Description
Technical field
The invention relates to punch forming manufacture fields, and more particularly, to a kind of spark plug production mould.
Background technology
In the production of iridium alloy spark plug, spark-discharge tip often has a certain degree with pedestal, and its bending angle
The molding control of degree is completed by mold.In punch forming, iridium product needs occur bending and deformation, crooked position and benchmark
Relative deformation occurs for face, and deformation generates fulcrum often through molding die, and generates pressure to the product at fulcrum both ends by mold
Power completes flexural deformation.
Conventional punch mold controls bending by upper die and lower die tool, and the flat segments near bending is often made also to occur
Bending.When product specifications are smaller, the bending for being bent neighbouring flat segments often causes the huge deviation of product size, makes system
Product do not meet production assembly demand.
Invention content
The embodiment of the present application proposes a kind of mold of spark plug production, can improve production of articles assembly demand.
The embodiment of the present application provides a kind of mold of spark plug production, which includes：Upper mold, the upper mold include upper mold core
With upper mold housing, concordantly and to be annular, the bottom of the upper mold core for circle and is placed in the annular inboard for the bottom of the upper mold housing,
And the upper mold housing can be moved with respect to the upper mold core；Lower die, the lower die generate the fire for agreeing with extruded product with the upper mold
Hua Sai.
In some possible realization methods, which further includes：Screw thread, the screw thread is for connecting the upper mold core and this
Mould housing.
In some possible realization methods, which further includes：Disc spring, the disc spring is for connecting the screw thread and the upper mold
Core.
In some possible realization methods, which further includes：Cam, the cam are used to control the bottom of the upper mold housing
Portion position.
In some possible realization methods, which is iridium alloy material.
Based on said program, the mold of the spark plug production of the embodiment of the present application includes upper mold, which includes upper mold core
With upper mold housing, concordantly and to be annular, the bottom of the upper mold core for circle and is placed in the annular inboard for the bottom of the upper mold housing,
And the upper mold housing can be moved with respect to the upper mold core；Lower die, the lower die generate the fire for agreeing with extruded product with the upper mold
Hua Sai can improve production of articles assembly demand.

Specific implementation mode
Below in conjunction with attached drawing, technical solutions in the embodiments of the present application is described.
Upper mold is shape shown in FIG. 1 in traditional scheme, and lower die is shape shown in Fig. 2, is put between upper die and lower die
Enter product, spark plug shape shown in Fig. 3 can be produced by squeezing the product.When the specification of spark plug is smaller, fire
Bending at the top of Hua Sai can have an impact production assembly.Therefore, how to avoid the bending of spark plug tip urgently to be resolved hurrily.
Fig. 4 is the schematic diagram of the spark plug production mould 400 of the embodiment of the present application.
The mold 400 includes upper mold 410 and lower die 420, and wherein upper mold 410 includes upper mold core 411 and upper mold housing 412.
The bottom of upper mold housing 412 is concordant and circularizes, and upper mold core 411 is placed in annular inboard, and the upper mold housing 412 can relatively on
Mold core 411 moves.Lower die 420, which is used to agree with extruded product with upper mold 410, generates spark plug.
Specifically, the bottom of upper mold core 411 can be less than the bottom of upper mold housing 412, that is to say, that in the extruding system of progress
When product, upper mold core preferential contact product.Lower die 420 with upper mold 410 for agreeing with, i.e., the position of upper mold protrusion, lower die are recessed；On
The position of mould recess, upper mold protrusion.In this way due to 411 preferential contact product extruded product of upper mold core, then move upper mold housing 412
Product is contacted, protrusion at the top of product is avoided, that is, avoids spark plug tip from protruding.
For example, making the spark plug produced as shown in figure 5, to reduce to production by adding upper mold core in mold
The influence of assembly.
It should be understood that the upper mold core can be fixed, upper mold housing can move.
Optionally, upper mold core 411 is placed on the inside of the base circle of upper mold housing 412, can be filled up completely, be can also be
Centre has the gap, and specific upper mold core radius size can flexibly be set according to demand, and the application is to this without limiting.
Optionally, upper mold core 411 can be confined on upper mold housing 412 by screw thread 430.
Specifically, when producing spark plug, by adjusting screw thread upper mold core can be protruded.Upper mold core can also in this way
It is mobile such as idle in the mold, it is recoverable to the upper mold core and avoids collision, facilitate collection.
Optionally, upper mold core 411 can be combined with 412 nesting of upper mold housing, and the application is to this without limiting.
Optionally, upper mold core 411 can also by disc spring 440 be threadedly coupled.For example, as shown in Figure 6.
After upper mold core contacts product, upper mold housing continues to move down, and upper mold core is by the pressure of disc spring in turn to article center
Pressure is generated, in this way after upper mold housing and product into contact, the top of product will not protrude.
Optionally, upper mold housing 412 can be moved with respect to upper mold core, can be controlled by cam 450.
Specifically, operating lever can be set on cam, the bottom position that cam makes upper mold housing is controlled by operating lever
It sets and changes.
It should be understood that when controlling the movement of upper mold housing by cam, the bottom position of upper mold core is not impacted, i.e., at this time
Upper mold core can not change.
The above, the only specific implementation mode of the application, but the protection domain of the application is not limited thereto, it is any
Those familiar with the art can easily think of the change or the replacement in the technical scope that the application discloses, and should all contain
It covers within the protection domain of the application.Therefore, the protection domain of the application shall be subject to the protection scope of the claim.
