Grate flow channel 8 comprises and is positioned at the drawer at movable side flow path portion 80 that approaches die cavity 4 sides and is positioned at the fixation side flow path portion 90 that approaches the exhaust trackside.The major part of grate flow channel 8 is drawer at movable side flow path portion 80.Drawer at movable side flow path portion 80 consists of the groove on the divisional plane 10 that is formed on moveable die 3.Particularly, drawer at movable side flow path portion 80 as shown in double dot dash line in Fig. 5 (a), in Fig. 6 shown in cutaway view like that, be the space between the divisional plane 20 of the groove that forms on But moving die 12 and fixed mould 2.Drawer at movable side flow path portion 80 there are a plurality of transverse slot portion 81 and by the end of this transverse slot portion 81 vertical slot part 82 connected to each other, drawer at movable side flow path portion 80 alternately changes direct of travel and simultaneously towards upside in left and right by vertical slot part 82 left and right alternate configurations.Drawer at movable side flow path portion 80 forms that width is certain and the degree of depth is also certain.The transverse slot portion 81 of the upper in release chamber 4 is positioned near position lower than valve gear 9 and that valve gear 9 is farthest.
Fixation side flow path portion 90 consists of the groove formed on the divisional plane 20 at fixed mould 2.Particularly, comprise the vertical slot part 91 be formed on fixed die 22 and be formed on circular depressions 42 and the vertical slot part 41 on the front surface 31a of main body 31 of valve gear 9.Vertical slot part 91 of fixed die 22 is continuous with a linearity with vertical slot part 41 of main body 31, and both width and the degree of depth are all identical.Width and the deep equality of the transverse slot portion 81 of the width of vertical slot part 91 of fixed die 22 and the degree of depth and But moving die 12.Vertical slot part 91 of fixed die 22 is communicated with the transverse slot portion 81 of upper of But moving die 12 and vertical slot part 41 of main body 31.Vertical slot part 91 of fixed die 22 is formed on the position of slightly leaving from the end 81a of the transverse slot portion 81 of the upper of But moving die 12, with the whole width of the transverse slot portion 81 of the upper of But moving die 12, links.The end that the end 81a of the transverse slot portion 81 of the upper of But moving die 12 is drawer at movable side flow path portion 80.In addition, the divisional plane of moveable die 3 10 and circular depressions 42 and vertically the place ahead of slot part 41 is opposed, and the divisional plane 10 of moveable die 3 is also with in vertical slot part 91, to approach the place ahead of part of vertical slot part 41 of valve gear 9 opposed.That is, in the divisional plane 10 of moveable die 3 and vertical slot part 91, the place ahead of the part except the linking portion of the transverse slot portion 81 with upper is opposed.
The molding gradient α of drawer at movable side flow path portion 80 is fixing in whole zone, is for example 10 °～15 °.The molding gradient β of fixation side flow path portion 90 is fixing in whole zone, is for example 20 °.That is, the molding gradient of vertical slot part 91 of the molding gradient of vertical slot part 41 of the molding gradient of circular depressions 42, main body 31 and fixed die 22 is all β.The molding gradient β of fixation side flow path portion 90 is larger than the molding gradient α of drawer at movable side flow path portion 80.In addition, the side face 32a of spool 32 is for to become the conical surface of path towards front side, and its angle of inclination γ is larger than the molding gradient β of circular depressions 42.That is, there is the relation of α<β<γ.But, can be also α<β≤γ.
Then, the casting die of using above-mentioned mould 1 is described.At first, the right side that moveable die 3 is Fig. 1 towards the direction that approaches fixed mould 2 is moved, make the divisional plane 10 of moveable die 3 carry out matched moulds with divisional plane 20 butts of fixed mould 2.Under the state of the spool 32 of opening valve gear 9, to sleeve 23, inject motlten metal.With low speed, the left to Fig. 1 moves at first to make push rod 24.Now, the gas that vavuum pump attracts in die cavity 4 via blast pipe 29, steam vent 30, grate flow channel 8.Afterwards, make push rod 24 with high-speed mobile, make motlten metal be full of die cavity 4.When motlten metal contacts with sensor by cast gate 7 inflow grate flow channels 8, sensor senses is sent signal to motlten metal, and by this signal, electromagnetic switching valve 34 will switch to compressed-air actuated supply route the cup 33a of working cylinder 33.By by compressed air, the cup 33a to working cylinder 33 supplies with, spool 32 retreats, and cuts off steam vent 30.Motlten metal arrives spool 32 by drawer at movable side flow path portion 80 and fixation side flow path portion 90.
And, when the motlten metal of die cavity 4 cooling and, after solidifying, moveable die 3 is moved to the left side of Fig. 1 and leave fixed mould 2.Because the molding gradient β of fixation side flow path portion 90 is larger than the molding gradient α of drawer at movable side flow path portion 80, the motlten metal therefore solidified in fixation side flow path portion 90 successfully leaves from fixed mould 2.Owing to there being spool 32 in circular depressions 42, therefore the motlten metal that the motlten metal solidified in circular depressions 42 solidifies in than the motlten metal solidified in the other parts of fixation side flow path portion 90, than vertical slot part 91 of the vertical slot part 41 in main body 31 and fixed die 22 is complex-shaped, and away from drawer at movable side flow path portion 80, the resistance while therefore separating from fixed mould 2 is large due to.Yet, because the molding gradient β of circular depressions 42 is larger than the molding gradient α of drawer at movable side flow path portion 80, the angle of inclination γ of the side face 32a of spool 32 is larger than the molding gradient β of circular depressions 42, and the motlten metal therefore solidified in circular depressions 42 successfully separates from circular depressions 42 and spool 32.And, because the molding gradient β of fixation side flow path portion 90 is larger than the molding gradient α of drawer at movable side flow path portion 80, the motlten metal therefore solidified in fixation side flow path portion 90 can not be cut off near the bond sites of fixation side flow path portion 90 and drawer at movable side flow path portion 80.So, even on valve gear 9, knockout pin is not set, also can make the motlten metal solidified separate reliably from fixed mould 2.Afterwards, the knockout pin that the position of leaving by the part from the opposed moveable die 3 of valve gear 9 arranges, the motlten metal that will solidify in drawer at movable side flow path portion 80 or die cavity 4 is released and is separated from moveable die 3.Especially because the part with circular depressions 42 and vertical opposed moveable die 3 of slot part 41 does not form groove, smooth divisional plane 10 is with circular depressions 42 and vertically slot part 41 is opposed, therefore even near the part with the opposed moveable die 3 of valve gear 9 or its, knockout pin is not set, can easily the motlten metal solidified be separated from moveable die 3 yet.So, around the spool 32 of valve gear 9, on moveable die 3 and fixed mould 2, do not need knockout pin.
In addition, the molding gradient β of fixation side flow path portion 90 is fixing in whole zone, but for example also can be for the molding gradient α of the molding ratio of slope drawer at movable side flow path portion 80 of circular depressions 42 only is large, the molding gradient of the other parts of fixation side flow path portion 90 equates with the molding gradient α of drawer at movable side flow path portion 80.In addition, also can make the molding gradient α of molding ratio of slope drawer at movable side flow path portion 80 of vertical slot part 41 of vertical slot part 91 of fixed die 22 and main body 31 large, and make the molding gradient of vertical slot part 41 of vertical slot part 91 of molding ratio of slope fixed die 22 of circular depressions 42 and main body 31 large.The molding gradient α of the molding ratio of slope drawer at movable side flow path portion 80 by least making circular depressions 42 is large, thereby does not need to arrange knockout pin on valve gear 9, can simplify the structure of valve gear 9.And, also easily carry out the maintenance of valve gear 9.
Owing to as described above valve gear 9 being imbedded to fixed die 22, therefore on fixed mould 2, form a plurality of for the slotting logical intercommunicating pore of blast pipe 30 connecting elements such as grade for being connected with valve gear 9.Intercommunicating pore forms along the vertical direction, and is formed into the upper surface of fixed support 21 in the mode by fixed support 21 up/down perforations from the accepting hole 25 of fixed die 22.Particularly, in the front portion of fixed mould 2, a substantial transverse row ground is formed with five intercommunicating pores altogether.That is, as shown in Figure 8, while observing from front side, be formed with the intercommunicating pore 110 of blast pipe 29 use in the central authorities of left and right directions, be formed with respectively the intercommunicating pore 112 of cooling tube 100 use in its both sides, and be formed with respectively the intercommunicating pore 114 of location use in its more lateral.In addition, although not shown, the bottom of intercommunicating pore 114 of location use is that not shown threaded rod is screwed into this screwed hole from top, and the bottom of this threaded rod engages with the recess 46 of the location use of valve gear 9 with respect to the top screwed hole of refinement more.
