Description

Technical Field

[0001] The utility model belongs to the technical field of injection molding machines and relates to a movable injection molding turret and an injection molding machine. Background Art

[0002] Currently, the mold industry is relatively weak in one-time injection molding of multi-color products.

[0003] For example, an invention patent with application number CN201710611392.9 discloses a three-color injection molding device and a molding method thereof, wherein the equipment includes a turntable and three injection molding units arranged on the outer circumference of the turntable, each injection molding unit includes an injection device, a mold clamping device, an injection mold and a station conversion device, the injection mold includes a middle mold assembly, the middle mold assembly includes a guide back plate, a guide block, a middle mold, and a transmission rod, and the station conversion device includes a middle mold fixing mechanism, an ejection mechanism, a conveying mechanism and a locking mechanism; in addition, the three-color molding method includes the following steps: one of the injection molding units molds the first color of the injection molded part, and the middle mold is connected to the injection molded part as a whole; the ejection mechanism separates the injection molded part from the fixed mold; the conveying mechanism drives the middle mold assembly to move along the guide rod toward the turntable; the locking mechanism fixes the middle mold assembly; the turntable drives the middle mold assembly to enter the next injection molding station; and the above steps are repeated until the injection of three colors is completed.
