Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
The embodiments of the present invention is related to a kind of pressing mold equipped with a step hole flanging structure, as shown in Fig. 1-3,
Including upper molded plate 1, lower template 2 and lower moulded board 3, fixed plate 4 is installed in the middle part of 1 lower end surface of upper molded plate, it is described
4 left side vertical of fixed plate left part slotting tool 5 is installed, it is vertically-mounted in 4 right end of fixed plate to have a right part slotting tool 6, it is described
Left part slotting tool 5 lower end on the right side of and the lower end of right part slotting tool 6 on the left of be arranged with inclined surface, on the lower moulded board 3
Vertically-mounted in the middle part of end face to have lower die station 7, the left and right side of the lower die station 7 is separately installed with first moved left and right and drives
Motion block 8 and the second drive block 9, first drive block 8 and the second drive block 9 respectively with left part slotting tool 5 and right part slotting tool 6 one
One is corresponding, is horizontally installed with the flange formed punch 12 across lower die station 7, the fixation on the left of 9 upper end of the second drive block
Positioning pressuring plate 13 corresponding with lower die station 7 is installed in the middle part of 4 lower end surface of plate.
The first spring 17 in compressive state is installed between first drive block 8 and lower die station 7, described second
Second spring 18 in compressive state is installed between drive block 9 and lower die station 7.
Discharging spring mounting hole 14 is provided in the middle part of 13 upper surface of positioning pressuring plate, in 14 lower end of discharging spring mounting hole
The de- material needle 16 that lower end passes through positioning pressuring plate 13 is installed, discharging spring mounting hole is equipped with unloading in compressive state in 14 top
Expect spring.
16 two sides of de- material needle are vertically symmetrical to be equipped with two pilot pins 15.
Molding mother tuber 11 corresponding with flange formed punch 12 is installed on the right side of first drive block, 8 upper end, it is described at
The reception hole 19 to match with flange formed punch 12 is provided on the right side of type mother tuber 11.
Second drive block 9 is connected by link block 10 with flange formed punch 12.
Embodiment
When being molded, positioning pressuring plate 13 is moved down first, is positioned to the product in lower die station 7, is taken off simultaneously
Material pin 16 is mutually pushed up with product end surface, and pilot pin 15 passes through product, and the upper molded plate 1 of press control later moves down, 5 He of left part slotting tool
Respectively with 9 phase top of the first drive block 8 and the second drive block, the first drive block 8 and the second drive block 9 are pushing away 6 lower end of right part slotting tool
Close to lower die station 7 under the action of power, until mold fully comes together, flange formed punch 12 passes completely through product, enters reception hole 19
It is interior, it realizes a hole flanging, is opened later, the first drive block 8 and the second drive block 9 are with the first spring 17 and the second bullet when die sinking
Spring 18 is resetted, while de- material needle 16 makes product be detached from pilot pin 15 because of the elastic force of discharging spring.
