Abstract

The utility model relates to a removable flask molding structure with convenience in core setting and high efficiency in molding. A rotating shaft is vertically and fixedly mounted on the side edge of a rack in a direction of an upper sand box bracket and a lower sand box bracket and is driven by a template rotating oil cylinder at the lower end through a crank; a template bracket is horizontally and fixedly mounted at the top end of the rotating shaft and swings and rotates when the rotating shaft rotates; a rotating sleeve is coaxially sleeved on the rotating shaft; a rotating swinging rack is fixedly mounted at the middle part of the rotating sleeve and is driven to swing and rotate by a reducing motor mounted at the lower part of the rotating sleeve; two lower sand boxes are symmetrically placed at the both ends of the rotating swinging rack; and swinging and rotating tracks of the lower sand boxes are formed above the lower sand box bracket. According to the removable flask molding structure provided by the utility model, the actions of core setting and box closing can be carried out simultaneously by adding one lower sand box and a rotating rack, so that the core setting operation is convenient to realize, the molding time is saved, and the molding efficiency is improved. Meanwhile, the core setting operation of an operator is more convenient and safer by unscrewing the lower sand boxes.

Description

The removable flask moulding structure of core, efficient moulding under a kind of convenience

Technical field

The utility model belongs to casting field, relates to moulding machine, the removable flask moulding structure of core, efficient moulding under especially a kind of convenience.

Background technology

Moulding machine is the core equipment of casting field, and the moulding speed of moulding machine directly has influence on the production efficiency of Foundry Works, and whether following core makes things convenient for is again the significant consideration that moulding machine is selected by manufacturer.Generally moulding machine adopts paired sandbox, and this version can't be carried out core and mould assembling action simultaneously, has wasted the time, has reduced moulding efficient.

Summary of the invention

The purpose of the utility model is to overcome the weak point of prior art, and the removable flask moulding structure of core under a kind of convenience that a kind of moulding time is short, moulding efficient is high, efficient moulding is provided.

The utility model solves its technical problem and takes following technical scheme to realize:

The removable flask moulding structure of core, efficient moulding under a kind of convenience; Comprise frame, cope, drag box carriage, rotation rocker, rotating shaft, rotary sleeve, reducing motor, template, falsework and template rotary oil cylinder; Be coaxially installed with linear bearing in the frame, at the upper and lower interval of this linear bearing guide pin bushing be installed, level is fixed with cope carriage and drag box carriage respectively on these two guide pin bushings; Cope carriage and drag box carriage be coaxial upper and lower displacement on frame; Frame side in cope carriage and drag box carrier direction vertically is fixed with rotating shaft, and through the driving of cranking arm, level installs falsework to this rotating shaft on the top of rotating shaft by the template rotary oil cylinder of lower end; Falsework rotation thereupon when rotating shaft rotates; Rotating shaft coaxle is with rotary sleeve outward, is fixed with the rotation rocker at the middle part of rotary sleeve, and this rotation rocker drives rotation by the reducing motor that is installed in the rotary sleeve bottom; Symmetry is put two drag boxs is arranged at the two ends of rotation rocker, and the rotation track of drag box is above the drag box carriage.

And, a template is installed near switch on the frame of corresponding templates bracket locations, a sandbox is installed near switch on the drag box carriage.

The advantage and the beneficial effect of the utility model are:

The utility model has only increased a drag box and rotary frame and has just guaranteed that time core and mould assembling action carry out simultaneously; Promptly made things convenient for time core to save the moulding time again; Improved moulding efficient, simultaneously because the back-out of drag box makes core more convenient operation under the operator, safety.

Fig. 2 is the vertical view (falsework and rotary bracket part) of Fig. 1;

Fig. 3 is the partial left side view of Fig. 2.

The specific embodiment

Below in conjunction with accompanying drawing and through specific embodiment the utility model is done further to detail, following examples are descriptive, are not determinate, can not limit the protection domain of the utility model with this.

The removable flask moulding structure of core, efficient moulding under a kind of convenience; Comprise frame 9, cope 6, drag box carriage 13, rotation rocker 2, rotating shaft 15, rotary sleeve 14, reducing motor 17, falsework 3 and template rotary oil cylinder 16; Be coaxially installed with linear bearing 8 in the frame; Upper and lower interval at this linear bearing is equipped with guide pin bushing 7; Level is fixed with cope carriage 5 and drag box carriage respectively on these two guide pin bushings, and cope carriage and drag box carriage be coaxial upper and lower displacement on frame.Frame side in cope carriage and drag box carrier direction vertically is fixed with rotating shaft; This rotating shaft 18 is driven through cranking arm by the template rotary oil cylinder of lower end; Level installs falsework on the top of rotating shaft; Template 4 is put in falsework rotation thereupon when rotating shaft rotates on falsework; Rotating shaft coaxle is with rotary sleeve outward; Be fixed with the rotation rocker at the middle part of rotary sleeve; This rotation rocker drives rotation by the reducing motor that is installed in the rotary sleeve bottom, and symmetry is put two

drag boxs

1 and 11 are arranged at the two ends of rotation rocker, and the rotation track of drag box is above the drag box carriage.

Rotation position for accurate perception pattern carrier and drag box is equipped with a template near switch 10 on the frame of corresponding templates bracket locations, a sandbox is installed near switch 12 on the drag box carriage.

The operation principle of the utility model is:

First drag box (left side) position is the core setter position; The operator is placed on core in first drag box; Reducing motor driven in rotation axle Rotate 180 °, the first drag box Rotate 180 ° (being abutted against nearly switch location) be to second drag box (right side) position, through linear bearing make cope carriage and drag box carriage in opposite directions displacement carry out the mould assembling action; Second drag box moves to the first drag box position and plays core simultaneously; Play core and mould assembling action to carry out simultaneously like this, saved the time, improved moulding efficient.

When last drag box mould assembling, die holder is through template rotary oil cylinder pendulum, and 90 spend side, like Fig. 2, realizes disclosing case thus.
