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-foamed polymer 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 the micro-foamed polymer material of chemical method injection preparation also exists many deficiencies technically, for example expansion type cavity temperature is wayward, thereby can impact the foaming quality of micro-foamed polymer material.
Summary of the invention
The technical problems to be solved in the utility model: provide a kind of injection molding cavity temperature controlled micro-foam device, can be by the temperature of resin melt in cooling fluid control die cavity, micro-foamed polymer material foaming process gas is grown up and obtain Effective Regulation, obtain more satisfactory micro-foamed polymer material, improve foaming product surface quality, to overcome the deficiencies in the prior art simultaneously.
The technical solution of the utility model:
Micro-foam device that a kind of injection molding cavity temperature is controlled, comprise fixed half and moving half, piston modules is positioned at dynamic model, with cover half composition die cavity, in dynamic model, be 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 sap cavity, in described cooling sap cavity, be provided with temperature sensor, be respectively equipped with electromagnetic valve at water inlet pipe and the outlet pipe place of cooling sap cavity, temperature sensor and electromagnetic valve are all electrically connected with controller.
Above-mentioned temperature sensor is fixed in cooling sap cavity by the hole on cooling sap cavity wall.
In aforesaid die cavity, be also provided with pressure sensor.
Aforesaid pressure sensor is fixed in die cavity by the cylindrical hole on dynamic model, and pressure sensor is electrically connected with controller.
The beneficial effects of the utility model:
Compared with prior art, the utility model is by mounting temperature sensor in the cooling sap cavity of micro-foam device, at the inlet tube and outlet tube of cooling sap cavity, electromagnetic valve is installed simultaneously, temperature sensor is all connected with controller with electromagnetic valve, in the time that cooling fluid cavity temperature is higher, when controller is received the higher temperature data that temperature sensor transmits, control electromagnetic valve and increase valve opening, to accelerate the replacing speed of cooling fluid in cooling sap cavity, so that the temperature in cooling sap cavity is lowered, thereby realize the control to expansion type cavity temperature; In the time that cooling fluid cavity temperature is lower, when controller is received the lower temperature data that temperature sensor transmits, control electromagnetic valve and reduce valve opening, to reduce the replacing speed of cooling fluid in cooling sap cavity, thereby realize the rise of cooling fluid cavity temperature, and then realize the control to expansion type cavity temperature.Therefore, the utility model can be by controlling the temperature of resin melt in cooling fluid control die cavity, micro-foamed polymer material foaming process gas is grown up and obtain Effective Regulation, obtain more satisfactory micro-foamed polymer material, improve foaming product surface quality simultaneously, this device can directly apply to common foaming machine, and transformation difficulty is little, input cost is low, is easy to apply.
