Abstract
The invention relates to a molding method for vertical pouring production of a blade without a sand box. The molding method is as follows: preparing upper and lower pattern beams according to the size of the blade, flatly placing a blade bottom body model on a platform, surrounding and covering a blade wood mold with a core box frame and carrying out vertical pouring to produce the blade by using front and back surface core assembling and box assembling molding and using the upper and lower pattern beams to clamp a sand mold. According to the molding method, the heavy sand box is replaced with the upper and lower pattern beams; the weight of the whole sand mold is reduced; the production is not limited by the capacity of a crane device and the production capability is improved; and besides, the pattern beams have flexible universality and can be repeatedly used and the cost is saved.

4) lower panelgirder is placed on above lower core box, arbor and lower panelgirder are connected and fixed;
5) back-up sand Chong face of blade integral sand core;
6), after the sclerosis of front core, by lower panelgirder and front integral sand core turn-over, make lower panelgirder be placed on platform, the blade wooden model back side upward;
7) lower core box is covered on lower core outer surface again, upper core box is positioned on lower core box, perimeter alignment;
8) at blade wooden model backside surface welding arbor;
9) upper panelgirder is placed on above upper core box, and is connected and fixed with back side arbor;
10) back-up sand Chong vacuum side of blade integral sand core;
11), after core sclerosis, remove core box frame, back side core of slinging, upset is placed on platform, takes out blade wooden model;
12) sand mold is repaired, spray paint, oven dry, mould assembling;
13) by upper and lower panelgirder clamp and reinforcing bar tension firm welding;
14) be placed horizontally in pit, vertically erect;
15) moulding by casting.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention replaces thick and heavy sandbox with upper and lower panelgirder, alleviates the weight of whole sand mold, produces and does not limit by crane gear ability, improves production capacity.And panelgirder tool versatility flexibly, reusable edible, cost-saving.
