Abstract

The invention provides a pen cap thread injection mold which comprises a mold frame structure assembly, a forming assembly, a thread releasing mechanism assembly and a mold ejecting out mechanism assembly. According to the structure layout of the mold, four cavities are formed in the mold, and a central point pouring gate mode is adopted as the gate mode. Halves of runners and halves of pouring gates are arranged on left sliding blocks and right siding blocks respectively, the mode of arranging pouring channels on the sliding blocks is adopted, and the overall pouring channels are formed by petal combination of the left sliding blocks and the right sliding blocks. By means of the technical scheme, the pen cap thread injection mold solves the practical production problems that in the technology of injection molding of pen cap product molding, product pouring gates are difficult to form, trimming is much, filling is not full; the zero-defect automatic molding production of the products can be achieved through a simple mechanism, and the product forming quality is effectively ensured. The structure design is reasonable, the structure is compact, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to the field of injection mold mechanism design, in particular to a pen cap thread injection mold. Background technique [0002] Such as 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. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pen cap thread injection mold, which is reasonable in design, compact in structure, stable in operation, safe and reliable, and convenient to use; in order to solve the above-mentioned existing technical problems, the present invention adopts the following s...
