Mould of Iron-oxide-coated-sand moulding production line has Patent No.: ZL201320259198.6
The series of mould has the following characteristics:
1) Shaped in metal composite model, the mould turns to be smaller in dimension; sand core is made into form by the chilling forming technology, which does not only save the electricity used in thermal forming, but also avoids the input of special equipment. In addition, forging by this technology also can ensure the casting accuracy of form and position as well as the quality of its appearance, improve the qualified rate of casting, and meanwhile control the allowance in mould cutting and processing, so as to achieve the objective of saving resources;
2) The mould is processed in gantry numerical control machining center, therefore the labor intensity is alleviated while the accuracy of mould product is enhanced;
4) Moulding assembling position employs split locating pins and bushes since they can be replaced conveniently, thus, greatly reducing the mould maintenance cost.
