Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in FIGS. 1 to 3, the pressure cooker of the present embodiment includes: bottom plate 1, frame 2, lower mould support 3, lower mould 4, push down cylinder 5, go up mould mounting panel 6 and last mould 7. Frame 2 is fixed on bottom plate 1, and lower mould support 3 is fixed on bottom plate 1, and is located frame 2 one side, and lower mould 4 is installed on lower mould support 3, and push down cylinder 5 installs at frame 2 top, and push down cylinder 5's cylinder head is connected and is gone up mould mounting panel 6, goes up mould 7 and installs on above mounting panel 6, and sets up with lower mould 4 relatively.

The pressure cooker of this embodiment drives through pushing down cylinder 5 and goes up mould 7 and descend to the mould 7 is gone up in the drive and is suppressed the molten iron in lower mould 4, so as to form the pot base, thereby realized the automated production of cast iron pot, reduced the human cost, avoided the potential safety hazard, improved production efficiency.

The cylinder head of the pressing cylinder 5 and the upper die mounting plate 6 are sealed through the organ cover 8, and the problem that the cylinder shaft of the pressing cylinder 5 is covered by smoke dust or dust in the pressing process to influence the smoothness is effectively avoided.

Lower mould 4 detachably installs on lower mould support 3, goes up mould 7 detachably and installs on last mould mounting panel 6, and detachable mounting is convenient for change lower mould 4 and last mould 7 according to the size or the model of the pot that will make.

Because the lower die 4 and the upper die 7 need to be kept coaxially arranged after the lower die 4 and the upper die 7 are replaced, in order to facilitate the adjustment and fixation of the position of the lower die 4 on the bottom plate 1 by an operator, the bottom plate 1 is also provided with the pressing blocks 11, and during installation, after the position of the lower die 4 on the bottom plate 1 is adjusted to enable the lower die 4 and the upper die 7 to be coaxial, the base edge of the lower die 4 is pressed through the pressing blocks 11 to fix the lower die 4. The pressing block 11 is provided with a through hole, the pressing block 11 penetrates through the through hole through a bolt to be fixed on the bottom plate 1, the pressing block 11 can rotate along the bolt, after the position of the lower die is adjusted, the pressing block 11 is rotated to press the edge of the base of the lower die 4, and then the bolt is screwed down.

The cooker press of the embodiment further comprises a high-pressure blowing bracket 12 arranged on the frame 2, and the high-pressure blowing bracket 12 is used for installing a high-pressure dust blowing gun so as to blow out impurities in the lower die 4 and on the surface of the upper die 7.

The pressure cooker of this embodiment still includes: upset cylinder 9 and dwang 10, upset cylinder 9 installs in frame 2, and dwang 10 rotationally installs on 5 tops of air cylinder down, and the dwang 10 is rotationally connected to the cylinder head of upset cylinder 9, and the axis of dwang 10 is perpendicular to air cylinder 5 and the respective axis of upset cylinder 9 respectively, and air cylinder 5 bottoms rotationally installs at frame 2 tops down, and the axis of rotation is parallel with the axis of dwang 10. When the upper die 7 is required to be trimmed, the upper die 7 is rotated outwards by 90 degrees through the matching of the turnover cylinder 9 and the rotating rod 10, the upper die 7 is convenient to be trimmed by an operator, and the turnover cylinder 9 does not act during normal operation.

The pressure cooker of this embodiment still includes: and the control box 13 is connected with the pressing cylinder 5 and the overturning cylinder 9 and is used for controlling the starting, the closing, the speed control and the like of the two cylinders.

The control box 13 is used for controlling the pushing cylinder 5 to accelerate and push down, the cylinder 5 is pushed down in a deceleration mode when molten iron is 10-20 mm close to the lower die 4, the cylinder 5 is pushed down in an acceleration mode when the molten iron is contacted, specifically, four electromagnetic valves can be used for controlling the pushing cylinder 5 in a parallel mode, a speed regulating valve is independently configured at the outlet of each electromagnetic valve and adjusted to a proper opening degree, the speed of the cylinder is controlled by controlling the combination of different valves, the initial speed is high, the cylinder is decelerated at a position 10-20 mm away from the surface of the molten iron, the speed is slow enough when the cylinder is required to be contacted with the molten iron, the molten iron is guaranteed not. For the corresponding moulds of different sizes of iron pans, the distance from the upper mould 7 to the molten iron is preset in a controller of the control box 13, the initial speed and the speed at the position of 10-20 mm are set, and whether the upper mould 7 reaches the position 10-20 mm away from the molten iron or not and contacts the molten iron can be judged through a sensor or the running time. The sensor is temperature sensor, installs at last mould 7 bottom center, keep the sensor with go up the mould 7 bottom flush can, judge the distance through temperature variation.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
