Description

Technical Field

[0001] The present invention belongs to the technical field of glass molds, and more specifically, relates to a mold for glass ornaments with hanging holes. Background Art

[0002] Currently, some existing glass articles need to be drilled to form hanging holes for hanging the glass articles and the like.

[0003] The molds for existing glass articles include an upper mold, a lower mold and a demolding mechanism. By pouring materials into the lower mold and pressing the upper mold against the lower mold, the molding of the glass article in the mold is completed. Finally, through the ejection of the demolding mechanism, the separation of the molded glass article from the mold is realized. Among them, for glass articles that need to be drilled, a fixed needle mold is provided in the lower mold, so that the glass article is drilled through the needle mold during the molding process.

[0004] However, during the molding process of the above fixed needle mold, the glass liquid in contact with the needle mold cools faster, resulting in different cooling rates between this part of the glass and other parts, and the finished product is fragile; at the same time, after the glass liquid contacts the needle mold, the needle mold is fixed and immovable. After the glass cools, it will adhere to the needle mold, and the glass ornament is fragile during demolding. Summary of the Invention

[0005] The present invention provides a mold for glass ornaments with hanging holes, which can avoid the problem of cracking at the hanging holes of glass ornaments and improve the qualified rate of finished products.

[0007] As a further improvement of the present invention, the counterweight balance includes a counterweight rod body, and the swing arm extends downward along the central part of the counterweight rod body; a counterweight block is arranged at one end of the counterweight rod body far from the pressing mechanism, so that the counterweight balance is inclined under normal conditions.

[0008] As a further improvement of the present invention, the needle die includes a movable block and a linkage rod; the movable block is embedded in the lower die, and the front end of the movable block is rotatably connected to the lower die around its axis; the linkage rod protrudes outside the lower die, and the linkage rod is movably connected in the limit groove of the swing arm; the hole needle is fixedly connected to the axis of the movable block to drive the hole needle to rotate through the rotation of the movable block.

[0009] As a further improvement of the present invention, the pressing mechanism includes a rod body, a clamping groove is opened at the front end of the rod body, a connecting rod is embedded in the clamping groove, and the connecting rod is fixedly arranged at the upper and lower ends of the clamping groove through fixing pieces respectively; a pressing piece is arranged at the lower end of the connecting rod, and the pressing piece is fixedly connected to the connecting rod, so that the pressing mechanism moves when the upper die is closed or opened.

[0010] As a further improvement of the present invention, a demolding mechanism is slidably connected in the lower die; the demolding mechanism includes a module and a movable rod, and the module matches the cavity formed in the lower die; a second through hole is opened on the module, and the position where the second through hole is opened in the lower die corresponds to the hole needle; the second through hole matches the hole needle; the movable rod is slidably connected to the middle part of the lower die.

[0011] As a further improvement of the present invention, a third through hole is opened on the upper die, and the opening position of the third through hole corresponds to the position of the hole needle in the lower die; the third through hole matches the hole needle; after the lower die and the upper die are closed, the hole needle enters the third through hole of the upper die, so that a cavity with a hanging hole is formed between the lower die and the upper die.

[0012] As a further improvement of the present invention, the number of the needle dies is set to be several, and several needle dies are arranged circumferentially around the lower die; the number of the counterweight balance and the pressing mechanism is the same as that of the needle die.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the linkage design of the upper die, the counterweight balance and the needle die, when the upper die presses down, it drives the counterweight block to tilt, drives the linkage rod and the movable block to swing, and through the closing and opening of the lower die and the upper die, the hole needle is forced to rotate multiple times in the mold cavity to form a mold. This design effectively solves the problem of low product yield caused by the adhesion of the hole needle to the glass material in the prior art. By swinging, the continuity of the path (the first through hole, the second through hole, the third through hole) of the hole die is maintained, ensuring a smooth molding process without residue, and significantly improving the processing product yield of the glass mold.

[0018] Specifically, a boss 11 is provided at the upper end of the base 1, and a first movable hole 12 is opened in the middle of the boss 11. The first movable hole 12 is matched with the demolding mechanism 3 so that the demolding mechanism 3 can be inserted into the first movable hole 12 and move.

[0019] Specifically, the lower mold 2 includes an upper pressing portion 21, a cavity 22, a swinging cavity 23, a second moving hole 24, and a groove 25. The upper pressing portion 21 is located at the upper end of the lower mold 2. The upper pressing portion 21 includes a telescopic cavity 211, an observation cavity 212, and a fixing cavity 213. The telescopic cavity 211 is opened on both sides of the upper end surface of the upper pressing portion 21, and the observation cavity 212 is located at the lower end of the telescopic cavity 211. The observation cavity 212 communicates with the telescopic cavity 211. The fixing cavity 213 is opened on the periphery of the observation cavity 212, and a plurality of fixing cavities 213 are provided to fix the lower mold 2 and the base 1 by passing fixing pins through the fixing cavities 213. The cavity 22 is opened in the middle of the lower mold 2. The cavity 22 is matched with the demolding mechanism 3, and first through holes 221 penetrating the wall of the lower mold 2 are opened at both ends of the cavity 22. The swinging cavity 23 is opened at the edge of the lower end surface of the lower mold 2 to form an opening. At least one swinging cavity 23 is provided, and the first through hole 221 penetrates the wall of the lower mold 2 and extends into the swinging cavity 23. Among them, the needle mold 6 is matched with the swinging cavity 23, and the needle mold 6 is rotatably connected to the swinging cavity 23. The second moving hole 24 is opened through the middle of the cavity 22, and the second moving hole 24 penetrates the wall of the lower mold 2. The groove 25 is opened in the middle of the lower end of the lower mold 2, and the groove 25 is matched with the boss 11 so that the lower mold 2 can be completely abutted against the base 1.

[0020] Specifically, the demolding mechanism 3 includes a module 31 and a movable rod 32. The module 31 is matched with the cavity 22. A second through hole 312 corresponding to the first through hole 221 is opened on the module 31, and the first through hole 221 is matched with the second through hole 312. A mold groove 311 is opened in the middle of the module 31. The mold groove 311 is matched with the upper mold 4 at the upper end to realize shaping in the mold. The movable rod 32 is embedded in the first moving hole 12 and the second moving hole 24, and the movable rod 32 is slidably connected to the first moving hole 12 and the second moving hole 24 to eject the formed glassware through the demolding mechanism 3.

[0021] Specifically, the upper mold 4 includes a mold pressing seat 41, a connecting portion 42, and a downward pressing mechanism 43. The mold pressing seat 41 is located at the upper end of the lower mold 2. On both sides of the lower end of the mold pressing seat 41, alignment rods 411 are provided, and the alignment rods 411 are mutually matched with the telescopic cavities 211. The alignment rods 411 are slidably connected to the telescopic cavities 211. In the middle of the mold pressing seat 41, an alignment module 412 is provided, and the alignment module 412 is mutually matched with the module 31. A third through hole 413 is also provided in the alignment module 412. The first through hole 221, the second through hole 312, and the third through hole 413 are arranged in corresponding positions and are mutually matched. The connecting portion 42 is provided at the upper end of the mold pressing seat 41, and a connecting hole 421 is provided in the middle of the connecting portion 42. The connecting hole 421 is connected to the output end at the upper end of the operating table. The output end at 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. The downward pressing mechanism 43 is provided at the upper edge of the mold pressing seat 41. The downward pressing mechanism 43 includes a rod body, and the rod body is fixedly connected to the edge of the mold pressing seat 41. A clamping groove 431 is provided at the front end of the rod body, and a connecting rod 432 is embedded in the clamping groove 431. The connecting rod 432 is fixedly arranged at the upper and lower ends of the clamping groove 431 through fixing pieces respectively, so as to limit and fix the connecting rod 432. A downward pressing piece 433 is provided at the lower end of the connecting rod 432, and the downward pressing piece 433 is fixedly connected to the connecting rod 432, so that when the upper mold 4 moves in the height direction, it drives the downward pressing mechanism 43 to move.

[0022] Specifically, the counterweight balance 5 includes a counterweight rod body and a swing arm 51 extending downward along the central part of the counterweight rod body. The swing arm 51 is integrally formed with the counterweight rod body, and a limiting groove is provided at the lower end of the swing arm 51. A counterweight block 52 is provided at one end of the counterweight rod body away from the downward 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 inclined. The center of the counterweight rod body is rotatably connected to the outer side wall of the lower mold 2, so that when the downward pressing mechanism 43 moves in the height direction, it presses against the counterweight balance 5, and the inclination state of the counterweight balance is changed through the center of the counterweight balance 5. The moving range of the downward pressing mechanism 43 includes the position where the light end of the counterweight balance 5 is located under normal conditions.

[0023] Specifically, the needle mold 6 is located in the swing cavity 23, and 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, and the front end of the movable block 61 is rotatably connected around its axis in the swing cavity 23 of the lower mold 2. The linkage rod 62 protrudes from the swing cavity 23, and the linkage rod 62 is movably connected in the limit groove of the swing arm 51. Under normal circumstances, when the counterweight block 52 is pressed to tilt one side of the counterweight balance 5, 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 hole pin 611 is disposed at the front end axis of the movable block 61, and the hole pin 611 is fixedly connected to the movable block 61. The hole pin 611 matches the first through hole 221, the second through hole 312, and the third through hole 413, so that the hole pin 611 passes through the first through hole 221, the second through hole 312, and the third through hole 413. Since the hole pin 611 is fixedly connected to the movable block 61, the movable block 61 drives the hole pin 611 to rotate.

[0024] It should be noted that when this part is used, when the mold is first closed, the upper mold 4 is moved in the direction of the lower mold 2 to press the module 31 and the alignment module 412 to correspond to each other. Among them, the hole needle 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. At the same time, the pressing mechanism 43 at the side end of the upper mold 4 presses the counterweight balance 5 during the pressing process to press up the counterweight balance 5 at one end of the counterweight block 52. When the counterweight balance 5 at one end of the counterweight block 52 is pressed up, the swing arm 51 of the counterweight balance 5 is pressed and swung to drive the linkage rod 62 to swing and link the hole needle 611 to rotate, so as to prevent the hole needle 611 from causing adhesion after the hole is formed in the cavity formed by the module 31 and the alignment module 412.

[0025] Working principle: The mold for glass ornaments with hanging holes drives the demoulding mechanism in the lower mold to press together when the upper mold is pressed down. At the same time, the pressing mechanism presses against the counterweight block of the counterweight balance, so that the counterweight block is tilted and drives the linkage rod to rotate through the limit groove. The linkage rod drives the movable block to swing in the swing cavity, so that the hole needle fixed on the movable block passes through the first through hole of the lower mold, the second through hole of the demoulding mechanism and the third through hole of the upper mold, and drives the hole needle to rotate during the swing of the swing arm to complete the forming of the hole in the mold to avoid the hole needle and the glass material from sticking. Finally, when the upper mold is opened, the pressing mechanism no longer presses against the counterweight balance, so that the heavy end of the counterweight balance is pressed down to restore the initial tilted state, and at the same time, the swing arm swings again to drive the hole needle to rotate in the opposite direction to completely complete the hole forming after the mold is opened.

[0026] Specific Embodiment 2: Different from Specific Embodiment 1, in this embodiment, a plurality of needle dies 6 are provided, and the plurality of needle dies 6 are arranged circumferentially around the lower die 2. Among them, the number of swing cavities 23 opened circumferentially in the corresponding lower die 2 corresponds to the number of needle dies 6 to keep the number of swing cavities 23 consistent with that of the needle dies 6. Finally, the number of counterweight balances 5 and pressing mechanisms 43 provided is consistent with that of the needle dies 5.

[0027] It should be noted here that through the setting of a plurality of needle dies 6, it is applicable to the number of hanging holes required for different glass ornaments.
