After using above structure, compared with prior art, this utility model is horizontal due to being provided with dashpot below sprue Running channel is two, and two cross gates are located at the both sides of sprue, and two cross gates on the side wall of sprue with sprue Connect, two ingates of each cross gate correspondence the same side, then fluid enters back into horizontal pouring under the cushioning effect of dashpot In road so that the flow velocity of fluid and the uniformity of flow preferably, so as to reduce injection defect, improve the yield rate of production;And Two cross gates connect on the side wall of sprue with sprue, and flow velocity and flow into the fluid of cross gate are caused again Uniformity more preferably, can further improve the yield rate of production, and reduce production cost.Therefore this utility model has flow velocity and stream The uniformity of amount is preferable and injection-molded finished rate is higher and the characteristics of relatively low production cost.
Used as improvement, the dashpot is " T " font structure being made up of translot and vertical slot, and vertical slot is located at the upper of translot Side, and vertical slot upper end connects with sprue, vertical slot lower end connects with translot, connection of the cross gate on the side wall of sprue The lower end at place is concordant with the upper end of vertical slot;After then so arranging, larger space will not be taken, and the buffering effect of convection cell is more It is good so that the flow velocity of the fluid for entering into and the uniformity of flow more preferably, can further improve the yield rate of production, and reduce Production cost.
Used as further improvement, the cross gate is " C " font structure, and two cross gates are along the axis shaft pair of sprue Claim;After then so arranging so that the overall heat of mould is relatively more uniform, and the flowing of fluid is smoothly, and then reduce injection Defect, improves yield rate.
As further improving, the diameter of the vertical slot less than sprue lower end diameter, and vertical slot with diameter greater than The width of connectivity part of the cross gate on the side wall of sprue;After then so arranging so that the fluid in sprue can preferentially enter In entering vertical slot, so as to preferable cushioning effect can be played so that when fluid clamp-ons cross gate, the flow velocity of fluid and flow it is equal Even property is further improved, and further improves the yield rate of production.
As further improving, two grades of cross gate connections, two grades of horizontal strokes are provided between the cross gate and ingate Running channel is corresponded with ingate, and two grades of cross gates are connected with the side wall of cross gate;After then so arranging so that in cross gate Fluid again through once buffering so that the flow velocity of fluid and the uniformity of flow are further improved, and further improve production Yield rate.
Used as further improving, the cross section of the ingate is wedge structure, and the thick part of wedge structure is poured with horizontal Road is connected;And the top view of ingate is triangle, one side of triangle connects with cross gate;After then so arranging, fluid enters Enter die cavity flow velocity and flow uniformity more preferably, so as to further improve the yield rate of production.
Used as further improving, the diameter of the sprue upper end is less than the diameter of sprue lower end;Then so arrange Afterwards so that the fluid into sprue has the process of a reduction of speed, it is the uniformity of fluid such that it is able to reduce the generation of bubble It is consequently increased, so as to reduce injection defect, improves the yield rate of production.
