Preferably, the cover half with the die-casting forms the design cavity between the movable mould, the inside inserted of motor base is equipped with the motor, the motor top is equipped with the fore-set, the fore-set with the welding of activity top dish.
Preferably, a plurality of hydraulic cylinders are arranged below the movable die.
Preferably, the cylinder block is provided with a cylinder, and the cylinder is provided with a rotary dovetail piece.
Preferably, the overflow groove and the exhaust cavity are overlapped in a die-casting mode to form an exhaust gap.
Compared with the prior art, the utility model has the beneficial effects that:
the movable mould passes through the pneumatic cylinder, and stable accurate orderly carries out the die-casting with the cover half coincidence, adopts dovetail piece and movable mould to cooperate the die-casting, and the area of contact of product and movable mould when reducing the die-casting has the cooling tank to accelerate the cooling speed of product in, and the movable head plate is ejecting during the drawing of patterns, and the risk of product loss when reducing the drawing of patterns has improved the work efficiency of mould.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An impeller mould comprises a mechanism body, wherein the mechanism body comprises a movable mould and a fixed mould 1; the movable die comprises a cooling groove 15, a positioning salient point 3, an overflow groove 12, a movable top plate 6, a motor base 10 and a cylinder seat 5, wherein the cooling groove 15 is arranged inside the movable die 11 in a penetrating manner, the positioning salient point 3 and the overflow groove 12 are arranged on the upper surface of the movable die 11, the motor base 10 is arranged at the center of the bottom surface of the movable die 11, and the cylinder seat 5 is arranged on the surface of the side wall of the movable die 11; the cover half 1 includes exhaust cavity 4, post 2 and positioning groove 13 that take shape, positioning groove 13 sets up 1 bottom surface of cover half, cover half 1 with the movable mould 11 passes through location bump 3 with the die-casting is fixed a position to positioning groove 13 clearance fit.
The fixed die structure is characterized in that a fixed cavity is formed between the fixed die 1 and the movable die 11 through die casting, a motor 9 is arranged in the motor base 10 in an embedded mode, a top column is arranged above the motor 9 and welded with the movable top plate, the motor 9 adopts a stepping motor 9, a plurality of hydraulic cylinders 16 are arranged below the movable die 11, a cylinder 14 is arranged on the cylinder seat 5, a rotary dovetail piece 7 is arranged on the cylinder 14, and an exhaust gap is formed between the overflow groove 12 and the exhaust cavity 4 through die casting and overlapping.
The working principle is as follows: before die casting, the dovetail piece 7 is in a bending and containing mode and is contracted in the movable die 11 through the air cylinder 14, the movable top plate 6 is stably placed in the middle of the movable die 11, the movable top plate 6 is detachably installed and fixed on the top column 8, and when the die casting machine is ready for work, the part is stably placed in the middle of the movable die 11 and completely coincides with the depression of the movable die 11; before the die-casting, hydraulic cylinder 16 under the movable mould 11 stably moves upwards and overlaps with fixed mould 1 and carries out the die-casting when dovetail piece 7 extends out, then the metal liquid is poured into, and the air gets into the exhaust cavity 4 exhaust through overflow launder 12, and overflow launder 12 can prevent that the metal liquid from blockking up the exhaust opening, stops the exhaust, and the coolant liquid cools off the product through cooling tank 15 fast afterwards, and then hydraulic cylinder 16 moves downwards, and dovetail piece 7 contracts, and the ejecting foundry goods of movable tray, the impeller is accomplished.
