Description

Mechanical arm capable of automatically taking out residues of inlet gate

Technical Field

The invention relates to the technical field of automatic mold cleaning devices, in particular to a manipulator capable of automatically taking out residues entering a sprue.

Background

The gate, also known as the feed inlet, is a passage from the nozzle interface of the injection molding machine to the mold cavity, which is the smallest and shortest section of the runner system. In metal casting, it refers to the entry and passage of molten metal into the mold during casting. Often broadly referred to as a gating system. The function is that the feeding material is accelerated by utilizing the constricted flow surface, and the high shear rate can ensure that the feeding fluidity is good; the heating effect of viscous heating also has the function of increasing the temperature and reducing the viscosity of the material. The sprue is firstly solidified and sealed after the molding is finished, so that the functions of preventing feeding backflow and avoiding the shrinkage and depression of the molded product caused by too fast pressure drop of the cavity are achieved. After molding, the runner system and the molded part are conveniently cut off. Mold fouling occurs in injection molding of almost all thermoplastics. When the functional requirements of the end product necessitate the incorporation of relevant additives, these additives are very likely to remain on the cavity surface during the molding process, leading to the formation of mold scale. The mold surface is relatively easy to clean at the initial stage of mold scale formation, so the mold cavity and the exhaust passage must be cleaned and maintained regularly. The residues generated at the inlet gate of the mold during demolding can influence the next injection molding without cleaning.

Most of the mold gating gates on the market at present can only be cleaned manually, so that time and labor are wasted, and the cleaning effect is poor, so that the whole forming operation efficiency is influenced, and therefore a mechanical arm capable of automatically taking out gating gate residues is urgently needed in the market to solve the problems.
