Abstract
The utility model relates to the technical field of machinery, in particular to a casting machine top mould core-pulling mechanism with an inverted oil cylinder, which comprises an upper beam, a lower beam, guide posts, an oil cylinder body, a piston rod, a top mould beam and a top mould. The core-pulling mechanism is characterized in that the middle of the upper beam is sequentially connected with the piston rod, the oil cylinder body, the lower beam and the top mould beam from top to bottom, the left end and the right end of the upper beam are connected with the top ends of the two guide posts respectively, the bottom ends of the two guide posts are connected with the left end and the right end of the top mould beam respectively, the top mould is arranged at the bottom of the top mould beam, and the left end and the right end of the lower beam are connected with the insides close to the bottoms of the two guide posts respectively. Compared with the prior art, the core-pulling mechanism has the advantages that the oil cylinder is inverted, the piston rod of the oil cylinder is separated from the top mould beam so that heat transfer is avoided, the oil cylinder body on the lower portion of the oil cylinder is fixed onto the lower beam, the piston rod on the upper portion of the oil cylinder is fixed to the guide posts through the upper beam, the structure is more stable, and core-pulling stability is ensured.
Description
Technical field
The utility model relates to field of mechanical technique, specifically a kind of casting machine backform core-pulling mechanism of being inverted oil cylinder that adopts.
Background technology
Piston mould needs the backform core-pulling mechanism in the die sinking process, adopt hydraulic jack to drive the backform crossbeam and realize moving up and down.At present, oil cylinder in the backform core-pulling mechanism adopts and is just putting mode, and referring to Fig. 1, promptly piston rod directly connects the backform crossbeam, in process of production, heat can be delivered on the piston rod by backform and backform crossbeam, causes temperature drift, thereby influences the quick aging of hydraulic jack seal, oil leakage phenomenon appears, and the oil cylinder in this mechanism has only its lower end to fix, and the upper end of oil cylinder is unsettled, is not very stable on the structure.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, the oil cylinder in the backform core-pulling mechanism is inverted, and a kind of backform core-pulling mechanism of design.
For achieving the above object, design a kind of casting machine backform core-pulling mechanism of being inverted oil cylinder that adopts, comprise entablature, sill, lead, oil cylinder body, piston rod, backform crossbeam, backform, it is characterized in that: connect piston rod, oil cylinder body, sill middle part in the middle of the entablature from top to bottom successively; Two ends, the entablature left and right sides connect the top of two leads respectively, and the bottom of two leads connects the two ends, the left and right sides of backform crossbeam respectively, and backform is established in the bottom of backform crossbeam, and the two ends, the left and right sides of sill connect two nearly bottom inside of lead respectively.
Described backform is provided with two at least.
The utility model is compared with prior art, and oil cylinder is inverted, and the piston rod of oil cylinder is separated with the backform crossbeam, avoids heat transmission; And the oil cylinder body of oil cylinder bottom is fixed on the sill, and the piston rod on oil cylinder top is also fixed by entablature and lead, and structure is more stable, guarantees to loose core steadily.
Description of drawings
Fig. 1 is the structural representation of original casting machine backform core-pulling mechanism.
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
Now the utility model is further described in conjunction with the accompanying drawings.
The middle part that connects piston rod 4, oil cylinder body 3, sill 7 in the middle of the entablature 1 from top to bottom successively; Two ends, entablature 1 left and right sides connect the top of two leads 2 respectively, the bottom of two leads 2 connects the two ends, the left and right sides of backform crossbeam 5 respectively, at least two backforms 6 are established in the bottom of backform crossbeam 5, and the two ends, the left and right sides of sill 7 connect two leads, 2 nearly bottom inside positions respectively.
In the utility model, adopt the oil cylinder inverted design, the piston rod 2 of oil cylinder drives entablature 1 motion, two leads 3 of entablature 1 drive are done and are pumped, two leads connect backform crossbeam 5 to be realized moving up and down, so just avoided heat to be delivered on the piston rod 2, prolonged the service life of cylinder seal spare greatly, also make simultaneously loose core more steady.
