Abstract
The invention discloses an extrusion casting die, which comprises an upper template, a male die, a female die, a casting, bolts, a lower pressing head, a lower die seat and a pull rod, wherein the female die and the lower die seat are fastened through the bolts; the pull rod is arranged on the lower die seat in a penetrating way; the lower pressing head is arranged at one end of the pull rod; the female die is arranged on the outer side of the lower pressing head; the male die is arranged between the female die and the upper template; and the casting is arranged between the male die and the lower pressing head. By using the extrusion casting die, a casting product is relatively high in comprehensive performance, relatively high in precision, and relatively low in allowance and the surface of the casting product is relatively smooth.
Description
Technical field
The present invention relates to a kind of squeeze casting mould.
Background technology
Casting is both economical blank forming method, more can demonstrate its economy for complex-shaped part.Like the cylinder body of automobile engine, cylinder cap, propeller for vessels and the exquisite art work etc.In addition; The accessory size of casting and the accommodation of weight are very wide, and the kind of metal is restricted hardly, and part is when having the common mechanical performance; Also have combination properties such as wear-resisting, corrosion-resistant, shock-absorbing; This be other metal forming methods as forge, roll, weld, dash etc. do not accomplish that the blank part of therefore in machine-building, producing with casting method is still maximum so far on quantity and tonnage.But die casting is in forming process, because that fill at some position is imperfect, when owing to cast the position when serious; Just cause the shape of foundry goods not meet drawing requirement, simultaneously, because in press casting procedure; The contraction of foundry goods is bigger, thereby the stress that produces causes tearing of foundry goods, and; In the process of setting of foundry goods, because the metal undercompensation forms dead color, the erratic lockhole of shape.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of squeeze casting mould in order to solve the deficiency of prior art, and this mould makes foundry goods that comprehensive performance arranged, higher precision, surplus still less and brighter and cleaner surface.
Technical scheme: in order to realize above purpose, a kind of squeeze casting mould of the present invention, it comprises cope match-plate pattern, punch, die, foundry goods, bolt, push-down head; Die shoe and pull bar, described die and die shoe are through bolted, and pull bar is arranged on the die shoe; One end of pull bar is provided with push-down head; The outside of described push-down head is provided with die, and the middle of die and cope match-plate pattern is provided with punch, and the middle of described punch and push-down head is provided with foundry goods.
Described template, punch, die, foundry goods, push-down head, die shoe and pull bar are positioned on the same axis.
Described die shoe and pull bar are realized displacement through the mode that is threaded.
Beneficial effect: a kind of squeeze casting mould provided by the invention; Be through increasing extruding feeding instrument after type is filled in die casting; Fill type through common die casting; The extrusion casint feeding solving quality problems such as traditional die casting, evacuated die-casting process ubiquitous shrinkage cavity of technology and shrinkage porosite, and is eliminated various shrink defects.This squeeze casting mould makes cast product have comprehensive performance, higher precision, surplus still less and brighter and cleaner surface.
Description of drawings
Full sectional view of the present invention when Fig. 1 pours into mould for molten metal,
Partial sectional view of the present invention when Fig. 2 cools off for foundry goods.
The specific embodiment
Below in conjunction with accompanying drawing, further illustrate the present invention.
Shown in Figure 2 like Fig. 1, a kind of squeeze casting mould of the present invention, it comprises: cope match-plate pattern 1, punch 2, die 3, foundry goods 4, bolt 5, push-down head 6, die shoe 7 and pull bar 8.
Described die 2 is fastening through bolt 5 with die shoe 7; Pull bar 8 is arranged on the die shoe 7, and an end of pull bar 8 is provided with push-down head 6, and the outside of described push-down head 6 is provided with die 3; Die 3 is provided with punch 2 with the middle of cope match-plate pattern 1, and described punch 2 is provided with foundry goods 4 with the middle of push-down head 6.
Described template 1, punch 2, die 3, foundry goods 4, push-down head 6, die shoe 7 is positioned on the same axis with pull bar 8.
Described die shoe 7 is realized displacement with pull bar 8 through the mode that is threaded.
As shown in Figure 1, in liquid metals poured into die 3, punch 2 descended; Realization is exerted pressure to metal, and is when the step of punch 2 contacts with die 3, as shown in Figure 2; Die 3 receives the pressure of punch 2 and descends, and with the dwindling of distance between punch 2 and the die 3, realizes being equivalent to 6 pairs of molten metals pressurizations of push-down head through bolt 5; Thereby the pressure that makes punch 2 can evenly be delivered to each position of foundry goods 4; After treating foundry goods 4 coolings, pull bar 8 is pulled out foundry goods 4 through push-down head 6 from die 4, realized the demoulding.
A kind of squeeze casting mould of the present invention fills type through common die casting, and the extrusion casint feeding solving quality problems such as traditional die casting, evacuated die-casting process ubiquitous shrinkage cavity of technology and shrinkage porosite, and is eliminated various shrink defects.This squeeze casting mould makes cast product have comprehensive performance, higher precision, surplus still less and brighter and cleaner surface.
Above-mentioned embodiment only is explanation technical conceive of the present invention and characteristics, its objective is to let to be familiar with these those skilled in the art and can to understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalents that spirit has been done according to the present invention or modification all should be encompassed within protection scope of the present invention.
