No machine contains all three methods at the same time
[0007] 2. In the structure of the invention shown in the above-mentioned patent announcement number CN 201863371 U, when the machine operates in the "rotary shaft type" (that is, the "clear double-color rotary core type" described in this manual), the turntable needs to rotate
Due to the heavy weight and large moment of inertia of the turntable, additional energy needs to be consumed, and the control of the rotation is not flexible enough
[0008] 3. The invention shown in the patent announcement number CN 202016159 U only includes one method of "clear double-color turntable type"

Embodiment Construction
[0022] Below in conjunction with accompanying drawing, the present invention is described in further detail respectively according to three different modes of operation with preferred embodiment:
[0023] 1. The two-color injection molding machine of the present invention operates in the mode of "clear two-color rotary core":
[0024] Such as figure 2 As shown, the two-color injection molding machine of the present invention includes a moving platen 1 on which a turntable bottom plate 4 is fixedly installed, and a servo motor 2 and a reducer 3 are installed on the upper end of the turntable bottom plate 4 . A rotary sleeve 14 is arranged at the center of the movable template, and the rotary sleeve 14 is fixedly connected with the rotating disk 9 . Rotary disk 9 right side upper ends are fixedly installed drive shaft support 7, and drive shaft support 7 links to each other with the right end of drive shaft 5, and the left end of drive shaft 5 is fixed on the speed reducer 3, ...

The invention relates to double colored injection molding machine capable of producing double colored products in rotating core, rotating disc and color blending ways, and an implementation method thereof. When the double colored injection molding machine is operated in a rotating core way, a servo motor fixedly arranged at the upper end of a rotating disc bottom plate rotates to drive a mold core to rotate through a decelerating machine, a drive shaft, a synchronous belt drive wheel, a synchronous belt, a synchronous belt driven wheel, a driven wheel gland and a rotating core connecting rod, and meanwhile, a hydraulic oil at an oil distribution sleeve is controlled to push the mold core to make jacking-in or jacking-out action to realize the change of a mold cavity. When the double colored injection molding machine is operated in a rotating disc way, the servo motor rotates to drive a rotating disc to rotate through a decelerating machine, a drive gear, an intermediate gear and a large gear ring to realize the change of the mold cavity. When the double colored injection molding machine is operated in a color blending way, a movable template part has a rotating disc type structure, and a color blender is arranged on a code mold surface of a fixed template. Two strands of sizing materials jet from two sizing melting cylinders are controlled by a spool and then are converged into one strand by one end of the color blender to be injected into the mold through a jet nozzle at the other end of the color blender.
Description
technical field [0001] The invention relates to a two-color injection molding machine and its realization method, in particular to a two-color injection molding machine capable of producing products in three ways: clear two-color rotary core type, clear two-color turntable type, and mixed colors. Background technique [0002] 1. The existing two-color injection molding machines are classified according to the way and effect of mixing the two colors, mainly in the following categories: [0003] 1. Clear two-color rotary core type: This type of machine is equipped with an auxiliary template on the movable template, and a pair of mold cores with two cavities are installed on the auxiliary template, and the rotation of the mold core is realized by the rotation of the rotating shaft to complete the change of the mold cavity. It mainly produces clear and two-color products with clear color boundaries. This type of machine has two nozzles, which pass through the fixed platen and ...
