Application of Sand Mold Moulding Machine in Foundry for Automated Casting Moulding of Truck Axle Head Castings

Foundry sand mold molding machine


This is the installation of an automated foundry sand mold molding machine for a company that produces automotive parts during 2015. The equipment mainly produces automated casting molding for truck axle head castings and heavy-duty truck wheel hub castings. The sand box size of the sand mold molding machine is 500mm X 600mm, with an adjustable range of 200mm to 300mm for the upper sand box height and 150mm to 250mm for the lower sand box height. The user installed a simple sand mixing equipment and laid a sand mold pouring track according to the old casting workshop. After being shaped by the foundry sand mold molding machine, the sand mold is transported and pushed into the designated pouring track by an automatic load-bearing trolley. During the day, the foundry workers are responsible for the molding of the sand mold. Automatic placement, with pouring workers pouring sand molds in batches at night; (The picture was taken in August 2015, and the equipment has been installed, debugged, and officially put into production and application.).



Casting Plant Pouring Line


On the pouring track line that carries and transports sand molds, we install a hanging track equipped with molten iron pouring bags for users. As most automotive parts castings are made of ductile iron, pouring needs to be completed in a short time, and the weight of the castings is proportional to the weight of the metal iron that needs to be poured in each sand mold. Therefore, during pouring, workers will use the assistance of the pouring crane to make the pouring process easier and faster; The automation level of this type of rail casting line is not high, and it takes up a lot of space on the site. When pouring with a relatively high proportion of molten metal and sand molds, manual fixation and pressing of the sand molds need to be done in advance, which is relatively cumbersome. Therefore, we only recommend it to some casting enterprises with low budget. Of course, its advantage is that it can provide sufficient cooling time for the poured sand molds and old sand, and the old sand does not come into contact with the ground to avoid impurities and low operating costs of the entire line; (Photo taken to record the production and casting situation during equipment maintenance in September 2016)



Sand Mold Modeling of Heavy Truck Wheel Hub Castings


The automated foundry sand molding machine for truck axle head castings and heavy-duty truck wheel hub castings can achieve sand molding effects by placing coated sand cores when the internal structure of the axle center cannot complete sand lifting.
