Abstract

The utility model relates to a three-way type glue feeding nozzle. The three-way type glue feeding nozzle comprises a nozzle tip body (1), a glue feeding channel (2) and a valve needle through hole (4), wherein the nozzle tip body (1) is of a hollow structure, at least three longitudinal glue feeding channels (3) are formed in the inner wall of the nozzle tip body (1), the cross sections of the glue feeding channels (3) are of sector structures with rounded corners, valve needle guiding bosses (2) are formed between the adjacent glue feeding channels (3), each valve needle guiding boss (2) is provided with a matching surface (5), the multiple matching surfaces (5) are located on the same cylindrical surface, and the valve needle through hole (4) is formed in the center position of the nozzle tip body (1). The three-way type glue feeding nozzle has the advantages that the three-way type glue feeding nozzle is simple in structure, the valve needle and a valve tip are precisely matched with each other, the temperature of the valve tip is effectively reduced, and energy sources are saved.

Description

Three-clove style enters Jiao Zui

Technical field

The utility model relates to technical field of mold, and particularly three-clove style enters Jiao Zui.

Background technology

Along with the development of technology, the kind of mould is more and more, because many parts are difficult to processing on general lathe, therefore mostly need to process by the mode of injection moulding.

Traditional infusion bottle mould adopts single-point to enter glue, from chewing sharp injecting glue, enter notes chamber, when injecting glue, chew tip temperature high, energy consumption is large, and chews sharp service life and reduce, chew the speed quickening that point is worn, chew coordinating along with the production time increases between point and needle, its quality of fit also declines, and affects product quality.

Utility model content

The purpose of this utility model is to overcome the shortcoming of prior art, a kind of simple in structure, needle is provided and chews point and coordinate accurate and effectively reduce the three-clove style of chewing sharp temperature and the saving energy and enter Jiao Zui.

The purpose of this utility model is achieved through the following technical solutions: three-clove style enters Jiao Zui, it comprises chews sharp body, enters glue passage and needle through hole, chewing sharp body is hollow structure, chew and on the inwall of sharp body, offer longitudinally at least three and enter glue passage, adjacent two are entered between glue passage, to form needle guide ledges, on each needle guide table, be provided with mating surface, the center of chewing sharp body is provided with needle through hole.

The described cross section that enters glue passage is the sector structure with fillet.

Described a plurality of mating surfaces are positioned on the same face of cylinder.

The utlity model has following advantage:

1, chewing three breach that offer on point along entering glue direction, the part of its protrusions coordinates with needle, realizes guide effect, from breach, enters glue, and it is simple in structure.

2, the mating surface of needle guide ledges is circular arc, realizes and to closely cooperate with needle, and guidance quality is good, needle with chew point and coordinate precision.

3, adopt three-clove style to enter the mode of glue, effectively reduce and chew tip temperature, increase and chew sharp service life, and can effectively reduce energy resource consumption.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is A-A sectional structure schematic diagram in Fig. 1;

Fig. 3 is perspective view of the present utility model;

In figure: 1-chews sharp body, 2-needle guide ledges, 3-enters glue passage, 4-needle through hole, 5-mating surface.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.

As shown in Figure 1, Figure 2 with shown in Fig. 3, three-clove style enters Jiao Zui, it comprises chews sharp body 1, enters glue passage 2 and needle through hole 4, chewing sharp body 1 is hollow structure, chew and on the inwall of sharp body 1, offer longitudinally at least three and enter glue passage 3, adjacent two are entered between glue passage 3 to form needle guide ledges 2, on each needle guide table 2, are provided with mating surface 5, and the center of chewing sharp body 1 is provided with needle through hole 4.

The cross section that enters glue passage 3 is the sector structure with fillet; A plurality of mating surfaces 5 are positioned on the same face of cylinder, and mating surface 5 coordinates with needle.
