Description

Technical Field

[0001] The utility model relates to the technical field of casting boxes, in particular to a casting box for wear-resistant castings. Background Art

[0002] Casting is a kind of metal heat processing technology that humans mastered relatively early. Casting is a method of pouring liquid metal into a casting cavity that is adapted to the shape of the part, and then cooling and solidifying it to obtain a part or blank. The cast material is mostly a metal that was originally solid but heated to a liquid state (for example: copper, iron, aluminum, tin, lead, etc.), and the material of the mold can be sand, metal or even ceramic. In response to different requirements, the methods used will also be different. With the increase in population now, people need to use more and more tools. In the manufacturing process of tools, some need to be manufactured manually, and some need to be manufactured by molds. When molds are needed for manufacturing, casting is required, and the casting mold needs to be placed in a casting box for cooling and molding.

[0022] In this embodiment, the vibration mechanism includes a groove 8, which is opened at the top center position of the base plate 1. A limiting rod 15 is fixedly installed on the inner wall of the groove 8. A sliding block 14 is slidably installed on the outer side of the limiting rod 15, and the sliding block 14 is fixedly installed on the bottom of the casting box 2.

[0023] In this embodiment, a sliding hole 16 is formed on the sliding block 14 , and the limiting rod 15 is slidably connected to the inner wall of the sliding hole 16 .
