Ultrasonic plasticization flexible molding device and method with flow channel and controllable temperature filed

Abstract

The invention discloses an ultrasonic plasticization flexible molding device and method with a flow channel and a controllable temperature filed. The device comprises an upper mold plate and a lower mold plate; a first containing groove and a material hole which is matched with an external ultrasonic flexible punching head are formed in the upper mold plate; the first containing groove is internally provided with a first inlaying block, a first heating assembly for preheating the first inlaying block and a first miniature thermal electric couple for detecting the temperature of the first inlaying block; a second containing groove which corresponds to the first containing groove is formed in the lower mold plate; the second containing groove is internally provided with a second inlaying block, a second heating assembly for preheating the second inlaying block and a second miniature thermal electric couple for detecting the temperature of the second inlaying block; and the arc-shaped flow channel which is connected with the second containing groove is further formed in the lower mold plate. According to the ultrasonic plasticization flexible molding device and method with the flow channel and the controllable temperature filed, the macromolecular conformation change of a thermal melt body in the flowing process is avoided, a position at which defects are possibly generated and the varieties of the defects of a product are enabled to be visualized, the quality of the product is improved, a double-micro-surface structure can be machined, and the application prospects are wide.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of ultrasonic welding molds, in particular to a temperature field controllable ultrasonic plasticizing flexible molding device and method with flow channels. Background technique [0002] The conventional injection molding process is to heat up the machine to melt the molecular material, inject it into the mold cavity with high pressure, and obtain the desired shape and quality of the product after cooling and setting. This method needs to go through six stages of mold closing, glue injection, pressure holding, cooling, mold opening, and product removal. The process is complicated and the quality is not easy to control. The processing process involves many aspects such as mold design and manufacturing, raw material characteristics, molding process, and injection molding machine operation. Aspects of factors, and are closely related to processing environmental conditions, product coo...

AI Technical Summary

Problems solved by technology

[0003] 1. Ultrasonic plasticizing reaction time is extremely short, and at the same time, ultrasonic energy will attenuate when encountering medium barrier during longitudinal transmission, resulting in uneven forming temperature in each area of ​​micro parts, affecting surface quality and mechanical properties;

[0004] 2. The surface microstructure shape of the obtained micro-parts can be changed according to the needs, but it is limited to the single-layer surface, and the double-sided or multi-sided microstructure shape cannot be obtained on the surface of the micro-parts
