Thread unscrewing units

Product catalog summary

Overview: The document provides comprehensive information on hydraulic thread unscrewing units used in injection molding processes. These units are designed to efficiently unscrew threads from molded parts, offering high precision and adaptability for various thread sizes and types.

Specifications: The document details various models of unscrewing units, including single, twin, and angle units, specifying power (kW), speed (rpm), displacement (cm³), and dimensions. The units are capable of handling right-handed and left-handed threads, with unscrewing lengths up to 95 mm and thread diameters ranging from 3 to 35 mm. Two main models, Z 5411 and Z 5421, are highlighted, each with specific capabilities and torque specifications.

Types of Units:

Single Unscrewing Units: Ideal for demoulding a single internal thread quickly and easily, suitable for direct installation in or on the mould.
Twin Unscrewing Units: Used for demoulding two internal threads simultaneously, maintaining the same level, direction, and pitch.
Angle Unscrewing Units: Designed for use in limited spaces, serving the same purpose as single units.

Technical Data: Detailed tables provide specifications such as power, speed, displacement, and dimensions for various unit types. Additional data includes operating pressure, temperature resistance, and flow rate specifications for core cooling and tempering control filters.

Installation and Usage: The units can be combined in different configurations to suit specific moulding requirements. The document also mentions the availability of units in other dimensions upon request.

Features: Key features include high unscrewing speeds (up to 2,000 rpm), significant torque, and hydraulic motors available in 2.6 kW, 3.2 kW, or 6.1 kW. The units offer different unscrewing lengths and center distances, accommodating internal threads with outside diameters up to 78 mm.

Procedures: The document outlines the working steps for using the unscrewing units, including extending the thread core, injecting the molding, retracting the thread core, and ejecting the finished part. The servo-controller is pre-programmed with functions like 'remove the core in the mold' and 'return the core to the unit'.

Advantages: The units are robust, easy to handle and maintain, and suitable for both right-hand and left-hand threads. They ensure high precision and reproducibility, making them ideal for large-batch production. Retrofitting existing molds is also possible.

Applications: These units have been successfully used in the production of plastic and metal injection-molded parts for over a decade, providing consistent high precision for internal threads. They are suitable for cleanroom production, food industry, and medical technology.

Recommendations: For optimal performance, each servomotor requires its own motor control and voltage supply. The document advises caution during manual operations due to the full torque capabilities of the units.
