In the casting mould, the cavity of the riser is a cavity for storing liquid metal, and the metal is supplied when the casting is formed, so that the functions of preventing shrinkage cavity, shrinkage porosity, exhausting and slag collection are achieved, and the main function of the riser is feeding. The nodular cast iron is divided into three stages of liquid shrinkage, graphite expansion and solid shrinkage in a solidification stage, and in the design of the current scheme, a riser is designed to be capable of completely supplementing the shrinkage in the liquid shrinkage stage so as to avoid the defects of shrinkage cavity on the appearance and shrinkage porosity in the casting; the riser design of most of the existing foundry supports is an independent riser design, namely, one riser feeds a hot junction of a product, and the design has the advantages of small riser thermal modulus, small feeding amount, large number of required risers, low product retention rate, difficulty in riser removal, more defects of the product produced by the design, high labor intensity of personnel and high cost.
Disclosure of Invention
The utility model provides a solve above-mentioned problem, provide one kind and can promote rising head thermal modulus, increase rising head feeding volume reduces rising head quantity, promotes the step stay rate of product and hangs down, reduces the sharing rising head model structure that the degree of difficulty was got rid of to the rising head.
The utility model discloses the technical scheme who takes:
a common riser model structure of a bracket for horizontal line production comprises a riser body, a riser base, a riser neck and a riser neck connecting section, wherein the riser body is a cylinder, the diameter of the section of one end of the riser body is smaller to form a small-diameter port, the diameter of the section of the other end of the riser body is larger to form a large-diameter port, the small-diameter port of the riser body is provided with a conical groove, the large-diameter port of the riser body is connected with the riser base, the riser neck is a trapezoidal cylinder, the trapezoidal section areas at the two ends of the riser neck are different in size, the riser neck is connected to the side surface of the riser body close to the large-diameter port through the riser neck connecting section, the riser neck connecting section is also a trapezoidal cylinder, the trapezoidal section areas at the two ends are different in size, the end with the larger section area of the riser neck connecting section is connected with the riser body, the end with the smaller section area of the riser neck connecting section, the end with the larger cross-sectional area of the riser neck is connected with a product, and the riser neck connecting sections are four groups in total and are connected to the riser body at different angles.
The included angle between the second group of the riser neck and the first group of the riser neck connecting section is 60 degrees, the included angle between the third group of the riser neck and the first group of the riser neck is 180 degrees, and the included angle between the fourth group of the riser neck and the first group of the riser neck is 240 degrees.
The riser base is a semi-sphere.
The utility model has the advantages that: the utility model uses four products to share one riser, which has large hot mold number and strong feeding ability, and improves the product quality; the smaller diameter end of the riser body is provided with a conical groove structure, so that a pressure value equal to the outside can be maintained under the condition of keeping a larger thermal modulus; one riser can simultaneously feed four castings, so that the utilization rate of the template can be effectively improved, the utilization rate of equipment is improved, and the production cost is reduced; the mode of the shared riser can effectively reduce the times of riser separation operation and reduce the labor intensity when the riser is removed; the structure is applied to bracket products of a horizontal modeling production line, and the application range is relatively wide; this structural design is simple, and processing preparation is convenient, and it is little to occupy the template space, can promote template effective area utilization, promotes the step rate of staying of product greatly.
