Abstract
The utility model discloses an aluminum alloy piston casting die with a small feeder head, which relates to the improvement to the metal mold casting mould of the blank gravitation of the aluminum alloy piston. The aluminum alloy piston casting die with the small feeder head is characterized in that the external side of the lower part of the feeder head is an inclined arc surface; that is to say, the outermost bus bar is an inclined straight line, and a pouring channel is connected with a pouring cup from the utmost upper end of the inclined arc surface on the lower part of the feeder head. Thus, under the condition that the flow path of the pouring channel is very short, when the aluminum alloy liquid is poured, the splashing phenomenon generated at the bottom of the feeder head can be effectively prevented. The injection mode of the metal liquid is changed, and the pouring channel can be provided with very small cross-sectional areas. Accordingly, the weight of the pouring feeder head is alleviated; the utilization rate of the raw material is enhanced; the slag shielding function is enhanced; the waste product rate is lowered; the feeding ability is enhanced, and the intrinsic quality of the blank can be enhanced.
Description
The utility model is the improvement to all-aluminium piston blank gravity metal die cast mould.
The casting of all-aluminium piston blank, the at present main gravity metal die cast method that adopts, its running gate system have gooseneck type, snakelike and knife-edge etc. several.The common issue with that these several systems exist is, the running channel long flow path, and cross-sectional area is big, and the rising head setting is bigger, causes dead head weight bigger, and the aluminum alloy materials utilization rate is low, and the energy and raw materials consumption increase; Because running channel is long, during cast,, reach the purpose that prevents that alloy liquid from splashing though alloy liquid mobile had certain cushioning effect, the alloy liquid temp loses bigger, causes the rising head temperature on the low side, and the feeding effect is not good enough, influences the piston blank inherent quality; Running channel adopts the rising pouring form, and during cast, alloy liquid enters die cavity from the bottom all the time, and die cavity top alloy liquid temp is on the low side, and thin-walled (young mouthful of the piston) part that is in die cavity top is difficult to moulding and ensures the quality of products, so generally the running channel cross-sectional area is all bigger.Like this, be unfavorable for pushing off the slag, easily form dreg defect, cause waste product.
The purpose of this utility model provides a kind of improved piston blank gravity metal die cast mould, to alleviate dead head weight, improves the blank inherent quality, reduces percent defective.
The utility model is achieved in that takes single rising head setting, and the rising head bottom outside be oblique cambered surface, and promptly the outermost bus is a skew lines, and running channel topmost glass joins with watering from oblique cambered surface.Like this, the rising head bottom is equivalent to the part of running channel, and good cushioning effect is played in the injection of alloy liquid.Under the very short situation of running channel flow process, also can prevent the splash phenomena that alloy liquid produces in the rising head bottom effectively.
Through above-mentioned improvement, shortened running channel length greatly, dwindled the cross-sectional area of running channel, rising head is provided with less, has therefore alleviated dead head weight greatly, has improved the utilization rate of aluminum alloy materials, has reduced the consumption of electric power, fuel and material; Because running channel shortens, alloy liquid flow process reduces, and has improved the temperature of alloy liquid in the rising head, has strengthened the feeding capacity of rising head, and the piston blank inherent quality is improved; Changed the rising pouring mode of original running channel, alloy liquid enters the position of die cavity, rising with liquid level in the die cavity raises, improved the thermograde of alloy liquid in the die cavity, under the much smaller situation of running channel cross-sectional area, foundry goods is easy-formation also, is beneficial to pushing off the slag, prevent that foundry goods from producing dreg defect, reduced percent defective.
The concrete structure of utility model is drawn by following embodiment and accompanying drawing.
Accompanying drawing Fig. 1 is the front view of the die cast mold halves that proposes of the utility model, and Fig. 2 is a vertical view.
Runner system is formed by watering cup (1), running channel (2) and rising head (3) etc.Alloy liquid injects from watering cup (1), through running channel (2), enters rising head (3) and die cavity (4).The outside, rising head (3) bottom and running channel ramp interface, under the very short situation of running channel, alloy liquid also can enter rising head (3) and die cavity (4) reposefully along the inclined-plane.Experiment shows rising head (3) bottom, running channel (2) and waters cup (1) rising head that outward side bus is in line the time, and percent defective is minimum, and effect is best.The angle α of outermost bus and vertical direction is to select 20 °-45 ° to be advisable, and angle is too small, and the inclined-plane is steep excessively, and cushioning effect weakens, and is excessive, can cause running channel long, inaccessible the utility model purpose.
Claims (3)
1, all-aluminium piston blank gravity metal die cast mould, its running and feeding system is formed by watering cup (1), running channel (2) and rising head (3), it is characterized in that:
A, the outside, said rising head (3) bottom are oblique cambered surface, and promptly the outermost bus is a skew lines.
B, said running channel (2) from rising head (3) tiltedly cambered surface topmost with water cup (1) and join.
2, as the said all-aluminium piston blank of claim 1 gravity metal die cast mould, it is characterized in that said rising head (3) bottom and running channel (2) outermost bus in line.
3, as claim 1 or 2 said all-aluminium piston blank gravity metal die cast moulds, the angle that it is characterized in that said straight line and vertical direction is 20 °-45 °.
