[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 6 As shown, this utility model discloses a high-frequency device for hot-pressing a logo, comprising a high-frequency welding machine 1, an upper template 2, a pressure block 3, a lower mold block 4, a lower mold adjustment plate 5, and a lower mold fixing plate 6. The top of the upper template 2 is connected to the high-frequency welding machine 1, and the upper template 2 has a raised logo pattern 16. The pressure block 3 has a pattern clearance hole 17, and the bottom of the upper template 2 is connected to the pressure block 3, with the logo pattern 16 passing through the pattern clearance hole 17. The bottom of the lower mold fixing plate 6 is connected to the base of the high-frequency welding machine 1, and the top of the lower mold fixing plate 6 has an adjustment groove. The lower mold adjustment plate 5 is connected in the adjustment groove, and the lower mold block 4 is connected to the top of the lower mold adjustment plate 5. The pressure block 3 and the lower mold block 4 form an inner cavity for positioning the product 15. The high-frequency welding machine 1 conducts power to the upper template 2 and the lower mold block 4 respectively. During hot pressing, the logo pattern 16 of the upper template 2 contacts the product 15. The upper template 2 and the lower mold block 4 constitute the upper and lower electrodes of a high-frequency electromagnetic field.

[0023] The upper template 2 is fixed on the high-frequency welding machine 1 and serves as the upper electrode. The pressure block 3 is installed below the upper template 2, pressing down on the product 15 to fix it on the lower mold plate 4, thus better enabling the high-frequency self-excited oscillator to generate a high-frequency electromagnetic field. The lower mold block 4 forms a suitable cavity to match the product 15, fixing its position and also serving as the lower electrode. The lower mold adjustment plate 5 is used to adjust the position of the lower mold block 4, reducing processing errors of the product 15; the lower mold adjustment plate 5 is fixed below the high-frequency welding machine 1. The pattern clearance hole 17 can be designed to align with the position on the product where the logo needs to be hot-pressed. After the logo pattern 16 passes through the pattern clearance hole 17, it can just contact the corresponding logo position on the product. At this time, the upper and lower surfaces of the product 15 contact the upper template 2 and the lower mold block 4 respectively. The high-frequency welding machine 1, through the upper template 2 and the lower mold block 4 forming the upper and lower electrodes of the high-frequency electromagnetic field, performs high-frequency hot-pressing of the logo on the designated position of the product.

[0024] The principle of high frequency is that a high-frequency electromagnetic field is generated by a vacuum tube self-excited oscillator. The workpiece is pressed between the upper and lower electrodes with the high-frequency electromagnetic field. The molecules inside are excited and move at high speed, rubbing against each other and generating heat to melt. Under the pressure of the upper template 2 and the lower model block 4, the purpose of welding or embossing is achieved. High frequency is high frequency wave.

[0025] The lower mold block 4 has a flat boss 13 on its top that matches the shape of the product 15, and the product 15 is fitted onto the flat boss 13. The flat boss 13 adapts to the structure of the product 15, so that the product 15 can be accurately placed on the lower mold block 4 to align with the position of the pressure block 3, and also serves to fix the position of the product 15.

[0026] The pressure block 3 has positioning guide edges 14 on both sides. The positioning guide edges 14 match the edge shape of the product 15. During hot pressing, the positioning guide edges 14 contact the edge of the product 15. The positioning guide edges 14 play a positioning role when the pressure block 3 presses down on the product 15. By contacting the edge of the product 15, the pattern avoidance hole 16 is limited to be aligned with the position of the logo to be hot pressed on the product, ensuring the consistency of the hot pressing position of the logo on each product 15.

[0027] The high-frequency equipment for hot-pressing logos also includes an X-axis adjusting screw 7 and a Y-axis adjusting screw 8. The X-axis adjusting screw 7 passes through the lower mold fixing plate 6 in the X direction and is threadedly connected to the lower mold adjusting plate 5. The Y-axis adjusting screw 8 passes through the lower mold fixing plate 6 in the Y direction and is threadedly connected to the lower mold adjusting plate 5. By turning the X-axis adjusting screw 7, which engages with the threaded connection of the lower mold adjusting plate 5, the lower mold adjusting plate 5 can be adjusted relative to the lower mold fixing plate 6 to achieve fine-tuning in the X direction. By turning the Y-axis adjusting screw 8, which engages with the threaded connection of the lower mold adjusting plate 5, the lower mold adjusting plate 5 can be adjusted relative to the lower mold fixing plate 6 to achieve fine-tuning in the Y direction.

[0028] The high-frequency equipment for hot-pressing logos also includes adjusting shims 9, which are connected around the sides of the lower mold adjusting plate 5. Preferably, the lower mold adjusting plate 5 has adjusting shims 9 on all four sides, allowing for leveling adjustments by moving the adjusting shims 9 as needed.

[0029] The lower mold adjusting plate 5, X-axis adjusting screw 7, Y-axis adjusting screw 8, and adjusting shim 9 can finely adjust the position in the X and Y directions. Since the errors in processing and product 15 are unavoidable, the position of the lower mold adjusting plate 5 is ultimately adjustable.

[0030] The high-frequency equipment for hot-pressing logos also includes a limiting block 10 and a limiting gasket 11. The limiting block 10 is located in the space on both sides between the upper template 2 and the pressing block 3. The limiting block 10 contacts the upper template 2 and the pressing block 3 through the limiting gasket 11. The adjustable limiting block 10 and limiting gasket 11 can be finely adjusted according to the pressing depth of the logo. The fiber block is made of fiberglass board, and the limiting gasket 11 is made of stainless steel for better heat insulation and electrical insulation.

[0031] The pressure block 3 and the limiting block 10 are made of fiberglass. Using fiberglass provides better heat insulation and electrical insulation, avoiding interference with the transmission of high-frequency electromagnetic fields.

[0032] The upper template 2 is made of copper. The upper template 2 adopts a copper head structure. Copper has a high thermal conductivity, high density, and good strength.

[0033] The lower mold block 4, the lower mold adjustment plate 5, and the lower mold fixing plate 6 are all made of aluminum. Aluminum can better transfer heat and reduce the overall weight.

[0034] The high-frequency welding machine 1 is equipped with a hot-press lifting module 12, which connects the upper template 2. The hot-press lifting module 12 can move the upper template and the pressure block 3 up and down. Before placing the product 15, the hot-press lifting module 12 moves the upper template 2 and the pressure block 3 upward to make room for placement. After the product 15 is placed in place, the hot-press lifting module 12 moves the upper template and the pressure block 3 downward so that the pressure block 3 presses on the product 15 for hot pressing.

[0035] The requirement for hot-pressing logos is that the 3D texture must be flawless, such as indistinct angles, uneven surfaces, and minor defects. Conventional hot-pressing of logos typically uses a servo hot press, which utilizes the principle of heating the upper mold's copper head through a heating element, causing the machine to press downwards. This is feasible for larger fonts with less stringent requirements. However, it's more challenging for 3D logos with smaller fonts. Under high temperature and pressure, the copper head in areas with smaller fonts may gradually collapse or deform. High-frequency hot pressing has now been proven to produce a more aesthetically pleasing, virtually flawless result, creating a 3D texture comparable to the original 3D logo image. The principle of high-frequency hot pressing involves a high-frequency electromagnetic field generated by a self-excited electron tube oscillator. The workpiece is pressed between the upper and lower electrodes, creating a high-frequency electromagnetic field. The internal molecules are excited and move at high speed, rubbing against each other and generating heat, melting the material. Under the pressure of the mold, this achieves the purpose of welding or embossing. High-frequency refers to high-frequency waves. Therefore, using high-frequency equipment to create the logo's appearance has more advantages, as it offers reliable quality and is worth the price.

[0036] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
