Abstract
The utility model discloses a core pulling mechanism for a bent tube, which comprises a hydraulic cylinder, a sliding block and a fixed block, wherein the fixed block is fastened with a template; a fixing shaft is arranged on the fixed block; a bearing is arranged on the fixing shaft; a gear is arranged on the outer ring of the bearing; a rack is connected on the hydraulic cylinder, and meshes with the gear; and the sliding block is connected with the hub of the gear. By utilizing the structure provided by the utility model, the core pulling mechanism for the bent tube can be fixed easily andoccupies small space in mould.
Description
Technical field
The utility model relates to a kind of bend pipe core-pulling mechanism in the core-pulling mechanism in a kind of mould of plastics, particularly mould of plastics.
Background technology
In the existing injection forming mold structure, when there is the circular arc back-off in the side of plastic products, particularly hour at bend pipe circular arc degree, then need the slide block rotational angle big, because the slide block rotational angle is bigger, and the core position intermediate is very little, uses common oily purt to drive that mechanism that connecting rod drives the slide block rotation again can't fix and die space is very big.
The utility model content
The purpose of this utility model is for a kind of bend pipe core-pulling mechanism being provided, utilize structure of the present utility model can make the bend pipe core-pulling mechanism be convenient to fix, and the die space that takies being little.
For achieving the above object, a kind of bend pipe core-pulling mechanism comprises oily purt and slide block, also comprises fixed block.Fixed block and mould are fastened, and fixed block is provided with fixed axis, and fixed axis is provided with bearing, and the outer ring of bearing is provided with gear; Be connected with tooth bar on the oil purt, rack and pinion is meshed; Described slide block is connected with the gear wheel hub.
During work, tooth bar moves under the effect of oily purt, the driven gear rotation of tooth bar motion back, because the wheel hub of slide block and gear links together, therefore, the gear driven slide block is with the central axis anglec of rotation of fixed axis, thereby reaches the purpose of loosing core.This bend pipe core-pulling mechanism is fixedly the time, and fixed block is fastened on the template, and fixed axis is fixed on the fixed block, and gear is connected with fixed axis by bearing, slide block directly is connected with the wheel hub of gear, therefore, and convenient fixing, and simple in structure, like this, the die space that takies is little.
As improvement, be provided with slider guide between described fixed block and template, gear is provided with guide runner.Adopt this structure, the guide runner of gear moves along slider guide, like this, can make the motion of gear accurate.
As improvement, described template is provided with the press strip with guide runner motion.Adopt this structure, slide block moves along press strip, plays the effect of guide-localization, makes slide block movement accurate, is difficult for scratching goods during slide block movement.
As improvement, be provided with contiguous block between described tooth bar and the oily purt.Be convenient to the installation of tooth bar and oily purt like this.
Description of drawings
Fig. 1 is a vertical view of the present utility model;
Fig. 2 is a three-dimensional view of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in more detail
Bend pipe core-pulling mechanism as depicted in figs. 1 and 2 is made of fixed block 1, fixed axis 2, bearing 3, gear 4, oily purt 5, tooth bar 6, contiguous block 7, press strip 8, core 10, slide block 11, template 12 and slider guide 9; Fixed block 1 is installed on the template; Fixed axis 2 is fixed on the fixed block 1; Bearing 3 is enclosed within on the bottom of fixed axis 2; Gear 4 is installed on the outer ring of bearing 3; Oil purt 5 is contained in outside the mould, and tooth bar 6 is meshed with gear 4, and tooth bar 6 is connected with oily purt 5 by contiguous block 7, and so oily purt 5 is convenient to and being connected of tooth bar 6; Slide block 11 is connected with the wheel hub of gear 4; Have guide runner 41 on the wheel hub of described gear 4, slider guide 9 is installed in 12 of fixed block 1 and templates, and passes the guide runner 41 in the gear 4, and the guide runner 41 in the gear 4 can move along slider guide 9, like this kinematic accuracy height of gear 4; Described core 10 is installed on the template 12; Press strip 8 is installed on the template 12, and slide block 11 can move along press strip, can improve the kinematic accuracy of slide block 11 like this, is difficult for scratching goods during slide block 11 motions.
During work, tooth bar 6 moves under the effect of oily purt 5, tooth bar 6 motion back driven gear 4 rotations, because the wheel hub of slide block 11 and gear 4 links together, therefore, gear 4 drives the central axis anglec of rotation of slide block 11 with fixed axis 2, thereby reaches the purpose of loosing core.This bend pipe core-pulling mechanism is fixedly the time, and fixed block 1 is fastened on the template 12, and fixed axis 2 is fixed on the fixed block 1, gear 4 is connected with fixed axis 2 by bearing 3, and slide block 11 directly is connected with the wheel hub of gear 4, therefore, convenient fixing, and simple in structure, the die space that takies is little.
