Detailed description of the invention:
The mold mechanism that circular hole taken out by metal die-casting mold connecting rod as shown in the figure, this mould is special due to foundry goods, as adopted the core-pulling mechanism of traditional dies to form mould, be difficult to the shaping of foundry goods each several part and loosed core, therefore this mould is according to the particularity of foundry goods, when mould molding, loose core in the curved hole that the bent tube section of foundry goods adopts connecting rod band movable slider to complete on it, the threaded portion on foundry goods adopts gear to rotate inner threaded core-pulling.Its mold actions principle is: after on clamping mould to horizontal plunger die casting machine, adjust mould dynamic model, the position relationship of cover half on die casting machine, after empty mold repeatedly checks that whether each position is flexible, and then matched moulds, through moulding by casting, pressurize feeding, after cooling and shaping, die casting machine driven mold dynamic model part is drawn back, mould dynamic model part and cover half partially open, now foundry goods is pulled to dynamic model one side from the die cavity of fixed mold core (50), in this course, the connecting rod (45) be arranged on top clamping plate drives slip (40) of loosing core in the Circular Sliding groove of slide (41), do the spinning movement in outer direction on the right side of mould, due to the action of core-pulling slide block (40), the moulding section of core-pulling slide block (40) is forced to separate with the Inner arc hole of foundry goods, after treating that the moulding section of core-pulling slide block (40) is all extracted out from circular hole, and after ensureing that foundry goods circular arc portion and core-pulling slide block (40) moulding section have the spacing of 7-8mm, die casting machine stops action.While This move, running gate system is cut off from the forming cavity of fixed mold core (50) and separates with foundry goods, and running gate system drops out outside mould by deadweight with dynamic model and cover half opening clearance.After the solidifying material of running gate system completes the demoulding, now die casting machine central ejector rod promotes connecting axle (10) and rotates under the revolving force of clutch shaft bearing (11) and the second bearing (23), and drive the second gear (8) be arranged on connecting axle (10) to rotate, second gear (8) drives the first gear (22) be arranged on the second core (20) to rotate, because the rotation of the second core (20) is deviate from regard to forcing the internal thread on foundry goods, in the This move deviating from internal thread, the edge push rod of die casting machine promotes cushion block (14) and drives the 3rd core (24) outside foundry goods launch mode.During matched moulds, mould is done after the contrary action of die sinking completes the reset of respectively opening profile, and just locking enters the moulding by casting in next cycle.
