Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
As shown in Figure 1: as to the present invention includes nozzle body 1, water conservancy diversion shuttle 2, filtering bodies 3, installing and locating plate 4, sprue 5, the step 6 that is located by connecting, filter through hole 7, runner 8, nozzle body cavity 9 and spray-hole 10.
As shown in Figure 1: said nozzle body 1 is cylindric, is provided with in the said nozzle body 1 along the nozzle body cavity 9 of nozzle body 1 axial distribution; One end of nozzle body 1 is provided with spray-hole 10, and said spray-hole 10 is connected with nozzle body cavity 9, and the axis of the axis of spray-hole 10 and nozzle body cavity 9 and nozzle body 1 is consistent.Be provided with filtering bodies 3 in the nozzle body 1, said filtering bodies 3 stretches in the nozzle body 1 corresponding to the other end that spray-hole 10 is set from nozzle body 1.Filtering bodies 3 is provided with installing and locating plate 4 corresponding to the other end that stretches into nozzle body 1; And filtering bodies 3 forms the step 6 that is located by connecting through installing and locating plate 4; And on the step surface of step 6 that is located by connecting, be provided with connecting thread; Thereby make nozzle body 1 and filtering bodies 6 be connected through screw threads for fastening, filtering bodies 3 is carried out installing and locating with nozzle body 1 through installing and locating plate 4.
Be provided with the sprue 5 that connects filtering bodies 3 in the filtering bodies 3, through sprue 5 can raw material input nozzle body 1 with molten condition in.Filtering bodies 3 is provided with water conservancy diversion shuttle 2 corresponding to an end that stretches into nozzle body 1 end, and an end of said water conservancy diversion shuttle 2 stretches in the filtering bodies 3, and is fastenedly connected through screw thread and filtering bodies 3.Water conservancy diversion shuttle 2 adopts the high-abrasive material Precision Machining, and adopts Technology for Heating Processing, and the two ends of water conservancy diversion shuttle 2 are all tapered, have good guiding shunting action.The axis of the axis of water conservancy diversion shuttle 2 and filtering bodies 3 is located along the same line, and the axis of the axis of filtering bodies 3 and nozzle body 1 is located along the same line.The outer peripheral face of filtering bodies 3 is provided with some equally distributed runners 8, and said runner 8 is arranged with on filtering bodies 3, and runner 8 is along the distribution of lengths of filtering bodies 3.Runner 8 is provided with some filtration through holes 7, and said runner 8 is connected with sprue 5 through filtering through hole 7.The external diameter of water conservancy diversion shuttle 2 is less than the width of nozzle body cavity 9; Thereby form the shunting chamber between the inwall of water conservancy diversion shuttle 2 and nozzle body 1; Said shunting chamber is connected with spray-hole 10, nozzle body cavity 9, runner 8 and sprue 5, thereby can outwards spray from spray-hole 10 through shunting back, shunting chamber through the raw material of sprue 5 entering molten conditions.The aperture of filtering through hole 7 is 1.5mm ~ 5mm, and the size of filtering through hole 7 apertures is according to the different size choice of equipment.Usually, the aperture of filtering through hole 7 is 2mm, and through filtering through hole 7 filtering diameters greater than 2mm, length is greater than the impurity of 2.5mm.
