Description
Technical field
The present invention relates to a kind of processing mold of friction plate of brake block.
Background technology
Brake block can be divided into two kinds in the market, a kind of is to add directly friction plate and steel backing hot pressing to be pasted man-hour, another kind is first that friction plate is hot-forming, then holes at the friction plate of moulding, at last steel backing and friction plate is fixed in drill hole by screw or rivet.Although the latter has the more firm advantage of connection, because the problem of friction plate material very easily damage friction plate when boring, thereby percent defective is higher.
Summary of the invention
For the deficiency that prior art exists, the object of the present invention is to provide a kind of processing mold of friction plate of brake block of Effective Raise finished product rate.
For achieving the above object; the invention provides following technical scheme: a kind of processing mold of friction plate of brake block; comprise the upper die mechanism that is cascading from top to bottom; middle mold mechanism and lower mold mechanism; described middle mold mechanism comprises the middle mould body that is the tabular setting; be provided with the friction plate forming cavity on the middle mould body; described friction plate forming cavity is up and down penetrating being arranged on the described middle mould body; described upper die mechanism comprises location-plate and pressing plate; described location-plate parallels setting with middle mould body; described pressing plate is set in parallel in the relatively middle mould body opposite side of location-plate; corresponding location-plate one side of described pressing plate is fixedly installed contact pin; and described contact pin is arranged on corresponding friction plate forming cavity position; be provided with suitable with contact pin on the described location-plate and pass and extend to through hole in the friction plate forming cavity for the top of contact pin; the locating part of the length when also being provided with restriction contact pin top between described pressing plate and the location-plate and extending in the friction plate forming cavity; the die head that described lower mold mechanism comprises base plate and is arranged on mould body one side in the base plate correspondence; described die head shape and the suitable setting of friction plate forming cavity shape; and die head is arranged on corresponding friction plate forming cavity position, is provided with elastic supporting member for supporting optical member between described middle mould body and the base plate.
By adopting technique scheme, friction plate to brake block adds man-hour, in the bottom of die head top section engaging friction sheet forming cavity, in the friction plate forming cavity, add the friction plate dusty material, because in the bottom of die head top section engaging friction sheet forming cavity, friction plate material can not revealed by the bottom; Then press down pressing plate, the upper wall of location-plate and middle mould body is affixed; Continue to press down pressing plate, this moment, contact pin passed in the through hole engaging friction sheet forming cavity, pressing plate presses to locating part when spacing to it, mold mechanism moved down during upper die mechanism drove, die head carries out hot-forming to the friction plate material in the friction plate forming cavity, the corresponding contact pin of the friction plate of moulding position just has for the through hole that usefulness is installed; At last; discharge the pressure of pressing plate; middle mold mechanism is owing to the effect of elastic supporting member for supporting optical member moves up; contact pin withdraws from the friction plate forming cavity simultaneously; again upper die mechanism is moved on the whole, the upper wall surface of location-plate and middle mould body is separated, and then middle mold mechanism is pressed down; die head is ejected the friction plate in the friction plate forming cavity, obtain having the friction plate of installing with through hole.
The present invention further arranges: described locating part is set to flange, and described flange is arranged on the location-plate and to pressing plate direction projection, described contact pin length is greater than the height setting of flange.
By adopting technique scheme, the height that the length of contact pin and flange can be set according to the thickness of processed friction plate adds the difference of the thickness of location-plate.
The present invention further arranges: be provided with spring between described location-plate and the pressing plate, the length during described spring undeformed is greater than the height of described flange.
By adopting technique scheme, so that contact pin and pressing plate can reset smoothly.
The present invention further arranges: also be provided with the guide rail that pressing plate is moved along the direction vertical with location-plate between described location-plate and the pressing plate.
By adopting technique scheme, can guarantee that pressing plate and contact pin move along the vertical direction of location-plate, improve the molding effect of friction plate.
The invention will be further described below in conjunction with accompanying drawing.
