Fixed edge 100 is arranged to face each other and separate.At this moment, fixed edge 100 maintains stationary state.
Unsteady limit 200 is arranged between fixed edge 100, and two vertical sections on the limit 200 of floating are the state at fixed edge 100 in contact.At this moment, two vertical sections on unsteady limit 200 are subject to the pressurization of fixed edge 100 and fixed edge 100 and unsteady limit 200 are close to.Accordingly, in the time that motlten metal is injected between fixed edge 100 and unsteady limit 200, prevent that motlten metal from passing through the contact portion outflow on fixed edge 100 and unsteady limit 200.
And the limit 200 of floating can be moved between fixed edge 100.The large young pathbreaker of the foundry goods therefore, forming in size-changeable casting mould 10 is changed.At this moment, move each other round about on the limit 200 that can make to float, thereby change the size of casting mould.And, mobile another unsteady limit 200 in the situation that of can also being fixed on a unsteady limit 200, thereby the size of change casting mould 10.
On two vertical sections on the unsteady limit 200 contacting with fixed edge 100 in addition,, form recess 211.Recess 211 is concave shape with respect to two vertical sections on the limit 200 of floating, and reduces the contact area of floating between 200 two, limit vertical section and fixed edge 100 surfaces.Therefore, can prevent from floating limit 200 fixed edge 100 while moving surface because of with the friction damaged on unsteady limit 102.
And, due to the friction on fixed edge 100 and unsteady limit 200, on the surface of fixed edge 100, may produce trickle scratch damage, but be embedded into because scratching the fragment (chip) or the chip that fall down from the surface of fixed edge 100 gap being formed by recess 211 and fixed edge 100.Therefore, can prevent that fixed edge 100 surface damages from expanding.
And, can prevent that the motlten metal that is injected into casting mould because of the expansion of fixed edge 100 surface damages from forming the phenomenon of inhomogeneous and fragile solidification layer on fixed edge 100 surfaces of damaged, thereby also can carry out stable casting manipulations when change is big or small.
And as mentioned above, the recess 211 on the limit 200 of floating can prevent the surperficial damage of fixed edge and the problem causing thus, thereby can also extend life-span and the replacement cycle of mold 10.
Fig. 3 is the stereogram that is formed on multiple embodiment of the recess 311 on the unsteady limit 200 of the size-changeable casting mould 100 shown in Fig. 1.As shown in FIG. 3, recess 311 can be formed on the vertical section 201 on the limit 200 of floating in a variety of forms.In addition, below, the vertical section 201 on the limit 200 of floating will be called contact-making surface.
Contact-making surface 201 is formed by outer side edges 212, inner side edge 213, upper side edge 214 and lower side 215.Outer side edges 212 is the limit that is positioned at the outside of casting mould 10; Inner side edge 213 is the limit that is positioned at the inner side (, motlten metal side) of casting mould 10; Upper side edge 214 is the limit of the upside end of connection outer side edges 212 and inner side edge 213; Lower side 215 is the limit of the downside end of connection outer side edges 212 and inner side edge 213.
The first embodiment figure 1 illustrates the example that recess 311 is only recessed to form on contact-making surface 201.But, the example that recess 311 shown in Figure 2 forms in a variety of forms.For example, recess 311 may extend into outer side edges (shown in Fig. 3 (a)), also can be at the downward upper side edge 214 (shown in Fig. 3 (b)) that reaches of the state that extends to outer side edges 212, also may extend into lower side 215 (shown in Fig. 3 (c)), also may extend into upper side edge 214 and lower side 215 (shown in Fig. 3 (d)).And, downward upper side edge 214 and the lower side 215 (shown in Fig. 3 (e)) of reaching of state that recess 311 can be recessed to form on contact-making surface 201.As mentioned above, because recess 311 does not extend to inner side edge 213, therefore can prevent that motlten metal from flowing into recess 311 from casting mould 10.
But recess 311 also may extend into inner side edge 213 and outer side edges 212 (shown in Fig. 3 (f)).At this moment, recess 311 preferably has and can avoid the ladder of the degree that motlten metal flows out from casting mould 10 to outside poor.Therefore, be formed as extending to the limit of contact-making surface 201 according to the recess 311 on unsteady limit 200 of the present invention,, extend at least one limit in outer side edges 212, inner side edge 213, upper side edge 214 and lower side 215, and be formed as having in the situation of the area that fixed edge 100 contacts with unsteady limit 200 and can prevent the shape that motlten metal flows out to outside.
And recess 311 can be formed with multiple, and separate each other and be formed on (shown in Fig. 3 (g)) on contact-making surface 201.And as shown in fig. 1, recess 311 can be formed as rectangle, but also deformable is circular (shown in Fig. 3 (h)).But the shape of recess 311 is not limited to this, also deformable is the various shapes such as triangle, pentagon, hexagon.
