Description
Technical field
The present invention relates to injection-moulding plastic and die cast metal moulding, is the mould of connecting rod, the disconnected cast gate of lever sled.
Background technology
The cast gate using on injection-moulding plastic and die cast metal mould has following several form: (1) drop gate, is characterized in: melt directly enters die cavity by sprue, and flow process is short, charging is fast, and flow resistance is little, and transmission of pressure is good, pressurize feeding effect is strong, be conducive to exhaust and eliminate weld mark, but remove cast gate inconvenience, on goods, have obvious gate vestiges, cast gate position heat is concentrated, late, internal stress is large, easily produces pore and shrinkage cavity in die cavity sealing.(2) trumpet assembly: it is the variant form of drop gate, and melt directly flows to die cavity from center.It has the merits and demerits of drop gate.(3) side gate: it cries again edge-gated, side gate is opened on the die joint of mould, from the charging of goods lateral edge.It can adjust gate size easily, control shear rate and cast gate off-period, but housing component exhaust is inconvenient, easily produces weld mark, shrinkage cavity and pore.(4) spot pouring mouth: claim again pin gate, it is the drop gate of the special shape that a kind of feed gap dimension is very little.Its advantage is to remove after cast gate, and the vestige staying on goods is not obvious, can automatic breaking after die sinking, during moulding, can reduce weld mark, but the pressure loss is large, and shrink of product is large, and mould structure is complicated, causes mould installation, debugging, inconvenient maintenance.Die manufacturing cycle is long, and die cost is high.(5) sub marine gate: be again tunnel gate or shearing pouring gate, this sprue channel is arranged on die joint, cast gate is located at the position that goods side does not affect outward appearance, and become a 45° angle degree with runner, slip into below die joint or above the oblique die cavity that enters, formation can be cut off the edge of a knife of cast gate, during die sinking, the solidifying material of runner is released by ejecting mechanism, and automatically cuts off with goods.But this cast gate, due to when the solidifying material of pushing out product and runner, must have larger thrust, and therefore this cast gate is not suitable for tough plastic shaping.The deficiency existing in order to solve above-mentioned several cast gate, I manufacture line experience for many years in conjunction with mould, and spy provides following a kind of mould to solve the problems referred to above.
Summary of the invention
The present invention is to provide the mould of connecting rod, the disconnected cast gate of lever sled, this model's point is: utilize the pallet (20), connecting rod (5), the lever (4) that are arranged on stationary mould for mould one side, when die sinking, be arranged on dynamic model one side's drag hook (6) drivening rod (5) action, because forcing lever (4), the effect of connecting rod (5) drives lifting of pallet (20), lifting of pallet (20), the solidifying material prizing in the runner of running gate system is deviate from runner, so goods (17) are broken with the pin gate place in running gate system, reach the object of cutting off cast gate.It is graceful that this mold mechanism is of value to products appearance quality, is of value to mould manufacture, installation, debugging, easy to maintenance.The mould of the disconnected cast gate of connecting rod, lever sled, has solved drop gate and has removed cast gate inconvenience, has obvious gate vestiges on goods, and cast gate position heat is concentrated, and sealing late, internal stress greatly, easily produces the problem of pore and shrinkage cavity.Solve side gate exhaust bad, easily produced the problem of shrinkage cavity and pore.Solved the spot pouring mouth pressure loss large, shrink of product is large, the problem of mould structure complexity.Solved the problem that tunnel gate is not suitable for tough plastic shaping.Connecting rod, the mould of the disconnected cast gate of lever sled, it is characterized in that: sprue bush (11) is fastened in top clamping plate (2), spring (21) is arranged in the hole between top clamping plate (2) and solid plate (19), guide pillar (18) and top clamping plate (2), solid plate (19) matched in clearance, connecting rod (5) is flexibly connected with lever (4), pallet (20) is fastenedly connected with lever (4), drag hook (6) is fastened on dynamic model backing plate (8) with the first screw (11) and the second screw (12), core (16) coordinates with moving platen (7) glade plane space, push rod (13) is fastenedly connected with push pedal (15), moving platen (7), dynamic model backing plate (8), mould pin (10), Bottom clamp plate (9) is fastenedly connected to be integrated and forms dynamic model part.

The specific embodiment:
The mould of connecting rod, the disconnected cast gate of lever sled as shown in the figure, this model's point is: utilize the pallet (20), connecting rod (5), the lever (4) that are arranged on stationary mould for mould one side, when die sinking, be arranged on dynamic model one side's drag hook (6) drivening rod (5) action, because forcing lever (4), the effect of connecting rod (5) drives lifting of pallet (20), lifting of pallet (20), the solidifying material prizing in the runner of running gate system is deviate from runner, so goods (17) are broken with the pin gate place in running gate system, reach the object of cutting off cast gate.This mould operation principle is: when clamping mould is to injector or die casting machine, through moulding by casting, pressurize feeding, after cooling and shaping, mould dynamic model part partially opens with cover half, injector or die casting machine drive dynamic model to move backward, in the process moving at this, when the drag hook (6) that is arranged on dynamic model one side is collided with connecting rod (5), pressure drivening rod (5) action of drag hook (6), the action of connecting rod (5) forces lever (4) to drive pallet (20) upwards to lift, due to lifting of pallet (20), so the solidifying material (3) of running gate system is lifted, This move is just disconnected the solidifying material (3) of goods (17) and running gate system sled, the solidifying material of running gate system (3) that sled is had no progeny drops out outside mould by deadweight from top clamping plate (2) and the die sinking gap of solid plate (19).After dynamic model continues, move, when die sinking is apart from being greater than after goods height, dynamic model stops action, at this moment push rod (14) promote push pedal (15) drive push rod (13) goods (17) from core (16) outside launch mode.After one-shot forming, when mould resets, the contrary action while driving dynamic model partly to do die sinking of injector or die casting machine, so drag hook (6) drivening rod (5) forces lever (4) to drive pallet (20) to reset.Continue matched moulds, when moving platen (7) and solid plate (19) are collided, the pressure of moving platen (7) forces solid plate (19) return.After respectively opening the complete closure of profile, injector or die casting machine just carry out the moulding by casting in next cycle.
