Nutritional pump tube has precise design and manufacturing process to ensure accuracy and safety during the infusion process, so as to effectively supplement the nutrition needed by patients. Medical pump tube usually requires the use of molding molds during production.

[0003] Liquid silicone, also known as liquid silicone, is relative to solid high-temperature vulcanized silicone rubber. It is a liquid glue with good fluidity, fast vulcanization, safer and more environmentally friendly characteristics, and can fully meet food grade requirements. Liquid silicone has excellent tear resistance, resilience, anti-yellowing, thermal stability, heat resistance and anti-aging, etc. It is mainly used in infant products, medical supplies and electronic products. After liquid silicone injection molding, workers are usually required to hold a hair dryer to blow the lower mold to blow out the residue on the lower mold to avoid residual residue on the lower mold, which will lead to defects in the next molding. Therefore, it not only increases the labor intensity of workers, but also reduces production efficiency.

[0004] In this regard, the Chinese patent application number CN202022579668.X discloses a liquid silicone high-efficiency injection molding mold, including a base, a U-shaped bracket is fixedly provided at the top end of the rear side of the base, a lower mold base is slidably provided at the top end of the base, and an upper mold base matching the lower mold base is slidably provided in the U-shaped bracket, which can effectively blow out the residue on the lower mold to avoid affecting the quality of the next injection molding, and at the same time can effectively improve the production quality.
