Description
Technical field
The utility model belongs to plastic mould field, relates in particular to the mould that a kind of parabolic inner threaded member is used bearing-transmission to drive plastic parts to eject.
Background technology
The bearing transmission mechanism of mould is in Design of Dies, for plastic parts inside, to have the mechanism of parabolic screw thread, also can be used for external screw-thread.
Traditional internal whorl plastic parts is used the mechanisms such as oil cylinder, chain, gear to make the plastic parts demoulding.Motion mode is that chain connects the motion gear on main shaft for oil cylinder, and the gear of main motion gear and each plastic parts is tangent reaches motion, makes the plastic parts demoulding.This kind of structure mold complexity, and chain easily goes wrong at the volley.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind ofly to be utilized plastic parts to drive screw thread rotation axle to rotatablely move in bearing to reach the demoulding, simple in structure, mould structure is stable, can improve mould production efficiency, improve die quality, the bearing-transmission that increases mould physical life drives the mechanism of the plastic parts demoulding.
The utility model is achieved through the following technical solutions: a kind of bearing-transmission drives the mechanism of the plastic parts demoulding, comprise front mould mold insert, A plate, push pedal, supporting plate, B plate, screw thread rotation axle, concentric axle sleeve, bearing, back-up block, rear mold mold insert, pull bar, thread bush and plastic parts, described push pedal is arranged on A plate lower end, described front mould mold insert is arranged in the middle of A plate, described rear mold mold insert is arranged in the middle of push pedal, described supporting plate is arranged on push pedal lower end, described concentric shafts is set on supporting plate inside, described screw thread rotation axle is arranged in concentric axle sleeve, described screw thread rotation axle is provided with thread bush outward, described B plate is arranged on supporting plate lower end, described bearing is arranged on screw thread rotation axle lower end, described back-up block is arranged on bearing lower end, described plastic parts is sleeved on screw thread rotation axle upper end.
As preferred technical scheme, in described front mould mold insert and rear mold mold insert, cooling system is installed.
As preferred technical scheme, the bearing of described screw thread rotation axle lower end is provided with two, is up and down and distributes.
The beneficial effects of the utility model are: the utility model can reduce the complexity of oil cylinder, chain and gear transmission structure, thereby reduce mould structure and mould production cost, and the utility model Stability Analysis of Structures, increases production efficiency and improve die quality in addition.
Accompanying drawing explanation
For ease of explanation, the utility model is described in detail by following specific embodiment and accompanying drawing.
Fig. 1 is matched moulds state diagram of the present utility model;
Fig. 2 is the state diagram that ejects of the present utility model;
Fig. 3 is local rotating shaft motion diagram.
The specific embodiment
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of bearing-transmission of the present utility model drives the mechanism of the plastic parts demoulding, comprise front mould mold insert 1, A plate 2, push pedal 3, supporting plate 4, B plate 5, screw thread rotation axle 7, concentric axle sleeve 8, bearing 9, back-up block 11, rear mold mold insert 12, screw thread rotation axle 7, pull bar 14, thread bush 15 and plastic parts 16, described push pedal 3 is arranged on A plate 2 lower ends, described front mould mold insert 1 is arranged in the middle of A plate 2, described rear mold mold insert 12 is arranged in the middle of push pedal 3, described supporting plate 4 is arranged on push pedal 3 lower ends, described concentric axle sleeve 8 is arranged on supporting plate 4 inside, described screw thread rotation axle 7 is arranged in concentric axle sleeve 8, the outer thread bush 15 that is provided with of described screw thread rotation axle 7, described B plate 5 is arranged on supporting plate 4 lower ends, described bearing 9 is arranged on screw thread rotation axle 7 lower ends, described back-up block 11 is arranged on bearing 9 lower ends, described plastic parts 16 is sleeved on screw thread rotation axle 7 upper ends.
As preferred technical scheme, in described front mould mold insert 1 and rear mold mold insert 12, cooling system is installed, mold temperature assurance is consistent aborning to guarantee plastic parts.
As preferred technical scheme, the bearing 9 of described screw thread rotation axle 7 lower ends is provided with two, is up and down and distributes.
Wherein, for assurance screw thread rotation axle 7, do Concentric rotation motion, in structure, have thread bush 15, concentric axle sleeve 8 and bearing 9.
Rear mold motion principle: front mould pull bar 14 drives push pedal 3 supporting plates 4 to open rear mold, push pedal pulls plastic parts 16, plastic parts 16 internal threads drive screw thread rotation axle 7 to rotate with bearing at concentric axle sleeve 8 thread bush 15, thereby it is separated from screw thread rotation axle to reach plastic parts 16, complete the whole cycle of plastic parts 16 in mould is produced.
The beneficial effects of the utility model are: the utility model can reduce the complexity of oil cylinder, chain and gear transmission structure, thereby reduce mould structure and mould production cost, and the utility model Stability Analysis of Structures, increases production efficiency and improve die quality in addition.
The above, be only the specific embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
