Pouring flat car positioning device

Abstract

The invention relates to a pouring flat car positioning device, and belongs to the field of sand-lined metal mold casting equipment. The pouring flat car positioning device comprises a pouring flat car body, running wheels, a rail and a plurality of positioning mechanisms of the same structure. The pouring flat car body makes contact with the rail through the running wheels. The positioning mechanisms are connected with the rail. Each positioning mechanism comprises a swing rod, a compression spring, a rim contact surface, a swing rod adjustment screw, a spring adjustment screw, a threaded hole seat I and a threaded hole seat II, wherein the rim contact surface is arranged at the head end of the swing rod; the compression spring is arranged under the head end of the swing rod; one end of the compression spring is connected with the head end of the swing rod, and the other end of the compression spring is connected with the head end of the spring adjustment screw; the threaded hole seat I and the threaded hole seat II are both fixed to the inner side of the rail; the swing rod adjustment screw is matched with the threaded hole seat I; the spring adjustment screw is matched with the threaded hole seat II. The pouring flat car positioning device is reasonable in structure, is capable of effectively positioning a pouring flat car body, guarantees the normal conduction of technical operation, and is safe and reliable.

Description

technical field [0001] The invention relates to a device, in particular to a positioning device for a pouring flat car, which belongs to the field of iron mold sand-covered casting equipment. Background technique [0002] In the sand-covered casting production line of iron molds, several pouring flat cars are connected end to end and placed on the track of the pouring section. A thrust is applied to one end of the pouring flat car to make it travel in a pulsating manner. After advancing to a station, all the pouring flat cars are in a suspended state, and then further processing is performed on the iron molds on the pouring flat car. [0003] In the current production line, because the pouring flat car is not positioned, after the pouring flat car travels on the track and pauses at a station, sometimes there will be a large movement back and forth, which affects the process operation. [0004] The publication date is March 18, 2015, and the Chinese patent with the publicati...

Problems solved by technology

The patent includes a frame equipped with rollers and push handles, a pouring ladle, a rotating shaft, a cylindrical ring, a support rod, screws and a limit block. There is a rotating handle, this patent can improve pouring efficiency and reduce the waste of molten iron, but its function and structure are different from this application, and this application is used in the production line, so it still has defects
