[0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. Injection molding is a method of producing and shaping industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding compression molding and die casting. The advantages of injection molding method are fast production speed, high efficiency, automated operation, a wide variety of colors, shapes from simple to complex, sizes from large to small, and precise product size. The product is easy to update and can be made into complex-shaped parts. Injection molding is suitable for mass production and molding processing fields such as complex-shaped products. When the injection molding machine is processing, it is necessary to inject material into the injection molding machine, which requires a quantitative feeding structure for the injection molding machine.

[0003] The quantitative feeding structure of today's injection molding machines can basically meet people's needs, but there are still some problems. The specific problems are as follows:

When discharging materials, different amounts of materials need to be injected under different circumstances. It is difficult for traditional devices to quantitatively discharge materials and it is difficult to adapt to different situations. Sometimes, excessive discharge can easily lead to waste.

[0005] 2. It is difficult to replace the funnel of the injection molding machine with a quantitative feeding structure. In some cases, when different materials need to be fed, different funnels are often needed. When the six funnels cannot adapt to the required amount of material, the funnel needs to be replaced. The funnel cannot be replaced and is difficult to clean. Utility Model Content
