Abstract
The utility model discloses an improved upper die seat of a forging die. An upper die backing plate 5 is added between an upper die core 3 and a die plate 4 to replace a contact portion of an existing upper die seat with an existing upper die core, namely, the existing whole upper die seat is divided into the upper die backing plate 5 and a novel upper die seat 6. The improved upper die seat removes transitional filleted corners easily generating fatigue cracks of the existing upper die seat, thereby fundamentally avoiding the fatigue cracks of the upper die seat.
Description
Technical field
The utility model relates to a kind of mould, relates in particular to a kind of forging mold upper bolster.
Background technology
In the use of aluminium alloy wheel hub forging mold, the place is subjected to very big pressure and moment of torsion always because of the upper bolster knuckle, so occur fatigue crack herein through regular meeting, as shown in Figure 1, specifically sees Fig. 1, finally causes whole upper bolster to be scrapped.
The utility model content
The purpose of this utility model provides a kind of device that fatigue crack appears in upper bolster that solves.
The technical solution of the utility model is: increase upper die plate between upper mold core and template, as shown in Figure 3, be about to existing upper bolster separated into two parts, upper die plate and novel upper bolster.
Upper die plate is arranged between top template and the upper mold core, and described novel upper bolster is arranged at around upper die plate and the upper mold core.
Described upper die plate can be made standard component, exchanges between the mould of difference wheel type and uses.
The utility model is divided into two parts with upper bolster, has removed the upper bolster knuckle that always is subjected to very big pressure and moment of torsion in this way, has so fundamentally avoided upper bolster the situation of fatigue crack to occur.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1 is existing forging mold general assembly schematic diagram
Fig. 2 is existing forging mold upper bolster stressing conditions analysis
Fig. 3 is the forging mold general assembly schematic diagram that the utility model increases upper die plate
Among the figure: the upper bolster of 1-prior art knuckle, 2-prior art, 3-upper mold core, 4-top template, 5-upper die plate, 6-upper bolster.
The specific embodiment
As shown in Figure 2, existing upper bolster knuckle place 1 is subjected to very big pressure and moment of torsion.Vertical direction is stressed from upper mold core among the figure, the stressed pressure from forging molding of horizontal direction.
As shown in Figure 3, a kind of upper die plate of the utility model is to increase a upper die plate 5 in order to substitute existing upper bolster and upper mold core contact portion between upper mold core 3 and top template 4, is about to existing upper bolster 2 (as Fig. 1) and is divided into upper die plate 5 and novel upper bolster 6 (as Fig. 3).So just removed existing upper bolster knuckle 1.
Upper die plate is arranged between top template and the upper mold core, and described novel upper bolster is arranged at around upper die plate and the upper mold core.
Described upper die plate 5 adopts with the upper bolster identical materials to be made.
Claims (1)
1. improved forging mold upper bolster is characterized in that: be made up of upper die plate and novel upper bolster, upper die plate is arranged between top board and the upper mold core, and described novel upper bolster is arranged at around upper die plate and the upper mold core.
