Drawings
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this application, illustrating embodiments of the invention and description thereof for the purpose of explanation and are not intended to constitute an undue limitation on the invention. In the drawings:
fig. 1 is a schematic top view of a quick-change core-pulling device according to an embodiment;
FIG. 2 isbase:Sub>A schematic view of the structure of FIG. 1 along the line A-A;
fig. 3 is a schematic structural diagram of a mold with a quick-change core-pulling device.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 and 2, the quick-change core pulling device includes a core pulling mounting base 1 disposed on a mold, a core pulling mechanism 2 detachably connected to the core pulling mounting base 1, at least one cylinder 3 connected to the core pulling mounting base 1, and a lock pin 4 connected to a piston rod of the cylinder 3; the core-pulling mounting seat 1 is provided with a first direction hole 5 and a second direction hole 6 which are communicated; the core-pulling mechanism 2 is provided with a lock sleeve 7 inserted into the first direction hole 5; the lock pin 4 can slide in the second direction hole 6; the lock sleeve 7 is provided with a pin hole matched with the lock pin 4.
The working principle is as follows: as shown in fig. 3, a core member 2 or a second core member 10 capable of being quickly replaced is provided on the base mold to meet the demand for producing various products. Referring to fig. 1 and 2, when the core pulling piece 2 or the second core pulling piece 10 needs to be replaced, the piston rod of the air cylinder 3 is controlled to contract, so that the lock pin 4 is pulled out from the lock sleeve 7, the core pulling mechanism 2 or the second core pulling piece 10 can be separated from the core pulling mounting seat 1, after the core pulling mechanism 2 or the second core pulling piece 10 is taken down, the second core pulling piece 10 or the core pulling mechanism 2 is inserted, the piston rod of the air cylinder 3 is controlled to extend, so that the lock pin 4 is inserted into the lock sleeve 7, and the second core pulling piece 10 or the core pulling mechanism 2 is fixed.
Optionally, one of them embodiment, the utility model provides a quick change device of loosing core on the basis of preceding scheme, still has both ends respectively with the cylinder fixed plate 8 of loosing core mount pad 1 and cylinder 3 and being connected.
Optionally, in one embodiment, the quick-change core pulling device provided by the present invention further includes, on the basis of the foregoing scheme, a guide sleeve 9 connected to an inner wall of the second directional hole 6; the lock pin 4 is connected with the guide sleeve 9 in a sliding way.
Optionally, in one embodiment, the utility model provides a quick-change core pulling device, on the basis of the foregoing scheme, an inverted cone-shaped guide opening is provided at an entrance of the pin hole of the lock sleeve 7; the end of the locking pin 4 remote from the cylinder 3 has a conical guide section. The entrance of pinhole is equipped with the back taper guide way mouth and lockpin 4 keeps away from 3 ends of cylinder and is equipped with the toper direction section, and in the change process, makes lockpin 4 insert more easily, is convenient for correct the position of mechanism of loosing core.
The present invention is not limited to the above preferred embodiments, and various changes and modifications can be made within the spirit of the present invention defined in the claims and the description, so that the same technical problems can be solved and the intended technical effects can be obtained, which are not repeated. All solutions which can be directly or conceivably obtained by a person skilled in the art from the disclosure of the present invention also belong to the scope of protection of the present invention, as long as they are within the spirit of the present invention as defined by the appended claims.
