摘要： Disclosed are a power time sequence conversion method and device for manufacturing products in batches. A common power is sequentially coupled with power input ends of a plurality of execution mechanisms in different time periods, so as to provide in time order a plurality of power drives required during a batch manufacturing process of products, or provide power drives in different forms such as movements and forces to the same execution mechanism in a relaying manner in two adjacent time periods. A change gear capable of rotation and revolution is sequentially meshed with a plurality of tail end driving gears in different time periods, wherein the tail end driving gears are uniformly distributed in the circumferential direction and serve as power outputs, the revolution of the change gear is braked after each meshing to achieve the power drive of a certain execution mechanism in batch manufacturing of the products, and meanwhile, power drives in different forms such as movements and forces are provided to the same execution mechanism in a relaying manner through a torque converter. Compared with the conventional batch manufacturing of products where a plurality of independent power drives are required, the present invention has remarkable characteristics in low cost, low energy consumption, high reliability, good stability and the like.

摘要： Developing a volume in a shooting pot reservoir (28) is achieved through the selective coupling and de-coupling of an injection piston (34) to a plunger (38). Following successive injection ( FIG. 5a ) and hold phases ( FIG. 5b ) of an injection molding process ( FIG. 5 ), the runner and channel system is partially de-compressed ( FIG. 5c ) by drawing back together, over a short distance, the plunger (38) and the injection pressure (34) as one unit. The injection piston is then mechanically de-coupled from the plunger ( FIG. 5e ), with the injection piston (34) withdrawn to essentially its final shot position, but minus a customary packing distance (8). Plastic melt (100), extruded into a shooting pot (28) positioned in front of the plunger (38), is permitted to push the plunger backwards, but now with minimal work expenditure. When the plunger again contacts ( FIG. 5f ) the injection piston (34), melt pressure now causes both units to be moved back to reach a final shot size volume. Finally, the injection piston (34) drives the plunger (38) forward to eject melt accumulated within the shooting pot (28).

摘要： It is enabled to produce in short time a molded product having a shape resembling that of a three-dimensional, deep-bottomed, concave container having a thin side wall, even by use of a molding material of poor moldability, such as an environmental low-load-type material. Before completion of a mold closing step of a mold apparatus, charging the molding material into a cavity of the mold apparatus is started; before completion of the mold closing step, charging the molding material in a predetermined amount is completed; and after completion of the mold closing step, a mold clamping step of the mold apparatus is performed so as to produce a molded product of the environmental low-load-type material

摘要： A metering device is disclosed for use in a plastics moulding machine having a mould cavity (16), relatively movable platens (10,12) and a means (26) for feeding a plastics melt into the cavity. The metering device comprises a heated block (22) interposed between the feeding means (26) and the mould cavity (16). A cylinder (34) with a moving piston (37) is formed in the block (22). A first passage (28,32) in the block (22) connects the cylinder (34) to the feeding means (26) and a second passage (32,40) connects the cylinder (34) to the mould cavity (16). Valves (30) in the passages (28,32,40) enable the cylinder (34) to be filled by the feeding means (26) without the melt entering the mould cavity (16) and subsequently enable the desired dose of plastics melt, when ejected from the cylinder (34) by the piston (37), to flow from the cylinder (34) to the mould cavity (16) without being returned to the feeding means (26).
