The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0020] Please see Figures 1-4 ,in Figure 1 This is a structural schematic diagram of the core-pulling and anti-retraction device for sand core molds according to this utility model. Figure 2 This is a front view of the core-pulling and anti-retraction device for sand core molds of this utility model. Figure 3 This is a side view of the core-pulling and anti-retraction device for sand core molds according to this utility model. Figure 4 This is the utility model Figure 3 A cross-sectional view of the AA line structure.
[0021] This utility model provides a core-pulling anti-retraction device for a sand core mold, including an upper mold 101, a lower mold 102 and an anti-retraction component. The upper mold 101 is detachably connected to the lower mold 102 and is located above the lower mold 102. The side of the upper mold 101 and the side of the lower mold 102 cooperate to form a sand injection port 103. The anti-retraction component is disposed on one side of the upper mold 101.
[0022] The anti-retraction assembly includes a fixing plate 104, a placement plate 105, a core-pulling body 106, an anti-retraction component, and an auxiliary component. The fixing plate 104 is fixedly connected to the upper mold 101 and is located on one side of the upper mold 101. The placement plate 105 is fixedly connected to the fixing plate 104 and is located above the fixing plate 104. The core-pulling body 106 is detachably connected to the upper mold 101 and is located between the upper mold 101 and the lower mold 102. The anti-retraction component is disposed above the fixing plate 104, and the auxiliary component is disposed above the fixing plate 104.
[0023] In this embodiment, the fixing plate 104 fixes the positions of the anti-retraction component and the auxiliary component. By controlling the anti-retraction component, the core-pulling body 106 can be inserted into the upper mold 101 and the lower mold 102, and the sand-shooting machine shoots sand into the sand-shooting port 103, thereby enabling core making. At the same time, the structure of the anti-retraction component can prevent the core-pulling body 106 from retracting, and controlling the auxiliary component can increase the sealing during core making, improve the efficiency of core making, and increase the pass rate of the sand core.
[0024] Furthermore, the anti-retraction component includes a drive motor 107, a screw 108, a first limiting block 109, a moving plate 110, and a moving tube 111. The drive motor 107 is fixedly connected to the fixed plate 104 and is located above the fixed plate 104. The screw 108 is fixedly connected to the output end of the drive motor 107 and is located on the side of the drive motor 107 closer to the upper mold 101. The first limiting block 109 is fixedly connected to the screw 108 and is located at the end of the screw 108 away from the output end of the drive motor 107.

The moving tube 111 is fixedly connected to the moving plate 110 and is located on the side of the moving tube 111 away from the drive motor 107.
[0025] In this embodiment, the drive motor 107 is controlled to drive the screw 108 to rotate. The rotation of the screw 108 will drive the moving tube 111 to move through the moving plate 110, thereby driving the core-pulling body 106 to be inserted between the upper mold 101 and the lower mold 102. At the same time, when the screw 108 is not rotating, it can lock the core-pulling body 106 to prevent the core-pulling body 106 from moving backward. The first limiting block 109 can prevent the moving plate 110 from moving beyond the stroke of the screw 108.
[0026] Furthermore, the anti-retraction component also includes a guide rod 112 and a second limiting block 113. One end of the guide rod 112 is fixedly connected to the placement plate 105 and passes through the moving plate 110. The guide rod 112 is slidably connected to the moving plate 110. The second limiting block 113 is fixedly connected to the guide rod 112 and is located at the end of the guide rod 112 away from the placement plate 105.
[0027] In this embodiment, the guide rod 112 can increase the stability of the moving plate 110 when it moves, and the second limiting block 113 can prevent the moving plate 110 from exceeding the stroke of the screw 108 when it moves.
[0028] Furthermore, the auxiliary components include a sealing ring 114, a connecting rod 115, a connecting plate 116, and a driving unit.

The connecting plate 116 is fixedly connected to the connecting rod 115 and is located at the end of the connecting rod 115 away from the sealing ring 114.
[0029] In this embodiment, the drive unit can move the connecting plate 116, thereby moving the sealing ring 114 through the connecting rod 115, so that the sealing ring 114 is attached to the outer surface of the upper mold 101 and the lower mold 102 to prevent material from flying out during sand shooting.
[0030] Furthermore, the drive unit includes a fixed rod 117, a fixed cylinder 118, and a connecting buckle 119. One end of the fixed rod 117 is fixedly connected to the movable plate 110 and is located on one side of the movable plate 110. The fixed cylinder 118 is fixedly connected to the fixed rod 117 and is located at the end of the fixed rod 117 away from the movable plate 110. The connecting buckle 119 is detachably connected to the output end of the fixed cylinder 118 and wraps around the connecting plate 116. The connecting buckle 119 is also detachably connected to the connecting plate 116.
[0031] In this embodiment, the sand-shooting fixing rod 117 fixes the position of the sand-shooting fixing cylinder 118 relative to the moving plate 110, and the connecting buckle 119 can connect the output end of the fixing cylinder 118 to the connecting plate 116.
