The utility model relates to the field of processing equipment for resin products, in particular to a vacuum water heating mold, which includes a rubber coating layer, a compound layer, a composite reinforcement layer, a copper tube and a copper tube aluminum heating layer, in which the overlayer is laid on the top of the coating layer, the compound material reinforcement layer is laid above the material layer, and the upper layer of the material reinforced layer is laid. A copper tube is arranged on the copper tube to lay a copper tube aluminum powder heating layer, and a compound layer is laid on the copper tube aluminum powder heating layer again. The true air water heating die adopts the above design, which uses copper tube and filling aluminum powder, which is more uniform heat of the whole mold, thus avoiding parts that have been cured in the heating process, not reacting part of the product, forming uneven thermal stress, causing deformation, color difference and other key indicators. At the same time, the use of the composite layer as the surface layer is also convenient for repeated demoulding, thereby avoiding the problem of the accuracy deterioration of the mold produced for a long time.
【技术实现步骤摘要】
真空灌注用的水加热模具
本技术涉及树脂类产品的加工设备领域,具体是一种真空灌注用的水加热模具。
技术介绍
在生产过程中,通常使用大尺寸平板型的加热模具来使树脂类产品加速固化,而采用传统钢制模具进行真空导流(RIM)工艺的造价昂贵:在多次使用后,钢制模具表面因脱模等操作工序,不断的造成平整度降低,脱模困难、制品表面粗糙等系列问题。修复钢制模具表面,也存在翻新费用高昂的问题。
技术实现思路
本技术的目的在于,提供一种发热均匀并便于多次使用的真空水加热模具。为了达到上述目的,本技术是这样实现的:一种真空灌注用的水加热模具,包括胶衣层、复材层、复材增强层、铜管和铜管铝粉加热层;其中,胶衣层上方铺设复材层,复材层上方铺设复材增强层,复材增强层上铺设铜管,在铜管上铺设铜管铝粉加热层,在铜管铝粉加热层上再次铺设复材层。所述的真空灌注用的水加热模具,铜管按“U”字形回路铺设在复材层的全表面,管壁间距5cm,管壁间距空隙处涂布树脂固化剂混合物以及铝粉,树脂固化剂混合物与铝粉的重量比例为1:2,并且铜管具有一个进水口和一个出水口。本真空水加热模具采用上述设计,其使用铜管并填充铝粉,是整个 ...
