Description

TECHNICAL FIELD

[0002] In the current large-scale production of automobile chair cushions, the "raw material is poured into the mold for hot pressing and shaping" is the core process for mainstream materials such as memory foam, latex, and composite foam, and is particularly suitable for the needs of modern automobiles for chair cushions "ergonomic modeling + multi-layer functional composite". The core logic is: pour the liquid or semi-solid raw material (such as memory foam foaming raw liquid, latex slurry, or pre-mixed antibacterial fabric pre-impregnated material, anti-slip silicone layer raw material) into the customized mold cavity (the cavity shape is completely matched with the final chair cushion shape, including the waist rest protrusion, the hip support deep cavity, and the ventilation hole structure) according to the preset ratio; then the equipment heats and pressurizes the mold (the temperature is usually controlled at 60-90℃, so that the raw material is cross-linked and solidified or softened and shaped); after the raw material is completely shaped, the mold is opened and the chair cushion product is taken out.

[0028] Meanwhile, the contents not described in detail in the specification all belong to the prior art known to those skilled in the art.

[0029] When working, first, heat pressing and shaping preparation is carried out, the memory cotton, latex and other chair cushion raw materials are poured into the cavity of the lower die 4, and then the lifting cylinder 3 at the top end of the rack 2 is started, the output end of the lifting cylinder 3 pushes the upper die 5 to vertically descend until the upper die 5 and the lower die 4 are accurately matched; After the mold is closed, the resistance heating wires on the inner walls of the upper die 5 and the lower die 4 are synchronously powered on to heat the raw materials in the mold, and at the same time, the lifting cylinder 3 continuously provides pressure, so that the raw materials are fully filled in the cavity and crosslinked and solidified under the action of "high temperature + pressure", forming a chair cushion prototype conforming to the specifications, and completing the heat pressing and shaping process. Immediately after hot pressing and shaping, the vibration demolding stage is entered, the driving motor 74 in the driving assembly 7 on the bottom plate 1 is started, and the output shaft of the driving motor 74 drives the worm 75 to rotate: on the one hand, the worm 75 is linked with the worm gear 76 in meshing, drives the second rotating rod 72 on the second support 71 to rotate, and the second bevel gears 73 at both ends of the second rotating rod 72 are respectively meshed with the first bevel gears 613 on the first support 65, thereby driving the first rotating rod 612 and the cam 611 at the end to rotate; when the cam 611 rotates, the extrusion plate 64 in the extrusion assembly 6 is extruded, so that the extrusion plate 64 drives the sliding rod 62 penetrating through the vertical plate 61 to slide, and at the same time, the first spring 63 on the sliding rod 62 is compressed; the long plate 66 at the other end of the sliding rod 62 moves together, pushes the moving column 69 in the fixed cylinder 67 and the rubber block 610 at the end to impact the outer wall of the lower mold 4; when the concave end of the cam 611 turns to the extrusion plate 64, the first spring 63 releases the elastic force to push the extrusion plate 64 to reset, at the same time, the second spring 68 connecting the long plate 66 and the moving column 69 in the fixed cylinder 67 elastically rebounds, drives the moving column 69 and the rubber block 610 to retreat, ensures that the extrusion plate 64 is always attached to the surface of the cam 611, avoids the jamming of the cam 611, and makes the rubber block 610 continuously reciprocate and impact the lower mold 4, so as to generate high-frequency micro-vibration to destroy the adsorption force between the chair cushion and the mold cavity, and realize easy demolding. At the same time of vibration demolding, the device synchronously starts the heat dissipation function: the end of the worm 75 away from the driving motor 74 penetrates through the mounting plate 77 and is fixed with the driving wheel 710; the driving wheel 710 drives the driven wheel 79 of the rotating shaft on the mounting plate 77 to rotate through the belt 711, the rotating speed of the driven wheel 79 is improved because the diameter of the driving wheel 710 is larger than that of the driven wheel 79, thereby driving the rotating fan blade 78 to rotate at high speed, directional airflow is generated to blow to the upper mold 5 and the lower mold 4, the heat of the mold and the chair cushion is quickly taken away, the cooling time is shortened, the surface temperature of the mold is reduced, the safety of subsequent operation is ensured, and finally the whole chair cushion hot pressing forming process is completed.
