[0002] Hot stamping embossing die is a tool used in the printing and packaging industry. It combines hot stamping technology and embossing technology. Through the principle of heat transfer, it forms a special metal effect on the surface of the substrate and achieves a three-dimensional relief effect. This mold has the characteristics of high precision, strong anti-prevention rate and long service life, and can hot stamp out beautiful and elegant product effects. After searching, the existing technology (Announcement No.: CN202221288105.8) is a replaceable hot stamping mold head of a hot stamping machine. The article records that "when installing the hot stamping mold head, the hot stamping mold head is inserted into the installation slot, and then the screw is rotated. Due to the sliding connection between the slider and the slide slot, the pressure plate can be stably driven to move, and the pressure plates on the left and right sides are close to each other to clamp the hot stamping mold head. The pressure plate is located on the lower side of the shoulder block, and the thrust applied to the hot stamping mold head by the spring is further improved to further improve the stability of the hot stamping mold head after installation. When the hot stamping mold head is inserted, the screw is rotated to make the pressure plate away from the hot stamping mold head, and the hot stamping mold head can be removed. Therefore, the hot stamping mold head of the utility model is easy to replace and the work efficiency is improved." However, in the existing technology, it is difficult to ensure that the hot stamping mold head is aligned with the convex bottom mold below when the pressure plate clamps the hot stamping mold head on the left and right sides.

[0018] Reference Figures 1 to 4 As shown, the utility model provides a quick-change hot stamping embossing mold, comprising: an embossing lower mold body 1, a hot stamping upper mold body 2 and a hydraulic plate 3. The upper end of the embossing lower mold body 1 is correspondingly distributed with the hot stamping upper mold body 2, and the upper end of the hot stamping upper mold body 2 is attached with the hydraulic plate 3.

[0019] Fixed blocks 12 are welded on the left and right sides of the lower embossing mold body 1, and the inner side of the fixed block 12 is movably connected to the positioning column 11 through the hinge block 13. Positioning groove blocks 22 are provided on the left and right sides of the hot stamping upper mold body 2. The left and right sides of the hydraulic plate 3 are connected to the adjusting block 51 through the electric push rod 31. The side end of the adjusting block 51 is connected to the L-shaped pressure plate 5 through the adjusting screw 52. The left and right sides of the lower embossing mold body 1 are clamped with a splint 42, and the lower end of the splint 42 is connected to the mold mounting table 4 through a screw nut 43.

[0020] When it is necessary to replace the hot stamping embossing mold at the mold mounting table 4 and the hydraulic plate 3, move the L-shaped pressing plate 5 and the splint 42 to the outer end, take out the embossing lower mold body 1 and the hot stamping upper mold body 2, and then place another set of embossing lower mold bodies 1 on the surface of the mold mounting table 4, move the side end positioning column 11 of the replaced lower embossing mold body 1 to a vertical state, and insert the other set of hot stamping upper mold bodies 2 above the replaced lower embossing mold body 1 through the positioning column 11. At this time, move the hydraulic plate 3 downward so that the hydraulic plate 3 fits with the fixed top plate 21 of the replaced hot stamping upper mold body 2. At this time, the motor 44 drives the splint 42 to clamp the replaced lower embossing mold body 1, and then rotate the adjusting screw 52 and move the L-shaped pressing plate 5 upward so that the L-shaped pressing plate 5 is pressed on the left and right sides of the hot stamping upper mold body 2 to complete the installation of the replaced hot stamping embossing mold.

[0021] In this embodiment, a hydraulic cylinder 32 is connected to the upper surface of the hydraulic plate 3. Electric push rods 31 are fixed to the left and right extended surfaces of the hydraulic plate 3. A heat conducting plate 34 is welded to the lower surface of the hydraulic plate 3. A heater 33 is mounted on the upper end surface of the heat conducting plate 34. The lower end surface of the heat conducting plate 34 is attached to the fixed top plate 21. The fixed top plate 21 is welded to the upper end of the hot stamping upper mold body 2.

[0022] As a preferred embodiment, the hydraulic cylinder 32 drives the installed hot stamping upper mold body 2 through the hydraulic plate 3 to perform hot stamping processing. The heat conducting plate 34 conducts the heat generated by the heater 33 to the hot stamping upper mold body 2.

[0023] In this embodiment, positioning slots 22 are symmetrically welded to the lower end of the fixed top plate 21. L-shaped pressure plates 5 are symmetrically attached to the left and right sides of the lower surface of the fixed top plate 21. Positioning slots 22 are located at the front and rear sides of the L-shaped pressure plate 5. Positioning posts 11 are inserted into the lower end grooves of positioning slots 22. The L-shaped pressure plate 5 extends through the inside of the adjustment block 51, and the mold mounting platform 4 is attached to the lower surface of the embossed lower mold body 1.

[0024] As a preferred embodiment, the positioning slots 22 are engaged with the positioning posts 11, aligning the lower embossing mold body 1 and the upper hot stamping mold body 2. This allows for clamping and installation based on the alignment of the lower embossing mold body 1 and the upper hot stamping mold body 2, ensuring accurate alignment after replacement. Rotating the adjustment screw 52 drives the L-shaped pressing plate 5 to move left and right, causing the side clamps of the L-shaped pressing plate 5 to press against the lower surface of the fixed top plate 21.

[0025] In this embodiment, two sets of screw nuts 43 are installed in the groove of the mold mounting table 4; and the two sets of screw nuts 43 are connected by a connecting rod 41, and the right end of the screw nut 43 is connected to the motor 44.

[0026] As a preferred embodiment, the two sets of screw nuts 43 are driven to rotate by the motor 44, so that the nuts on the screws convert the rotational motion into linear motion, thereby driving the clamping plate 42 to move in the opposite direction, so as to facilitate the clamping of the embossed lower mold body 1 on the surface of the mold mounting table 4.

[0027] In this embodiment, the positioning column 11, the hinge block 13, the positioning groove block 22, the clamping plate 42 and the L-shaped pressing plate 5 constitute the positioning and disassembly mechanism of the embossing lower mold body 1 and the hot stamping upper mold body 2.

[0028] As a preferred embodiment, the positioning and disassembly mechanism of the embossing lower mold body 1 and the hot stamping upper mold body 2 realizes the rapid positioning and disassembly function of the hot stamping embossing mold as a whole, conveniently and quickly replacing hot stamping embossing molds of different styles, ensuring the precise alignment of the hot stamping embossing mold after replacement, and improving the accurate mold changing effect of the hot stamping embossing mold.

[0029] The quick-mold-changing hot stamping and embossing mold of the utility model can effectively solve the problem in the existing technology that it is difficult to ensure that the hot stamping mold head is aligned with the embossing bottom mold below when the pressure plate clamps the hot stamping mold head on the left and right sides. It realizes a hot stamping and embossing mold with quick positioning and disassembly, and conveniently and quickly replaces hot stamping and embossing molds of different styles, ensuring that the hot stamping and embossing mold after replacement is accurately aligned, improving the accurate mold changing effect of the hot stamping and embossing mold, and is suitable for quick-mold-changing hot stamping and embossing molds.
