Vacuum-forming production line capable of recycling sand

Abstract

The invention discloses a vacuum-forming production line capable of recycling sand. The vacuum-forming production line comprises a casting mold frame mechanism, a vacuum forming mechanism, a casting mechanism, a sand-casting separation mechanism, a sand recovering mechanism, an electric block device and a crane, wherein the vacuum forming mechanism is used for filling sand into the casting mold frame mechanism and laminating the two sides of the sand; the casting mechanism is used for filling metal melted liquid into the laminated casting mold frame mechanism; the crane is coordinated with the travelling of the electric block device; an inlet of the sand recovering mechanism is communicated with the sand-casting separation mechanism, and an outlet of the sand recovering mechanism is communicated with the vacuum forming mechanism. According to the vacuum-forming production line disclosed by the invention, the sand recovering mechanism is arranged to automatically collect, cool and return sand and remove impurities after foundry; the whole sand recovery process can be automatically finished by the machine, so that the working procedure of manual processing can be avoided, a mass of manpower and material resources can be reduced, the sand utilization efficiency can be greatly improved, the sand recovery timing sequence can be shortened, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to the field of metal casting, in particular to a vacuum molding production line with recyclable sand grains. 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 quickly, and then co...
