Abstract
The invention discloses a glue sealing valve needle. The glue sealing valve needle comprises a valve needle main body and a valve needle head, wherein the valve needle head is matched with a mold glue opening, and comprises a conical section and a straight section arranged at the top end of the conical section; the mold glue opening comprises a conical groove and a cylindrical through hole; the axle line of the cylindrical through hole and the axle line of the conical groove are arranged on the same straight line; and the cylindrical through hole is communicated with the conical groove. According to the utility model, the glue sealing valve needle can form two sections of sealed glue, so that the glue sealing effect is good; and when the valve needle is impacted, a mold is not easy to deform, and the condition that the glue is not sealed can be prevented.
Description
Technical field
The present invention relates to die workpiece field, particularly relate to a kind of sealing needle.
Background technology
Old structure needle only has one section of gradient sealing, and with the Jiao Kou position insufficient strength of mould cooperation place, mold glue mouth place is wedge angle, and easily by needle blastic deformation, product runs burr.Needle only has a gradient, and the length accuracy that requirement coordinates with mould requires high, and in short-term, envelope is glue incessantly for length, when length is long, easily breaks mold glue mouth-shaped.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of sealing needle, can form two sections of sealings, sealing is effective, at mold glue mouth place, there is a small straight section, when needle impacts, mould is not easy distortion, simultaneously, high when to needle length direction, required precision does not have one section of gradient sealing, be not easy to occur the incessantly situation of glue of envelope.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of sealing needle is provided, comprises needle body and needle head, needle head coordinates with mold glue mouth, and described needle head comprises conical section and is located at the straight section on conical section top; Described mold glue mouth comprises conical socket and cylindrical hole, and the axis of cylindrical hole and conical socket is on same straight line, and cylindrical hole is communicated with conical socket.
Preferably, the diameter of the straight section of the cylindrical hole of described mold glue mouth and needle head matches, and cylindrical hole length is less than the length of straight section; The cone angle of described mold glue prostomum connected in star is greater than the cone angle of described needle head conical section.
The invention has the beneficial effects as follows: the present invention can form two sections of sealings, and sealing is effective.
Accompanying drawing explanation
Fig. 1 is the structural representation of the sealing needle of prior art;
Fig. 2 is the structural representation of a kind of sealing needle of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, needle head; 2, mold glue mouth; 3, conical section; 4, straight section.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to Fig. 1 and Fig. 2, the embodiment of the present invention comprises:
A sealing needle, comprises needle body and needle head 1, and needle head 1 coordinates with mold glue mouth 2, and described needle head 1 comprises conical section 3 and is located at the straight section 4 on conical section 3 tops; Described mold glue mouth 2 comprises conical socket and cylindrical hole, the axis of cylindrical hole and conical socket is on same straight line, and cylindrical hole is communicated with conical socket, during sealing, glue forms a straight section and two sections of sealings of a conical section in glue mouth, between two sections of sealings, have angle, sealing is effective; The diameter of the straight section 4 of the cylindrical hole of described mold glue mouth 2 and needle head 1 matches, and cylindrical hole length is less than the length of straight section 4; The cone angle of described mold glue mouth 2 conical sockets is greater than the cone angle of described needle head conical section 3, and needle head 1 can insert in mold glue mouth 2 fast and accurately.The present invention can form two sections of sealings, and sealing is effective, at mold glue mouth place, has a small straight section, and when needle impacts, mould is not easy distortion, meanwhile, high when to needle length direction, required precision does not have one section of gradient sealing, is not easy to occur the incessantly situation of glue of envelope.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention and accompanying drawing content to do; 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 invention.
Claims (2)
1. a sealing needle, comprises needle body and needle head, and needle head coordinates with mold glue mouth, it is characterized in that: described needle head comprises conical section and is located at the straight section on conical section top; Described mold glue mouth comprises conical socket and cylindrical hole, and the axis of cylindrical hole and conical socket is on same straight line, and cylindrical hole is communicated with conical socket.
2. a kind of sealing needle according to claim 1, is characterized in that, the diameter of the straight section of the cylindrical hole of described mold glue mouth and needle head matches, and cylindrical hole length is less than the length of straight section; The cone angle of described mold glue prostomum connected in star is greater than the cone angle of described needle head conical section.
