Conventional horizontal automatic molding machine

The horizontal parting automatic molding machine of this model adopts a structural design of a separate sandblasting cylinder with side sandblasting. It was developed in 2013 and has been widely produced by casting enterprises for automatic molding. It is also the earliest and most common automatic molding machine in all wet sand casting fields in China, with a sandbox size ranging from 400mm to 750mm, a relatively simple structure and mature technology, Therefore, the price is relatively affordable compared to other models of molding machines.

This molding machine is suitable for tidal sand molding with relatively simple appearance and structure of casting products. It uses gas pressure to inject sand from the side to fill the sand box, and then uses hydraulic cylinders to compact the inside of the sand box, thus completing the automatic molding of the sand mold. In general, we will analyze and make judgments based on the overall casting characteristics and requirements of the casting enterprise. Only when we ensure that the molding machine can be competent and meet the requirements of casting production and casting molding can we recommend it to the user group, and the supporting molds of this equipment also have high technical requirements in the development and production process;

In more than 10 years of technological innovation, we have also upgraded and installed a hydraulic cylinder contact secondary compaction device for casting enterprises with a single type of casting in this model of molding machine. This means that after the airflow fills and compacts the sand box, a small oil cylinder contact is used to perform a second compaction at a specific point in the sand mold, In order to improve the compactness of the sand mold and compensate for the problem of uneven sand injection in the face of difficult mold modeling in this model of molding machine;

The electrical components and hydraulic devices of this model of horizontal molding machine were finally finalized and unified in 2018, and all other models of molding machines in the future will also use the same configuration or upgrade based on this configuration. The hydraulic device adopts Siemens frequency conversion from Germany, combined with the Japanese oil yan hydraulic valve group and pump station, which can ensure stable operation and reliability for a long time without stopping, and is quiet during low noise operation; At the same time, its frequency conversion design is also aimed at energy conservation and electricity saving. When the machine is in standby or has no compaction behavior, the hydraulic device enters the idle state.

Under normal circumstances, the control system is equipped with Omron PLC, sensors, safety gratings, and Omron 10 inch touch screen; One click switch for automatic or manual modeling, automatic detection of faults, automatic safety warning for emergency stop, and automatic adjustment of hydraulic station heating and cooling; We can also replace electrical components from other brands according to the user's location, so that users can obtain accessories and related services from brand manufacturers more quickly in the later use, maintenance, and repair of equipment;

The most commonly used and ideal sandbox size range for this molding machine is 510mm -650mm, and the most suitable sandbox pressure is between 0.52-0.60. After the sandbox is closed, a gap of 70mm-85mm should be left between the internal compaction plate and the highest point of the mold. When the above three conditions are met and sufficient external sand margin is retained, the use of high-quality casting sand molding can also achieve excellent production of most types of castings.
