Brief description of the drawings
Fig. 1 is a kind of schematic flow sheet of the mold temperature control method heated automatically proposed by the present invention.
Embodiment
Reference picture 1, a kind of mold temperature control method heated automatically proposed by the present invention, including：
Step S1, injection mold lower cover is preset as n detection zone A1、A2…An, specifically include：By injection mold Lower cover is preset as n rectangle detection zone, and each rectangle detection zone size is identical.
In concrete scheme, injection mold lower cover is subjected to detection zone division, inspection according to the true form of lower cover The quantity of region division and the shape of division are surveyed depending on actual conditions, for simple rectangle lower cover, can be incited somebody to action Injection mold lower cover is preset as several rectangle detection zones, and each rectangle detection zone size is identical.
Step S2, default and A1、A2…AnOne-to-one heater B1、B2…Bn, wherein, B1、B2…BnMiddle difference is pre- Provided with target temperature R1、R2…Rn, specifically include：Target temperature R1、R2…RnSize and B1、B2…BnBetween mould gate Distance it is directly proportional.
It is default to be heated correspondingly with each detection zone according to the situation of detection zone division in concrete scheme Device, is preset with each heater and target temperature value, due to can gradually be dropped with the diffusion of solution, solution temperature It is low, so the size of the target temperature value is directly proportional to the distance between heater and mould gate, ensure solution edge Temperature is in the range of requiring.
Step S3, solution image in injection mold is obtained, m in the n detection zone that will be covered by solution image examines Region is surveyed as object detection area to gather, wherein, m≤n is described to obtain solution image in injection mold, specifically includes：Pass through Thermal infrared imager obtains solution image in injection mold.
In concrete scheme, solution image in injection mold is obtained by thermal infrared imager, it is true according to the solution image M detection zone in the fixed n detection zone covered by solution image, using m detection zone as object detection area collection Close.
Step S4, obtain the solution temperature T of any of object detection area set object detection areai, wherein, i≤ M, specifically include：The solution temperature of any of object detection area set object detection area is obtained by infrared video camera Ti, the TiTake the minimum value of solution temperature in the object detection area.
In concrete scheme, any of object detection area set object detection area is obtained by thermal infrared imager Solution temperature, wherein, the solution temperature of object detection area is the minimum in the solution each point temperature in the object detection area Temperature.
Step S5, by TiWith corresponding RiIt is compared, heater B is started according to comparative resulti, specifically include：
By TiWith corresponding RiIt is compared, works as Ti＜ RiWhen, start heater BiSo that Ti≥Ri。
In concrete scheme, by the solution temperature of the object detection area obtained by thermal infrared imager and corresponding detection The target temperature in region is compared, when the solution temperature of object detection area is less than the target temperature of corresponding detection zone When, illustrate that the solution temperature of object detection area is not up in claimed range, now start heating dress corresponding with detection zone Put, the solution temperature of object detection area is reached the target temperature of corresponding detection zone.
