Description

Technical Field

[0001] This utility model relates to the field of engraving copper mold technology, specifically a novel concave-convex engraving copper mold. Background Technology

[0002] Embossing and debossing copper molds are specialized molds used for processes such as hot pressing, hot stamping, and embossing. They create surfaces with recessed and raised patterns through fine engraving on copper materials. These molds can accurately transfer designed patterns or text onto various substrates such as paper, leather, plastic, and fabric, and are widely used in printing, packaging, decoration, and handicrafts manufacturing.

[0003] Based on the above, the inventors have discovered the following problems: Current engraving copper molds usually only have the function of embossing. During the embossing process, the substrate deforms significantly, and the substrate is prone to displacement, resulting in pattern shift and deformation, which is inconvenient to use.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a new type of concave and convex engraving copper mold in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of concave-convex engraving copper mold to solve the problems mentioned in the background art.

[0006] A novel embossed copper mold includes an installation assembly. The installation assembly has a replacement copper mold at its bottom, and positioning components at both ends of the installation assembly and on both sides of the replacement copper mold. The installation assembly includes an installation block with an installation groove at its bottom center. First hinge seats are fixedly installed at both ends of the installation block. The replacement copper mold includes a module disposed inside the installation groove, with second hinge seats fixedly installed on both sides of the module. The positioning components include positioning blocks with hinge members fixedly installed at both ends of the top of the positioning blocks. A hinge rod is inserted inside the hinge member, and the other end of the hinge rod is hinged to the first and second hinge seats. A torsion spring is sleeved on the outer side of the middle portion of the hinge rod.

[0007] By adopting the above technical solution, the first hinge seat facilitates the fixed connection between the positioning component and the installation component. The module is set inside the installation slot, facilitating the convenient fixed connection between the replacement copper mold and the installation component. The second hinge seat facilitates the fixed connection between the positioning component and the replacement copper mold. Hinges are fixedly installed at both ends of the top of the positioning block, and hinge rods are inserted inside the hinges to facilitate the hinge connection between the positioning block, the installation block, and the module. A torsion spring is sleeved on the outer side of the middle of the hinge rod, which provides elastic force to make the positioning block flip downward. When the installation component drives the replacement copper mold to hot stamp the substrate, the elastic force provided by the torsion spring makes the positioning block press firmly against the substrate, preventing the substrate from shifting during the hot stamping process.

[0008] Furthermore, the bottom of the positioning block is arc-shaped, and an anti-slip plate is fixedly installed on the bottom of the positioning block.

[0009] By adopting the above technical solution, the bottom of the positioning block is arc-shaped and an anti-slip plate is fixedly installed on the bottom of the positioning block. The anti-slip plate increases the friction between the positioning block and the substrate. During the pressing process, the arc-shaped positioning block will stretch the substrate outward, making the surface of the substrate flat and improving the hot stamping effect.

[0010] Furthermore, the module is made of beryllium bronze, and the bottom of the module has grooves and protrusions.

[0011] By adopting the above technical solution, with grooves and protrusions at the bottom of the module, beryllium bronze has extremely high hardness and strength. Its relatively thin size can maintain good physical properties in high-temperature environments, and it helps to improve heating efficiency and uniformly transfer heat. The grooves make the parts that need to be protruded appear as raised in the finished product, and the protrusions make the patterned parts in the finished product appear as recessed.

[0012] Furthermore, a heating groove is provided on the top of the module, the heating groove has a rectangular structure, and a fixing screw is fixedly installed at the center of the top of the module.

[0013] By adopting the above technical solution, the setting of heating groove and fixing screw facilitates the fixed connection between the replacement copper mold and the mounting component, and facilitates the heating of the replacement copper mold, thereby facilitating hot stamping.

[0014] Furthermore, mounting screws are fixedly installed at the four corners of the top of the mounting block, and heating electrodes are provided at both ends of the top of the mounting block.

[0015] By adopting the above technical solution, and by installing the screw and heating electrode, it is easy to fix and electrically connect the device to the output end of an external hot stamping machine, which facilitates the device to hot stamp the substrate and to supply power to the heating coil.

[0016] Furthermore, a gear cavity is provided inside the top of the mounting block, and a fixed gear is rotatably connected to the middle of the inner side of the gear cavity.

[0017] By adopting the above technical solution, a fixed gear is rotatably connected to the middle of the inner side of the gear cavity, which facilitates the installation space for the fixed gear and makes it easy for the fixed gear to rotate.

[0018] Furthermore, a threaded sleeve is fixedly installed in the middle of the fixed gear, and a fixing hole is opened in the middle of the top of the mounting groove. The fixing hole is sleeved on the outside of the fixing screw, and the threaded sleeve is threadedly connected to the fixing screw.

[0019] By adopting the above technical solution, the screw sleeve is threadedly connected to the fixing screw, which facilitates the rotation of the fixing gear to fix the module inside the mounting slot.

[0020] Furthermore, a knob is rotatably connected to both ends inside the gear cavity. One side of the knob is located on the outside of the mounting block, and a toothed groove is formed in the middle of the outer side of the knob. The toothed groove meshes with the fixed gear.

[0021] By adopting the above technical solution, the gear teeth mesh with the fixed gear, making it easy to control the rotation of the fixed gear by turning the knob.

[0022] Furthermore, a heating coil is fixedly installed at the top of the inner side of the mounting groove. The heating coil is located inside the heating groove and is electrically connected to the heating electrode.

[0023] By adopting the above technical solution, a heating coil is set inside the heating tank and electrically connected to the heating electrode, which facilitates the heating coil to heat the module, thereby realizing hot stamping on the substrate.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows: the first hinge seat facilitates the fixed connection between the positioning component and the installation component; the module is set inside the installation groove, facilitating the convenient fixed connection between the replacement copper mold and the installation component; the second hinge seat facilitates the fixed connection between the positioning component and the replacement copper mold; hinge members are fixedly installed at both ends of the top of the positioning block, and a hinge rod is inserted inside the hinge member, facilitating the hinge connection between the positioning block, the installation block, and the module; a torsion spring is sleeved on the outer side of the middle of the hinge rod, facilitating the torsion spring to provide elastic force to make the positioning block flip downwards; when the installation component drives the replacement copper mold to hot stamp the substrate, the elastic force provided by the torsion spring makes the positioning block press firmly against the substrate, preventing the substrate from shifting during the hot stamping process.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-5This utility model provides a technical solution: a novel concave-convex engraving copper mold, including a mounting component 101, a replacement copper mold 102 at the bottom of the mounting component 101, positioning components 103 at both ends of the mounting component 101 and both sides of the replacement copper mold 102, the mounting component 101 including a mounting block 10101, a mounting groove 10103 in the middle of the bottom end of the mounting block 10101, and first hinge seats 10102 fixedly mounted at both ends of the mounting block 10101. The first hinge seats 10102 facilitate... The positioning component 103 is fixedly connected to the mounting component 101. The replacement copper mold 102 includes a module 10201, which is disposed inside the mounting groove 10103. The module 10201 facilitates the convenient and easy fixed connection between the replacement copper mold 102 and the mounting component 101. Second hinge seats 10202 are fixedly mounted on both sides of the module 10201. The second hinge seats 10202 facilitate the connection between the positioning component 103 and the replacement copper mold 102. For fixed connection, the positioning component 103 includes a positioning block 10301. Hinges 10302 are fixedly installed at both ends of the top of the positioning block 10301. A hinge rod 10303 is inserted inside the hinge 10302. The fixed installation of hinges 10302 at both ends of the top of the positioning block 10301 and the insertion of the hinge rod 10303 facilitates hinged connection between the positioning block 10301 and the mounting block 10101 and the module 10201. The other end of the hinge rod 10303 is connected to the... A hinge seat 10102 and a second hinge seat 10202 are hinged together, and a torsion spring 10304 is sleeved on the outer side of the middle part of the hinge rod 10303. The torsion spring 10304 provides elastic force to make the positioning block 10301 flip downward. When the mounting assembly 101 drives the replacement copper mold 102 to hot stamp the substrate, the elastic force provided by the torsion spring 10304 makes the positioning block 10301 press firmly on the substrate to prevent the substrate from shifting during the hot stamping process.

[0033] The positioning block 10301 has a rounded bottom and an anti-slip plate 10305 is fixedly installed on its bottom. The rounded bottom and the anti-slip plate 10305 increase the friction between the positioning block 10301 and the substrate. During the pressing process, the rounded positioning block 10301 will stretch the substrate outward, making the surface of the substrate flat and improving the hot stamping effect.

[0034] The module 10201 is made of beryllium bronze, and the bottom of the module 10201 is provided with a groove 10203 and a protrusion 10204. The groove 10203 and the protrusion 10204 at the bottom of the module 10201 are provided because beryllium bronze has extremely high hardness and strength. Its relatively thin size can maintain good physical properties in high temperature environments, and it helps to improve heating efficiency and uniformly transfer heat. The groove 10203 makes the parts that need to be protruded appear as raised in the finished product, and the protrusion 10204 makes the patterned parts in the finished product appear as recessed.

[0035] The module 10201 has a heating groove 10205 on its top. The heating groove 10205 has a rectangular structure. A fixing screw 10206 is fixedly installed in the middle of the top of the module 10201. The setting of the heating groove 10205 and the fixing screw 10206 makes it easy to fix the replacement copper mold 102 to the mounting component 101, and also makes it easy to heat the replacement copper mold 102, thereby facilitating hot stamping.

[0036] The mounting block 10101 has mounting screws 10107 fixedly installed at the four corners of its top, and heating electrodes 10112 are provided at both ends of its top. The mounting screws 10107 and heating electrodes 10112 facilitate the fixed connection and electrical connection between the device and the output end of the external hot stamping machine, making it convenient to drive the device to hot stamp the substrate and provide power to the heating coil 10105.

[0037] The mounting block 10101 has a gear cavity 10106 inside its top end. A fixed gear 10110 is rotatably connected to the middle of the inner side of the gear cavity 10106. The fixed gear 10110 is rotatably connected to the middle of the inner side of the gear cavity 10106, which provides installation space for the fixed gear 10110 and facilitates the rotation of the fixed gear 10110.

[0038] The fixed gear 10110 has a screw sleeve 10111 fixedly installed in the middle. The mounting groove 10103 has a fixing hole 10104 in the middle of the top. The fixing hole 10104 is sleeved on the outside of the fixing screw 10206. The screw sleeve 10111 is threadedly connected to the fixing screw 10206. The screw sleeve 10111 is threadedly connected to the fixing screw 10206, which makes it easy to rotate the fixed gear 10110 to fix the module 10201 inside the mounting groove 10103.

[0039] The gear cavity 10106 has a knob 10108 rotatably connected to both ends inside. One side of the knob 10108 is located on the outside of the mounting block 10101. A toothed groove 10109 is provided in the middle of the outer side of the knob 10108. The toothed groove 10109 is meshed with the fixed gear 10110. The meshing connection between the toothed groove 10109 and the fixed gear 10110 makes it easy to rotate the knob 10108 to control the rotation of the fixed gear 10110.

[0040] A heating coil 10105 is fixedly installed at the top of the inner side of the mounting groove 10103. The heating coil 10105 is located inside the heating groove 10205 and is electrically connected to the heating electrode 10112. The heating coil 10105 is located inside the heating groove 10205 and is electrically connected to the heating electrode 10112, which facilitates the operation of the heating coil 10105 to heat the module 10201, thereby realizing hot stamping on the substrate.

[0041] Specifically, the working principle of this novel embossed copper mold is as follows: During use, the mounting screw 10107 and heating electrode 10112 facilitate fixed and electrical connection between the device and the output of an external hot stamping machine. This allows the device to easily heat the substrate and power the heating coil 10105. The toothed groove 10109 meshes with the fixed gear 10110, allowing the knob 10108 to control the rotation of the fixed gear 10110. The threaded sleeve 10111 is threadedly connected to the fixed screw 10206, facilitating the rotation of the fixed gear 10110 to fix the module 10201 onto the mounting plate. Inside the mounting groove 10103, a heating coil 10105 is installed inside the heating groove 10205, and the heating coil 10105 is electrically connected to the heating electrode 10112. This allows the heating coil 10105 to heat the module 10201, thereby achieving hot stamping on the substrate. The bottom of the module 10201 has a groove 10203 and a protrusion 10204. Beryllium bronze has extremely high hardness and strength, and its relatively thin dimensions maintain good physical properties even at high temperatures, which helps to improve heating efficiency and uniformly transfer heat. The groove 10203 makes the parts that need to protrude appear as protrusions in the finished product. The protrusion 10204 creates a recessed effect for the patterned portion of the finished product. The module 10201 is positioned inside the mounting groove 10103, facilitating easy and convenient connection of the replacement copper mold 102 to the mounting assembly 101. Hinges 10302 are fixedly mounted at both ends of the top of the positioning block 10301. A hinge rod 10303 is inserted inside the hinge 10302, allowing the positioning block 10301 to be hinged to the mounting block 10101 and the module 10201. A torsion spring 10304 is sleeved on the outer side of the middle of the hinge rod 10303, providing elasticity to keep the positioning block 10201 in place. When 0301 is flipped downwards, the spring force provided by the torsion spring 10304 when the mounting component 101 drives the replacement copper mold 102 to hot stamp the substrate causes the positioning block 10301 to press the substrate tightly, preventing the substrate from shifting during the hot stamping process. The bottom of the positioning block 10301 is arc-shaped, and an anti-slip plate 10305 is fixedly installed on the bottom of the positioning block 10301. The anti-slip plate 10305 increases the friction between the positioning block 10301 and the substrate. During the pressing process, the arc-shaped positioning block 10301 will stretch the substrate outwards, making the surface of the substrate flat and improving the hot stamping effect.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
