The workplece shown in Fig. 6.64 is provided with a fine intermal thread. The plastic material flows into the nest through the side gate. The workpiece thread is machined by spring-operated slee...

In Fig6.63 the unscrewing gears 2 are driven by the motor through a pair of bevel gears 5. After the mold opened, the motor drives a pair of bevel gears 5, the gear 3 turns because gear 3 is connec...

Motors, electric, pneumatic, hydraulic can be used in the plastic injection molds for the turning of threaded workpieces

Fig 6.61 is a configuration of unscrewing of threaded cores with rack and gear. The rack 1 is fixed to the stationary clamping plate. Following solidification of the workpieces, the mold opens, gea...

The gear segment 2 is connected to the rack I which drives the unscrewing gears, as shown in Fig.6.60.

Standard molds are made in most of the plastic processing plants for the production of these caps, where by replacement of a few parts caps of different size and shape can be produced.

The coarse threaded spindle 1 can be arrange on the side of the mold if a high mold cannot be mounted on the machine as shown in Fig 6.58

A large number of caps of varying size and shape are udes in the food industry, such as on bottles ofcosmetics and detergents and in several other applications. In most cases the threaded core is s...

The workpiece is rotation body and a hole is in its centre, then, from experience the suitably oriented and deformed, workpieces canbe produced by application of the umbrella gate or diaphragm gate...
