Abstract
The utility model relates to a core-pulling mechanism of liner forming molds of doors; the core-puling mechanism is characterized in that: a driving guide shaft is arranged along the direction which is vertical to the core-pulling and demoulding moving direction of core-pulling blocks; one end of a connecting pole is articulated with the driving guide shaft, and the other end is articulated with the inner end of a guiding column; a core-pulling fixing plate which is provided with the core-pulling blocks is connected at the outer end of the guiding column; the guiding column is limited along the core-pulling and demoulding moving direction of the core-pulling blocks by two linear bearings. An air cylinder is arranged at the position of an axle center of a guiding shaft; torque moment which causes friction self-locking can not be generated when the guiding shaft moves with a guiding sleeve relatively; the space between the two linear bearings is large as much as possible, even if the abrasion is severe between the guiding column and the linear bearings, the accuracy of the position of the core-pulling blocks can not be effected, thus improving the quality of the liner of refrigerator door.
Description
Technical field
The utility model relates to an inner bag mould, on the body formed mould of more particularly a kind of application door, makes the mould core-pulling mechanism of the demoulding smoothly.
Background technology
Fruit and vegetable box generally all is installed on the refrigerator doors, and the square groove on the fruit and vegetable box is inserted on the refrigerator doors inner bag side boss, and fruit and vegetable box should be placed proper, does not rock.During door inner bag moulding, need do at the square boss place of mould and to loose core, being convenient to that an inner bag throws off from mould is the demoulding, therefore needs to make core-pulling mechanism on mould.Existing core-pulling mechanism generally is that cylinder promotes push rod, and push rod slides on the copper guide pad, promotes link motion simultaneously, the connecting rod fixed head motion that promotes to loose core, and the piece of loosing core is installed in movement therewith on the fixed head of loosing core, and realizes the demoulding.The fixed head of loosing core also is equipped with linear bearing or guide pin bushing, is inserted with guide pillar in linear bearing or the guide pin bushing, and guide pillar is fixed on the die main body, with control loose core fixed head and the motion of piece of loosing core.Owing to be at high temperature to work, add that action is ordinary, cause each kinematic pair wearing and tearing very fast.It is very fast to wear and tear between push rod and the copper guide pad, and the gap increases gradually, easily produces friction self-locking.Wearing and tearing are very fast between linear bearing or guide pin bushing interpolation and the guide pillar, the gap increases gradually, when the moulding of door inner bag, the suction function that the piece of loosing core is vacuumized, the fixed head of loosing core is easy to generate with the piece of loosing core and rocks, make the position of refrigerator doors inner bag side boss not reach designing requirement, fruit and vegetable box can occur and put and just do not waiting phenomenon.Therefore intrinsic mechanism reliability is relatively poor, and the quality of refrigerator doors inner bag can not get guaranteeing.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, the core-pulling mechanism of a kind of inner bag mould is provided, in the hope of both improving the reliability of mechanism, can improving the quality of refrigerator doors inner bag again.
The utility model technical solution problem adopts following technical scheme:
The utility model door inner bag mould core-pulling mechanism, its design feature are along the demoulding moving direction of loosing core perpendicular to the piece of loosing core the guide shaft that straight line moves to be set, and cylinder is installed in the place, axle center of guide shaft, and cylinder piston rod links to each other with an end of guide shaft; One end and the guide shaft of connecting rod are hinged, the guide pillar that the other end and straight line move inner hinged, and the fixed head of loosing core that the piece of loosing core is installed is connected the outer end of guide pillar, and guide pillar is spacing on the moving direction of the demoulding of loosing core along the piece of loosing core by two linear bearings.
Design feature of the present utility model also is, two linear bearings are respectively near the both ends of guide pillar.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The utility model cylinder is installed in the place, axle center of guide shaft, when guide shaft and guide pin bushing relative motion, can not produce the torsional moment that causes friction self-locking, has improved the reliability of mechanism.Two linear bearings are set on the every guide pillar, and two linear bearing spacings should be tried one's best greatly, even serious wear between guide pillar and the linear bearing can not influence the accuracy of the piece position of loosing core yet, have improved the quality of refrigerator doors inner bag.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model floor map.
Fig. 3 is Fig. 1 side view.
Number in the figure: 1 loose core fixed head, 2 linear bearings, 3 loose core piece, 4 connecting rods, 5 guide pillars, 6 die main bodies, 7 cylinders, 8 guide shafts, 9 guide pin bushings.
Below by the specific embodiment, the utility model is described in further detail in conjunction with the accompanying drawings:
The specific embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, along the demoulding moving direction of loosing core perpendicular to the piece 3 of loosing core straight line is set and moves guide shaft 8, cylinder 7 is installed in the place, axle center of guide shaft 8, and cylinder piston rod links to each other with an end of guide shaft 8; One end and the guide shaft 8 of connecting rod 4 are hinged, the guide pillar 5 that the other end and straight line move inner hinged, and the fixed head 1 of loosing core that the piece 3 of loosing core is installed is connected the outer end of guide pillar 5, and guide pillar 5 is spacing on the moving direction of the demoulding of loosing core along the piece of loosing core by two linear bearings 2.
In concrete the enforcement, cylinder 7 is fixed on the die main body 6, the piston rod of cylinder 7 is connected with an end of guide shaft 8, the other end of guide shaft 8 is slidingly arranged in the guide pin bushing 9, and guide shaft 8 is provided with pin-and-hole, and connecting rod 4 adopts bearing pin hinged with guide shaft 8, connecting rod 4 also adopts bearing pin hinged with guide pillar 5, guide pillar 5 is positioned in two linear bearings 2 that are provided with of being separated by, and what distance should design between two linear bearings 2 is big as far as possible, makes two linear bearings 2 both ends of close guide pillar 5 respectively.
The outer end of guide pillar 5 connects firmly with the fixed head 1 of loosing core, and the fixed head 1 of loosing core is installed the piece 3 of loosing core.
In the course of work, the piston rod movement of cylinder 7 drives guide shaft 8 straight lines and moves, guide shaft 8 pulling connecting rods 4, and connecting rod 4 makes guide pillar 5 move at linear bearing 4 cathetus, and the straight line of guide pillar 5 moves and drives the loose core fixed head 1 and the piece 3 of loosing core, thereby realizes the moulding and the demoulding.
