Abstract
The utility model relates to the technical field of nozzles, and particularly relates to a nozzle with flow-limiting and leak-proof functions, which is applied to a hot runner of an injection die. The nozzle comprises a nozzle head (1) and a nozzle body (2) which are in thread connection with each other, and is characterized in that an overflow lock (3) is inserted and sleeved inside the nozzle body (2), a through-hole (31) is molded on the overflow lock (3), a circular conical surface (32) is molded at the front part of the overflow lock (3), and the circular conical surface (32) is butted against the opening at the upper part of a nozzle hole (11) on the nozzle head (1). The utility model can prevent the overflow of colloidal substances from the nozzle and the leakage of colloidal substances from the threads, and can adjust the flow capacity of the nozzle.
Description
Technical field:
The utility model relates to the nozzle technology field, more specifically to a kind of can limited flow size and nozzle that can leakproof glue.
Background technology:
Existing spray glue nozzle is made of the nozzle head that is spirally connected on the nozzle body, and its weak point is: when 1, the spray orifice on the nozzle head is big, be easy to generate flash curtain coating phenomenon, promptly the colloid in the nozzle flows out from spray orifice automatically.2, because nozzle body and nozzle head are screwed onto together, colloid easily overflows from screw thread.3, the flow-control of nozzle generally is by flowmeter control, and nozzle itself does not possess flow control function, and this is because under constant pressure, the spray orifice size on the nozzle head is that constant reason causes.
The utility model content:
The purpose of this utility model is exactly the deficiency at prior art, but and a kind of current limliting leakproof nozzle is provided, it can prevent the colloid flash curtain coating in the nozzle and overflow the flow size that can regulate nozzle simultaneously from screw thread.
Technology solution of the present utility model is as follows:
But the injection mold hot-runner nozzle of current limliting leakproof, comprise the nozzle head and the nozzle body that are screwed onto together, be inserted with the overflow lock in nozzle body, overflow is locked and is formed through hole, the front portion of overflow lock forms taper seat, and this taper seat resists the spray orifice upper opening place on nozzle head.
Diameter 0.02～the 0.1mm of the external diameter of portion's cylinder less than nozzle body locked in described overflow.
The beneficial effects of the utility model are:
1, when the aperture of spray orifice was big, the aperture of the through hole of overflow lock was littler than spray orifice, can prevent to produce flash curtain coating phenomenon like this.
2, the diameter 0.02～0.1mm of the external diameter of portion's cylinder less than nozzle body locked in overflow.Advanced to prevent behind the colloid condense in space between overflow lock and the nozzle body that colloid from spilling from the screw thread that nozzle body and nozzle head are spirally connected.
3, the overflow lock is that sleeve can take out replacing in nozzle body, and when needing the control flow, the overflow lock of changing different apertures through hole just can be controlled the flow of nozzle.
Description of drawings:
Fig. 1 is a perspective exploded view of the present utility model
The specific embodiment:
Embodiment: see shown in Figure 1, but current limliting leakproof nozzle, comprise the nozzle head 1 and the nozzle body 2 that are screwed onto together, in nozzle body 2, be inserted with overflow lock 3, form through hole 31 on the overflow lock 3, the front portion of overflow lock 3 forms taper seat 32, the spray orifice 11 upper opening places that this taper seat 32 resists on nozzle head 1.
Diameter 0.02～the 0.1mm of the external diameter of 3 top cylinders 33 less than nozzle body 2 locked in described overflow.
Operation principle: when the aperture of spray orifice 11 was big, the aperture of the through hole 31 of overflow lock 3 was littler than spray orifice 11, can prevent to produce flash curtain coating phenomenon like this.
Diameter 0.02～the 0.1mm of the external diameter of 3 top cylinders 33 less than nozzle body 2 locked in overflow.Advanced to prevent behind the colloid condense in space between overflow lock 3 and the nozzle body 2 that colloid from spilling from the screw thread that nozzle body 2 and nozzle head 1 are spirally connected.
Claims (2)
1. but the injection mold hot-runner nozzle of current limliting leakproof, comprise the nozzle head (1) and the nozzle body (2) that are screwed onto together, it is characterized in that: in nozzle body (2), be inserted with overflow lock (3), form through hole (31) on the overflow lock (3), the front portion of overflow lock (3) forms taper seat (32), and this taper seat (32) resists spray orifice (11) the upper opening place on nozzle head (1).
2. but the injection mold hot-runner nozzle of current limliting leakproof according to claim 1 is characterized in that: the external diameter of overflow lock (3) top cylinder (33) is less than the diameter 0.02～0.1mm of nozzle body (2).
