Abstract
A kind of nozzle point nozzle the invention discloses injection mold covers fit structure, including nozzle point and nozzle set, the nozzle are sheathed on nozzle point periphery, it is characterised in that the upper end surface of the nozzle point and nozzle set is in same level.The nozzle is arranged with a L-type heavy platform, and the nozzle point is equipped with to be stuck in the heavy platform for spacing and support with the matched shoulder of the heavy platform, the shoulder.The present invention can effectively solve the problems, such as nozzle point and heated seats binding face leak adhesive, convenient disassembly, and extend life of product, can reduce production cost.
Description
Technical field
The present invention relates to injection mold technology, the nozzle point nozzle set fit structure of especially a kind of injection mold.
Background technology
After the nozzle point nozzle set fit structure of current injection mold is as shown in Figure 1, nozzle point loads heated seats, then covered with nozzle logical
Cross screw thread screw reinforcing by nozzle point with heated seats end face kill sealing.One side nozzle point is screwed reinforcing by the screw thread that nozzle covers and is pressurized,
On the other hand extruded at high temperature by heated seats thermal expansion, nozzle point is completely in both ends compression, and in this case, nozzle point makes
Greatly shortened with the service life, nozzle tip surface leak adhesive situation often occur.In terms of dismounting, nozzle point is pushed down by nozzle set, but has torn nozzle set open
Afterwards, nozzle point is still trapped in heated seats, then is clamped nozzle point by pliers and taken out from heated seats, this many situation meetings of mode
Nozzle point is crushed.In addition, nozzle point and heated seats binding face leak adhesive, nozzle point and heated seats binding face leak adhesive, by nozzle set and heated seats
Extruding, nozzle point is easily bad, and nozzle point is often replaced in utilization, and replace it is more frequent, as the attrition component in dieparts,
It is of high cost；Nozzle point working environment is hot environment, and the material of nozzle point is beryllium copper, and the normal time works at high temperature so that nozzle point material
Soften as annealed condition, coordinate with heated seats end face and occur collapsing or be not bonded；And dismounting is inconvenient, when nozzle set is pulled down,
Nozzle point is also trapped in heated seats.The present invention comes therefrom.
The content of the invention
In view of the deficienciess of the prior art, the present invention provides a kind of nozzle point nozzle set fit structure of injection mold, the note
The nozzle point nozzle set fit structure of mould can effectively solve the problems, such as nozzle point and heated seats binding face leak adhesive, and extend the product longevity
Life, reduces production cost.
The technical scheme is that：
A kind of nozzle point nozzle set fit structure of injection mold, including nozzle point and nozzle set, the nozzle are sheathed on nozzle point periphery, its
It is characterized in that, the upper end surface of the nozzle point and nozzle set is in same level.
Preferably, the nozzle is arranged with a L-type heavy platform, the nozzle point be equipped with the matched shoulder of the heavy platform, it is described
Shoulder, which is stuck in the heavy platform, is used for spacing and support.
Preferably, a heated seats, the lower face of the heated seats while the upper surface covered with nozzle point and nozzle are further included
Contact.
Preferably, the nozzle is arranged with locking thread and is used to fix the nozzle point.
The advantage of the invention is that：
1st, nozzle point and heated seats binding face leak adhesive are solved the problems, such as；
2nd, solve nozzle point to be extruded with heated seats by nozzle set, nozzle point modification, perishable problem.
3rd, it is hot environment to solve nozzle point working environment, and the normal time works at high temperature so that nozzle point material softens to move back
Fiery state, coordinates with heated seats end face and occurs collapsing or be not bonded problem.
4th, it is inconvenient to solve dismounting, when nozzle set is pulled down, the problem of nozzle point is also trapped in heated seats.
5th, solve and replace the off-time that nozzle point is influenced, reduce the replacement frequency of nozzle point, reduction and dieparts
Cost, improves the production output value, reduces production cost.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the schematic diagram of the nozzle point nozzle set fit structure of the injection mold of the prior art.
Fig. 2 is the structure diagram of the present invention.
Wherein, sharp 2. nozzles of 1. nozzles cover 3. heavy platforms 4. locking thread.
Embodiment
To make the present invention more readily apparent understandable, hereby it is illustrated with a preferred embodiment combination attached drawing.
Fig. 1 is one embodiment of the present invention, and the nozzle point nozzle set fit structure of the injection mold includes nozzle point 1 and nozzle
Set 2, the nozzle set 2 are sheathed on sharp 1 periphery of nozzle, it is characterised in that the upper end surface of the nozzle point 1 and nozzle set 2 is in same level
Face.
Preferably, the nozzle is arranged with a L-type heavy platform 3, and the nozzle point 1 is equipped with and the 3 matched shoulder of heavy platform, institute
State shoulder and be stuck in the heavy platform 3 and be used for spacing and support.
Preferably, a heated seats are further included, the lower face of the heated seats covers 2 upper end with nozzle point 1 and nozzle at the same time
Face contacts.
Preferably, the nozzle set 2 is equipped with locking thread 4 and is used to fix the nozzle point 1.
Design principle of the present invention：
Nozzle set 2 does heavy platform 3, allows nozzle point 1 to sink to completely in nozzle set 2, and during assembling, nozzle point 1 is initially charged with nozzle set 2 to be passed through again
Nozzle external threading screws reinforcing and nozzle is covered sharp 1 end face of 2 nozzles and the pressing contact sealing at the same time of heated seats end face；In this way, nozzle external threading revolves
Tight reinforcing directly contacts compression with heated seats, plays protection and support nozzle point 1, also plays position-limiting action；It is swollen to carry out heated seats heat
Swollen power directly reflects nozzle set 2, also functions to protection nozzle point 1 and acts on, so as to solve prior art nozzle point nozzle set fit form (as schemed
Shown in 1) occur variety of problems.And dismounting is more convenient, tearing nozzle set 2 open will together split out nozzle point 1, will not be nozzle point 1
It is trapped in heated seats, it is easy to replace, and will not damage nozzle point so as to influence life of product.
It is pointed out that as described above is only to explain the preferred embodiments of the invention, it is right according to this to be not intended to
The present invention makees limitation in any form, therefore all have any modification for making the related present invention under identical spirit
Or change, it should all be included in the category that the invention is intended to protect.
