The novel injection molding hot nozzle provided by the utility model is inventive and reasonable in structure design; the nozzle head covers the head part of the nozzle core, and the glue outlet is arranged; not only can the phenomena of materials stems, wiredrawing and easiness in glue breaking be reduced effectively, but also the thermal loss of the nozzle core is reduced effectively so as to guarantee that glue materials on the nozzle core are difficult to cool down; the glue material blocking phenomenon is prevented; the normal operation of the hot nozzle is ensured; the operation stability is improved greatly; further the injection molding efficiency is improved; in addition, the novel injection molding hot nozzle provided by the utility model is simple in integral structure, is easy to achieve, is low in cost, and is beneficial to wide popularization and application.
Description
Technical field
The utility model relates to injection heat and chews technical field, is specifically related to a kind of Novel injection molding heat and chews.
Background technology
In the moulding of Chinese market plastic cement products, injection moulding has occupied extremely important position at present, and injection moulding mainly is divided into cold runner and hot flow path, and injection heat is chewed mainly and is used on hot flow path.
The injection heat of selling is on the market chewed varied, and it has different design concepts separately, makes every effort to reach the instructions for use of different user.Although but these injection heats chew and can roughly satisfy instructions for use, design all not very ingeniously, cause its material handle longer, and wire drawing, disconnected glue phenomenon easily appear, be difficult to guarantee the quality of injecting products, in addition, the sizing material of chewing on core is easily cooling, clogging very easily occurs, is unfavorable for producing.
The utility model content
The purpose of this utility model is, for above-mentioned deficiency, provides a kind of structural design ingenious, reasonable, effectively reduces the Novel injection molding heat of material handle, wire drawing and the glue phenomenon of easily breaking and chews.
For achieving the above object, technical scheme provided by the utility model is: a kind of Novel injection molding heat is chewed, it comprises chews body, chews head and chew core, described chewing is provided with an axial passage with it, the head end of this axial passage is provided with successively the first assembling position and second by interior extremely outer order and assembles the position, the described core of chewing is arranged in the first assembling position, and head slightly stretches out described axial passage, the described head of chewing is arranged on described the second assembling position, and the described head of chewing core is covered, and be provided with gum outlet at this front end of chewing head.
As a kind of improvement of the present utility model, the tail end of described axial passage dwindles gradually and forms a choke.
As a kind of improvement of the present utility model, the described in-core of chewing is provided with one and is used for the sizing material passage that is connected with described axial passage, this sizing material passage is consistent with the pipe diameter size of described axial passage, and the head end of this sizing material passage dwindles gradually and forms an injection molding mouth that is connected with described gum outlet.
As a kind of improvement of the present utility model, the caliber of the end that described gum outlet is connected with described injection molding mouth is less, and the other end is and increases gradually shape.
As a kind of improvement of the present utility model, the described afterbody of chewing body is provided with deck, and the head end lateral wall is provided with screens.
The beneficial effects of the utility model are: the utility model structural design is ingenious, reasonable, chewing the head that will chew core covers, and be provided with gum outlet, not only effectively reduce material handle, wire drawing and the glue phenomenon of easily breaking, chew the core heat loss but also effectively reduced, the sizing material that assurance is chewed on core is difficult for being cooled, avoid occurring the sizing material clogging, guarantee the normal operation that heat is chewed, greatly improve the stability of work, and then improve injection moulding efficient, overall structure of the present utility model is simple in addition, be easy to realize, cost is low, is beneficial to wide popularization and application.
Below in conjunction with accompanying drawing and embodiment, the utility model is further illustrated.

The specific embodiment
Embodiment, referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of Novel injection molding heat that the present embodiment provides is chewed, it comprises chews body 1, chews 2 and chew core 3, the described body 1 of chewing is provided with an axial passage 11, the head end of this axial passage 11 is provided with the 12 and second assembling position 13, the first assembling position by interior successively to outer order, the described core 3 of chewing is arranged in the first assembling position 12, and head slightly stretches out described axial passage 11, describedly chew 2 and be arranged on described the second assembling position 13, and the described head of chewing core 3 is covered, and be provided with gum outlet 21 at this front end of chewing 2.
The tail end of described axial passage 11 dwindles gradually and forms a choke 14.
Described chewing is provided with one and is used for the sizing material passage 31 that is connected with described axial passage 11 in core 3, this sizing material passage 31 is consistent with the pipe diameter size of described axial passage 11, and the head end of this sizing material passage 31 dwindles gradually and forms an injection molding mouth 32 that is connected with described gum outlet 21.
Described gum outlet 21 is less with the caliber of the end that described injection molding mouth 32 is connected, and the other end is and increases gradually shape.Effectively reduce injection pressure and increase the injection moulding flow, and then improve injection moulding efficient.
The described afterbody of chewing body 1 is provided with deck 15, and the head end lateral wall is provided with screens 16.Facilitate installation and removal.
