Sand molding machine is mainly suitable for Green Sand Molding Line. It is a semi-automatic molding equipment. It is used in pairs. Sand molds are made by vibrating extrusion. The sand molds are divided into cope and drag.

1. The worktable size of Z143 Sand molding machine is 560*465mm, 30-45moulds/h.
The Z143 Sand molding machine is composed of the body, the ejection mechanism, the shock compaction mechanism, the arm indenter part and the pneumatic piping system.
1.1 The fuselage is a sturdy hollow frame workpiece, the upper part supports the indenter part of the rotating arm, the rotating arm hooks the fuselage during compaction so that the compaction force is borne by the fuselage, the fuselage and the shock mechanism are connected together with bolts, and the rotating arm presses the fuselage. In the head part, the indenter is fixed on the rotatable rocker arm, and the indenter has a screw elevator, which can be adjusted to the distance from the indenter to the sand box according to the height of the sand box
1.2 The arm is controlled by the hand-pull valve to control the reciprocating movement of the cylinder piston to realize the movement of the positive arm and the arm.
1.3 The ejection structure consists of two ejector cylinders, connecting rods, balance shafts, ejector tables, ejector rods, etc. When the ejector cylinders are started, the connecting rods, balance shafts and ejector tables are driven to lift the four ejector pins at the same time. The sandbox is unmolded.
1.4 Shock compaction structure. The spring micro-vibration pneumatic compaction structure is adopted, and the compaction shock increases the vibration. The clamping cylinder locks the vibration cylinder block when the mold is lifted, and the clamping cylinder is released when the mold is dropped.
1.5 Pneumatic pipeline system: The input compressed air, through the air filter, removes water and impurities in the compressed air, and then injects lubricating oil through the lubricator to supply various pneumatic components and mechanisms. The machine action is realized by the hand-pull valve console.
1.6 Air supply and lubrication. The machine works with air source as energy source and oil as lubrication. The intake pressure and oil volume are adjusted by the pressure reducing valve and the oil regulating valve respectively. When the air source passes through the lubricator, the oil is sucked into the pipeline according to the siphon principle, and the mist enters each pipeline system for lubrication.

2. After long-term use, the indenter will swing sluggishly and slowly, affecting work efficiency. It is necessary to carefully diagnose the molding machine, analyze the cause of this abnormal situation, and make timely and correct treatment to ensure that the molding machine returns to normal. Sanzhuji suggested that when the pressing head of the molding machine is sluggish and slow, it should be checked step by step from the following steps to finally solve this problem.
2.1 Check the gap between the front and rear plates of the indenter of the Sand molding machine to see if there is any foreign matter such as iron ballast, which can be removed and tested.
2.2 Open the two air intake pipes on the back of the pressure head, pull the control valve in the original position and swing in respectively, to see if the intake air at the nozzle is large enough. If the air intake volume is small, the pressure head of the molding machine swings slowly. Operate the valve until the air is cleaned.
2.3 There is a cover on the indenter of the Sand molding machine. Open it to observe whether the rack is seriously corroded. If this fault occurs, it will also cause the molding and the indenter to move slowly. It can be cleaned with kerosene or gasoline.
