Hook Casting System

Abstract

The invention provides a coupler body casting system, and relates to the field of machine manufacturing. The coupler body casting system comprises a casting mold, a first paste piece, a second paste piece, a pouring system, a first open riser and at least one first blind riser, wherein the casting mold comprises an upper mold, a lower mold, a coupler head, a coupler main body and a coupler tail; the upper mold and the lower mold are buckled to form a coupler body cavity; and one end of the coupler main body is connected with the coupler head, and the other end of the coupler main body is connected with the coupler tail. The first open riser and the at least one first blind riser are located on one surface, which is far away from the lower mold, of the upper mold of the coupler main body and communicate with the coupler body cavity; the pouring system is located on one side of the casting mold and communicates with the coupler body cavity on the upper mold of the coupler main body; the first paste piece is located on one side with the pouring system and communicates with the first open riser and the pouring system respectively; and the second paste piece is located on one side, which is opposite to the pouring system, of the casting mold and communicates with the first open riser and the coupler body cavity of the coupler main body. The coupler body casting system can prevent formation of pores, shrinkage cavities and shrinkage porosity during casting of a coupler body and can reduce the production cost.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a hook body casting system. Background technique [0002] With the rapid development of society, the application of casting is becoming more and more extensive, and people's requirements for castings are getting higher and higher, especially for railway wagon couplers. , most of the hooks use dark risers. Although vent holes are added on the top of the riser, the exhaust effect is not obvious due to the small number and small size of the vent holes. At the same time, the current pouring system The area of ​​the inner runner is too large, it is easy to cause the possibility of air entrainment and back feeding during the pouring process, and the improper setting of the inner runner position and the side riser in the current technology also causes back feeding, which makes the casting The hook body is defective. Contents of the invention [0003] The object of the present...
