Description
Technical Field
The utility model relates to a mould, specifically speaking are car rear axle initiative spiral bevel gear forges mould.
Background
The existing rear axle driving spiral bevel gear forging die comprises an upper die and a lower die, wherein a cavity and a mandril hole are formed in the lower die, a mandril is inserted into the mandril hole, the lower die adopts a die in the form of an integral structure, the end part of the cavity of the lower die is large in deformation, the die is serious in abrasion, and the service life is short. The blank is easily extruded into the ejector rod hole in the forming process, so that the boss is formed in the ejector rod hole in a forming mode. When the ejecting force is large, the ejector rod can be ejected into the rod part of the molded product, so that the product is scrapped.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a car rear axle initiative spiral bevel gear forges mould.
In order to solve the technical problem, the utility model discloses take following technical scheme:
the utility model provides a car rear axle initiative spiral bevel gear forges mould, includes mould and lower mould, is equipped with the ejector pin hole in the lower mould, and the ejector pin is equipped with down the mold cavity in the ejector pin hole, is equipped with the die sleeve in the lower mould, still includes the die sleeve, is equipped with the die sleeve die cavity in the die sleeve, and the terminal surface is connected with the lower mould under the die sleeve and the lower port of die sleeve die cavity is just to being connected the last port in die cavity down, and the die sleeve up end is connected with last mould.
And a cushion block is arranged at the lower end surface of the lower mold cavity, and a mandril in the lower mold props against the cushion block.
The lower part of the die sleeve is provided with a lower die positioning spigot, the upper end of the lower die is clamped into the lower die positioning spigot for installation and connection, and the die sleeve cavity is communicated with the lower die positioning spigot.
And the upper part of the die sleeve is provided with an upper die guide spigot, and the upper die is clamped into the upper die guide spigot for installation and connection.
And the corners of the upper die guide spigot are set to be fillets.
The cross-sectional area of the cushion block is larger than that of the ejector rod, so that the cushion block blocks the ejector rod hole of the lower die.
The utility model discloses utilize the independent die sleeve that sets up, can reduce mould manufacturing cost, it is fast to change the die sleeve, reduces product pole portion machining allowance, utilizes the cushion to avoid the ejector pin top to wear the product and leads to scrapping, promotes the yields of product processing.
Drawings
FIG. 1 is a schematic sectional structure of the present invention;
fig. 2 is a schematic view of the cross-sectional structure of the middle mold sleeve of the present invention.
Detailed Description
For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.
As shown in the accompanying drawings 1 and 2, the utility model discloses a car rear axle initiative spiral bevel gear forges mould, including last mould 1 and lower mould 3, be equipped with the ejector pin hole in the lower mould 3, the ejector pin 5 has been inserted in the ejector pin hole, is equipped with down model cavity 6 in the lower mould 3, still includes die sleeve 2, is equipped with die sleeve die cavity 7 in the die sleeve 2, and terminal surface is connected with lower mould 3 under the die sleeve 2 and the lower port of die sleeve die cavity 7 is just being connected the last port of model cavity 6 down, and die sleeve 2 up end is connected with last mould 1. Through setting up the structure of separately independent last mould, die sleeve and lower mould to the die sleeve carries out main product shaping as the center, when the die sleeve is extruded when seriously warping, only need change the die sleeve can, go up the mould and the lower mould need not change, has improved change speed, saves the assemble duration.
In addition, a cushion block 4 is arranged at the lower end face position of the lower mold cavity 6, and a top rod 5 in the lower mold 3 abuts against the cushion block 4. The cross-sectional area of the cushion block 4 is larger than that of the ejector rod, so that the cushion block blocks the ejector rod hole of the lower die. By utilizing the cushion block, the problem that the ejector rod penetrates a product can be effectively solved; the problem that a boss is formed due to the fact that blanks are easily extruded into the ejector rod hole in the forming process can be solved, the ejector rod hole is blocked by the aid of the cushion block, and therefore the blanks are prevented from entering the ejector rod hole easily, and the processing yield is effectively improved.
The lower part of the die sleeve 2 is provided with a lower die positioning spigot 8, the upper end of the lower die 3 is clamped into the lower die positioning spigot 8 for installation and connection, and the die sleeve cavity 7 is communicated with the lower die positioning spigot 8. The upper part of the die sleeve 2 is provided with an upper die guide spigot 9, and the upper die 1 is clamped into the upper die guide spigot 9 for installation and connection. The edge of the upper die guide spigot is set to be a fillet. Through last mould location tang and last mould direction tang, can be more quick, accurate realization die sleeve and go up the assembly connection of mould, lower mould, save the assemble duration, avoid appearing the problem of installation mistake.
The utility model discloses in, through dividing into independent three part, be mould, die sleeve and lower mould respectively, the die sleeve is in the intermediate position and is used for connecting mould and lower mould, opens cushion of lower terminal surface department installation in chamber at the lower mould moreover, shelters from the ejector pin hole of lower mould, can the at utmost prevent that blank from getting into the problem in ejector pin hole among the forming process. Utilize the die sleeve as middle shaping atress part, go up mould and lower mould and can not receive the extrusion, what extrusion warp is the die sleeve, only need change the die sleeve when the die sleeve warp seriously, can effectual reduction mould with low costs, dismantle the convenience moreover, save operating time. Utilize the cushion to solve in the forming process blank and extrude into the ejector pin hole easily, form the problem of boss, avoid the ejector pin directly to push into the problem of pushing through the product in the product simultaneously, improve fashioned yields.
It should be noted that the above is only a preferred embodiment of the present invention, and the present invention is not limited to the above, and although the present invention has been described in detail with reference to the embodiments, it will be apparent to those skilled in the art that the technical solutions described in the foregoing embodiments can be modified or some technical features can be replaced with equivalents, but any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
