Rotating disc adjusting device of double-colored plastic injection machine

Abstract

The invention discloses a rotating disc adjusting device of a double-colored plastic injection machine. The rotating disc adjusting device mainly comprises an independent rotating disc bottom plate and floating pistons, that is, the rotating disc adjusting device is formed by the multiple floating pistons embedded on the independent rotating disc bottom plate; the floating pistons are wrapped by floating piston cylinder barrels; the floating piston cylinder barrels are mounted on the independent rotating disc bottom plate, and the plane of the floating piston cylinder barrels is slightly lower than or parallel to the plane of the independent rotating disc bottom plate; space for laying pipelines is designed on the back surface of the independent rotating disc bottom plate, the groove plane is lower than the plane of the independent rotating disc bottom plate, the pipelines are input from the top of the independent rotating disc bottom plate, and normal assembly of the independent rotating disc bottom plate and a movable formwork is not hindered. The adjusting device can effectively solve the problem of side inclination of a rotating disc caused by gravity torque, and is simple in structure and convenient to mount; no complex structure exists outside, and the device is embedded in the independent rotating disc, so that normal mounting and use of other mechanisms cannot be influenced; the floating pistons are in surface contact with the independent rotating disc bottom plate, so that the frictional wear to the rotating disc can be reduced, and the service life of the independent rotating disc is prolonged.

Description

technical field [0001] The invention relates to the field of two-color injection molding machines used for injection molding, in particular to a turntable adjustment device of a two-color injection molding machine. Background technique [0002] With the development of modern industry, the two-color injection molding process is getting more and more attention in the plastic machine industry. Two-color injection molding process refers to the molding process of injecting two materials of different colors into the same plastic mold simultaneously or sequentially. For the two-color injection molding machine used in the two-color injection molding process, due to functional and structural reasons, the turntable inevitably has a roll problem after carrying the mold, and the roll of the turntable will cause scratches between the mold plate and the turntable. The unstable operation of the turntable will directly affect the matching accuracy of the mold clamping, the yield rate of th...

Problems solved by technology

For the two-color injection molding machine used in the two-color injection molding process, due to the functional structure, the turntable inevitably has a roll problem after carrying the mold, and the roll of the turntable will cause scratches between the mold plate and the turntable

The turntable is unstable, which will directly affect the matching accuracy of the mold clamping, the yield of the product and the safety of the operator, and it is also the main factor restricting the load-bearing capacity of the turntable
