[0013] Beneficial effects

[0014] The utility model provides a seam sealing structure for an automobile lamp injection mold. Compared with the prior art, it has the following advantages:

[0015] (1) The automobile headlight injection mold uses a seam sealing structure. By starting the rotating motor, the rotating disk is driven to rotate. When the rotating disk rotates, the elastic paddle is driven to rotate. During the rotation, the elastic paddle moves the paddle, so that the transmission gear rotates to the inside of the tooth groove, and then the transmission gear rotates 180 degrees. The rotation of the transmission gear drives the transmission rod, the connecting column and the mold table to rotate synchronously, so that the positions of the two groups of lower templates are interchanged. By providing a rotating mechanism, the positions of the two groups of lower templates can be quickly switched under the drive of the rotating motor, so that the injection-molded automobile headlight mold can be quickly removed. At the same time, during the demolding process, the subsequent injection molding operation is not affected, thereby improving work efficiency.

[0016] (2) The automobile headlight injection mold uses a joint sealing structure. By starting the sealing motor, the rotating disk and the arc block are driven to rotate synchronously. When the arc block rotates, it is connected with the linkage block at the bottom of the linkage plate, so that the linkage block, linkage plate, lifting plate and sealing plate slide upward synchronously. The linkage plate slides on the surface of the linkage rod, so that the linkage spring is stretched, and the sealing plate slides inside the lower template. By providing a sealing component, the sealing plate is driven by the sealing motor to slide to the inside of the sealing groove, thereby squeezing the sealing strip set in the sealing groove, thereby improving the sealing of the joint between the two sets of mold plates.

By providing a rotating mechanism 3 and utilizing the driving force of the rotating motor 311, the positions of the two groups of lower templates 5 can be quickly switched, thereby facilitating the rapid removal of the injection-molded automobile lamp mold.

The linkage plate 62 slides on the surface of the linkage rod 61, so that the linkage spring 64 is stretched, and the sealing plate 325 slides inside the lower template 5. By providing a sealing assembly 32 and driving the sealing motor 321, the sealing plate 325 slides to the inside of the sealing groove 24, thereby squeezing the sealing strip provided in the sealing groove 24, thereby improving the sealing of the joint between the two sets of mold plates.

After the automobile lamp is injection-molded, the upper template 23 is reset. Subsequently, the rotating motor 311 is started to drive the rotating disk 312 to rotate. The rotating disk 312 drives the elastic paddle 315 to rotate during rotation. The elastic paddle 315 toggles the paddle 43 during the rotation, so that the transmission gear 42 rotates to the inside of the tooth groove 313, and then the transmission gear 42 rotates 180°. The rotation of the transmission gear 42 drives the transmission rod 41, the connecting column 316 and the mold table 9 to rotate synchronously, so that the positions of the two groups of lower templates 5 are interchanged, so as to facilitate the subsequent automobile lamp injection molding operation. At the same time, by starting the ejection cylinder 7, the ejector rod 8 is driven to slide upward, and the injection-molded automobile lamp mold is ejected out of the mold groove by the ejector rod 8 for the collection operation.
