[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] The utility model provides Figure 1-3 The core setting device for a complex composite core of a casting shown in the figure comprises: a mold 1, the mold 1 comprising: a mold core 11, a mold hole 12 and a backing plate 13. The mold hole 12 is opened in the middle of the mold core 11, and the backing plate 13 is installed at the bottom of the mold hole 12. The inner cavity of the mold hole 12 can be used to load the composite structure mud core;

[0035] Furthermore, an upper pressing mechanism 2 is provided on the top of the mold 1. The upper pressing mechanism 2 includes: a mounting plate 21, a first oil cylinder 22 and a lower pressing rod 23. The mounting plate 21 is provided above the mold core 11. The first oil cylinder 22 is fixed to the middle of the mounting plate 21. The lower pressing rod 23 is installed at the bottom of the first oil cylinder 22. The lower pressing rod 23 can be driven by the first oil cylinder 22 to press the mud core in the inner cavity of the mold hole 12, and the lower pressing rod 23 can be quickly separated from the mud core.

[0036] Furthermore, the side of the mold 1 is provided with a side pressure rod 3, and multiple side pressure rods 3 are slidably connected with the side of the mold hole 12. Through the side pressure rods 3, it is convenient to cooperate to form a complex mud core structure. The bottom of the mold 1 is fixedly connected with a bearing seat 4, and the mold core 11 is fixed to the top of the bearing seat 4, so that the position of the mold 1 is stable.

[0037] Furthermore, a pushing mechanism 5 is provided in the middle of the supporting seat 4, and the pushing mechanism 5 includes: a second oil cylinder 51, a frame 52 and a plurality of push rods 53. The second oil cylinder 51 is fixed to the bottom of the inner wall of the supporting seat 4, and the frame 52 is fixed to the top of the second oil cylinder 51. The frame 52 is slidably and interpenetratingly connected with the inner cavity of the supporting seat 4, and a plurality of push rods 53 are fixed at the corners of the frame 52 in a rectangular array. The push rods 53 are slidably and interpenetratingly connected with the corners of the mold 1, and a plurality of push rods 53 are fixedly connected to the corners of the mounting plate 21. The push rods 53 are slidably and interpenetratingly connected with the corners of the supporting seat 4. The insertion of the push rods 53 with the supporting seat 4 and the corners of the mold 1 improves the stability of the sliding position of the frame 52, and facilitates the stable pushing of the mounting plate 21, so that the mounting plate 21 can be easily moved above the mold 1, thereby further improving the efficiency of separating the lower pressure rod 23 from the mud core in the mold hole 12;

[0038] Furthermore, the outer wall of the jacking mechanism 5 is provided with a plurality of connecting mechanisms 6 in a rectangular array, and the connecting mechanism 6 includes: a bending rod 61, a connecting ring 62, a connecting rod 63, a ball 64 and a push-pull rod 65. The bending rod 61 is slidably connected to the outer side of the bearing seat 4 in a vertical direction. The bending rod 61 is fixed to the outer wall of the frame 52, so that the plurality of bending rods 61 can keep up with the frame 52 for synchronous movement. The connecting ring 62 is inserted into the top of the bending rod 61, and the connecting rod 63 is fixed to the outer wall of the connecting ring 62, so that the connecting rod 63 can be movable and rotated at the top of the bending rod 61. The ball 64 is fixed to one end of the connecting rod 63, and the push-pull rod 65 is provided on the ball 64. The ball bearings 64 are embedded in the bottom of the push-pull rod 65 between the adjacent side pressure rods 3, so that the bottom of the connecting rod 63 and the push-pull rod 65 can rotate at various angles. One end of the push-pull rod 65 is fixedly connected to one end of the adjacent side pressure rod 3, so that when the frame 52 moves up, the bending rod 61 moves up, so that the connecting rod 63 is driven in the horizontal direction. Since the push-pull rod 65 needs to always remain in a horizontal state, the ball bearings 64 at the end of the connecting rod 63 can only push the push-pull rod 65 to move outward, so that the side pressure rod 3 slides out of the inner cavity of the mold hole 12, which is convenient for multiple side pressure rods 3 to separate at the same time on the mud core, thereby improving the synchronization of the movement of multiple side pressure rods 3 and reducing resource consumption.

[0039] Furthermore, a fixing ring 7 is fixedly connected to the top of the supporting seat 4, and a plurality of push-pull rods 65 are slidably and interlacedly connected with the outer wall of the fixing ring 7. The fixing ring 7 makes the sliding of the push-pull rods 65 more stable.
