Cold-box core shooter

Abstract

The invention discloses a cold-box core shooter comprising a sand shooting mechanism, an electrical part, a base, a gas generator, a hydraulic system and an enclosing screen, wherein the electrical part, the base, the gas generator and the hydraulic system are located in the enclosing screen; an opening is arranged on the front side wall of the enclosing screen; a moving door is arranged at the opening; the sand shooting mechanism is located at the upper part of the base; the base comprises two air cushion moving guide rails, a lifting worktable and a moving worktable; the moving worktable is located above the lifting worktable; and the two air cushion moving guide rails are respectively located at two sides of the lower surface of the moving worktable. Through the way, the electrical control system, the hydraulic system and the gas generator are all placed in the enclosing screen, so that the cold-box core shooter is small in occupied area; a proportional valve is adopted in the hydraulic system to regulate speed, so that the cold-box core shooter is high in speed regulation accuracy; and the two air cushion moving guide rails are arranged below the moving worktable, so that the cold-box core shooter is good in wear resistance and guidance performance, stable and reliable in operation and high in motion accuracy.

Description

technical field [0001] The invention relates to a casting equipment, in particular to a cold box core shooter used in the manufacture of sand cores. Background technique [0002] In foundry production, the requirements for sand cores are very high. Sand cores must have sufficient strength, precise dimensions and smooth surfaces. Conventional cold box core shooting machines generally include sand shooting mechanisms, core box clamping and positioning mechanisms and Hydraulic, electrical, and gas production parts, but the motion accuracy of conventional cold box core shooters is low, the mold clamping accuracy is also low, and the motion is unstable, or the layout of the hydraulic station, electric control box, and gas generator of the equipment is scattered. The wiring distance of gas and electricity pipelines is long, the floor area is large, and the environment is not safe. Contents of the invention [0003] The main technical problem to be solved by the present inventio...
