Abstract

The utility model discloses a riser neck of dish type. The utility model forms a disk shape, a disk body and a disk bottom can be made into various shaped, and the central of the disk bottom is provided with a through hole. The utility model adopts conventional fireproof material, heat insulating fireproof material, heating fireproof material, etc.; the riser neck can be made to be short, the feeding effect of the riser can be strengthened, the cross sectional area of the riser neck can be further reduced, the position of the fracture surface of the riser can be effectively controlled, the riser neck can be easily fractured and cut, and the cleaning and grinding workload can be reduced, and the possibility that the sand inclusion of a cast caused by that the intensity of a sand mold riser neck is insufficient can be avoided. The utility model has a wide market space and is particularly suitable for the self hardening sand process.

Description

Riser neck of dish type

The utility model relates to metal casting.

Riser neck is the feeding passage between rising head body and foundry goods, in the prior art, people attempt to adopt the method that shortens riser distance to improve the feeding capacity of rising head, but because of the limited riser neck that must keep certain-length of sand mold intensity, simultaneously, for guaranteeing to obtain perfect foundry goods profile, the boss of general design certain altitude is placed rising head, in case strike when breaking rising head, the foundry goods body is destroyed, makes follow-up polishing workload bigger like this.

The purpose of this utility model is to provide a kind of and makes the feeding capacity of rising head strong, frangibility, easily cutting, and the follow-up polishing of foundry goods is Riser neck of dish type simply and easily.

Technical solution of the present utility model is:

A kind of Riser neck of dish type is the plate shape, and the center of trying to get to the heart of a matter has through hole.

Disk body can be made into different shape with trying to get to the heart of a matter.Integral body can adopt common refractory, thermal insulation fire-resistant material, heating refractory material etc.

The utility model adopts common refractory, the thermal insulation fire-resistant material, the heating refractory material, riser neck can be done very short, after molten metal is full of rising head, the caloric receptivity at Riser neck of dish type place is much smaller than the caloric receptivity at common sand mold riser neck place, thereby prolonged the setting time of riser neck place molten metal, strengthened the feeding effect of rising head, the sectional area of riser neck can be further dwindled, the position of the rising head plane of disruption can be effectively controlled, frangibility, easily cutting, reduce cleaning polishing workload, save abrasive material, and can avoid the sand mold riser neck to cause the possibility of foundry goods " burning into sand " because of undercapacity, have the vast market space, be specially adapted to self-hardening sand technology.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the configuration diagram of an embodiment of the utility model.

Fig. 2 is the application state figure of Fig. 1 embodiment.

A kind of Riser neck of dish type adopts common refractory or thermal insulation fire-resistant material, heating refractory material (example pottery, fire clay etc.), is the plate shape, comprises disk body 6, tries to get to the heart of a matter 1, and 1 the center of trying to get to the heart of a matter has through hole 2.Disk body 6 and try to get to the heart of a matter and 1 can be made into different shape.

During use, Riser neck of dish type is placed between casting mold 5 and the rising head body 3, also have sand mold 4 among Fig. 2.

Claims

1, a kind of Riser neck of dish type is characterized in that: be the plate shape, the center of trying to get to the heart of a matter has through hole.
