Background
The metal mold casting mold is mainly divided into a gravity casting mold and a pressure casting mold, wherein the gravity casting mold can be divided into a fixed casting mold and a tilting casting mold. The tilting pouring is a pouring process that the mould tilts on a tilting pouring machine to enable the molten metal contained in the pouring cup to gradually fill the cavity in the tilting process of the mould so as to obtain a casting. The tilting pouring has the advantages of stable mold filling, improvement of alloy utilization rate, reasonable solidification sequence and contribution to casting feeding. To improve production efficiency, the mold is typically a one-mold-multiple-cavity arrangement for smaller castings. The existing one-mold multi-cavity mold adopts a single-water storage tank multi-sprue pouring mode, and molten aluminum in a water storage tank of a pouring cup is filled into the mold through a water inlet corresponding to each cavity to fill the cavities and pour the cavities. Such molds often suffer from the following problems during production: firstly, how to determine that the molten metal added into the pouring cup meets the weight required by pouring, if the weight is less, the feeding capacity is insufficient, and if the weight is more, the phenomenon of fire running can occur; secondly, how to evenly distribute the molten metal in the pouring cup to each cavity so as to fully fill the casting and the casting head, thereby obtaining the qualified casting. In the actual production process, because the temperature deviation of each cavity, the thickness of the coating are different, the equipment is not stably operated and the like, the problems that the weight of the metal liquid obtained by each cavity is different, the product is scrapped and safety accidents occur frequently occur.

The sprue cup is provided with sprue runners with the number equal to that of the cavities. The water storage tanks are positioned on the pouring cup, and the number of the water storage tanks equal to that of the cavities is arranged in the pouring cup. When the liquid level of the molten metal in the water storage tank reaches the water quantity indicating line, the weight of the molten metal is exactly equal to the pouring weight required in the cavity and the casting head cavity. The water storage tank partition plate is arranged in the middle of the adjacent water storage tanks to form an independent water storage tank, and the water storage tank partition plate is provided with an equal opening and a water quantity indicating line which are connected with the adjacent water storage tanks. The number of the water storage tank clapboards is 1 less than that of the water storage tanks.
The design of the water quantity indicating line on the mold pouring cup ensures that the required metal liquid is accurately added, and the phenomenon that waste products are generated due to insufficient metal liquid or waste is generated due to excessive metal liquid is avoided; meanwhile, the upper equalizing port of the pouring cup ensures that the same amount of molten aluminum is evenly distributed to each water storage tank, and each cavity and the casting head cavity are ensured to obtain the same amount of proper molten metal. The split type pouring cup corresponds to each cavity independently, and an operator does not need to pour molten metal into different water storage tanks respectively; compared with an integral pouring cup without a water storage tank partition plate, the problem that the water amount distributed in each cavity is different is solved. The invention integrally accords with the principle of tilting casting, fully exerts the characteristics of the tilting casting, has the advantages of stable filling and high process outlet rate, can better ensure the product quality and improve the product percent of pass.

Detailed Description
In fig. 1 and 2, the present invention is a metal mold comprising an upper mold 1, a lower mold 2, and a pouring cup 11. The upper die 1 and the lower die 2 do relative motion up and down, and more than 2 die cavities 3 and a casting head cavity 4 connected with the die cavities 3 are arranged on the contact surface of the upper die 1 and the lower die 2. A water inlet 5 is formed on the outer side of the lower die casting head cavity, and a gas outlet 6 is formed on the outer side of the upper die casting head cavity. The pouring cup 11 is rigidly connected with the lower die 2, water storage tanks 12 with the same number as the cavities are arranged on the pouring cup, and the pouring cup is used for containing molten metal required by the cavities 3 and the casting head cavity 4 before the tilting starts; each water storage tank 12 is provided with a flow dividing port 7 connected with a water inlet, so that molten metal enters the casting head cavity 4 through the flow dividing port 7; a water storage tank partition plate 8 for separating the water storage tanks 12 is arranged between the water storage tanks 12, so that the weight of the metal liquid stored in each water storage tank 12 is equal; an equalizing port 10 for communicating the adjacent water storage tanks 12 is arranged on the side, far away from the flow dividing port, of the water storage tank partition plate 8, so that molten metal in the water storage tanks 12 is injected into the adjacent water storage tanks 12 through the equalizing port 10; the upper edge of the equalizing port 10 is provided with a water quantity indicating line 9 for indicating the adding amount of the molten metal, and when the liquid level of the molten metal in each water storage tank 12 reaches the water quantity indicating line 9, the weight of the molten metal meets the weight required by pouring.
The design of the water quantity indicating line 9 on the pouring cup of the die ensures that the required metal liquid is accurately added, and the phenomenon that waste products are generated due to insufficient metal liquid or waste is generated due to excessive metal liquid is avoided; meanwhile, the upper equalizing port of the pouring cup ensures that the same amount of molten aluminum is evenly distributed to each water storage tank, and each cavity and the casting head cavity are ensured to obtain the same amount of proper molten metal. Compared with an integral pouring cup without a water storage tank partition plate, the problem that the water amount distributed in each cavity is different is solved. During production, the die is installed on the tilting casting machine, and the installation is guaranteed to be firm in place.
When pouring, the mould is returned to the state shown in figure 3, the upper mould and the lower mould are closed, and the molten metal is poured into any one of the water storage tanks 12 until the liquid level height of the molten metal in all the water storage tanks 12 reaches the water quantity indicating line 9. The rotating switch of the tilting casting machine is pressed to drive the whole die to rotate, the liquid level is collected at the root of the shunting port 7 when the die just starts to rotate, and no molten metal is injected into the die cavity at the moment. When the mould rotation alpha reaches the state shown in figure 4, the liquid level of the molten metal reaches the root part of the branch opening 7 and simultaneously descends below the uniform opening 10, so that the water storage tanks 12 are separated from each other and the molten metal is not exchanged. The mould continues to rotate and the molten metal begins to be injected into the casting head cavity 4 through the water inlet 5 and then into the cavity 3, and simultaneously air is discharged from the air outlet 6. When the mould rotates 90 degrees to reach the state shown in figure 5, the molten metal is completely injected into the cavity 3 and the casting head cavity 4, the solidification process is started, and the molten metal in the casting head cavity 4 is used for feeding the casting in the cavity 3 so as to obtain a high-quality casting. And after solidification, the casting machine is turned backwards to drive the mold to return to 0 degree, the upper mold 1 is lifted upwards, and the castings in the cavities are taken out. The above process is repeated for continuous production.
