Description
Technical field
The utility model is related to a kind of thimble structures of automotive ventilation grid injection mould.
Background technology
The main function of automotive ventilation grid is that water tank, engine, the perflation ventilation of air-conditioning etc. prevent external in traveling
Destruction of the object to interior component.For the requirement of automobile lightweight, some present automotive ventilation grids are to pass through injection molding
Injection-molded item made from mold, injection-molded item must take out from mold cavity after shaping, and complete this and take out injection molding system
The mechanism of product action is ejecting mechanism.Common ejecting mechanism is ejected injection-molded item by thimble rod, but traditional thimble
Structure is difficult to install, when thimble rod needs repairing and replaces, need to dismantle mold or entire push pin device, extremely inconvenient.
Utility model content
It is reasonable for structure the purpose of this utility model is to provide a kind of thimble structure of automotive ventilation grid injection mould,
By connecting thimble extension bar on thimble rod, replaces thimble rod to eject injection-molded item by thimble extension bar, be effectively protected thimble
Bar；Also, the stable connection of thimble rod and thimble extension bar.
To achieve the above object, the technical solution of the utility model is to design a kind of thimble of automotive ventilation grid injection mould
Structure, including thimble rod and the thimble extension bar right over thimble rod, and the lock for connecting thimble rod and thimble extension bar
Tight mechanism；Thimble extension bar lower end is equipped with the bulge loop of diameter convex, which is equipped with several screw holes, several screw hole edges
The circumferencial direction of bulge loop is uniformly distributed；The thimble rod epimere has external screw thread, and the retaining mechanism includes locking nut, the locking screw
For mother by being connected in thimble rod with the external screw thread, which protrudes the top surface of locking nut, and the thimble rod
Upper end is butted on above-mentioned thimble extension bar lower end；Deformation gap is formed between the locking nut and above-mentioned bulge loop, on the locking nut
Equipped with several through-holes, each through-hole are equipped with screw with corresponding screw hole correspondingly with above-mentioned several screw holes.In said program
In, by connecting thimble extension bar on thimble rod, replaces thimble rod to eject injection-molded item by thimble extension bar, be effectively protected top
Shank only need to back out screw, can take out thimble extension bar when needing to dismantle thimble extension bar.In addition, due to locking nut with it is convex
Deformation gap is formed between ring, when tightening through-hole with the screw in corresponding screw hole, locking nut will slightly be leaned on towards bulge loop
Hold together, so that the screw thread of locking nut is compressed the external screw thread of thimble rod, considerably increase the frictional force between screw thread, you can reach locking
Purpose so that thimble rod is bonded with thimble extension bar.
Preferably, thimble extension bar upper surface is provided with circular groove, which is built-in with elastic component.By using
Said program, by elastic component contact product, elastic component can play the role of buffering, not only protect product, also improve thimble
The service life of extension bar.
Preferably, the quantity of the screw hole is 4, correspondingly, the quantity of the through-hole is 4.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model.
Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and the protection model of the utility model cannot be limited with this
It encloses.
The utility model specific implementation technical solution be：
As shown in Figure 1, a kind of thimble structure of automotive ventilation grid injection mould, including thimble rod 1 and positioned at thimble rod 1 just
The thimble extension bar 2 of top, and the retaining mechanism for connecting thimble rod 1 and thimble extension bar 2；2 lower end of thimble extension bar is set
There is the bulge loop 3 of diameter convex, which is equipped with several screw holes, and several screw holes are uniformly distributed along the circumferencial direction of bulge loop 3；Institute
State 1 epimere of thimble rod have external screw thread, the retaining mechanism includes locking nut 4, the locking nut 4 by with the external screw thread
It is connected in thimble rod 1, which protrudes the top surface of locking nut 4, and 1 upper end of thimble rod is butted on above-mentioned top
2 lower end of needle extension bar；Between the locking nut 4 and above-mentioned bulge loop 3 formed deformation gap 5, the locking nut 4 be equipped with it is above-mentioned
Several screw holes several through-holes correspondingly, each through-hole with screw 6 is installed in corresponding screw hole.In the above scheme, by
Thimble extension bar 2 is connected on thimble rod 1, is replaced thimble rod 1 to eject injection-molded item by thimble extension bar 2, is effectively protected thimble rod
1, when needing to dismantle thimble extension bar 2, screw 6 only need to be backed out, thimble extension bar 2 can be taken out.In addition, due to locking nut 4 with
Deformation gap 5 is formed between bulge loop 3, when tightening through-hole with the screw 6 in corresponding screw hole, locking nut 4 will be towards bulge loop 3
It draws close slightly, so that the screw thread of locking nut 4 is compressed the external screw thread of thimble rod 1, considerably increase the frictional force between screw thread, you can
Achieve the purpose that locking so that thimble rod 1 is bonded with thimble extension bar 2.
Also, the quantity of above-mentioned screw hole is 4, correspondingly, the quantity of above-mentioned through-hole is 4.
In addition, above-mentioned 2 upper surface of thimble extension bar is provided with circular groove, which is built-in with elastic component.By using
Said program, by elastic component contact product, elastic component can play the role of buffering, not only protect product, also improve thimble
The service life of extension bar 2.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
The scope of protection of the utility model is also should be regarded as into retouching.
