Summary of the invention
It is an object of the invention to provide the once through moulding technology of the little miniature single-lug stepless clamp that a kind of production efficiency is high, cost is low, this molding can be automatically performed the little miniature single-lug stepless clamp that the machining accuracy being not less than 60 is high for one minute。
For reaching above-mentioned purpose, the once through moulding technology of a kind of little miniature single-lug stepless clamp of the present invention, comprise the steps:
After the fixed position of shaped device delivered to by moulding material by A by charging aperture, after the mold forming of lower-left, go to movable core；
B will go to movable core by left mould molding after A one-step forming, then by through upper left the first mold forming to movable core；
Left mould after B one-step forming, upper left the first mould are retreated by C simultaneously, and activity core is return in fixing plate, enable shearing assembly and start to shear, and counterdie first rises to charging aperture, and dynamic the shearing after assembly completes shearing of upper right modular belt is return；Upper mould starts to press to counterdie and completes the U-shaped molding of little miniature single-lug stepless clamp, and molding rear right counterdie has risen top, the limit circular arc molding of little miniature single-lug stepless clamp, and upper right mould has declined bottom, the limit circular arc molding of little miniature single-lug stepless clamp；After bottom right mould, upper right mould are return, upper mould is return；Counterdie rises to fixing core successively, upper mould drops to fixing core, upper left the second mould drops to fixing core, and material returned masthead has gone out riveted joint；All moulds are all return, and material returned masthead has gone out the material returned。
The described shaped device in step A includes fixing plate and the fixing core being located on fixing plate, the side of fixing core is provided with movable core, that fixes core is respectively arranged with upper die and lower die up and down, the left side of fixing core is provided with left mould, the right of counterdie is provided with bottom right mould and upper right mould, and the left side of counterdie is disposed with lower-left mould, upper left the first mould, upper left the second mould；Described fixing core is additionally provided with material returned bar and shears assembly。
Described lower-left mould becomes 30 ° of angles with the axle vertical direction of fixing core。
Described bottom right mould becomes 30 ° of angles with the axle vertical direction of fixing core。
Described upper right mould becomes 30 ° of angles with the axle vertical direction of fixing core。
Described material returned bar is provided with two。
After adopting technique scheme, owing to each mould is all by gear synchronous transmission, respective stroke and time is controlled again by the cam each matched, form a non-interference synergic agent, one gas synthesis, completes the precise forming of little miniature single-lug stepless clamp, thus meeting the demand of high-volume professional production, it is greatly improved production efficiency, reduces production cost。
Accompanying drawing explanation
Fig. 1 is the shaped device structural representation in the once through moulding technology of a kind of little miniature single-lug stepless clamp of the present invention。
Detailed description of the invention
Below in conjunction with accompanying drawing, the once through moulding technology of a kind of little miniature single-lug stepless clamp of the present invention is described further；
The once through moulding technology concrete steps of a kind of little miniature single-lug stepless clamp of the present invention have: after moulding material is delivered to the fixed position of shaped device by charging aperture 13, go to movable core 3 after lower-left mould 9 molding；Movable core 3 is gone to by left mould 8 molding after molding, then by through upper left the first mould 10 molding to movable core 3；Left mould 8, upper left the first mould 10 after molding retreat simultaneously, and activity core 3 is return in fixing plate 1, enable shearing assembly 12 and start to shear, and counterdie 5 first rises to charging aperture 13, and upper right mould 7 drives to shear after assembly 12 completes shearing and returns；Upper mould 4 starts to press to counterdie 5 and completes the U-shaped molding of little miniature single-lug stepless clamp, and molding rear right counterdie 6 has risen top, the limit circular arc molding of little miniature single-lug stepless clamp, and upper right mould 7 has declined bottom, the limit circular arc molding of little miniature single-lug stepless clamp；After bottom right mould 6, upper right mould 7 are return, upper mould 4 is return；Counterdie 5 rises to fixing core 2 successively, upper mould 4 drops to fixing core 2, upper left the second mould 10 ' drops to fixing core 2, and material returned bar 11 has ejected riveted joint；All moulds are all return, and material returned bar 11 has ejected the material returned。
Referring to accompanying drawing 1, shaped device in the present invention, it includes fixing plate 1 and the fixing core 2 being located on fixing plate 1, the side of fixing core 2 is provided with movable core 3, that fixes core 2 is respectively arranged with mould 4 and counterdie 5 up and down, the left side of fixing core 2 is provided with left mould 8, and the right of counterdie 5 is provided with bottom right mould 6 and upper right mould 7, and the left side of counterdie 5 is disposed with lower-left mould 9, upper left the first mould 10, upper left the second mould 10 '；Described fixing core 2 is additionally provided with material returned bar 11 and shears assembly 12；Described lower-left mould 9 becomes 30 ° of angles with the axle vertical direction of fixing core 2；Described bottom right mould 6 becomes 30 ° of angles with the axle vertical direction of fixing core 2；Described upper right mould 7 becomes 30 ° of angles with the axle vertical direction of fixing core 2；Described material returned bar 11 is provided with two。
