Description

Technical Field

[0001] This invention relates to the field of heating composite molds for hemp fiberboard panels, and particularly to a heating composite mold for hemp fiberboard panels. Background Technology

[0002] To enhance product quality and create a warm, comfortable, and luxurious interior atmosphere, the modern automotive industry often covers parts with fabrics or artificial leather. Traditional processes typically involve first creating the part's skeleton using plastic injection molding, and then applying the fabric or artificial leather to the skeleton's surface with adhesives to complete the final part. However, adhesive bonding can lead to the production of formaldehyde, which can negatively impact human health. In today's automotive development trend, which increasingly emphasizes lightweighting and energy conservation, hemp fiber thermoforming technology has been widely used in the processing and manufacturing of automotive interior parts. Hemp fiberboard is usually formed in a mold using a thermoforming process.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Example: refer to Figures 1 to 12A composite mold for heating fiberboard panels includes an upper template 1 and a lower template 2. An upper mold base 3 and a lower mold base 4 are fixedly mounted on the upper template 1 and lower template 2, respectively. An upper mold core 31 and a lower mold groove 42 are fixedly mounted on the upper mold base 3 and lower mold base 4 based on an upper locking device 5 and a lower locking device 6, respectively.

[0021] refer to Figure 5 and Figure 7 Specifically, the active heating device 8 includes a heating base 88 and an upper heating component 81 and a lower heating component 82 respectively fixedly connected to the heating base 88. A heat insulation plate 83 is fixedly provided between the upper heating component 81 and the lower heating component 82 in the heating base 88. The heat insulation plate 83 isolates the upper heating component 81 and the lower heating component 82, thus preventing them from affecting each other and thus the heating effect. The heating base 88 is shaped to fit the upper mold core 31 and the lower mold groove 42, which facilitates the full and uniform heating of the hemp fiberboard and fabric, and helps improve the molding quality. The upper heating component 81 includes several components evenly arranged and fixedly connected to the heat insulation plate 83 based on mounting brackets 84. The top surface has a first heating tube 85 and several second heating tubes 86 fixedly connected to the side wall of the heating base 88 based on the mounting bracket 84 and arranged around the first heating tube 85. The assembly of the first heating tube 85 and the second heating tubes 86 facilitates the full heating of the hemp fiberboard and avoids uneven heating that would affect the molding effect. The lower heating assembly 82 includes a third heating tube 87 that is evenly arranged and fixedly connected to the bottom surface of the heat insulation plate 83 based on the mounting bracket 84. The third heating tube 87 heats the surface of the fabric laid on the lower mold groove 42.

The first synchronous drive assembly 73 includes a first drive shaft 731 rotatably connected to the horizontal fixed seat 711 along the horizontal direction. The drive shaft 731 is coaxially fixed with a second horizontal bevel gear 732 that cooperates with the first horizontal bevel gear 717 at both ends. The first drive shaft 731 is coaxially fixed with a third horizontal bevel gear 733. The horizontal fixed seat 711 is fixedly connected with a horizontal drive motor 734. The output end of the horizontal drive motor 734 is coaxially fixed with a fourth horizontal bevel gear 735 that cooperates with the third horizontal bevel gear 733. After the hemp fiberboard and the panel are placed, the horizontal drive motor 734 drives the third horizontal bevel gear 733 to rotate through the fourth horizontal bevel gear 735, thereby driving the first drive shaft 731 to rotate. The first drive shaft 731 drives the first horizontal drive bevel gear to rotate through the second horizontal bevel gear 732, thereby driving the horizontal adjusting screw 715 to rotate. This causes the horizontal screw seat 716 to slide along the direction of the horizontal adjusting screw 715, thereby driving the horizontal adjusting seat 713 to slide along the direction of the horizontal adjusting slide rail 712, thus moving the active heating device 8 between the upper mold seat 3 and the lower mold seat 4.

[0024] refer to Figures 2 to 4Specifically, the vertical adjustment assembly 72 includes a vertical adjustment slide rail 721 fixedly connected to the horizontal adjustment seat 713 along the vertical direction and a vertical adjustment screw 722 rotatably connected to the horizontal adjustment seat 713 along the vertical direction.

A second synchronous drive assembly 74 for driving the vertical adjustment assembly 72 to move synchronously is fixedly provided on the horizontal adjustment seat 713. The first synchronous drive assembly 73 and the second synchronous drive assembly 74 have the same structure. The second synchronous drive assembly 74 includes a second drive shaft 741 rotatably connected to the horizontal adjustment seat 713 along the horizontal direction. The two ends of the second drive shaft 741 are coaxially fixed with a second vertical bevel gear 742 that cooperates with the first vertical bevel gear 725. A third vertical bevel gear 743 is coaxially fixed on the second drive shaft 741. A vertical drive motor 744 is fixedly connected to the horizontal adjustment seat 713. A fourth vertical bevel gear 745 that cooperates with the third vertical bevel gear 743 is coaxially fixed at the output end of the vertical drive motor 744. The vertical drive motor 744 drives the third vertical bevel gear 743 to rotate through the fourth vertical bevel gear 745, thereby driving the second drive shaft 741 to rotate. The second drive shaft 741 drives the first vertical drive bevel gear to rotate through the second vertical bevel gear 742, thereby driving the vertical adjustment screw 722 to rotate, and then driving the vertical screw seat 724 to slide along the direction of the vertical adjustment screw 722, thereby driving the active heating device 8 to move up and down to fit the upper mold core 31 or the lower mold groove 42 for separate heating.

[0025] refer to Figures 5 to 6 Specifically, the upper mold core 31 is detachably and fixedly mounted on the upper mold base 3. The upper locking device 5 includes several guide components 51 and disassembly components 52 respectively fixedly connected between the upper mold base 3 and the upper mold core 31.

The guide seat 511 has a guide hole that mates with the guide shaft 512 to ensure the accuracy of the connection between the upper mold core 31 and the upper mold base 3. The disassembly and assembly assembly 52 includes a disassembly and assembly cylinder 521 fixedly connected to the upper mold base 3 in the vertical direction and a disassembly and assembly seat 522 fixedly connected to the upper mold core 31. The telescopic end of cylinder 521 is fixedly provided with a disassembly block 523 that is engaged with the disassembly seat 522. The disassembly cylinder 521 drives the disassembly seat 522 to move, thereby realizing the separation of the upper mold core 31 from the upper mold base 3 for maintenance.

A locking hole corresponding to the locking groove is also provided on the hemp fiber board. When the hemp fiber board is placed and adhered to the upper mold core 31, the upper locking cylinder 534 drives the locking rod 533 to rotate, thereby causing the locking block 535 to engage with the locking groove and the locking hole. This allows the hemp fiberboard to be locked and fixed on the upper mold core 31. The lower locking assembly 61 includes a third locking seat 62 fixedly connected to the lower mold base 4 and a fourth locking seat 63 fixedly connected to the lower mold groove 42.
