[0024] The storage frame 301 is provided with an extrusion block 305 at both ends, which can extrude the water-containing fine sand 316 in the storage frame 301, so that the water-containing fine sand 316 fills the storage frame 301, realizing the wrapping support of the bottom of the injection molded part. The two extrusion blocks 305 are fixedly connected with a connecting plate 308 at the end away from each other. The connecting plate 308 is provided with a guide rod 309. The guide rod 309 is fixedly connected with the lower surface of the storage frame 301. The lower end of the connecting plate 308 is fixedly connected with a guide block 307. The cross-sectional shape of the guide block 307 is a right triangle. The inside of the equipment base 1 is provided with a rack 306. The surface of the rack 306 is provided with a sliding groove 310. The inside of the equipment base 1 is fixedly connected with a vertical plate 311. The vertical plate 311 is slidingly connected with the inside of the sliding groove 310. The surface of the rack 306 is fixedly connected with a connecting frame 312. The surface of the connecting frame 312 is rotatably connected with a pushing roller 313. The inside of the equipment base 1 is rotatably connected with a rotating shaft 315. The top end of the rotating shaft 315 is fixedly connected with a driven gear 314. The inside of the equipment base 1 is fixedly connected with a motor 304. The output shaft of the motor 304 is fixedly connected with a driving gear 303. The driving gear 303 is engaged with the two driven gears 314. The two driven gears 314 are respectively engaged with the two same side racks 306.

[0025] The left side of the storage frame 301 is fixedly connected with a side connecting block 406. The inside of the side connecting block 406 is provided with a guide vertical rod 407. The top end of the guide vertical rod 407 is fixedly connected with a covering frame 401. The covering frame 401 moves up and down in a straight-up and straight-down manner. It can provide more balanced pressure in the process of pressing the injection molded part, prevent the upper surface of the injection molded part from tilting due to uneven pressure, and prevent the position of the injection molded part from moving in the process of pressing the injection molded part. The inside of the covering frame 401 is provided with a plurality of position limiting columns 403. The injection molded part is clamped between the position limiting columns 403, which can prevent the position of the injection molded part from moving in the process of pressing the injection molded part. The cross-sectional shape of the covering frame 401 is a "cross". A plurality of position limiting columns 403 are evenly inserted into the inside of the covering frame 401 in the shape of a "cross". The covering frame 401 and the side connecting block 406 are provided with a second spring 405. The bottom end of the second spring 405 is fixedly connected with the upper surface of the side connecting block 406. The left end of the covering frame 401 is rotatably connected with a rotating ring. The top end of the second spring 405 is fixedly connected with the rotating ring. The pulling force generated by the second spring 405 pulls the covering frame 401 to the direction close to the storage frame 301, so that the position limiting columns 403 press on the surface of the injection molded part.

[0026] The top end of the position limiting column 403 is fixedly connected with a top block 402, the first spring 404 is fixedly connected between the top block 402 and the cover frame 401, and the position limiting column 403 can be pushed back to the original position by the first spring 404 when the position limiting column 403 is separated from the surface of the injection molding part, so as to facilitate the next use.

The clamping rod 408 is clamped with the inside of the connecting clamping block 409.

[0027] By adopting the above technical scheme, when the injection molding part needs to be measured, the injection molding part is placed on the rubber film 302, and the injection molding part is pressed downward, so that the rubber film 302 deforms with the injection molding part. The injection molding part is inlaid in the rubber film 302 and the water-containing fine sand 316. Because the water-containing fine sand 316 and the rubber film 302 deform with the injection molding part, the injection molding part can be completely supported, and the injection molding part of different sizes and shapes cannot be independently and stably placed. Therefore, the injection molding part does not need to be supported by an additional auxiliary support, and the measurement accuracy of the injection molding part is affected by the auxiliary support.

[0028] When the injection molding part is placed on the equipment base 1, the cover frame 401 can be lifted and rotated, so that the cover frame 401 moves directly above the storage frame 301, and the cover frame 401 is pulled by the pulling force generated by the second spring 405 to apply a pulling force to the direction close to the storage frame 301, so that the position limiting column 403 is pressed on the surface of the injection molding part. Because the cover frame 401 moves up and down in a straight up and down manner, more balanced pressure can be provided during the process of pressing the injection molding part, so as to prevent the upper surface of the injection molding part from being inclined due to uneven pressure.

[0029] When the position limiting column 403 is pressed on the surface of the injection molding part, the position limiting column 403 not pressed on the surface of the injection molding part remains in place, and the position limiting column 403 pressed on the surface of the injection molding part moves upward relative to the cover frame 401, so that the injection molding part is clamped between the position limiting columns 403. In this way, the position of the injection molding part during the process of pressing the injection molding part is prevented from moving, so as to prevent large deviation of the position during the subsequent measurement process and affect the measurement accuracy of the injection molding part.

[0030] When the overhang frame 401 is used to press the injection molding part, the clamping rod 408 is clamped in the groove on the connecting clamping block 409 to fix the overhang frame 401, then the motor 304 drives the driving gear 303 to rotate, then drives the two driven gears 314 to rotate, which further drives the two racks 306 to move horizontally, so that the pushing roller 313 is pressed against the inclined surface on the guide block 307, and the two guide blocks 307 and the two pressing blocks 305 move towards each other, thereby extruding the water-containing fine sand 316 in the storage frame 301, filling the storage frame 301 with water-containing fine sand 316, and achieving wrapping and supporting the bottom of the injection molding part, without the need for manual pressing and leveling operations, thereby improving the accuracy of placing the injection molding part and further increasing the measurement accuracy of the injection molding part.

[0032] By adopting the above technical scheme, after the injection molding part is placed, air is transported into the air pipe 502 by the air injection fan 504, then into the vertical pipe 501, and finally sprayed from the strip-shaped air outlet 503, forming a wind wall to block the entry of external light debris into the equipment base 1, affecting the measurement accuracy of the injection molding part in the subsequent measurement process, when air is transported by the air injection fan 504, static electricity is generated by the electrostatic generator 505, and the surface of the dust absorbing piece 506 produces static electricity, which can adsorb dust and other debris in the air when they are sucked in, preventing dust and other light debris from entering the air pipe 502.
