Description

Technical Field

[0001] This utility model relates to the technical field of blow molding apparatus, and in particular to a blow molding apparatus for manufacturing plastic buckets. Background Technology

[0002] Hollow blow molding is a rapidly developing plastic processing method. A tubular plastic preform, obtained by extrusion or injection molding of thermoplastic resin, is placed in a split mold while still hot. After the mold is closed, compressed air is immediately introduced into the preform, causing it to inflate and adhere tightly to the inner wall of the mold. After cooling and demolding, various hollow products are obtained.

[0003] For example, in a prior art represented by application number CN202221974087.9, the main structure includes a support frame, a preform die head, a moving mold clamping assembly, a fixed plate, a preform cutting assembly, and a blow molding assembly. The preform die head is located on top of the support frame, and two moving mold clamping assemblies are symmetrically arranged on the support frame. The material handling mechanism includes a first driving component and a mechanical claw. The first driving component is mounted on the support frame, and the mechanical claw is located at the end of the piston rod of the first driving component. When this blow molding device for manufacturing plastic buckets is used, the component installation positions are reasonably allocated, enabling the material unloading operation to be completed longitudinally. This allows the parts to quickly detach from the moving mold clamping assembly and the blow molding assembly, shortening the transfer waiting time and thus improving the production efficiency of plastic buckets.
