Specific implementation mode
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase It mutually combines, the utility model is described in further detail in the following with reference to the drawings and specific embodiments.
If directional instruction in the utility model embodiment(Such as up, down, left, right, before and after ...)It is only used for explaining In a certain particular pose(As shown in the picture)Under relative position relation, situation of movement etc. between each component, if the specific appearance When state changes, then directionality instruction also correspondingly changes correspondingly.
If in addition, the description for being related to " first ", " second " etc. in the present invention is used for description purposes only, and cannot manage Solution is instruction or implies its relative importance or implicitly indicates the quantity of indicated technical characteristic.Define as a result, " the One ", the feature of " second " can explicitly or implicitly include at least one of the features.
Fig. 1 ~ 4 are please referred to, the utility model embodiment proposes a kind of stretching automatic stripping mold, including upper mold 10, punching First 20, lower die 30, demoulding sliding block 40, return springs 50 and baffle 60, wherein 40 inside of the demoulding sliding block offers tiltedly Face;When die stroke, punch 20, which squeezes inclined-plane, makes demoulding sliding block 40 move backward, and when mold backhaul, demoulding sliding block 40 is resetting Punch is resisted under the action of elastic component 50, realizes automatic demoulding.
The slope of the demoulding sliding block 40 is 45 degree of -75 degree.As a preferred embodiment, in the present embodiment Gradient be 45 degree.
The gap of the lower die 30 and demoulding 40 slide fit of sliding block, the lower die 30 and demoulding 40 slide fit of sliding block is 0.01mm, The limit protrusion 41 that the demoulding sliding block 40 is equipped with, the limit protrusion 41 make the inclined-plane of demoulding sliding block 40 be located at the punching of punch 20 Within the scope of journey.It should prevent demoulding sliding block 40 from existing designed in product drawing process, limiting the motion track of demoulding sliding block 40 Deviate under the action of punch 20.
The mold further includes upper die plate 70, lower mold backing plate 80 and guide post 90, and the drafting angle of the punch 20 is 0 Degree, the upper mold 10 are installed in upper die plate 70 by screw, and the lower die 30 is installed in lower mold backing plate 80 by screw.Due to The drafting angle of mold and punching head 20 is 0 degree so that punch 20 is easily worked, and needs to be also easier to when detected size, 20 He of punch The pressure that lower die 30 is born becomes smaller, and to extend the service life of mold, the precision of product is high, reduces the allowance of CNC, The process time in CNC techniques and cost can be reduced.
The lower mold backing plate 80 offers clearance position, and the width of the clearance position is more than the product 1mm-3mm that is stretched.As The width of a kind of preferred embodiment, the utility model clearance position is more than the product 1mm that is stretched, which falls convenient for product.
The upper mold 10 is positioned with lower die 30 by guide post 90, and very high stroke precision can be reached, and ensures stamping products Precision.
In the present embodiment, the demoulding sliding block 40 is in dove-tail form, is play the guiding role when with 30 slide fit of lower die.
The return springs 50 are spring or elastic plastic.In the present embodiment, the return springs 50 are spring.
Workflow:
When die stroke, 20 downward stamping products of punch, product moves down after the stamping press by punch 20, due to de- The part that mode slider 40 is contacted with product is equipped with inclined-plane, and product moves down during pushing along the inclined-plane of demoulding sliding block 40, It demoulds the pressed home elastic component 50 under the action of product of sliding block 40 simultaneously to move backward in the horizontal direction, the baffle 60 of both sides is used It is popped up by the extruding of demoulding sliding block 40 in preventing return springs 50.When 20 downward conduct of punch reaches maximum, demoulding Sliding block 40 to middle slip and supports punch 20 under the action of return springs 50.When mold backhaul, product is with punch 20 1 It rises and moves up, when product is moved to demoulding sliding block 40, product is withstood in the lower end of demoulding sliding block 40, and product is made to divide with punch 20 From achieving the effect that automatic demoulding.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied Change, replace and modification, the scope of the utility model are limited by appended claims and its equivalency range.
