Description
Technical Field
The utility model belongs to forge wheel hub mould and make the field, relate to a modified forges wheel hub mould ejector components of a whole that can function independently structure.
Background
The most central tool in the production process of forging the aluminum alloy hub is a forging die. The forging die mainly comprises an upper bottom plate, a lower bottom plate, an upper die base, a lower die base, an upper die core, a lower die core, an upper die ejector, a lower die ejector, an inserting plate and the like, wherein the ejector is used for pushing a wheel hub blank stained on the die away from the surface of the die so as to enable a manipulator to take away the blank for the next process production.
Due to the product structure, many wheel-type ejector structures have a large diameter at the front and an elongated round bar at the rear. If the ejector with the structure is integrated, raw materials are wasted, and the manufacturing cost is high. Therefore, the existing ejector is made into a split structure, namely a connecting rod and an ejector which are connected by bolts. However, the working temperature of the die is very high and can reach 500 ℃, the strength of the bolt is greatly reduced at the temperature, and the forging frequency is very high, so that the bolt rapidly loses efficacy and is broken under the working condition, the connecting rod and the ejector are separated, and the ejector falls off, and the normal production is seriously influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a modified forges wheel hub mould ejector components of a whole that can function independently structure, this ejector two parts do not use bolted connection, can not take place the condition that the bolt became invalid.
The technical scheme of the utility model is that: an improved ejector split structure of a forging hub die comprises an ejector, a connecting rod, a limiting ring and a limiting rod, wherein the center of a back cavity of the ejector is a cylindrical groove, the outer sides of the grooves are connected with three fan-shaped groove structures, the lower part of each fan-shaped groove is connected with an embedded 7-shaped groove, and three groups of grooves are uniformly distributed; one end of the connecting rod is provided with three fan blades, and a through hole is arranged above the fan blades; the upper part of the limiting ring is in a circular step shape, two through holes are symmetrically formed in the upper part of the limiting ring, and the lower part of the limiting ring is provided with three uniformly distributed fan-shaped bosses; one end of the limiting rod is provided with a round table, the other end of the limiting rod is provided with a rectangular through groove, a rectangular block is arranged in the limiting rod through a shaft, and the rectangular block can rotate up and down. The flabellum structural installation of connecting rod is in the embedded recess of "7" style of calligraphy of liftout ware, and the spacing ring is installed on the connecting rod, and the fan-shaped boss of spacing ring inserts in the fan-shaped recess of liftout ware, and the gag lever post is installed in the through-hole of connecting rod and spacing ring.
The utility model has the advantages of, connecting rod and liftout ware no longer use bolted connection, do not have the bolt to bear load repeatedly under high temperature and carry out work, the condition of just also can not appear connecting failure.

Detailed Description
As shown in figure 1, the existing ejector 1 and the connecting rod 2 are connected by using bolts, and are easy to fail when the ejector bears load at high temperature and frequency.
As shown in figures 2, 3, 4, 5, 6, 7, 8, 9,
an improved ejector split structure of a forging hub die comprises an ejector 1, a connecting rod 2, a limiting ring 3 and a limiting rod 4, wherein the center of a back cavity of the ejector 1 is a cylindrical groove, the outer sides of the grooves are connected with three fan-shaped groove structures, the lower part of each fan-shaped groove is connected with an embedded 7-shaped groove, and three groups are uniformly arranged; one end of the connecting rod 2 is provided with three fan blades, and a through hole is arranged above the fan blades; the upper part of the limiting ring 3 is in a round step shape, two through holes are symmetrically formed in the upper part of the limiting ring, and the lower part of the limiting ring is provided with three uniformly distributed fan-shaped bosses; one end of the limiting rod 4 is provided with a round table, the other end of the limiting rod is provided with a rectangular through groove, a rectangular block is arranged in the limiting rod through a shaft, and the rectangular block can rotate up and down.
During installation, the connecting rod 2 is placed into the fan-shaped groove in the ejector 1, the fan blades are screwed into the 7-shaped embedded groove in the ejector 2 by rotating the connecting rod 1, then the limiting ring 3 is installed into the connecting rod 2, the fan-shaped boss of the limiting ring 3 is inserted into the fan-shaped groove in the ejector 1, and finally the limiting rod 4 is installed in the through holes of the connecting rod 2 and the limiting ring 3.
During operation, three flabellum and the cooperation of liftout ware 1 of connecting rod 2 bear pulling force and thrust, and spacing ring 3 prevents that connecting rod 2 is rotatory, and spacing rod 4 prevents 3 axial motion of spacing ring. Therefore, the structure can realize bolt-free connection, and avoids the occurrence of bolt failure caused by repeated load bearing of the connecting bolt in the original structure at high temperature.
