Technical field
The utility model relates to injection molding technical field, especially a kind of hot mouth preventing plastic cement wire drawing.
Background technology
After the hot mouth injection sizing material of injection machine, through refrigerating work procedure, product can solidify, but connects with machine barrel nozzle due to its front end, thus remains certain temperature, and therefore the sizing material of hot mouth mouth does not solidify completely sometimes.If now open mould, the material that spinnability (can be extended into thread during stretching and can not disconnect) is good is just easy produces wire drawing in sprue front end.From condition of molding, if resin temperature (particularly nozzle temperature) or mold temperature higher, then easily cause wire drawing.
Utility model content
The utility model aims to provide one and fundamentally solves wire drawing phenomenon, enhances productivity, the hot mouth preventing plastic cement wire drawing be worth promoting.
For achieving the above object, the utility model provides following technical scheme: a kind of hot mouth preventing plastic cement wire drawing, comprise heating collar, hot mouth body, mouth and cut off machine, a shaft orientation flowing channel is provided with in described hot mouth body, the front end of this shaft orientation flowing channel is provided with the assembling recess matched with mouth, and mouth is arranged in the assembling recess of shaft orientation flowing channel front end; The rear portion of described mouth is provided with passage flow duct always, and this straight-through runner is communicated with shaft orientation flowing channel, and the front portion of mouth is provided with a tapered runner, and the connectivity part of tapered runner and straight-through runner is provided with cut off machine, and the rear end import of tapered runner is divided into two parts by this cut off machine; Described heating collar is enclosed within hot mouth body, and this heating collar outside is provided with protective sleeve, and the rear end of this hot mouth body is provided with the draw-in groove coordinated with heating collar, protective sleeve, and the outside of draw-in groove is provided with the alignment pin coordinated with protective sleeve.
As further scheme of the present utility model: described mouth is provided with external screw thread, in assembling recess, be provided with the internal thread coordinated with mouth.
As further scheme of the present utility model: the front end of described protective sleeve is fixed by jump ring and hot mouth body.
As further scheme of the present utility model: the cross section of described tapered runner is tapered.
As further scheme of the present utility model: the cross section of described cut off machine is trapezoidal.
Compared with prior art, the beneficial effects of the utility model are: this prevents the rear end import department of the mouth tapered runner of the hot mouth of plastic cement wire drawing to be provided with cut off machine, the rear end import of tapered runner is divided into two parts by this cut off machine, change the flow direction of fluid and reduce the speed of fluid, thus the stress of fluidity of inflow tapered runner is reduced, thus effectively prevent from causing because rate of flow of fluid is too fast occurring wire drawing phenomenon, fundamentally solve wire drawing phenomenon, enhance productivity, be worth promoting.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-8, in the utility model embodiment, a kind of hot mouth preventing plastic cement wire drawing, comprise heating collar 1, hot mouth body 2, mouth 5 and cut off machine 7, be provided with a shaft orientation flowing channel 201 in described hot mouth body 2, the front end of this shaft orientation flowing channel 201 is provided with the assembling recess 202 matched with mouth 5, and mouth 5 is arranged in the assembling recess 202 of shaft orientation flowing channel 201 front end, mouth 5 is provided with external screw thread, is provided with the internal thread coordinated with mouth 5 in assembling recess 202, the rear portion of described mouth 5 is provided with passage flow duct 501 always, this straight-through runner 501 is communicated with shaft orientation flowing channel 201, the front portion of mouth 5 is provided with a tapered runner 502, the cross section of tapered runner 502 is tapered, this tapered runner 502 is provided with cut off machine 7 with the connectivity part of straight-through runner 501, the rear end import of tapered runner 502 is divided into two parts by this cut off machine 7, change the flow direction of fluid and reduce the speed of fluid, thus the stress of fluidity of inflow tapered runner 502 is reduced, thus effectively prevent from causing because rate of flow of fluid is too fast occurring wire drawing phenomenon, the cross section of this cut off machine 7 is trapezoidal, described heating collar 1 is enclosed within hot mouth body 2, this heating collar 1 outside is provided with protective sleeve 4, the front end of protective sleeve 4 is fixed by jump ring 6 and hot mouth body 2, and the rear end of this hot mouth body 2 is provided with the draw-in groove coordinated with heating collar 1, protective sleeve 4, and the outside of draw-in groove is provided with the alignment pin 3 coordinated with protective sleeve 4.
Design feature of the present utility model:
