[0029] Specifically, the second movable assembly 6 includes a fixed seat 601 arranged on one side of the bottom mold 1, a second slider 602 is fixedly connected to one side of the second insert 302, a top of the fixed seat 601 is fixedly connected to a cylinder 603, and the second slider 602 is fixedly connected to the output end of the cylinder 603.

[0030] It should be noted that the first slider 501 is arranged at the top of the second slider 602, and the push groove 502 opened on the top of the first slider 501 is adapted to the guide column 503. When the top plate 4 is used to drive the top mold 2 to move for mold opening, the top plate 4 drives the inclined guide column 503 to move upward, and the first slider 501 is moved to the side away from the mold through the guide column 503, so that the first slider 501 is moved and the first insert 301 is driven to move to the side away from the mold, thereby completing the separation between the first insert 301 and the product; at the bottom of the bottom mold 1 A bracket for supporting the bottom mold 1 is provided, and a fixed seat 601 is fixed on the top of the bracket, so that the position of the fixed seat 601 is fixed by the bracket, and a second slider 602 is provided at the top of the fixed seat 601, one side of which is connected to the second insert 302, and the other side is fixedly connected to the output end of the cylinder 603. When the second insert 302 needs to be separated from the product, the second slider 602 is directly driven by the cylinder 603 to move to the side away from the mold, and the second slider 602 drives the second insert 302 to be separated from the product.

[0031] Specifically, the driving member includes a third slider 7 fixedly connected to one side of the third insert 303, a limiting screw 10 is fixedly connected to one side of the second slider 602, a stroke control part 9 for limiting the movement of the third slider 7 is provided on one side of the third slider 7, and a connecting part 8 is provided at the connection between the third slider 7 and the limiting screw 10.

[0032] Specifically, the connecting part 8 includes a driving groove 802 opened on one side of the third slider 7, a connecting hole 801 is opened on the inner wall of one side of the driving groove 802, and a limit screw 10 is inserted and connected inside the connecting hole 801 and the driving groove 802.

[0033] It should be noted that the opened slide groove 904 is adapted to the set movable block 901, and the bottom of the movable block 901 is inserted and connected to the inside of the slide groove 904. The movable block 901 is restricted by the slide groove 904, and the moving direction of the movable block 901 is the direction in which the slide groove 904 is opened, and the set blocking block 902 is fixedly connected to the top of the movable block 901. The moving direction of the blocking block 902 is restricted by the movable block 901 that limits the moving direction. When the blocking block 902 is fitted with one side of the third sliding block 7, the blocking block 902 makes the third sliding block 7 The three sliders 7 cannot move to the side away from the mold, and the position of the third slider 7 is limited by the blocking block 902; the horizontal longitudinal section of the top of the movable block 901 is trapezoidal, and a groove adapted to the top of the movable block 902 is provided at the bottom of the pressing block 903. When the position of the third slider 7 is fixed by the blocking block 902, the top of the movable block 901 is located in the groove provided at the bottom of the pressing block 903. When it is necessary to separate the blocking block 902 from the third slider 7, the pressing block 903 is moved by the second slider 602, so that the movable block 901 moves out of the pressing block 903. The pressing block 903 is outside the groove at the bottom, and the movable block 901 is pressed into the inside of the sliding groove 904 by the pressing block 903. The movable block 901 in the moving position drives the blocking block 902 to move, so that the blocking block 902 is separated from the third sliding block 7, and the blocking of the third sliding block 7 is lost. The spring 905 is used to push the movable block 901 to the side away from the sliding groove 904, so that when the top of the movable block 901 loses the squeeze, the movable block 901 is driven to reset by the spring 905; one end of the set limit screw 10 is fixedly connected to one side of the second sliding block 602 The driving groove 802 is matched with the screw head of the limiting screw 10, the connecting hole 801 is matched with the screw rod of the limiting screw 10, and the horizontal longitudinal area of ​​the driving groove 802 is larger than the horizontal longitudinal cross-sectional area of ​​the connecting hole 801, so that the limiting screw 10 can move out of the driving groove 802 through the connecting hole 801, so that when the position of the third slider 7 needs to be moved, the limiting screw 10 is driven to move by the second slider 602, and when the screw head of the limiting screw 10 moves to fit with the inner wall of one side of the driving groove 802, the third slider 7 is driven to move by the pulling of the limiting screw 10.

[0034] When demoulding:

[0035] In the first step, the top plate 4 drives the top mold 2 to move upward, and drives the guide column 503 through the top plate 4 to pull open the first slider 501, slide 20mm, and drive the first insert 301 to move through the first slider 501, so that the product is separated from the first insert 301.

[0036] In the second step, the oil cylinder 603 drives the second slider 602 to move, causing it to slide 50 mm, thereby allowing the product to separate from the second insert 302 .

[0037] In the third step, before the oil cylinder 603 pulls the second slider 602 to move 15 mm, the second slider 602 drives the pressing block 903 to press the movable block 901 into the inside of the slide groove 904, but one side of the blocking block 902 is still in contact with one side of the third slider 7. The third slider 7 is blocked by the blocking block 902 and is immobile. When the second slider 602 moves more than 15 mm, it drives the movable block 901 to drive the blocking block 902 to separate from the third slider 7, releasing the third slider 7, and then the limiting screw 10 set on one side of the second slider 602 pulls the third slider 7 to move another 35 mm, thereby separating the product from the third insert 303, thereby completing the separation of the product from multiple inserts.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
