JPH11798A - Hydraulic and air spring press - Google Patents

Abstract

PURPOSE: To manufacture a false tooth having excellent precision by embedding a wax false tooth into a flask with plaster, holding it between a pressing and fixing frame, embedding it with the pressure of 50 kg and thereafter injecting rice cake-like resin into a flask with the pressure of 50 kg using a pressure welding injector. CONSTITUTION: When the handle 1 is turned to press, a pressing board 5 is lowered, a lower pedestal 6 is pressed and interlocked so as to lower, an oil chamber is pressed, the air within an air chamber is compressed and a figure is displayed on a pressure meter 12.

Description

DETAILED DESCRIPTION OF THE INVENTION

The wax dentures are buried in the flask with gypsum, and the fixing frame is placed on the lower part of the press. The handle is turned and pressurized by 50 kg. Remove the press from the press, set the press-fitting injector, insert the rice cake resin into the syringe, put it on the piston of the press lower platen base and turn the handle. When a pressurizing press is performed, the lower platen piston goes down and the air in the air chamber is compressed, and the oil pressure in the oil chamber appears on the pressure meter from the pipe, and the necessary pressurization can be performed. It is possible to compress the rice cake-like resin because of the spring pressure.
This is a hydraulic and pneumatic puling press.

Claims (1)

[Claims] This hydraulic and pneumatic spring press adjusts the amount of oil and air, puts the handle, turns the handle and presses the press, and the oil and air are compressed by the lower platen piston in the cylinder to act as a spring. The required pressurization can be confirmed by the (12) meter.
