And the cavity for placing automobile support rod 10 to be formed, which includes the first cavity 14 sequentially connected end to end, second type
Chamber 15 and third cavity 16, the diameter of the second cavity 15 are equal to the diameter of automobile support rod 10, and the diameter of the first cavity 14 is more than
The diameter of second cavity 15, the diameter of third cavity 16 are more than the diameter of the first cavity 14, and die ontology 1 is along the second cavity 15
Diametric(al) is divided into upper mold 11 and lower die 12, and mold core 13 is divided into upper mold core 131 under along the diametric(al) of the second cavity 15
Mold core 132, upper mold 11 are located at the top of lower die 12, and lower die 12 includes pedestal 24 and push rod 34, and one end of push rod 34 is located at first
It is slidably matched in cavity 14 and with the first cavity 14, the other end of actuating unit and push rod 34, which is sequentially connected, is used for driving push rod 34
Length direction along the first cavity 14 reciprocatingly slides, it is preferable that the actuating unit is jumping-up cylinder, and mold core 13 is installed on pedestal 24 simultaneously
It can reciprocatingly slide along the length direction of pedestal 24, correspondence is offered for accommodating automobile support rod respectively in upper mold 11 and lower die 12
10 the first groove 25 and the second groove 26, upper mold 11 and lower die 12 lid close so that the first groove 25 and the second groove 26 lid close with
Automobile support rod 10 is compressed, the first groove 25 and the second groove 26 are equipped with and 16 diameter of third cavity close to one end of mold core 13
The block arc 33 to match.
The detailed process of 10 injection molding of automobile support rod is：Automobile support rod 10 is placed on the first cavity 14, second
In cavity 15, third cavity 16 and the first groove 25, one end of automobile support rod 10 is located in the first cavity 14, under upper mold 11
Pressure, upper mold 11 and lower die 12 press, and the first groove 25 and the second groove 26 cooperatively form for compressing automobile support rod 10
The diameter of four cavities, the 4th cavity is slightly less than the diameter of automobile support rod 10, when upper mold 11 pushes, the interior wall pressure of the 4th cavity
The outer surface of tight automobile support rod 10 is thoroughly locked by automobile support rod 10, and then actuating unit driving push rod 34 is along the first cavity
14 promotion forward, one end of 34 pushing tow automobile support rod 10 of push rod, since automobile support rod 10 is thoroughly locked, automobile support
Bar 10 starts to be plastically deformed under the action of 34 thrust of push rod, the resistance of deformation driving that automobile support rod 10 is generated by plastic deformation
13 forward slip of mold core, the part that automobile support rod 10 is located in the first cavity 14 deform to be formed and 14 diameter of the first cavity
Comparable first pier nose 101, automobile support rod 10 are located at the part in third cavity 16 in resistance of deformation and block arc 33
Under collective effect, is formed and reach specific position with comparable second pier nose 102 of 16 diameter of third cavity, actuating unit driving push rod 34
It postpones, the first pier nose 101 and the second pier nose 102 complete forming process, and last upper mold 11 moves up, and actuating unit driving push rod 34 is moved back
Original position is gone back to, automobile support rod 10 after molding is taken out.
Thereby, by setting the first cavity 14, the second cavity 15 and third there are three different-diameter size in mold core 13
Cavity 16 can disposably form the double pier nose automobile branch for meeting requirement then by 34 pushing tow automobile support rod 10 of push rod
Strut 10, entire forming process is easy to operate, and shaping speed is fast, substantially increases the production effect of double pier nose automobile support rods 10
Rate has been saved production time and production cost, meanwhile, 10 intensity of automobile support rod formed by this mold is high, is using
Do not allow vulnerable in journey, stability is more preferable.
