Abstract
The utility model relates to a hub die with uniform ejecting force. The hub die comprises an ejecting rod plate, a pushing rod, a rear rim ejecting ring, a return ejecting rod and an ejecting template, wherein the ejecting template is fixed on an upper fixing plate, the ejecting rod plate is arranged between the upper fixing plate and the ejecting template and can move up and down, one end of the pushing rod and one end of the return ejecting rod are fixedly connected with the ejecting rod plate, the other end of the pushing rod penetrates through the ejecting template and is fixedly connected with the rear rim ejecting ring which is arranged on the lower side of the ejecting template, the rear rim ejecting ring is matched with the structure of a rear rim of a hub, and the other end of the return ejecting rod penetrates through the ejecting template. According to the hub die, the rear rim ejecting ring is driven to push out a product downwards when the ejecting rod plate moves, and the rear rim ejecting ring contacts with the entire rear rim of the product, so that the product is stressed uniformly, the product can be separated from an upper die easily, the phenomenon that the product is damaged by drawing and pulling when the ejecting force is not uniform is avoided, the product quality is guaranteed, the demolding effect is good, the speed is fast, the efficiency is high, and the hub die is simple in structure, easy to machine, low in cost and applicable to standard and normal manufacturing.
Description
Technical field
The utility model relates to aluminium alloy wheel hub Machining Technology field, the uniform hub mold of concrete a kind of ejecting force.
Background technology
Hub mold is the visual plant for casting hub, and die cast die sinking pickup need to use push rod to eject wheel hub, and ejecting wheel hub needs central ejector rod and rear rim push rod to eject simultaneously wheel hub.The rear rim push rod often occuring in the actual use procedure eject different in size causing, cause the product stripping deflection to be stuck on the mould, not only affects consecutive production, and cause die lubricant to come off.Cause the rear rim push rod to eject the reason that causes different in size: 1, push rod is different in size causes; 2, rear rim push rod diameter is thin, easily distortion.
The utility model content
For the deficiencies in the prior art, the utility model aims to provide the uniform hub mold of a kind of stripping result ejecting force good, that speed is fast, efficient is high, but its uniform stressed ejects wheel hub, makes wheel hub be easy to deviate from from patrix.
For achieving the above object, the utility model adopts following technical scheme:
The uniform hub mold of ejecting force, it comprises mandrel plate, push rod, rear rim apical ring, return push rod, top template, described top template is fixed on the upper mounted plate, mandrel plate is located between upper mounted plate and the top template and can be moved up and down, one end of described push rod and return push rod all is fixedly connected on the mandrel plate, the other end of push rod passes top template and is fixedly connected with the rear rim apical ring that is arranged at the top template downside, the structure of described rear rim apical ring and wheel hub rear rim is complementary, and the other end of return push rod passes top template.
Preferably, the uniform hub mold of described ejecting force comprises that further one is fixed in the push rod pressing plate on the mandrel plate upper surface.
Preferably, a hydraulic system drives described push rod pressing plate and drives mandrel plate and move downward.
Preferably, the uniform hub mold of described ejecting force further comprises the mandrel plate guide pillar that is fixed in the top template upside, and mandrel plate and push rod pressing plate are through in the described mandrel plate guide pillar.
Preferably, the upper surface of described mandrel plate guide pillar is fixedly connected with one and prevents the latch segment that mandrel plate comes off.
The uniform hub mold of the ejecting force that the utility model is set forth, compared with prior art, its beneficial effect is: drive the downward ejecting product of rear rim apical ring during the motion of the utility model mandrel plate, because the rear rim apical ring contacts with the product rear rim is whole, but uniform stressed ejecting product, product just is easy to patrix like this, stopped to occur being pulled wound when the push rod ejecting force is inhomogeneous, pull the phenomenon of product, guarantee product quality, stripping result is good, speed is fast, efficient is high, and overall structure is simple, be easy to processing, with low cost, pervasive general, the manufacturing of formatting of suitable standard gauge.
Description of drawings
Accompanying drawing 1 is the structural representation of the uniform hub mold of the utility model ejecting force.
Wherein: 1, wheel hub; 2, mandrel plate; 3, top template; 4, push rod; 5, return push rod; 6, push rod pressing plate; 7, mandrel plate guide pillar; 8, rear rim apical ring; 9, upper mounted plate; 10, guide pin bushing; 11, rear rim; 12, casting equipment; 13, latch segment.
The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the uniform hub mold of ejecting force of the present utility model is described further, so that clearerly understand the utility model technological thought required for protection.
As shown in Figure 1, the uniform hub mold of ejecting force, it comprises mandrel plate 2, push rod 4, rear rim apical ring 8, return push rod 5, top template 3, top template 3 is fixed on the upper mounted plate 9, mandrel plate 2 is located between upper mounted plate 9 and the top template 3 and can be moved up and down, one end of push rod 4 and return push rod 5 all is fixedly connected on the mandrel plate 2, the other end of push rod 4 passes top template 3 and is fixedly connected with the rear rim apical ring 8 that is arranged at the top template downside, rear rim apical ring 8 is complementary with the structure of the rear rim 11 of wheel hub 1, and the other end of return push rod 5 passes top template 3.
Be fixed with a push rod pressing plate 6 on the upper surface of mandrel plate 2, drive push rod pressing plate 6 by a hydraulic system (not shown) and move downward and drive mandrel plate 2 and move downward, and mandrel plate 2 moves upward and relies on return push rod 5 to carry out.Particularly, when hydraulic system moves downward by push rod pressing plate 6 drive mandrel plates 2, push rod 4 drives rear rim apical ring 8 and ejects wheel hub downwards, rear rim apical ring 8 and rear rim 11 whole contacts adopt push rod directly to eject the means of wheel hub compared to prior art, and the ejecting force that wheel hub is subject to is even, wheel hub is easy to patrix, stopped the phenomenon that product occurs being pulled wound, pulling when ejecting force is inhomogeneous, guaranteed product quality, stripping result is good, speed is fast, efficient is high.When resetting, top template 3 is positioned on the upper surface of casting equipment 12, at this moment, the lower end of return push rod 5 withstands on the casting equipment 12, moves upward and returns to initial position thereby promote mandrel plate 2.
Do vertical up-or-down movement for making mandrel plate 2, avoid being offset, in the utility model preferred embodiment, also comprised the mandrel plate guide pillar 7 that is fixed in top template 3 upsides, mandrel plate 2 and push rod pressing plate 6 are sheathed on this mandrel plate guide pillar 7 by guide pin bushing 10, for preventing that mandrel plate 2 from coming off from the upper end of mandrel plate guide pillar 7, be fixedly connected with a latch segment 13 in the upper surface of mandrel plate guide pillar 7.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and distortion should belong within the protection domain of the utility model claim all.
