Abstract
The utility model discloses a kind of grommet nut injection moulds, including fixed die insert and moving die insert, nut is provided on the fixed die insert and fixes core, the end set that the nut fixes core has grommet nut fixed part, and the fixing end of grommet nut fixed part is provided with clamping plane；One group of axially disposed telescopic chute is provided on grommet nut fixed part, telescopic chute is extended to from the end of grommet nut fixed part on clamping plane.The utility model can be good at solving the problems, such as the embedded grommet nut in blind hole is molded, and can eliminate the mismachining tolerance of grommet nut itself, prevents injection material from entering in grommet nut, can be widely applied to injection molding field.
Description
Technical field
The utility model is related to injection mould field, more particularly, to a kind of grommet nut injection mould.
Background technology
In injection molding, some inserts are often put into meet different functional requirements.The embedded spiral shell in moulding
Mother is relatively common structure, but existing nut is arranged in the through-hole of moulding, all relatively good fixation in such both ends, convenient
Processing positioning.However, for the blind hole in moulding is required to be embedded in for grommet nut, due to blind hole structure, in injection mould
Upper grommet nut can not be fixed, therefore, it has not been convenient to process.
Utility model content
The purpose of this utility model is to provide a kind of grommet nut injection mould, solves existing grommet nut insertion injection
In the blind hole of part, the problem of inconvenient is processed.
Technical solution is used by the utility model solves its technical problem：A kind of grommet nut injection mould, packet
Fixed die insert and moving die insert are included, nut is provided on the fixed die insert and fixes core, the nut fixes the end of core
Grommet nut fixed part is provided with, the fixing end of grommet nut fixed part is provided with clamping plane, the grommet nut fixed part
For contractile elastic construction.
Preferably, it is provided with one group of axially disposed telescopic chute on grommet nut fixed part, telescopic chute is from grommet nut
The end of fixed part is extended on clamping plane.
Further, the height of the grommet nut fixed part is not more than the hole depth of grommet nut.
To reduce the loss to grommet nut when mold is debugged, rotating flow is additionally provided on the moving die insert
Road is provided on moving die insert and is molded into type groove with what grommet nut size was adapted.
The beneficial effects of the utility model：The utility model fixes core by the nut on fixed die insert and fixes blind hole spiral shell
Mother realizes the processing of inserts, has the advantages of easy to assembly, stability is good.Meanwhile the grommet nut fixed part is using elasticity
Structure design can eliminate the mismachining tolerance of grommet nut in itself, ensure that the blind hole of grommet nut fixed part and grommet nut is matched
Closing closely, prevents the injection material in injection molding from flowing into the blind hole of grommet nut.The height of the grommet nut fixed part
No more than the hole depth of grommet nut, the end face of grommet nut is allow to be pressed on clamping plane, further improves grommet nut
Leakproofness.Eddy channel on the moving die insert and type groove is molded into, a batch and blind hole spiral shell can processs in mold die trial
The identical moulding of parent structure size is sleeved on grommet nut fixed part, and the use waste of grommet nut, reduces when reducing die trial
Cost；Ensure that grommet nut fixed part does not have injection material inflow in die trial simultaneously.
Below with reference to drawings and examples, the utility model is described in detail.
Description of the drawings
Fig. 1 is the vertical view of the utility model fixed die insert.
Fig. 2 is the structure diagram that nut fixes core in the utility model.
Fig. 3 is the vertical view of the utility model moving die insert.
Specific embodiment
Embodiment, as shown in Figures 1 to 3, a kind of grommet nut injection mould, including fixed die insert 1 and moving die insert 2,
Nut is provided on the fixed die insert 1 and fixes core 3, the end set that the nut fixes core 3 has grommet nut to fix
Portion 31, the fixing end of grommet nut fixed part 31 are provided with clamping plane 32, and the grommet nut fixed part 31 is contractile
Elastic construction, specifically, be provided with one group of axially disposed telescopic chute 33 on grommet nut fixed part 31, telescopic chute 33 is from blind
The end of hole nut fixed part 31 is extended on clamping plane 32, which makes grommet nut fixed part 31 have centainly
Shrinkage.The structure is avoided that the mismachining tolerance of grommet nut itself, ensures that grommet nut coordinates with grommet nut fixed part 31
Closely.The height of the grommet nut fixed part 31 is not more than the hole depth of grommet nut.Grommet nut is sleeved on grommet nut and fixes
In portion 31, end is made to lean against in pressure planes 32.During processing, grommet nut is sleeved on grommet nut fixed part 31, prevents from noting
Material enters in grommet nut during modeling, meanwhile, have and can be good at fixed grommet nut.
Eddy channel 4 is additionally provided on the moving die insert 2, is provided on moving die insert 2 and grommet nut size phase
Adaptation is molded into type groove 5.In the mold die trial stage, injection material can be guided to by eddy channel and be molded into type groove 5,
Injection a batch moulding identical with grommet nut size is spare.When die trial, eddy channel is turned to and is connected with movable model type
It connects, then nut will be sleeved on by the moulding of injection molding and is fixed on core instead of grommet nut, grommet nut can be reduced
Usage amount avoids waste during die trial, reduces cost, meanwhile, and be avoided that during die trial and cause injection article without grommet nut
Material enters nut fixed in-core.
