Abstract

The invention discloses a novel ultrasonic plasticizing forming device. The device comprises a movable mold device, a mold core, an ultrasonic plasticizing head, a fixed mold device, a feeding device and a material returning device, wherein the movable mold device is fixed on a workbench and is used for placing a plasticized polymer; the mold core is arranged in the movable mold device, and the outward end face of the mold core is provided with a mold cavity; the ultrasonic plasticizing head is arranged above the movable mold device and covers the mold core, and the ultrasonic plasticizing head is connected with an external ultrasonic generator; the fixed mold device is arranged outside the ultrasonic plasticizing head and is attached to the movable mold device; the feeding device is installed on the workbench and extends into the movable mold device to push the polymer to move; and the material returning device is installed on the workbench, penetrates through the movable mold device and is connected with the mold core, and a machined polymer product in the mold core is ejected out. According to the device, the problem of incomplete injection caused by high polymer viscosity of ultra-thin and micro-structure products can be solved.

Description

technical field [0001] The invention relates to the technical field of ultrasonic manufacturing, in particular to a novel ultrasonic plasticizing molding device and a control method. Background technique [0002] At present, polymer micro-parts are widely used in various fields such as electronic communication and aerospace, and micro-injection molding technology has become the focus of researchers because of its low cost and convenient processing. Molding technology also has problems such as filling difficulties and material waste. [0003] "Ultrasonic plasticizing" technology came into being. There are two production modes of ultrasonic plasticizing technology, one is "ultrasonic plasticizing head plasticizing and injecting" mode, which will lead to severe ultrasonic plasticizing head and plasticizing cavity. friction, causing the ultrasonic plasticizing head and plasticizing cavity to wear, and the other is the "ultrasonic plasticizing head plasticizing, feeding push rod...
