[0002] An injection molding device generally refers to an injection molding machine. An injection molding machine has the ability to mold plastic products with complex shapes, precise dimensions or dense textures with metal inserts in one go. It is widely used in national defense, electromechanics, automobiles, transportation, building materials, packaging, agriculture, culture, education, health and people's daily life. It is the main molding equipment for making plastic products of various shapes from thermoplastic plastics or thermosetting plastics using plastic molding molds. At the same time, when producing some smart watch straps, an injection molding device is also required to produce plastic watch straps. Announcement No. CN214562453U discloses an injection molding device, which relates to the technical field of injection molding equipment. The purpose of the utility model is to provide an injection molding device that is easy to separate from profile molds, has a high degree of automation, and improves the overall injection molding efficiency of the equipment. The technical key point is an injection molding device, including a base, a connecting rod is fixedly installed on the top of the base, and the connecting rod A fixing rod is fixedly installed on the top of the mold, and there are four connecting rods and fixing rods. An upper mold is movably installed between the outsides of the four connecting rods, and a barrel is fixedly installed on the top of the upper mold, and a rotating motor is fixedly installed on the top of the barrel. The technical effect is that the cavity is set in the orientation of the upper core at the bottom, which is convenient for separating the profile from the cavity, and at the same time, the fixed cylinder is energized to drive the lower mold to move downward, so that the core passes through the through hole into the inner cavity of the base, and the profile is blocked by the top wall of the base and remains on the top of the base to achieve separation from the core. This product can easily and smoothly dismantle the finished product for cleaning, but it is not convenient to clean the waste after production, and it is easy to cause some fine waste to remain inside the module. When producing again, the fine waste is mixed with the material, which is easy to cause the finished product to contain debris, reducing the quality of the finished product. The practicality is poor and needs to be improved. Utility Model Content
