Hollow plastic bucket rear cooling and off-edge system

I. Post-COOLING unit

For positioning, fixed-point cooling.

The cooling air source can also have a common gas source and low-temperature gas source points.

The rear cooling system and the flying edge System are two important auxiliary devices for the hollow blow molding machine, this paper introduces the two devices.

One rear cooling unit
Mold cooling is the most commonly used in extrusion blow molding cooling, the mold in the die, the melt is close to the mold cavity wall, the heat of the melt through the wall, through the mold wall to the cooling medium transfer and reduce, and the container gradually cooled stereotypes. After the cooling device, is the initial cooling molding products removed from the mold, in the outside of the mold to continue cooling device.
This cooling method can reduce the cooling time of the product in the mold, shorten the production cycle and improve the efficiency.

For the actual needs of different products, the post-cooling system can be targeted at different parts of the product (generally higher temperature parts) For the machine's own characteristics, the rear cooling unit can be integrated in the equipment, or can be used as the auxiliary unit alone. General Small hollow molding machine with integrated post-cooling device-based, large-scale hollow forming machine to the post-cooling molding device-based.

II. Auto-deflashing device

To the flying edge device is the product after molding, the product mouth and the bottom of the excess waste removal device. The small blow molding machine's flying edge device is generally installed in the mold back plate, with the mold, can also be installed on the machine, and the mold separate.
The flying edge device of large-scale hollow forming machine is generally used as an independent auxiliary machine.

At the mouth of the flying edge device there are two, one is the direct push will fly edge, the other is a rotary incision, through the installation of the blade rotation, cut off the mouth of the flying edge.
