Syringe mould design and manufacturing are closely rela […]
Syringe mould design and manufacturing are closely related to plastic processing. The success or failure of plastic processing depends largely on the effect of mold design and mold manufacturing quality, and the design of plastic molds is based on the correct design of plastic products.
The structural elements to be considered in the design of the syringe plastic mold are:
① Parting surface, that is, the contact surface where the concave mold and the convex mold cooperate with each other when the mold is closed. The selection of its location and form is affected by factors such as product shape and appearance, wall thickness, molding method, post-processing technology, mold type and structure, demolding method, and molding machine structure.
②Gating system, that is, the feed channel from the nozzle of the injection molding machine to the cavity, including the main runner, the runner, the gate and the cold cavities. In particular, the selection of the gate position should be conducive to the molten plastic filling the cavity in a good flow state, and the solid runner and gate cold material attached to the product are easy to eject from the mold and be removed when the mold is opened (hot flow) Except for road model).
③ Plastic shrinkage rate and various factors that affect the dimensional accuracy of products, such as mold manufacturing and assembly errors, mold wear, etc. In addition, when designing compression molds and injection molds, the matching of the process and structural parameters of the molding machine should also be considered. Computer-aided design technology has been widely used in plastic mold design.
