Description

Technical Field

[0001] The invention relates to the technical field of injection molds, and more particularly to an injection mold with a plastic recycling function. Background Art

[0002] An injection mold is a precision tool used in the production of plastic products. It uses an injection molding machine to inject molten plastic material into the mold cavity under high pressure, and then cools and solidifies to form the desired plastic product. An injection mold usually consists of two parts: a movable mold and a fixed mold. The movable mold usually refers to the movable part, while the fixed mold is the fixed part. Together, they form the shape and size of the plastic product. During the injection molding process, the molten plastic enters the runner system of the mold and is then distributed to each cavity. The plastic in the runner is usually not used in the final product after the product cools, so it needs to be removed to form waste.

[0003] In the existing production process of small and medium-sized injection molding accessories with simple structures, the initial flow is mostly carried out through a single injection molding channel, and a diversion channel is used to perform the injection molding of multiple small and medium-sized accessories. This method can effectively improve the production injection molding efficiency, but this method produces a lot of injection molding waste in the diversion channel, resulting in a waste of injection molding raw materials. Therefore, how to propose a multifunctional injection molding mold to facilitate large-scale injection molding production in a short time and optimize the injection molding raw materials in sufficient time is particularly important; in view of this, we propose an injection molding mold with plastic recycling function.
