An automotive connecting rod forging includes an upper die base, an upper module connected in a dovetail configuration within the upper die base, a lower module located below the upper module, and a lower die base. The lower die base comprises two half-die bases and multiple bolts, with the two half-die bases detachably connected by the bolts. A groove is provided on one end face of each half-die base. The lower module is located between the two half-die bases, with both ends of the lower module situated within the groove. The technical problem this invention aims to solve is to provide an automotive connecting rod forging process that is not only simple in structure but also features a separate die base and lower module, facilitating maintenance and replacement, and ensuring precise guidance.

Description

A kind of automobile connecting rod die forging

technical field

The utility model belongs to the field of mechanical processing and relates to die forging of an automobile connecting rod.

Background technique

The four corners of the existing automobile connecting rod forging die are made into convex and concave shapes, which not only wastes mold material for small molds, but also takes a lot of time and labor during processing, and is not conducive to the repair of the mold. It is integrated. When replacing the lower mold, it needs to be replaced as a whole, and the operation is not very convenient.

Contents of the invention

The technical problem to be solved by the utility model is to provide a die forging of an automobile connecting rod, which not only has a simple structure, but also has a separate mold base and a lower module, which is convenient for maintenance and replacement, and has precise guidance.

The technical scheme of the utility model is: a die forging of an automobile connecting rod, including an upper mold base, an upper module is connected with a dovetail in the upper mold base, a lower module is arranged below the upper module, and a lower mold base is also included. The mold base includes two half mold bases and a plurality of bolts, the two half mold bases are detachably connected by bolts, a groove is provided on one end surface of the half mold base, the lower module is located between the two half mold bases, and Both ends of the lower module are located in the groove.

Further, a positioning hole is provided on one side of the mold base half.

Further, a spacer is provided under the lower module.

Further, a dovetail groove is provided on the end surface of the upper mold base close to the lower mold base, and the upper module is connected with the dovetail of the upper mold base through the dovetail groove, and a T-shaped key and a wedge iron are installed in the dovetail groove.

Further, the height of the mold base half is greater than that of the lower module.

The beneficial effects of the utility model are: the lower mold base can be fixed between two half mold bases by bolts, the height of the half mold base is greater than that of the lower module, so that one end of the half mold base protrudes from the lower module, and the two and a half mold bases After the mold base clamps the lower module, a guide groove composed of grooves will be formed above the lower module, which can play a good guiding role. The lower gasket can be used to adjust the height of the lower module. The mold base adopts dovetail connection, so that the upper module can be replaced in time after damage; the T-shaped key and wedge iron can play a role in positioning.

detailed description

As shown in Figures 1 to 3: a kind of automobile connecting rod die forging, comprises upper mold base 1, is connected with upper module 2 by dovetail in upper mold base 1, is provided with lower module 4 below upper module 2, also includes lower mold The lower mold base includes two half mold bases 3 and a plurality of bolts 5, the two half mold bases 3 are detachably connected by bolts 5, a groove 32 is provided on one end surface of the half mold base 3, and the lower The module 4 is located between the two mold base halves 3 , and the two ends of the lower module 4 are located in the groove 32 .

Further, a positioning hole 31 is provided on one side of the mold base half 3 .

Further, a gasket 7 is provided under the lower module 4 .

Further, a dovetail groove 11 is provided on an end surface of the upper mold base 1 close to the lower mold base, and the upper module 2 is dovetailed connected with the upper mold base 1 through the dovetail groove 11, and a T-shaped key 8 and Wedge 6.

Further, the height of the mold base half 3 is greater than that of the lower module 4 .

The usage method of the utility model: firstly, the lower module 4 is loaded into the lower mold base, a spacer 7 can be placed under the lower module 4, and then the lower mold base is fixed on the working table of the press by using the positioning hole 31 Upper, the upper die base 1 is installed on the press slider; press the switch of the press during forging, the slider moves downward, firstly the upper die base 2 falls into the box surrounded by the inner grooves 32 of the two lower die bases to realize Position and guide, and finally fit and press the lower module 4 to realize die forging; after the die forging is completed, the slider is lifted upwards and returned to its position.
