Description
技术领域technical field
本发明涉及铸造技术领域，特别涉及一种消失模铸造可旋转立式成型机。The invention relates to the technical field of casting, in particular to a rotatable vertical molding machine for lost foam casting.
背景技术Background technique
消失模铸造是将用EPS(可发性聚苯乙烯)或者STMMA(可发性甲基丙烯酸甲脂与苯乙烯共聚树脂)共聚料制成的白模填埋在型砂里，抽真空紧实后由浇口杯浇入金属熔液。消失模模样遇金属熔液汽化形成型腔，金属熔液充盈型腔凝固成为铸件。Lost foam casting is to bury the white mold made of EPS (expandable polystyrene) or STMMA (expandable methyl methacrylate and styrene copolymer resin) in the molding sand, and then vacuumize and compact it. The molten metal is poured from the pouring cup. The shape of the lost foam meets the vaporization of the molten metal to form a cavity, and the molten metal fills the cavity and solidifies to form a casting.
消失模铸造所用白模一般由成型机成型。成型机根据合模方向可分为立式成型机和卧式成型机。随着时代的发展，工业大规模生产的需求越来越高，成型机在消失模企业的白区当中的应用越来越广泛。传统的立式成型机是成型时上下模合上，珠粒发泡填充模具型腔，然后开模，员工在上模或下模上取下白模。由于人工取模时需要一段时间，这段时间成型机是处于不工作状态，这对于批量生产来说效率太低。The white mold used in lost foam casting is generally formed by a molding machine. The molding machine can be divided into vertical molding machine and horizontal molding machine according to the mold clamping direction. With the development of the times, the demand for industrial mass production is getting higher and higher, and the application of molding machines in the white area of lost foam enterprises is becoming more and more extensive. In the traditional vertical molding machine, the upper and lower molds are closed during molding, the bead foam fills the mold cavity, and then the mold is opened, and the staff removes the white mold from the upper mold or the lower mold. Since it takes a period of time to take the mold manually, the molding machine is not working during this period, which is too inefficient for mass production.
现有技术中成型机的白模通过人工取模的方式完成脱模过程，取模效率低下，导致成型机非工作时间较长，降低了批量生产效率。In the prior art, the white mold of the molding machine is manually taken out to complete the demoulding process, and the mold taking efficiency is low, resulting in long non-working hours of the molding machine and reducing the mass production efficiency.
