The utility model discloses a carry out the design of the style of calligraphy of falling T with the flange structure in the chassis fixing base to at the bottom surface installation fastening screw of flange, with fix the flange on the chassis fixing base. The flange is fixed on the chassis fixing seat through the fastening screw under the flange. The flange can be effectively fixed, the pressurizing oil cylinder is effectively sealed at the inner ring of the flange, and when the sealing ring needs to be replaced, the sealing ring in the flange can be very conveniently replaced only by detaching the flange below, so that the lifting of the cylinder body of the pressurizing oil cylinder is avoided, the labor force and the time are greatly saved, and the danger of replacing the sealing ring is greatly reduced.
Furthermore, the bottom of the chassis fixing seat is provided with a concave part for accommodating at least part of the mounting plate so as to stabilize the flange and reduce the mounting space of the flange.
Furthermore, the lower end of the mounting plate protrudes out of the bottom surface of the chassis fixing seat, so that a longer guide distance is provided for the piston rod, and the stroke running stability of the piston rod is improved.
Further, the sealing cylinder and the mounting plate are integrally formed to improve structural stability.

Detailed Description
The invention will be further explained with reference to the drawings and the specific embodiments.
Referring to fig. 3 and 4, the present invention provides a pressurizing cylinder for an internal mixer, which is installed on the top of the vertical table 1 of the internal mixer. Wherein the pressurizing cylinder 20 includes a cylinder body 2. The cylinder 2 is provided with a piston rod 3 which can extend and retract downwards. The piston rod 3 is sleeved with a chassis fixing seat 4. The chassis fixing base 4 is disposed at an end of the cylinder body 2 and connected to the stand 1 to support the pressurizing cylinder 20.
