[0002] Isostatic pressing is a process in which the object to be processed is placed in a specific mold, and then the mold with the workpiece is placed in a closed container filled with liquid. The pressure is gradually increased through a booster system, and the pressure is transmitted through the liquid, so that each surface of the object is subjected to equal pressure and is formed under the restriction of the mold. During the compression process, the distance between the actual workpiece molecules is reduced, and the density is increased, which causes changes in the physical and even chemical properties of the pressed object.

[0003] The existing isostatic press lacks a structure to increase stability. If the compression cylinder of the isostatic press is damaged during use, it may rebound and rise, which poses a certain safety hazard. Therefore, the utility model provides a mobile isostatic press to solve the problems raised in the above background technology. Utility Model Content

[0032] The spring 17 is provided to utilize the elastic force of the spring 17 to push the trapezoidal block 14 , and the sliding groove 15 and the sliding block 16 are provided to slide, so that the movement of the trapezoidal block 14 can be limited.

[0033] Embedded oil cylinders 4 are fixedly provided on both sides of the upper end of the fixed frame 3, and a movable frame 5 is fixedly provided on the upper ends of the two embedded oil cylinders 4. A screw 6 is threadedly sleeved in the middle of the upper end of the movable frame 5, and a pressure plate 8 is fixedly provided at the lower end of the screw 6. A No. 1 clamping block 9 is fixedly provided at the lower part of the opposite side of the side plates on both sides of the movable frame 5, and a fixed rod 10 is fixedly provided on both sides of the lower end of the movable frame 5. A movable rod 11 is hingedly provided at the lower ends of the two fixed rods 10, and a No. 2 clamping block 12 is fixedly provided at the lower ends of the two movable rods 11.

[0034] The length of the die-casting can be adjusted by rotating the screw rod 6. By hingedly connecting the fixed rod 10 and the movable rod 11, the movable rod 11 can be conveniently opened to one side when resuming the rise, so that the connected No. 2 clamping block 12 is not in contact with the trapezoidal block 14, and the elastic force of the spring 17 is used to return the trapezoidal block 14 to its original position. By setting the No. 1 clamping block 9 to be clamped with the trapezoidal block 14, the equipment cylinder can be prevented from being damaged and rebounding.

[0035] When the device is in use, the No. 1 card block connected to the side rods on both sides of the outside of the mobile frame 5 can be clamped with the trapezoidal block 14, which can prevent the device from being damaged and rising, and increase the stability of the device. The rear inner walls of the two slide grooves 15 all penetrate to the rear end of the fixed frame 3, and the opposite ends of the two springs 17 are fixedly set with the two sliders 16 respectively.

A turntable 7 is fixedly provided on the upper end of the screw 6, and the turntable 7 is provided to facilitate the rotation of the screw 6.

[0036] Working principle: When in use, die-casting is achieved by the expansion and contraction of the embedded oil cylinder 4, and in this process, the side rods on both sides of the mobile frame 5 move downward, and the two internal fixed rods 10 also move downward accordingly, pushing the middle trapezoidal block 14 outward under the action of the spring 17, so that the No. 1 card block 9 connected to the side rods on both sides of the outside of the mobile frame 5 is engaged with the trapezoidal block 14, which can avoid the equipment cylinder being damaged and rebounding. When resuming the ascent, the internal moving rod 11 is opened to one side so that the No. 2 card block 12 connected to the internal moving rod 11 does not contact the trapezoidal block 14, and then the elastic force of the spring 17 is used to return the trapezoidal block 14 to its original position.
