Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, only some embodiments, not all embodiments, of the present invention are described. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1 to 2, an embodiment of an oblique core pulling mold mechanism is shown, and the oblique core pulling mold mechanism includes a core pulling rod 1, a spring 2, a slider 3, an oblique guide post 4, a lower mold forming block 5 and a shovel machine 6, wherein the spring 2 is sleeved on the core pulling rod 1, one end of the spring 2 is connected with the lower mold forming block 5, the left side of the slider 3 is matched with the shovel machine 6, the right side of the slider 3 is attached to the core pulling rod 1, the shovel machine 6 is fixedly provided with the oblique guide post 4, the slider 3 is provided with a guide hole 7, and the guide hole 7 is matched with the oblique guide post 4.
Further as a preferred embodiment, one end of the core rod 1 close to the sliding block 3 is provided with a second bump 11, and the other end of the spring 2 is connected with the second bump 11, so as to provide a force application point for the spring 2 and prevent the spring 2 from sliding out of the core rod 1.
Further as a preferred embodiment, one side of the slide block 3 close to the core rod 1 is provided with three sliding grooves 9 and two guiding holes 7, the fixed core rod 1 slides on the slide block 3 and is not easy to deviate, and the two guiding holes 7 make it easier for the inclined guiding post 4 to move the slide block 3 backwards.
