Abstract

The invention discloses a vacuum forming equipment-based precision casting method of casting products. The method comprises the following steps by a vacuum forming production line: a, vacuum forming; b, casting cooling; c, taking out of casting; d, sand recovery; repeating the steps a-d until the precision casting of all the casting products is finished. The vacuum forming equipment-based precision casting method of casting products is ingenious in process and high in automation degree; through the vacuum forming production line, the steps such as vacuum forming, casting cooling, taking out of casting and sand recovery are respectively completed and the steps are repeated until the precision casting of all the casting products is finished, so that the connection of links in the production process is smooth and the operation is more convenient; both the vacuum forming and the casting cooling are carried out under vacuum condition, so that the surface regularity of the casting products is high the subsequent complicated secondary machining process can be eliminated and the product value is greatly improved.

Description

technical field [0001] The invention relates to the field of metal casting, in particular to a precision casting method for casting products based on vacuum molding equipment. Background technique [0002] For a long time, sand molds used in casting have been reinforced with a binding material in the sand. With the rapid development of vacuum processing technology, in order to obtain better casting products and hope to reduce the waste of sand grains, many domestic manufacturers often use vacuum molding machines to prepare sand molds. [0003] Vacuum molding is to use a thin thermoplastic film, heat it to the softening point, and then cover it on the model plate with holes drilled and sucked from the back, the plastic film will be tightly and evenly covered on the template working surface, Put a sand box with a special structure on the above template, fill the box with free-flowing, non-adhesive sand, and vibrate slightly to make the loose and broken parts of the sand dense...
