Detailed Description
The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to the attached drawings 1-4 in the specification, the point-to-point feeding structure for solving the casting shrinkage porosity of the embodiment comprises a casting 1, a casting hot joint 3 is arranged inside the casting 1, a riser 2 is fixedly arranged on the outer surface of the top end of the casting 1 above the casting hot joint 3, a top disc 4 is fixedly arranged at the top end inside the riser 2, an inner layer 5 is arranged on the inner wall of the riser 2, an outer layer 7 is arranged on the outer wall of the riser 2, and a heat insulation layer 6 is arranged between the inner layer 5 and the outer layer 7.
Furthermore, the bottom end of the riser 2 is communicated with the casting hot spot 3, the riser 2 is placed at the casting hot spot 3 by using a point-to-point feeding process, the feeding distance is shortened, and the hot spot can be effectively fed, for example, one riser 2 can be placed at each hot spot of a plurality of hot spots of the casting, so that each hot spot of the casting can be fully fed.
Furthermore, the shape of the top disc 4 is funnel-shaped, after molten metal enters the riser 2, the opening at the bottom end is small, heat dissipation is slow, and meanwhile, the inner wall of the riser 2 adopts the structure of the outer layer 7, the heat insulation layer 6 and the inner layer 5, so that the heat insulation effect of the riser 2 is improved.
