[0006] Furthermore, the adjustment mechanism also includes a positioning plate arranged on the C-shaped seat body, and the movable plate can be moved back and forth and is arranged on the positioning plate.

[0007] Furthermore, the adjustment mechanism also includes a plurality of guide positioning members arranged between the positioning plate and the adjustment plate, the guide positioning members include two positioning holes relatively arranged on both sides of the movable plate and extending downward from the top surface of the adjustment plate to the positioning plate, and two positioning pins respectively arranged in the two positioning holes, the lower end of the positioning pin is connected to the positioning plate, and the upper end extends upward into the adjustment plate.

[0008] Furthermore, the adjustment mechanism also includes a mounting block disposed on the C-shaped seat body for mounting the positioning plate.

[0009] Furthermore, the adjustment mechanism also includes a limiter arranged on the side of the mounting block for limiting the moving distance of the movable plate, and the limiter includes a limiter block arranged on the side of the mounting block and a limiter bolt that can move forward and backward relative to the front end of the movable plate.

[0010] Furthermore, the adjustment mechanism also includes a mounting seat arranged on the side of the mounting block for mounting the adjustment cylinder.

[0013] A disc injection molding machine comprises a molding device.

[0014] From the above description of the utility model, it can be seen that compared with the prior art, the beneficial effects of the utility model are as follows: the present application cooperates between the disc, the mold station and the C-type seat, and defines the specific structure of the C-type seat, so that the adjustment mechanism for adjusting the height of the lower pressure block arranged on the C-type seat body cooperates with the upper pressure block of the C-type seat to change the gap between the lower pressure block and the mold station, which is beneficial to protect the disc from damage and improve the mold closing efficiency of the mold station. When the mold station enters between the upper pressure block and the lower pressure block with the disc, the movable plate is pushed forward by the adjustment cylinder to move the adjustment plate upward, thereby raising the lower pressure block, reducing the gap between the lower pressure block and the mold station, and preventing the disc from being deformed due to excessive pressure when the upper pressure block is pressed downward; after the mold station completes the injection, the movable plate is pushed backward by the adjustment cylinder to move the adjustment plate downward, thereby increasing the gap between the lower pressure block and the mold station, and ensuring the smooth rotation of the disc;

[0015] By setting a limiter on the side of the mounting block for limiting the moving distance of the movable plate, the forward position of the movable plate can be adjusted, thereby adjusting the lifting height of the adjustment plate. BRIEF DESCRIPTION OF THE DRAWINGS
