[0025] Please refer to Figures 1 to 3 As shown, this preferred embodiment provides a positioning and pressure maintaining mechanism 1 for a passenger car interior trim part mold. Among them, a surface support seat 3 for supporting the interior trim part product 4 is provided on the interior trim part mold 2, and a process hole position 41 is provided on the interior trim part product 4.

[0026] The positioning and pressure maintaining mechanism 1 for the passenger car interior trim part mold includes a positioning seat 11 provided on the surface support seat 3. A boss 12 is provided on the positioning seat 11. The outer shape of the boss 12 is designed to be conformable to the contour of the process hole position 41. Two pressing blocks 13 are provided on the boss 12. The two pressing blocks 13 are symmetrically arranged and are respectively rotatably connected to the boss 12. The two pressing blocks 13 are driven by a driving component to rotate synchronously and reversely, so as to switch between a tightened state and an opened state.

[0027] In the tightened state, the two pressing blocks 13 and the boss 12 can freely pass through the process hole position 41;

[0028] In the open state, the two pressing blocks 13 respectively extend out of the side surface of the boss 12 and press against the surface of the interior trim product 4.

[0029] Thus, the positioning and pressure-holding mechanism 1 for the passenger car interior trim mold is installed on the surface support seat 3 of the existing mold. By the cooperation of the boss 12 and the process hole position 41, the positioning accuracy of the interior trim product 4 is further ensured. By the two pressing blocks 13 pressing against the interior trim product 4, the position stability of the interior trim product 4 is further ensured, so as to realize the simultaneous positioning and pressure-holding of the interior trim product 4, improve the accuracy and stability in the processing and manufacturing process of the interior trim product 4, and be more conducive to the molding of the interior trim product 4.

[0030] Specifically, the driving assembly here includes a driving cylinder 14 and a transmission rack 15. The transmission rack 15 passes through the positioning seat 11 and is located between the two pressing blocks 13. Gear parts 16 cooperating with the transmission rack 15 are respectively arranged on the two pressing blocks 13. The output rod of the driving cylinder 14 is connected to one end of the transmission rack 15, so as to drive the axial telescopic movement of the transmission rack 15 through the driving cylinder 14, driving the two pressing blocks 13 to perform the tightening or opening action.

[0031] Furthermore, a through hole for limiting and guiding the transmission rack 15 is opened on the positioning seat 11, ensuring the accurate repeated movement of the transmission rack 15, and further ensuring the reliable cooperation between the transmission rack 15 and the two gear parts 16.

[0032] Furthermore, the cylinder body of the driving cylinder 14 is fixed to the back surface of the surface support seat 3. The output rod of the driving cylinder 14 is threadedly connected to the end of the transmission rack 15, and the magnitude of the pressure for pressing the interior trim product 4 can be changed by selecting the cylinder diameter of the cylinder or adjusting the air pressure, meeting the usage requirements.

[0033] In addition, the meshing teeth of the two gear parts 16 and the transmission rack 15 are key stress-bearing components, and the hardness can be enhanced through tooth surface quenching treatment, improving the service life of the positioning and pressure-holding mechanism 1 for the passenger car interior trim mold.

[0034] Particularly, a groove 31 is provided on the surface support seat 3. The positioning seat 11 is embedded in the groove 31, and the non-boss surface of the positioning seat 11 is flush with the front surface of the surface support seat 3. The height of the boss 12 is greater than the thickness of the interior trim product 4, so as to ensure that the positioning of the original interior trim product 4 will not be affected after the positioning seat 11 is installed on the surface support seat 3.

[0035] Furthermore, the pressing surface of the pressing block 13 is designed to be conformable to the surface of the interior trim product 4, avoiding damage to the surface of the interior trim product 4 and making the pressing effect better.

[0036] Particularly, an installation groove 17 is formed in the boss 12, and two pin shafts 18 are inserted through the installation groove 17. The two pressing blocks 13 are respectively arranged in the installation groove 17, and the two pin shafts 18 respectively serve as the rotation centers of the two pressing blocks 13, making the structure of the positioning seat 11 more reasonable and compact.

[0037] Operation process:

[0038] 1) Place the interior trim product 4 on the interior trim mold 2, and form a stable support for the interior trim product 4 by the surface support seat 3;

[0039] 2) Align the boss 12 of the positioning seat 11 accurately with the process hole position 41 of the interior trim product 4, and the boss 12 and the two pressing blocks 13 in the tightened state pass through the process hole position 41 to achieve the positioning function;

[0040] 3) The driving cylinder 14 controls the driving rack 15 to drive the two pressing blocks 13 to open, so that the pressing surfaces of the pressing blocks 13 act on the surface of the interior trim product 4 to achieve the pressure maintaining function.

[0041] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
