LOW-PRESSURE IMPREGNATION APPARATUS

摘要

The present invention relates to a low pressure impregnation device which comprises: a base consisting of multiple support frames in which a post is vertically installed on one side, a support bar which is horizontally extended from the top of the post and supported in a hinged manner in cantilever form, a punch which is suspended in a hinged manner from the middle of the support bar and includes a handle with a pusher on the end thereof, a heating temperature controlled electric furnace having a cylindrical compression space formed by the connection of the pusher so that molten alloy in a mold is impregnated into a preform by applying a load with the pusher of the punch, and a weight rod which is suspended in a hinged manner on the end of the support bar and includes a supporting part on the end thereof in order to load weights corresponding to a setting value. According to the invention, as a low pressure impregnator, the punch is able to freely apply low, upward or downward pressure, which enables continuous measurement, eliminates noises, and performs impregnation regardless of spring tension using gravity. In addition, convenient consistent use is possible due to the simple and easy impregnation.
