The double-barrel injection system is composed of two independent barrels that store and heat two plastic raw materials of different colors or characteristics respectively, and is equipped with an injection cylinder and a nozzle to inject the raw materials into the molding mold. The molding mold of the two-color foaming molding machine is mainly composed of an upper mold and a lower mold. The upper and lower molds can be controlled to close by a hydraulic cylinder. The basic frame of the molding mold is usually made of high-strength steel to ensure that it can withstand high pressure and temperature during the molding process.

The limiting component 54 includes a limiting strip, which is fixed Installed on the rear side wall of the inner cavity of the installation frame 52, the back of the two sensing blocks 53 are provided with limiting grooves, and the outer surfaces of the limiting strips are respectively slidably connected to the inner walls of the two limiting grooves, so that the sensing blocks 53 are limited to moving left and right in a straight line along the outer surface of the limiting strip. The front of the two sensing blocks 53 is fixedly installed with a connecting frame 55, and the interior of the two connecting frames 55 is fixedly connected with a connecting piece 56 for driving the split side mold 51, and the opposite sides of the two connecting pieces 56 are respectively fixedly connected to the opposite sides of the two split side molds 51.

[0022] Among them, the two connecting frames 55 both include a rectangular frame and a displacement sensor. The displacement sensor is fixedly installed on the rear side wall of the inner cavity of the rectangular frame. The rectangular frame is fixedly connected to the front of the sensing block 53. One end of the connecting piece 56 passes through the rectangular frame and is fixedly connected to the inner wall of the rectangular frame, so that the sensing block 53 and the connecting piece 56 can be connected through the connecting frame 55, so that when the sensing block 53 moves, it can drive the split side mold 51 on the same side to move synchronously.

[0023] By adopting the above technical solution, it is possible to utilize the control structure to drive the two sensing blocks 53 to move to the opposite side, and then the moving sensing blocks 53 drive the connecting frame 55 to move synchronously, so that the moving connecting frame 55 drives the split side mold 51 on the same side to slide through the connecting piece 56, and then control the two split side molds 51 to slide to the opposite sides respectively, thereby completely opening the molding mold, and the staff can remove the molded workpiece from the lower mold 2 completely and quickly through the space behind the moving split side mold 51.
