Description

A kind of integrated molding forge die

Technical field

The utility model relates to a kind of forge die more particularly to a kind of integrated molding forge dies.

Background technique

Traditional die-casting process is the increase die casting size in the size of finished product, and mechanical add is carried out after the completion of die casting Work, thus the product size met the requirements, for the part of conventional shape, such as the shapes such as regular cylinder and rectangle Die casting efficiency can be improved using such processing technology in shape, while can also be improved the final size quality of product.

But if product size is irregular, such as both ends shown in FIG. 1 use flange end structure, using such work Processing capacity is excessive when skill just may require that machining, has not only affected production efficiency but also has improved production cost, has caused the big of raw material Amount waste.

Utility model content

Technical problem to be solved by the utility model is to provide a kind of integrated molding forge dies, it is intended to will cast The contour structures of part directly form in a mold, reduce machining allowance, while completing the shape control of interlude in a mold, mention Height forging and stamping quality.

In order to solve the above technical problems, the technical solution of the utility model is: a kind of integrated molding forge die, including it is outer Mould and internal model insert, the inner surface of the external mold are matched with the internal model insert, are contradicted each other；The internal model insert It is provided with insert body, the outer surface of the insert body is set as tapered profile, matches with the external mold inner surface；It is described Insert body be internally provided with pattern hole, the insert body is run through in the pattern hole, in the insert body Portion；Flange hole and central shaft hole are provided in the pattern hole, the central shaft hole is located at the center of the insert body, Through the insert body；Flange hole be located at the side of the central shaft hole, be connected with the central shaft hole, prolong Extend to the outer surface of the insert body.

Further, there are two flange hole settings, the both ends of the central shaft hole are symmetrically distributed in.

Further, the cross section of the central shaft hole is for hexagonal shape, and side junction uses arc transition.

Further, the junction of the flange hole and central shaft hole is provided with fillet, described in the fillet connection Flange hole and central shaft hole.

Further, the external mold is set as cylindrical outer shape, is provided centrally with taper hole, and the inner wall of the taper hole is in Circular conical surface is matched with the outer surface of the insert body.

Further, the height of the external mold is higher than the height of the internal model insert.

Compared with prior art, a kind of integrated molding forge die provided by the utility model, passes through flange hole and center Axis hole is once forged and pressed the irregular product of shape, then carries out internal model switching by internal model insert, can be by the suitable of mold Expanded with range, it is only necessary to the replacement of internal model insert can be produced into different products, improve production efficiency.

Fig. 2 shows the left cross-sectional views of forged product.

Fig. 3 shows the main sectional view of the utility model.

Fig. 4 shows the left cross-sectional view of the utility model.

Wherein: 1. external molds, 2. internal model inserts, 3. insert bodies, 4. pattern holes, 5. flange holes, 6. central shaft holes, 7. fillets, 8. taper hole.

Specific embodiment

As shown, a kind of integrated molding forge die, including external mold 1 and internal model insert 2, the interior table of the external mold 1 Face is matched with the internal model insert 2, is contradicted each other；The internal model insert 2 is provided with insert body 3, the insert body 3 Outer surface be set as tapered profile, matched with 1 inner surface of external mold；The insert body 3 is internally provided with type Die hole 4, the insert body 3 is run through in the pattern hole 4, positioned at the inside of the insert body 3；In the pattern hole 4 It is provided with flange hole 5 and central shaft hole 6, the central shaft hole 6 is located at the center of the insert body 3, through the edge Block 3；Flange hole 5 be located at the side of the central shaft hole 6, be connected with the central shaft hole 6, extend to described Insert body 3 outer surface.

Further, there are two the flange hole 5 settings, the both ends of the central shaft hole 6 are symmetrically distributed in.

Further, the cross section of the central shaft hole 6 is for hexagonal shape, and side junction uses circular arc mistake It crosses.

Further, the junction of the flange hole 5 and central shaft hole 6 is provided with fillet 7, and the fillet 7 connects The flange hole 5 and central shaft hole 6.

Further, the external mold 1 is set as cylindrical outer shape, is provided centrally with taper hole 8, the taper hole 8 it is interior Wall is in circular conical surface, is matched with the outer surface of the insert body 3.

Further, the height of the external mold 1 is higher than the height of the internal model insert 2.

Finally, it should be noted that above embodiments being merely intended for describing the technical solutions of the present application, but not for limiting the present application property skill Art scheme, those skilled in the art should understand that, those are modified or wait to the technical solution of the utility model With replacement, without departing from the objective and range of the technical program, should all cover in the scope of the claims of the utility model.
