Technical Field
The utility model relates to the technical field of casting production, in particular to a casting riser structure.
Background
In the casting production process, shrinkage holes and shrinkage porosity of the product casting are easily generated at the hot junction part due to the shrinkage effect in the liquid cooling process of the metal, so that the compactness of the product casting is affected, and the performance of the product casting is reduced.
In the prior art, the shrinkage defect of a product casting is usually overcome by adopting a riser sleeve, so that a sufficient feeding channel can be reserved between the riser sleeve and the product casting in the pouring and cooling processes, the riser sleeve often adopts a larger riser neck structure, and under the condition, the riser casting is removed from the product casting, so that the following two problems are easily caused:
firstly, the size of a product casting formed at the riser neck is larger, and the riser casting is not easy to detach from the product casting;
secondly, after the riser sleeve is broken and disassembled, a large concave-convex surface is easy to generate at the joint of the product casting and the riser neck, so that great difficulty is brought to the subsequent grinding of the product casting, and the production efficiency is seriously reduced.
For this purpose, the applicant has proposed the present application.

Detailed Description
The utility model is described in further detail below with reference to the attached drawings and detailed description:
referring to fig. 1-4, a riser structure for castings comprises a riser body 1, wherein the riser body 1 comprises a mounting groove body, a metal piece 2 matched with the castings is arranged at the mounting groove body, and a plurality of through holes 21 are formed in the metal piece 2.
As shown in fig. 2 and 4, the mounting groove body includes a first groove 31 and a second groove 32 which are mutually communicated, wherein the second groove 32 is annularly distributed on the riser body 1, and the first groove 31 is circumferentially distributed on the outer periphery of the second groove 32.
The number of the first grooves 31 may be specifically selected according to practical needs, for example, six, and uniformly and equidistantly distributed.
As one of the embodiments, the outer end of the riser body 1 includes an annular flat wall 11, the installation groove body is formed on the annular flat wall 11, the annular flat wall 11 can also be directly contacted with the casting in actual use, and when the metal piece 2 is installed on the installation groove body, the outer surface of the metal piece is flush with the annular flat wall 11.
In this embodiment, the metal piece 2 includes a main body portion 22 and a plurality of protruding heads 23 circumferentially distributed on the periphery of the main body portion 22, wherein the main body portion 22 is matched with a second groove 32, the protruding heads 23 are matched with a first groove 31, the shape and size of the second groove 32 are matched with those of the main body portion 22, and the positions, the number and the shape and the size of the protruding heads 23 are matched with those of the first groove 31.
In this embodiment, the metal member 2 is fixed to the riser body 1, and alternatively, the fixing means may be welding or fixing by a fastener. The metal member 2 may be made of iron.
