[0026] Please see Figures 1 to 4 A full-size core radial simulation testing device includes a testing device mechanism 1, an adhesive injection mold mechanism 3 is installed inside the testing device mechanism 1, and a clamping mechanism 2 is provided on one side of the adhesive injection mold mechanism 3, the clamping mechanism 2 is used to clamp the adhesive injection mold mechanism 3.

[0027] The glue dispensing mold mechanism 3 includes a glue dispensing cylinder 301, and an adjustable inner cylinder 305 that can be raised and lowered is installed inside the glue dispensing cylinder 301. A support base plate 306 is fixedly installed on the outside of the adjustable inner cylinder 305. A lifting plate 303 is fixedly installed on the surface of the glue dispensing cylinder 301, and an adjusting screw 304 is connected inside the lifting plate 303 through a screw sleeve.

[0028] The top of the glue-filling cylinder 301 is bolted to an upper top plate 302, and the upper top plate 302 has a glue-filling hole inside. A sealing ring 307 is provided at the connection between the glue-filling cylinder 301 and the adjusting inner cylinder 305, and the sealing ring 307 is fixed to the surface of the adjusting inner cylinder 305.

[0029] By adopting the above technical solution, the glue-filling mold mechanism 3 can be adjusted according to the length of the original size rock core. During adjustment, the adjusting screw 304 is rotated, and the screw sleeve on the adjusting screw 304 can drive the lifting plate 303 to slide outside the adjusting screw 304, thereby adjusting the height between the glue-filling cylinder 301 and the adjusting inner cylinder 305. The sealing ring 307 slides inside the glue-filling cylinder 301, and the sealing ring 307 can seal the gap between the glue-filling cylinder 301 and the adjusting inner cylinder 305.

During adjustment, rotating the adjusting screw 304 causes the screw sleeve on the adjusting screw 304 to drive the lifting plate 303 to slide outside the adjusting screw 304, thereby adjusting the height between the glue-filling cylinder 301 and the adjusting inner cylinder 305. The sealing ring 307 slides inside the glue-filling cylinder 301, sealing the gap between the glue-filling cylinder 301 and the adjusting inner cylinder 305.

After rotating the clamping screw 202, it can gradually penetrate deeper into the test device housing 101, so that the clamping plate 201 is close to the glue-pouring cylinder 301. The glue-pouring cylinder 301 is clamped and fixed by both sides of the glue-pouring cylinder 301, and the top fixing cover plate 102 is fixedly installed on the top of the test device housing 101 by bolts. After starting the stepper motor 104, the power output end of the stepper motor 104 drives the rotating rod 105 on the test device housing 101 to rotate inside the base 103, thereby adjusting the angle of the test device housing 101.
