Specific embodiment
As follows in conjunction with attached drawing 1-8, application scheme is further described:
A kind of clamping of die casting machine injection molding machine comprising foreboard 1(moving template), tailgate 2 and machine cut with scissors toggle component, the machine
Hinge toggle component includes crosshead 3 and the upper hinge assembly 41 for being symmetrically disposed on 3 two sides of crosshead and lower hinge assembly 42, described
Upper hinge assembly 41 and lower hinge assembly 42 respectively include 401, one band andgudgeon 402 of hook hinge and a short hinge 403,1 He of foreboard
It is respectively equipped with the hinge ear 10,20 with machine hinge toggle component cooperation on tailgate 2, is equipped with earhole, institute on the hinge ear 10,20
State hook hinge 401 have the first shaft hole 401a cooperated with the earhole of tailgate 2, the second axis hole 401b being hinged with band andgudgeon 402 with
And the line of third axis hole 401c, the first shaft hole 401a and the second axis hole 401b being hinged with short hinge 403 is relative to the
Included angle A≤20 ° of line between one axis hole 401a and third axis hole 401c, and three axis hole time processings of hook hinge 401 are complete
At, it is ensured that precision；The short hinge 403 has the 4th axis hole 403a with the third axis hole 401c cooperation of hook hinge 401, and with ten
The 5th axis hole 403b that prefix 3 cooperates, the band andgudgeon 402 have the 6th axis hole with the second axis hole 401b cooperation of hook hinge 401
402a, and the 7th axis hole 402b with the earhole cooperation of foreboard 1；When mould-closing stroke terminal, 1 earhole of foreboard and 2 ear of tailgate
The circle center line connecting in hole and included angle B≤5 ° of horizontal plane, linearly, the included angle B is that machine is cut with scissors for the hook hinge 401 and band andgudgeon 402
Beginning angle, the 4th axis hole 403a of the short hinge 403 and the angle C range of the 5th axis hole 403b line and horizontal plane be 80 ° extremely
85 °, form self-locking state.
It is embedding on the foreboard 1 and tailgate 2 to be installed with distribution taxi driver brother woods column 5 symmetrical above and below, it is contemplated that the hinge ear 20 of the tailgate 2
Longitudinal pitch is bigger, and 401 length of hook hinge are also corresponding larger, can get biggish opening stroke, but the changing because of stress point of tailgate 2
Become, deforms also bigger；Vice versa, and 20 longitudinal pitch of hinge ear of tailgate 2 is smaller, deforms also smaller；Therefore the tailgate
The ratio between 2 hinge 20 longitudinal pitch D1 of ear and the longitudinal pitch D2 of brother woods column 5 are 1.1 to 1.3.In view of the foreboard 1
It is bigger to cut with scissors 10 longitudinal pitch of ear, machine hinge initial angle B may be designed to smaller, but the deflection of foreboard 1 can be bigger；Vice versa,
10 longitudinal pitch of hinge ear of foreboard 1 is smaller, deforms also smaller；Therefore the hinge ear of the foreboard 1 indulges 10 to center away from D3 and brother
The ratio between longitudinal pitch D2 of woods column 5 is 1.0 to 1.2.
Hook hinge length L1 is limited to 20 longitudinal pitch of hinge ear of tailgate 2, the length L1 of the hook hinge 2 and band andgudgeon
The ratio between length L2 is 0.65 to 0.82, and the length L1 refers to the distance of center circle of first shaft hole 401a to the second axis hole 401b, described
Length L2 refers to the distance of center circle of the 6th axis hole 402a to the 7th axis hole 402b.
The foreboard 1 is pushed by die cylinder realizes open mold stroke, and machine cuts with scissors each part length and angle of toggle component
After determination, die cylinder stroke determines that die cylinder stroke S is less than the dynamic model row of foreboard 1 by machine hinge toggle component curve movement
Journey reduces the stroke of die cylinder, shortens the open mold time.
Die cylinder pushes machine to cut with scissors toggle component, by hook hinge 401, band andgudgeon 402 and the 403 progress link motion of short hinge to push away
Dynamic foreboard 1(moving template) it is axially moved along brother woods column 5.In molding motion process, 1 movement speed of foreboard is quickly raised to most by zero
Big value, then slows down gradually again, is gradually stretched with the hook hinge 401 of machine hinge toggle component and band andgudgeon 402 to when terminating, closure pressing speed
It is zero, clamping enters self-locking state, and mold clamping force is to amplify the thrust for molding hydraulic cylinder by machine hinge toggle component and formed
's.Therefore, the diameter of die cylinder can be relatively small.In die sinking motion process, foreboard 1 is mobile by going at a slow speed quickly,
Again by quickly turning slowly to zero；The transform linear motion of die cylinder is the rotary motion that machine cuts with scissors toggle component, then cuts with scissors toggle by machine
The rotary motion of component is converted into the linear motion of foreboard 1, and the speed of open mold is cut with scissors the kinetic characteristic of toggle component itself by machine
It influences.
It is that above-mentioned preferred embodiment should be regarded as application scheme embodiment for example, all with application scheme thunder
Same, approximate or technology deduction, replacement, improvement for making based on this etc., are regarded as the protection scope of this patent.
