Description

technical field

[0001] The invention relates to the technical field of mold equipment, in particular to a microwave heating resin sand core forming device and method thereof. Background technique

[0002] Thermoforming resin sand is one of the fastest-growing casting processes in the past ten years. The castings produced by thermoforming resin sand have precise dimensions, smooth surface, clear edges and corners, low scrap rate, and can save molding hours and improve production. Efficiency, improving working conditions and production environment; it takes a certain amount of time for thermoforming resin sand to heat-cure. After molding and making cores, the resin sand must harden and build a certain strength before the mold can be released. Molding is difficult. As a core box, due to the thicker sand layer, the usual mold-making time ranges from 3 minutes to 10 minutes after molding, plus the mechanical action time, so the hourly efficiency can only be 5-20 boxes / hour; this ...
