It should be understood that the embodiments described herein are only used to explain this application and are not used to limit this application.

[0020] The present utility model provides a portable demoulding jig as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 . The portable demoulding jig includes a base 1, a lower die base 2 and an upper die base 3 located on the top of the lower die base 2. A housing 4 is fixedly connected to the base 1, a handle 10 is fixedly connected to the top of the housing 4, a cylinder 5 fixedly connected to the base 1 is arranged inside the housing 4, a slide rail 6 is fixedly connected to the base 1, a movable chuck 7 and a die core clamping plate 8 are slidably connected to the slide rail 6, a movable shaft 5.1 of the cylinder 5 is clamped with the movable chuck 7, and a plurality of movable die cores 9 passing through the lower die base 2 and the upper die base 3 are clamped inside the die core clamping plate 8.

[0021] As shown in Figure 1 , Figure 2 , Figure 3 , in the present utility model, an air inlet 11 and an air outlet 12 passing through the top wall of the housing 4 are arranged at the top of the cylinder 5, and a pneumatic control switch 13 is fixedly connected to the front side of the housing 4 and the pneumatic control switch 13 is electrically connected to the cylinder 5.

[0022] As shown in Figure 4 , in the present utility model, the cylinder 5 is fixedly connected to the base 1 through a plurality of fixing columns 14, the base 1 and the housing 4 are fixedly connected through a plurality of first bolts 15, the handle 10 is fixedly connected to the housing 4 through two second bolts 16, the slide rail 6 is fixedly connected to the base 1 through two third bolts 17, the movable chuck 7 and the die core clamping plate 8 are fixedly connected through two fourth bolts 18, and the pneumatic control switch 13 is fixedly connected to the housing 4 through a plurality of fifth bolts 19.
