step 2: then, a second sliding block 2-2 on the upper part of the lower die 2 moves rightwards to be attached to a fixed block 2-3, a third sliding block 2-4 moves leftwards to be attached to the fixed block 2-3, and a fifth sliding block 2-7 moves downwards to be attached to the fixed block 2-3, so that the attachment of the upper part of the lower die 2 is completed; meanwhile, the first slide block 2-1 at the lower part of the lower die 2 moves rightwards, the fourth slide block 2-5 moves leftwards, the sixth slide block 2-8 arranged on the slide block bracket 2-6 slides on the slide block bracket 2-6 and is jointed with the slide block bracket 2-6, then the first slide block 2-1 and the fourth slide block 2-5 are jointed with the slide block bracket 2-6 and the sixth slide block 2-8 to finish the jointing of the lower part of the lower die 2, after the upper part and the lower part of the lower die 2 are respectively jointed,
and step 3: respectively adsorbing the lower half Polyurethane (PUR) epidermis to the lower part of the lower die 2 through the second vacuum channels 2-12, the fourth vacuum channels 2-15 and the sixth vacuum channels 2-18, vacuum adsorbing the silica gel imitation epidermis to the upper part of the lower die through the first vacuum channels 2-11, the third vacuum channels 2-14 and the fifth vacuum channels 2-17, after completely adsorbing in place,
and 4, step 4: starting to slide the lower part of the lower die 2 integrally to be attached to the upper part of the lower die 2, clamping and sealing the Polyurethane (PUR) skin and the edge part of the silica gel imitation leather through a first imitation leather-clamping groove 2-10, a second imitation leather-clamping groove 2-13 and a third imitation leather-clamping groove 2-16 of the lower die 2, starting to pour a foaming mixing head, enabling an upper die 1 to fall down to be matched with the lower die 2, sealing and curing for a set time,
and 5: the upper die 1 rises, the first sliding block 2-1 and the second sliding block 2-2 of the lower die 2 move leftwards, the fourth sliding block 2-5 and the third sliding block 2-3 of the lower die 2 move rightwards, the sixth sliding block 2-8 arranged on the sliding block bracket 2-6 is separated from a set distance, so that the foamed half-skin instrument panel is not interfered with the lower die 2, the fifth sliding block 2-7 moves upwards, the foamed half-skin instrument panel body is ejected, and demoulding is finished.
