The specific embodiment
As shown in Figure 1 and Figure 2.A kind of one-mold multiple-member even column single hole automatic-feeding magnetic shoe mould of arranging, include cutting plate and place die body 9 on the cutting plate, have a plurality of die cavitys 1 that equidistant ranks are arranged that are in the die body 9, die cavity 1 two ends accent is opened respectively in die body 9 end faces and bottom surface, and the columns of die cavity 1 has even number, from the first row die cavity, between the die cavity that row is adjacent in each odd column even column adjacent with its right side in the middle of the interval place be provided with respectively circular material feeding blind hole 2, circular material feeding blind hole 2 central shafts and die cavity 1 central axes, open in die body 9 bottom surfaces in circular material feeding blind hole 2 apertures, and a plurality of circular material feeding blind holes 2 consist of the blind holes row between each odd column even column adjacent with its right side, also be provided with a plurality of rectangle material holes 3 that are communicated with respectively in each odd column even column adjacent with its right side circular material feeding blind hole between the adjacent die cavity of the adjacent die cavity of row and row in the die body 9, rectangle material hole 3 central shafts are vertical with die cavity 1 central shaft, and a plurality of rectangle material holes 3 consist of rectangle material holes row between each odd column even column adjacent with its right side.
As shown in Figure 3.Cutting plate 4 one sides have material feeding main entrance 5, also having one center on the cutting plate 4 is communicated with material feeding main entrance 5 and the half-open total flow path groove 6 vertical with die body 9 upper cavities 1 column direction, total flow path groove 6 two ends notches are communicated with respectively runner groove 7, and two runner grooves 7 both sides of edges blind hole column position on position on the cutting plate 4 and die body 9 is corresponding one by one.Also be processed with seal groove 8 around total flow path groove 6, each runner groove 7.
In the utility model, when arranging as even column, die cavity 1 (explains with 4 row), if the adjacent die cavity column pitch of row is L, respectively at the position of center line of first row and secondary series: the L/2 place, the 3rd row and the 4th position of center line that is listed as: L/2 place, namely at the position of center line of odd column and its right side neighbouring even-numbered row, diameter perpendicular to the bottom surface of corresponding each die cavity processing is the circular material feeding blind hole 2 of Φ 10mm from the bottom, the columns of circular material feeding blind hole 2 is 1/2nd: 2 row of the columns of arrangement of molds, and the number of circular material feeding blind hole is 1/2nd: 8 of number of die cavity.
Process respectively a long 8mm, wide 2.5mm rectangle material hole 3 along being parallel to the bottom surface direction again, run through two die cavitys of row adjacent columns in odd column and its right side neighbouring even-numbered row, the rectangle material hole communicates with circular material feeding blind hole, and rectangle material hole and circular material feeding blind hole are " T " font and connect.The columns of rectangle material hole is 1/2nd: 2 row of the columns of arrangement of molds; The number of rectangle material hole is 1/2nd: 8 of the numbers of die cavity.
Blind hole depth will exceed rectangle material hole 2-3mm, and the height and position of rectangle material hole 3 is set according to the slip amount of the required injection of magnetic shoe base substrate.With the cutting plate 4 that die body matches, material feeding main entrance 5 diameters are Φ 20mm, in cutting plate 4 one sides, vertical direction along corresponding die cavity row is processed half-open total flow path groove 6 one, groove width 16mm, dark 18mm communicates with material feeding main entrance 5, position of center line in the row distance: L/2 place, namely with middle mould on circular material feeding blind hole 2 correspondence positions, respectively process respectively half-open runner groove 7 one, groove width 12mm, dark 18mm, the number of runner groove is 1/2nd: 2 row of the columns of arrangement of molds; Runner groove 7 communicates with total flow path groove 6, at the seal groove 8 that encapsulant is installed apart from all runner cell wall 2mm place periphery processing, groove width 4mm, dark 3mm.
Like this, slip is from the material feeding main entrance, through total flow path groove, runner groove, circular material feeding blind hole, after entering each circular material feeding blind hole, be diverted to two contiguous die cavitys from the rectangle material hole on top, do not interfere with each other with remaining die cavity material feeding, and material feeding has pressure, each cavity pressure is poor to be equated, until slip is filled with each die cavity, pressure balance, each die cavity shot equates, stops material feeding.This kind compact conformation, although two die cavitys of adjacent columns communicate, per two adjacent die cavitys share same circular material hole, the distance of slip from circular material hole top to two die cavitys, the material feeding latus rectum equates.Thereby in reaching at one time, suitable material feeding path, identical material feeding pressure differential, the purpose that shot equates.
Like this, each die cavity shot equates, is conducive to one-mold multiple-member blank density uniformity, improves green body quality.
