Problems solved by technology

[0003] like figure 1 As shown, when the pen cap is injection molded, the volume of the product is relatively small and the shape is relatively special, which makes it difficult to ensure the molding quality of the product such as no flash and full filling in the molding and pouring methods. It is necessary to design a special thread removal mechanism and mold. structure to complete the automated injection molding production of the product

Abstract

The invention provides a threaded injection mold for a pen cap and a use method of the threaded injection mold. The threaded injection mold comprises a mold base structure component, a molding component, a thread relieving mechanism component and a mold ejection mechanism component; a one-mold four-cavity layout is adopted, and a casting mode is a central pin-point gate mode; half of a runner and half of a sprue are arranged on a left slider and a right slider, the mode that pouring gates are arranged on the sliders is adopted, and the overall pouring runner consists of the left slider and the right slider which are combined together. By adopting the technical scheme, the practical production problems that a product sprue is difficult to form, many flanges exist and filling is not full in the pen cap product injection molding process are solved, zero-defect automatic molding production of a product can be realized through simple mechanisms, and the product molding quality is effectively guaranteed; the threaded injection mold is reasonable in structural design and compact in structure and is safe and reliable.

Description
