In the above mold, after the molten casting liquid enters the casting channel, the temperature sensor 10 and the pressure sensor 10 in the casting channel respectively detect the temperature and the pressure of the casting liquid, so as to adjust the temperature and the injection speed of the casting liquid according to the detected values. The casting liquid then flows along the casting channel into the first cavity 122. At the end of the first cavity 122 away from the pouring channel, i.e. the pouring end, the temperature sensor 10 and the pressure sensor 10 at the end detect the pouring liquid again. The pouring information of the pouring liquid is obtained through the two detection positions, so that the function of detecting the temperature and the pressure in the mold is realized.

Referring to fig. 1, an end of the pouring channel away from the first cavity 122 is a first placing point 110 for placing the temperature sensor 10 and the pressure sensor 10, and an end of the first cavity 122 away from the pouring channel is a second placing point 120 for placing the temperature sensor 10 and the pressure sensor 10.

In this embodiment, the body 100 further includes a housing, and the temperature sensor 10 and the pressure sensor 10 located at the same position of the body 100 are both accommodated in the housing. It can be understood that the temperature sensor 10 and the pressure sensor 10 are arranged in the same shell, so that part of installation parts can be omitted, the internal space of the die is saved, and the structural compactness of the die is improved.

In the present embodiment, the number of the pouring channels is two or more. It is to be added that the number of pouring channels can be adapted to the mould cavity. A pressure sensor 10 and a temperature sensor 10 are arranged in any pouring channel.

In a specific embodiment, the body 100 further includes a second cavity 124 identical to the first cavity 122, a pressure sensor 10 and a temperature sensor 10 are disposed at any position of the second cavity 124, and the pressure sensor 10 and the temperature sensor 10 are disposed at the same position of the first cavity 122.

It is important to note that when the mold has a plurality of second cavities 124, a plurality of pressure sensors 10 and temperature sensors 10 may be disposed in the first cavity 122, so as to monitor the temperature and pressure in the first cavity 122 comprehensively. Further, the temperature sensor 10 and the pressure sensor 10 are disposed at the same position by the first cavity 122 and the second cavity 124. When the temperature values are consistent with the pressure values, it can be determined that the temperatures and pressures of the second cavity 124 and the first cavity 122 at the maximum positions are substantially consistent. By adopting the layout mode of the sensor, the use of the number of the sensors can be reduced, the production cost is reduced, and the competitiveness of products is improved.

In this embodiment, the body 100 is further provided with a temperature sensor 10 for detecting the temperature of the body 100. It should be noted that the temperature sensor 10 is not disposed in the pouring channel and the first cavity 122, but is disposed at other positions of the mold. It is mainly used for detecting the temperature of the body 100 to determine whether the mold reaches the temperature of pouring.

In this embodiment, the body 100 includes a first mold and a second mold, the first mold and the second mold are fastened to form a first cavity 122, and the body 100 is provided with a position sensor for detecting a position change of the first mold and the second mold on a fastening surface of the first mold and the second mold. It will be appreciated that during casting, the flow of the casting liquid exerts a certain pressure on the body 100, which tends to cause a change in the relative position of the first and second dies, thereby affecting the accuracy and quality of the casting. By adopting the design of the position sensor, the real-time monitoring of the buckling surfaces of the first die and the second die can be improved, so that the corresponding adjustment can be conveniently carried out on different conditions.
