Abstract

The invention discloses a mold pouring system. The mold pouring system comprises a main runner, a sub-runner, pouring gates and a cold slug well, wherein the starting point of the main runner is arranged on the contact part between a sprayer of an injection molding machine and a mold, and the end point of the main runner is arranged at the sub-runner, and is responsible for conveying plastic melt to the runner; the sub-runner is arranged on a parting surface, and is arranged between the main runner and pouring gates and is used for distributing materials conveyed by the main runner to each pouring gate, so that after the materials arrive at the sub-runner, the flowing directions of the materials are changed, and each pouring gate is a thin and short runner arranged between the sub-runner and a cavity, and is used for controlling the material flow mold filling speed and the material supplying time; the cold slug well is formed in the tail end of the main runner or is formed in the tail end of the sub-runner, and is used for storing cold slug. The mold pouring system disclosed by the invention is simple in structure, is convenient to use, and is also beneficial to improving the shaping speed to shorten the shaping cycle when the product quality of plastic finished products is met.

Description

A kind of die casting system
Technical field
The present invention relates to a kind of die casting system.
Background technology
The current heat distortion temperature to plastics by mold cavity surface heating, injected plastic then, in injection moulding process, the temperature of mould remains unchanged, after the temperature of mould drop to gradually taking-up product, next injection treatment startup, die surface heats rapidly.Mold temperature raises and reduces all very fast.
Mainly for mould.In mould die and outward appearance slide block, offer and be uniformly distributed water route, utilize high-temperature high-pressure steam for Fast Heating media, chilled water is cooling media, then uses air tracheae air pressure, sees through RHCM(high-speed and high-temperature forming technique), in plastics, add glass fibre, produce the shell with reflecting effect, RHCM can solve the product problems such as the insoluble joint line of common moulding, current mark, and equipment switches in water route in die and sliding field, heating, cooling die.
In injection front cavity and slide block, in water route, use high-temperature high-pressure steam rapidly heating moulds to higher temperature (120 degree).In injection, utilize steam to keep temperature.
In water route, stop supplying with steam in the complete die of glue and slide block, with air duct air pressure, blow clean residual aqueous vapor in water route, then turn and lead to chilled water and carry out mould fast cooling.
Drop to proper temperature, the cooling rear ejection mold-opening of product enters second circulation.RHCM equipment be equivalent to be exactly one can fast heating, cooling die fast.
Running gate system is from note machine nozzle, to start till the plastic flow passage of die cavity in mould.Running gate system is the most important in several large systems.The basic principle of design running gate system: when meeting plastic product product quality, also should be conducive to improve shaping speed and shorten molding cycle.
Summary of the invention
The defect that the present invention seeks to exist for prior art provides a kind of die casting system.
The present invention for achieving the above object, adopts following technical scheme: a kind of die casting system, comprise sprue, and its starting point is arranged on the contact site of injection molding machine nozzle and mould, and end points is arranged on runner, for being responsible for, plastic melt is transported to runner;
Runner, it is arranged on die joint, is between sprue and cast gate; For the material that sprue is sent here, distribute and transport to each cast gate, thereby material changes flow direction after runner
Cast gate, it is the one section thin short runner being arranged between runner and die cavity; Be used for regulating material stream filling mold speed and control the feed supplement time;
Cold slug well, it is opened in the end of sprue or is opened in runner end; Be used for storing cold burden.
Further, the axis of described sprue and the axis of nozzle are on a line.
Beneficial effect of the present invention: die casting system provided by the invention, simple in structure, easy to use, when meeting plastic product product quality, also help raising shaping speed and shorten molding cycle.
The specific embodiment
The present invention is designed to a kind of die casting system, comprises sprue, and its starting point is arranged on the contact site of injection molding machine nozzle and mould, and end points is arranged on runner, for being responsible for, plastic melt is transported to runner; Wherein, the axis of described sprue and the axis of nozzle are on a line.
Runner, it is arranged on die joint, is between sprue and cast gate; For the material that sprue is sent here, distribute and transport to each cast gate, thereby material changes flow direction after runner.In combination die, runner is absolutely necessary, and in one cavity mold, sometimes can save runner.
Cast gate, it is the one section thin short runner being arranged between runner and die cavity; Be used for regulating material stream filling mold speed and control the feed supplement time;
Cold slug well, it is opened in the end of sprue or is opened in runner end; Be used for storing cold burden.In injection, rest during this period of time in, nozzle of injector oral area plastics are because nozzle contacts with cold mould or contacts temperature step-down with air, make forward's cold burden of injection enter cold slug well, avoid cold burden to block cast gate or inject die cavity making product produce cold shut or cold joint seam.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
