We, which have developed, thus a kind of can solve the problems such as product surface flash, overlap；Meanwhile it is bad to solve exhaust
The problems such as bubble of appearance, air pocket, starved；Simple in structure, good product quality and stabilization can be produced with standard batch, be added
Work is at low cost, the high overflow-type injection mold of production efficiency.
Invention content
Being there is provided the invention aims to overcome the deficiencies in the prior art a kind of can solve product surface flash, overlap
The problems such as；Meanwhile solving the problems such as bubble, air pocket, starved for being vented bad appearance；It is simple in structure, good product quality and steady
It is fixed, it can be produced with standard batch, processing cost is low, the high overflow-type injection mold of production efficiency.
In order to achieve the above objectives, the technical solution adopted by the present invention is：Overflow-type injection mold, including front cavity and rear mold
Benevolence；It is provided with cavity in the rear cavity；It is provided with inserts in the cavity；The rear portion of the inserts is provided with the first plug-in unit；
The second plug-in unit is provided in the front cavity；Second plug-in unit is inserted into the groove of the front of inserts；The front cavity is with after
Mode is fixed by screw；It is provided with sealing ring in gap between the inserts and cavity；The sealing ring and the second plug-in unit
Between be provided with silicon rubber.
Preferably, the surface of the rear cavity is provided with into glue groove and excessive glue groove；Described one end into glue groove connects with cavity
Logical, the other end is connected to excessive glue groove.
Preferably, the inserts is iron inserts or hard plastic part.
Preferably, the sealing ring is made of high-temperature-resistant flexible material.
Preferably, the sealing ring is in semi-circular shape or circular ring shape or half elliptic or ellipse or half square or rectangular.
Due to the application of the above technical scheme, the present invention has following advantages compared with prior art：
Overflow-type injection mold of the present invention solves the problems such as product surface flash, overlap, also product surface is made more to float
It is bright；Meanwhile solving the problems such as bubble, air pocket, starved for being vented bad appearance；The configuration of the present invention is simple, good product quality and
Stablize, can be produced with standard batch, processing cost is low, and production efficiency is high.
Description of the drawings
Technical scheme of the present invention is further explained below in conjunction with the accompanying drawings：
Attached drawing 1 is the sectional view of overflow-type injection mold of the present invention；
Attached drawing 2 is the vertical view of the rear cavity of overflow-type injection mold of the present invention；
Attached drawing 3 is the enlarged drawing in the portions A in attached drawing 1；
Wherein：1, sealing ring；2, silicon rubber；3, inserts；4, into glue groove；5, excessive glue groove；6, front cavity；7, rear cavity；8, cavity；
9, the first plug-in unit；10, the second plug-in unit.
Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment, the present invention is described in further details.
Attached drawing 1-3 is overflow-type injection mold of the present invention, including front cavity 6 and rear cavity 7；In the rear cavity
It is provided with cavity 8；Inserts 3 is provided in the cavity 8；The rear portion of the inserts 3 is provided with the first plug-in unit 9；The front cavity 6
Inside it is provided with the second plug-in unit 10；Second plug-in unit 10 is inserted into the groove of the front of inserts 3（It does not mark）It is interior；The front cavity 6
Pass through screw with rear cavity 7（It does not mark）It is fixed；The surface of the rear cavity 7 is provided with into glue groove 4 and excessive glue groove 5；It is described into
One end of glue groove 4 is connected to cavity 8, and the other end is connected to excessive glue groove 5；It is provided in gap between the inserts 3 and cavity 8
Sealing ring 1；It is provided with silicon rubber 2 between the sealing ring 1 and the second plug-in unit 10.
The inserts 3 is iron inserts or hard plastic part；The sealing ring 1 is made of high-temperature-resistant flexible material.
In the present invention, since silicon rubber is liquid form at normal temperatures, mobility is very good, after high temperature vulcanized, is solidified into
Solid shape, silicon rubber formed mainly have separately formed, and two kinds of forms of mixed-forming, mixed-forming has soft or hard glue to be mixed into again
The forms such as type, flexible glue and ironware mixed-forming；So when silicone rubber products are molded, outside place that all runners connect, cavity
Equal places will be sealed using sealing ring, ensure that fluid silicone rubber will not leak, and in mixed-forming, ebonite and ironware
Equal inserts are after advance comprising is good again with silicon rubber mixed-forming, and inserts has gap in cavity, if product cavity
The inside does not have sealing ring, product at the time of molding, can be a problem that the place of inserts cavity generates flash, overlap, to understand
Certainly this problem, our company use high-temperature-resistant flexible sealing structure, and principle is put in the cavity that die joint and inserts coordinate
Set flexible seal ring, common type has semi-circular shape, circular ring shape, half elliptic, ellipse, half square, rectangular, half abnormity, different
The multiple structural forms such as shape；Flexible seal ring is embedded into the groove of cavity, apertured position seals in cavity are got up,
Silicon rubber is prevented to penetrate into gap before curing, flexible sealing structure had both solved the problems such as product surface flash, overlap,
Keep product surface more beautiful；Meanwhile mould structure is simple, shaping efficiency is high, can produce in enormous quantities, good product quality, cost
It is low.
The present invention uses overflow groove structure simultaneously, and principle is to open one small excessive glue mouth, then on cavity glue-feeder opposite
An overflow storage glue groove is opened beside overflow port, when silicon rubber is injected into cavity, air extra in cavity is compressed to excessive
In glue groove, it in this way, the product in cavity is before curing, can be filled up completely full, air pocket, bubble, starved are not had in product
The problems such as, after the completion of molding, then the trimmed away product overflow out.The exhaust excessive glue structure that the present invention uses, is used for
The problems such as exhaust and excessive glue when molding, solution is vented the bubble, air pocket, starved of bad appearance；Product quality is stablized, can be with standard
Metaplasia is produced, and processing cost is low, and production efficiency is high.
Due to the application of the above technical scheme, the present invention has following advantages compared with prior art：
Overflow-type injection mold of the present invention solves the problems such as product surface flash, overlap, also product surface is made more to float
It is bright；Meanwhile solving the problems such as bubble, air pocket, starved for being vented bad appearance；The configuration of the present invention is simple, good product quality and
Stablize, can be produced with standard batch, processing cost is low, and production efficiency is high.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand present disclosure and be implemented, and it is not intended to limit the scope of the present invention, all according to the present invention
Equivalent change or modification made by Spirit Essence should all cover within the scope of the present invention.
