Technical Field
The invention relates to the technical field of die-casting molds, in particular to an aluminum casting die-casting mold.
Background
Pressure casting is a special casting method which is developed faster in the modern metal processing technology and has less cutting and no cutting. The method is a process of filling a casting mold with molten metal at high pressure and high speed, and crystallizing and solidifying the molten metal at high pressure to form a casting. The pressure casting method has the advantages of high production efficiency, simple process, high tolerance grade of castings, good surface roughness, high mechanical strength, capability of saving a large number of machining processes and equipment, raw material saving and the like, so the method becomes an important component in the casting industry of China.
The die casting process is a process of organically combining and comprehensively using three major elements of a die casting machine, a die casting mold and an alloy. The process of filling the cavity with metal during die casting is a process of unifying technological factors such as pressure, speed, temperature, time and the like. Meanwhile, the process factors influence each other, restrict each other and complement each other. Only by properly selecting and adjusting these factors to be in harmony, the desired results can be achieved.
The die casting mold is one of the most important devices for implementing the die casting process, and the gating system is one of the most important structures in the die casting mold. The selection of the liquid inlet for filling the casting system into the mold cavity is highly regarded at the beginning of the design of the die casting mold. The mould all has the weak department of shaping when die-casting shaping, needs more metal liquid to fill, consequently need set up the inlet in weak department and just can guarantee that the product of pouring out meets the requirements. However, the die-casting die generally only has one pouring gate, and only one of a plurality of weak positions can be selected as a liquid inlet, so that the technical problem which needs to be solved by the invention is how to optimally design a pouring system of the die-casting die to ensure the quality of two forming weak positions which are far away from each other on a casting.

The technical scheme is as follows: the utility model provides an aluminum casting die, includes public template, public mould benevolence, cavity board and cavity mould benevolence, public mould benevolence and cavity mould benevolence form after the mould compound die and are used for fashioned die cavity, be provided with the gating system in the cavity board, the gating system includes that main runner, horizontal runner and a plurality of divide water, public template side and gating system homonymy department are provided with circular mold insert, be provided with the ingate that a plurality of goes on filling to the weak department of foundry goods on the public template, divide the metal of watering to flow in through the ingate, be provided with the slider on the public template, be fixed with the fixed column of stereotyping to the foundry goods hole on the slider.
Preferably, the cross section of the branch pouring channel is an inverted isosceles trapezoid, and the cross section area from the inlet to the tail end of the branch pouring channel is gradually reduced.
Preferably, a slag collecting ladle is arranged on the side, different from the side of the pouring system, of the male template, and the bottom of the slag collecting ladle is connected with an exhaust groove.
Preferably, the straight line of the fixed column in the length direction is perpendicular to the straight line of the cross gate in the length direction.
Preferably, the slider is internally provided with a heat conducting member.
The invention realizes the following beneficial effects:
according to the invention, the plurality of branch runners are arranged in the male template, so that molten metal flowing in the transverse runner enters the cavity through the branch runners, the metal in the branch runners flows into other casting weak parts through the plurality of ingates, the weak parts of the castings are synchronously filled, the shrinkage of the castings is prevented in the die-casting process, and the overall quality of the castings is improved.
