1. Basic Principles of Two-color Module Design:
(1) Hard glue once and soft glue twice;
(2) transparent once and opaque twice;
(3) The plastics with high forming temperature are made once and the plastics with low forming temperature are made twice.
Above is the basic principle of making two-color die, otherwise the die will be made in vain; in addition, when sealing glue, try to rely on the breaking glue, rather than inserting the breaking glue, even if it is suggested that customers modify the product must rely on the breaking glue as far as possible;
2. Mould embryo guide sleeve must be symmetrical from top to bottom, from left to right, and from front to back.
3. The rear die should rotate 180 degrees and the front die should not move.
4. The distance between products must be based on the distance between the nozzles of injection moulding machines. The distance between the nozzles of some two-color injection moulding machines abroad is adjustable, some are not adjustable, and the distance between the nozzles of domestic ones is not adjustable.
5. Two separate ejection systems and two ejector sticks. The two products of the rear die are the same, and the thimble is the same. It is a rotational relationship. It must not be made into a translation relationship.
6. The ejector plate can only be reset by spring, not by screw, because the rear die has to rotate.
