Abstract
The invention belongs to the technical field of accessories of mold core molding machine, and provides a horizontal moving mechanism of a core shooting trolley. The horizontal moving mechanism of the core shooting trolley is used for pushing the core shooter mold trolley to move horizontally and comprises a linear rail and a power mechanism, wherein linear rail sliders in rolling fit with the linear rail are mounted at the bottom of the core shooter mold trolley, the power mechanism comprises a servo motor and a screw rod connected with an output shaft of the servo motor, and a nut of the screw rod is fixedly connected with the core shooter mold trolley. A traditional hard rail adopts sliding friction, the friction force is larger, while according to the scheme, the linear rail is adopted as a moving track, rolling friction is adopted between the linear rail and the linear rail sliders, and the friction force is smaller. A positioning mechanism is not required to be arranged according to the scheme, various conditions caused by oil leakage and unstable air pressure are avoided, and safety and environment protection are achieved.
Description
Technical field
The invention belongs to the attachment technique field of the moulding machine of core.
Background technology
Core needs below core shooter mould trolley to the nozzle of core shooter when manufacturing, and carries out penetrating sand so that nozzle moves down and aims at mould openings.Existing mould trolley travel mechanism mainly coordinates with hard rail, utilizes cylinder or hydraulic cylinder dolly to be pushed to the mechanism of assigned address.
The shortcoming of technique scheme is: all need the positioner arranging separately moving-limiting mechanism shift position, and the volume of whole like this travel mechanism can be larger.On the other hand, utilize cylinder to promote dolly and move, its speed can change and changing of producing in load, causes resetting, inefficiency when cylinder air pressure is unstable; And adopt Hydraulic Cylinder dolly to move can to avoid above problem very well, but hydraulic system cost is high, and the leakage problem of hydraulic oil is also difficult to avoid, and can cause certain pollution to the working environment of surrounding, there is certain potential safety hazard.
Summary of the invention
The invention is intended to provide without the need to separately establishing positioner, safety and environmental protection and the core shooting dolly horizontal mobile mechanism of accurately movement can be realized.
Object of the present invention can be reached by following measures: core shooting dolly horizontal mobile mechanism, move for promoting core shooter mould trolley, comprise line rail and actuating unit, the bottom of core shooter mould trolley is provided with and line rail rolling line of engagement rail slide block, and the leading screw that actuating unit comprises servomotor and is connected with servo motor output shaft, the nut of this leading screw is fixedly connected with core shooter mould trolley.
Technique scheme difference with the prior art is: traditional hard rail is then sliding friction, and its frictional force is comparatively large, and this programme adopts line rail as the track of movement, and be rolling friction between line rail and line rail slide block, its frictional force is less.In addition, servomotor is connected with leading screw, the nut of leading screw is due to the connection of core shooter mould trolley, because servomotor drives the bolt rotary of leading screw, now the nut of leading screw then promotes the online rail slip of core shooter mould trolley, because the output accuracy of servomotor is high, therefore the shift position of core shooter mould trolley can more accurately be controlled, compare traditional oil cylinder or cylinder as power source, this programme is without the need to separately establishing detent mechanism, and occur without the various situations that leakage of oil or air pressure shakiness cause, safety and environmental protection.
Further, the line rail slide block at described core shooter mould trolley two ends is provided with sand-aerating apparatus, the core sand dropped on online rail is blown away, prevent line rail from breaking down.
Further, the nut of described leading screw is connected by gusset piece with between core shooter dolly, connects more firm.
Further, with the riser portion of the nut-welding of leading screw, the mode of welding makes the nut of leading screw firmly be connected with connection part, and for the ease of the dismounting of gusset piece, the lateral piece that the lateral piece of gusset piece is threaded with core shooter dolly.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of core shooting dolly horizontal mobile mechanism embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: 1-line rail; 2-line rail slide block; 3-screw rod; 4-nut; 5-gusset piece; 6-mini-fan; 7-core shooter mould trolley.
Embodiment is substantially as shown in Figure 1: core shooting dolly horizontal mobile mechanism, is positioned at the below of core shooter nozzle.This horizontal mobile mechanism comprises linear guides (and line rail 1), this line rail 1 two ends to be threaded postive stop baffle, the rail level of line rail 1 is with wired rail slide block 2, the inner side of this line rail slide block 2 with ball, to realize coordinating with the rolling of line rail 1.Line rail slide block 2 is threaded with core shooter mould trolley 7, and line rail 1 slides to move then to drive on the online rail 1 of core shooter mould trolley 7 and moves.
In order to accurately control the shift position of core shooter mould trolley 7, this core shooter mould trolley 7 is connected with a ball-screw, the screw rod 3 of this ball-screw is connected by shaft coupling with the output shaft of servomotor, and the output shaft of servomotor rotarily drives screw rod 3 and rotates.Between the nut 4 of ball-screw and core shooting mould trolley, gusset piece 5 is installed, this gusset piece 5 comprises the lateral piece be threaded with core shooter dolly, and the riser portion of to weld with the nut 4 of leading screw, when the screw rod 3 of ball-screw rotates, nut 4 can move horizontally on screw rod 3, the core shooter mould trolley 7 be connected with nut 4 also online rail 1 slides thereupon, like this, just accurately can be controlled the shift position of core shooter mould trolley 7 by servomotor.
In addition, in order to prevent core sand from dropping on line rail 1, the use of effect string rail 1, with mini-fan 6 on the line rail slide block 2 of core shooter mould trolley 7 both sides, its covering of the fan alignment line rail 1 rail level.
above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
