Ultrasonic welding mould

Abstract

The invention discloses an ultrasonic welding mould. The ultrasonic welding mould is characterized in that a positioning seat is provided with evenly-distributed threaded holes, a positioning module is fixed in threaded holes of a base through bolts, a groove used for fixing a door plate is formed in a positioning module, a welding module assembly is further arranged at the position of the plane of the groove, and the welding module assembly comprises a heat conduction copper column inserted into the groove; a bending plate is arranged below the heat conduction copper column, a heat dissipation block is further arranged below the bending plate, and a heat conduction cover is connected into a threaded groove in the lower portion of the positioning module in a threaded mode; and rectangulargrooves are formed below the positioning seat, heat exchange fins are arranged in the rectangular grooves, and a central rectangular groove is formed in the center of the bottom of the positioning seat. The ultrasonic welding mould has the advantages that a convex edge and a positioning block ensure that the positioning reference of the welding procedure is more accurate, the structure of the positioning seat ensures that the structure of a heat dissipation part is consistent even if the appearance structure of the door plate is changed, and a central heat dissipation area and an edge heat dissipation areas are adopted, so that the heat dissipation area is larger, and meanwhile heat dissipation is more uniform.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a welding device for a car door panel. Background technique [0002] Ultrasonic welding is a technology commonly used in mechanical processing. At the same time, ultrasonic welding will generate huge heat for the welded objects, and the welding requirements for the welded parts on the car door panel are even stricter. The previous working method is to process the parts that need to be welded sequentially. , this welding method increases the process and processing time, and at the same time, what is more serious is that the inconsistency of each welding positioning reference leads to the failure of the yield to meet the requirements, and if multiple parts on the door panel are welded at the same time, the door panel will be concentrated due to the characteristics of ultrasonic welding Heating also affects the yield, so the prior art lacks a high-precision ultrasonic welding mo...
