Description
The utility model relates to a kind of quick building mortion, the quick building mortion of particularly a kind of reaction injection formula.
Shaping (Rapid Prototyping) is a kind of new and high technology that grew up in recent years fast, it is integrated in one advanced technologies such as CAD (CAD), computer-aided manufacturing (CAM), computer numerical control (CNC) (CNC), elaborate servo driving and new material, according to the product Three Dimensional Design Model of constructing on the computer, it is carried out hierarchy slicing, obtain the two-dimensional silhouette in each cross section.According to these profiles, forming head (laser beam or hot shower nozzle) optionally makes raw material (liquid photosensitive resin, plastics, paper etc.) constitute two-dimentional shaping lamella, and progressively is superimposed as three-dimensional objects.
The three-dimensional processing of complexity is resolved into the combination of simple two-dimensional processing owing to be shaped fast, therefore, it needn't adopt traditional machining tool and mould, only needs the man-hour of traditional diamond-making technique 30～50% and 20～35% cost, and sample or mould just can directly manufacture a product.So fast shaping has become a modern advanced column technology of making, the requisite means of concurrent engineering (CE), not only fast but also economize the essential equipment of ground trial-production high-performance new product.The successful Application of transporting a technology will greatly promote manufacturing design, manufacture level, strengthen the market competitiveness of enterprise significantly.
Existing quick building mortion mainly contains following several: (1) laser curing liquid photosensitive resin device (SLA); (2) laser cutting paper apparatus (LOM); (3) laser sintering powder material apparatus (SLS); (4) hot melt covers plastics silk device (FDM); (5) spray molten plastic powder device (TDP).Wherein, the drip molding of laser cutting paper apparatus is a papery, can not directly obtain plastic product; Laser curing liquid photosensitive resin device utilizes photochemical effect, and special one-component photosensitive resin is solidified, its prices of raw and semifnished materials costliness, and drip molding looks like plastics, but mechanical performance can not show a candle to real industrial plastic (for example ABS); Have only the drip molding that laser sintering powder material apparatus, hot melt cover plastics silk device and injection molten plastic powder device to reach as industrial plastic similar mechanical property such as ABS.Because more and more the part of many industrial products adopts working of plastics, therefore, the user of many quick building mortions has very big interest to these back three kinds of devices.
