Second embodiment of liner is shown in Fig. 6-8.Liner 109 comprises that one generally is the body 111 of arc, has 115, one first side 117a of 113, one outer surfaces of an inner surface, a first side 117b, a front 119a and a back 119b.One first side flange 121 extends from body along side 117a and a forward flange 123 extends along front 119a.One second side flange 125 extends along back 119b along side 117b extension and a rear flange 127.Flange 121,123,125 and 127 have a top is about 1/2 of thickness between liner body 111 inner surfaces and the outer surface to bottom thickness.Flange 121 and 123 all has top surface, is the continuation of the outer surface 115 of liner body; And flange 125 and 127 all has basal surface, is the continuation of the inner surface 113 of liner body.Therefore, as can be seen from Figure 6, body shows as two square tops that are placed on mutually in top plan, and diagonal angle biasing mutually.

In order to assemble inner cores by liner 109, liner is the relation assembling that overlaps mutually with its flange, shown in Fig. 7 and 8.As liner 9, when can preventing to wear and tear, the bonding relation of the flange of liner 109 comes off from inner core.Though not shown in the drawings, the limit of flange 121 and base side 117b can form groove, with pin-receiving 25.

Figure 11-16 shows the 3rd embodiment of lining liner.Lining liner 209 comprises that one generally is the body 211 of arc, has an inner surface 213, one outer surfaces 215, side 217 and front and rear side 219.Each liner preferably is about 35 °-40 ° circular arc.For interval liner 209, and the inner core 205 and urceolus 203 of therefore interval liner 209 formation, each liner 209 has rib or the fin 221 that the diagonal angle extends at its outer surface 215.Fin 221 is positioned on the liner 209, makes when a plurality of liners are connected to form inner core 205, and the fin on liner is against the relevant fin of adjacent liner, to provide along the surperficial continuous fin of tube.Inner core 205 is preferably porose, makes the molding sand that separates from foundry goods can fall the space 207 between inner core and the urceolus.Therefore liner 209 has a plurality of holes or bores a hole 222, makes molding sand can fall in the space 207 between inner core and the urceolus.

For liner 209 is locked mutually, each liner comprises a tongue 231, from front and rear side 219 near extending and on four angles of lining body 211, generally be the otch 233 of rectangle in the center.When two liners 209 during along the mutual placed adjacent of its side 217, otch 233 limits grooves 235 (Figure 15).The groove reception that forms is placed on along the tongue 231 of another liner 209 of front and rear side 219 contiguous two liners of liner, as what discussed at the liner 9 of Fig. 1 in the above.Tongue piece 231 extends on the whole width between the surfaces externally and internally 213 and 215 of body 211.But the outer surface 215 of body comprises and the part 236 of a rise covers otch 233.Therefore, groove 235 is at a side closure.When lining 205 is assembled, rise part or cover plate 236 and lean against on the tongue piece 231, thus liner 209 interlockings that difference that will be adjacent is arranged.

In order to keep lining liner 209 on the throne mutually, to form lining 205, liner 209 is included in the flange 241 that liner side 217 is extended downwards.This flange extends along the edge of liner side 217 at otch 233.Flange 241 comprises bolt hole 243.In the lining 205 that assembles, 243 alignment of the bolt hole of flange 241 and adjacent liner 209,243, one nuts in hole that bolt 245 passes adjacent flanges 241 are added in the end of thread of bolt, and liner is held in place.Be appreciated that the single liner in the lining is fastened in this way.Though adjacent row does not tighten together, they can be secured together.The tongue piece 231 of one row's liner interacts with the groove of adjacent row's liner 235, makes row's liner not with respect to another row's liner landing.

In addition, hole 251 is formed on the basal surface 253 of the fin 221 of liner.Hole 251 receives a pin 255.Pin 255 has a head 257, and it is welded to urceolus 203 and a body 259 extends radially inwardly from urceolus 203, enters into the base apertures 251 of fin 221.The shape complementarity in pin body 259 and fin hole 251.They can be circular, square or any other required shape.Adopt pin 255 each lining liner 209 to be fixed to two places of urceolus 203.Pin 255 is positioned at the two ends of the fin of each liner 209, and pin 255 is the relative position of lining liner and urceolus 203 fixedly.Therefore, plurality of rows liner 206 can not move with respect to urceolus 203.And the interaction of pin 255 (they are welded on the urceolus 203) and liner 209 will prevent row's liner moving with respect to adjacent row's liner.

Liner 209 is described as does not need a lining locking key to assemble, for example the lining locking key 25 of Fig. 2-3 or 9-10.But, can use a lining locking key 325, shown in Figure 17-18.In the case, the side of liner is provided with a groove or groove, is similar to the groove or the groove 23 (Fig. 4) of lining liner 9.Key 235 is shown as and is similar to key 25, but also can be similar to the key 25 of Fig. 9-10 '.Key 325 and key 25 or 25 ' different being, key 325 is provided with bolt hole 327 at the sidewall 343 of body 341.Bolt hole 327 aligns with the bolt hole 243 of flange 241.Then, bolt 245 passes the bolt hole 243 of lining liner 209 and the bolt hole 327 of lining locking key.Interchangeablely be, keep bar can be used to the place of lining locking key 325, in for example commonly assigned 5,638,890,5,638,887 and 4,502,808 disclosed (all these are incorporated herein for reference).

Can understand, liner of the present invention is cooperated with each other, to prevent that liner separates from lining when a pin weares and teares or fractures.Though some is loose for the liner possibility, the cylinder machine still can be operated, at least a bit of time before liner must be changed.This will allow the machine orderly closedown, rather than the emergency shutdown of machine, if liner separates from lining, then need anxious stopping.Pin provides level and smooth and continuous transition between the plate, and what make that foundry goods and sand are only seen lining 5 continuous does not interrupt surfaces externally and internally and basically along continuous unbroken basically fin of liner outer surface.

Can not make various variations because do not leave scope of the present invention, therefore the description above or the expression in the accompanying drawing all are schematically rather than limit.For example lining liner 209 can change over the flange that makes on liner one side and comprises axially extended post, and makes the flange on the liner opposite side comprise the hole that receives this post.Therefore, the post of a liner will be received in the flange hole of adjacent liner, not need disengagement bolts.This example just schematically.
