Description
Technical field
The present invention relates to plastic machining mold.
Background technology
Injection moulding is a kind of method of industrial products production moulding.Product uses rubber injection mold and plastics injection moulding usually.Injection moulding also can divide injection mould platen press and casting die.Injection (mo(u)lding) machine (being called for short injector or injection machine) thermoplastic or thermosetting plastics is utilized mould for plastics to make the main former of the plastic products of various shape, and injection moulding is realized by injection machine and mould.Product is widely used in: the industry such as mobile phone, laptop computer, multiple plastic shell, communication, micro machine, computer, electrical equipment, electronics, toy, clock and watch, lamp decoration, locomotive.Injection mold is the instrument producing plasthetics, is also the instrument giving plasthetics complete structure and accurate dimension.A kind of processing method used when injection mo(u)lding is some complex-shaped parts of batch production, specifically refers to the material melted that is heated to inject die cavity by high pressure, after cooling curing, obtains formed products.
Along with the day by day maturation of injection molding technology, increasing plastic cement products can be produced by injection moulding, and simultaneously also more and more higher to the requirement of mould, mould is generally divided into dynamic model and cover half, treats that foundry goods is shaping, and dynamic model moves opens die cavity, is exposed by foundry goods and then takes off; For the shaft-like foundry goods that some are thinner, if simple employing dynamic model positioned opposite and the cover half demoulding, foundry goods unbalance stress can be made, easily cause casting deformation to be torn or directly rupture.
Summary of the invention
The invention is intended to provide a kind of avoids elongated foundry goods to deform the diclinic bar casting mold of fracture.
Diclinic bar casting mold in this programme, comprise fixed half and moving half, described fixed half and moving half is fitted formation die cavity relatively, die cavity is provided with sprue gate, cylinder is connected with between described dynamic model and cover half, the cylinder seat of cylinder is connected with cover half, the output of cylinder is connected with dynamic model, described cover half is provided with the upper brace be positioned at above die cavity and the lower brace be positioned at below die cavity, dynamic model is provided with the upper saddle be positioned at above die cavity and the lower slider be positioned at below die cavity, upper saddle and lower slider are slidably connected on dynamic model, upper saddle and lower slider are all provided with the through hole holding brace and pass, upper saddle and lower slider are respectively equipped with upper cavity plug and lower mode cavity plug near one end of die cavity, described upper cavity plug and the shutoff of lower mode cavity plug are being located in the opening on die cavity side, the face that die cavity upper mouth is relative is provided with push rod, push rod passes dynamic model and extends in die cavity.
Beneficial effect: cast starts, dynamic model and cover half close, and upper saddle and lower slider push against to die cavity direction, upper cavity plug and lower mode cavity plug is made to block opening on die cavity side, mould-injection fused solution is watered in die cavity, to be cast shaping after, start cylinder and push dynamic model open, dynamic model and cover half are laterally separately, upper brace and lower brace promote on upper saddle and lower slider respectively, lower slider, make upper cavity plug and lower mode cavity plug and die cavity separately, realize the demoulding on workpiece three directions, make stress dispersion suffered by workpiece, not easy fracture, so the demoulding is stablized feasible more, when the demoulding completes, now workpiece is still bonded on dynamic model, promotes push rod, is ejected by workpiece, workpiece is come off.Such scheme, for the problem of the thinner shaft-like foundry goods easy fracture of cast, by the demoulding simultaneously on three directions, is avoided the stress of cast(ing) surface too concentrated, is made the demoulding of foundry goods more stable, effectively avoid rupturing during the workpiece demoulding.
Further, diclinic bar casting mold, it is characterized in that: above described upper saddle, be provided with wedge, the below of lower slider is provided with lower wedge, upper wedge is all provided with the inclined-plane identical with described brace gradient with on lower wedge, the inclined-plane of upper saddle and upper wedge fits, and the inclined-plane of lower slider and lower wedge fits.Wedge and lower wedge are set, certain supporting role can be played to upper saddle, lower slider, upper saddle, lower slider are slided more stable, so increase mold releasability reliability.
Further, described upper saddle, lower slider are provided with boss near one end of upper cavity plug, lower mode cavity plug, and this boss is sandwiched in the stopper slot being located at die cavity outside, carries out spacing to boss, prevent upper cavity plug, lower mode cavity plug from offseting, cannot opening on shutoff die cavity side.
Further, described push rod is connected with slide block away from one end of die cavity, dynamic model is laterally provided with slide bar, slide bar makes slide block slide on slide bar through slide block, and slide block is provided with away from the side of die cavity the baffle plate limiting slide position, and slide bar leads to push rod, push rod is made to move steadily, the movement of baffle plate to push rod is spacing, and make push rod release end and just go out die cavity, the drive end of push rod reaches baffle position.
Further, described upper wedge and lower wedge are connected on cover half respectively by bolt, and cross bar bolt is connected on dynamic model, and bolt connects reliable, and detachably, is convenient to dismounting.
