Description
Technical field
This utility model is related to a kind of automobile die, specifically a kind of injection mold of automobile thread plate.
Background technology
In vehicle automobile production, the production of thread plate, typically by machining making, passed through boring machine before this
Boring, then carries out tapping processing by tapping machine device to hole, thus being processed into screwed hole it is clear that mechanical processing steps are more, plus
Work is cumbersome, and quality is also bad simultaneously, and efficiency is not very high it is therefore desirable to a kind of obtain automobile thread by injection molding manner
The injection mold of plate.
Utility model content
The purpose of this utility model is in view of the shortcomings of the prior art, provides a kind of automobile thread plate rational in infrastructure
Injection mold.
A kind of technical scheme: the technical scheme that this utility model solve problem is adopted is: injection mould of automobile thread plate
Tool, including base, the both sides of described base are provided with support bar, and the upper end of described support bar is provided with mold, described
The middle part of mold be provided with the die cavity of concave downward, and the right-hand member of described mold is hinged with the mould for covering die cavity
Tool cover plate；The right end face of described mold is provided with injection channel, and this injection channel extends in die cavity to the right；And mould
The left side of tool cover plate is additionally provided with injection hole, and this injection hole is rear on die cover plate lid to be communicated with injection channel, die cover plate
Right side is provided with air vent；Described die cover plate is additionally provided with corresponding screwed hole with the bottom of chamber plate of die cavity；Screw thread in the hole is pacified
Equipped with the screw rod that can disassemble, the upper end of screw rod is provided with nut, insertion whole upper and lower when described screw rod is installed
Screwed hole.
Further, the middle part of described die cover plate is provided with air vent；Injected plastics material is poured into through injection from injection hole
Passage flows in die cavity, and in order to prevent from producing bubble when injection, the injection quality of impact screw thread, therefore in die cover
The middle part of plate is opening up an air vent.
Further, in order that mold and die cover plate can be good at mounting and dismounting；Described mold and mould
The left end of tool cover plate is fixed together by snap close piece.
Beneficial effect: for this utility model is compared to traditional technical scheme, have the advantages that
This utility model first passes through snap close piece when use and mold and die cover plate is fixed together, and is pouring note into
Before moulding material, with screw rod, the screwed hole insertion on die cover plate and mold is shut, injected plastics material is after injection hole inflow
Gradually fill full die cavity, also the screw rod in die cavity is integrally wrapped up, after waiting injected plastics material cooling, wrap the part of screw rod
It is the formation of screwed hole, when disassembling the thread plate of molding in die cavity, needing to turn nut makes screw rod overall
Rotate it is possible to back-out screw rod, then die cover plate is opened the thread plate that can be obtained by injection mo(u)lding, therefore this practicality
New injection mold structure rationally, can make thread plate by injection mo(u)lding, and improve product quality and work efficiency.
Brief description
Fig. 1 is this utility model structural representation.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with this utility model, the present embodiment is with this utility model
Implemented under premised on technical scheme it should be understood that these embodiments are merely to illustrate this utility model rather than limit this reality
With new scope.
As shown in figure 1, a kind of injection mold of automobile thread plate, including base 1, the both sides of described base 1 are provided with
Support bar 2, the upper end of described support bar 2 is provided with mold 3, and the middle part of described mold 3 is provided with concave downward
Die cavity 4, and the right-hand member of described mold 3 is hinged with the die cover plate 5 for covering die cavity 4；The right-hand member of described mold 3
Surface is provided with injection channel 6, and this injection channel 6 extends in die cavity 4 to the right；And the left side of die cover plate 5 is additionally provided with
Injection hole 7, this injection hole 7 is communicated with injection channel 6 after die cover plate 5 covers, and the right side of die cover plate 5 is provided with air vent
8；Described die cover plate 5 is additionally provided with corresponding screwed hole 9 with the bottom of chamber plate of die cavity 4；It is provided with screwed hole 9 and can dismantle
The screw rod 10 getting off, the upper end of screw rod 10 is provided with nut 11, the screw thread of insertion whole upper and lower when described screw rod 10 is installed
Hole 9.
The middle part of described die cover plate 5 is provided with air vent 8；Injected plastics material is poured into from injection hole 7 and is flowed through injection channel 6
Enter to die cavity 4, in order to prevent from producing bubble when injection, the injection quality of impact screw thread, therefore in die cover plate 5
Middle part is opening up an air vent 8.
In order that mold 3 and die cover plate 5 can be good at mounting and dismounting；Described mold 3 and die cover plate 5
Left end be fixed together by snap close piece 12.
This utility model first passes through snap close piece when use and mold and die cover plate is fixed together, and is pouring note into
Before moulding material, with screw rod, the screwed hole insertion on die cover plate and mold is shut, injected plastics material is after injection hole inflow
Gradually fill full die cavity, also the screw rod in die cavity is integrally wrapped up, after waiting injected plastics material cooling, wrap the part of screw rod
It is the formation of screwed hole.
When disassembling the thread plate of molding in die cavity, needing to turn nut makes screw rod unitary rotation, such as
The comparison that fruit screw rod is glued by the injected plastics material in die cavity is tight, when being difficult to take off, can be made by gently beaing screw rod up and down
It produces and loosens, then back-outs by screw rod by rotation, then die cover plate is opened the thread plate that can be obtained by injection mo(u)lding,
Injection mold structure therefore of the present utility model rationally, can make thread plate by injection mo(u)lding, and improve product quality
And work efficiency.
Above-mentioned specific embodiment is a preferred embodiment of the present utility model, is not new for limiting this practicality
The enforcement of type and right, it is equivalent that the content described in all foundation this utility model patent protection scopes is made
Change and modification, all should be included in this utility model patent claim.
