Embodiment 1

[0014] Such as figure 1 As shown, a casting mold includes an upper mold box 1, a lower mold box 2, molding sand 3, a mold cavity 4 inside the mold sand 3 and a flow channel 5 connecting the mold cavity 4 with the outside world, and the mold cavity 4 is provided with Graphite rods 7 passing through the cavity 4. Both ends of the graphite rod 7 are arranged on the parting surface 6 formed between the upper mold box 1 and the lower mold box 2 , and one end is arranged at the communication place between the runner 5 and the mold cavity 4 . Specifically, the graphite rod 7 is a special-shaped graphite rod with several bosses.

[0015] Since the graphite rod 7 has both rigidity and chilling effect, it can effectively eliminate casting hot spots and avoid the scrapping of castings.

Abstract

A casting die comprises an upper molding box, a lower molding box, molding sand, a cavity in the molding sand, and channel connecting the cavity with the outside, and a graphite rod penetrating through the cavity is arranged in the cavity. The graphite rod is arranged in the cavity, and the graphite rod is rigid and has a chilling effect, so casting hot spots can be effectively eliminated, and cast piece scraping is avoided.

Description

technical field [0001] The invention relates to the field of casting, in particular to a casting mold. Background technique [0002] Casting hot spots are due to the nodes or local areas in the castings that solidify slower than the surrounding metal. After solidification, thermal stress is generated, resulting in deformation and cracks in the castings. It is suggested that the castings will have defects such as looseness, cold shut, and pores. It is a common phenomenon in the casting process. question. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a casting mold to overcome the disadvantage that the casting mold in the prior art is likely to cause hot joints of the casting. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a casting mold, including an upper mold box, a lower mold box, molding sand, a mold cavity inside the mold sand,...
