Summary of the invention
The object of this invention is to provide a kind of simple to operate and the injection mold forced stripper mechanism device of quick matched moulds and the demoulding can be played.
To achieve these goals, injection mold forced stripper mechanism device provided by the invention, comprise patrix, counterdie, demoulding block and demoulding fork, described upper die and lower die inside is fixedly installed the patrix insert and counterdie insert that are matched to moulding cavity, described counterdie is provided with the injection molding gun passing into cavity, described demoulding block comprises locating piece and sliding shoe, described patrix is provided with the block offseted with counterdie horizontal direction, described demoulding fork one end is hinged on patrix, the other end is hinged on sliding shoe, and on patrix and sliding shoe, be provided with oscillating stroke groove, described locating piece and counterdie are fixed, described counterdie is provided with vertical sliding pin, patrix arranges and is combined with cotter way with sliding pin, described sliding shoe is fixedly connected with line shaft.
The injection mold forced stripper mechanism device of this programme when in use, sliding shoe is promoted by line shaft at knockout course, sliding shoe is moved to locating piece direction, now swing knockout pin and become vertical from inclination gradually, patrix is moved up, owing to being provided with vertical sliding pin and the cotter way of cooperation between upper die and lower die, locating piece and block vertical direction offset, make patrix upward vertical movement, extruding force can not be produced to moulding at knockout course patrix, make the integrality of moulding.
The invention has the advantages that: swing knockout pin two ends are hinged on patrix and sliding shoe respectively, and realize moving both vertically of patrix in conjunction with the cooperation of sliding pin and cotter way, and matched moulds and the demoulding are all controlled by sliding shoe, make to control the quick matched moulds of simple realization and the demoulding.
As preferred scheme, described patrix is provided with fork fixed block and a upper cover, and described upper cover is fixed by bolt and patrix, and described fixing swinging block is fixed by upper cover and patrix, and the detachably hinged bar of described fork is fixed on fixing swinging block.Thisly be designed with the dismounting being convenient to patrix, if when will dismantle patrix, as long as taken away by upper cover, patrix can be decorporated by the toggle taking off fixing demoulding fork.
As preferred scheme, be provided with mutually chimeric spacing preiection and direction recess between described locating piece and sliding shoe, by the cooperation of spacing preiection and direction recess, the stroke namely determining sliding shoe also eliminates the changing of the relative positions between locating piece and sliding shoe.
As preferred scheme, described locating piece is provided with chimeric spigot surface near line shaft, and patrix is provided with guide pad, the inclined-plane that on described guide pad, setting and locating piece coordinate, in matched moulds process, by guide pad, sliding shoe and locating piece are compressed, upper die and lower die are connected closely.
Finally, described counterdie end is provided with the supporting seat preventing line shaft from swinging, and is carried out the stroke guiding of line shaft, prevent line shaft from occurring dancing by supporting seat.
