[0024] Reference Figure 1, a mold processing fixture, including a workbench 100, a clamping seat, a suction plate 300 and a clamping plate, wherein the clamping seat is connected to the workbench 100, and a positioning concave angle 210 is formed on the clamping seat, and the positioning concave angle 210 includes a positioning bottom surface and a positioning side surface connected to each other, the positioning bottom surface extends upward at an angle, and the positioning side surface is perpendicular to the positioning bottom surface; the suction plate 300 is connected to the positioning bottom surface, and the top side of the suction plate 300 has a plurality of adsorption holes. In actual application, an air cavity is formed in the suction plate 300, and the plurality of adsorption holes on the top side of the suction plate 300 are respectively connected to the air cavity, and a negative pressure air pump is connected to the air cavity through a pipeline, and negative pressure can be formed at the plurality of adsorption holes to realize negative pressure adsorption positioning of the workpiece; a clamping block 400 is connected to the clamping seat and protrudes from the positioning side surface, and the clamping blocks 400 are respectively arranged on both sides of the clamping seat.

[0025] From the above, it can be seen that the clamping seat has a positioning recessed angle 210 for installing and positioning the suction plate 300. Since the positioning bottom surface of the positioning recessed angle 210 has a certain inclination angle, the suction plate 300 can be conveniently placed and positioned at a certain inclination angle. At this time, a rectangular workpiece is directly placed on the suction plate 300, and a plurality of adsorption pores are used to quickly position the workpiece. Finally, the clamping blocks 400 on both sides of the clamping seat are clamped on both sides of the workpiece. In this way, the raw workpiece with a shape close to the tooth mold can be directly processed, reducing the subsequent cutting and shaping process, improving work efficiency, and positioning the raw workpiece is faster and more convenient, and it is directly positioned at a certain inclination angle, which improves the subsequent processing efficiency of the water transport holes.

[0026] As an embodiment of the clamping seat, the clamping seat includes a base plate 221, a support plate 222 and a pressure plate 223. The base plate 221 is connected to the workbench 100. Two support plates 222 are connected to the base plate 221 at intervals along the left and right directions. The two support plates 222 are respectively formed with the positioning recessed corners 210. The pressure plate 223 is connected to the top sides of the two support plates 222. The two clamping blocks 400 are respectively connected to the left and right sides of the pressure plate 223. The bottom plate 221 and the two support plates 222 form a stable support structure. The suction plate 300 is placed on the two support plates 222. The positioning recessed corners 210 formed on the two support plates 222 are used to position the left and right parts of the suction plate 300 respectively, so that the suction plate 300 is positioned at a certain tilt angle, and the pressing plate 223 is located above the suction plate 300. The raw material workpiece positioned on the suction plate 300 can be close to one side of the pressing plate 223, and the pressing plate 223 is used to limit one side of it, and the clamping blocks 400 on the left and right sides are used to clamp and position the raw material workpiece.

[0027] In this first embodiment, the overall structure of the clamping seat is relatively simple. When raw material workpieces of different specifications need to be processed, the suction cup needs to be replaced, or the two support plates 222 need to be replaced to change different positioning recessed angles 210, so as to position different raw material workpieces.

[0028] After the suction plate 300 is rotated to the positioning concave angle 210 of the two support plates 222, the suction plate 300 can be further connected to the two support plates 222, or the suction plate 300 can be locked and fixed to the two suction plates 300 by screws. In this embodiment, the suction plate 300 can be fixed when the pressing plate 223 is installed. Specifically, the pressing plate 223 has a pressing section extending above the positioning concave angle 210. The pressing section and the pressing plate 223 can be an integrally formed structure, and the pressing section presses the suction plate 300 in the positioning concave angle 210. When installing the suction plate 300, after the suction plate 300 is placed in the positioning concave angle 210 of the two support plates 222, the pressing section is used to press and position the suction plate 300 on the two support plates 222, so as to further press and position the suction plate 300, and the suction plate 300 can be quickly and firmly installed. In practical applications, a waist-shaped hole extending in the left-right direction may be provided on the pressure plate 223 , and screws may be passed through the waist-shaped hole and then connected to the support plate 222 , so that the pressure plate 223 can be pressed and fixed, and the pressure plate 223 can be adjusted left and right.

[0029] like Figure 2 As shown, as the second embodiment of the clamping seat, the clamping seat includes a seat body 231, a clamp 232 and a connecting plate 233, the seat body 231 is arranged on the workbench 100, the positioning recessed angle 210 is formed on the seat body 231, the clamp 232 is connected to the rear portion of the seat body 231, the clamp 232 clamps the suction plate 300 in the positioning recessed angle 210, the connecting plate 233 is connected to the front portion of the seat body 231, and the two clamping blocks 400 are connected to the left and right sides of the connecting plate 233. In this clamping seat, a positioning recessed angle 210 is formed on an entire seat body 231. When installing the suction plate 300, one side of the suction plate 300 is directly placed into the positioning recessed angle 210 to achieve rapid positioning, and then the clamp 232 is used to press against the suction plate 300 to clamp the suction plate 300 in position. At this time, the raw workpiece is placed on the suction plate 300, and the positioning side surface of the positioning recessed angle 210 and the connecting plate 233 can be used to limit one side of the raw workpiece. Finally, the clamping blocks 400 on the left and right sides of the connecting plate 233 are used to clamp the two ends of the raw workpiece to further clamp and fix the raw workpiece.

[0030] In order to facilitate the use of the clamp 232 to clamp and position the suction plate 300, in the present embodiment, the rear side of the seat body 231 is connected with an adjusting rod 234 by a thread, the clamp 232 is slidably connected to the seat body 231 along the front-to-back direction, and the front end of the adjusting rod 234 is rotatably connected to the seat body 231. In actual applications, a threaded sleeve may be provided on the rear side of the seat body 231, and the adjusting rod 234 is cooperatively connected to the threaded sleeve to enhance the rotation stability of the adjusting rod 234. A slide rail or a slide groove may be provided on the bottom side of the clamp 232, and correspondingly, a slide groove or a slide rail is provided on the top side of the seat body 231. The sliding connection between the clamp 232 and the seat body 231 can be achieved through the cooperation between the slide rail and the slide groove. When installing the suction plate 300, the adjusting rod 234 can be rotated to drive the clamp 232 to move in a direction away from the positioning concave corner 210, and then the suction plate 300 is placed in the positioning concave corner 210 for positioning, and then the adjusting rod 234 is reversed to drive the clamp 232 to approach the positioning concave corner 210, and the suction plate 300 is pressed against the positioning concave corner 210. In this way, the suction plate 300 can be easily disassembled and assembled, and suction plates 300 of different specifications and sizes can be replaced during use, thereby improving flexibility and convenience of use.

[0031] Furthermore, the clamping seat also includes a turntable 235, which is disposed on the workbench 100. The seat body 231 can be rotated and positioned along a rotation axis extending in the horizontal direction on the turntable 235. When it is necessary to change the angle of the water transport hole, the seat body 231 can be rotated to change the inclination angle of the suction cup, and the seat body 231 can be positioned after adjusting to the required angle, so that it can more conveniently adapt to different processing needs and further improve the flexibility and convenience of operation.

[0032] There are many structural forms for the seat body 231 to rotate on the turntable 235. For example, two connecting ears are provided on the turntable 235. The seat body 231 is connected between the two connecting ears through a connecting shaft to realize the rotation of the seat body 231 on the turntable 235. When the seat body 231 needs to be positioned on the turntable 235, it is only necessary to lock the seat body 231 on the turntable 235 with bolts. In this embodiment, two arcuate slide rails 236 are arranged at intervals along the left and right directions on the bottom side of the seat body 231. Two arcuate slide grooves are formed on the turntable 235, which are respectively matched and connected with the arcuate slide rails 236. The turntable 235 is connected with a first bolt 237 by threading. The first bolt 237 passes through one of the arcuate slide grooves and presses against the arcuate slide rail 236. In actual applications, the number of first bolts 237 can be multiple, for example, two, to improve the stability of the seat body 231 when it is fixed on the turntable 235. The seat body 231 is connected to the arc-shaped slide rail 236 and the arc-shaped slide groove through mutual cooperation, so that the rotation axis extending in the horizontal direction on the turntable 235 can be rotated. When the inclination angle of the suction cup needs to be adjusted, the first bolt 237 is loosened to make the first bolt 237 leave the arc-shaped slide rail 236. When the adjustment is completed, the first bolt 237 is tightened again, and the end of the first bolt 237 is pressed against the arc-shaped slide rail 236 to lock the seat body 231 on the turntable 235.

[0033] In order to conveniently observe the rotation state of the seat body 231, in this embodiment, a first scale 238 is provided on the seat body 231. In practical applications, the first scale 238 can extend along the length direction of the arc-shaped slide rail 236. The first scale 238 can be used to intuitively view the rotation adjustment angle of the seat body 231, thereby improving the convenience of operation.

[0034] In order to further improve the stability of the suction cup position adjustment, in this embodiment, the clamping seat further includes a base 239, and the base 239 is connected between the turntable 235 and the workbench 100. The turntable 235 can be rotated and positioned along the rotation axis extending in the up-down direction on the base 239. According to different water transport hole processing needs, the turntable 235 can also be rotated along the rotation axis extending in the up-down direction to further adjust the position and orientation of the suction cup, thereby improving the flexibility and convenience of operation.

[0035] A connecting shaft may be provided on the bottom side of the turntable 235, and the connecting shaft may be connected to the base 239 through a bearing, so that the turntable 235 can be rotatably connected to the base 239. In order to position the turntable 235 on the base 239, an annular limit groove is provided on the base 239, and the center of the limit groove is located on the rotation axis of the turntable 235. A limit block is provided in the limit groove, and an upwardly extending connecting stud is connected to the limit block. The connecting stud passes through the limit groove upward and protrudes from the turntable 235. A nut is threadedly connected at the position where the connecting stud protrudes upward from the turntable 235. When the turntable 235 needs to be rotated and adjusted, the nut is first loosened so that the nut does not contact the turntable 235. After the turntable 235 is adjusted, the nut is re-tightened so that the nut is pressed against the turntable 235, and the turntable 235 is pressed against the base 239 to achieve the positioning of the turntable 235. In practical applications, the limit block, the connecting stud and the nut form a fixing pair. Two fixing pairs may be provided between the turntable 235 and the base 239 to improve the locking effect of the turntable 235 .

[0036] In some embodiments, a second scale 240 is provided on the turntable 235. In practical applications, the second scale 240 is arranged around the outside of the base 239. The angle adjusted by the turntable 235 can be visually viewed through the second scale 240, further improving the convenience of operation.
