Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a processing machine for deburring a mold (core).

[Conventional technology]

A mold made by a mold making machine inevitably has burrs.

The conventional technology for deburring machines that remove these burrs includes a core deburring device that is installed at an intermediate position of the stand frame and moves up and down by the action of a cylinder using a pole as a guide, as disclosed in Japanese Patent Application Laid-Open No. 58-212836. When the pallet is fed directly under the core deburring device, the core deburring device lowers, and then one moving plate and the other moving plate move in the opposite direction to remove the tension wire from the core. The wire is brought into contact with the occurrence site and bent and deformed into a dogleg shape or an inverted dogleg shape.

Then, while maintaining the deformed state, the burr is removed by the wire by vertical movement of the core deburring device.

[Problems to be Solved by the Invention] Since burrs are removed using a wire that is bent and deformed into a dogleg shape, there is a problem in that it is not possible to remove burrs from complex-shaped molds that have recesses.

In particular, when two molds are used in combination as shown in FIG. 4, the burrs on the upper and lower outer periphery cannot be removed by mechanization.

For this reason, there was a problem in that the deburring work had to be carried out manually, which was time-consuming.

Therefore, the object of this invention is to provide a mold processing machine that can mechanize the burrs on the upper and lower outer periphery.

[Means to solve the problem]

In order to achieve the above object, this invention has a transfer device installed to transfer the mold supplied on the jig on the upper surface, a multi-jointed transfer device disposed above and below the mold stopped in front of the mold supply position, and It is composed of a robot having two deburring rotary blades at the tip of the arm above and below the outer periphery of the mold, and a penetrating hole for the rotary blade provided in the transfer device so that the lower rotary blade faces the lower burr. .

[Effect]

The mold supplied on the jig is transferred to the processing position by a transfer device, and the upper and lower robots are numerically controlled to deburr two stripes on the upper and lower outer periphery of the mold using a rotary blade at the end of a multi-jointed arm.

Note that the lower rotary blade is passed through the through hole of the transfer device to perform deburring work.

After the deburring work is completed, the robot stops operating and
Next, the mold from which deburring has been completed is transported to the unloading position by a transfer device, and the mold is unloaded.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is a jig 2 for supporting mold A on the top surface.
This is a transfer device provided to transfer the mold A supplied to the jig 2.

The above-mentioned transfer device 1 includes a table 5 in which a central support shaft 3 on the lower surface is supported by a bearing 4 in the illustrated case, and a cylinder 8 provided to advance and retreat a rack 7 that engages with a pinion 6 fixed to the support shaft 3. First, the mold A is supplied from the supply/unloading position to the jig 2 placed at two locations on the periphery of the table 5, and then the rack 7 is moved back or While moving forward, the pinion 6 is driven to rotate the table 5 by 180 degrees and send the mold A to the processing position. In addition, the mold A was supplied to the empty jig 2 that had returned to the supply/unloading position, or the deburred mold A was taken down. It's okay.

The mold A to be supplied to the jig 2 is molded individually, and is obtained by fitting two molds together from above and below as shown in FIGS. 3 and 4. There are barriers a and a.

In addition, in the case shown in the figure, the lower surface of the upper mold A and the lower surface of the lower mold A, which are assembled in a stepped manner, are supported by four protruding pieces, but the jig 2 may be supported by a method other than the above. In some cases.

Further, above and below the mold A stopped at the processing position, robots 12 and 12' having a rotary deburring blade 10 at the tip of a multi-joint arm 9 are installed, and the multi-joint arm 9 is operated by numerical control to remove the upper The downward rotating blade 10 of the robot 12 is driven by the motor 13 to deburr the upper barrier and a part of the lower barrier a, and the upward rotating blade 10 of the lower robot 12' is driven by the motor 13. Perform deburring work on the lower side.

Depending on the method of supporting the mold A, the upper barrier 10 may be removed by the rotary blade 10 of the upper robot 12, and the lower barrier 10 may be removed by the rotary blade 10 of the lower robot 12'.

Further, the table 5 is provided with a through hole 14 through which the rotary blade 10 of the lower robot 12' passes.

〔effect〕

As described above, by using the mold processing machine according to the present invention, burrs located above and below the outer periphery of the mold can be removed extremely easily and quickly.
