Abstract
The utility model provides a hot runner changes three -plate mold mouth of a river weight controlling means, including caster, master model benevolence and public mould benevolence, its characterized in that, the caster top is provided with hot runner mechanism, be provided with the runner between caster and the master model benevolence, the runner is the L type. The utility model discloses having reduced the length of runner and stub bar, having practiced thrift raw and other materials, reduced moreover to have improved work efficiency in the loss of in -process pressure of moulding plastics, further improved the quality and production stability of product, reduction in production cost increases mill's benefit. In addition, it protects hot runner, extension mould utility life -span to be provided with the hot runner mold insert.
Description
Technical field
The utility model relates to a kind of plasthetics manufacture field, particularly relates to a kind of hot flow path and turns three template die mouth of a river weight control devices.
Background technology
Plastic material is a kind of conventional organic material, is extensively incorporated in electronic apparatus and other digital equipment fields.Injection mo(u)lding be heated melt material inject die cavity by high pressure, after cooling curing, obtain the method for products formed.In the injection moulding production process of some products, can use the mould of Three-board-mould structure, three board molds are a kind of for having a mould of stub bar during injecting products, and three board molds comprise A plate, panel and water gap plate.Three traditional board molds are generally based on cold runner technique, the mobility of the plastics of cold runner three board mold is poor, and sprue extends to A plate from panel, and the vertical length of sprue is very long, cause stub bar also very long, not only waste material, and the regrinding-material accounting of product is comparatively large, in forming process, the pressure loss is large, cause product formation various bad, have a strong impact on quality and the injection time of product, three board molds are arranged to three board molds of hot flow path, effectively can improve the mobility of plastics.
Hot runner mould utilizes heater to make the noncondensing mould all the time of the melt in runner, because it is shorter than traditional moulds molding cycle, and economize in raw materials, so hot runner mould is in the world today, each industrially developed country and area are obtained for and apply widely.In prior art, use hot flow path to replace cold runner, add the cost of mould, but DeGrain.
For solving problems, Chinese patent 201420704308.X, disclose a kind of simple and easy mouth hot flow path three template die, comprise: the cover half assembly be equipped with up and down and dynamic model assembly, cover half assembly comprise set gradually upper mounted plate, stripper plate, solid plate and setting and solid plate in cover half core, de-material extension plate is fixed with in the middle part of described stripper plate bottom surface, de-material extension plate is arranged in solid plate and bottom surface and cover half core end face fits, and solid plate is provided with the push-and-pull hole that can hold and take off and expect that extension plate is up and down.Cover half assembly top is provided with hot flow path, and cover half assembly top is also provided with draws material pin, draws material pin bottom to insert in de-material extension plate from upper mounted plate, draws material pin end to be positioned at de-material extension plate bottom surface.The utility model newly-increased de-material extension plate, the thickness of de-material extension plate is the distance of core rod bottom surface to stripper plate bottom surface, and de-material extension plate can be tried one's best brief flow channel length, saving plastic rubber material.But, owing to arranging de-material extension plate in the utility model, add the difficulty of Design of Dies and manufacture, be unfavorable for the later maintenance of mould, improve product cost.
Summary of the invention
For solving above-mentioned Problems existing, the purpose of this utility model is to provide a kind of hot flow path to turn three template die mouth of a river weight control devices.
For achieving the above object, the technical solution of the utility model is:
A kind of hot flow path turns three template die mouth of a river weight control devices, and comprise caster, mother module core and male die core, described caster is provided with hot runner mechanism, be provided with runner between described caster and mother module core, described runner is L-type.
Again, described hot runner mechanism comprises hot flow path mold insert and Re Zui, and one end of described runner is positioned at bottom hot flow path mold insert.
Further, form die cavity between described mother module core and male die core, the other end of described runner is communicated to die cavity.
And have, be also provided with one group of lastics pin below described die cavity.
Meanwhile, described lastics needle guard is embedded in male die core.
The beneficial effects of the utility model are:
A kind of hot flow path that the utility model provides turns three template die mouth of a river weight control devices, be provided with L-type runner, reduce the length of runner and stub bar, raw material are saved, and reduce the loss of pressure in injection moulding process, improve operating efficiency, improve quality and the production stability of product further, reduce production cost, increase factory's benefit.In addition, be provided with hot flow path mold insert to protect hot flow path, extend the mold use life-span.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of hot flow path of the present utility model turns three template die mouth of a river weight control devices.
Fig. 2 is that the product structure schematic diagram obtained produced by the mould that use turns three template die mouth of a river weight control devices containing a kind of hot flow path of the present utility model.
In figure: 1 is caster, 2 is mother module core, and 3 is male die core, and 4 is hot runner mechanism, and 5 is runner, and 6 is hot flow path mold insert, and 7 is hot mouth, and 8 is die cavity, and 9 is lastics pin.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, further describe below in conjunction with drawings and Examples.
Be the structural representation that a kind of hot flow path of the present utility model turns three template die mouth of a river weight control devices see Fig. 1, Fig. 1.A kind of hot flow path of the present invention turns three template die mouth of a river weight control devices, comprise caster 1, mother module core 2 and male die core 3, described caster 1 is provided with hot runner mechanism 4, is provided with runner 5 between described caster 1 and mother module core 2, described runner 5 is L-type.
Again, described hot runner mechanism 4 comprises hot flow path mold insert 6 and hot mouth 7, and one end of described runner 5 is positioned at bottom hot flow path mold insert 6.
