The machine is suitable for mass production of large and medium-sized casting single side plate single box modeling, can be built up or down the box.the single machine can realize the sand mold compaction and top box molding functions.Dozens of hydraulic contacts are used for compaction of sand mould, which can improve the compactness of sand mould twice, and the compressive strength can be adjusted by itself according to the compactness of sand at different positions to protectThe uniform compactness of sand mold can effectively meet the clay sand modeling requirements of corresponding sand box size.

The machine is simple to operate, flexible to use, easy to repair and maintenance.

The surface of the casting is smooth and the precision is high.Has been widely used in automobile, agricultural machinery parts,Engine, various valves, power accessories and other industries of the casting shop, and by more and more users accept.

Analysis of advantages of molding machine application:

► Improvement of production efficiency;

► The technical level of modeling workers will be reduced, and the labor intensity of workers will be reduced.

► Reduction of production costs

► Improvement of modeling quality

1. Usage

The machine is generally used for foundry casting workshop, mechanical production lines or semi-mechanical production lines.

2. Characteristics

A. Hydraulic multi-contact compaction is adopted to optimize the design of the machine, without oil leakage; moderate specific pressure, no special requirements for sand, more compaction contacts (48pcs), suitable for complex moulding.

B. High pressure compaction, the multi-contacts compacts sand molding,and vibrate with working table(separated from machine frame, and frame without vibration). Therefore, good vibration effect, high hardness and uniform sand moulding(average hardness 85~90 , B type hardness tester),the sand consumption can be as small as 20~30 mm, the compaction ratio is up to 4.2, and the vertical surface hardness of the mold cavity can still reach above HB80.

C. The machine adopts the spring micro-vibration compaction mechanism, large compaction cylinder diameter, high pressure strength,compacted and even sand moldings, it can guarantee quality of casting.The mold stripping structure adopts way of air oil pressure, the mold stripping adopts connecting rod, the synchronous shaft structure, the pressure oil speed regulation, good mold stripping synchronization, realizes the stable drawing by the two lifting cylinders, the connecting rod, and the synchronous shaft. Simple pneumatic pipeline, easy and flexible operation, convenient operation, The machine adopts the spring fully cushioned pneumatic micro-vibration mechanism, no special foundation requirement.

D. The machine increases the stroke of the compaction cylinder, adopts multiple mechanisms to increase the pressure strength, and at the same time, it can pressurize and vibrate according to actual need, so that the elevation and plane hardness of the sand type (including type of complex sand moulding ) are compact and even. Convenient operation and high productivity.

3.Advantage

1. With hydraulic multiple contact compaction, no oil leakage problems.

2. Moderate pressure, no special requirements for sand, and the number of contacts more than 60, suitable for complex model modeling.

3. During compaction, the frame is free of force. The contacts extend downward, the pressure strength is the internal force of compaction.

4. The effect of shock compaction is good. The hardness of the sand mould is high and even.

5. This machine adopts the spring full buffer pneumatic micro vibration mechanism, so it has no special requirement for the foundation, and the mould lifting adopts the connecting rod.

6. Synchronous shaft structure, speed regulation of pneumatic oil, good mould synchronization with free speed control.
