Description

Technical Field

[0001] This utility model relates to the field of hot stamping mold technology, and in particular to a hot stamping and embossing composite mold for high-end packaging boxes. Background Technology

[0002] In the field of premium packaging, hot stamping and embossing are key surface decoration processes that enhance the visual quality and grade of packaging boxes. Hot stamping transfers electroplated aluminum foil to the surface of the packaging box through a heated metal printing plate to form shiny graphic logos. Embossing, on the other hand, uses the pressing action of convex and concave dies to create a three-dimensional relief effect on the surface of the packaging box. As consumers continue to demand higher aesthetics and quality from packaging, the market demand for composite processing molds that combine hot stamping and embossing functions is growing.

[0003] Different sizes and patterns of premium packaging boxes require different convex and concave inserts. However, existing mold inserts are mostly fixed directly to the template mounting slots using bolts and other fasteners. When replacing inserts, operators need to use tools to disassemble the bolts one by one, and then tighten them again after replacement. The whole process is time-consuming, which seriously affects production efficiency. Furthermore, during the hot stamping and embossing process, impurities such as aluminum foil debris and dust from the packaging box substrate can easily adhere to the surface of the convex inserts. If not cleaned in time, these impurities can cause quality problems such as incomplete graphics, uneven hot stamping, or unclear embossing in the subsequent processed packaging boxes, thus greatly reducing the hot stamping effect.

[0004] Therefore, a hot stamping and embossing composite mold for high-end packaging boxes is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a hot stamping and embossing composite mold for high-end packaging boxes. This mold solves the problem that existing molds often use bolts or other fasteners to directly fix the inserts in the mounting groove of the template. When replacing the inserts, operators need to use tools to remove the bolts one by one, and then tighten them again after replacement. The whole process is time-consuming, which seriously affects production efficiency. Furthermore, during the hot stamping and embossing process, impurities such as aluminum foil debris and dust from the packaging box substrate can easily adhere to the surface of the convex inserts. If these impurities are not cleaned in time, they can cause quality problems such as incomplete graphics, uneven hot stamping, or unclear embossing in the subsequent processed packaging boxes, thus greatly reducing the hot stamping effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hot stamping and embossing composite mold for premium packaging boxes, comprising a mounting frame, wherein an upper template and a lower template are respectively provided inside the mounting frame, and mounting grooves are provided on opposite sides of the upper and lower templates, wherein convex inserts and concave inserts are respectively provided inside the mounting grooves, and quick-release components are provided on both sides of the upper and lower templates, and a cleaning component is provided inside the mounting frame, wherein the quick-release component includes a fixing frame, the fixing frame being fixedly connected to both sides of the upper and lower templates, wherein multiple positioning rods penetrate through the fixing frame and extend into the mounting grooves, wherein a connecting block is fixedly connected to one end of the positioning rod located inside the fixing frame, and a fastening tension spring is sleeved on the surface of the positioning rod, and both ends of the fastening tension spring are fixedly connected to the connecting block and the inner wall of the mounting frame, respectively, wherein positioning grooves are provided on both sides of the convex inserts and concave inserts, and the positioning grooves are used in conjunction with the positioning rods.

[0017] 1. This application, by setting up a quick-release component, allows operators to easily remove convex or concave inserts when it is necessary to replace them. This is achieved by pulling the handle, which in turn causes the positioning rod to compress the fastening spring and exit the positioning slot via the linkage plate. When installing a new convex or concave insert, releasing the handle causes the elastic force of the fastening spring to push the positioning rod to automatically insert into the positioning slot and complete the fixation. The entire process requires no tools, significantly shortening the insert replacement time and effectively improving production efficiency.

[0018] 2. This application, by setting up a cleaning component, uses a drive motor to rotate a screw, causing the threaded block to move the support frame laterally. Simultaneously, a micro motor drives a cleaning roller to rotate, and a flexible brush thoroughly cleans the surface of the convex insert. Impurities generated during cleaning fall into a collection box, enabling automatic cleaning of the convex insert surface. This ensures the cleanliness of the convex insert surface, effectively preventing quality problems such as incomplete graphics and uneven hot stamping caused by impurities, thereby improving the product quality of hot stamping and embossing processing.

[0029] Specifically, such as Figure 4 As shown, the cleaning component 8 includes a support frame 801, which is disposed inside the mounting frame 1. A bracket 802 is fixedly connected to the top of the support frame 801, and a U-shaped frame 803 is fixedly connected to the top of the bracket 802. A cleaning roller 804 is rotatably connected inside the U-shaped frame 803 via a bearing, and the surface of the cleaning roller 804 is set as a flexible brush. The cleaning roller 804 is used in conjunction with the convex insert 5.

[0030] Specifically, such as Figure 4 As shown, a micro motor 805 is fixedly installed on the outside of the U-shaped frame 803. The output shaft of the micro motor 805 passes through the U-shaped frame 803 and is fixedly connected to the cleaning roller 804.

[0031] Specifically, such as Figure 4 As shown, a collection box 806 is provided inside the support frame 801. Alignment blocks 9 are fixedly connected to both sides of the collection box 806. Alignment grooves 10 are provided on both sides of the inner wall of the support frame 801, and the alignment blocks 9 are slidably connected to the alignment grooves 10.

[0032] Specifically, such as Figure 4 , Figure 5 As shown, a horizontal groove 11 is provided on the rear side of the inner wall of the mounting bracket 1.

[0034] Specifically, such as Figure 4 , Figure 5As shown, a drive motor 15 is fixedly mounted on the outside of the mounting bracket 1, and the output shaft of the drive motor 15 is fixedly connected to the screw 12.

[0035] In this embodiment: by setting up the cleaning component 8, the support frame 801 serves as the mounting base for the cleaning component 8 and is located inside the mounting frame 1. It provides a stable mounting platform for components such as the bracket 802 and the collection box 806. Simultaneously, through its connection with the threaded block 13, it enables the entire cleaning component 8 to move laterally, ensuring the cleaning operation covers the entire area. The bracket 802 acts as a connecting support, stably supporting the U-shaped frame 803 and the cleaning roller 804 at a height compatible with the convex insert 5, ensuring that the cleaning roller 804 can accurately contact the surface of the convex insert 5 for cleaning operations. The U-shaped frame 803 can support the cleaning roller... 804 provides rotational mounting space and support, while its structural design facilitates the installation and fixation of the micro motor 805, ensuring the stability of the cleaning roller 804 during rotation. The surface of the cleaning roller 804 is equipped with a flexible brush, which can be used in conjunction with the convex insert 5. By rotating, it cleans the surface of the convex insert 5 of electroplated aluminum foil debris, dust, and other impurities. The flexible brush ensures cleaning effectiveness while avoiding scratching the surface of the convex insert 5. The micro motor 805 provides the power source for the rotation of the cleaning roller 804, driving it to rotate at high speed to achieve efficient cleaning of impurities.

The transverse groove 11 provides installation space for the screw 12, limit rod 14, and threaded block 13, limiting the lateral movement path of the cleaning component 8 and ensuring the accuracy of its movement direction. The screw 12 can rotate under the drive of the drive motor 15, converting the rotational motion into the linear motion of the threaded block 13, thereby driving the support... The support frame 801 and the entire cleaning assembly 8 move laterally along the transverse groove 11; the threaded block 13 can drive the support frame 801 to move laterally under the drive of the screw 12, and is a transmission component connecting the screw 12 and the support frame 801; the limiting rod 14 can guide and limit the movement of the threaded block 13, preventing the threaded block 13 from rotating with the screw 12, and ensuring that the threaded block 13 drives the support frame 801 to move smoothly in a straight line; the drive motor 15 can provide power for the rotation of the screw 12, and by controlling the forward and reverse rotation of the drive motor 15, the reciprocating lateral movement of the cleaning assembly 8 can be realized, completing the comprehensive cleaning of the surface of the convex insert 5.

[0036] Specifically, such as Figure 3 As shown, the positioning rod 702 is fixedly connected to a linkage plate 16 at one end located outside the fixed frame 701, and a handle 17 is fixedly connected to the surface of the linkage plate 16.

[0037] Specifically, such as Figure 2 As shown, a hydraulic device 18 is fixedly installed on the top of the mounting frame 1. The telescopic end of the hydraulic device 18 passes through the mounting frame 1 and is fixedly connected to the upper template 2.

[0038] Specifically, such as Figure 2 As shown, a heating tube is fixedly installed inside the upper template 2, and the heating tube is used in conjunction with the convex insert 5.

[0039] In this embodiment: Through the above settings, the linkage plate 16 can connect multiple positioning rods 702 on the same side into a whole, allowing the operator to move all positioning rods 702 synchronously with one operation, simplifying the operation steps; the handle 17 can provide the operator with a force point, making it convenient to pull the linkage plate 16 to move the positioning rods 702, making the disassembly of the insert more labor-saving and convenient; the hydraulic device 18 can provide power for the lifting and lowering of the upper template 2, and by controlling the extension and retraction of the telescopic end, the pressing distance and pressure between the upper template 2 and the lower template 3 can be precisely adjusted to ensure the forming effect of hot stamping and embossing; the heating tube is fixedly installed inside the upper template 2 and can be used in conjunction with the convex insert 5, providing a stable heating source for the convex insert 5, so that the convex insert 5 reaches the temperature required for the hot stamping process, ensuring that the electroplated aluminum foil can be smoothly transferred to the surface of the packaging box, achieving a high-quality hot stamping effect.

[0040] Working principle: When it is necessary to replace the convex insert 5 or the concave insert 6, first pull the handles 17 on both sides of the upper template 2 or the lower template 3 to disengage the positioning rod 702. Then, place the convex insert 5 and the concave insert 6 into the mounting slots 4 of the upper template 2 and the lower template 3 respectively. Then, release the handles 17. The positioning rod 702 will automatically engage with the positioning slots 705 of the convex insert 5 and the concave insert 6 under the action of the fastening spring 704, completing the quick fixation. Then, start the heating tube to preheat the convex insert 5 to the set temperature. After that, accurately feed the packaging box paper or cardboard to be processed above the concave insert 6 and start the hydraulic device 18. The hydraulic device 18 drives the upper template 2 to press down, and the heated convex insert 5 will close with the concave insert 6, completing hot stamping and embossing at the same time. When it is necessary to clean the residual impurities on the surface of the convex insert 5, the drive motor 15 is started. The drive motor 15 will drive the entire cleaning assembly 8 to move through the screw 12. At the same time, the micro motor 805 is started, which drives the cleaning roller 804 to rotate at high speed. Then, the rotating brush roller will move along the surface of the convex insert 5, thereby sweeping the dust and debris into the collection box 806 below. When the collection box 806 collects too much impurity, the collection box 806 is pulled out, the impurities inside are poured out, and then it is put back in its original position.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
