Description

TECHNICAL FIELD

[0001] The utility model relates to the field of plastic bucket injection molding, especially to a plastic bucket injection molding production injection molding machine material returning device. BACKGROUND

[0002] The plastic bucket injection molding machine is a high-efficiency injection molding equipment specially used for manufacturing plastic buckets. The equipment heats and melts plastic raw materials, injects them into a mold, and forms the required plastic bucket product after cooling and solidification. The process of taking out the formed plastic bucket from the mold is usually called "material returning".

[0003] Most of the existing injection molding machine material returning devices push the formed plastic bucket out from the lower end through the jacking mechanism at the lower end. This method often requires manual removal of the plastic bucket by personnel. Frequent material returning operations increase the burden on operators and are relatively low in efficiency. Moreover, some molds only use natural cooling to solidify the raw materials after injection molding, which greatly reduces production efficiency.
