Structure Design Of Locking Device For Medium Sized Injection

Molding Machine

Abstract

This design is a medium-sized injection machine mould locking device structure design, injection molding machine lock mould device can ensure reliable mold closing and opening and ejection products. This article mainly introduces the injection molding machine lock mould device type and structure and the hydraulic cylinder selection calculation and so on. With the development of the times and the progress of industry, hydraulic industry put forward new requirements to it. Medium-sized injection molding machine lock mould device of hydraulic control system in injection mold work plays an important role. It has a direct impact on the plastic parts molding and mold performance. Therefore, medium-sized injection molding machine lock mould device of hydraulic control system design is the inevitable trend of the current hydraulic industrial development, in the next few years, play a more and more important role.

This design is a mold device structure design of medium-sized injection molding machine lock, through the new medium injection molding machine lock mould device of the structure and hydraulic design, making this type medium-sized injection molding machine lock clamping apparatus using range more widely, in the field of plastic mold will play a more and more important role.

Key words: medium-sized injection molding machine clamping device, hydraulic cylinder, control, effect.
