Abstract
The utility model provides an open riser which comprises a molding sand layer, a casting chamber which is arranged in the molding sand layer, and an open riser main body which is arranged in the molding sand layer and corresponds to the top of the casting chamber. A heating device is arranged in the open riser main body. The utility model has the advantages that the temperature can be kept to be high, the feeding effect is improved, the quality of castings is improved and the defects of loosing and the like can be avoided.
Description
Technical field
The utility model relates to casting field, is specifically related to a kind of open riser that is used to cast.
Background technology
In the open riser feeding process of foundry goods, the open riser top is directly to contact with atmosphere, radiating rate is very fast, and foundry goods is in molding sand, and its radiating rate is slower than rising head, for preventing rising head fast than foundry goods cooling, the diffusing exothermic mixture that spreads at the open riser top, have certain insulation effect, but exothermic mixture is one deck, its heat insulation effect is poor.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of open riser, can keep higher temperature, improves the feeding effect, promotes the quality of foundry goods, prevents generation of defects such as loose.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: a kind of open riser, comprise the molding sand layer, be located at the interior foundry goods chamber of molding sand layer, be located at the open riser main body corresponding in the molding sand layer, be provided with heater in the described open riser main body with the foundry goods top of chamber.
As preferably, described heater is a heating rod.Simple in structure, heat effective.
Beneficial effect:
The utility model adopts technique scheme that a kind of open riser is provided, and can keep higher temperature, improves the feeding effect, promotes the quality of foundry goods, prevents generation of defects such as loose.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of open riser comprises molding sand layer 1, is located at foundry goods chamber 2 in the molding sand layer 1, is located at the open riser main body 3 corresponding with 2 tops, foundry goods chamber in the molding sand layer 1, is provided with heater 4 in the described open riser main body 3.Described heater 4 is a heating rod.Loose and be provided with heating bar when spreading exothermic mixture in open riser main body 3 tops, this heating bar connects power supply, has constant function for temperature, make the molten metal in open riser main body 3 continue the higher temperature of maintenance, so just, can form consecutive solidification, improve the feeding effect of open riser, promote the quality of foundry goods, prevent generation of defects such as loose.
