Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in the figure, operation principle during parting of the present invention: after injection mo(u)lding completes, cope match-plate pattern is thrown off in die cavity, projection due to lower bolster right side wall is also inserted in moulding sidewall, so, moulding can not be followed cope match-plate pattern and together be departed from die cavity, and namely the projection of template right side wall can play spacing effect;
In point mold process, if adopt more energy-conservation drive unit, namely the first magnet assemblies is comprised, during the drive unit of the parts such as the second magnet assemblies, driven by motor rotating shaft is rotated along a direction all the time, when being arranged on that in the second magnet assemblies in rotating shaft, the first arc-shaped magnet turns to the region that bar magnet is just right, because the S pole of the first arc-shaped magnet and the S of bar magnet bottom repel extremely mutually, thus bar magnet and shell can be driven to move up, namely rotated clockwise to make travelling gear by the engaged transmission of the first linear gear rack and travelling gear, fork also correspondingly rotates counterclockwise, fork upper end turns left, in the process that fork upper end turns left, can by the first straight pin and the first open slot coordinate drive the second linear gear rack to be moved to the left, the second linear gear rack is moved right to drive side template by the transmission of the first gear and the 3rd linear gear rack, simultaneously, second linear gear rack left part can push cross bar and lower bolster moves along guide pin bushing axis left, the lower bolster be moved to the left can drive projection to extract from moulding sidewall, and stage clip can be pressed in spring base for lower bolster counter motion energy reserve by the cross bar left part be moved to the left, that is, lower bolster is contrary with the direction of motion of side template, namely mutual away from, thus moulding just can take out by operating personnel in mould, in a word, lower bolster and side template mutually away from process in, moulding also can relative to side template inwall generation relative displacement, and the installing hole on moulding can relative to projection outer wall generation relative displacement,
When the second arc-shaped magnet in the second magnet assemblies and bar magnet just pair time, because the N pole of the second arc-shaped magnet and the S pole of bar magnet bottom attract each other, thus bar magnet and shell can be driven to move down, and then drive other parts counter motions successively, and stage clip pushes cross bar and lower bolster is oppositely mobile to draw close to side template, until matched moulds completes.Because the second arc-shaped magnet takies same 3/4ths girths circumferentially, that is, rotating shaft drives the second magnet assemblies to rotate in the turnaround time, 1/4th times be the first arc-shaped magnet and bar magnet just to for parting, 3/4ths times were that the second arc-shaped magnet and bar magnet are just to for matched moulds.So the injection time after matched moulds of the present invention is three times for workman's pickup time after parting, so both can ensure the time required for matched moulds, after can giving parting again, pickup provides time enough, improves the operating efficiency of automatic die assembly injection moulding and parting pickup.
