[0002] As we all know, in the process of automobile development, OEMs often develop preliminary verification products, and the same is true for automobile interior parts. For example, as a kind of interior parts, the headliner products are mostly made using a wet two-step process, which requires the development and production of a molding mold and a bonding mold. However, the substrate mold and the bonding molding mold are exactly the same in product shape, and the main difference between the two is the difference in the mold gap, which is a fabric thickness.

[0003] Therefore, the existing canopy products have the following disadvantages when wet forming:

[0004] 1) Two molds need to be made, and the mold opening cost is high;

[0005] 2) Early trial production requires frequent mold replacement and problem rectification, resulting in a waste of trial production time and resources. Summary of the invention

When the gap adjustment block is in the first state, the clamping platform is pressed against the support platform after the upper mold and the lower mold are closed.

[0011] Particularly, the gap adjustment block is fixed on a movable plate, the movable plate is connected to the driving end of the driving device, the movable plate can be movably assembled on a mounting seat, and the mounting seat is fixed on a side surface of the supporting platform.

[0012] Particularly, a T-shaped slot is provided on the movable plate, and the driving device adopts a cylinder, and the end of the piston rod of the cylinder is connected to the T-shaped slot through a T-shaped connector.

[0013] Particularly, a slide groove is provided on the mounting seat, and the movable plate can be movably assembled in the slide groove.

[0014] In particular, a guide assembly is provided between the moving plate and the slide groove to improve the stability and accuracy of the moving plate.

[0015] In particular, the guide assembly includes limiting grooves opened on both sides of the slide groove, and limiting bosses are arranged on both sides of the movable plate to match the limiting grooves, and the limiting bosses are located in the limiting grooves.

[0016] The beneficial effect of the present invention is that compared with the prior art, a gap adjustment mechanism is added to the wet forming mold of the automobile interior decoration parts, and the forming and bonding processes can be completed by using a pair of molds through gap adjustment. It is not only compact in structure and ingenious in design, but also reduces the mold opening cost, improves work efficiency, and saves working hours. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0022] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood. It should be noted that when a component is referred to as "fixed to" another component, it can be directly on the other component or there can also be a central component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a central component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for illustrative purposes and are not intended to be the only implementation method. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by technicians in the technical field of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] See also Figures 1 to 4 As shown, in this embodiment, a wet forming mold for automobile interior decoration parts includes an upper mold 1 and a lower mold 2. Four sets of guide assemblies are arranged at the four corners of the upper mold 1 and the lower mold 2. The guide assemblies include a guide sleeve 3 arranged on the upper mold 1 and a guide column 4 arranged on the lower mold 2. A support platform 5 is arranged on one side of the guide column 4 on the lower mold 2, and a downwardly extending clamping platform 6 is arranged on the guide sleeve 3 of the upper mold 1 to cooperate with the support platform 5.

[0024] The sides of the support platform 5 are all equipped with gap adjustment mechanisms, which include a mounting seat 7, a cylinder 8, a movable plate 9 and a gap adjustment block 10. The mounting seat 7 can be detachably fixed to the side of the support platform 5 by fixing bolts. A cylinder mounting plate 11 is installed at the outer end of the mounting seat 7. The cylinder 8 is fixed on the cylinder mounting plate 11. A slide groove 12 is provided on the mounting seat 7. Limiting grooves 13 are correspondingly provided on both side surfaces of the slide groove 12. Limiting bosses 14 extend outwardly on both sides of the movable plate 9 in cooperation with the limiting grooves 13. The limiting bosses 14 are arranged in the limiting grooves 13. A T-slot 15 is provided on the movable plate 9. The end of the piston rod of the cylinder 8 is connected to the T-slot 15 through a T-connector 16. The extension and retraction of the piston rod of the cylinder 8 drives the movable plate 9 to reciprocate in the slide groove 12, and the gap adjustment block 10 is fixed to the end of the movable plate 9. The limiting groove 13 and the limiting boss 14 can ensure the movement accuracy of the gap adjustment block 10. During the product trial production process, the gap adjustment block 10 can be replaced according to the actual fabric fitting effect.

[0025] When producing the base material, the pneumatic mechanism retracts; when producing the fabric bonding, the pneumatic mechanism extends to increase the mold gap. The specific action process is:

[0026] When producing base materials, the cylinder 8 drives the gap adjustment block 10 to retract, the upper mold 1 is pressed down to close the mold, and the clamping platform 6 does not contact the gap adjustment block 10, so as to achieve the gap required for base material production. When producing fabrics, the cylinder 8 drives the gap adjustment block 10 to extend and push it flat to the support platform 5. The upper mold 1 is pressed down to close the mold, the clamping platform 6 contacts the gap adjustment block 10, and the gap adjustment block 10 and the support platform 5 support the mold gap to achieve the gap required for lamination production.
