For solving the problem, the utility model provides a kind of valve guide bushing powder press forming machine, described valve guide bushing powder press forming machine comprises single lead screw ex truding briquetting machine and press-moulding die, described press-moulding die comprises upper punch, be provided with the bottom punch of cavity, the core bar matched with bottom punch and the former matched with upper punch and bottom punch, described former is set in the die sleeve of single lead screw ex truding briquetting machine, the cylinder of described former and single lead screw ex truding briquetting machine is fixed, one end of described upper punch is fixed in the upper punch base of single lead screw ex truding briquetting machine, described core bar is located on described bottom punch, described core bar is also located in described upper punch, and described core bar can move relative to upper punch and bottom punch, the core bar extension bar of described core bar and single lead screw ex truding briquetting machine is fixed, the fixed head of described bottom punch and single lead screw ex truding briquetting machine is fixed, the axial line of described bottom punch, the axial line of described upper punch and the axial line of former are located along the same line, described upper punch center is provided with the through hole matched with described core bar, the length of described core bar is greater than the length of described bottom punch, described core bar, bottom punch, upper punch and die combinations form valve guide bushing cavity.
Further, the end face that described upper punch contacts with described upper punch base is provided with groove.
Further, described core bar comprises connector, the first core bar body and the second core bar body, one end of described connector and described first core bar body is fixed, and the other end and the described second core bar body of described first core bar body are fixed, and the diameter of described first core bar body is less than the diameter of described second core bar body.
Further, described core bar is one-body molded.
The utility model valve guide bushing powder press forming machine is matched with upper punch, bottom punch and core bar by former, and upper punch base drive upper punch is squeezed in the powder in the cavity of core bar, bottom punch and female die set synthesis, once extruded; When the demoulding, cylinder drives former to move downward, and simultaneously core bar extension bar drives core bar to move downward, and makes product exit former, and then upper punch base drives upper punch to return, and is so come off by product, is convenient in demoulding, fast.
Accompanying drawing explanation
Fig. 1 is the structural representation of the better embodiment of the utility model valve guide bushing powder press forming machine.
Fig. 2 is the structural representation of upper punch.
Fig. 3 is the structural representation of core bar.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, the better embodiment of the utility model valve guide bushing powder press forming machine comprises described valve retainer powder press forming machine and comprises single lead screw ex truding briquetting machine and press-moulding die, and described mould comprises upper punch 2, is provided with the bottom punch 3 of cavity, the core bar 4 matched with bottom punch 3, the former 5 that matches with upper punch 2 and bottom punch 3.Described former 5 is set in the die sleeve 6 of single lead screw ex truding briquetting machine, and described former 5 is connected with the cylinder of single lead screw ex truding briquetting machine; One end of described upper punch 2 is fixed in the upper punch base 1 of single lead screw ex truding briquetting machine; Described core bar 4 is located on described bottom punch 3, and described core bar 4 is also located in described upper punch 2, and described core bar 4 can move relative to upper punch 2 and bottom punch 3, and described core bar 4 is fixed with the core bar extension bar of single lead screw ex truding briquetting machine; Described bottom punch 3 is fixed with the fixed head of single lead screw ex truding briquetting machine.The length of described core bar 4 is greater than the length of described bottom punch 3; The axial line of the axial line of described bottom punch 3, the axial line of described upper punch 2 and former 5 is located along the same line.Described core bar 4, bottom punch 3, upper punch 2 and former 5 are combined to form valve guide bushing cavity.
Described upper punch 2 center is provided with the through hole 21 matched with described core bar 4, and the end face that described upper punch 2 contacts with described upper punch base 1 is provided with groove 22, and groove 22 plays the effect of exhaust.
The length of described core bar 4 is greater than the length of described bottom punch 3, guarantees that core bar 4 energy and upper punch 2 coordinate.Described core bar 4 comprises connector 41, first core bar body 42 and the second core bar body 43, described connector 41 is fixed with one end of described first core bar body 42, the other end and the described second core bar body 43 of described first core bar body 42 are fixed, the diameter of described first core bar body 42 is less than the diameter of described second core bar body 43, and the second core bar 43 mates with upper punch 2; Described core bar 4 is one-body molded, facilitates the manufacture of technique.When extruding powder, the first core bar 42 is not in former 5.
