Description

A kind of mold with cathode protecting function moulding

Technical field

The utility model relates to a kind of molds, more particularly to a kind of mold with cathode protecting function moulding.

Background technique

In plating, it is easy to produce high potential at the wedge angle position of moulding, so that the coating accumulation even appearance burning at this is white Phenomenon.The accumulation of coating will cause the surface membrane thickness unevenness of product at wedge angle position, and then lead to deformation of products.

Notification number is that the Chinese utility model patent of CN202347098U discloses a kind of " crystallizer slab plating hard chrome yin Electrode protector ", has been bolted L-type fixture on crystallizer slab plate, and L-type fixture passes through conducting bolt for cathode Protection angle steel is fixed on the periphery of crystallizer slab plate, is welded with 2- close to the side of crystallizer slab plate in cathodic protection angle steel The small iron plate of 4mm thickness, cathodic protection angle steel can adsorb edge current together with small iron plate, solve plating after thickness of coating not Phenomena such as even, edge is burnt.But the slightly aobvious complexity of its structure, it needs to add angle steel being plated part edge, reduces production effect Rate.

Utility model content

The utility model aim is to provide for a kind of mold with cathode protecting function moulding, and can mold has The moulding of cathode protecting function solves the problems, such as that moulding how more efficiently to be made to have cathode protecting function.

In order to achieve the above objectives, the technical solution adopted in the utility model is:

The utility model provides a kind of mold with cathode protecting function moulding, including type chamber, the type chamber tool There is type chamber wedge angle position, the type chamber wedge angle position is surrounded with cathodic protection slot, and the cathodic protection slot is communicated with the type chamber.

Optimally, the depth of the cathodic protection slot is greater than its type chamber wedge angle bit depth wrapped.

Optimally, it is surrounded with cathodic protection slot around the type chamber.

Since above-mentioned technical proposal is used, the utility model has the advantage that compared with prior art

A kind of mold with cathode protecting function moulding of the utility model at mold cavity wedge angle position due to wrapping Be wound with cathodic protection slot, and cathodic protection slot is communicated with type chamber, in this way by mold injection molding go out moulding in, in moulding The cathodic protection item with cathode protecting function can be surrounded with around wedge angle position, which adsorbs when moulding is electroplated Electric current is protected at moulding wedge angle position, keeps thickness of coating at moulding wedge angle position uniform, and will not be white by burning, improves non-defective unit Rate.In addition, the mold of the utility model, which can be integrally formed, have been provided compared with adding cathode protection device on being plated part The moulding of cathode protecting function is not necessarily to additional processing, high production efficiency before plating.

Further, the depth of the cathodic protection slot of the utility model is greater than the depth of its type chamber wedge angle position wrapped, The height of the cathodic protection item on the moulding of injection molding with cathode protecting function can be made to be higher than wedge angle position height, it can Preferably carry out cathodic protection.

Further, it is surrounded with cathodic protection slot around the type chamber of the utility model, it can be more in all directions to note Plastic carries out cathodic protection, further improves the cathode protecting function of moulding, and then improve product yield.
