Description

TECHNICAL FIELD

[0001] The utility model relates to foundry technology field, concretely relates to a circular ring feeding foundry mould. BACKGROUND

[0002] Casting is a processing technology method that the metal is melted and poured into the casting mold prepared in advance, and the required workpiece or blank is obtained after cooling and cleaning. Casting is an important and basic process method widely used in machine manufacturing. The process includes manufacturing casting mold, melting metal, pouring, cleaning, and taking out the castings after cooling and solidification. The raw materials for casting are widely sourced, the production cost is low, the process flexibility is large, and it is almost not limited by the size, shape and structure complexity of the parts.

[0003] Old pouring system: the pressure and speed are transmitted to the casting through the cake during pressure casting, but the cake is far away from the ingate, and the aluminum liquid flows into the casting through several bends after passing through the main runner and the annular runner. Disadvantage one: the mold is large, and the mold manufacturing cost is high; Disadvantage two: large pressure loss, the temperature of the aluminum liquid is high, the casting is not easy to be cold, and the energy consumption is large, and the qualified rate is low; Disadvantage three: the pressure of the cake is difficult to transmit to the product, the product is easy to produce pores and loose, the qualified rate is low, and the cost is high.

[0004] Therefore, we provide a circular ring feeding foundry mould. CONTENT OF THE UTILITY MODEL

[0005] The utility model discloses a circular ring feeding foundry mould, and the pressure loss is small during pressure casting, the temperature of the aluminum liquid is lower, the casting is not easy to be cold, the situation of pouring shortage is avoided, the energy consumption is small, and the qualified rate is high. The cake is located in the trough, the pressure of the cake is easy to transmit to the product, the product is not easy to produce pores and loose, the qualified rate of the product is high, and the cost can be reduced.

[0006] In order to realize the above-mentioned purpose, the technical scheme adopted by the utility model is:

[0007] A circular ring feeding foundry mould, including the casting and the cake, the casting one end is equipped with the ingate, the casting is close to the ingate one end still is equipped with the annular runner, the main runner and the trough, the main runner, the annular runner and the ingate are located between the casting and the trough, the trough is equipped with the cake in.

[0008] Through adopting the above-mentioned technical scheme, the pressure loss is small during pressure casting, the temperature of the aluminum liquid is lower, the casting is not easy to be cold, the situation of pouring shortage is avoided, the energy consumption is small, and the qualified rate is high. The cake is located in the trough, the pressure of the cake is easy to transmit to the product, the product is not easy to produce pores and loose, the qualified rate of the product is high, and the cost can be reduced.

[0009] Specific, the inner gate away from the end of the casting and ring flow channel side communication.

[0010] Specific, the ring flow channel away from the inner gate side and main flow channel one end communication.

[0011] Specific, the main flow channel away from the ring flow channel one end and the end wall of the trough communication.

[0012] The beneficial effects of the utility model:

[0013] The utility model discloses a circular ring feeding casting mould, and when die casting, the pressure loss is little, the temperature of aluminium water is lower, and the casting is not easy to cold isolate, avoids the situation of pouring shortage, has the advantages of small energy consumption, high qualified rate, the pressure of material cake is easy to transfer to product, and product is not easy to produce blowhole, loose, and product qualified rate is high, can also reduce cost simultaneously.
