Description
Technical field
The utility model relates to a kind of mould, particularly relates to a kind of mould for thin wall circular cylindricality aluminium alloy castings.
Background technology
Major part annulus cylindrical body needs due to design technology and equipment, and bottom ring part wall thickness has problems, and the wall thickness produced due to this type of is excessively thin, makes product cannot find a suitable position, carries out injection pan feeding; Because wall thickness is excessively thin, most of annulus cylindrical body and mold bottom contact surface are also corresponding is very thin, cannot find suitablely to eject position after making formed product.Because excessively thin wall thickness causes product weakness to become fragile, easily collapse and lack easily, fracture, thus outward appearance and the yields of product can be affected.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of mould for thin wall circular cylindricality aluminium alloy castings of new structure, make it have more value in industry.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of mould for thin wall circular cylindricality aluminium alloy castings.
A kind of mould for thin wall circular cylindricality aluminium alloy castings of the present utility model, comprise quiet template, cavity plate and moving platen, described cavity plate is provided with a die cavity, described die cavity is that annulus column construction is arranged, the described cavity bottom of annulus cylindricality is provided with an extension ring wall, extending ring wall is that circular arc is arranged, the bottom of die cavity is made to be horn-like layout, the altitude range of described extension ring wall is at 0.4 ~ 0.6mm, the width range of described extension ring wall is at 0.3 ~ 0.5mm, the runner cavity plate be connected with described die cavity offering cast gate and be connected with cast gate, described runner is distributed in the periphery extending ring wall.
Further, the scope of described extension ring wall circular arc is at 120 ° ~ 150 °.
Further, described runner is in " Y " type structural configuration, and the first half of its " Y " type is that circular arc is arranged, and is matched with the periphery extending ring wall.
Further, described cavity plate is provided with thimble, described thimble is distributed in just to extension ring wall.
Further, described thimble is fan-shaped layout, matches with extension ring wall.
Further, the length of described runner accounts for and extends 1/3 of ring wall length.
Further, the height of described extension ring wall is preferably at 0.5mm.
Further, the width of described extension ring wall is preferably at 0.4mm.
By such scheme, the utility model at least has the following advantages:
The utility model by extend ring wall and runner with the use of conveniently filling injection molding material, ejecting product can also be facilitated by increasing extension ring wall in the bottom of die cavity simultaneously, use fan-shaped thimble can eject effective, safe fast for product, and make it to there will not be breach, ensure the quality of product, reduce costs.Increase extended loop wall energy for various dissimilar thin wall circular column construction.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation after formed product of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
See Fig. 1 and Fig. 2, a kind of mould for thin wall circular cylindricality aluminium alloy castings described in the utility model one preferred embodiment, comprise quiet template, cavity plate 1 and moving platen, described cavity plate 1 is provided with a die cavity 2, described die cavity 2 is annulus column construction layout, an extension ring wall 21 is provided with bottom the die cavity 2 of described annulus cylindricality, extend ring wall 21 to arrange in circular arc, the bottom of die cavity 2 is made to be horn-like layout, the altitude range of described extension ring wall 21 is at 0.4 ~ 0.6mm, the width range of described extension ring wall 21 is at 0.3 ~ 0.5mm, the runner 3 cavity plate 1 be connected with described die cavity 2 offering cast gate and be connected with cast gate, described runner 3 is distributed in the periphery extending ring wall 21.
Wherein, the height of described extension ring wall 21 is preferably at 0.5mm, the width of described extension ring wall 21 is preferably at 0.4mm, the scope extending ring wall circular arc 21 is preferred at 120 ° at 120 ° ~ 150 °, the mode adopting this kind to select maximizedly can ensure that product there will not be breach, also can ensure that product can eject effective, safely fast simultaneously.
Described runner 3 is in " Y " type structural configuration, the first half of its " Y " type is that circular arc is arranged, and be matched with the periphery extending ring wall 21, and the length of runner 3 accounts for 1/3 of extension ring wall 21 length, be set to and account for 1/3 runner 3 length and can realize fast injection molding, and the structure of cavity plate 1 pair of die cavity 2 can not be had influence on.
