Die for in-die injection molding assembling of air outlet blade and connecting rod

Abstract

The invention relates to the field of machines, in particular to a die for in-die injection molding assembling of an air outlet blade and a connecting rod. The die comprises a front die, a rear die, a first injection nozzle and a second injection nozzle. The die for in-die injection molding assembling of the air outlet blade and the connecting rod is characterized in that a front die is arranged above the rear die; a rotary core plate is embedded in the rear die, and the rotary core plate is in a reverse Z shape; the first injection nozzle and the second injection nozzle are arranged on the left side and the right side of the interior of the front die located above the rotary core plate correspondingly; a first rotary core plate sliding block is arranged at the position, located below the first injection nozzle, on the rotary core plate; a connecting rod injection molding product is arranged in the first rotary core plate sliding block; a second rotary core plate sliding block is arranged at the position, located below the second injection nozzle, on the rotary core plate; and a blade injection molding product is arranged in the second rotary core block sliding plate. Compared with the prior art, due to natural shrinkage of materials, an even gap is formed between a blade shaft and a connecting rod hole, the problems of vibration abnormal sounds and large operation force caused by matching of the shaft and the hole are effectively solved, the more comfortable operation hand feeling and a quiet environment in a vehicle are brought to a user.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a mold for in-mold injection assembly of air outlet blades and connecting rods. Background technique [0002] There are a large number of parts in the air outlet assembly. The parts of the same material in traditional mold injection molding need to be molded separately, resulting in a large number of parts and molds. Secondary operations often have warping deformation or shrinkage out of tolerance, and the product shaft hole size matching gap Problems such as abnormal noise and heavy operating force are prone to cause customer complaints. At the same time, the number of injection molding machines increases, the number of tooling increases, the space occupied by the site is large, and the assembly labor increases. Usually, human error in assembly will lead to quality defects, automatic production cannot be realized, and production efficiency is low. Contents of the invention [0003] In ...
