Device for separating iron mold with casting piece during casting production of sand coated iron mold of wheel castings and method thereof

Abstract

The invention relates to a device for separating iron mold with casting piece during casting production of sand coated iron mold of wheel castings. The ejecting cylinder is arranged on the upper cover plate of the rack, the ejecting cylinder being connected with the ejector rod plate which is provided with a multiplicity of ejector rods. The number and the distributing position on the ejector plate of the ejector rods are in one-to-one correspondence with the number and position of the core-shooting holes of the iron mold. A casting part-connecting device is fixed on the foundation of the rack. One side of the rack is provided with a vibrating device which is in contact with the casting while at work. The iron mold rollgang is arranged below the ejector rod plate and is fixed on the back side of the ejector rod plate, the iron mold rollgang being synchronized with the ejector rod plate. The iron mold stack is fixed on the bottom of the rack and is positioned below the iron mold rollgang. The iron mold positioning device is fixed in the middle of the working position of the iron mold rollgang, the iron mold positioning device being synchronized with the iron mold rollgang. By adopting the aforementioned device, the invention completely separates the casting piece with iron mold through ejecting pressure and vibrating force, and at the same time cleans up residual sands in the cavity of iron mold, which satisfies the production requirement of mass production.

Description

technical field [0001] The invention relates to a device and method for separating iron molds from castings in the production of iron mold sand-covered casting of wheel castings. Background technique [0002] The wheel castings of automobiles include: brake drums, wheel hubs, wheel side reducer shells, etc. The materials are gray cast iron and ductile iron, and the shape is cylindrical castings. The shape is relatively simple, and it belongs to the mass-produced casting type in automotive castings. one. Castings of this kind of material and appearance are more suitable to be produced by iron sand-covered casting, and their economy, product quality, and internal mechanical properties are all better than ordinary sand casting. [0003] For the mass production of iron mold sand-covered casting of automobile wheel castings, the molding of the inner cavity of the casting can be realized by laying the core. In the production, a core making machine must be specially equipped to pr...

Problems solved by technology

The applicant has done a test with a jack, and the 15-ton jack cannot push the casting away from the iron mold, so it can be seen that the tightening force at this time is very large

If a larger jacking force is used to lift the casting at this time, it is likely to cause deformation of the casting due to excessive force, and in severe cases, the casting may even be broken. This is absolutely not allowed in casting production.

Based on the above principles, the mass production of iron mold sand-covered casting of automobile wheel castings cannot be realized at present.
