Abstract

The utility model discloses the hot mouth core of the double-canopy closure system of a kind of compound, comprise hot mouth main body and conduction copper core; Described hot mouth body interior and conduction copper core inner are equipped with runner; Described conduction copper core is arranged on hot mouth body interior, and hot mouth main body is stretched out in one end; Described hot mouth main body adopts main body sealing to be sealed by conduction copper core; The utility model is by being arranged on hot mouth body interior by conduction copper core, hot mouth main body is stretched out in one end, hot mouth main body adopts main body sealing to be sealed by conduction copper core, so in use, conduction copper core does not directly contact with die, and thermal loss is few, it is very long that conduction copper core can do, make mold cavity more existing less, improve the intensity of mould, ensure the quality of technique.

Description

The hot mouth core of a kind of double-canopy closure system of compound

Technical field

The utility model relates to the hot mouth core of the double-canopy closure system of a kind of compound, belongs to Hot runner Technology field.

Background technology

In injection mold, often use hot mouth, hot mouth conventional in prior art, comprise hot mouth main body, copper fuse, fuse fixed cap, fuse steel bushing, described copper fuse is arranged in hot mouth main body, is provided with fuse steel bushing between described copper fuse and hot mouth main body; Described copper fuse is fixed by fuse fixed cap with the part of stretching out hot mouth main body, and the copper fuse of old structure is very short, and can not be used in the dark system of die complexity, the degree of depth, this structure mold Jiao Kou place intensity is bad, very thin, the easy craze and transfiguration of die.

Utility model content

For the technical problem of above-mentioned existence, the purpose of this utility model is: propose the hot mouth core of the double-canopy closure system of compound that a kind of thermal loss is few, mold cavity is little, mould strength is good.

Technical solution of the present utility model is achieved in that the hot mouth core of the double-canopy closure system of a kind of compound, comprises hot mouth main body and conduction copper core; Described hot mouth body interior and conduction copper core inner are equipped with runner; Described conduction copper core is arranged on hot mouth body interior, and hot mouth main body is stretched out in one end; Described hot mouth main body adopts main body sealing to be sealed by conduction copper core.

Preferably, described conduction copper core stretch out that the length of hot mouth main body is conduction copper core overall length 1/2nd.

Preferably, the discharge end of described conduction copper core is provided with three equally distributed plastic holes.

Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:

The hot mouth core of the double-canopy closure system of a kind of compound of the present utility model, by conduction copper core is arranged on hot mouth body interior, hot mouth main body is stretched out in one end, and hot mouth main body adopts main body sealing to be sealed by conduction copper core, so in use, conduction copper core does not directly contact with die, thermal loss is few, and it is very long that conduction copper core can do, and the mold cavity made is more existing less, the intensity of the mould improved, ensures the quality of technique.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:

Accompanying drawing 1 is the structural representation of the hot mouth core of the double-canopy closure system of a kind of compound of the present utility model;

Wherein: 1, hot mouth main body; 2, conduction copper core; 3, runner; 4, plastic hole.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described.

Be the hot mouth core of the double-canopy closure system of a kind of compound described in the utility model as shown in Figure 1, comprise hot mouth main body 1 and conduction copper core 2; Described hot mouth main body 1 inside and conduction copper core 2 inside are equipped with runner 3; It is inner that described conduction copper core 2 is arranged on hot mouth main body 1, and hot mouth main body 1 is stretched out in one end; Described hot mouth main body 1 adopts main body sealing to be sealed by conduction copper core 2; The length that described conduction copper core 2 stretches out hot mouth main body 1 is 1/2nd of conduction copper core 2 overall length; The discharge end of described conduction copper core 2 is provided with three equally distributed plastic holes 4.

During use, inner by conduction copper core 2 being arranged on hot mouth main body 1, hot mouth main body 1 is stretched out in one end, and hot mouth main body 1 adopts main body sealing to be sealed by conduction copper core 2, so in use, conduction copper core 2 does not directly contact with die, thermal loss is few, and it is very long that conduction copper core 2 can do, and makes mold cavity more existing less, improve the intensity of mould, ensure the quality of technique.

The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
