The foaming of the refrigerator body is a very important link in the production and manufacturing process of the refrigerator, and how to improve the production efficiency of the foaming link of the refrigerator body is very important. The existing foaming process of the box body comprises the following steps: opening a mold: the top of the mould is fixed, and the bottom and two sides of the mould move downwards through the servo motor and move to the box entering position. Secondly, demolding the box body: if the box body which is foamed is arranged in the mold, the box body is removed from the mold; if there is no box in the mold, this step is skipped. Thirdly, feeding the box body into a mold: and (4) enabling the box body to be foamed to enter a die. Mold closing: the mold moves upward from the mold-in position to the mold-closing position. Foaming the box body: after the die assembly is completed, injecting foaming raw materials to start foaming, and after the foaming is completed, opening the die for more than one cycle.
The current box entering position is consistent with the die changing position. The box of different models is probably required to be produced to same mould, consequently need to change box centre form, and the centre form adopts fixed buckle pole to fix at the mould top, puts down dead lever buckle and centre form together during the change, changes new centre form and after the installation dead lever buckle, fixes again to the mould top.
Wherein the holistic height of dead lever buckle is 400mm, and the centre form need descend 400mm +50mm (safe distance) during the retooling apart from, and the thickness of treating the foaming box only be 60mm, treat when treating that foaming box delivery location and retooling position are unanimous that the box and baffle clearance of treating to foam are too big when same height to when foaming, mould lifting height is great, and the time is longer, thereby influences holistic foaming efficiency.
