Vacuum gel casting device

Abstract

The invention relates to a vacuum gel casting device. The vacuum gel casting device comprises a vacuum stirring bucket, a vacuum pump and a casting tank. A stirring motor is arranged on the upper portion of the vacuum stirring bucket. The casting tank comprises a tank body. A lifting platform is arranged in the tank body. An end cover is arranged at the top of the tank body. Lifting air cylindersare arranged on the upper portion of the end cover and are connected with the lifting platform through guide columns arranged in the tank body. The vacuum stirring bucket and the casting tank are connected with the vacuum pump through vacuumizing pipes. The vacuum stirring bucket is connected with the end cover through a flow guide pipe, and a discharging control valve is arranged at the joint ofthe vacuum stirring bucket and the flow guide pipe. The height of the bottom of the vacuum stirring bucket is larger than the height of the end cover. The vacuum gel casting device is simple in structure, small in occupied space, convenient to operate, high in grouting efficiency and high in casting quality, a manufactured blank is full in mold filling, uniform and free of bubbles, and the requirement for close-size prefabricated members in the precision machine production process can be met.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a vacuum gel injection molding device. Background technique [0002] Gel injection molding is a method of adding organic monomers, cross-linking agents, initiators, and catalysts into ceramic slurry, injecting the slurry into non-porous membranes, and using temperature to induce polymerization of organic monomers to solidify and form The molding process of the green body. The products processed by this molding process have high dimensional accuracy and high green body strength, and can be machined. [0003] The green body is prepared by the gel injection molding method, which can realize the near-size molding of the large-sized and complex-shaped structural body, and at the same time, the green body can be processed twice, which can reduce the amount of processing to the greatest extent. Therefore, gel injection molding is often used in the preparation of products ...

Problems solved by technology

[0004] Chinese utility model patent specification CN204172180U discloses a vacuum grouting system. The vacuum grouting system has low energy consumption, but the device needs to be provided with a slurry tank and a slurry storage room, and the vertical height difference between the slurry tank and the slurry storage room is as high as 5.7 to 6.1 meters, it takes up a lot of space, has high requirements on the factory building, and is inconvenient to operate

[0005] Chinese utility model patent specification CN204687037U discloses a vacuum grouting machine for ceramics. The vacuum grouting machine needs to be equipped with a slurry pump and an air pump. removal, at the same time, the uniformity of the slurry cannot be guaranteed, which is not conducive to obtaining a high-precision green body
