[0002] When extruding the profile, a mold is needed to assist in the molding. After the product is formed, it will exist inside the mold. In order to take the product out, a demolding tool is needed to perform demolding. Under normal operation, the operator needs to place the mold and the product as a whole in the demolding tool, and manually calibrate the mold so that it can be aligned with the output port of the demolding tool, and then start the demolding tool to complete the demolding operation. This method has a high degree of manual participation, and the manual calibration and alignment is inefficient and accompanied by safety risks. At the same time, due to the weight of the mold and the product, the operation process is more physically demanding.

[0010] Preferably, the moving assembly includes a dual-axis motor and a moving wheel, and the moving wheel is rotatably connected to the second mounting frame.

[0011] By adopting the above technical solution, the beneficial effects of the utility model are:

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0020] Example 1

[0021] Demolding tools for profile extrusion dies, such as Figure 1 and Figure 2 As shown, it includes a mounting platform 1, a first mounting frame 2 is placed at the rear side of the mounting platform 1, the left and right parts of the mounting platform 1 are connected to limiting columns 3, and a cutting piece 4 for smooth cutting of corners is slidably arranged between the limiting columns 3, a first hydraulic cylinder 5 is installed on the top of the mounting platform 1 by bolts, and the telescopic end of the first hydraulic cylinder 5 is connected to the top of the cutting piece 4, and a discharging guide seat with an inclined structure is connected to the front side of the lower part of the mounting platform 1, a second hydraulic cylinder 6 is connected to the first mounting frame 2, and the telescopic end of the second hydraulic cylinder 6 is a multi-stage structure, an oil pump 9 is installed on the top of the first mounting frame 2, and the oil pump 9 is connected to the first hydraulic cylinder 5 and the second hydraulic cylinder 6 through a pipeline, and a calibration mechanism 7 for automatic calibration and positioning of the mold is arranged on the telescopic end of the second hydraulic cylinder 6.

[0022] like Figure 1 and Figure 3 As shown, the calibration mechanism 7 includes a propulsion plate 71, the propulsion plate 71 is connected to the telescopic end of the second hydraulic cylinder 6, the propulsion plate 71 is slidably connected to the mounting table 1, a calibration ring 72 for pushing and calibrating the mold is slidably provided on the front side of the propulsion plate 71, an external buffer plate 73 is slidably provided on the calibration ring 72, and four buffer springs 74 are connected between the external buffer plate 73 and the calibration ring 72.

[0023] It should be noted that after the profile is stamped and finalized, the device can be used to demould the product. First, the mold is placed at the rear of the mounting table 1 by relying on the equipment, and then the second hydraulic cylinder 6 is started. The telescopic end of the second hydraulic cylinder 6 first extends in the first stage, so that the push plate 71 drives the calibration ring 72 to move forward. After the calibration ring 72 contacts the mold, it will push the mold forward, so that the mold fits with the placement groove at the rear of the mounting table 1. In this process, the mold will fit with the placement groove at the rear of the mounting table 1 until it is fully aligned. The external buffer plate 73 will be squeezed and the buffer spring 74 will be compressed, so as to avoid excessive impact force when the telescopic end of the second hydraulic cylinder 6 extends in the first stage, causing damage to the mold or the calibration ring 72. After the alignment is completed, the telescopic end of the first hydraulic cylinder 5 is controlled to extend downward, so that the cutting piece 4 cuts the product in the mold evenly. After the cutting is completed, the cutting piece 4 is controlled to move upward and reset, and then the telescopic end of the second hydraulic cylinder 6 is controlled to extend in the second stage, so that the formed product is pushed out of the mold. After the product is pushed out, it will be discharged along the discharge guide seat, and the demoulding process is completed.

A crane 83 is connected to the lower part of the moving component 82, and the crane 83 has a hook 84.

[0026] It should be noted that when transporting and feeding the mold, the crane 83 can be controlled to drive the hook 84 to connect with the mold, and then the moving component 82 can be operated to drive the crane 83 to move, so that the mold can be lifted and transported, further improving the efficiency of demolding. The integrated setting can also reduce the participation and investment of other equipment, making the overall integration of the device higher.
