Abstract

The invention discloses a welding press-fit mold, and relates to the technical field of plastic welding. The welding press-fit mold comprises an upper mold and a lower mold; the upper mold includes an upper mold base; a fixed plate is fixedly connected under the upper mold base; at least two ultrasonic welding heads are uniformly and fixedly connected under the fixed plate and are used for connecting a first plastic part and a second plastic part in a welding manner; an upper pressing plate is connected below the upper mold base through elastic pieces, and is provided with through holes through which the ultrasonic welding heads can penetrate; two limiting bars are symmetrically arranged on two sides of the upper pressing plate; the lower mold includes a lower mold base and a lower template fixed above the lower mold base; and limiting grooves matched with the limiting bars are formed in two sides of the top of the lower template. According to the welding press-fit mold, accurate positioning and firm pressing are achieved, and the problem that plastic parts are easily misplaced during welding is effectively avoided; and meanwhile, the at least two ultrasonic welding heads are adopted to uniformly contact with the plastic parts, so that the multi-point welding of the plastic parts is realized, the production procedures are greatly simplified, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of plastic welding, in particular to a welding pressing mold. Background technique [0002] At present, most of the automotive interior parts are plastic parts. During the production process, it is often necessary to bond two or more parts together for use. However, due to the disadvantages of poor control of the amount of glue, heavy glue smell, and hazards to the health of drivers and passengers in the way of glue bonding, people are increasingly favoring the use of ultrasonic welding for production. Ultrasonic welding uses the vibration of the welding head to transmit ultrasonic waves to the plastic parts. Due to the high acoustic resistance of the two plastic parts, local high temperature is generated to melt the interface of the plastic parts. Under a certain pressure, the two plastic parts can be welded quickly and firmly. . However, due to the lack of limiting and pressing devices in existing ultras...
