[0002] A ballpoint pen is a pen that uses a ball at the front end of the pen or refill to roll out the writing medium. It uses a tiny rotating ballpoint made of brass, steel, or tungsten carbide to release ink onto paper when writing. Ballpoint pens are very different from their predecessors - reed pens, feather pens, metal-tipped pens, and fountain pens. To ensure the user's feel when using, the pen barrel of a ballpoint pen is usually made into a round barrel. When producing the pen barrel, an injection mold is required. However, the injection molds currently used on the market are not convenient for separating the mold, which makes demolding difficult and reduces injection molding efficiency. To this end, an efficient injection mold for pen barrel production is proposed. Utility Model Content
