Abstract
The invention discloses an injection nozzle which includes a nozzle body, an empty cavity arranged in the middle part of the nozzle body and communicated with the outside of the nozzle body, a thread arranged on the lower surface of the nozzle body and at least two nozzles uniformly arranged at the upper end of the nozzle body; discharge channels are respectively arranged between the nozzles and the empty cavity. The invention is characterized in that the discharge channels are respectively arranged at one side of the axle wire of the nozzle body and form a certain incline degree with the axle wire; the direction of the incline degree of the discharge channels is the same as the rotation direction of the thread. The injection nozzle has the advantages that when the injection nozzle is in a working state, the counterforce of material leads the injection nozzle to screw according to the rotation direction of the thread; thereby achieving the function of self-locking and avoiding a die from being damaged caused by the loosening of the injection nozzle.
Description
Technical field
The present invention relates to a kind of injection made showerhead, relate in particular to a kind of injection made showerhead that has auto-lock function.
Background technology
Strict standard is being arranged aspect the curable product production, and the material of mould and the requirement of precision are very strict.At present, the lower surface of the matching used shower nozzle of injection machine is provided with screw thread, and it can be screwed with the screw thread on the patrix, and nozzle cooperates with counterdie.In injection moulding process, material has certain speed during from the ejection of the discharging opening of shower nozzle, simultaneously frequent production product, this just makes shower nozzle be subjected to the step reaction force that material is given, and this active force makes that shower nozzle is easily loosening even come off, yet, all cooperate between mould and the shower nozzle up and down according to certain requirement, loosening shower nozzle will destroy this cooperation, and serious words even meeting mold damage cause scrapping of a whole set of mould.
Summary of the invention
The object of the present invention is to provide a kind of injection made showerhead that has auto-lock function.
Further purpose of the present invention is to provide a kind of injection made showerhead of skidding of preventing when manual rotation injection made showerhead.
For realizing purpose of the present invention, a kind of injection made showerhead, comprise head body, be arranged on head body middle part and with the cavity of head body exterior, be arranged on the screw thread of head body lower surface, and be arranged on head body upper end evenly be provided with at least two nozzles, between nozzle and cavity, be respectively arranged with tapping channel, described tapping channel is separately positioned on axis one side of head body, and become certain angle of inclination with the axis, the direction at the angle of inclination of tapping channel is identical with the thread rotary orientation direction.When injection made showerhead adopted right-handed thread, tapping channel became certain angle of inclination with the axis, and direction takes over.Otherwise when injection made showerhead adopted left hand thread, tapping channel became certain angle of inclination with the axis, and direction is taken back.
For realizing further goal of the invention of the present invention, a kind of injection made showerhead also comprises: the upper surface of head body is roughness.
Advantage of the present invention is: tapping channel becomes certain angle of inclination with the axis, and the direction at the angle of inclination of tapping channel is identical with the thread rotary orientation direction, adopt such method after, make shower nozzle reach the function of self-locking, thereby prevented the loosening of shower nozzle.

The specific embodiment
Shown in Fig. 1,2,3, a kind of injection made showerhead, comprise head body 3, be arranged on head body 3 middle parts and with the cavity 2 of head body 3 exterior, be arranged on the screw thread 4 of head body 3 lower surfaces, and be arranged on head body 3 upper ends evenly be provided with at least two nozzles 1, between nozzle 1 and cavity 2, be respectively arranged with tapping channel 11, described tapping channel 11 is separately positioned on axis one side of head body 3, and become certain angle of inclination with the axis, the direction at the angle of inclination of tapping channel 11 is identical with screw thread 4 rotation direction directions.If when injection made showerhead adopted right-handed thread, tapping channel became certain angle of inclination with the axis, and direction takes over.Otherwise when adopting left hand thread as if injection made showerhead, tapping channel becomes certain angle of inclination with the axis, and direction is taken back.
The upper surface of described injection made showerhead body 3 is roughness.
Claims (2)
1, a kind of injection made showerhead, comprise head body (3), be arranged on head body (3) middle part and with the cavity (2) of head body (3) exterior, be arranged on the screw thread (4) of head body (3) lower surface, and be arranged on head body (3) upper end evenly be provided with at least two nozzles (1), between nozzle (1) and cavity (2), be respectively arranged with tapping channel (11), it is characterized in that: described tapping channel (11) is separately positioned on axis one side of head body (3), and become certain angle of inclination with the axis, the direction at the angle of inclination of tapping channel (11) is identical with screw thread (4) rotation direction direction.
2, according to the described injection made showerhead of claim 1, it is characterized in that: the upper surface of head body (3) is roughness.
