Abstract

The utility model relates to a pouring cup for pouring liquid metal in the lost foam casting. The pouring cup comprises an upper cup mouth and a lower cup base. The upper cup mouth is an inverted horn mouth with a big upper part and a small lower part. The middle part of the lower cup base is provided with a concave pouring basin. The pouring basin takes a shape of a basin with a big upper part and a small lower part. The lower cup base at the side of the pouring basin is provided with a through vertical short pouring gate. One side of the pouring basin is communicated with the upper part of one side of the vertical short pouring gate. A cup mouth axis line of the upper cup mouth is coaxial with a pouring basin axis line of the lower cup base. A lower port of the vertical short pouring gate of the lower cup base is provided with a filter screen plate. The pouring cup has a sufficient strength, a high temperature resistance performance and a certain capacity, so that the pouring cup is prevented from being impacted and burnt out and the liquid metal is prevented from overflowing when the liquid metal is poured into from a pouring ladle; a straight pouring gate system is effectively prevented from being impacted by the liquid metal and the defect of sand washing of castings is overcome; the lower port of the vertical short pouring gate of the lower cup seat is provided with the filter screen plate, so that the technical problem that in a lost foam casting process, the filter screen plate is inconvenient to install is solved and the defects of impurities in the castings and the like are overcome; and the manufacturing cost of the pouring cup is low.

Description

The cup that is used for casting of molten metal in the lost foam casting

Technical field

The utility model belongs to the lost foam casting technical field, is specifically related to be used in the lost foam casting cup of casting of molten metal.

Background technology

The cup of lost foam casting and sprue mainly contain two kinds of versions, and one is monoblock type, and promptly cup and sprue are made an integral body by refractory material, and its cost height can't be installed screen pack; Two is split type, and promptly cup is made by refractory material, also screen pack can't be installed.Lost foam casting is in casting process, the sprue part generally is made by the eps foam material, the sprue that the eps foam material is made runs into high-temperature liquid metal and all gasifies, thereby can't be fixed for the filter net sheet of filtering metal liquid impurity as sand casting, therefore foundry goods is easy to generate defectives such as assorted slag.On the other hand in when cast because the molten metal temperature is higher, wash out the sprue part easily, the sand washing defective of the die casting that causes disappearing, and molten metal is obstructed and defectives such as underpriming.

Summary of the invention

In order to solve the defective that existing cup and sprue version exist, the utility model provides the cup that is used for casting of molten metal in a kind of lost foam casting that improves structure.

The technical solution that realizes above-mentioned purpose is as follows:

The cup that is used for casting of molten metal in the lost foam casting comprises rim of a cup and following cup, and the described rim of a cup of going up rim of a cup is the up big and down small horn mouth that falls; Described down cup middle part is provided with a recessed pond of watering, and watering the pond is up big and down small peviform, and the following cup that waters pond one side is provided with a vertical short running channel that connects, and waters pond one side and is being communicated with vertical short running channel one upper lateral part; The rim of a cup axial line of last rim of a cup and following cup to water the pond axial line coaxial; The described vertical short running channel end opening place of cup down is provided with filtering net plate.

Be provided with a projection with the corresponding side that goes up rim of a cup of the upper port of the vertical short running channel of following cup, projection will vertically lack the upper port of running channel and be sealed.

Described rim of a cup and the following cup material gone up is casting with self-hardening sand or pottery.

Useful technique effect of the present utility model embodies in the following areas:

1, the utlity model has enough intensity, resistance to elevated temperatures and certain capacity, in case that molten metal washes out, burns out with molten metal when pouring into is excessive in pouring ladle; Wherein go up the slick and sly smooth transition of rim of a cup part, molten metal is not flowed into and produce resistance; Water the pond molten metal that flows into is played cushioning effect, effectively prevented impact, solved the sand washing defective of foundry goods the sprue system.The vertical short running channel end opening place of following cup is provided with filtering net plate can realize filtration to impurity in the molten metal; Solved the technical problem that filter net sheet is inconvenient to install in the lost foam casting process, realized effective filtration, solved foundry goods and be mingled with defectives such as matter molten metal;

2, it is all more convenient that the utility model is made use, and cost is low.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described by embodiment.

Embodiment:

Referring to Fig. 1, the cup that is used for casting of molten metal in the lost foam casting comprises rim of a cup 2 and following cup 1.The rim of a cup of last rim of a cup 2 is the up big and down small horn mouth that falls, and sees Fig. 2 and Fig. 3.Following cup 1 middle part is provided with a recessed pond of watering, and watering the pond is up big and down small peviform, waters on the following cup of pond one side and offers a vertical short running channel that connects, and waters pond one side and is being communicated with vertical short running channel one upper lateral part, sees Fig. 4 and Fig. 5.The rim of a cup axial line of last rim of a cup 2 and following cup 1 to water the pond axial line coaxial; The vertical short running channel end opening place of following cup 1 is provided with filtering net plate 3.Also can between last rim of a cup 2 and following cup 1, place filtering net plate as required.

Referring to Fig. 2 and Fig. 3, be provided with a projection with the corresponding side that goes up rim of a cup 2 in the top of the vertical short running channel of following cup, projection will vertically lack the upper port of running channel and be sealed.Last rim of a cup 2 and following cup 1 material are casting with printing sand or pottery certainly.

During cast, molten metal enters from last rim of a cup 2; The pond buffering area that waters at following cup 1 cushions, and passes through the vertical short running channel and the filtering net plate 3 of cup 1 down again, enters the sprue in the disappearance mould.
