In the accompanying drawing: 1, part; 2, formpiston; 3, former; 4, eddy current cold air rifle; 41, inlet channel; 42, cold air path; 43, hot gas path; 5, radiating tube; 51, an end; 52, the other end.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
A kind of injection mold, it comprises formpiston 2, former 3, cooling device.
As shown in Figure 3, cooling device comprises eddy current cold air rifle 4 and the radiating tube 5 that is arranged in the formpiston 2.
As shown in Figure 4, cooling device comprises eddy current cold air rifle 4 and the radiating tube 5 that is arranged in the former 3.
Eddy current cold air rifle 4 has inlet channel 41, is used for being divided into from the gas that inlet channel 41 enters the vortex device of cold air and hot gas, and communicate with vortex device and be respectively applied to collect cold air path 42 and the hot gas path 43 of cold air and hot gas.Compressed air after 4 utilizations of eddy current cold air rifle are filtered and the technology of vortex tube (namely utilize compressed air, by the conversion of vortex tube, cold air path 42 produces cold air, and hot gas path 43 produces hot gas).So that production process Air temperature reaches subzero, such cooling effectiveness is widely used in industrial occasions.There are not movable parts, not fragile, easy care.This conversion by the vortex tube technology has realized utilizing compressed air to convert cold airflow to, makes that temperature can be reduced to-30 °F in the production process.
The cold air path 42 of eddy current cold air rifle 4 is connected with an end 51 of radiating tube 5, and the other end 52 of radiating tube 5 is connected with the external world, and the hot gas path 43 of eddy current cold air rifle 4 is connected with the external world.
Operation principle of the present utility model is to obtain cold air by eddy current cold air rifle 4, and with cold air from an end 51 input radiating tubes 5 of radiating tube 5, carry out heat exchange by the radiating tube 5 that is arranged in the mould again, reduce the heat in the mould, in this process, the cold air in the radiating tube 5 becomes hot gas and discharges from the other end 52 of radiating tube 5.
The utility model is learning that through after a large amount of extensive experimentation only after the good cooling of process, glue shrinkage factor difference thick and that glue is thin is little, and the quality at the position that glue is thick can be guaranteed, and has solved the little problem of the thick scope of original glue.Thereby mould only could be processed the thick position of glue in the situation of the cooling device in comprising the utility model.
The utility model adopts above structure to have the following advantages:
