Specific implementation mode
As shown in Figure 1 to Figure 3, it is a kind of embodiment of pipe collar casted die mould in the utility model, pipe collar casted die mould packet
Include upper die and lower die two parts that one time punching molded mold is carried out to blank 6, include in upper mold connect with punching machine it is upper
Die shank 1, the upper die holder 2 being fixedly connected with upper die shank 1 are connected to the fixed plate 3 that connecting cylinder shape punch-pin 4 is used on upper die holder 2,
Fixed plate 3 is connected to the rear side of the mold first half, and the cylindrical male 4 being plugged in fixed plate 3, cylindrical male 4 with
It is set between upper die holder 2 there are one the space for accommodating shaping blank to form the interval of evacuation pipe collar.The rear side end of cylindrical male 4
Face is equipped with the fixed column 41 plugged with fixed plate 3, and fixed column 41 is threaded post, and accordingly, fixed plate 3 is equipped with and consolidates
The internal thread hole that fixed column 41 coordinates, there is the convex surface coordinated with blank 6 in the outer surface of cylindrical male 4.
The male mold support structure being supported to punch-pin is additionally provided in pipe collar casted die mould, concrete form is upper
The front end of die holder is hinged with the support plate 5 being supported to cylindrical male 4, support plate 5 along vertical arrangement, top have with
The free bearing 51 that support plate 5 biases, the bottom of support plate 5 is the supporting surface being supported with cylindrical male 4, and supporting surface is plane
Structure is accordingly machined with the plane coordinated with supporting surface on the surface of cylindrical male 4.Support plate 5 can be in upper die holder
180 ° are rotated around free bearing on 2, after support plate 5 rotates down in place, having can coordinate with the fixed column of cylindrical male 4
The support level being supported to cylindrical male 4 is formed, and is rotated up, makes to have completed stamping forming blank 6 to move back
Go out the discharge level of cylindrical male 4.
Pipe collar casted die mould further includes the mold lower half coordinated with the mold first half, includes lower die in mold lower half
Handle 12 is connected with lower die holder 11 in the top of lower die shank 12, mounting plate 10 is carried on lower die holder 11, in the left and right of mounting plate 10
On both sides, it is respectively articulated with the swinging cavity die 7 formed when closing up for squeezing cavity needed for workpiece shaping, swinging cavity die 7 is
Offer the plate of semi-circular recesses, the hinged place of swinging cavity die 7 and mounting plate 10 is positioned close to the lower section of swinging cavity die 7.
Between swinging cavity die 7 and mounting plate 10, it is that swinging cavity die 7 provides the bullet flicked from center to both sides under natural conditions to be connected with
The spring 8 of power.
When technical staff uses this mold, the mold first half is connected into dynamic structure, such as punching machine, and will be to press
