The invention discloses a plastic pencil lead core extrusion forming mold, and relates to the technical field of plastic pencil manufacturing. The mold comprises a connecting seat; the connecting seatis of a rectangular block structure, a plurality of heating wires are installed on one side of the connecting seat, and a through hole is formed in the center of the connecting seat; a mold head is arranged in the through hole of the connecting seat, and a shell is connected to the connecting seat in a threaded mode; the shell is of a cylindrical structure, and a guide pipe is connected to the bottom of the shell; and a heating hoop is installed on the circumferential side of the shell. According to the mold, the heating wires and the heating hoop are used for carrying out heating and heat preservation on the connecting seat and the shell respectively, the temperature required by the production of the lead core is ensured, the production quality of the lead core is further improved, the mold head is clamped in the shell, the installation mode is simple, the mixed raw materials are enabled to flow into the conical mold head, after the raw materials are extruded, the raw materials are flowing out through a pipe, the forming mode is simple, the whole equipment is easy to operate, the use is convenient, and the production cost is low.
Description
technical field [0001] The invention belongs to the technical field of plastic pencil manufacturing, in particular to a plastic pencil core extrusion molding die. Background technique [0002] Traditional pencils are wooden pencils, which consume a large amount of wood every year, which does not conform to the background of energy conservation and environmental protection vigorously advocated by the state, and affects the development of the wooden pencil industry. And the wood pencil processing process is complex, the main process includes: wood cutting, machine grooving, core addition, glue addition, cladding, high temperature curing, segmentation, painting, roll printing, inspection, packaging, sealing, boxing, storage etc., the production cost is high. [0003] All-plastic environmentally friendly pencils are all made of waste plastics. It is extruded by a plastic pencil core making machine, a rod making machine, and a skin color extruder, and the color is selected elect...
