Description
Technical field
The utility model relates to a kind of micro-foaming and forming apparatus of ultrasonic control, belongs to micro-foamed polymer material technical field.
Background technology
Micro-foamed plastic is a kind of new structure functional material growing up for nearly 30 years, refer to a kind of cell diameter at 0.1～100 μ m(cell diameter than the little hundred times of regular-type foam plastics) reduce by 5%～95% Novel engineering structural plastic before scope, the comparable foaming of density of material.First the basic conception of micro-foaming put forward in 1981 by the researcher of the Massachusetts Institute of Technology, its design philosophy is that the bubble that is less than the critical crack size of polymeric material by preparation strengthens, toughening polymer material, to reduce density of material, lightening material weight, not only reduce material cost but also can put forward high performance object thereby reach.
At present, the process of preparing micro-polymeric material is mainly Physical and chemical method, wherein the associated core technology of the physical foaming method take supercritical gas as source of the gas is covered by foreign patent, and the core technology that has China's independent intellectual property right along this path exploitation has more technology barriers.And chemical method is to utilize regular injection machine equipment, by by after CBA (as AC blowing agent) and polymeric material melting mixing, adopt the processes such as low pressure (shorting), high pressure (twice-die-opening) or double-component injection to prepare micropore foamed polymer material and goods.Than the domestic and international Physical of studying already maturation and formed local sizable application in actual production, chemical method preparation technology is relatively simple and easy, equipment is simple, equipment investment is few, thereby the core technology that has China's independent intellectual property right in this field exploitation just seems very necessary.But chemical method injection is prepared capillary copolymer material and is also had technically many deficiencies, as foaming action process, foam structure etc. are all difficult to control etc.
Summary of the invention
The technical problems to be solved in the utility model: micro-foaming and forming apparatus that a kind of ultrasonic control is provided, with overcome when existing chemical method is produced micro-foamed polymer material, exist because polymeric material diffusion rate, different solubility cause polymeric material abscess-size inhomogeneous, the problem that comprehensive mechanical property is not high.
The technical solution of the utility model:
A kind of micro-foaming and forming apparatus of ultrasonic control, comprise fixed half and moving half, piston modules is positioned at dynamic model, with cover half composition die cavity, in dynamic model, is provided with heating tube around die cavity, in cover half, be provided with running channel, in fixed half and moving half, be respectively equipped with cooling water cavity, in described die cavity, be provided with Vltrasonic device, this Vltrasonic device comprises ultrasonic transducer and supersonic generator, ultrasonic transducer is connected with supersonic generator, and ultrasonic transducer is fixed on surface of mould cavity.
Above-mentioned ultrasonic transducer is fixed on die cavity by the cylindrical hole on dynamic model.
The utility model principle: micro-foamed polymer material be dispersed in gas phase in resin material matrix in resin matrix nucleation, form after growing up, be shaped into abscess, and in molten resin, the solubility of gas is subject to the impact of melt ambient vibration frequency obvious.Vibration frequency difference in micro-foam device die cavity, gas in resin flowing transport speed and the final abscess-size uniformity forming also thereupon different, thereby can control solubility and the diffusion velocity of gas in resin melt by the vibration frequency that regulates Foamex melt surrounding environment, realize the uniformity of abscess-size, to improve the comprehensive mechanical property of micro-foamed polymer material.
The beneficial effects of the utility model:
The utility model by installing Vltrasonic device on foaming equipment, utilize ultrasonic vibration to control the foaming process of micro-foamed polymer material, compared with prior art, can effectively control diffusion rate and the solubility of gas at polymeric material, make the abscess-size of polymeric material even, thereby the comprehensive mechanical property that improves polymeric material, reaches and not only reduces material cost but also can put forward high performance object.This device can directly apply to normal injection machine, and transformation difficulty is little, input cost is low, is easy to apply.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
the specific embodiment:
Embodiment:
