Detailed description of the invention:
The mould structure that square curved pin drives circular curved pin to loose core as shown in the figure, its operating principle is: when after die casting moulding, after die casting machine driven mold dynamic model part, move, in this die sinking process, goods are pulled to dynamic model one side, the square curved pin (13) that is simultaneously arranged on cover half one side moves the translation motion that forces the curved pin of circle (22) being arranged in slide block (9) to make mould lateral direction after with mould dynamic model part, and do in lateral direction translation motion at the curved pin of circle (22), the sweep of circular curved pin (22) forces the first core (26) to the action of mould dynamic model direction below, the moulding section that extend into the first core (26) in cinclides inside goods in This move is extracted out from goods hole, after the first core (26) is extracted out from the areole of goods inside, at this moment square curved pin (13) is deviate from from the inclined hole of the curved pin of circle (22), so circular curved pin (22) is no longer action under the restriction of alignment pin (14).Now high pressure gas enters in pneumatic cylinder (24), the slide block (9) that piston driving in high pressure gas promotion pneumatic cylinder (24) is connected on piston is made translation motion to mould lateral direction, because slide block (9) is to the translation of mould lateral direction, so two boss of product molding on slide block (9), deviate to be arranged on the spill place of slide block (9) front end, pneumatic cylinder (24) continues band movable slider (9) and does the action of mould lateral direction, at this moment the moulding section of the slide block of moulded products endoporus (9) exits completely from goods, ensureing behind the gap that has foremost 3-4mm of goods and slide block (9) simultaneously, at this moment pneumatic cylinder (24) stops action.And mould dynamic model part is moved after continuing, when die sinking spacing is greater than after goods and running gate system clout height overall, mould dynamic model part stops action, and at this moment die casting machine push rod promotion push rod backing plate (2) drives the push rod (1) being arranged on pusher plate (4) outside goods launch mode.Complete after one-time cast-forming, when matched moulds, first be that die casting machine push rod retreats, contrary action in the time being mounted in the second spring (3) between pusher plate (4) and mavable module core and forcing pusher plate (4) to drive push rod (1) to do die sinking, after push rod (1) resets completely, high pressure gas enters in pneumatic cylinder (24) and drives piston to do the action of side direction in mould, because piston is done the action of side direction in mould, so the slide block (9) being connected on piston completes reset, when slide block (9) completes after reset, piston in pneumatic cylinder stops action, dynamic model part while continuing to do die sinking contrary action close to cover half direction, at this moment the square curved pin (13) that is arranged on cover half side inserts in the inclined hole on circular curved pin (22), mould dynamic model part continues to move to cover half direction, now square curved pin (13) forces circular curved pin (22) to side direction action in mould, in This move process, circular curved pin (22) forces core (26) to reset, after respectively opening part and resetting completely, mould is just made next cycle moulding by casting, more than action comes and goes and carries out, to meet the batch production of goods.
