When the movable mold 10 to be detected moves relative to the stationary mold 9 to be detected, the pressure sensor 33 senses the change of the extrusion force of the movable mold 10 to be detected to the PLC 11, the PLC 11 firstly controls the rotating motor 36 to act so that the rotating motor 36 drives the driving gear 37 to rotate, the rotating drum 32 is driven by the meshing action of the driving gear 37 and the driven gear 35 to drive the pressure sensor 33 to rotate 180 degrees to the side, the pressure sensor 33 is prevented from blocking the continuous upward movement of the movable mold 10 to be detected, the PLC 11 simultaneously controls the electric slide rail 413 to drive the second painting brush 416 to move at a uniform speed so that the second painting brush 416 draws a transverse line segment on the display paper 42, the movable mold 10 to be detected continues to move upward until the movable mold 10 to be detected acts on the upper end feedback switch 34, the feedback signal is fed to the PLC 11, the PLC 11 stops the continuous action of the hydraulic push rod 21, and the electric slide rail 413 is controlled to stop, at this time, the transverse line segment drawn by the second brush 416 represents the time when the to-be-detected movable mold 10 moves completely away from the to-be-detected stationary mold 9, and because the larger the clamping force is, the larger the resistance to be overcome in the process of moving the to-be-detected movable mold 10 upwards and away is, the longer the time is required, so that the length of the transverse line segment drawn by the second brush 416 can continuously represent the clamping resistance of the to-be-detected movable mold 10 moving relative to the to-be-detected stationary mold 9 under the currently applied top thrust condition, the longer the transverse line segment is, the larger the moving clamping resistance is, the accurate detection can be performed on the clamping resistance of the mold, the accurate information of the judgment of the clamping resistance of the mold is provided, the detection result is more accurate compared with the existing detection method through direct observation and manual perception, the quality of the clamping resistance detection of the mold is improved, the clamping stagnation of the die can be directly displayed, so that a worker can conveniently and rapidly judge and check the die, and the detection work can be efficiently performed;
When the thermal stability of the mold is required to be detected, high-temperature liquid at 300 ℃ is introduced into the movable mold 10 to be detected and the static mold 9 to be detected, and the high-temperature liquid stays for 30min continuously, and then the detection mode of clamping stagnation force is used for detecting the thermal stability of the mold under the action of high temperature, wherein the thermal stability of the mold refers to whether the mechanical property and the form stability of a material can be maintained under the high-temperature environment of long-time operation of the mold, the problem of clamping stagnation can be caused by poor thermal stability of the mold, when the mold is subjected to the action of high temperature in the injection molding process, the thermal expansion coefficients of different parts of the mold are inconsistent at high temperature, the expansion degree of the movable mold and the static mold after being heated is inconsistent, size mismatch can be generated, and the clamping stagnation is caused, so that the detection result of the thermal stability of the mold can be obtained after the thermal treatment of the mold, the problem of the thermal stability of the mold is influenced, whether the deformation and the deformation degree of the mold can be detected synchronously based on the detection of the clamping stagnation can be avoided by using complex instruments, the detection of whether the mold is greatly reduced in cost, and the operation is convenient;
And the high-temperature liquid is stored in the mould for thermal stability detection, and simultaneously, the performance of a mould cooling system can be synchronously detected, at the moment, water is introduced into a cooling channel of the mould through a water pump 51 by utilizing a water inlet pipe 52 and a water supply pipe 53, the pressure of the water pump 51 is fixed, the flow speed of water flow is fixed, the cross section area of the cooling channel can directly reflect the water flow quantity of the cooling channel in a set time, a PLC (programmable logic controller) 11 controls the water pump 51 to work for 5min at regular time, the introduced water is conveyed into a heat-preserving water storage shell 55 through a water outlet pipe 54, the water pump 51 is stopped for 20s after working, the position of a water quantity indicating needle 73 relative to a water quantity graduated scale 74 is observed after the water storage in the heat-preserving water storage shell 55 is stabilized, the more water introduced into the heat-preserving water storage shell 55 indicates that the blocking degree of the mould cooling channel is smaller, the water in the heat-preserving water storage shell 55 enables the upward moving height of a floating ball 77 to be larger, the greater the distance of the upward movement of the water quantity indicating needle 73, the visual display of the blocking degree can be further performed after the detection of the cooling channel of the mold, the rapid detection operation is facilitated, the cooling heat exchange operation can be completed with the high-temperature liquid in the mold when the water is sent in the cooling channel, the introduced water temperature rises, the heat conducting block 84 feeds the introduced water temperature in the heat preservation water storage shell 55 back to the heat conducting cylinder 82, and then acts on the semiconductor resistor 83, because the higher the using environment temperature of the semiconductor resistor 83 is, the more the semiconductor carrier concentration rises, the more the resistance value of the semiconductor resistor 83 is reduced, the resistance of the semiconductor resistor 83 is directly reflected to be reduced along with the rise of the temperature, the higher the water temperature after heat exchange is serially connected on the power supply circuit of the feedback electromagnetic plate 810, the resistance value of the semiconductor resistor 83 is smaller, the stronger the magnetic force of the feedback electromagnetic plate 810, the larger the distance that the feedback permanent magnetic plate 89 is matched to push the feedback plate 87 to move upwards, so that the larger the distance that the temperature indicator needle 811 moves upwards relative to the temperature graduated scale 812 is, the better cooling heat exchange is carried out on high-temperature liquid in a die by the introduced water, the better the use effect of a cooling system of the die is, the lower the water temperature after heat exchange is, the worse the cooling heat exchange effect of the high-temperature liquid in the die is, whether the cooling channel of the die is blocked or not can be rapidly detected, the blocking degree can be visually displayed, the rapid detection can be synchronously carried out on the cooling heat exchange performance of the die, visual display is carried out, and the detection operation of an maintainer is convenient.
