[0027] See attached Figure 1-3 As shown, an embodiment of the utility model is a one-mold-multiple casting mold for a grouting sleeve, comprising a lower mold base 1 and an upper mold base 2, wherein a casting port 203 and an exhaust port 204 are provided on the top of the upper mold base 2, a mold groove 101 is provided on the top of the lower mold base 1, a movable plate 4 is slidably arranged inside the mold groove 101, a grouting sleeve forming core 5 is detachably installed on the top of the movable plate 4, and a slider 601 is slidably arranged inside the guide groove 102.

[0028] The adjusting mechanism is used to adjust the position of the movable plate 4, and the adjusting mechanism includes a U-shaped rod 6 and an inverted U-shaped positioning rod 201. A guide groove 102 is provided on the top of the lower mold base 1, and a through groove 103 is provided at the lower end of the lower mold base 1. The U-shaped rod 6 is arranged in the through groove 103, and one end of the U-shaped rod 6 extends into the inside of the guide groove 102, and the other end of the U-shaped rod 6 is fixedly connected to the bottom of the movable plate 4. Both ends of the inverted U-shaped positioning rod 201 are provided with scales 2021. When the lower mold base 1 and the upper mold base 2 are molded, the inverted U-shaped positioning rod 201 is The lower end of the positioning rod 201 slides through the bottom of the upper die base 2 and can extend into the interior of the guide groove 102. The bottom of the inverted U-shaped positioning rod 201 is fixedly connected with a pressure plate 2022, and the bottom of the pressure plate 2022 can be pressed on the top of the slider 601. The side of the upper die base 2 is equipped with a fastening handle bolt 205 for fixing the inverted U-shaped positioning rod 201 on the upper die base 2. The upper sleeve of the U-shaped rod 6 is provided with a spring 7, and the bottom of the spring 7 is pressed on the bottom of the guide groove 102, and the upper end of the spring 7 is against the bottom of the slider 601.

[0029] In order to ensure that the movable plate 4 does not move downward during casting, an internal threaded sleeve 9 is rotatably installed in the through groove 103, and the upper end of the internal threaded sleeve 9 is threadedly rotatably connected to a stud 8, and the top of the stud 8 is fixedly connected to a top plate 10, and the bottom of the top plate 10 can abut against the bottom of the movable plate 4.

[0030] When the embodiment of the utility model is used, the position of the movable plate 4 is set, the lower mold base 1 and the upper mold base 2 are molded together, and according to the length of the grouting sleeve to be produced as needed, the inverted U-shaped positioning rod 201 is pressed in the direction of the lower mold base 1, so that the pressing plate 2022 continuously squeezes the U-shaped rod 6, thereby causing the movable plate 4 to move downward, and the distance the movable plate 4 has fallen can be understood in real time by observing the scale 2021. When the required height is reached, the inverted U-shaped positioning rod 201 is fixed to the upper mold base 2 by tightening the handle bolt 205, and the internal threaded sleeve is rotated so that the top plate 10 is against the bottom of the movable plate 4 at this time.

When the mold is opened, as the upper mold base 2 continuously moves upward, the pressure plate 2022 releases the squeezing of the U-shaped rod 6, and then the movable plate 4 moves toward the top of the mold groove 101 under the elastic force of the spring 7, thereby realizing the function of automatically pushing the formed grouting sleeve out of the mold groove 101.

[0032] In the embodiment of the utility model, a thread groove 3 is formed on the top of the movable plate 4, and the lower end of the grouting sleeve forming mold core 5 is fixedly installed inside the thread groove 3 by means of threads.

[0033] A limiting cylinder 12 is fixedly connected inside the through groove 103, and a limiting rod 11 is fixedly connected to the bottom of the top plate 10. The limiting rod 11 is slidably sleeved inside the limiting cylinder 12 to ensure that the top plate 10 can move up and down stably. In order to facilitate the rotation of the internal threaded sleeve 9, an operating hole 104 connected to the through groove 103 is opened at the lower end of one side of the lower mold base 1.

[0034] In order to facilitate mold opening, handles 206 are fixedly connected to the two opposite side surfaces of the upper mold base 2.

[0035] The above shows and describes the basic principles of the present invention.
