Abstract
The utility model discloses a kind of through-hole nut injection moulds, fixed die insert and moving die insert including mutual cooperation, quick connector is fixedly installed on the moving die insert, the moving core being connect with quick connector is additionally provided with, the moving core includes the fixed part coordinated with quick connector and the threaded shank coordinated with through-hole nut；The length of the threaded shank is identical with the hole depth of through-hole nut, and threaded shank is provided with confined planes with fixed part junction.The utility model sets one group of moving core being adapted with through-hole nut by setting quick connector on moving die insert, and moving core coordinates with nut, ensures that injection material may not flow into through-hole nut in processing.Solve the problems, such as that through-hole nut is inconvenient to fix, and simple in construction, easy to disassemble and assemble in blind hole is molded simultaneously, it is high in machining efficiency.It can be widely applied to injection mould field.
Description
Technical field
The utility model is related to injection mould manufacture field, more particularly, to a kind of through-hole 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 through-hole nut, due to blind hole structure, in injection mould
Upper through-hole nut can not be fixed, and work in-process injection material is easy to enter in through-hole nut, therefore, for this kind of moulding
It processes very inconvenient.
Utility model content
The purpose of this utility model is to provide a kind of through-hole nut injection mould, and it is blind that solution through-hole nut is arranged on injection
It is fixed inconvenient in hole, the problem of injection material easily enters in through-hole nut.
Technical solution is used by the utility model solves its technical problem：A kind of through-hole nut injection mould, packet
Include the fixed die insert and moving die insert of mutual cooperation, quick connector be fixedly installed on the moving die insert, be additionally provided with soon
The moving core of connection-peg connection, the moving core include the fixed part that coordinates with quick connector and coordinate with through-hole nut
Threaded shank；The length of the threaded shank is identical with the hole depth of through-hole nut, and threaded shank is provided with confined planes with fixed part junction.
Further, the quick connector includes fixed link and the sleeve being arranged in fixed link, the moving core
Fixed part is adapted with sleeve.
For convenience of fixation, the centre position of the fixed link is provided with the clamping groove coordinated with fixed die insert.
To realize quick grafting, the endoporus of the sleeve is quadrilateral structure, the fixed part for end size it is small, with
The big grading structure of one end size of threaded shank connection, and it is provided with four inclined-planes coordinated with sleeve；The minimum ruler of fixed part
The very little size less than hub internal bore, full-size are more than the size of hub internal bore.
The beneficial effects of the utility model：The utility model sets one by setting quick connector on moving die insert
The moving core that group is adapted with through-hole nut, moving core coordinate with nut, ensure that injection material may not flow into processing
In through-hole nut.Meanwhile fast inserting structure conveniently machine after quickly moving core is detached with moving die insert, then with manually
Or electric sleeve barrel tool detaches moving core with the through-hole nut being moulded on moulding.Why quick connector uses sleeve
Structure is quickly taken out from through-hole nut moving core using manually or automatically sleeve barrel tool after exactly facilitating separation.
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 fixed die insert in the utility model.
Fig. 2 is the fiting relation figure of the utility model moving core and quick connector.
Specific embodiment
Embodiment, as shown in Figure 1 and Figure 2, a kind of through-hole nut injection mould, the fixed half and moving half including mutual cooperation,
Fixed die insert 1 is provided on the cover half, moving die insert is provided on the dynamic model, is fixedly installed on the moving die insert fast
Connection-peg 2, is additionally provided with the moving core 3 being connect with quick connector 2, and the moving core 3 includes what is coordinated with quick connector 2
Fixed part 32 and the threaded shank 31 with the cooperation of through-hole nut；The length of the threaded shank 31 is identical with the hole depth of through-hole nut, spiral shell
Bar portion 31 is provided with confined planes 33 with 32 junction of fixed part.The quick connector 2 includes fixed link 21 and is arranged on fixed link
Sleeve 22 on 21, the fixed part 32 of the moving core 3 are adapted with sleeve 22.The centre position setting of the fixed link 21
There is the clamping groove 23 coordinated with fixed die insert 1.The endoporus of the sleeve 22 is quadrilateral structure, and the fixed part 32 is end
The big grading structure of size is small, is connect with threaded shank 31 one end size, and it is provided with four inclined-planes coordinated with sleeve 22；Gu
The minimum dimension for determining portion 32 is less than the size of 22 endoporus of sleeve, and full-size is more than the size of 22 endoporus of sleeve.
In use, through-hole nut first to be screwed in the threaded shank of moving core, storage is spare.When being molded, beat
Mold will be packed into equipped with the moving core of through-hole nut in quick connector, mold-closing injection molding.Mould is opened after the completion of injection
Tool, at this time since nut has been moulded in moulding, during die sinking moving core together with through-hole nut in moving die insert
Quick connector detaches, and then manually or electrically sleeve barrel tool takes out moving core for use next time from moulding.
The structure solves the problems, such as that through-hole nut is inconvenient to fix in blind hole is molded, while it is logical to be also avoided that injection material enters
In the nut of hole, and it is simple in construction, easy to disassemble and assemble, it is high in machining efficiency.
