Problems solved by technology

However, such a production method makes the injection-molded air-conditioning manifold blanks easily deformed during the transfer process, resulting in the inability to perform subsequent ultrasonic welding, resulting in a high rate of defective products, and in the ultrasonic welding process, once the pressing is unstable , and it is prone to false welding, so the overall yield is low and the preparation cost is high

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as Figure 1~6 As shown, a blank structure in the production process of an air-conditioning branch manifold, which includes an air-conditioning branch manifold blank, is provided with a main air intake channel 10, a manifold channel 11 and a buffer chamber 12 on the air-conditioning branch manifold, and the buffer chamber 12 passes through The manifold channel 11 communicates with the main intake channel 10, and the main intake channel 10 and the manifold channel 11 have a "herringbone" shape structure, which can reduce the overall volume; the air-conditioning branch manifold blank is divided into the first blank 1 and the second blank. Blank 2, when the air-conditioning branch manifold blank is placed horizontally, is divided into the first blank 1 and the second blank 2 in the horizontal direction; the lower end surface of the fir...

Abstract

The invention discloses a blank structure used in the air-conditioner manifold production process. The blank structure comprises an air-conditioner manifold blank which is divided into a first blank body (1) and a second blank body (2). The lower end face of the first blank body (1) is attached to the upper end face of the second blank body (2). Strip-shaped grooves (3) are arranged on the face, attached to the second blank body (2), of the first blank body (1) and the face, attached to the first blank body (1), of the second blank body (2) correspondingly. The first blank body (1) and / or thesecond blank body (2) are / is provided with at least one input sprue (4) communicating with the grooves (3). The first blank body (1) and / or the second blank body (2) are / is provided with a plurality of overflow openings (5) communicating with the grooves (3). Compared with the prior art, the blank structure has the beneficial effects of omitting the middle transfer link of the air-conditioner manifold production, and being capable of increasing the production finished product rate and relatively low in production cost.

Description

technical field [0001] The invention relates to a blank structure in the production process of an air-conditioning branch manifold. 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 a blank structure in the production...
