[0008] In the aforementioned automotive headlight dual-color mask injection mold fixed mold spring block sealing mechanism, one end of the support leg is connected to the front plate. Electric cylinders are installed at the center of the front plate and the center of the rear plate. The electric cylinders are commercially available devices known to those skilled in the art. Here, we are simply using them without making any structural or functional improvements, and we will not elaborate further.

[0009] In the aforementioned automotive headlight dual-color mask injection mold fixed mold spring block sealing mechanism, a top plate is provided on one side of the first front mold base and one side of the second front mold base. A pouring port is provided at the center of the top plate, and the output end of the electric cylinder is connected to one side of the top plate through a push rod.

[0010] In the aforementioned automotive headlight dual-color mask injection mold fixed mold spring block sealing mechanism, both sides of the rotating seat are provided with base plates, and one side of the rear mold base and the second rear mold base are connected to the base plates.

[0011] Compared with the prior art, the advantages of the sealing mechanism of the fixed mold spring block of the dual-color mask injection mold for automotive headlights of this utility model are:

[0012] This application features a rotatable rotating seat inside the support leg. The rotating seat is supported and rotated by a top pin. A rear mold base 1 and a rear mold base 2 are mounted on the side of the rotating seat via a base plate. The rear mold base 1 and the front mold base 1 cooperate with each other. After the mold is closed, the first injection molding is performed. The rotating seat drives the rear mold base 1 to rotate horizontally 180 degrees and switch with another front mold for the second injection molding. In this way, after the first injection molding, the product does not need to be demolded. It can be directly rotated for the second injection molding, which can effectively avoid problems such as embossing, dents, uneven sealing and flash caused by product deformation, and greatly improve production efficiency.
