Description

Technical Field

[0001] The utility model relates to the technical field of lantern production, in particular to a needle punching mould for a boneless lantern. Background Art

[0002] The boneless lantern is one of China's traditional handicrafts, which originated in the Tang Dynasty. The peculiarity of the boneless lantern is that the lamp body has no frame. It is made entirely of lamp pieces with various patterns pierced by embroidery needles and glued together. The patterns on the lamp surface are made by holes pierced by knives and needles, and light is passed through and left behind. The ever-changing shapes and rich patterns have formed a wide variety of colors and patterns.

[0003] In order to improve the production efficiency of boneless lanterns, a needle-piercing mold is used in the prior art to perform a needle-piercing operation on the lamp piece. The existing needle-piercing mold has a fixed structure and cannot adapt to the piercing of cardboards of different thicknesses. Moreover, it is inconvenient to replace the needle-piercing mold after it is worn. A Chinese patent document with the publication number "CN208411242U" discloses a boneless lantern needle-piercing combined mold, which is formed by screwing a threaded block evenly on the upper mold base, and the bottom of the threaded block is provided with a needle piercing that penetrates the upper mold base. The bottom of the needle piercing is exposed from the upper mold base, and the height of the needle piercing exposed from the bottom of the upper mold base (1) is adjusted by rotating the threaded block, so as to adapt to cardboards of different thicknesses, and facilitate the removal and disassembly of the needle piercing. However, in this way, there are many needle piercings on the needle-piercing mold. During installation, it is difficult to ensure that the lengths of the many needle piercings extending from the upper mold base are consistent, and the threaded block corresponding to each needle piercing needs to be rotated and adjusted, which makes installation cumbersome, inefficient, and inconvenient to disassemble and assemble. Utility Model Content

DETAILED DESCRIPTION

[0019] With reference to the accompanying drawings, specific embodiments of the present invention will be described in detail.

[0020] Reference Figure 1 to Figure 2 The utility model provides a first embodiment of a needle punching mold for a boneless flower lantern.

[0021] A needle punching mold for a boneless flower lantern comprises an upper die base 1 and a lower die base 2 corresponding to the upper die base 1. The upper die base 1 and the lower die base 2 are movably connected via a telescopic cylinder 3. The upper die base 1 is used to install a needle punching assembly 4, and the lower die base 2 is used to place a light sheet and a cardboard. The telescopic cylinder 3 drives the upper die base 1 to move toward the lower die base 2, and then drives the needle punching assembly 4 on the upper die base 1 to perform a needle punching operation on the light sheet and the cardboard on the lower die base 2.

[0022] The top of the upper mold base 1 is provided with a plurality of acupuncture installation grooves 11 and through holes 12 corresponding to the acupuncture installation grooves 11. A support block 13 is movably provided in the acupuncture installation groove 11. A through hole is provided in the center of the support block 13. The support block 13 is connected to the bottom of the acupuncture installation groove 11 through a compression elastic member 14. Preferably, the compression elastic member 14 adopts a compression spring.

[0023] The support block 13 is movably provided with a needling assembly 4. When the needling assembly 4 is placed on the support block 13, the lower end of the steel needle 41 of the needling assembly 4 is movably passed through the through hole and the through hole 12 on the support block 13 and extends to the bottom outer side of the upper mold base 1. Under normal conditions, the compression elastic member 14 between the support block 13 and the needling installation groove 11 is in a natural state, supporting the support block 13 and the needling assembly 4. The upper end of the needling assembly 4 protrudes from the needling installation groove 11. When the needling assembly 4 needs to be replaced, the needling assembly 4 can be taken out of the needling installation groove 11 by removing the pressing plate 5, which is convenient for replacement. Furthermore, a first reset spring pad 7 is provided at the bottom of the upper mold base 1, and the thickness of the first reset spring pad 7 is greater than or equal to the length of the steel needle 41 extending out of the lower mold base 2. Through the setting of the first reset spring pad 7, when the upper mold base 1 is pressed downward toward the lower mold base 2, the first reset spring pad 7 is squeezed and deformed, and the steel needle 41 extends from the first reset spring pad 7 to perform a needle-piercing operation on the light sheet or cardboard. When the upper mold base 1 moves upward, the first reset spring pad 7 restores its shape, hides the steel needle 41 in the first reset spring pad 7, and protects the steel needle 41. Furthermore, the acupuncture assembly 4 also includes a fixed block 42 fixed to the steel needle 41, a convex rib 111 is provided on the side wall of the acupuncture installation groove 11, and a first slide groove 421 is provided on the fixed block 42 to cooperate with the convex rib 111. In this way, the fixed block 42 is located on the upper side of the support block 13, and the convex rib 111 on the fixed block 42 cooperates with the first slide groove 421, which can not only limit the installation of the fixed block 42, that is, it can facilitate the steel needle 41 to pass through the through hole and the through hole 12, but also guide the fixed block 42 to ensure the stability of the steel needle when it moves up and down, and avoid damage to the steel needle 41 during the installation process. Furthermore, a second slide groove 131 is provided on the side wall of the support block 13 to cooperate with the convex rib 111, and similarly, the stability of the support block 13 when it moves up and down is ensured.

[0024] The upper die base 1 is movably provided with a pressure plate 5 located on the upper side of the acupuncture component 4, and the pressure plate 5 is used to apply pressure to the upper end of the acupuncture component 4. A screw rod 6 extending upward is fixed on the upper die base 1, and a connecting hole 51 cooperating with the screw rod 6 is provided on the pressure plate 5. The screw rod 6 is sleeved with a plurality of adjustment gaskets 61 located below the pressure plate 5 and a locking nut 62 located above the pressure plate 5, wherein the adjustment gasket 61 can be set to a circular ring shape or a U-shaped opening shape. Preferably, a U-shaped opening gasket is used in this embodiment, and the adjustment gasket 61 can be inserted into the screw rod 6 through the opening, without completely removing the pressure plate 5, so as to facilitate the adjustment of the downward pressing distance of the pressure plate 5. When the pressing plate 5 is pressed downward under the action of external force, it drives all the acupuncture components 4 to move downward synchronously in the acupuncture installation groove 11, and the fixed block 42 of the acupuncture component 4 drives the support block 13 to move downward to squeeze the compression elastic member 14. At this time, the compression elastic member 14 is in a compressed state. During the downward movement of the acupuncture component 4, the length of the steel needle 41 extending out of the bottom of the upper mold base 1 becomes longer, until the pressing plate 5 moves to abut against the adjusting gasket 61 and cannot move further downward, reaching the required length of the steel needle 41 extending out of the bottom of the upper mold base 1; then, through the cooperation of the locking nut 62 and the screw 6, the locking nut 62 is tightened on the top of the pressing plate 5 to fix the position of the pressing plate 5, ensuring that the length of the steel needle 41 of the acupuncture component 4 extending out of the bottom of the upper mold base 1 remains unchanged, and the acupuncture component 4 is limited. Furthermore, the upper die base 1 is provided with a baffle 15 , the baffle 15 is provided with a notch 151 , the outer edge of the pressing plate 5 is provided with a protrusion 52 corresponding to the notch 151 and extending to the outside of the baffle 15 , and the connecting hole 51 is provided on the protrusion 52 .

[0025] The lower die base 2 is provided with a lining plate 21 , and the lining plate 21 is provided with a pinhole corresponding to the steel needle 41 . The lining plate 21 is used for placing cardboard or light sheet, and the pinhole is used for cooperating with the steel needle 41 .

[0026] See also Figure 3 The utility model also provides a second embodiment of the acupuncture mold for a boneless flower lantern.

[0027] In the first embodiment, a first reset spring pad 7 is provided at the bottom of the upper mold base 1 to protect the steel needle 41 extending out of the bottom of the upper mold base 1. However, since the length of the steel needle 41 extending out of the bottom of the upper mold base 1 is adjustable, and the thickness of the first reset spring pad 7 is usually fixed, when the steel needle 41 extends out too long, it is difficult to protect the steel needle 41. When the steel needle 41 extends out too short, it is difficult for the steel needle 41 to be exposed from the first reset spring pad 7 during acupuncture, which is inconvenient for the acupuncture operation.

[0028] The difference between this embodiment and the first embodiment is that a push plate 8 is provided at the bottom of the upper die seat 1, and a through hole 81 corresponding to the steel needle 41 is provided on the push plate 8. The push plate 8 is connected to the upper die seat 1 through a reset elastic member 82. Preferably, the reset elastic member 82 is a tension spring. At this time, even if the thickness of the push plate 8 is fixed, the spring is in a natural state, and the push plate 8 is located at the lowest end. At this time, the distance between the push plate 8 and the bottom of the upper die seat 1 is large, which can accommodate the extended distance of the steel needle 41 of a longer length, thereby protecting the steel needle 41. When the upper die seat 1 is pressed down, the push plate 8 is pressed down accordingly, and when it moves to abut against the lower die seat 2, the reset elastic member 82 is compressed, and the distance between the push plate 8 and the bottom of the upper die seat 1 is reduced, until the push plate 8 abuts against the bottom of the upper die seat 1, and the bottom of the steel needle 41 passes through the through hole 81 on the push plate 8 to perform a needle-punching operation on the light sheet or cardboard. Furthermore, the push plate 8 is provided with a plurality of guide rods 83, the bottom of the upper die seat 1 is provided with a guide groove 16 corresponding to the guide rod 83, the top end of the reset elastic member 82 is fixed to the guide groove 16, and the bottom end is fixed to the push plate 8. In this way, the guide rod 83 cooperates with the guide groove 16, thereby improving the stability of the push plate 8 when it moves relative to the upper die seat 1. Furthermore, the bottom of the push plate 8 is provided with a second reset spring pad 84, which is used to flexibly contact with the light sheet or paperboard to avoid crushing the light sheet or paperboard.

[0029] When in use, the acupuncture component 4 is placed on the support block 13, and the steel needle 41 of the acupuncture component 4 extends through the through hole 12 to the lower side of the bottom of the upper mold base 1. According to the length of the steel needle that needs to extend out of the bottom of the upper mold base 1, the number of adjusting gaskets 61 is selected to be sleeved or clamped on the screw 6 to limit the downward pressing distance of the pressing plate 5, and then the protrusion 52 of the pressing plate 5 is pressed down after corresponding to the notch 151. The pressing plate 5 is pressed tightly on the top of the fixed block 42 of the acupuncture component 4, and the fixed block 42 drives the support block 13 to move downward to squeeze the compression elastic member 14. The compression elastic member 14 is in a compressed state until the pressing plate 5 abuts against the adjusting gasket 61. When the pressing plate 5 cannot move downward, the locking nut 62 is tightened on the screw 6 to complete the installation of the acupuncture component 4, and the length of the steel needle 41 extending out of the upper mold base 1 can be adjusted, and the extension lengths of multiple steel needles 41 can be ensured to be consistent. When the steel needle 41 needs to be replaced, remove the locking nut 62, take out the pressure plate 5, and the support block 13 moves upward under the resetting action of the compression elastic member 14, driving the fixed block 42 to move up and protrude from the acupuncture installation groove 11, making it convenient for the operator to take the fixed block 42 and take the acupuncture assembly 4 out of the acupuncture installation groove 11.
