Description

Helmet injection mold Technical Field The utility model belongs to the technical field of injection mold instruments, and particularly relates to a helmet injection mold. Background With the increasing diversity of transportation modes, helmets are used as key protective equipment for guaranteeing the safety of riding personnel, and market demands continuously rise. From common riding of bicycles and electric vehicles to high-speed sports scenes such as motorcycles, racing vehicles and the like, the helmet plays an indispensable role, and the risk of head injury can be effectively reduced. In the production process of the helmet, the injection molding process is important. The injection mold is used as a core tool for molding, and the quality and the production efficiency of the helmet are directly determined. The high-quality helmet is required to have an accurate outline, fit with the head structure of a human body, provide comfortable wearing experience, and ensure that the strength of the internal structure meets the standard and meets the safety protection standard. Different types of helmets, such as civil commute helmets and professional athletic helmets, have obvious differences in design, and the requirements on the precision and the complexity of the injection mold are different. The traditional mould development means is difficult to meet the demands of diversification of helmet styles and high production efficiency at present. Therefore, the development of the helmet injection mold with strong adaptability and high precision is urgent, the booster helmet manufacturing industry improves the productivity, optimizes the product quality, and protects the riding safety. Based on the above, the existing helmet injection mold still has short plates, and part of the molds are relatively poor in automation, and the molds need to be manually opened, so that the efficiency is relatively low, the molds are easy to damage when opened, and the molds are relatively complex to replace, so that the device capable of being opened and closed rapidly and replacing different molds is particularly important.
