[0008] Preferably, the fixed mold base and the fixed mold core are connected by pins.

[0009] Preferably, the core-pulling needle passes through the needle sleeve pressing block.

[0010] Preferably, the inclination between the core-pulling device and the fixed mold core is between twenty-two degrees and twenty degrees.

[0011] Compared with the existing technology, the beneficial effect of the utility model is that multiple inclined holes can be opened on the fixed mold core at one time through the multi-angle core pulling structure, the inclination angle is controlled by the sliding block, the occupied area is small, and at the same time the consistency of the hole opening inclination is improved, thereby improving work efficiency.

[0017] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] Please refer to the instruction manual Figure 1-4 The utility model provides an embodiment: a space-saving front mold multi-angle special inclined pulling structure, including a fixed mold base 1 and a fixed mold core 3, a core pulling structure 2 is provided between the fixed mold base 1 and the fixed mold core 3, and the core pulling structure 2 includes a support bracket and a multi-angle core pulling structure 4; the fixed mold base 1 and the fixed mold core 3 are an open mold structure, and the multi-angle core pulling structure 4 is used to open the inclined hole;

[0019] The multi-angle core pulling structure 4 includes a push plate 41, which is fixedly connected to the supporting bracket. A pressure plate 42 is fixedly provided at the center of the push plate 41. The lower surface of the pressure plate 42 is slidably connected to a sliding block 43. A core pulling device 44 is provided below the sliding block 43. Driving cylinders 45 are fixedly provided on both sides of the lower surface of the push plate 41. The driving cylinders 45 provide power to provide power for the core pulling device 44. There are multiple sliding blocks 43, and a driving cylinder 45 is provided under each sliding block 43. Multiple inclined holes can be opened at one time, and the inclination direction of the core pulling device 44 can be changed by moving the sliding block 43, thereby changing the inclination angle of the inclined hole.

[0020] The core pulling device 44 includes a guide sleeve 441. A driving sleeve 442 is provided on the side of the guide sleeve 441 close to the sliding block 43. A needle sleeve pressure block 443 is fixedly provided on the end of the guide sleeve 441 away from the driving sleeve 442. A needle sleeve 444 is provided on one side of the needle sleeve pressure block 443. A guide rod is provided in the guide sleeve 441 and the driving sleeve 442. A core pulling needle is provided on the end of the guide rod close to the needle sleeve pressure block 443. The top of the guide sleeve 441 is rotatably connected to the sliding block 43, which can change the angle of the guide sleeve 441. Then the core pulling needle moves downward to punch a hole to open an inclined hole.
