Specific embodiment
Many details are explained in the following description in order to fully understand the application.But the application can be with
Much it is different from other way described herein to implement, those skilled in the art can be without prejudice to the application intension the case where
Under do similar popularization, therefore the application is not limited by following public specific implementation.
The application provides a kind of light-alloy spinning mold, and Fig. 1 is the structural schematic diagram of the light-alloy spinning mold.
As shown in Figure 1, the application provides a kind of light-alloy spinning mold 1, comprising: upper mold 2 and lower die 3, lock groove 4, top
Glassware 6, the light-alloy spinning mold 1 is used for spinning machine, and spinning roller 5 is provided in the equipment.
Wherein, the upper mold 2 and the cooperation of lower die 3 are for fixing product 7；In the embodiment of the present application, the lower die setting
It is revolution structure on the main shaft of the spinning machine, and based on the light-alloy spinning mold 1, so in the upper mold 2
After fixing the product 7 with lower die 3, the product 7 can make rotary motion, the rotation with the light-alloy spinning mold 1
Wheel 5 is arranged on the spinning machine, when needing to carry out spinning to the product 7, the spinning roller 5 is corresponding be moved to it is described under
The machine-shaping to product 7 is completed in the avris of mould 3, the light-alloy spinning mold 1 and the cooperation of the spinning roller 5.
As stated in the background art, the lower die of general mold can relatively rotate in spinning process with the product, then
It will appear mismachining tolerance；In order to avoid this phenomenon, in the embodiment of the present application, 3 weeks edges of the lower die are provided with for limiting
The lock groove 4 that the product 7 is rotated relative to the lower die 3.
Specifically, as shown in Figure 1, the lock groove 4 is uniformly distributed in the circumferential end surfaces at 3 top of the lower die, and base
To cooperate the processing that could be completed to the product 7 with the spinning roller 5 in the lower die 3, so, the spinning roller 5 can correspond to shifting
It moves to the avris of the lower die 3；The top slot position of the lock groove 4 is higher than the point of penetration of spinning roller 5, corresponding, the lock
Only the bottom end of slot 4 is lower than 5 point of penetration of spinning roller；Further, in order to clearly illustrate the structure of the lock groove 4, please join
Fig. 2 and Fig. 3 are examined, the central axes direction of the lock groove 4 vertically light-alloy spinning mold 1 is set as the locking
The groove depth direction of slot 4；It is corresponding, the central axes direction that the lock groove 4 is parallel to the light-alloy spinning mold 1 is set
For the groove width direction of the lock groove 4, and the longitudinal section in the groove width direction of the lock groove is fan-shaped or up-side down triangle, the lock
Only slot 4 is gradually increased in groove depth depth of the circumferential end surfaces from upper end to lower end edge groove depth direction.The structure of the lock groove 4
Design is advantageous in that in the light-alloy spinning mold 1 rotation, (part is to squeeze to generate for the part of the product 7
Product blank, it is subsequent can turning remove) be pressed into the lock groove 4 by the spinning roller 5, and form male-female engagement, the locking
Slot 4 can accommodate more product blanks, so that the male-female engagement formed is more firm, and then limit the product 7
Relative to the rotation of the lower die 3, it can also make the product part from the lock groove 4 in the process of subsequent demoulding
Directly demould.
Certainly, in order to assist the smoothly demoulding of product 7, ejector 6, the ejector 6 are additionally provided in the lower die 3
It is come into full contact with the lower end of the product 7, so that the ejector 6 can be by the product part in the lock groove 4 with institute
Product 7 is stated to take out of and (demould).
It should be noted that the lock groove 4 in relatively described 5 rotary course of spinning roller of " inlaying " described lower die 3 for squeezing
The product part (product blank) pressed out；It is understood that when the product part is pressed into the locking by the spinning roller 5
It is a part of the product 7 derived from the product part, then after being pressed into the lock groove 4, the two is also when in slot 4
It is structure as a whole, and then the product 7 can be fixed in the lower die 3；After the subsequent product 7 forms, it is only necessary to logical
Cutting tool are crossed to be turned the protrusion part (the product part of the lock groove 4 " inlaying ") on molded article.
In a preferred embodiment of the present application, the quantity of the lock groove 4 is two；The product 7 can be prevented in this way
It, can also be in the case where the setting a small amount of lock groove 4, so that the light-alloy revolves relative to the rotation of the lower die 3
The structure of compression mould 1 is relatively easy, facilitates operation.Certainly, the quantity of the lock groove 4 can also be for one or more than two
A, specific quantity can be set according to actual needs, as long as the product 7 can be limited relative to the lower die 3
It relatively rotates, is the embodiment of the present application scope of the claimed.
In order to preferably explain light-alloy spinning mold described herein is illustrated, explained below by specific application scenarios
State the working principle of the light-alloy spinning mold.
The light-alloy spinning mold 1 is used for the rotary press modelling at light alloy wheel (such as magnesium, aluminium material) wheel rim position.Specifically
, the product is placed in the lower die 3 of the light-alloy spinning mold 1, then, the light-alloy spinning mold 1 it is upper
Mould 2 moves down, and cooperates the lower die 3 to squeeze the product 7 and fix；Then, start the spinning machine, the spinning
Machine spindle drives the light-alloy spinning mold 1 to rotate, the spinning roller 5 under the control of the spinning machine with the product
7 come into contact with, and under (opposite) extruding of rotation of the spinning roller 5, the part of the product can be pressed into lock groove 4, after
And form firm male-female engagement；After running the regular hour, wheel rim position of the light-alloy spinning mold 1 to aluminum vehicle wheel
Rotary press modelling complete the process, the light-alloy spinning mold 1 stops circular-rotation；At this moment, the ejector 6 start gradually to
Upper operation, and the molding product is slowly ejected into the light-alloy spinning mold 1, it then takes out of in the lock groove 4
Product part；Finally the extra product part is removed by manufacturing procedures such as turning, to complete the wheel to aluminum vehicle wheel
The processing at rim position (product molding).
In the process, the product part that the spinning roller 5 squeezes can be accommodated based on the lock groove 4, then
In the light-alloy spinning mold 1 rotation, the product 7 forms male-female engagement with the lock groove 4, thus limiting wheel
Product relatively rotates with mold in spinning process, and then improves the circularity of rim for automobile wheel in spinning process, improves product
Yield rate.
Although the application is disclosed as above with preferred embodiment, it is not for limiting the application, any this field skill
Art personnel are not departing from spirit and scope, can make possible variation and modification, therefore the guarantor of the application
Shield range should be subject to the range that the claim of this application defined.
