Utility model content
The purpose of this utility model is to provide a kind of needle valve type hot runner structure, adopts monoblock type hot runner structure to overcome admirably and leaks material problem, and be beneficial to formation one assembly, installs very simple and efficient.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of needle valve type hot runner structure, comprises that heat chews body, needle and cylinder; Described heat is chewed and in body, is offered hot flow path, this hot flow path is divided into connected side segmentation and valve segmentation, the free port of this side segmentation is the feeding mouth of described hot flow path, the discharging opening that the free port of described valve segmentation is described hot flow path, and this feeding mouth axially mutually staggers with discharging opening and is parallel; One end being connected with described side segmentation of described valve segmentation offers needle mouth, and described needle is stretched in valve segmentation by this needle mouth, and stretch out outside described needle mouth the outer end of this needle, and described cylinder is connected with the outer end of described needle by a plate.
Described side segmentation is L-type runner, the vertical connection of corresponding one end of the discharge end of this L-type runner and described valve segmentation.
Described needle mouth is provided with a valve needle cover, and this valve needle cover correspondence is set in outside described needle.
Described connecting plate comprises substrate and connecting bridge, on this substrate, offer impenetrating mouth, described connecting bridge is " Jiong " type shape, and it is erected on the relative dual-side of described impenetrating mouth, this connecting bridge is provided with assembly hole, and the outer end of described needle is passed described impenetrating mouth and is installed on described assembly hole.
Adopt after such scheme, the utility model is with respect to the beneficial effect of prior art: hot flow path adopts monolithic construction, be that hot flow path only need be opened in heat and chews on body, hot flow path is divided into side segmentation and valve segmentation, side segmentation and valve segmentation meet feeding mouth and discharging opening axially parallel arranges under requirement, adopt ingenious shifting to install, make one end of valve segmentation can form needle mouth and be assembled into for needle adaptation; This monoblock type hot flow path has been avoided slit source material problem well.Cylinder drives needle activity by connecting plate, and cylinder adopts common standard cylinder, not affected by system temperature, ensures system normal operation and service life.This novel whole hot runner structure is succinct, can be assembled into an assembly, when installation, only assembly directly need be installed in mould, very simple and efficient.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this case is described in further detail.
This case relates to a kind of needle valve type hot runner structure, as Figure 1-4, mainly comprises that heat chews body 1, needle 2 and cylinder 6.Heat is chewed in body 1 and is offered hot flow path, this hot flow path is divided into connected side segmentation 11 and valve segmentation 12, the free port of side segmentation 11 is the feeding mouth 111 of hot flow path, the free port of valve segmentation 12 is the discharging opening 121 of hot flow path, this feeding mouth 111 and discharging opening 121 are axially and mutually stagger and parallel, meet the direction setting of traditional moulds hot flow path material mouth.One end being connected with side segmentation 11 of valve segmentation 12 offers needle mouth 122, needle 2 is stretched in valve segmentation 12 by needle mouth 122, the inner end of needle 2 extends discharging opening 121, stretch out outside needle mouth 122 outer end 21 of needle 2, and described cylinder 6 is connected with the outer end 21 of needle 2 by a plate 4.
Described valve segmentation 12 is the line flowing channel corresponding with needle 2, and side segmentation 11 1 preferred embodiments are L-type runner, the vertical connection of corresponding one end of the discharge end of this L-type runner and valve segmentation 12.
Preferably, needle mouth 122 is provided with a valve needle cover 3, and these valve needle cover 3 correspondences are set in outside needle 2, and valve needle cover 3 coordinates with needle 2, avoids leaking material herein.
