Pen core plastic mould for electronic pens

Abstract

The invention provides a pen core plastic mould for electronic pens. 4 identical cavity groups are distributed in the shape of a Chinese character ''tian'' on a cavity plate, and are communicated by an H-shaped main flow channel. Each cavity group is provided with 8 equal-sized cavities that are arranged side by side in parallel along the vertical direction, every two cavities form a unit, and the two cavities of each unit are communicated with a first sub-flow channel, the first feeding gate of every two first sub-flow channels is communicated with a second sub-flow channel, and the second feeding gates of two second sub-flow channels are communicated with a third sub-flow channel, the center of which is provided with a third feeding gate. Through intercommunication of the first sub-flow channels, the second sub-flow channels and the third sub-flow channel, injection molding of the 32 cavities can be completed simultaneously. Injection molding can be completed at the same time of guaranteeing the amount of plastic entering the cavities. With the advantages of fast injection molding, simple structure and easy maintenance, the mould provided by the invention effectively improves the work efficiency and increases the yield.

Description

technical field [0001] The invention relates to a mold, in particular to a pen core plastic mold of an electronic pen. Background technique [0002] When using the injection molding process to form plastic products, due to the structural factors of the mold, the injection mold for the electronic pen refill is generally complicated to form between the cavity structure and the runner, which makes the production efficiency low, and the production quantity of the refill is also low. Not a lot, reducing production volume and thus increasing costs. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a plastic mold for the refill of an electronic pen. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] The plastic mold for the refill of the electronic pen includes a static template, a cavity plate and a moving template. The cavity plate is p...
