[0022] See Figure 1 —— Figure 3 The fixture for plaster mold provided by the utility model comprises a bottom plate 4 with a track 10, and clamping parts arranged at both ends of the bottom plate 4 and cooperating with the track 10 to slide relatively, and a downward protrusion 1 is arranged at the lower part of the clamping part.

[0023] The track 10 is a slide track and is arranged on both sides of the bottom of the base plate 4 .

[0024] The clamping component includes a vertical plate 2 and a tongue 5 at the lower part of the vertical plate 2 . Tenons 20 are provided on both sides of the tongue 5 to cooperate with the slide groove track of the bottom plate 4 .

[0025] A limiting component bolt 14 is provided on the slide track of the bottom plate 4. The bolt 14 blocks the tenon 20 of the tongue 5 to limit the sliding range of the clamping component on the bottom plate 4, thereby preventing the clamping component from sliding out of the slide track.

[0026] The protrusion 1 is connected to the tongue 5 by welding via the connecting portion 18 .

[0027] The tongue 5 is provided with a damping component on the upper part thereof to cooperate with the bottom of the base plate 4 to increase the friction between the clamping component and the base plate 4 during sliding for better positioning; the damping component includes a damping pin 16 in contact with the base plate 4 and a spring 15 provided between the damping pin 16 and the tongue 5.

[0028] The vertical plates at both ends of the base plate 4 are provided with positioning components on their opposite sides, and the positioning components include a clamping plate 6 arranged on one of the vertical plates 2 and a clamping wheel 3 arranged on the other vertical plate 2, and the clamping plate 6 is provided with a rubber pad 7. The clamping wheels 3 are arranged in pairs on the vertical plates 2 through mounting pins 13, washers 21 and cotter pins 24; the positioning components can also be clamping wheels 3 arranged on two vertical plates 2.

[0029] A counterweight block 8 is provided on one of the two vertical plates 2, so that the vertical plate 2 can be opened outward when the bottom plate 4 is in a horizontal state. The counterweight block 8 can be installed on the outside of the clamping plate 2 by bolts 9.

[0030] The bottom of the bottom plate 4 is provided with a rotating shaft 11 by means of a screw 23 , and the lower end of the rotating shaft 11 is provided with a positioning pin 12 which can move up and down and a spring 17 arranged between the rotating shaft 11 and the positioning pin 12 .

[0031] The working principle of this utility model:

[0032] The bearing 19 is mounted on the rotating shaft by means of a retaining ring 22, and connected to the frame 25 through the bearing 19 on the rotating shaft 11. First, the gypsum mold a is placed on the fixture. At this time, the vertical plate 2 of one clamping component is in an outwardly open posture due to the action of the counterweight block 8, which is conducive to placing the gypsum mold a on the bottom plate 4 of the fixture. When locked, Figure 4 , Figure 5 As shown, when the frame 25 carrying the clamp of the utility model runs along the track (not shown) to the locking station, the locking device matched with the utility model moves until its two shifting blocks 27 are just located outside the two clamping parts of the clamp, and the locking cylinder 26 drives the two shifting blocks 27 to contract inwards and drive the two vertical plates 2 to slide inwards along the track 10 of the bottom plate 4, and the gypsum mold a is clamped and positioned by the clamping wheel 3 and the rubber pad 7 on the clamping plate 6. After the grouting centrifugal process is completed, the gypsum mold a enters the unlocking and demolding process. When unlocking, as shown in FIG. Figure 6 As shown, after the frame 25 carrying the fixture of the utility model runs to the unlocking station, the unlocking device matched with the utility model moves to the point where its two shifting blocks 29 are just located on the inner side of the protrusions 1 of the two clamping parts of the fixture, and the unlocking cylinder 28 drives the two shifting blocks 29 to open outward, and the protrusions 1 drive the two vertical plates 2 to slide outward along the tracks 10 of the bottom plate 4 to open, thereby loosening the gypsum mold a.
