Adjustable sand shooting barrel for core shooter

Abstract

The invention discloses an adjustable sand shooting barrel for a core shooter. The adjustable sand shooting barrel comprises a base and a barrel body. An adjusting structure is arranged at the upper end of the base, an air cylinder is arranged at the upper end of the base, a connecting rod is arranged at the upper end of the air cylinder, a clamping ring and the barrel body are fixedly mounted through a mounting hole, and a wear-resisting layer is arranged on the upper surface of the clamping ring, so that the wear resistance of the clamping ring is improved and the service life is prolonged.A control panel is utilized, so that the air cylinder moves up and down, and a retractable connecting rod is stretched and retracted, so that the clamping ring and the barrel body is driven for tilt angle adjustment. The automation degree is high and the application range of the barrel body is enlarged. Molding sand can be blown to directions of an upper sand outlet and a lower sand outlet throughan air opening, and the upper sand outlet and the lower sand outlet are each provided with a solenoid valve and a pressure sensor. When the pressure sensors sense pressure, pressure signals can be converted into electric signals, the solenoid valves can be switched on through the control panel so that the molding sand can be conveniently discharged from the upper sand outlet, and the operation issimple.

Description

technical field [0001] The invention relates to the technical field of sand shooting machine equipment, in particular to an adjustable sand shooting cylinder for a sand shooting machine. Background technique [0002] Coated sand core shooting machine is a machine that uses coated sand as raw material and uses the principle of hot core box to make coated sand molds. The raw material for making coated sand cores is phenolic resin coated sand. Enterprises are optimistic about. [0003] However, when using the sand shooting cylinder to inject molding sand, since the position of the sand shooting cylinder is relatively fixed, the sand can only be shot in the same direction, and the angle of the sand shooting cylinder cannot be adjusted. Larger noise, the use effect is not good. [0004] In view of the above problems, the present invention proposes an adjustable sand shooting cylinder for a sand shooting machine. Contents of the invention [0005] The object of the present in...
