Abstract
The utility model discloses a kind of needle valve type hot runner device, including body；A needle structure that mouth body runner inside middle is passed through positioned at the mouth body runner of body inside middle and one is provided with described body；The lower end of described needle structure is also associated with spreader structure, and spreader structure is connected between the described lower end of needle structure and the bottom of described body；Heating coil structures are additionally provided with described inner body wall；The lower end of described needle structure is additionally provided with cast gate department, for connecting at heat conduction to cast gate.The present apparatus is damascene structures, can make it that body is more abundant in heating, and be applied to large-scale injecting products, is also applied for the less product without material handle, and it is smaller that the mould of this device occupancy opens frame space, more convenient in mould installion.
Description
Technical field
Hot flow path injection molding technology field is the utility model is related to, particularly relates to a kind of needle valve type hot runner device.
Background technology
Process is developed rapidly in plastics industry industry, and the requirement of the outward appearance condition of large-scale injecting products production is increasingly
Strictly, and the flow distance of large-scale injection molding length could meet to rush using will open up multiple cast gates if common running gate system
The needs of mould flowing, and the carrier generally use split-type structural of hot flow path is formed, split-type structural is typically by body and hot-fluid
Road segmental structure is connected to form, no matter which kind of split-type structural inevitably has gap in junction, can trigger gap
Material leakage problem, along with the space for opening frame that large injection mold takes is also bigger, mould installion is inconvenient, so of the invention
A kind of Embedded hot runner structure of needle valve is provided, this device is applied to large-scale injecting products, is also applied for less without material handle
Product, it is also smaller that the mould that this device takes opens frame space, more convenient in mould installion.
Utility model content
In view of the foregoing, the utility model provides a kind of needle valve type hot runner device.
To reach above-mentioned purpose, technical scheme is used by the utility model solves its technical problem：
A kind of needle valve type hot runner device, including body；A mouth for being located at body inside middle is provided with described body
Body runner and one pass through mouth body runner inside middle needle structure；The lower end of described needle structure is also associated with shunting tatting
Structure, spreader structure are connected between the described lower end of needle structure and the bottom of described body；Described inner body wall
On be additionally provided with heating coil structures；The lower end of described needle structure is additionally provided with cast gate department, for connecting at heat conduction to cast gate.
Further feature is as follows for it：
The length of described needle structure is more than the length of described body.
Described heating coil structures are at least one.
It is connected through a screw thread between described spreader structure and mouth body runner.
Due to the utilization of above-mentioned technical proposal, the utility model provides a kind of needle valve type hot runner dress compared with prior art
To put, this structure is damascene structures, can make it that body is more abundant in heating, and this device is applied to large-scale injecting products,
Suitable for the less product without material handle, it is smaller that the mould that this device takes opens frame space, more convenient in mould installion.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
1, needle structure 2, body 3, mouth body runner 4, heating coil structures 5, spreader structure 6, cast gate department in figure.
Embodiment
In order that those skilled in the art more fully understand the technical scheme in the application, it is real below in conjunction with the application
The accompanying drawing in example is applied, the technical scheme in the embodiment of the present application is clearly and completely described, it is clear that described implementation
Example only some embodiments of the present application, rather than whole embodiments.It is common based on the embodiment in the application, this area
The every other embodiment that technical staff is obtained under the premise of creative work is not made, it should all belong to the application protection
Scope：
A kind of needle valve type hot runner device as shown in Figure 1, including body；It is located at body 2 provided with one in described body
The mouth body runner 3 and one of inside middle passes through the needle structure 1 of the inside middle of mouth body runner 3；The lower end of described needle structure 1
Spreader structure 5 is also associated with, spreader structure 5 is connected to the lower end and the bottom of described body 2 of described needle structure 1
Between；Heating coil structures are additionally provided with the described inwall of body 2；The lower end of described needle structure 1 is additionally provided with cast gate department 6, uses
At connection heat conduction to cast gate.
Further feature is as follows for it：
The length of described needle structure 1 is more than the length of described body 2.
Described heating coil structures are at least one.
It is connected through a screw thread between described spreader structure 5 and mouth body runner 3.
Heating body is carried out by heater first and reaches corresponding temperature to ensure the molten condition of sizing material, sizing material
Flow through the normal plastic emitting that mouth body runner realizes sizing material by mouth after heating, mouth can according to the specifications of plastic products and
Model is replaced accordingly, and this structure is damascene structures, can make it that body is more abundant in heating, this device is applied to
Large-scale injecting products, the less product without material handle is also applied for, it is smaller that the mould that this device takes opens frame space, in mould
It is more convenient in installation.
For above-described embodiment only to illustrate technical concepts and features of the present utility model, its object is to allow be familiar with technique
Personage can understand content of the present utility model and be carried out, the scope of protection of the utility model can not be limited with this,
All equivalent change or modifications made according to the utility model Spirit Essence, should all cover in the scope of protection of the utility model
It is interior.
