Detailed Description
The following detailed description of the present invention is provided in connection with the accompanying drawings and the embodiments, and is not intended to limit the scope of the invention.
As shown in fig. 1 and 2, the ejector rod mechanism for the aluminum alloy scroll forging die comprises a lower die holder 1 and a lower die 2, wherein the lower die holder 1 is provided with an ejector rod cavity 3 which is penetrated through along the vertical direction, a lower ejector rod 4 is arranged in the ejector rod cavity 3, the upper end of the lower ejector rod 4 is provided with a plurality of thin ejector rods 5, the diameter of the lower ejector rod 4 is large, and the thin ejector rods 5 are small in diameter and driven by a hydraulic cylinder to lift the lower ejector rod 4. Lower mould 2 is provided with the ejector pin hole that extends to the die cavity from the below to the top, the lower extreme of thin ejector pin 5 is contradicted the upper end of ejector pin 4 down, the upper end of thin ejector pin 5 pass through the ejector pin hole with 2 sliding connection of lower mould, the top surface in ejector pin chamber 3 is located the bottom surface of lower mould 2 or stretches into the inside of lower mould 2. When the device is used, the lower ejector rod 4 ascends to drive the thin ejector rod 5 to ascend, so that the forged scroll plate is jacked up. The thin ejector rod 5 is non-rigidly connected with the lower ejector rod 4, and when the thin ejector rod 5 needs to be replaced, the thin ejector rod 5 can be taken out from the upper part of the lower die 2. When the lower die 2 needs to be replaced, the lower mandril 4 continuously ascends to jack up the lower die 2.
Further, thin ejector pin 5 is four, the tip of the blade of vortex dish is contradicted to the upper end of thin ejector pin 5, and one of them thin ejector pin 5 is located the middle part of vortex dish, and other three thin ejector pins 5 outwards arrange along the circumferencial direction in proper order along the direction of rotation of vortex dish blade, use the thin ejector pin 5 at middle part promptly for circular, other three thin ejector pins 5 become 120 contained angles and distribute. The jacking area is increased by increasing the number of the thin ejector rods 5, so that the thin ejector rods 5 are protected, and the service life of the thin ejector rods is prolonged. The four thin ejector rods 5 are distributed uniformly, so that the jacking pressure is shared uniformly. More importantly, a gap of 0.1mm is reserved between the thin ejector rod 5 and the ejector rod hole, so that the thin ejector rod 5 can be ensured to slide smoothly, and air in the die cavity can be uniformly discharged to the ejector rod cavity 3 along the gap during forging, thereby avoiding the situation that the forming is not full due to the fact that the deep cavity at the bottom of the die cavity is blocked with air. It can be seen that with the construction of this embodiment, a large space is provided to accommodate the gas exhausted from the mold cavity.
Further, the cross section of the thin ejector rod 5 in the middle is circular, and the cross sections of the other three thin ejector rods 5 are waist-circular, so that the jacking area is increased.
Furthermore, the bottom of the lower die 2 is embedded into the lower die base 1, and the top surface of the ejector rod cavity 3 extends into the lower die 2, so that the length of the thin ejector rod 5 is favorably reduced.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
