Abstract
The invention discloses a pilot-operated type valve needle glue sealing system. The system comprises a valve needle, a core and a core cover. The core is arranged in the core cover. The valve needle is arranged in the core. A first step at the head of the valve needle is in a clearance fit relationship with a round glue gate of the core cover. The single edge of the fit gap has the size of 0.002-0.005mm. A second step of the valve needle is in a clearance fit relationship with a second step of the core cover and the single edge of the fit gap has the size of 0.01-0.02mm. A third step of the valve needle is in a clearance fit relationship with the core and the single edge of the fit gap has the size of 0.1-0.2mm. Through the pilot-operated type valve needle glue sealing system, stress points of the head of the valve needle and the round glue gate are uniform, the round glue gate is not changed into an elliptical structure, the valve needle and the round glue gate resist wear and have long service lives, the product glue gate is complete and burr or aberration around the glue gate is not produced.
Description
Technical field
The present invention relates to a kind of improvement of needle sealing system, particularly a kind of needle head and circular glue mouth stress point even, glue mouth can not become oval, needle and circular glue mouth wear-resistant, life-span is long, and product glue mouth is complete, can not the jagged or pilot-operated type needle sealing system of aberration around Jiao Kou.
Background technology
Existing needle is with when heating fuse to prevent from directly coordinating, the high heat of fuse is transmitted to needle, make the temperature drift of needle head, there are aberration or sun print in product Jiao Kou position, needle does not closely cooperate with fuse, the monolateral gap leaving 0.1 ~ 0.5 millimeter, because TOP-TIP is in the duty of heating, hot mouth and runner plate can be out of shape, when needle dangles in hot mouth, meeting secundly, needle is travelling forward in sealing process, the side of needle head first can contact with the side of fuse lid Jiao Kou, cause the stress point of circular Jiao Kou inconsistent, Jiao Kou can under repeatedly unbalanced stressed shock, become oval Jiao Kou, like this, needle is envelope incessantly glue just, jagged on product Jiao Kou.Product is defective, glue mouth must again repair circular after could normal produce.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of needle head and circular glue mouth stress point is even, glue mouth can not become oval, needle and circular glue mouth wear-resistant, the life-span is long, and product glue mouth is complete, can not the jagged or pilot-operated type needle sealing system of aberration around Jiao Kou.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is a kind of pilot-operated type needle sealing system, comprising: needle, fuse and fuse lid; It is inner that described fuse is arranged on fuse lid, and described needle is arranged on fuse inside; Described needle head first step and core cap circular glue mouth matched in clearance, fit clearance is monolateral is 0.002 to 0.005 millimeter; The second step of described needle and the second step matched in clearance of fuse lid, fit clearance is monolateral is 0.01 to 0.02 millimeter; 3rd step of described needle and fuse matched in clearance, fit clearance is monolateral is 0.1 to 0.2 millimeter.
The invention has the beneficial effects as follows: a kind of pilot-operated type needle sealing system of the present invention, needle head and circular glue mouth stress point are even, and glue mouth can not become oval, needle and circular glue mouth wear-resistant, the life-span is long.Product glue mouth is complete, can not jagged or aberration around Jiao Kou.

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1 to Fig. 3, the embodiment of the present invention comprises:
A kind of pilot-operated type needle sealing system, comprising: needle 1, fuse 2 and fuse lid 3; It is inner that described fuse 2 is arranged on fuse lid 3, and it is inner that described needle 1 is arranged on fuse 2; Described needle 1 head first step 4 and fuse lid 3 circular glue mouth matched in clearance, fit clearance is monolateral is 0.002 to 0.005 millimeter; The second step 5 of described needle 1 and the second step matched in clearance of fuse lid 3, fit clearance is monolateral is 0.01 to 0.02 millimeter; 3rd step 6 of described needle 1 and fuse 2 matched in clearance, fit clearance is monolateral is 0.1 to 0.2 millimeter.
During use, needle has three steps and fuse, fuse lid does matched in clearance, when the 3rd step 6 of needle is when coordinating with fuse 2, can the beat of needle 1 be controlled in the scope of 0.2 ~ 0.4, now the second step 5 of needle and first step 4 also coordinate with fuse lid 3, when the second step 5 of needle 1 moves to second step of fuse lid 3, can the beat of needle 1 be controlled in the scope of 0.02 ~ 0.04, now needle 1 first step 4 does not also coordinate with the Jiao Kou of fuse lid 3, and the center of the Jiao Kou of the center of needle 1 and fuse lid 3 almost on the same line, when needle 1 head first step 4 move to coordinate with the Jiao Kou of fuse lid 3 time, completely concentric.
The invention has the beneficial effects as follows: of the present invention a kind of pilot-operated type needle sealing system, needle head and circular glue mouth stress point are even, and glue mouth can not become oval, needle and circular glue mouth wear-resistant, the life-span is long.Product glue mouth is complete, can not jagged or aberration around Jiao Kou.
Below be only embody rule example of the present invention, protection scope of the present invention is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within rights protection scope of the present invention.
