Description

Technical Field

[0002] At present, effective control of the temperature balance of the die-casting mold is a key parameter condition for improving the quality of die-casting. If the temperature of the die-casting mold is too high, the mold will crack prematurely, the slider and ejector and other active mechanisms will be seriously worn, the casting quality will be unstable, and defects such as deformation, pores, and bubbles will appear; if the temperature of the die-casting mold is too low, the die-casting parts will appear, the filling will not be full, the shrinkage will be serious, the cold shut will be poor in surface finish.

[0003] The control switch of the existing intelligent control equipment for mold thermal balance can only be manually controlled to be turned on and off. The mold is in a cooling state for a long time when water is passed through it, and the mold temperature balance cannot be effectively achieved. In addition, in order to save cost investment, traditional workshops generally pass the tap water from the die-casting workshop into the mold waterway, and return it to the workshop water tank without any filtration system for recycling, which seriously affects the quality of the raw water. Since there are impurities and pollutants in the cooling raw water passed through the mold waterway, the mold water passing can easily cause scaling and blockage in the mold waterway, resulting in poor mold cooling effect, and uneven water passing through the mold waterway, affecting the mold thermal balance effect, and easily causing the mold temperature to be too high, which is not conducive to extending the service life of the mold, increasing the cost of mold maintenance and replacement, reducing the product qualification rate, and seriously affecting the quality of die-casting products. Moreover, the blockage of the mold waterway is not easy to find, and the waterway will only be checked when the defective rate is very high, resulting in an increase in defective products and a waste of manpower, material and financial resources.

[0078] See also Figure 7 The specific working process of the mold thermal balance intelligent control device 10 of this embodiment is as follows:

[0079] (1) First, the relevant parameters can be manually set on the touch screen 220, and the branch pipe 143 of the diversion component 140 is connected to the mold waterway port. When the equipment is started, the pressure pump 110 draws raw water from the water tank 210, and the raw water flows into the filter device 150 for filtering and purification;

[0080] (2) The filtered raw water flows into the mold water channel through the diversion component under the program control of the PLC programmable controller, and the mold water channel is cooled by water to ensure the thermal balance of the mold. The first temperature sensor detects the mold temperature and sends the temperature signal to the PLC programmable controller for processing. The PLC programmable controller controls the water flow time according to the detected mold temperature;

[0081] (3) When the water supply time is up, the water supply is stopped, the solenoid valve 145 controls the water pipe 170 to close, the air pipe 180 to open, and the compressed air machine 130 controls the compressed air to flow into the mold waterway through the air pipe 180 and the diversion component 140, so as to clean the mold waterway and remove the residual raw water, impurities and pollutants in the waterway. The air compressor 130 can heat or cool the compressed air through the condenser 136 and the heater 1312, thereby further ensuring the thermal balance effect of the mold;

[0082] (4) When the ventilation time is up, the blowing stops, and the solenoid valve 145 controls the air pipeline 180 to close, thereby completing a working cycle and waiting for the next cycle to work.

[0083] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
