As shown in fig. 1-3, a mold temperature control device includes a mold 1, a remote temperature measuring device 2, and a mold temperature controller 3.
Wherein, the mould 1 comprises a male mould 11 and a female mould 12 which are arranged on an injection moulding machine 4; specifically, the male mold 11 is arranged on a movable mold plate 41 of the injection molding machine 4; the master mold 12 is disposed on a stationary platen 42 of the injection molding machine 4, which is also in communication with an injection molding inlet 43. The male die 11 and the female die 12 are driven by the movable die plate 41 to open and close.
The male die 11 and the female die 12 are both provided with temperature adjusting pipelines 13; the mold temperature controller 3 is provided with two pairs of temperature control circulating liquid pipes 31 which are respectively communicated with the inlets and outlets of the temperature control pipelines 13 of the male mold 11 and the female mold 12. Preferably, the temperature-adjusting circulating liquid adopted by the mold temperature controller 3 is water or temperature-adjusting oil. During injection molding, when the mold temperature is higher than or lower than a predetermined temperature, the mold temperature controller 3 correspondingly cools or heats the temperature-adjusting circulating liquid, and then the temperature-adjusting circulating liquid enters the temperature-adjusting pipeline 13 to cool or heat the mold 1.
The remote temperature measuring device 2 is an infrared remote temperature sensing sensor and is electrically connected with the mold temperature controller 3 in a conventional mode (such as a signal wire connection mode); the remote temperature measuring device 2 is aligned to the mould 1, and the temperature measuring point is positioned on the mould 1; the remote temperature measuring device 2 measures the temperature of the die 1 and transmits information to the die temperature controller 3, so that the die temperature controller 3 cools or heats the temperature-adjusting circulating liquid; preferably, at least two temperature measuring points of the remote temperature measuring device 2 are arranged and are respectively and uniformly distributed on the male die 11 and the female die 12, so that errors are eliminated, and the accuracy of a temperature measuring result is improved.
Compared with the conventional mode, the remote temperature measurement mode can flexibly increase temperature measurement points according to needs, so that the detection result is more accurate, and the detection flexibility is higher; meanwhile, the method has better applicability and universality and has less dependence on the die 1.
In addition, a plurality of partition plates 131 for radially partitioning the temperature adjusting pipeline 13 are arranged in the temperature adjusting pipeline, and a plurality of through holes 132 are formed in the partition plates 131; the through holes 132 are different in size, and the inner walls of the through holes 132 are provided with threads.
The temperature-adjusting circulating liquid flows in the temperature-adjusting pipeline 13 and passes through the through hole 132 when meeting the partition plate 131; when passing through the through-hole 132, its instantaneous flow rate becomes large; according to the Bernoulli principle, after passing through the partition plate 131, the pressure of the part of the temperature-regulating circulating liquid is reduced, so that the problem of unbalanced pressure of the temperature-regulating circulating liquid around the part of the temperature-regulating circulating liquid is caused, and the convection between the temperature-regulating circulating liquid is increased, so that the heat in the temperature-regulating circulating liquid can be better transferred, and the temperature-regulating effect and efficiency can be improved; meanwhile, the sizes of the through holes 132 are different, and the design of the threads can increase random movement of the temperature-adjusting circulating liquid, so that collision of molecules in the temperature-adjusting circulating liquid is increased, heat transfer in the temperature-adjusting circulating liquid is promoted, and the temperature-adjusting effect and efficiency are further improved.
In light of the foregoing, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
