[0024] The following is combined with Figure 1-5 This application is described in further detail.

[0025] Reference Figure 1-Figure 5 A door and window inner panel mold includes an upper mold 1 and a lower mold 2. A placement groove 3 is vertically opened on the lower mold 2. A lifting hole 4 is vertically opened on the bottom of the placement groove 3. A lifting rod is inserted on the lifting hole 4. The lifting rod includes a moving part 5 and an adjusting part 6. The adjusting part 6 is threadedly connected to the moving part 5. The upper end of the adjusting part 6 abuts against the upper mold 1, and the moving part 5 is located in the lifting hole 4.

[0026] Reference Figure 1-Figure 5 , a resistance ring 7 is fixedly arranged on the moving part 5, a resistance spring 8 is sleeved on the moving part 5, one end of the resistance spring 8 is in resistance to the bottom of the placement groove 3, and the other end is in resistance to the placement resistance ring 7; a mounting groove 16 is provided on the lower mold 2, a buffer groove 9 is vertically provided on the groove wall of the mounting groove 16, a telescopic spring 10 is arranged in the buffer groove 9, one end of the telescopic spring 10 is fixedly connected to a lifting plate 11, and a touch switch 12 is fixedly arranged on the lifting plate 11; an indicator light 13 is fixedly arranged on the lower mold 2, and the touch switch 12 is electrically connected to the power line of the indicator light 13, and is used to control the light emission of the indicator light 13; the touch switch 12 is located below the moving part 5;

[0027] Reference Figure 1-Figure 5When the inner panels of doors and windows are being formed, the upper mold 1 moves down and contacts the lowering of the lifting rod. When the upper mold 1 moves down to the lowest height, if the lifting rod contacts the touch switch 12, the touch switch 12 is in the on state, and the indicator light 13 is powered on and illuminated; if the lifting rod does not contact the touch switch 12, the touch switch 12 is in the off state, and the indicator light 13 does not illuminate, allowing the staff to promptly judge whether the upper mold 1 is pressed down to the required height.

[0028] Reference Figure 1-Figure 5 There are multiple lifting rods on the four sides of the lower mold 2, and multiple lifting rods are tested simultaneously to further improve accuracy; when the mold is in place, the resistance spring 8 resists the tightening ring and moves upward until the moving part 5 is out of contact with the touch switch 12; when the upper mold 1 is over-pressed, the lifting rod resists the touch switch 12 and moves downward, and the lifting plate 11 moves downward to buffer the touch switch 12. According to the different thicknesses of the door and window inner panels, the height of the lifting rod is adjusted by rotating the adjustment part 6 to achieve the effect of convenient application of door and window inner panels of different thicknesses.

[0029] Reference Figure 1-Figure 5 A pressure sensor 14 is fixedly arranged at the bottom of the buffer groove 9, and the lower end of the telescopic spring 10 abuts against the pressure sensor 14. A controller 17 is fixedly arranged on the lower mold 2, and the controller 17 is electrically connected to the pressure sensor 14. An alarm 15 is fixedly arranged on the lower mold 2. The alarm 15 in the present application is a buzzer, and a switch is electrically connected to the alarm 15. The switch of the alarm 15 is electrically connected to the controller 17. When the pressure value sensed by the pressure sensor 14 exceeds the set value, the pressure sensor 14 transmits a signal to the controller 17, so that the controller 17 controls the switch of the alarm 15 to turn on, so that the alarm 15 sounds an alarm, thereby promptly reminding the staff that the upper mold 1 is over-pressed, so that the staff can stop the machine for maintenance in time.

[0030] Reference Figure 1-Figure 5 In this application, the indicator light 13, the alarm 15, the controller, and the pressure sensor 14 can be powered by mains electricity or a battery; Figure 5 As shown, the structure of the inner panel of the door and window is uneven during molding. In order to reduce the unevenness and improve the molding effect, it is very important whether the upper mold 1 is fully pressed.

[0031] The implementation principle of this embodiment is: when the inner panel of the door and window is being formed, the upper mold moves down to contact the lowering of the lifting rod. When the upper mold moves down to the lowest height, if the lifting rod contacts the touch switch 12, the touch switch 12 is in a pass state, allowing the indicator light 13 to be powered on and illuminated; if the lifting rod does not contact the touch switch 12, the touch switch 12 is in an open state, and the indicator light 13 does not illuminate, allowing the staff to promptly judge whether the upper mold is pressed down to the required height.
