Description
Technical field
The present invention relates to have the casting forming mould of built-in type core.
Background technology
In the past,, metal formed products carried out such casting forming when being carried out contour forming: motlten metal is expelled to mould inside forms.In die casting machine, but through behind the injection molded formed products, dynamic model being left from fixed die, thereby but fixed die separate at divisional plane with dynamic model and become the state that can take out formed products.
At this moment; From needs to divisional plane side-pulling formed products; Even considered that being shaped as of formed products divisional plane also can't pull out under the situation of shape of formed products, use the built-in type core to wait to be shaped this formed products (with reference to patent documentation 1 (japanese kokai publication hei 7-16844 communique) and patent documentation 2 (TOHKEMY 2001-212850 communique)) sometimes.
When adopting such built-in type core to carry out casting forming; At first, the built-in type core is positioned at the inner precalculated position of fixed die, subsequently; But fixed die is aimed at dynamic model and after carrying out matched moulds, motlten metal is expelled in the inner die cavity of mould carries out casting forming.After the shaping, but dynamic model is separated with fixed die and carry out die sinking.
When carrying out die sinking, built-in type core and formed products are together extracted out from fixed die, thereby but together separate with fixed die with dynamic model.Thus, can from finishing die, take out formed products and built-in type core (with reference to patent documentation 2).
Like this, but in order when dynamic model moves, the built-in type core to be extracted out from fixed die is inner, the built-in type core extends with the mode parallel with the extraction direction of built-in type core with the contact-making surface of the location division of fixed die inside.
Summary of the invention
The technology that the casting forming that adopts the built-in type core is all the time in the field of the casting forming that adopts non-ferrous metal material such as aluminium to be carried out.Compare with the inner location division of the built-in type core that is made up of ferrous material and fixed die on every side thereof etc., the hardness of such non-ferrous metal materials such as aluminium is little.Therefore, even be formed on the hard edges that produces when being shaped, can when die sinking, not make built-in type core and location division equivalent damage by the hard edges owing to non-ferrous metal material in the gap of fixed die and built-in type core yet.
But under the situation of iron-based parts as formed products of casting forming hard, the hardness of the hard edges of the built-in type core that uses as the built-in type core and the hardness of fixed die main body and ferrous material is approaching.Therefore; Since injection during motlten metal the contact-making surface at the inner location division of fixed die and built-in type core produce hard edges, thereby might the built-in type core collude and be suspended on this hard edges and the location division of fixed die inside and the contact-making surface of built-in type core are sustained damage.
In addition, as stated, if the contact-making surface of the inner location division of fixed die and built-in type core produces damage, so might be from the formed products after fixed die inner extraction built-in type core and the injection chimeric with it.
And even the damage that on the contact-making surface of the inner location division of fixed die and built-in type core, produces is repaired with modes such as grinding a little, also can damage with regard to deepening owing to whenever injecting needs the replacing finishing die, has the problem that shortens die life.
And spended time might can't satisfy time production cycle for the damage of repairing inner location division of fixed die and built-in type core.The production line that perhaps, might be used to repair stops.
The object of the present invention is to provide such casting forming mould:, also can under the situation of not damaging the built-in type core, extract the built-in type core swimmingly out even on the contact-making surface of the inner location division of built-in type core and fixed die, produce the hard hard edges of iron system.
The casting forming mould of first aspect present invention is to be used for the casting forming mould of casting forming iron-based parts.But the casting forming mould is equipped with fixed die dynamic model, built-in type core and a plurality of location division.Fixed die has first recess.First recess forms the part of the die cavity corresponding with the outer shape of formed products.Moveable die has second recess.Second recess forms another part of die cavity.But dynamic model can be to moving back and forth near the direction of fixed die and the direction of leaving fixed die.The built-in type core is configured in the inside of first recess of fixed die.Behind casting forming, but when dynamic model leaves fixed die, but the built-in type core together leaves fixed die with the state that is clipped in the formed products with dynamic model.A plurality of location divisions contact with the built-in type core, so that in fixed die inside the built-in type core is positioned.The contact-making surface that the location division contacts with the built-in type core tilts with respect to the direction that the built-in type core is extracted out from fixed die, and tilts to the direction of the appearance and size that increases the built-in type core.
At this; Because the contact-making surface that the inner location division of fixed die contacts with the built-in type core tilts with respect to the direction that said built-in type core is extracted out from fixed die; And tilt to the direction of the appearance and size that increases said built-in type core, therefore, even produce the hard hard edges that iron is at the contact-making surface of built-in type core and location division; Also can under the situation of not damaging the built-in type core, extract the built-in type core swimmingly out, thereby productivity ratio improves.
The casting forming mould of second aspect present invention forms, and in the casting forming mould of first aspect, a plurality of location divisions are made up of a plurality of embedded blocks.A plurality of embedded block loading and unloading are installed on fixed die freely.A plurality of embedded blocks have at least one contact-making surface respectively.
At this, a plurality of location divisions are made up of a plurality of embedded blocks that loading and unloading are installed on fixed die freely, and a plurality of embedded blocks have at least one contact-making surface respectively.Like this, owing to utilize the contact-making surface of embedded block that the built-in type core is positioned, therefore, even under the situation that has produced wearing and tearing or damage, get final product owing to only change embedded block, thereby repairing and maintenances etc. is with low cost.
The casting forming mould of third aspect present invention forms, and in the casting forming mould of second aspect, contact-making surface has cross one another first contact-making surface and second contact-making surface.First contact-making surface and second contact-making surface tilt with respect to the direction that the built-in type core is extracted out from fixed die, and tilt to the direction of the appearance and size that increases the built-in type core respectively.
At this; Contact-making surface has cross one another first contact-making surface and second contact-making surface; First contact-making surface and second contact-making surface tilt with respect to the direction that the built-in type core is extracted out from fixed die, and tilt to the direction of the appearance and size that increases the built-in type core respectively, therefore; Each embedded block has two contact-making surfaces, thereby makes the adjustment time decreased of change during embedded block through utilizing an embedded block that the two sides is positioned.In addition, thus, compare, also reduced, therefore can reduce the change time because number is installed with the situation that embedded block all is set individually.And, can the built-in type core be positioned at the precalculated position exactly.
The casting forming mould of fourth aspect present invention forms, and in the casting forming mould of second aspect, embedded block is by the made harder than fixed die.
At this; Because embedded block is by the made harder than fixed die, therefore, though make the most of of fixed die or all be can increase on the words cost of hard material; But through making embedded block use high hardness material as different objects, thereby manufacturing etc. is with low cost.And, can prolong life-span of embedded block.

The specific embodiment
Below, with reference to accompanying drawing the casting forming mould 2 as the embodiment of casting forming mould of the present invention is described with the casting forming device 1 that possesses this casting forming mould 2.
< structure of casting forming device 1 >
Casting forming device 1 shown in Figure 1 (below, be called " building mortion 1 ") be the building mortion of casting forming iron-based parts.This building mortion 1 is shaped as the movable scroll of the for example screw compressor of iron-based parts, that is, like Fig. 8～shown in Figure 10, this building mortion 1 shaping scroll element 50, this scroll element 50 has: scroll part 51; Be formed at the tabular end plate 52 of the root side of scroll part 51; And the columned boss 53 of the opposition side that is formed at scroll part 51 on the end plate 52.
In this building mortion 1, semi-molten or semi-solid metal material through utilizing material filling machine structure 6 to exert pressure with iron system are that semi-molten/semi-solid metal material C is filled into finishing die 2 inside, thus can casting forming scroll element 50.
Behind shaping scroll element 50, but but a dynamic model 11 that constitutes finishing die 2 drive at dynamic model and slide on the platform 8 and leave another fixed die 12 (with reference to Figure 16).Then, but utilize push rod driving mechanism 7 that scrollwork is pushed into dynamic model 11 inside with push rod 3 and another push rod 9, thereby but scroll element 50 is taken out (with reference to Figure 17) with the state that clips built-in type core 5 from dynamic model 11 inside.
Below, explain in further detail that in sundry item finishing die 2 and scrollwork are with push rod 3.
< structure of casting forming mould 2 >
As shown in Figure 1, finishing die 2 has: but but drive the dynamic model 11 that platform 8 moves back and forth along dynamic model; But be fixed on dynamic model and drive the fixed die 12 on the platform 8; Built-in type core 5; And embedded block 14.
As shown in Figure 1, but dynamic model 11 has in being used for forming the die cavity 13 of scroll element 50: as scroll groove 13a second recess of the present invention, that be used for forming scroll part 51; And the tabular groove 13b that is used for forming end plate 52.
As shown in Figure 1, fixed die 12 has the cylindrical recess 13c that is used for forming columned boss 53 in being used for forming the die cavity 13 of scroll element 50.And, the insertion recess 13e that fixed die 12 has the cross gate groove 13d that is used for forming cross gate 54 and supplies built-in type core 5 to insert.
At this, cylindrical recess 13c, cross gate groove 13d and insertion recess 13e are corresponding with first recess of the present invention.
As shown in Figure 2, in the fixed die 12 of this embodiment, Outboard Sections 12a and inside part 12b can be cut apart.Because inside part 12b contacts with the semi-molten/semi-solid metal M of high heat, so inside part 12b is by the high made of hear resistance.Moreover, the Outboard Sections 12a of fixed die 12 and inside part 12b are become one.
As shown in Figure 1, but dynamic model 11 is fixed in movable platen 21, and drive on the platform 8 to moving back and forth near the direction of fixed die 12 and the direction of leaving fixed die 12 with coexist movable mould of movable platen 21 1.Fixed die 12 is fixed in stationary platen 22, and static on platform 8.
Built-in type core 5 is configured in die cavity 13 inside; So that form cross gate 54; This cross gate 54 is to be used for semi-molten or semi-solid metal material are filled into the stream in the die cavity 13, but said die cavity 13 forms, is the casting space of the shape of scroll element 50 when dynamic model 11 combines with fixed die 12.
Built-in type core 5 is configured between die cavity 13 and the cross gate 54, and loading and unloading are installed on fixed die 12 freely.That is, the left from Fig. 1 is to built-in type core 5 is inserted in fixed die 12.
Built-in type core 5 is configured between die cavity 13 and the cross gate 54; So that form cross gate 54; This cross gate 54 is such streams: be used for from plate part be on the end plate 52, be extruded with the second surface 52b of opposition side that ledge is the first surface 52a of scroll part 51, fill semi-molten or semi-solid metal to the thickness of slab direction of end plate 52.
Built-in type core 5 is configured in the inside of the insertion recess 13e of fixed die 12, but at dynamic model behind the casting forming 11 when fixed die 12 leaves, but built-in type core 5 together leaves fixed die 12 with the state that is clipped in the scroll element 50 with dynamic model 11.
The groove 5c of the semi-circular cross-section of built-in type core 5 forms the part of cylindrical recess 13c of the fixed die 12 of Fig. 2～shown in Figure 3, so that form columned boss 53 shown in Figure 1.
Embedded block 14 is the pair of right and left location divisions that contact with built-in type core 5, so that in fixed die 12 inside built-in type core 5 is positioned.A pair of embedded block 14 is that the cross section is the prism of L word shape, and it has the first contact-making surface 14a and the second contact-making surface 14b that contacts with built-in type core 5.The width of the interval of a pair of embedded block 14 and built-in type core 5 is identical or at this more than width, so that can support the overall width of built-in type core 5.
Embedded block 14 shown in Figure 2 and the built-in type core 5 contacted first contact-making surface 5a that extend longitudinally, 14a and the second contact-making surface 5b, 14b tilt with respect to the direction that built-in type core 5 is extracted out from fixed die 12 (direction of the side nearby vertical with paper among Fig. 2), and tilt (with reference to Fig. 4～Fig. 7) to the direction of the appearance and size that increases built-in type core 5.
For example; As shown in Figure 4; (this is because when the angle of inclination is spent less than 0.5, can't obtain effect of the present invention fully to the first contact-making surface 5a that extends longitudinally of built-in type core 5 to the extraction direction D of built-in type core 5 cant angle theta 1 (0.5 degree～5 is spent, is preferably about 2 degree); When spending greater than 5, the built-in type core might fall).In addition, therewith accordingly, the contact-making surface 14a that extends longitudinally of embedded block 14 also tilts to same direction, so that can contact with the first contact-making surface 5a face of built-in type core 5.On the other hand; As shown in Figure 5; Built-in type core 5 (this is because when the angle of inclination is spent less than 0.5, can't obtain effect of the present invention fully to the extraction direction D of built-in type core 5 cant angle theta 2 (0.5 degree～5 degree, be preferably about 2 degree) along the second contact-making surface 5b of horizontal expansion; When spending greater than 5, the built-in type core might fall).In addition, therewith accordingly, the contact-making surface 14b along horizontal expansion of embedded block 14 also tilts to same direction, so that can contact with the second contact-making surface 5b face of built-in type core 5.
Thus; Even produce the hard hard edges of iron system at the built-in type core 5 and the contact-making surface of location division (for example embedded block); Because built-in type core 5 is conical by its shape with embedded block 14, thereby, make clearance t 1 expand the t2 more much bigger to than t1 through pull built-in type core 5 like Fig. 6～shown in Figure 7; Therefore; Embedded block 14 and the built-in type core 5 contacted first contact-making surface 5a that extend longitudinally, 14a and along the second contact-making surface 5b, the 14b of horizontal expansion be not easy because of hard edges impaired, and, can further not form new damage owing to the damage that is produced yet.
Moreover the built-in type core 5 of this embodiment is provided with the projection 17 of taper at the lower surface of Fig. 2 and built-in type core 5 shown in Figure 5.But the projection 17 through this taper contacts with the projection 18 (with reference to Fig. 1) of dynamic model 11, thereby built-in type core 5 is upwards boosted when matched moulds.
Because embedded block 14 is installed on fixed die 12 freely through loading and unloading such as screws, so not dismantle fixed die 12 be replaceable embedded block 14.
Embedded block 14 is by the made harder than fixed die 12.For example, when fixed die 12 adopted perhardened steels etc. as die steel, embedded block 14 adopted the mould steel harder than perhardened steel etc.Therefore, the life-span of embedded block 14 prolongs.
< scrollwork is with the structure of push rod 3 >
Scrollwork shown in Figure 1 is installed on push rod driving mechanism 7 with push rod 3, but and can pass the through hole 15 that is formed at dynamic model 11 and haunt at the end of the scroll groove 13a of die cavity 13.
Scrollwork pushes the terminal 51a of the scroll part 51 of scroll element 50 with push rod 3 after scroll element 50 is shaped, thereby but can from dynamic model 11, release scroll element 50.
< summary of casting forming method >
The scroll element 50 that in this embodiment, is shaped is movable scroll, and it has the boss 53 of column, and this boss 53 protrudes in the second surface 52b of opposition side of the first surface 52a that is extruded with scroll part 51 of end plate 52.Therefore; From the part of the boss 53 at the center that is arranged in end plate 52 semi-molten or semi-solid metal are filled into the die cavity 13 of the finishing die 2 of scroll element 50 through cross gate 54, said cross gate 54 is to be used for semi-molten or semi-solid metal are filled into the stream in the die cavity 13.
Moreover an end of the cross gate 54 after the shaping links to each other with boss 53, and the other end links to each other with residual 55 of the material of material filling machine structure 6 sides.Therefore, shown in figure 13, behind the scroll element 50 that from finishing die 2, takes out after being shaped, with cross gate 54 and residual 55 excision of material.
In addition, in order to remove the incrustation scale on the semi-molten/semi-solid metal material C surface of just from material filling machine structure 6, having flowed out, material filling machine structure 6 is not configured in the positive back of boss 53, but leaves the distance configuration of the amount that is equivalent to cross gate 54.Thus, from the incrustation scale that semi-molten/remove on semi-solid metal material C surface mainly accumulates in residual 55 of material, so the situation that incrustation scale is sneaked in the scroll element 50 tails off.
< step of casting forming method >
Below, with reference to Figure 11～Figure 18 the casting forming method of the building mortion 1 of employing embodiment is described.
At first, in original state shown in Figure 11, built-in type core 5 is inserted in and inserts among the recess 13e.Begin from this original state shown in Figure 11, shown in figure 12, but but dynamic model 11 is moved along dynamic model driving platform 8, thus but dynamic model 11 and fixed die 12 are linked and formation die cavity 13 (matched moulds process).
Then, shown in figure 13, semi-molten/semi-solid metal material C is put into (material injection process) in the material filling machine structure 6.
Then, shown in figure 14, utilize hydraulic pressure or air to press the plunger 6a of material filling machine structure 6 is moved, thereby exert pressure semi-molten/semi-solid metal material C is filled into finishing die 2 inside (filling process).At this moment, the semi-molten/semi-solid metal M that fills in the way is filled in the die cavity 13 through cross gate groove 13d.
Then, shown in figure 15, the filling of semi-molten/semi-solid metal M in whole die cavity 13 accomplished, afterwards, when solidifying when semi-molten/semi-solid metal M cooling, the scroll element 50 after the shaping is die cavity 13 inner shapings (fill and accomplish).Scroll element 50 after shaping cross gate 54 and the material residual 55 inner with being formed at cross gate groove 13d links to each other.
Then, shown in figure 16, but but make dynamic model 11 drive platform 8 to move along dynamic model, thus but make dynamic model 11 leave fixed die 12 and open finishing die 2 (die sinking process).At this moment, but built-in type core 5 to be clipped in state between scroll element 50 and the cross gate 54 to dynamic model 11 side shiftings.In addition, in this die sinking process, the plunger 6a of material filling machine structure 6 is pushed out a little, but so that the object that scroll element 50, cross gate 54 and built-in type core 5 is become one form leaves fixed die 12 easily to dynamic model 11 side shiftings.
Then, shown in figure 17, but through being driven, push rod driving mechanism 7 make scrollwork inner outstanding to the scroll groove 13a of dynamic model 11 with push rod 3, thus scrollwork is with the scroll part 51 of push rod 3 pushing scroll elements 50.In addition.But another push rod 9 is also outstanding from dynamic model 11 through the driving of push rod driving mechanism 7, thereby the part beyond the scrollwork of pushing formed products.Thus, but can residual 55 of scroll element 50, cross gate 54, material after being shaped and built-in type core 5 be become one the object that forms from dynamic model 11 inner release (push).In addition, in the time of release, plunger 6a turns back to initial position.
Then, shown in figure 18, the object (formed products taking-up process) that becomes one and form from inner residual 55 of scroll element 50, cross gate 54, material and the built-in type core 5 that takes out after being shaped of finishing die 2.Built-in type core 5 is chimeric with scroll element 50 and cross gate 54.At this moment, scrollwork turns back to the original state among Figure 11 with push rod 3 and another push rod 9.
Scroll element 50 after the shaping partly is cut off in the boundary of cross gate 54 with boss 53, thereby separates with cross gate 54 and residual 55 of material.Meanwhile, being clipped in scroll element 50 also is able to separate with built-in type core 5 between the cross gate 54.
About to the last fine finishining of scroll element 50, implement Surface Finishing through machining, thereby can be finish-machined to the desired size of completion article and the surface roughness of scroll element 50.

In built-in type core in the past and since with the gap of embedded block be constant, therefore, when sustaining damage, this damage again can mold damage and on the pull direction, produce the linearly damage of shape.But; In this embodiment; Like Fig. 2 and Fig. 4～shown in Figure 7; Embedded block 14 and the built-in type core 5 contacted first contact-making surface 5a that extend longitudinally, 14a and the second contact-making surface 5b, 14b tilt with respect to the direction that built-in type core 5 is extracted out from fixed die 12 (direction of the side nearby vertical with paper among Fig. 2), and tilt to the direction of the appearance and size that increases built-in type core 5.
Thus; Like Fig. 6～shown in Figure 7; Make gap enlargement through pull built-in type core 5, therefore, produce damage because of hard edges at embedded block 14 and the built-in type core 5 contacted first contact-making surface 5a that extend longitudinally, 14a with along last being not easy of the second contact-making surface 5b, 14b of horizontal expansion; And, can further not form new damage owing to the damage that is produced yet.
Consequently, can swimmingly built-in type core 5 be extracted out from fixed die 12 after the shaping, can't be from fixed die 12 unfavorable condition such as extraction be able to eliminate.In addition, owing to can suppress to produce damage because of hard edges makes embedded block 14 and contact-making surface 5a, 14a and 5b, the 14b of built-in type core 5, so built-in type core 5 prolongs with embedded block 14 and other die life.And, producing damage owing to can be suppressed at built-in type core 5 with embedded block 14, therefore can reduce significantly owing to repairing the number of times that damage stops production line, the productivity ratio of the formed products of scroll element 50 grades is improved.
