An EDM multi-mold finishing equipment

Technical field

The present application relates to the technical field of mold processing, and in particular to an EDM multi-mold finishing equipment.

Background technique

The mold can process metal materials into the required products or parts according to the needs. When the mold is processed, it is usually roughed and heat treated before finishing. However, after the mold is heat treated, its surface hardness is relatively high, so that It is more expensive to directly grind with an ordinary lathe, so EDM is usually used.

However, before processing, the mold needs to be clamped and the level of the mold adjusted to keep the mold level and clamped before processing. The current adjustment method is usually to place a level on the surface of the mold to detect the level of the mold. , the level will be taken away directly after the adjustment is completed. However, if the operation is not standard during subsequent processing, it will also cause the levelness of the mold to change, thus affecting the processing accuracy of the mold.

Therefore, a new technical solution needs to be proposed to solve the above problems.

Contents of the invention

In order to be able to observe whether the levelness of the mold processing surface changes at all times during the mold processing, this application provides an EDM multi-mold finishing equipment.

The clamp base is threaded, and the leveling bolt passes through the clamping block and abuts against the clamp base. The leveling bolt is arranged on the side of the fastening bolt away from the mold.

By adopting the above technical solution, after the mold is clamped and positioned by the clamping block, the clamping block can remain parallel to the upper end surface of the mold, so that when downward pressure is applied to the mold, the mold is less likely to be affected by a force-bearing area that is too small. The deformation occurs, and at the same time, the first level installed on the clamping block is used to detect changes in the levelness of the mold. During the processing process, if the levelness of the mold changes, external force will be exerted on the clamping block, resulting in clamping. The holding block also produces a certain displacement, which causes the bubble of the first level to move, so that it can be conveniently observed whether there are changes in levelness during the mold processing process, so that the processed molds are more in line with standards.
