A kind of replacing structure of die insert
Technical field
This utility model relates to die casting technical field, particularly relates to the replacing structure of a kind of die insert.
Background technology
Die casting is made up of two major parts of fixed half and moving half, the cavity that cover half and dynamic model are formed after closing up is commonly referred to die cavity, and the part constituting die cavity is forming part, forming part includes insert and core, and core is used for the hole above diecast parts or profiled shape.Owing to the working environment of die casting is more severe, in casting process, die casting (compression casting) mould is in high temperature, high pressure, high velocity environment operation, for the long-term product produced in enormous quantities, when mould invalidation such as erosion occurs, is easily cracked etc. situation, traditional method is it is generally required to change die, die fall face or the switching of how standby more molds and produce.But this kind of method switching cycle is veryer long, and can not make full use of old die and save material, mould puts into material cost and cost of manufacture is high, it is difficult to adapt to most current cost Competitive Needs.
Utility model content
The purpose of this utility model is: for the deficiencies in the prior art, and provide the replacing structure of a kind of die insert, and this replacing structure realizes when mould invalidation being switched fast production, improving stock utilization, reduction mold materials input and cost of manufacture.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of replacing structure of die insert, including die, standard insert and replacing insert, described die has insert groove, described standard insert is identical with the structure of described replacing insert, it is provided with core structure, described standard insert and described replacing insert in described standard insert and described replacing insert all can be embedded in described insert groove.
As a kind of improvement of the present utility model, also including that screw rod, described die have the screw hole connected with described insert groove, described die is connected with described standard insert or the fastening of described replacing insert through described screw hole by described screw rod.
As a kind of improvement of the present utility model, described insert groove is set to square structure, and described screw hole is likewise provided as four, and four described screw holes are distributed in the corner of described insert groove.
As a kind of improvement of the present utility model, the quantity of described insert groove is set at least two, and the structure of each described insert groove is the most identical.
Compared with prior art, the beneficial effects of the utility model are: this utility model includes die, standard insert and changes insert, described die has insert groove, described standard insert is identical with the structure of described replacing insert, it is provided with core structure, described standard insert and described replacing insert in described standard insert and described replacing insert all can be embedded in described insert groove.This utility model is by realizing exchanging by standard insert and replacing insert;When losing efficacy occurs in current a set of insert, only need to replace standard standby replacing insert, process without changing whole die or mould fall face, owing to the volume and fabrication cycle changing insert is little more than whole die, thus reach to save material cost and quick Fabrication and the purpose of maintenance.
By description below and combine accompanying drawing, this utility model will become more fully apparent, and these accompanying drawings are used for explaining embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is decomposing schematic representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
Detailed description of the invention
Referring to figs. 1 to Fig. 2, a kind of replacing structure of die insert, including die 1, standard insert 2 and replacing insert 3, die 1 has insert groove 4, standard insert 2 is identical with the structure changing insert 3, thus realize the quick-replaceable of standard insert 2, it is provided with core structure 7 in standard insert 2 and replacing insert 3, its cinder ladle, air bleeding valve, feeding mouth all design at die 1, so insert sectional area can accomplish minimum, maximum can save material, standard insert 2 and replacing insert 3 all can be embedded in insert groove 4.
This utility model also includes that screw rod 6, die 1 have the screw hole 5 connected with insert groove 4, and die 1 is fastened and is connected through screw hole 5 with standard insert 2 or replacing insert 3 by screw rod 6.
Preferably, insert groove 4 is set to square structure, and screw hole 5 is likewise provided as four, and four screw holes 5 are distributed in the corner of insert groove 4.The quantity of insert groove 4 is set at least two, and the structure of each insert groove 4 is the most identical.
When mould produces, according to order state and upper a set of insert, standard insert 2 or replacing insert 3 can estimate that the cycle lost efficacy makes in advance.When in producing, losing efficacy such as erosion, be full of cracks etc. occurs in the standard insert 2 of mould, it is not necessary to the replacing insert 3 got ready, in order produces, only need to be replaced, i.e. can reach the purpose quickly resumed production by the mode of fall face or replacing die 1 that carries out again.
It should be understood that die 1 needs about 20 days before and after changing after actual measurement existing mold erosion, fall face is also required to about 10 days, and this utility model does exchange insert and only needs 2 hours can again go up machine die trial.It addition, through measuring: more transducer set 1*2 die 1 specification is 370.0*230.0*74.5, and 2 pieces of insert specifications are 99.0*99.0*33.30, and consumptive material demand percentage is about 10:1.Visible, this utility model realizes when mould invalidation being switched fast production, improving stock utilization, reduction mold materials input and cost of manufacture.
Above in association with most preferred embodiment, this utility model is described, but this utility model is not limited to embodiment disclosed above, and amendment, the equivalent combinations that the various essence according to the present embodiment is carried out should be contained.
