

[0025] The specific working method is: place the material on the top of the bottom mold 6, and then move the mounting plate 5 downward through the extension of the output end of the hydraulic pump 4, so that the top mold 10 is stuck in the inside of the bottom mold 6 to perform a molding operation on the material. When the mounting plate 5 moves downward, the vent pipe 9 will move downward with the mounting plate 5, and the external air enters the inside of the air storage pipe 8 through the air gathering groove 12, the air outlet groove 11 and the vent groove 13. When the mounting plate 5 moves upward with the output end of the hydraulic pump 4, the air inside the air storage pipe 8 is output outward through the vent groove 13, the air outlet groove 11 and the air gathering groove 12, and the bottom end of the air gathering groove 12 is aligned with the side wall of the top mold 10, so the air output outward through the air gathering groove 12 will blow on the side wall of the top mold 10, blowing out the material on the side wall of the top mold 10, thereby achieving the effect of automatic unloading.
