[0032] The piston rod 14 - 1 of the oil cylinder 14 pushes the slider 9 to slide, and the sliding of the slider 9 causes the guide slider 8 thereon to rise, thereby allowing the temperature sensor probe 10 to pass through the temperature measuring through hole 601 of the plastic product 6 .

[0033] like Figure 3 As shown, the slider 9 includes a slider body 901, one side of the slider body 901 is provided with an inclined surface 902, the inclined surface 902 is provided with a protrusion 903, the protrusion 903 is provided with an end surface 904 for sliding into the guide slider 8 and an end surface 905 for limiting the position of the guide slider 8.

[0034] The second end surface 905 of the first inclined surface 902 is higher than the first end surface 902 , and is used to guide the slider 8 to rise, thereby facilitating the temperature sensor probe 10 to extend into the temperature measuring through hole 601 of the plastic product 6 .

[0043] An inserting groove 909 matching the size of the piston rod of the oil cylinder 14 is formed at the end of the slider body 901 , and the piston rod of the oil cylinder 14 is inserted into the inserting groove 909 .

[0044] In this embodiment, the wires on the temperature sensor probe 10 are connected to the corresponding control system.

[0045] The process of measuring the internal temperature field of the plastic product 6 in the utility model is as follows:

[0046] like Figure 6-7 As shown, before temperature measurement, the temperature sensor probe 10 retreats to the bottom surface of the plastic product 6; after injection and pressure holding are completed, the piston rod 14-1 of the cylinder 14 extends, pushing the slider 9 forward along the groove 501, and the movement of the slider 9 drives the guide slider 8 to move upward along the protrusion 903. The guide slider 8 rises with the temperature sensor fixing block 11 and the temperature sensor probe 10, so that the temperature sensor probe 10 is inserted into the temperature measuring through hole 601 in the plastic product 6, and the software is opened to start collecting temperature field data.
