[0002] With the rapid development of the automotive industry, sunroofs, as a crucial component of automobiles, have attracted widespread attention for their PU hemming mold technology for glass and iron components. During hemming mold development, a rubber plug is required to cover the exposed iron components connecting the finished hemming product to the sunroof's motion mechanism. Currently, the rubber plugs used in the industry are single-sided, hydraulically clamped, and are flush against the product's adhesive surface. This not only affects the aesthetics of the finished product, but also hinders precise positioning of the iron components and wears the plug due to tensile forces during demolding. This increases the risk of rubber plug wear and requires frequent replacement, resulting in low production efficiency and wasted costs. Utility Model Content

The fixed block 9 and the mounting seat 3 are both fixedly installed in the lower template 16 of the mold. The middle part of the rocker bar 8 is connected to the fixed block 9 through a rotating shaft. An opening is provided at the top of the mounting seat 3, and the edging iron piece 1 is arranged in the mounting seat 3 through the opening. Glue plugs 2 are provided on both sides of the edging iron piece 1 inside the mounting seat 3, and clamping blocks 4 are provided on both sides of the glue plug 2 inside the mounting seat 3. The lever force of the two groups of clamping blocks 4 acts simultaneously, and the two sides of the glue plug 2 are evenly pressed. A locking block 6 is provided below the clamping block 4 inside the mounting seat 3, and the locking block 6 abuts against one end of the rocker bar 8.

[0024] The pressure rod 10 is movably arranged in the lower template 16 of the mold through the upper and lower parts. A limit cup head 17 is provided at the bottom of the pressure rod 10 outside the lower template 16. The pressure rod 10 and the mounting seat 3 are both vertically arranged in the lower template 16. The top of the pressure rod 10 is against the upper template 15 of the mold. The driving force of the locking block 6 is the clamping force generated by the upper template 15 of the mold and is transmitted to the locking block 6 through the pressure rod 10 and the rocker rod 8, rather than the cylinder driving force.

[0025] Two sets of plugs 12 are vertically arranged above both ends of the rocker bar 8, and the tops of the two sets of plugs 12 are in contact with the locking block 6 and the limit cup head 17 respectively.

[0026] A first return spring 11 is provided below one end of the rocker bar 8 near the pressure rod 10. The bottom of the first return spring 11 abuts against a limit seat 18, and the top abuts against the rocker bar 8. The limit seat 18 is provided in the lower template 16 of the mold.

[0027] A cover plate 7 is also installed on the upper part of the mounting seat 3 by bolts. After the cover plate 7 and the mounting seat 3 are installed by bolts, they form an integral component with the internal rubber plug 2, clamping block 4, second return spring 5, and locking block 6. The separate design of the cover plate 7 and the mounting seat 3 can facilitate the replacement of the rubber plug 2.

[0028] The inner sides of the upper parts of the two groups of clamping blocks 4 are against the outer sides of the rubber plug 2. The middle part of each group of clamping blocks 4 is rotatably connected to the inside of the mounting seat 3 through a rotating shaft. The bottoms of the two groups of clamping blocks 4 are against the top of the locking block 6.

[0029] A slot 13 is provided at the top of the locking block 6, and a second return spring 5 is arranged in the slot 13. A fixed seat 14 is provided inside the mounting seat 3 between the clamping block 4. The top of the second return spring 5 is connected to the fixed seat 14, and the locking block 6 slides up and down along the internal limit of the mounting seat 3.

[0030] The bottom of the mounting seat 3 is also provided with an opening, and the top head 12 at one end of the rocker rod 8 passes through the opening at the bottom of the mounting seat 3 and abuts against the locking block 6. The inner diameter of the opening at the bottom of the mounting seat 3 is larger than the outer diameter of the top head 12.

[0031] like Figure 3 As shown, the rubber plug 2 is a rectangular parallelepiped as a whole and is clamped inside the mounting seat 3 . An opening is provided in the middle of the rubber plug 2 , and one end of the edging iron piece 1 passes through the opening in the middle of the rubber plug 2 .

[0032] The working principle of this utility model is:

[0033] When closing the mold, the upper template 15 presses the pressure rod 10 and transmits the force to the rocker rod 8. The other end of the rocker rod 8 presses the locking block 6 and rises synchronously. The locking block 6 slides into the interval between the two clamping blocks 4. The other ends of the two clamping blocks 4 are retracted and clamped under the action of the lever, and the glue plug 2 is clamped synchronously to realize the glue sealing function of the edging iron piece 1.

[0034] When the mold is opened, the upper mold plate 15 rises and leaves the pressure rod 10. Due to the action of the first return spring 11, the other end of the rocker arm will drop, and the second return spring 5 will push the locking block 6 to slide away from the two clamping blocks 4. The two clamping blocks 4 are reset under the action of the self-expansion elastic force of the rubber plug 2.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions should also be deemed to fall within the protection scope of the technical solution of the present invention.
