Plastic mold for electronic pen holder

Abstract

The invention provides a plastic mold for an electronic pen holder. The plastic mold comprises a static template, a cavity plate and a dynamic template, wherein eight cavities, sprues communicated with the cavities and runners communicated with the sprues are formed in the cavity plate, the overall dimensions of the eight cavities are completely consistent, the eight cavities are arranged in parallel along the horizontal direction, every two cavities are taken as a unit, the two cavities in each unit are communicated with each other through the runner, the runners are communicated with the corresponding sprues, the shape of the cavities is consistent with the shape of the pen holder, sliding chutes are formed in one sides of the cavities, push rods are arranged in the sliding chutes and are opposite to the cavities, and one ends of the push rods are fixed on connecting rods which are connected with piston rods of air cylinders by driving. Through the structure that one runner corresponds to two cavities for simultaneous injection molding, glue entering the cavities is ensured to be equal, and then the air cylinders are adopted for driving the push rods to complete molding. The plastic mold is simple in structure and fast in injection molding, and can increase the yield and effectively improve the working efficiency.

Description

technical field [0001] The invention relates to a plastic mold of an electronic pen holder. 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 pen holder of the electronic pen is generally complicated to form between the cavity structure and the gate, which makes the production efficiency low. The burr or the pen tube is not smooth enough, which will easily make the mold unqualified, reduce the pass rate of the product, and increase the cost. 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 penholder of the electronic pen. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] The plastic mold of the pen holder of the electronic pen includes a static template, a cavity plate and a movable template....
