What are the design steps and requirements of thermoplastic injection mould?
step is provided according to the plastic parts design shape, size, material, technical requirements and the requirements for the number of mold cavity, and a computing parts quality required injection volume, injection molded parts distribution in the mold on the total projection area and the clamping force, and a preliminary estimate the shape of the mould size.Then select the injection machine specification, make the machine tool's rated injection quantity, rated locking force, mounting dimension, open die distance meet the requirements.After the injection machine is determined, the parameters related to the mold design can be obtained, such as the diameter of the positioning ring, the diameter of the nozzle, the spherical radius of the nozzle and the parameters of the ejector rod.
Should be considered when determining mold concrete structure, can obtain the required shape and size accuracy and surface quality requirement, and as far as possible, reduce the secondary processing plastic parts, also consider forming high efficiency and reliable use, and to ensure the durability and manufacturing cost of production.
