The joint, bottom surface of described upper left loose piece and upper right loose piece is outstanding downwards respectively to be formed with a flange with positioning action, then be formed with in the upper surface corresponding position of loose piece down can with the corresponding groove of above-mentioned two flange shape.
Described groove is a dovetail groove.
The integral die method of fiberglass centrifugal blower fan blade wheel provided by the invention is carried out according to the following order step:
(1) makes the core that steel, inner surface chromium plating and inner chamber have the upper die and lower die of heater and 10 group aluminum alloy materials and outer surface chromium plating and be made up of above-mentioned loose piece, upper left loose piece and upper right loose piece down respectively according to the project organization of the shroud of fiberglass centrifugal blower fan blade wheel, blade, hub disk;
(2) inner surface of mould and the outer surface of loose piece are evenly coated paraffin release agent;
(3) reaching the upper left loose piece of 10 core assembly moulds, upper right loose piece down, loose piece is installed in the patrix cavity successively;
(4) the SMC felt of in the gap of core, packing thermosetting resin into or cutting;
(5) on forcing press, install the upper and lower mould that loose piece is housed, then heating and mould pressing 10 minutes under the temperature of 200 tons pressure and 170 ℃;
(6) open upper and lower mould, take out the impeller workpiece that has loose piece, take out every core assembly mould successively and obtain the impeller workpiece according to the order of following loose piece, upper right loose piece and upper left loose piece then;
(7) burr of impeller are repaired integral body to be made the fiberglass centrifugal blower fan blade wheel.
The integral die mould of fiberglass centrifugal blower fan blade wheel provided by the invention and method thereof are that interlobate core is divided into three interconnective loose pieces, can not only solve the problem that core after the integral die moulding can't depanning like this, and can improve the bulk strength of impeller, thereby can enhance productivity, increase the service life of blade strength and prolongation blower fan.
