Abstract

The utility model discloses a cast joint spare die casting die mainly includes cover half, fixed die plate, movable mould board, hydro-cylinder, side and takes out slider, ejection mechanism and the gating system, be equipped with the vacuum exhaust system who comprises cover half vacuum plate and movable mould vacuum plate on cover half, the movable mould, be connected with the vacuum plate on gating system's the horizontal runner. The utility model discloses cast connector die casting die, the vacuum is bled and is just utilized the vacuum pump to discharge fast the gas in the mould die cavity from the overflow mouth of casting system, forms the negative pressure in the die cavity, makes the book gas as few as possible in aluminium liquid fills in the twinkling of an eye, obtains inside fine and close, the bright and clean good die casting in surface.

Description

Casting connector die casting

Technical field

The utility model relates to a kind of casting connector die casting.

Background technology

Die casting is to carry out the main technique equipment that die casting is produced, the quality of die casting comprises the requirement of dimensional accuracy, the requirement of interior quality, the requirement of surface quality, the interior quality of die casting, the temperature of surface quality during by aluminium liquid filling die cavity, pressure, the gas content decision, pressure when can the fine or not standard of the casting system design of mould be filled to die cavity to aluminium liquid exactly, temperature loss drops to minimum, aluminium liquid flow at high speed volume gas is minimum, thereby obtain high-quality die casting, original die casting is not owing to be with vacuum pumping system, cause the die casting inherent quality can not reach requirement, the inherent quality of die casting can have pore, rough, shortcomings such as visible spot are arranged.

The utility model content

The purpose of this utility model provides and a kind ofly makes the densification of die casting inherent quality, does not have pore, smooth surface, do not have the casting connector die casting of visible spot by vacuum pumping system.

The technical scheme that the utility model is adopted for achieving the above object is: casting connector die casting, comprise that mainly cover half, solid plate, dynamic model, moving platen, oil cylinder, side take out slide block, ejecting mechanism and running gate system, described cover half, dynamic model are provided with the vacuum pumping system of being made up of cover half evacuated panel and dynamic model evacuated panel, are connected with evacuated panel on the cross gate of described running gate system.

Described running gate system is made up of cross gate, ingate and overflow launder.

Described running gate system is provided with the branch flow cone.

Be connected with vavuum pump on the described cover half evacuated panel.

The utility model casting connector die casting, vacuum suction is exactly to utilize vavuum pump from the overfall of casting system the gas the mold cavity to be discharged fast, in die cavity, form negative pressure, make volume gas the least possible in the moment filling of aluminium liquid, obtain the good die casting of interior solid, any surface finish.

Description of drawings

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is the utility model casting connector die casting dynamic model plane;

Fig. 2 is the utility model casting connector die casting cover half plane;

Fig. 3 is the utility model casting connector die casting vacuum pumping system structure chart.

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, this mould comprises dynamic model 1 in general structure, moving platen 2, cover half 11, solid plate 12, oil cylinder 7, side is taken out slide block 6, ejecting mechanism 8 and running gate system, dynamic model 1 is provided with dynamic model evacuated panel 3, cover half 11 is provided with cover half evacuated panel 13, this dynamic model evacuated panel 3 and cover half evacuated panel 13 are formed the vacuum pumping system of casting connector die casting, the running gate system of this mould is by cross gate 4, ingate 5 and overflow launder 10 are formed, on cross gate 4, directly be connected with evacuated panel 15, this evacuated panel 15 can directly deflate from cross gate 4, discharge the air in the die cavity, also be provided with branch flow cone 9 on the running gate system, referring to Fig. 3, the vacuum pumping system structure chart, on cover half evacuated panel 13, connect vavuum pump 14, from the overflow launder 10 of casting system the gas the mold cavity is discharged fast, in die cavity, form negative pressure by vavuum pump 14, make volume gas the least possible in the moment filling of aluminium liquid, obtain interior solid, the good die casting of any surface finish.
