The utility model also comprises the push rod for the demoulding, and described push rod is arranged on low punch, and a described pulled core structure is connected with push rod.When push rod moves upward, can help forging to deviate from die cavity.
The below of die cavity described in the utility model has step, and described low punch is provided with confined planes, and described step plays position-limiting action to confined planes.Step plays position-limiting action to low punch.
The bottom of low punch described in the utility model is lower than the bottom of front mould and rear mold, and the bottom of described low punch is provided with clamping part.The setting of clamping part, conveniently extracts low punch out by clamping part.
The utility model compared with prior art, have the following advantages and effect: simple in structure, reasonable in design, increase after a pulled core structure and No. two pulled core structures, a pulled core structure and No. two pulled core structures are inserted into respectively in these two concave shaped portion, thereby change flow direction and the unit amount of flow of material, eliminate forging because of the forging defect that structural limitations causes the directed meter flow of material to produce, ensured the quality of forging.

Detailed description of the invention
Below in conjunction with accompanying drawing and by embodiment, the utility model is described in further detail, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment.
Referring to Fig. 1 to Fig. 7, the brass forge hot in the present embodiment is breathed out furan mould and is comprised Kazakhstan furan mould body 1, die cavity 2, die shank 3, upper punch 4, low punch 5 and push rod 6.
Kazakhstan furan mould body 1 in the present embodiment comprises front mould 11 and rear mold 12, front mould 11 and rear mold 12 match, after front mould 11 and rear mold 12 assemblings, form die cavity 2 between the two, front mould 11 and rear mold 12 are symmetrical each other, upper punch 4 is fixed on die shank 3, upper punch 4 is engaged in the top of die cavity 2, die shank 3 is for connecting pressing equipment, low punch 5 is engaged in the bottom of die cavity 2, upper punch 4 and low punch 5 relative motions, thereby by material in the interior moulding of die cavity 2, low punch 5 is provided with flow direction for changing material and a pulled core structure 51 and No. two pulled core structures 52 of unit amount of flow, when moulding, a pulled core structure 51 and No. two pulled core structures 52 are engaged in the bottom of die cavity 2.
