Example 1
A spinning die with an extending movable block ring is used on spinning equipment and comprises a top die pressing plate 1, an ejection block 2, a body die 3, an ejection connecting block 4, a movable block ring 5, an ejection connecting rod 6, an ejection rod pressing block 7 and a machine table connecting flange 8. The top die pressing plate 1 is arranged above the body die 3, the top die pressing plate 1 and the body die 3 are matched for fixing a spinning casting, and after the spinning casting is fixed by the top die pressing plate 1 and the body die 3, the spinning casting can do rotary motion along with the spinning die. The spin casting in this embodiment is a hub. The spin casting includes a mounting face 9, spokes 10 and a rim 12.
This phantom 3 fixed connection is in board flange 8 top, and ejecting connecting rod 6 is established in the central axis department of this phantom 3, can slide from top to bottom along this phantom 3. The bottom of the ejection connecting rod 6 extends into the machine table connecting flange 8, an ejection rod pressing block 7 is fixedly mounted at the bottom of the ejection connecting rod 6, and the top of the ejection connecting rod 6 penetrates through the body model 3 and extends to the inner space of the body model 3.
The ejection connecting rod 6 is fixedly provided with an ejection connecting block 4, and the tops of the ejection connecting block 4 and the ejection connecting rod 6 are mutually clamped and fixed through bolts. The ejecting connecting blocks 4 are uniformly distributed on the radial section of the inner space of the body die 3 by taking the central axis of the body die 3 as the center of a circle.
The ejection block 2 is arranged on the upper edge of the inner space of the body mould 3, and the ejection block 2 is fixedly connected above the ejection connecting block 4 through a bolt. The utility model discloses not only can be through the bolt fastening, can also be fixed through the bolt, any mode that can ejecting block 2 of fixed connection and ejecting connecting block 4 is all in the utility model discloses an within the protection scope. The outer surface of the ejection block 2 is matched with the upper edge of the inner surface of the body die 3; the upper surface of the ejection block 2 is matched with the back surface of a spoke 10 of the spinning casting in a fitting manner, and the upper surface of the ejection block 2 keeps a distance with the mounting surface 9 of the spinning casting; the inner surface of the ejection block 2 is kept at a distance from the spokes 10 and the mounting surface 9 of the spinning casting. Such structural design makes the utility model discloses when the drawing of patterns, effort evenly distributed prevents the emergence of drawing of patterns locking on the spinning foundry goods. The ejection block 2 is provided with an annular inner ring protruding out of the bottom surface, and the ejection connecting block 4 is clamped between the body mould 3 and the inner ring, so that the ejection connecting block 4 and the ejection block 2 are connected more firmly.
After the spinning is finished, the oil cylinder enables the ejection connecting rod 6 to slide upwards, and the ejection block 2 is driven by the ejection connecting block 4 to eject upwards and is far away from the body mould 3. Because the ejection blocks 2 are uniformly distributed at the circumferential edge position of the body die 3, stress is uniformly distributed on the spokes 10, and stress is prevented from being concentrated at the central position of the spinning casting, so that the spinning casting is easier to demould, and the production efficiency is improved. The utility model discloses an ejecting piece 2 can be adjusted according to spoke 10's curvature. When spinning castings of different models need to be matched, only one small part, namely the ejection block 2, needs to be replaced, and the whole die change is not needed, so that the development cost of the die is greatly reduced, and the die change efficiency is improved.
