Abstract
The invention relates to a structure for arranging a riser in a feeding channel of a differential casting. The shrinkage porosity of the casting occurs at the bottom of the through hole of the casting, the hole end is far away from the shrinkage porosity part, the through hole is changed into a solid state, a riser is arranged outside, and a heating block is arranged in the riser, so that the shrinkage porosity position of the differential can obtain full-mouth feeding molten iron from a feeding channel, and the compactness of the differential casting is uniformly improved.
Description
Technical Field
The casting process of the differential in the casting industry breaks through the technical measures of the feeding channel.
Background
The product of German Gikaien company, such as a differential casting with model number 10388056, is similar to a disc-shaped disc, the middle part of the differential casting is provided with a through hole, when the conventional casting process is carried out, the defect of shrinkage cavity (loose) appears around the middle part of the disc, if a feeding head is placed, the opening of the casting is far away from the shrinkage cavity part, and the casting cannot be used as a feeding channel.
Disclosure of Invention
The invention aims to establish a feeding channel to feed a shrinkage part.
The technical scheme of the invention is as follows: the middle part of the casting is changed into a solid through hole, the casting is used as a feeding channel, a feeding head is arranged outside the feeding channel, in order to make up for the larger distance of the feeding channel, a heating block is arranged in the feeding head, and the cooling speed of molten iron of the feeding head is further slowed down than that of the feeding part, so that feeding is successful.
After the feeding process scheme is set according to the scheme, the shrinkage porosity phenomenon does not occur at the position close to the center of the differential in production, and the casting is compact without shrinkage cavity.

FIG. 1 is a cross-sectional view of a differential internal riser location.
Wherein: 1. differential shell, 2, solid position instead of hollow, 3, feeding head, 4, heating block, 5, shrinkage porosity generating part
Detailed Description
A through hole in the middle of a differential shell 1 is changed into a solid channel, as shown in a position 2 in figure 1, a feeding head 3 is arranged above the solid channel 2, and a heating block 4 is arranged in the feeding head 3.
Claims (1)
1. The utility model provides a differential mechanism foundry goods is got through feeding passageway and is set up structure of rising head, characterized by: the through hole is changed into a solid in the middle of the differential casting, a riser is arranged outside the hole, and a heating block is arranged in the riser.
