Description
Technical field
This utility model relates to hot runner mould technical field, particularly relate to a kind of simple in construction, can effective preventing from cementing leakage
Hot flow path glue-leakage-resistant sheath.
Background technology
Hot flow path (hot runner) uses in injection mold, and the plastic pellet of thawing is injected into the type of mould
Heating component system in chamber.Hot runner mould is that with runner, the running channel of traditional type mould or shree plates mold is passed through heating,
Need not take out runner and the brand-new structure of one of running channel when each shaping.Enter to water in hot flow path mode and will can make mould
Simple structure, shape easily, and can accelerate forming speed, reduce stub bar when shaping, economize in raw materials cost.
From the sixties in last century, hot flow path starts to apply to injection mold, and China once set up special in the eighties
The institute of hot flow path, yet with various reasons not success.Enter this century, along with the fast development of die industry, heat
Runner industry have also been obtained quickly development.In recent years due to the quick growth of cost of labor, and the raising of automaticity
Requirement, hot flow path industry presents scene of flourishing life.
Owing to hot flow path is compared with common flow passage, having the advantage of uniqueness, therefore hot flow path is extensive in injection mold
Application.But our country is relatively backward relative to developed country or technical equipment, mould machining accuracy is not enough, thus causes
Hot runner mould in use leaks glue phenomenon and frequently occurs, and causes hot flow path electric heating system to go wrong, many clients because of
Leakage glue problem use after overheated runner mold not in use by, even the hot flow path in hot runner mould is removed, changes back common
Runner.Have a strong impact on hot flow path in the popularization of China and to be widely used.
Therefore, current die industry needs a kind of device effectively preventing hot flow path leakage glue, to promote pushing away of hot flow path
Wide application.
Summary of the invention
This utility model is for above-mentioned the deficiencies in the prior art, it is provided that a kind of hot flow path glue-leakage-resistant sheath, its structure letter
Single, can the appearance of effective preventing from cementing leakage phenomenon.
For solving problems of the prior art, the concrete technical scheme that this utility model uses is:
A kind of hot flow path glue-leakage-resistant sheath, it is the barrel-shaped sheath of a hollow, the bottom of described barrel-shaped sheath be provided with for
Installing the hot mouth installing hole of hot mouth, the periphery of described barrel-shaped sheath is provided with annular protrusion, and described annular protrusion includes installation circle
Cambered surface installs the sealing surface of arc surface side with being located at, and described hot flow path glue-leakage-resistant sheath is by described installation arc surface and mould
Tool body fits is arranged.
Preferably scheme, the cross section of described annular protrusion is isosceles trapezoid, rectangle or irregular quadrilateral.
Further preferred scheme, the length of described installation arc surface is not less than 3mm.
Further preferably scheme, is provided with between internal diameter and the external diameter of Hot nozzle body of described hot mouth installation through hole and coordinates
Sealing face.
By using such scheme, a kind of hot flow path glue-leakage-resistant sheath of the present utility model compared with prior art, its skill
Art effect is:
1, the face that coordinates of this utility model hot flow path glue-leakage-resistant sheath and mould is provided with trapezoidal protruding ring, isosceles trapezoid,
The glue that the side in rectangle or irregular quadrilateral cross section can effectively prevent hot mouth from spraying spills, and is favorably improved injection effect,
Save production cost；
3, the length installing arc surface is not less than 3mm, and the glue sprayed from hot mouth can be played the effect that second time seals by it,
Dual-seal, sealing effectiveness is more preferable；
4, this utility model directly changes the common sheath outside hot mouth into glue-leakage-resistant sheath, it is not necessary to carry out numerous and diverse to hot mouth
Processing, glue-leakage-resistant jacket structure is simple, and cost of manufacture is low；
5, after using this utility model, hot mouth front portion the plastic cement escaped out is by sheath and mouth body, between sheath and mould
Twice coordinate face to be enclosed in a limited region, will not be excessive and affect the normal use of mould.

Fig. 1 is the mounting structure schematic diagram of this utility model a kind of hot flow path glue-leakage-resistant sheath；
Fig. 2 is the overall structure schematic diagram of this utility model a kind of hot flow path glue-leakage-resistant sheath；
Fig. 3 is the A portion enlarged drawing in the overall structure schematic diagram of this utility model a kind of hot flow path glue-leakage-resistant sheath.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage of greater clarity, below in conjunction with instantiation and join
According to accompanying drawing, this utility model is further described.It should be understood that these describe the most exemplary, and it is not intended to limit
Scope of the present utility model.Additionally, in the following description, eliminate the description to known features and technology, unnecessary to avoid
Concept of the present utility model is obscured on ground.
As it is shown in figure 1, this utility model hot flow path glue-leakage-resistant sheath 1 directly replaces conventional common sheath, runner is prevented
Leakage plastic boot 1 is installed between hot mouth 2 and die ontology 3, and the glue 4 escaped out is enclosed in glue-leakage-resistant sheath 1, hot mouth 2 and mould
Between body 3.
As shown in Figures 2 and 3, this utility model a kind of hot flow path glue-leakage-resistant sheath is the barrel-shaped sheath of a hollow, described
The bottom of barrel-shaped sheath is provided with the hot mouth for installing hot mouth and installs through hole 5, and described hot mouth installs internal diameter and the Hot nozzle of through hole 5
