Abstract
The utility model discloses a casting mould of gluing first board is penetrated to die casting machine, the drill die comprises a die body, the mould body includes mould and lower mould, be provided with between last mould and lower mould at least two with penetrate the die cavity of gluing first board and corresponding, be provided with a sprue on last mould, this sprue feeds through to the die cavity both sides through a cross gate, and the cross gate both ends are respectively through watering the bottom that feeds through to the die cavity both sides in one, die cavity upper end still is provided with the exhaust hole, waters to communicate to the die cavity side that to water the wall thickness that corresponds the face in, little in because, and it is balanced to form the cooling, reaches and solidifies the effect simultaneously, improves compactness, reduces the shrinkage porosite probability, adopt the technology after improving after, eliminated shrinkage cavity shrinkage porosite defect basically, installation back oil leak rate is 1 -1.5% only, has improved the yield greatly, gains obvious economic benefits.
Description
Technical field
The utility model relates to a kind of casting mould of die casting machine injection head plate.
Background technology
Injection head plate (as Fig. 1 to Fig. 3) is die casting machine key core parts, belong to pressurized oil braking high abrasion and seal, its cylinder part requires carrying 15-17kg oil pressure, high especially to foundry goods consistency requirements, material is QT500-7, casting structure irregular (became uneven), shrinkage cavity shrinkage porosity (as Fig. 4) is there is at through hole 2/3 place in actual production, leakage of oil is there is all in various degree or the seepage when machine operation some cycles after installation, foundry goods is caused to scrap, process yield only 68%, and repeatedly improve and all do not reach ideal effect.
As shown in Figure 5, Figure 6, molten iron enters die cavity from the front of die cavity to the casting mould of injection head plate, and casting pouring technique does not meet casting structure requirement, and the obverse wall thickness of ingate is large, and cooling velocity is slow, and cooling is the main cause causing Shrinkage cavity slowly.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of casting mould of die casting machine injection head plate.
The utility model solves the technical scheme that its technical problem adopts:
The casting mould of die casting machine injection head plate, comprise die ontology, described die ontology comprises upper die and lower die, at least two die cavities corresponding with injection head plate are provided with between upper die and lower die, patrix is provided with a sprue, this sprue is communicated to die cavity both sides by a cross gate, and cross gate two ends are communicated to the bottom of die cavity both sides respectively by an ingate, and described die cavity upper end is also provided with steam vent.
Described die cavity is configured with two, and two die cavities are symmetrical arranged, and described sprue and cross gate are arranged between two die cavities.
Some chills are provided with on rear side of described die cavity.
The beneficial effects of the utility model are: the casting mould of die casting machine injection head plate, comprise die ontology, described die ontology comprises upper die and lower die, at least two die cavities corresponding with injection head plate are provided with between upper die and lower die, patrix is provided with a sprue, this sprue is communicated to die cavity both sides by a cross gate, and cross gate two ends are communicated to the bottom of die cavity both sides respectively by an ingate, described die cavity upper end is also provided with steam vent, because ingate is communicated to die cavity side, the obverse wall thickness of ingate is little, form cooling balanced, reach coagulation result simultaneously, improve compactness, reduce shrinkage porosite probability, after adopting the technique after improving, essentially eliminate shrinkage porosity defect of contraction cavity, oil spill rate only 1-1.5% after installation, substantially increase yield rate, obtain obvious economic benefit.

Detailed description of the invention
With reference to Fig. 7 to Fig. 9, Fig. 7 to Fig. 9 is the structural representation of the utility model specific embodiment, as shown in the figure, the casting mould of die casting machine injection head plate, comprise die ontology, described die ontology comprises patrix 1 and counterdie 2, at least two die cavities 3 corresponding with injection head plate are provided with between patrix 1 and counterdie 2, patrix 1 is provided with a sprue 51, this sprue 51 is communicated to die cavity 3 both sides by a cross gate 52, and cross gate 52 two ends are communicated to the bottom of die cavity 3 both sides respectively by an ingate 53, described die cavity 3 upper end is also provided with steam vent 54.
As preferably, as shown in the figure, described die cavity 3 is configured with two, and two die cavities 3 are symmetrical arranged, and described sprue and cross gate 52 are arranged between two die cavities 3.
For balance cooling velocity, on rear side of described die cavity 3, be also provided with some chills 4.
The casting technique of die casting machine injection head plate, comprises the following steps:
Step one, make above-mentioned casting mould, in moulding box, produce patrix 1, counterdie 2, sprue 51, cross gate 52, ingate 53 and steam vent 54 by molding sand;
Step 2, molten iron, dissolve ferriferous raw material in a furnace;
Step 3, nodularization, pour into molten iron in casting ladle, and molten iron temperature adds nodulizer 1450 ± 20 DEG C time, and this nodulizer addition is the 1.23%-1.27% of molten steel quality, and described nodulizer is preferably rare earth magnesium nodularizer;
Step 4, molten steel preparation, add inovulant in molten iron, and the component of inovulant is the 0.6%-0.8% of molten steel quality;
Step 5, cast, pour molten iron into from sprue, pouring temperature 1350 ± 20 DEG C, 20 seconds durations of pouring, and added the inovulant accounting for molten steel quality proportion 0.15%-0.2% by the mode of current-following inoculation.
As preferably, described molding sand proportion is: fresh sand 15%, resin 1.2%, resin curing agent 50%, sand compression strength is greater than 8Mpa.
In the utility model, because ingate 53 is communicated to die cavity 3 side, the obverse wall thickness of ingate 53 is little, form cooling balanced, reach coagulation result simultaneously, and by using Instant Stream Inoculation Process, refinement matrix, improve compactness, reduce shrinkage porosite probability, after adopting the technique after improving, essentially eliminate shrinkage porosity defect of contraction cavity, oil spill rate only 1-1.5% after installation, substantially increases yield rate, obtains obvious economic benefit.
More than that better enforcement of the present utility model is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent distortion or replacement are all included in the application's claim limited range.
