Abstract
The utility model discloses a hot nozzle valve needle sleeve which comprises a sleeve body, wherein the middle part of the sleeve body is radially bulged to form a positioning boss, the lower part of the sleeve body is radially sunk to form a concave position, and a radial through hole communicated with the inner hole of the sleeve body is formed in the concave position. The hot nozzle valve needle sleeve has a smart and reasonable structural design and is additionally provided with the concave position and the radial through hole, a valve needle is effectively prevented from being clamped when glass fibers exist in materials, the normal work of a nozzle is ensured, and the phenomenon that sizing materials block the injection nozzle due to needle clamping is also effectively avoided. The stability is high, and the working efficiency is increased. Moreover, the positioning boss is arranged, the disassembly and assembly process is greatly simplified, the daily maintenance is convenient, and the time and the labor are saved. In addition, the hot nozzle valve needle sleeve has the advantages of simple and compact integral structure, easiness in realization and low cost and is beneficial to wide promotion and application.
Description
Technical field
The utility model relates to injection heat and chews technical field, is specifically related to a kind of heat of injection heat in chewing that is applied in and chews valve needle cover.
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 moulding is penetrated to chew mainly and is used on hot flow path.
The injection moulding of selling is on the market penetrated and is chewed variedly, and it has different design concepts separately, makes every effort to reach the instructions for use of different user.Although but these injection mouldings are penetrated to chew and can roughly be satisfied instructions for use, but design all not very ingeniously, due to the needle longer dimension, all need be provided with valve needle cover needle is led and spacing for this reason, avoiding occurring dancing, and stop to cause needle to fracture or leak the glue phenomenon; Yet existing valve needle cover needle card pin phenomenon easily occurs when material has glass, not only is difficult to guarantee to mould to penetrate product quality, also affects the equipment normal operation, 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, prevents that effectively card pin phenomenon appears in needle when material has glass heat from chewing valve needle cover.
For achieving the above object, technical scheme provided by the utility model is: a kind of heat is chewed valve needle cover, and it comprises a body, and the middle part radial protrusion of described body forms a location boss, the bottom radial depressions forms a recess, and this recess is provided with the radial direction through hole that is connected with the endoporus of described body.
As a kind of improvement of the present utility model, the aperture of described radial direction through hole is less than the endoporus of described body.
As a kind of improvement of the present utility model, the endoporus upper end of described body enlarges gradually and forms one and extend out introduction part.
As a kind of improvement of the present utility model, the top and bottom of described body are provided with chamfering.
The beneficial effects of the utility model are: the utility model structural design is ingenious, reasonable, be equipped with recess and radial direction through hole, can prevent effectively that card pin phenomenon from appearring in needle when material has glass, not only guarantee to penetrate the normal operation of chewing, also effectively avoid chewing phenomenon because the card pin causes sizing material to stop up to penetrate, stability is high, and then increases work efficiency, and is provided with positioning boss, greatly simplified the dismounting operation, facilitate regular maintenance, time saving and energy saving, in addition, overall structure of the present utility model is simple, compact, 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.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Embodiment, referring to Fig. 1, a kind of heat that the present embodiment provides is chewed valve needle cover, it comprises a body 1, the middle part radial protrusion of described body 1 forms a location boss 2, and the bottom radial depressions forms a recess 3, and this recess 3 is provided with the radial direction through hole 4 that is connected with the endoporus 5 of described body 1.Be provided with positioning boss 2, greatly simplified the dismounting operation, facilitate regular maintenance, the aperture of time saving and energy saving described radial direction through hole 4 is less than the endoporus 5 of described body 1.The top and bottom of described body 1 are provided with chamfering.
During use, can be quick installed at by positioning boss 2 health of chewing that heat chews, easy to assembly, time saving and energy saving.During work, owing to being equipped with recess 3 and radial direction through hole 4, can prevent effectively that card pin phenomenon from appearring in needle when material has glass, not only guarantee to penetrate the normal operation of chewing, also effectively avoid chewing phenomenon because the card pin causes sizing material to stop up to penetrate, stability is high, and then increase work efficiency, and be provided with positioning boss 2, greatly simplified the dismounting operation, facilitate regular maintenance, time saving and energy saving.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change and revise above-mentioned embodiment.Therefore, the specific embodiment that discloses and describe above the utility model is not limited to also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although used some specific terms in this specification, these terms do not consist of any restriction to the utility model just for convenience of description.As described in the utility model above-described embodiment, adopt structure same or similar with it and other body of obtaining, all in the utility model protection domain.
Claims (4)
