Pen cap production mould, there is body, there is column chamber on body, column chamber is blind hole;

Column intracavitary is sequentially fixedly connected with pylon, frustum, accommodating chamber post by bottom surface to opening；

Column chamber, pylon, frustum, accommodating chamber post, four is coaxial；

Column chamber, pylon, frustum, accommodating chamber post, the total height after four connections are equal to the depth of column chamber.

Further：The bottom of column chamber also has a steam vent, is vented during for being molded.

Further：Also there is injecting hole.

Further：The chamber interface of column chamber is cylindric.

Further：The cylinder of pylon is regular hexagon.

Further：Accommodating chamber post is cylindric.

Further：It is coarse that the cylinder of pylon, which is, to increase the affixed ability of the friction of product.

Further：Full die is made up of a kind of two duplicate pen cap production moulds, pairing, and injection slot is located at The openend of column chamber.

Further：It is made using elastomeric material.

Entity, it is characterised in that：Using a kind of described pen cap production mould, produce.

Beneficial effect：

The product that the utility model is produced can by the use of Convenient pencil head, reduce waste, nib can also be protected not It is damaged, a kind of new approaches is provided.
