Description

Technical Field

[0001] The utility model relates to the technical field of injection molding devices, in particular to an injection molding device which is easy to discharge materials. Background Art

[0002] Publication No. CN214163847U discloses a device for injection molding a product housing. The device includes a mold comprising multiple cavities for molding the product housing and flow channels connecting the cavities. Thin adhesive grooves are provided on either side of the flow channels. The utility model provides thin adhesive grooves on either side of the flow channels. During injection molding, the thin adhesive grooves cool and form first at the locations where the thin adhesive grooves are located. When the injection pressure is increased, the sol in the middle of the flow channels continues to flow. This prevents flash on either side of the nozzle after molding under high injection pressure, effectively extending the mold life. The device is particularly suitable for use in large molds with multiple cavities. Traditional methods rely on manual tools to remove the workpiece, which is cumbersome and prone to scratches or damage from repeated contact, affecting the quality of the finished product. Manual removal also increases the time required for the unloading process, limiting production efficiency. It also poses safety risks, especially in mass production, as it requires high manual labor and is prone to fatigue and misoperation. The shortcomings of traditional methods in terms of automation and safety limit the performance of the equipment in efficient production and require improvement. Utility Model Content
