Abstract
The invention discloses an injection molding part based on ultrasonic waves. The injection molding part comprises an ultrasonic oscillator, a power source, a charging barrel, a hopper, a screw and a power system. The hopper is disposed on the charging barrel and communicated with the charging barrel. An extrusion cavity is formed in the charging barrel, a heating electric ring is arranged outside the charging barrel, the screw is disposed in the extrusion cavity and connected with the power system, the ultrasonic oscillator is disposed in the hopper and connected with the power source, and a heating electric ring is also arranged on the outer wall of the hopper. As for polymer high in viscosity, the injection molding part solves the problem that an extrusion cavity can not be filled with polymer high in viscosity easily, and accordingly raw material waste is severe.
Description
Technical field
The present invention relates to injection molding art, be specifically related to a kind of based on hyperacoustic injection moulding parts。
Background technology
The appearance of plastics industry can be traced to the source to 1862, and this year, Englishman Parkes put on display some little goods with the mold pressing of Parkesine material on an exhibition in London。Here it is the origin of injection molding technology。Nineteen twenty injection molding technology oneself start industrialization, but until nineteen twenty-six just occur in that the first batch of injection machine for processing plastics manufactured according to industrial standard in Germany。It is proposed again later and uses power-actuated injection machine, also invented, in Britain, the injection machine that compression aero-oleopneumatic drives, start to occur in that the development blank of injection molding technology。After World War II, polymer kind has had very big increase and has in succession put into industrialized production, just makes injection molding technology be able to rapid development。After 1970, along with the progress of science and technology, plastic is from civilian to industry developments such as industry, agricultural, national defence and traffic。Therefore, the requirement of quality of item is more and more higher, and injection-moulding device and technology are had higher requirement。Injection-moulding device and technology start to high-speed and high-efficiency, automatization, specialization, microminiaturization, the development of precise treatment aspect。
Summary of the invention
It is an object of the invention to provide based on hyperacoustic injection moulding parts, this Plasticized component is directed to the polymer that viscosity is high, solves the high polymer of viscosity and is not easily full of the problem that extruding cavity makes waste of raw materials serious。
The present invention is achieved through the following technical solutions:
Based on hyperacoustic injection moulding parts, including ultrasonic oscillator, power supply, include barrel, hopper, screw rod, dynamical system, hopper is arranged on barrel and connects with barrel, being provided with extruding cavity in barrel, barrel is outside equipped with and adds thermoelectricity circle, and screw rod is arranged in extruding cavity, screw rod is connected with dynamical system, ultrasonic oscillator is arranged in hopper, and ultrasonic oscillator is connected with power supply, hopper outer wall is also equipped with add thermoelectricity circle。
The present invention is when in use, raw material to be processed is joined in hopper, start power supply, ultrasonic oscillator is made to start working, raw material to be processed is carried out ultrasonic frequency processing, the raw material processed through ultrasonic frequency is sent in extruding cavity then through screw rod, screw rod extruded from the nozzle of barrel by raw material further。The mechanism of the present invention is in that: utilizes hyperacoustic frequency that the molecular link of raw material to be processed is carried out energy and interrupts, thus changing the viscosity of polymer to be processed, improving the mobility of polymer, making injection molding be more prone to quick。
The present invention is provided with at hopper place and adds thermoelectricity circle, polymer is first preheated, again through ultrasonic oscillator, change the apparent viscosity of lower polymer, it is capable of effectively flowing under low in calories, reducing in whole system required heat, therefore the present invention also has the effect reducing energy consumption, and temperature that namely need not be higher just can improve the rheological characteristic of polymer。
Ultrasonic oscillator includes oscillator stage, amplified signal level, power-amplifier stage, transducer, the outfan of oscillator stage is connected with the input of amplified signal level, the outfan of amplified signal level is connected with the input of power-amplifier stage, and the outfan of power-amplifier stage is connected with the input of transducer。Transducer is a kind of device that high-frequency ac electric energy can be converted into mechanical energy。If desired, it is possible to arrange chiller again and transducer is cooled down, in case stop machine device is overheated, and machine is caused loss。
Ultrasonic frequency adjusting apparatus it is also associated with between ultrasonic oscillator and power supply。Ultrasonic frequency adjusting apparatus can conveniently adjust the frequency of vibration of ultrasonic oscillator, to adapt to the demand of different polymer。
Screw front end is additionally provided with check ring。
Dynamical system is cylinder and motor, screw rod and cylinders, cylinder and motors。
The present invention compared with prior art, has such advantages as and beneficial effect:
Present invention is directed at the polymer that viscosity is high, solve the high polymer of viscosity and be not easily full of the problem that extruding cavity makes waste of raw materials serious。
