Abstract

The invention discloses manufacturing equipment and method for a stylus pen point capable of ensuring centering of an insert, the manufacturing equipment comprises a first module used for forming a first color body, a second module used for forming a second color body, and a transfer device arranged between the first module and the second module, during injection molding, the transfer device turns over the first color body and transfers the first color body to the second module, and the first color body is transferred to the second module; and the second module completes injection molding of the second color body. According to the invention, the position stability of the insert in the injection molding process is ensured, so that the insert keeps centered encapsulation in a final product, thereby ensuring the accuracy of pressure sensing and roll sensing of a pen point, being competent for various precise drawing and writing tasks, and improving the yield of the product.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to a manufacturing device and a method for a stylus pen tip that ensures the centering of an insert. Background technique [0002] In the injection molding industry, as a unique injection molding mold, the two-color injection mold can complete the injection molding production of some combination products of various materials, such as some handwritten capacitive pens used in electronic devices such as smart phones and tablet computers. At present, capacitive pens are mainly divided into passive capacitive pens and active capacitive pens. Passive capacitive pen is an auxiliary device that uses conductive materials to imitate human hands and fingers to complete man-machine dialogue. The metal in the tip of the active capacitive pen will continuously emit low-frequency signals to feedback the pressure and roll degree felt by the tip of the pen. Therefore, the active capacitiv...
