Air conditioner manifold branch air pipe production method and mold adopted by air conditioner manifold branch air pipe production method

Abstract

The invention discloses an air conditioner manifold branch air pipe production method. A fitting surface of a first blank (1) and a second blank (2) of an air conditioner manifold branch air pipe anda fitting surface of the second blank (2) and the first blank (1) of the air conditioner manifold branch air pipe are provided with long-strip-shaped grooves (3) correspondingly at first; the first blank (1) and / or the second blank (2) are / is provided with material overflow ports (5) communicating with the grooves; then a welding cavity (6) is formed in one side of an air conditioner manifold branch air pipe mold; and afterwards, during injection molding, a hot runner of the welding cavity is closed during primary injection molding. The mold adopted by the air conditioner manifold branch air pipe production method comprises the hot runner (8), a top plate (9), a first cavity (10) corresponding to the first blank (1), and a second cavity (11) corresponding to the second blank (2). The welding cavity (6) is formed in one side of the first cavity (10) or in on side of the second cavity (11). The welding cavity and the air conditioner manifold branch air pipe are identical in shape. A press-fitting mechanism is arranged on the periphery of the welding cavity (6) of the mold. The method and mold have the characteristics that intermediate transfer links can be omitted, the production yield is high, and the production cost is low.

Description

technical field [0001] The invention relates to a method for producing an air-conditioning branch manifold and a mold used therefor. Background technique [0002] The air-conditioning manifold of the vehicle is used for the air intake of the vehicle. Currently, the air-conditioning manifold is divided into two halves and then injection molded, and then the two parts are welded by ultrasonic welding. However, such a production method makes the air-conditioning manifold blank after injection molding easy to deform during the transfer process, resulting in the inability to perform subsequent ultrasonic welding, resulting in a high defective rate, and in the ultrasonic welding process, once the pressing is unstable , and the situation of virtual welding is prone to occur, so the overall yield is low and the manufacturing cost is high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an air-conditioning bronchial prod...
