Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the side structure schematic view of the utility model.
Specific embodiment
In order to which the technical features, objects and effects to utility model are more clearly understood, Detailed description of the invention sheet is now compareed
The specific embodiment of utility model, identical label indicates identical component in the various figures.To make simplified form, in each figure
Part relevant to the utility model is only schematically shown, they do not represent its practical structures as product.
As shown in Figure 1, 2, the utility model is a kind of piston rod forging and molding mold, which includes and large-tonnage
The bottom of the connected upper mould fixed plate 1 of slider of hydraulic press, upper mould fixed plate 1 is connected by upper die plate 2 with shaping upper 3；At
The corresponding position in 3 lower part of type upper mold be equipped with molding lower die 4, molding lower die 4 bottom be disposed with lower mold fixed plate 5,
Lower mold backing plate 6 and bottom plate 7；The shaping upper 3 is rectangular parallelepiped structure, and the lower part of rectangular parallelepiped structure offers arc-shaped groove 8；
Type chamber 9, the top of type chamber and molding lower die 4 are offered on the top position corresponding with shaping upper 3 of the molding lower die 4
Exterior contour be adapted, the lower part of type chamber is arc-shaped type chamber, is offered in the molding lower die 4 of arc-shaped type chamber central bottom
First cylinder cavity 10 offers the second cylinder cavity 11 in lower mold fixed plate 5, and third circle is offered in lower mold backing plate 6
Column type cavity 12, offers jogger hole on bottom plate 7, the first cylinder cavity 10 successively with the second cylinder cavity 11, third circle
Column type cavity 12 is connected with jogger hole, and the mandril 13 being connected with hydraulic cylinder is movably installed in the jogger hole.
A method of piston rod being forged and pressed using piston rod forging and molding mold, includes the following steps: step 1: by steel ingot
Blank heating is to required temperature；Step 2: the steel ingot blank after heating in step 1 is placed in the inner cavity of molding lower die 4,
It drives shaping upper 3 to enter in the type chamber 9 for forming lower die 4 using great tonnage hydraulic machine to suppress steel ingot blank, suppressed
At rear piston rod, that is, plastic；Step 3: after the completion of compacting, shaping upper 3 is driven to exit under molding using great tonnage hydraulic machine
Mould 4；Step 4: the piston end of hydraulic cylinder pushes mandril 13, and mandril 13 pushes molding piston rod to exit molding lower die 4.It needs
It should be noted that piston rod column part is longer in the utility model, need guaranteeing that piston rod density is big and that intensity is high is same
