Detailed description of the invention
In order to make content of the present invention clearly with understandable, below in conjunction with specific embodiments and the drawings, content of the present invention is described in detail.
Fig. 1 schematically shows the structured flowchart of the automobile absorber shell injection mold according to the embodiment of the present invention; Fig. 2 is the structural representation of die assembly in Fig. 1.
As depicted in figs. 1 and 2, the structure of automobile absorber shell injection mold of the present invention comprises: drawing mechanism 1, heating furnace 2, die assembly 3, feeding back device 4 and controller 5.
One end of heating furnace 2 is communicated with drawing mechanism 1 by feed pipe 21, and the other end of heating furnace 2 is communicated with die assembly 3 by discharge nozzle 22.In the present embodiment, heating furnace 2 receives the material in drawing mechanism 1, and will be sent to die assembly 3 after heating material, is injected the shell of automobile absorber by die assembly 3, heating furnace 2 is spinning thermotank, and this thermotank is formed as the little shape broad in the middle in two.
In the present embodiment, discharge nozzle 22 is provided with temperature detector 6 and outlet valve 7, this temperature detector 6 and outlet valve 7 are all electrically connected with controller 5, temperature detector 6 is for detecting the temperature of material in discharge nozzle 22 in real time, and detected temperatures is sent to controller 5, material for die assembly 3 feed, or is inputted feeding back device 4 by outlet valve 7.
The die cavity of die assembly 3 is provided with the batch mixing pan 31 be communicated with discharge nozzle 22, and batch mixing pan 31 is provided with several and gets rid of material hole 32, and batch mixing pan 31 is provided with driven gear 33, driven gear 33 is connected with drive motors 35 by driving gear 34.Drive motors 35 drives driving gear 34, and drives batch mixing pan 31 to rotate by driven gear 33, and the material exported in discharge nozzle 22 enters batch mixing pan 31, gets rid of material hole 32 throw away by several.
One end of feeding back device 4 is communicated with feed pipe 21 by the first feed back pipe 41, and the other end of feeding back device 4 is communicated with discharge nozzle 22 by the second feed back pipe 42.This feeding back device 4 fails to reach the material of requirement temperature value for receiving temperature, and by this feed back to heating furnace 2, with while raising injection moulding quality, does not waste material.
The detected temperatures that controller 5 sends for receiving temperature detector 6, returned signal is transmitted lower than during preset temperature to outlet valve 7 in detected temperatures, the material that heating furnace 2 is exported enters feeding back device 4 and is back to heating furnace 2, be conveyed into mould signal greater than or equal to during preset temperature to outlet valve 7 in detected temperatures, the material that heating furnace 2 is exported enters die assembly 3.
When detected temperatures is lower than preset temperature, then show that the temperature of material in discharge nozzle 22 fails to meet the requirements of temperature value, now should not by this material input die assembly 3, but also should not waste this material, this enforcement is by this material input feeding back device 4, and make it be back to heating furnace 2, so both can prevent the temperature of material in injection mold from failing to meet the requirements of temperature value, effectively reclaim again the material that temperature fails to reach requirement temperature value.
In the present embodiment, be provided with material detector 8 in feeding back device 4, material detector 8 is electrically connected with controller 5.This material detector 8 is for detecting the inventory in feeding back device 4 in real time, and detection inventory is sent to controller 5, when the material in feeding back device 4 is inputted heating furnace 2 in detection inventory higher than during default inventory by controller 5, such as, detect there is material in feeding back device 4 time, controller 5 material controlled in feeding back device 4 transfers to feed pipe 21, to be back to heating furnace 2.
The present embodiment also comprises preset temperature and arranges device 9, and this preset temperature arranges device 9 for arranging preset temperature, preset temperature depending on damper shell material and set.
Thus, automobile absorber shell injection mold of the present invention, temperature detector is adopted to detect the temperature of material in discharge nozzle in real time, and detected temperatures is sent to controller, controller transmits returned signal lower than during preset temperature to outlet valve in detected temperatures, the material that heating furnace is exported enters feeding back device, and be back to heating furnace, fail to meet the requirements of temperature value to prevent the temperature of material in injection mold, and effectively reclaimed the material that temperature fails to reach requirement temperature value, only be conveyed into mould signal greater than or equal to during preset temperature to outlet valve in detected temperatures, just the material that heating furnace exports is entered die assembly.
Therefore, automobile absorber shell injection mold of the present invention, injection moulding quality is high, and effectively can reclaim the material that temperature fails to reach requirement temperature value, has saved material.
