Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
As shown in fig. 1-4, the utility model provides a large-inclined-plane ejection structure of a die casting die, which comprises a die frame 1, wherein a die core 3 is arranged in the middle of the upper end surface of the die frame 1; the die legs 2 are arranged at two sides of the bottom of the die frame 1; the lower top plate 5 is obliquely and movably arranged at the lower side of the die frame 1, an upper top plate 6 is arranged at the upper side of the lower top plate 5, a plurality of ejector pins 4 are obliquely arranged on the lower top plate 5 and the upper top plate 6, and the ejector pins 4 extend into the die core 3; the oil cylinders 10 are symmetrically arranged at two sides of the die frame 1, and the extending rods of the oil cylinders 10 at two sides extend downwards in an inclined way and are connected with two ends of the upper top plate 6.
Specifically, both ends of the lower top plate 5 and the upper top plate 6 extend out of two sides of the mold frame 1, so that a plurality of ejector pins 4 can be arranged on the lower top plate 5 and the upper top plate 6 and uniformly arranged on the mold core 3, stable ejection of products can be realized, and the two oil cylinders 10 run synchronously, so that the lower top plate 5 and the upper top plate 6 can stably move.
The lower top plate 5 is limited in low position, the limiting block 12 is arranged between the die legs 2, one side of the lower top plate 5 is propped against the limiting block 12 when being positioned in low position, and the other side is propped against one of the die legs 2, so that other limiting structures are not required to be arranged, and the limiting block 12 is of a detachable structure and can be replaced as required. Meanwhile, a space avoiding groove 13 is formed in the bottom of the mold frame 1 corresponding to the upper top plate 6, so that the lower top plate 5 and the upper top plate 6 have enough movable space.
In order to accurately control the positions of the lower top plate 5 and the upper top plate 6, a connecting rod 7 is sleeved on an extending rod of the oil cylinder 10, a displacement rod 8 parallel to the extending rod is connected to the outer side end of the connecting rod 7, a displacement block is arranged on the displacement rod 8, and a travel switch 9 matched with the displacement block is arranged on a shell of the oil cylinder 10 side by side.
Meanwhile, a plurality of guide posts 11 are arranged between the lower top plate 5 and the die frame 1, so that the thimble can be prevented from bending.
It should be noted that all directional indicators (such as up, down, left, right, front, and rear are used in the embodiments of the present utility model) are merely for explaining the relative positional relationship, movement conditions, and the like between the components in a certain specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicators are changed accordingly.
