Abstract

The utility model relates to a novel riser sprue iron casting gating system, wherein the ceramic filter (2) below of the gating system is provided with a riser sprue (3) incorporated by a riser and a sprue in the original prior art. The riser unit is removed in the gating system design provided by the utility model, and the sprue and the riser are incorporated into one unit; the casting is feed with the high-temperature molten iron from the sprue to reduce the riser size of conventional design; the process yield is improved, and the secondary melting of molten iron is reduced. The sand box area can be effectively utilized to reduce the amount of sand; the ceramic filter is arranged below the pouring cup to effectively prevent the impurities entering the molten iron.

Description

A kind of novel rising head sprue ironcasting running gate system

Technical field

The utility model relates to a kind of running gate system, is specifically related to a kind of novel rising head sprue ironcasting running gate system.

Background technology

Conventional design of gating system comprises: cup, sprue, cross gate, ingate, when foundry goods needs the molten iron feeding, generally design one again and carry out feeding to several rising heads, (as shown in Figure 1 and Figure 2), but the shortcoming of common process design is: product yield is lower, accessory system cup, sprue, cross gate, ingate, rising head have consumed a large amount of molten iron outside the foundry goods body, and the molten iron waste is serious, have increased the secondary fusion of too much molten iron; Sandbox need have enough vacant positions, to place rising head, has not only increased the size of sandbox, the increase that has brought sand using amount simultaneously; Owing to increased the rising head unit, operation difficulty and intensity have been increased relatively in the modeling process.

Summary of the invention

The utility model is in order to solve the problems of the technologies described above, and then a kind of novel rising head sprue ironcasting running gate system is provided, and it has cancelled the rising head unit in the pouring and riser systems design, sprue and rising head are merged into a unit.

The technical solution of the utility model: a kind of novel rising head sprue ironcasting running gate system, it comprises: cup 1, foam ceramic filter 2, rising head sprue 3, ingate 4, foundry goods 5, cup 1 below is provided with foam ceramic filter 2, the below of foam ceramic filter 2 is provided with the rising head sprue 3 that former sprue of the prior art and rising head are merged into a single whole, and rising head sprue 3 is connected with ingate 4, and ingate 4 is connected with foundry goods 5.The area of the rising head sprue 3 described in this device will be 1.2-3.5 times of technology sprue in the former running gate system, and this device also includes cross gate 6, and cross gate 6 can be determined according to the number of ingate.

The utility model compared with prior art has following beneficial effect: cancelled the rising head unit in the pouring and riser systems design of the present utility model, sprue and rising head are merged into a unit; Utilize the high temperature liquid iron of sprue that foundry goods is carried out feeding, can reduce the rising head volume in the conventional design; Improve product yield, reduced the secondary fusion of molten iron.Can effectively utilize the sandbox area, thereby reduce the consumption of molding sand; Foam ceramic filter is set below cup, can effectively avoids entering of impurity in the molten iron.
