Problems solved by technology
[0003] In the existing technology, casting demoulding is usually carried out by timing, and it is impossible to judge the shape of the internally cast product. The incompletely formed product is fragile and easily deformed by external interference. The deformed product will not be usable, and The addition time of the release agent is not interfered by the internal molding temperature, and the release agent vaporizes and easily blends into the product and generates air bubbles

The invention relates to the technical field of casting, and provides magnesium-aluminum alloy engine casting auxiliary demolding equipment which comprises a moving set. A male die is fixedly connected to the right side of the moving set, circular truncated cones are fixedly connected to the front side and the back side of the male die and located on the right side of the moving set, and the inner wall of the moving set is sleeved with a guide rail. A fixing set is fixedly connected to the right side of the guide rail, an insertion ring is fixedly connected to the inner wall of the fixing set, a spring rod is fixedly connected to the inner wall of the insertion ring, and an arc-shaped block is fixedly connected to the side, away from the insertion ring, of the spring rod. According to the magnesium-aluminum alloy engine casting auxiliary demolding equipment and the manufacturing method, when casting is completed, cooling forming is conducted, and cooling circulation is conducted on the cooling mold, the air bag is cooled, water vapor in the air bag is condensed, the air bag is shrunk, the connecting block is recycled through the reset spring, and therefore the control block does not hinder movement of the demolding rod any more; and the ejection spring ejects and rotates the demolding rod, and the demolding rod performs ejection demolding.
Description
technical field [0001] The invention relates to the field of casting technology, in particular to auxiliary demoulding equipment for magnesium-aluminum alloy engine casting and a manufacturing method. Background technique [0002] Casting is a method of casting liquid metal into a casting cavity that adapts to the shape of the part. After it is cooled and solidified, the method of obtaining parts and blanks. Casting can quickly obtain products, and its casting shape is stable. With the development of the times, Casting products can be seen everywhere in daily production and life. [0003] In the existing technology, casting demoulding is usually carried out by timing, and it is impossible to judge the shape of the internally cast product. The incompletely formed product is fragile and easily deformed by external interference. The deformed product will not be usable, and The addition time of the release agent is also not interfered by the internal molding temperature, and th...
