Automatic casting system for casting machine

Abstract

The invention provides an automatic casting system for a casting machine. The automatic casting system comprises a cantilever and a piston rod. One end of the cantilever is fixed, the other end of the cantilever is provided with a clamping ring, the middle of the piston rod is arranged in the clamping ring in a sleeved mode, the upper portion of the piston rod is sleeved with piston rod clamping sleeves, the piston rod clamping sleeves are arranged on two clamping plates, the middles of the two clamping plates are connected and fixed through a connection sleeve, the heads of the clamping plates are provided with L-shaped motor bases, two servo motors are arranged on each L-shaped motor base in a lifted mode, lead screws are arranged on motor shafts of the servo motors, the lead screws are meshed with reduction gears respectively, the top of the piston rod is connected with a cylindrical rack, and the rack is meshed with the two reduction gears at the same time. The automatic casting system has the advantages of being reasonable in design and reliable in structure. By means of the automatic casting system, the labor strength of workers can be lowered, and remote control over and intelligent adjusting of lifting actions and adjusting of the piston rod of the system can be achieved; furthermore, the servo motors are controlled through a PLC, high lifting accuracy and high adjusting accuracy are achieved, the wear rate of the piston rod is reduced greatly, the long service life is achieved, and the bottom of a casting ladle is totally free of leakage.

Description

technical field [0001] The invention relates to parts casting equipment, in particular to an automatic pouring system for a pouring machine. Background technique [0002] The bottom pouring pouring machine controls the on and off of the molten iron by the opening and closing action of the stopper rod mechanism. The stopper rod only moves up and down, which can cooperate with the high-efficiency production line to complete the pouring of molten iron. The liquid level of the bottom pouring machine always decreases as the pouring progresses. The diameter of the taphole cannot be adjusted at any time, so it is difficult to achieve constant flow and variable volume control. It can only rely on adjusting the stroke of the plug rod to compensate for the fluctuation of the liquid level and realize flow regulation. The plug rod of the bottom pouring machine has high requirements on refractory materials, and its price is relatively expensive, and the plug rod needs to be replaced re...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide an automatic pouring system for a pouring machine to solve the problem that the connecting rod of the existing plug rod mechanism drives the plug rod to reciprocate, causing uneven wear at the end of the plug rod and easy leakage of molten iron, which affects the pouring appearance and castings Pouring quality and other technical issues

At the same time, it solves the technical problems such as inconvenient adjustment of the existing plug rod, low precision, and labor intensity of workers.
