[0034] The specific workflow is:

[0035] 1. Sand core material feeding process:

[0036] refer to Figure 1 and Figure 2The sand cores fed into the sample feeding chute 2 from the front feeding device are neatly arranged in the chute and tend to move downward as a whole under the action of gravity. Figure 2 As shown in (a), the piston rod of the lower material distribution cylinder 32 extends to block the first sand core 7 at the bottom, and the piston rod of the upper material distribution cylinder 31 extends to block the second sand core 8; then enter Figure 2 (b) shows the process, at this time, the piston rod of the lower material distribution cylinder 32 is retracted, and the first sand core 7 slides down along the sample feeding chute 2 to the bottom of the chute under the action of gravity; then enters Figure 2 (c) shows the process, at this time, the piston rod of the lower material distribution cylinder 32 extends, the piston rod of the upper material distribution cylinder 31 retracts, and the sand core previously blocked by the piston rod of the upper material distribution cylinder 31 moves downward; finally, enter the process as shown in Figure 2 (d) shows the process, at this time, after the second sand core 8 and the sand core behind it slide downward along the sample feeding chute 2 to the piston rod of the lower material dividing cylinder 32, the piston rod of the upper material dividing cylinder 31 extends out to block between the second sand core 8 and the third sand core 9, and one material dividing is completed; through the above-mentioned actions, the sand cores can slide to the bottom of the sample feeding chute 2 in turn, and the subsequent process will be described below taking the first sand core 7 as an example.

[0037] 2. Sand core positioning process:

[0038] After the first sand core 7 slides to the bottom of the sample feeding chute 2, it fails to reach the specified position accurately. At this time, the piston rod of the feeding cylinder 41 extends, pushing the movable V-block 42 installed at the end of its piston rod to move along the guide groove 44 on the side of the sample feeding chute 2 toward the fixed V-block 43. After reaching the limit position of the guide groove 44 close to the side of the fixed V-block 43, the movable V-block 42 and the fixed V-block 43 form a rectangular space. The first sand core 7 is clamped in this space, but the space is slightly larger than the clamped part of the first sand core 7, and does not limit the subsequent rotation of the sand core.

[0039] 3. Pressing and fixing process:

[0040] Combination Figure 1 , Figure 3 and Figure 4 After the first sand core 7 is initially limited by the movable V-block 42 and the fixed V-block 43 , the piston rod of the pressing cylinder 52 is retracted, the pressing rod 53 falls, and the first sand core 7 is pressed by the pressing head 541 on the top surfaces of the two V-blocks.

[0041] 4.Sand core alignment process:

[0042] Combination Figure 5 and Figure 6 When the first sand core 7 is pressed by the pressing head 541, Figure 6(a); then the piston rod of the lifting cylinder 62 at the bottom of the workbench 1 extends out, and sequentially lifts up the connecting plate 63, the rotary cylinder 64, the roller seat 65 and the roller bearing 67, the roller bearing 67 lifts up the first sand core 7, the first sand core 7 lifts up the pressure head 541, the connecting rod 544 extends outward, and the spring 543 is further compressed. At this time, the state is as follows Figure 6 As shown in (b), after the first sand core 7 is lifted up, the rotary cylinder 64 rotates, and the first sand core 7 does not rotate; when the straight line direction of the two roller bearings 67 is consistent with the bottom opening direction of the first sand core 7, the pressure head 541 presses the first sand core 7 downward under the action of the spring 543, so that the roller bearings 67 are stuck at the bottom opening of the first sand core 7, as shown in FIG. Figure 6 (c) As shown; Next, the first sand core 7 will rotate with the rotary cylinder 64, the rotary cylinder 64 rotates 180° from beginning to end and then stops, the lifting cylinder 62 retracts, and the opening direction of the first sand core 7 is aligned, such as Figure 6 (d) As shown; after the first sand core 7 is aligned, it is taken away by the grabbing device provided in the subsequent procedure to carry out the subsequent process operation, and the alignment mechanism 6 is as shown Figure 6 After the resetting is completed as shown in (e), repeat the above steps to align the next sand core.
