Problems solved by technology

[0003] (1) Use two racks to reversely push the pinion behind the turntable to drive the turntable to rotate forward or reverse. The structure is complex, and the pinion bears a lot of load. When the mold is heavy, the pinion is easy to break
[0004] (2) The two racks and the fixed seat are sliding friction, and the gap will become larger after a period of use, causing the gap between the rack and the pinion to become larger, and there will be impact wear when the tooth surfaces mesh, and the service life is not long
[0005] (3) The positioning structure of the rack and pinion is complicated, which is very inconvenient for assembly and maintenance

Abstract

The invention relates to a multi-color injection molding machine. The multi-color injection molding machine comprises an adjusting mold plate, a moving mold plate and a fixed mold plate, wherein a mold and a rotating disc are fixedly arranged on the moving mold plate, the rotating disc is connected to the moving mold plate through a rotating shaft and a bearing, and a driving part is matched with the rotating disc for rotation. The multi-color injection molding machine disclosed by the invention has the advantages of reliable performances, convenience in installation and good transmission effect.

Description

technical field [0001] The invention relates to an injection molding machine, in particular to a novel gear-driven multi-color injection molding machine. Background technique [0002] With the improvement of living needs, people's aesthetic concept is increasing day by day. Plastic products containing more than two colors are widely used, and correspondingly, the requirements for injection machines for molding multi-color plastic products are also getting higher and higher. The molding method of multi-color plastic products has multiple machines: that is, there are multiple injection molding machines. The first one injects the first plastic (that is, the plastic of the first color), and after forming a semi-finished product, the semi-finished product is manually put into the second machine. The second plastic (that is, the plastic of the second color) is injected into the mold of the injection molding machine, and the injection of other colors is analogized by analogy. The...
