Specific embodiments
The outer plasticizing of specific embodiment 1. system extrudes, the injection of interior plasticizing system
The present case integrated extrusion molding and injection molding machine mainly comprises: hydraulic motor (1), transmission device 1 (2), transmission device 2 (3), machine barrel (12), charge door 1 (4), charge door 2 (5), external screw rod (6), inner screw (7), check ring (8), heater (11), head (9), mould compositions such as (10).
The operation principle (see figure 1): add material 1 by charge door 1 (4), add material 2 by charge door 2 (5), plasticizing system in material 1 enters by the through slot on the external screw rod (6), material 2 is directly included interior plasticizing system in.External screw rod is the rotation plastifying material under transmission device (3) drives, and material is passed through head (9) extrusion molding.Inner screw (7) is the rotation plastifying material under hydraulic motor (1) drives, and inner screw retreats under the back pressure effect simultaneously, up to the plastics capacity that reaches regulation (extrusion molding is simultaneously finished).Then, external screw rod stops the rotation, and inner screw fast moving forward under transmission device (3) drives is injected mould with material.Finish a molding cycle.Repeat this forming process, but the continuous system product.
