Problems solved by technology
[0004] In the process of realizing the present application, the inventors found that there are at least the following problems in this technology: After the existing molds are used for injection molding such sleeves, the mold opening is generally based on the product centerline and horizontal level, but the surface of the product, especially There will be a parting line on the surface of the waterproof lip. As the mold wears, the parting line will become thicker and thicker. When the waterproof lip touches the rib on the frame, the parting line will The gap between the waterproof lip and the rib is enlarged, and rainwater can easily enter the connecting groove through the gap between the waterproof lip and the rib, which will cause the waterproof function of the product to fail

The invention relates to an automobile tail door threading sleeve mold structure, and relates to the technical field of molds, the automobile tail door threading sleeve mold structure comprises an upper mold and a lower mold, the lower mold is detachably connected with a cross beam, the side wall of the cross beam is fixedly provided with a mold core, the surface of the lower mold is provided with an injection molding groove for the mold core to insert, the side wall of the cross beam is movably connected with a molding ring, and the molding ring is fixedly connected with the cross beam. The mold core is sleeved with the forming ring, and a placement groove allowing the forming ring to be inserted therein is formed in the bottom wall of the injection molding groove. The waterproof structure has the advantages that the influence of the parting line on the waterproof performance of the product is reduced, and the waterproof effect of the product is improved.
Description
technical field [0001] The invention relates to the technical field of molds, in particular to a mold structure for threading sleeves of automobile tailgates. Background technique [0002] At present, molds are various molds and tools used in the industry to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping, etc. The door strut is sleeved with a sleeve, and the rubber sleeve can protect the tailgate strut. [0003] A casing is designed in the related art, refer to figure 1 , which includes a pipe body 8, the surface of the pipe body 8 is provided with a connecting groove 81, the connecting groove 81 is arranged along the circumferential direction of the pipe body 8, and the inner side wall of the connecting groove 81 is provided with a waterproof lip 82 along its circumferential direction. The lip 82 and the pipe body 8 are integrally formed; after the pipe body 8 is sleeved on the tailgate strut, ...
