Description

Technical Field

[0001] The invention relates to the technical field of automobile interior decoration processing, in particular to a hot pressing molding device for automobile interior decoration. Background Art

[0002] During the processing of automotive interior parts, manufacturers will cover the plastic frame of the interior with skins of different materials, and have also developed many kinds of covering processes. There is currently a hot pressing forming covering process, which requires applying glue to the joint surface of the skin and the plastic frame and then drying it. The skin and the plastic frame are then placed in a hot pressing mold, and the solid glue is melted and activated by the hot pressing mold heating system. At the same time, the upper and lower molds of the hot pressing mold are closed to apply a certain amount of pressure to achieve the purpose of firmly bonding the skin to the plastic frame. For example, the square storage box in the automotive interior parts also needs to be covered.

[0003] In the invention with publication number CN118238427A, after the interior trim panel is placed and positioned on the convex module on the lower side, the concave module on the upper side can be driven to rotate to the lower side, which is convenient for the placement and positioning of the veneer material, and accelerates the heat dissipation of the veneer material on the surface of the elastic bearing block when the mold is closed, so that the curing time of the glue on the veneer material is accelerated, thereby improving the hot pressing molding efficiency.

[0004] However, the above invention requires that the interior trim panel be placed on the convex module on the lower side first, and then the concave module is rotated and the veneer material is placed on the concave module. They must be placed in sequence, and the interior trim panel and the veneer material cannot be placed at the same time, which reduces the installation efficiency. In addition, before hot pressing, the above invention first places the veneer material in the center on the elastic support block 37, and then controls the insulation frame 13 to drive the baking lamp 14 to heat the veneer material. The glue on the upper surface of the veneer material is activated, and then the heat dissipation is accelerated by allowing the L-shaped negative suction pipe 45 to draw. When the veneer material is heated by the baking lamp 14, the elastic support block 37 and the entire concave module are heated, so that during subsequent cooling, the entire concave module and the veneer material need to be cooled together, thereby reducing the overall cooling efficiency.

Extension grooves 108 are provided on two opposite sides of the fixed sleeve rod 106, and one side of the extension groove 108 is located in the first lower mold 5 and has an extrusion surface 109, fixed blocks 107 are movably inserted on two opposite sides of the bottom end of the fixed sleeve rod 106, and a fourth spring 1015 is fixedly connected between the side wall of the fixed block 107 and the fixed sleeve rod 106.

[0022] Specifically, the suction holes 1019 suck up the veneer material located at the upper end of the side wall of the storage box to prevent the veneer material from being taken out of the first lower mold 5. The inner cavity of the first lower mold 5 will produce downward friction on the veneer material, thereby causing the veneer material to separate from the storage box.

[0023] Through the cooperation of the vertical moving mechanism 7 and the transfer mechanism 10, the veneer material is kept away from the heated first lower mold 5 during subsequent cooling, thereby further improving the cooling efficiency. At the same time, through the action of the transfer mechanism 10, the veneer material is kept in close contact with the storage box during the transfer process.

[0024] The suction of the vacuum pump can be used to absorb the storage box, and the wrapped storage box can be conveniently cooled. At the same time, the position of the movable frame 105 can be automatically locked and unlocked by suction, so that it is convenient for disassembly and assembly.

[0025] Working principle: when in use, first start the motor 2 to move the sleeve plate 73 upwards, then place the storage box and the veneer material on the upper end of the first lower mold 5 and the second lower mold 8 respectively, when the storage box opening is placed upwards on the upper surface of the placement plate 11 in the second lower mold 8, the positioning block 13 in the second lower mold 8 will abut against the side wall of the storage box, so that the storage box is positioned, and the second lower mold 8 is subjected to the upward elastic force of the fifth spring 12, which will make the storage box located on the upper side of the inner cavity of the second lower mold 8, and then the motor 2 is rotated counterclockwise, and after the upper end of the sliding rod 72 abuts against the end of the fixing rod 71 close to the second lower mold 8, the sleeve plate 73 moves vertically downward, so that the bottom end of the upper mold 91 is in close contact with the bottom of the inner cavity of the storage box, and then the vacuum pump is started to evacuate the ventilation groove 96 and the connecting groove 94 through the ventilation pipe 6, so that the bottom end of the ventilation groove 96 sucks the storage box; After the veneer material is cooled by the heat lamp 15, the motor 2 drives the shaft 3 to rotate counterclockwise, and the shaft 3, the plug rod 75, the rotating block 74, the sleeve plate 73, the sliding plug rod 72 and the fixed rod 71 are driven to make the sleeve plate 73 move vertically upward, and then move in the direction of the first lower mold 5. Finally, after the upper end of the sliding plug rod 72 hits the end of the fixed rod 71 close to the first lower mold 5, the shaft 3 continues to rotate, which will make the sleeve plate 73 move vertically downward, press the storage box into the first lower mold 5, so that the veneer material is covered on the outer wall of the storage box. After entering into the movable frame 105 and the first lower mold 5, the lower pressure ring 1012 will press the fixed blocks 107 on both sides and shrink inward, so that the fixed blocks 107 are separated from the first lower mold 5, and the limit block 1010 is bounced into the extension groove 108. At the same time, the guide groove 1018 on the connecting rod 104 is connected with the guide groove 1018 on the movable frame 105, and the suction hole 1019 makes the veneer material located at the upper end of the side wall of the storage box be sucked, and then the motor 2 is reversed, so that the connecting rod 104 drives the movable frame 105 to separate from the first lower mold 5 together, and the veneer material and the storage box also move together; Then, the storage box and the veneer material are moved into the second lower mold 8, so that the veneer material continues to be tightly attached to the outer wall of the storage box when it is not cooled. When the storage box and the veneer material move to the bottom of the inner cavity of the second lower mold 8, the lifting frame 92 will be squeezed upward by the second lower mold 8, so that the lifting frame 92, the heat dissipation groove 98 and the connecting pipe 93 move upward together, so that the heat dissipation groove 98 is connected with the heat dissipation port 97, so that the suction force of the bottom end of the upper mold 91 on the storage box no longer disappears, so that the gas flow in the ventilation groove 96 at the bottom end of the upper mold 91 is accelerated, thereby cooling the storage box tightly attached to the upper mold 91 and dissipating heat from the veneer material. After cooling, the vacuum pump is turned off, and the sleeve plate 73 and the movable frame 1 are moved upward by the vertical moving mechanism 7. 05 moves back to the first lower mold 5, removes the storage box that has been coated and cooled, and when the bottom end of the movable frame 105 is inserted into the first lower mold 5, the extrusion surface 109 will squeeze the limit block 1010 inward through the lower inclined surface 1013. At this time, the side inclined surface 1014 conflicts with the inner wall of the fixed sleeve rod 106. Since the vacuum pump is turned off, the gas in the cavity 1017 is no longer extracted. Therefore, under the action of the reset spring 103, the rotating block 101 rotates and resets, driving the limit block 1010 to rotate and move away from the extension groove 108, so that the limit block 1010 is disengaged from the movable frame 105. When the connecting rod 104 moves upward, the fixed block 107 automatically pops up, so that the first lower mold 5 and the movable frame 105 are engaged.
