DETAILED DESCRIPTION

[0034] The utility model will now be further described in detail with reference to the accompanying drawings.

[0035] See also Figure 1-6 As shown, in this embodiment, an automatic mold separation machine is provided, comprising: a bottom plate 1, a plurality of columns 2 are fixed at opposite ends of the upper side of the bottom plate 1, a workbench 3 is fixed at the upper ends of the plurality of columns 2, an opening 4 is opened in the middle of the workbench 3, and a telescopic assembly 5 corresponding to the opening 4 is installed in the middle of the bottom plate 1, which can drive a movable mold plate 6 to move vertically above the workbench 3, so that the movable mold plate 6 drives the mold plate assembly 10 to move vertically synchronously, thereby better driving the solidified sand mold to slide and cooperate with the inside of the sand box 7, completing the sand box 7 being stationary to achieve the mold separation. Purpose, at the same time, the telescopic component 5 drives the sand box 7 to separate from the sand mold, and the movement is stable and vertical, which effectively improves the stability of the sand mold and the working efficiency of the device. A movable plate 6 is fixed on the top of the telescopic component 5, and a sand box 7 is installed on the upper side of the movable plate 6. A clamping component 8 corresponding to the sand box 7 is installed on the upper side of the workbench 3, which can clamp and fix the sand box 7, effectively preventing the sand mold being separated from the mold from colliding with the sand box 7 due to the shaking of the sand box 7, thereby causing the sand mold to be damaged. The stability of the sand box 7 during separation is effectively improved, and the quality of the sand mold is guaranteed at the same time;

[0036] Slots 9 are provided at the lower parts of the front and rear sides of the sand box 7, and the inner side of the sand box 7 is elastically slidably fitted with a mold plate assembly 10. The middle parts of the front and rear sides of the mold plate assembly 10 are elastically fitted with clamping blocks 11 corresponding to the slots 9. Push block assemblies 12 are installed on the front and rear sides of the sand box 7, and the push block assemblies 12 correspond to the clamping blocks 11 and the slots 9 respectively, so that the push block assembly 12 pushes the clamping block 11 to cancel the clamping relationship with the slot 9, so that the mold plate assembly 10 can better slide and fit in the sand box 7, preparing for the next step of separating the sand mold from the sand box 7 mold. The mold plate assembly 10 corresponds to the movable plate 6.

[0037] The working principle of this device is as follows: when the sand mold is to be separated from the mold, the telescopic component 5 is first started, and the telescopic component 5 drives the movable mold plate 6 to move upward. After the movement is completed, the crane places the sand box 7 above the movable mold plate 6 after the movement is completed, and the clamping component 8 is started.

[0040] When the sand box 7 is clamped, the bidirectional screw 17 is rotated. At this time, the bidirectional screw 17 and the two movable blocks are threadedly matched to drive the two movable blocks to move relative to each other synchronously, so that the two movable blocks drive the two inverted U-shaped telescopic frames 20 to move relatively close or away synchronously, so that the two inverted U-shaped telescopic frames 20 drive the two sliding rods 19 to slide synchronously and cooperate with the middle of the two ends of the sleeve 18. At this time, the two clamping plates 21 clamp and fix the front and rear sides of the sand box 7 to complete the clamping of the sand box 7.

[0041] When the sand mold is to be separated from the die, the mold plate assembly 10 is firstly cancelled from the clamping relationship with the sand box 7, and then the hydraulic cylinder 14 is started, and the output end of the hydraulic cylinder 14 drives the movable plate 6 to move downward, at which time the movable plate 6 drives the multiple telescopic rods 15 to elastically extend and retract synchronously, and at the same time, the multiple telescopic rods 15 slide and fit in the multiple guide sleeves 16, so that the movable plate 6 drives the mold plate assembly 10 to move downward synchronously, so that the mold plate assembly 10 drives the solidified sand mold to slide and fit on the inner side of the sand box 7 and move downward, at which time the solidified sand mold is completely separated from the outside of the sand box 7, thereby completing the mold and die separation of the sand mold.

[0043] When the sand mold is to be separated from the mold, the two screws 26 are rotated first. At this time, the screw 26 is threadedly matched with the first slider 27 and drives the first slider 27 to press downward, so that the first slider 27 squeezes the second slider 28, so that the second slider 28 drives the pushing block 29 to extend into the slot 9. At this time, the pushing block 29 pushes the clamping block 11 to retract to the middle of the front and rear sides of the second rectangular plate 24.

[0045] When the first rectangular plate 22 is connected to the movable plate 6 , a plurality of screws 30 are passed through the first rectangular plate 22 to connect with the movable plate 6 , thereby completing the connection between the first rectangular plate 22 and the movable plate 6 .

[0046] When the sand box 7 is clamped, the motor 31 is started, and the output end of the motor 31 drives the bidirectional screw 17 to rotate. At this time, the bidirectional screw 17 cooperates with the two movable blocks to drive the two movable blocks to move relative to each other synchronously, so that the two movable blocks drive the two inverted U-shaped telescopic frames 20 to move relatively close or away synchronously, so that the two inverted U-shaped telescopic frames 20 drive the two sliding bars 19 to slide synchronously and cooperate with the middle of the two ends of the sleeve 18.
