Description
Technical Field
The invention belongs to the technical field of disassembly auxiliary equipment of a mold with an insert, and particularly relates to a hammering type disassembly tool.
Background
In the mold manufacturing process, the mold needs to be repeatedly debugged to meet the requirement of products. In this process, the mold is often required to be disassembled, and the insert in the mold is removed from the mold because the small end of the insert passes through the mold to expose the surface of the mold, and the small end of the insert is required to be knocked during the disassembly. In the actual disassembly operation, the insert is easily damaged or even scrapped due to the used tools or knocking force, knocking angle and the like. Particularly, when the cylindrical insert is used, casting liquid in the mold can enter a gap between the insert and the mold to block the gap, so that acting force between the insert and the mold is enhanced, the insert is very difficult to disassemble, and the insert is loosened by using a larger hammering force when the insert is initially disassembled, so that the end part of the insert is very easy to seriously damage or bend and deform, and even the insert is directly scrapped.
Disclosure of Invention
The invention aims to provide a hammering type dismounting tool which is used for solving the problem that in the prior art, an insert is easy to damage when the insert is dismounted.
In order to achieve the above purpose, the basic scheme of the invention provides a hammering type dismounting tool, which comprises a movable claw group surrounding a containing cavity, wherein a cover body is movably sleeved on the outer side of the movable claw group, and the inner side of the cover body is matched with the conical surface of the movable claw group.
The principle and beneficial effect of this basic scheme lie in: the accommodating cavity enclosed by the movable claw groups is sleeved on a workpiece to be disassembled, then the movable claw groups are wrapped by the cover body, the movable claw groups are pushed to move by hammering the cover body through conical surface matching, and the cover body can apply extrusion force towards the accommodating cavity to the movable claw groups when pushing the movable claw groups, so that friction force of the movable claw groups to the workpiece is increased, the movable claw groups push the workpiece to move, and disassembly to the workpiece is realized. Thereby avoiding the problem of serious damage or even scrapping of the workpiece caused by hammering and disassembling.
Further, the cover body is connected with a push rod for pushing out the movable claw group in an axial sliding manner. By adopting the arrangement, the movable claw group is conveniently pushed out of the cover body through the ejector rod, so that the movable claw group is conveniently separated from the workpiece after the disassembly is completed.
Further, the ejector rod is connected with the movable claw group. By adopting the arrangement, the movable claw group is not easy to automatically deviate from the cover body under the connection action of the ejector rod, so that the phenomenon that parts scatter around can be avoided.
Further, one end of the ejector rod, which faces the movable claw group, is provided with a ball head part, all movable claws of the movable claw group are provided with grooves matched with the ball head part in shape, and the outer side of the movable claw group is sleeved with an elastic piece. By adopting the arrangement, the grooves on the movable claws are matched with the ball head parts to position all the movable claws conveniently, and the movable claws are kept in contact with the ejector rod through the elastic piece, so that the movable claw group can not be dislocated when moving in the cover body. By adopting the arrangement, all movable claws of the movable claw group can be mutually separated, so that the movable claw group and the ejector rod are conveniently connected and separated, and the movable claw group with the unnecessary containing cavity is conveniently replaced as required.
Further, a gap for the movable claw to swing around the ball head part is arranged between the movable claw and the ejector rod, and the elastic piece is arranged opposite to the gap. By adopting the arrangement, the movable claw can rotate around the ball head part through the gap under the action of the elastic force of the elastic piece, so that the movable claw group can automatically open when moving out of the cover body, the workpiece and the movable claw group are conveniently separated, and meanwhile, when the movable claw group is sleeved on the workpiece, the mutually-open movable claws can enable the space of the accommodating cavity to be larger, so that the movable claw can be conveniently and rapidly operated.
Further, be connected with on the cover body with hold the axial parallel guide bar in chamber, sliding connection has the hammering head on the guide bar. By adopting the arrangement, the hammering head is conveniently utilized to hammer the cover body along the fixed hammering direction, so that the hammering tool is not required to be used singly to hammer the cover body, the hammering operation is convenient, and the problem that the workpiece is easily damaged due to overlarge axial included angle between the hammering direction and the workpiece is avoided.
Further, the guide rod and the ejector rod are integrally formed. By adopting the arrangement, the structure is simplified, the number of parts is reduced, and the processing cost is reduced.
Further, the one end that the guide bar kept away from the cover body is connected with the stopper, be provided with the bellying of radially extending along the guide bar on the stopper, be provided with on the hammering head with bellying separation and reunion complex spout. By adopting the arrangement, the problem that the hammering head is completely separated from the guide rod when in use and carried and inconvenience is brought to the use can be avoided.

Detailed Description
The following is a further detailed description of the embodiments:
reference numerals in the drawings of the specification include: the movable claw group 1, the accommodating cavity 11, the elastic piece 2, the guide rod 3, the ball head 31, the cover body 4, the limiting piece 5, the protruding part 51, the screw 6, the hammering head 7, the sliding chute 71, the insert A and the die B.
An embodiment is substantially as shown in figures 1, 2 and 3 of the accompanying drawings: a hammering type dismounting tool comprises a cover body 4, wherein a cavity with a conical surface is arranged on the inner side of the cover body 4. The movable claw set 1 is arranged in the cover body 4, and in this embodiment, the movable claw set 1 is preferably formed by three movable claws, and the three movable claws are distributed in an annular array. The three movable claws are surrounded to form a containing cavity 11 coaxial with the cover body 4, and the outer sides of the movable claws are matched with the conical surface of the cover body 4. An ejector rod is connected to the cover body 4 in an axial sliding manner, and a ball head part 31 is arranged at one end of the ejector rod, which faces the movable claw group 1. The movable claws are provided with grooves matched with the ball head part 31 in shape, and the three movable claws are wrapped on the outer side of the ball head part 31 through the grooves. A gap is provided between the ejector rod and the side of the movable claw located at the groove far from the accommodating cavity 11, so that the movable claw can swing around the ball head part 31 through the gap.
