Embodiment Construction

[0010] Such as figure 1 and figure 2 As shown, the recliner handle injection mold includes a lower mold 1 and a runner 4 , and the lower mold 1 is provided with a cavity 2 for installing a metal insert 7 .

[0011] In the prior art, when the angle adjuster handle is injected, the metal insert 7 is installed in the cavity of the lower mold 1 with an interference fit, and the runner 4 is arranged at the lower end of the side wall of the arc section 21 of the cavity 2 In this way, after a period of use, the interference between the metal insert 7 and the cavity 2 will gradually decrease, and then the metal insert 7 installed in the cavity 2 will become loose, and at the same time, under the impact of injection molding , the thickness of the plastic layer 6 of the cast recliner handle is not very uniform, so that the metal insert 7 will leak to varying degrees, and the brightness consistency of the product is difficult to guarantee. At the same time, the paint surface of the met...

Abstract

The invention discloses an angle regulator handle injection mold. The angle regulator handle injection mold comprises a mold lower die and a pouring channel, wherein the mold lower die is provided with a cavity which is used for mounting a metal insert. The angle regulator handle injection mold is characterized in that the bottom surface of the cavity is provided with a fixing mechanism which is used for fixing the metal insert; a rubber inlet in a contact part between the pouring channel and the cavity is formed in the upper end of the arc section side wall of the cavity. Through the angle regulator handle injection mold, the problem of leakage of the metal insert is solved; the metal insert is stably fixed in the cavity; the qualified rate of the angle regulator handle product is increased to be greater than 85%; meanwhile, the metal insert is not coated manually after the metal insert is processed, so that a great amount of manpower and material resources are saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a processing workpiece of a handle of an automobile seat height adjuster, in particular to an injection mold for a handle of a recliner. Background technique [0002] During the use of the recliner handle, it is necessary to ensure the strength as well as the unity of the style and feel of the appearance and interior parts. The recliner handle is produced by injection molding of metal inserts, and the metal inserts are placed in the mold Inside the cavity, injection molding is performed after the mold is closed. However, when the B515 height adjustment handle assembly mold was tested for mold verification, the placed metal inserts were not firmly fixed in the mold cavity, resulting in uneven thickness of the injection material at the front of the product, causing varying degrees of leakage of the metal inserts, and the brightness of the product Consistency is difficult to guarantee, and at the same time, the paint surface of t...
