Description

Technical Field

[0001] This utility model belongs to the field of glass mold technology, and more specifically, relates to a mold for glass ornaments with hanging holes. Background Technology

[0002] Currently, some existing glass products require holes to be drilled to create hanging holes for suspending the glass products.

[0003] Existing glass product molds include an upper mold, a lower mold, and a demolding mechanism. Material is poured into the lower mold, and the upper mold presses against the lower mold to form the glass product within the mold. Finally, the demolding mechanism ejects the formed glass product from the mold. For glass products requiring openings, the lower mold contains fixed pin molds to allow the openings to be made during the forming process.

[0004] However, during the molding process, the molten glass in contact with the fixed mold cools down faster, resulting in a different cooling rate between this part of the glass and other parts, making the finished product fragile. At the same time, since the mold is fixed after the molten glass comes into contact with it, the glass will stick to the mold after cooling, making the glass ornament fragile when demolded. Utility Model Content

[0005] This invention provides a mold for glass ornaments with hanging holes, which can prevent the glass ornaments from breaking at the hanging holes and improve the yield of finished products.

The upper mold is fixedly mounted on the outer wall of the upper mold so that it can move synchronously with the upper mold; the movement range of the pressing mechanism includes the normal position of the light end of the counterweight balance so that it can drive the counterweight balance to rotate after pressing it; the needle mold is located inside the lower mold, and the inner end of the needle mold is rotatably connected to the lower mold around its axis; the hole needle is concentrically fixed on the upper side of the inner end of the needle mold, and the upper part of the hole needle is located inside the cavity to serve as the core of the hanging hole for glass ornaments; the outer end of the needle mold is located outside the lower mold and is always located in the limiting groove of the swing arm and is movably connected to the limiting groove.

[0007] As a further improvement of this utility model, the counterweight balance includes a counterweight rod, and a swing arm extends downward along the center of the counterweight rod; a counterweight block is provided at the end of the counterweight rod away from the pressing mechanism so that the counterweight balance is kept tilted under normal conditions.

[0008] As a further improvement of this utility model, the needle mold includes a movable block and a linkage rod; the movable block is embedded in the lower mold, and the front end of the movable block is rotatably connected to the lower mold around its axis; the linkage rod protrudes from the outside of the lower mold and is movably connected to the limiting groove of the swing arm; the needle is fixedly connected to the axis of the movable block so as to drive the needle to rotate through the rotation of the movable block.

[0009] As a further improvement of this utility model, the pressing mechanism includes a rod body, a snap-fit ​​groove is provided at the front end of the rod body, a connecting rod is embedded in the snap-fit ​​groove, and the connecting rod is fixedly set at the upper and lower ends of the snap-fit ​​groove by fixing plates respectively; a pressing plate is provided at the lower end of the connecting rod, and the pressing plate is fixedly connected to the connecting rod so that the pressing mechanism is moved when the upper mold is closed or opened.

[0010] As a further improvement of this utility model, a demolding mechanism is slidably connected inside the lower mold; the demolding mechanism includes a module and a movable rod, the module and the cavity formed inside the lower mold are matched with each other; a second through hole is opened on the module, the position of the second through hole inside the lower mold corresponds to the hole pin; the second through hole and the hole pin are matched with each other; the movable rod is slidably connected to the middle of the lower mold.

[0011] As a further improvement of this utility model, a third through hole is provided on the upper mold, and the position of the third through hole corresponds to the position of the pin in the lower mold; the third through hole and the pin match each other; after the lower mold and the upper mold are closed, the pin enters the third through hole of the upper mold, so that a cavity with a hanging hole is formed between the lower mold and the upper mold.

[0012] As a further improvement of this utility model, the number of needle molds is set to several, and the several needle molds are arranged around the lower mold circumferentially; the number of counterweight balance and pressing mechanism is consistent with the number of needle molds.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] By linking the upper mold, counterweight balance, and needle mold, the upper mold tilts the counterweight when it presses down, causing the linkage rod and movable block to swing. Through the closing and opening of the lower and upper molds, the needle is forced to rotate multiple times within the mold cavity to form the mold. This design effectively solves the problem of low yield caused by the needle sticking to glass material in existing technologies. By maintaining the continuous flow of the mold path (first through hole, second through hole, third through hole) through the swinging motion, it ensures a smooth molding process without residue, significantly improving the yield of glass mold processing.

[0028] Specifically, the lower mold 2 includes an upper pressing part 21, a mold cavity 22, a swing cavity 23, a second movable hole 24, and a groove 25. The upper pressing part 21 is located at the upper end of the lower mold 2. The upper pressing part 21 includes a telescopic cavity 211, an observation cavity 212, and a fixed cavity 213. The telescopic cavity 211 is opened on both sides of the upper end face of the upper pressing part 21, and the observation cavity 212 is located at the lower end of the telescopic cavity 211, and the observation cavity 212 communicates with the telescopic cavity 211. The fixed cavity 213 is opened on the periphery of the observation cavity 212, and multiple fixed cavities 213 are provided to fix the lower mold 2 and the base 1 by passing a fixing pin through the fixed cavity 213. The mold cavity 22 is opened in the middle of the lower mold 2, and the mold cavity 22 matches the demolding mechanism 3. The two ends of the mold cavity 22 are provided with first through holes 221 that penetrate the wall of the lower mold 2. The swing cavity 23 is opened on the edge of the lower end face of the lower mold 2 to form an opening. At least one swing cavity 23 is provided, and a first through hole 221 penetrates the wall of the lower mold 2 and is located in the swing cavity 23. The needle mold 6 is matched with the swing cavity 23 and is rotatably connected to it. A second movable hole 24 is provided in the middle of the mold cavity 22 and penetrates the wall of the lower mold 2. A groove 25 is provided in the middle of the lower end of the lower mold 2, and the groove 25 matches the boss 11 so that the lower mold 2 can completely abut against the base 1.

[0029] Specifically, the demolding mechanism 3 includes a module 31 and a movable rod 32. The module 31 is matched with the mold cavity 22. The module 31 has a second through hole 312 corresponding to the first through hole 221, and the first through hole 221 and the second through hole 312 are matched. A mold groove 311 is formed in the middle of the module 31, and the mold groove 311 is matched with the upper mold 4 at the upper end to realize the shaping within the mold. The movable rod 32 is embedded in the first movable hole 12 and the second movable hole 24, and the movable rod 32 is slidably connected to the first movable hole 12 and the second movable hole 24 to eject the formed glass product through the demolding mechanism 3.

[0030] Specifically, the upper mold 4 includes a pressure mold base 41, a connecting part 42, and a pressing mechanism 43. The pressure mold base 41 is located at the upper end of the lower mold 2.

An alignment module 412 is provided in the middle of the pressure mold base 41, and the alignment module 412 is matched with module 31. A third through hole 413 is also provided on the alignment module 412. The positions of the first through hole 221, the second through hole 312, and the third through hole 413 are correspondingly provided and matched. The connecting part 42 is located at the upper end of the pressure mold base 41, and a connecting hole 421 is provided in the middle of the connecting part 42. The connecting hole 421 is connected to the output end of the upper end of the operating table. The output end of the upper end of the operating table has the ability to move in the height direction, so as to drive the upper mold 4 to move in the height direction through the operating table. A pressing mechanism 43 is disposed on the upper edge of the mold base 41. The pressing mechanism 43 includes a rod body, which is fixedly connected to the edge of the mold base 41. A snap-fit ​​groove 431 is provided at the front end of the rod body, and a connecting rod 432 is embedded in the snap-fit ​​groove 431.

A pressing plate 433 is provided at the lower end of the connecting rod 432. The pressing plate 433 is fixedly connected to the connecting rod 432 so that when the upper mold 4 moves in the height direction, it drives the pressing mechanism 43 to move.

[0031] Specifically, the counterweight balance 5 includes a counterweight rod and a swing arm 51 extending downwards along the center of the counterweight rod. The swing arm 51 is integrally formed with the counterweight rod, and a limit groove is formed at the lower end of the swing arm 51. A counterweight block 52 is provided at the end of the counterweight rod away from the pressing mechanism 43, so that one end of the counterweight balance 5 is the heavy end and the other end is the light end. Under normal conditions, the counterweight balance 5 is tilted. The center of the counterweight rod is rotatably connected to the outer wall of the lower mold 2, so that when the pressing mechanism 43 moves in the height direction, it presses against the counterweight balance 5, and the tilt state of the counterweight balance is changed by the center of the counterweight balance 5. The range of movement of the pressing mechanism 43 includes the position of the light end of the counterweight balance 5 under normal conditions.

[0032] Specifically, the needle mold 6 is located within the swing cavity 23. The needle mold 6 includes a movable block 61 and a linkage rod 62. The movable block 61 is embedded in the swing cavity 23 of the lower mold 2, and the front end of the movable block 61 matches the front end of the swing cavity 23. The front end of the movable block 61 is rotatably connected within the swing cavity 23 of the lower mold 2 around its axis. The linkage rod 62 protrudes from the swing cavity 23 and is movably connected to the limiting groove of the swing arm 51. Under normal conditions, when the counterweight 52 presses against the counterweight balance 5 and tilts to one side, the linkage rod 62 is rotated by the counterweight balance 5 to turn the movable block 61 to the other side of the swing cavity 23. A pin 611 is provided at the front axis of the movable block 61. The pin 611 is fixedly connected to the movable block 61 and matches the first through hole 221, the second through hole 312, and the third through hole 413 so that the pin 611 passes through the first through hole 221, the second through hole 312, and the third through hole 413. Since the pin 611 is fixedly connected to the movable block 61, the movable block 61 drives the pin 611 to rotate.

[0033] It should be noted that during use, when the mold is closed, the upper mold 4 moves towards the lower mold 2 to align module 31 and alignment module 412 for molding. The pin 611 is embedded in the upper mold 4 along the second through hole 312 and the third through hole 413 to form a complete cavity. Simultaneously, the pressing mechanism 43 on the side of the upper mold 4 presses against the counterweight balance 5 during the pressing process, lifting one end of the counterweight block 52. When the counterweight balance 5 at one end of the counterweight block 52 is lifted, the swing arm 51 of the counterweight balance 5 swings under pressure, causing the linkage rod 62 to swing and the pin 611 to rotate, preventing the pin 611 from sticking together in the cavity formed by the module 31 and alignment module 412 after molding.

[0034] Working principle:

[0035] This type of mold for glass ornaments with hanging holes uses a mechanism that presses down on the upper mold to drive the demolding mechanism in the lower mold to close. Simultaneously, the pressing mechanism presses against the counterweight of the balance, causing the counterweight to tilt and, through a limiting groove, rotate the linkage rod. The linkage rod drives a movable block to swing within the swing cavity, allowing a pin fixed to the movable block to penetrate the first through hole in the lower mold, the second through hole in the demolding mechanism, and the third through hole in the upper mold. As the swing arm swings, the pin rotates, completing the hole formation in the mold and preventing the pin from sticking to the glass material. Finally, when the upper mold opens, the pressing mechanism stops pressing against the balance, causing the heavier end of the balance to press down, restoring its initial tilt. Simultaneously, the swing arm swings again, causing the pin to rotate in the opposite direction, completely completing the hole formation after mold opening.

[0036] Specific Embodiment Two: Unlike Specific Embodiment One, in this embodiment, the number of needle molds 6 is set to a plurality, which are arranged circumferentially around the lower mold 2. The number of swing cavities 23 corresponding to the number of needle molds 6 in the lower mold 2 is kept consistent with the number of needle molds 6. Finally, the number of counterweight balances 5 and pressing mechanisms 43 is consistent with the number of needle molds 5.

[0037] It should be noted that by setting several needle molds 6, the number of hanging holes required for different glass ornaments can be adapted.
