Description

Technical Field

[0001] The utility model belongs to the technical field of mold injection equipment, and particularly relates to a mold structure for an anti-deformation sun visor skeleton. Background Art

[0002] At present, the forming of sun visor skeletons has methods such as injection molding, blow molding, foam molding, and lamination process; however, with the continuous development of industrial production, the requirements for the forming method of sun visor skeletons are also getting higher and higher; among them, due to problems such as low production efficiency of the blow molding method, low precision of the foam molding method, and overly complex lamination process, and currently, the injection molding method is mostly used for forming; however, the existing injection molding molds are prone to skeleton offset during use, resulting in a low qualified rate of skeleton injection molding and increasing production costs.

[0003] In order to solve the deficiencies of the existing technology, people have carried out long-term explorations and proposed various solutions. For example, a Chinese patent document discloses a mold [201520533098.7] for producing sun visor skeleton connectors, which includes a base for placing the sun visor skeleton, and a mold base for injection molding connectors to connect the two ends of the sun visor skeleton is provided on the base. The mold base includes a lower mold base fixedly connected to the base and used for placing the two ends of the sun visor skeleton, and an upper mold base slidably connected to the base. A cavity for accommodating the two ends of the sun visor skeleton is provided on the lower mold base; a positioning device for positioning the sun visor skeleton is provided on the base.

[0004] The above solution solves the problem of the existing sun visor skeleton offset in the mold to a certain extent, but this solution still has many deficiencies. For example, it only limits the sun visor skeleton through the first stop block and the second stop block, and the limiting effect is insufficient, resulting in the sun visor skeleton still being prone to offset, affecting the qualified rate of the sun visor skeleton.
