Description

Injection molding device with ejection function

Technical Field

The utility model relates to the technical field of injection molding devices, in particular to an injection molding device with a material ejecting function.

Background Art

The injection molding device, also known as the injection molding machine, is a main molding equipment that uses a plastic molding mold to make thermoplastic plastics or thermosetting plastics into plastic products of various shapes. This process is achieved by the injection molding machine and the mold. The injection molding process includes melting the plastic at a high temperature of about 200°C, then pushing it into the mold, and then cooling and solidifying. The injection molding machine is mainly composed of two devices: one is an injection device for pushing the molten plastic into the mold, and the other is a clamping device for clamping the mold to prevent it from opening. Publication No. CN216100116U discloses an injection molding device, which can effectively solve the problem that the injection molding cylinder is prone to shaking when it moves downward, thereby affecting the normal use of the injection molding cylinder, through the setting of parts such as pulleys, sleeves, sliders, rectangular columns and slide rails. However, after the injection molding cylinder is completed, the data line protection terminal that is injected and processed may be stuck inside the lower mold seat, making it difficult to achieve rapid demolding. Sometimes manual demolding is required, which affects the production flow rate of the injection molding device. Therefore, it needs to be improved.
