Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figure 1-7 A rotatable demoulding machine for inspection includes a support mechanism 1, a mold mechanism 2 is symmetrically installed inside the support mechanism 1, a demoulding mechanism 3 and a visual inspection device 5 are also installed inside the support mechanism 1, and the visual inspection device 5 faces the demoulding mechanism 3;

[0034] The demoulding mechanism 3 is located directly above the intersection of the two mold mechanisms 2, and a rotating mechanism 4 is installed on the side of the demoulding mechanism 3;

[0035] The mold mechanism 2 includes a driving device, the end of which is fixedly connected to a mold connecting plate 203, an injection mold 204 is installed on the mold connecting plate 203, and the injection molds 204 on both sides are pulled closed and opened by the driving device;

[0036] The demoulding mechanism 3 includes a vertical guide rail 302 and a power distribution and gas supply device 306. The vertical guide rail 302 is located at the inner top of the support mechanism 1. A vertical slider 303 is installed on the side of the vertical guide rail 302. A rotatable extension component 304 is installed at the bottom of the vertical slider 303. A demoulding suction cup 305 is fixedly connected to the bottom of the extension component 304. The vertical guide rail 302 and the vertical slider 303 are electrically connected to the power distribution and gas supply device 306 respectively, and the extension component 304 is connected to the power distribution and gas supply device 306 through a conduit.

[0037] The rotating mechanism 4 includes a servo motor 401 , which is mounted on the side of the vertical guide rail 302 . A transmission disc 402 is mounted on the output shaft of the servo motor 401 , and the outer surface of the transmission disc 402 is in contact with the outer surface of the extension component 304 .

[0038] Through the above technical solution, the vertical guide rail 302 is arranged to drive the vertical slider 303 to move vertically up and down, so that after the injection molding is completed, the demoulding suction cup 305 is driven to descend to adsorb the product, and the demoulding is achieved by the rise of the demoulding suction cup 305. During the demoulding process, the transmission plate 402 drives the extension component 304 to rotate, so that the demoulding is smoother, and only one visual inspection device 5 is needed to inspect the product in an all-round manner, thereby achieving the effect of reducing the number of visual inspection devices 5 arranged;

[0039] The specific steps are: installing the adapted injection mold 204 on the mold connecting plate 203, and then driving the injection mold 204 to close for injection molding through a driving device;

[0040] After the injection molding is completed, the driving device drives the injection mold 204 to unfold, so that the product inside the injection mold 204 is exposed;

[0041] Then the vertical guide rail 302 drives the demoulding suction cup 305 to descend, and the vacuum pump in the power distribution and air supply device 306 starts to work, so that the demoulding suction cup 305 generates suction force on the product;

[0042] At the same time, the servo motor 401 drives the transmission plate 402 to rotate, so that the extension component 304 rotates accordingly, so that the product is completely separated from the injection mold 204, and the visual inspection device 5 inspects the appearance of the product when the product rotates.

[0043] Specifically, the driving device includes a hydraulic rod 201 and a hydraulic controller 202. The hydraulic rod 201 is installed on the inner wall of the support mechanism 1, and the hydraulic controller 202 is installed on the outer surface of the support mechanism 1. The hydraulic controller 202 and the hydraulic rod 201 are connected to each other.

[0044] The mold connection plate 203 is installed at the end of the hydraulic rod 201.

[0045] Through the above technical solution, the hydraulic rod 201 and the hydraulic controller 202 are used to drive the mold connecting plate 203, so that the moving distance and moving speed of the mold connecting plate 203 can be accurately controlled by controlling the flow rate of the hydraulic oil;

[0046] Furthermore, the pressure provided by the hydraulic rod 201 is stronger than that provided by the electric device, thereby making the injection molds 204 fit more closely together and reducing the generation and visibility of the parting line of the product.

[0047] Specifically, the power distribution and gas supply equipment 306 includes a distribution box and a vacuum pump. A PLC module is installed inside the distribution box. The PLC module is electrically connected to the vacuum pump, the vertical guide rail 302 and the vertical slider 303 respectively. The vacuum pump is interconnected with the extension component 304.

[0048] Through the above technical solution, the distribution box is used to install and protect the power supply module and the PLC module, so as to control the vacuum pump, the vertical guide rail 302 and the vertical slider 303, so as to achieve precise displacement and demolding of the product through PLC.

[0049] Specifically, the demoulding mechanism 3 further includes a horizontal guide rail 301, which is fixedly connected to the inner top of the support mechanism 1, and one end or both ends of the horizontal guide rail 301 extend out of the interior of the support mechanism 1;

[0050] The vertical guide rail 302 is installed on the side of the horizontal guide rail 301 and is driven to move forward and backward.

[0051] Through the above technical scheme, the purpose of setting the horizontal guide rail 301 is to enable the vertical guide rail 302 to be pulled by the horizontal guide rail 301 to move in the horizontal direction. After the visual inspection device 5 completes the appearance inspection of the product, the horizontal guide rail 301 drives the vertical guide rail 302 to move forward or backward, and after moving to the specified position, the power distribution and gas supply equipment 306 stops vacuuming the inside of the demolding suction cup 305, so that the product falls from the bottom of the demolding suction cup 305 and is collected.

[0052] Specifically, electric push rods are installed inside the horizontal guide rail 301 and the vertical guide rail 302. The electric push rod in the horizontal guide rail 301 drives the vertical guide rail 302 to move horizontally, and the electric push rod in the vertical guide rail 302 drives the vertical slider 303 to rise and fall vertically.

[0053] Through the above technical solution, the electric push rod is used as the driving force, which takes up less space than the hydraulic device and is more convenient to control;

[0054] Because the space inside the horizontal guide rail 301 and the vertical guide rail 302 is limited, and the space for external piping is also limited, if the horizontal guide rail 301 and the vertical guide rail 302 are both driven hydraulically, at least four pipes are required to transport the hydraulic oil, and the cross-sectional diameter of the pipe is larger than the cross-sectional diameter of the wire. Therefore, an electric push rod is used to reduce the occupied space.

[0055] Specifically, a cavity is provided inside the vertical slider 303 , one end of the cavity is connected to the power distribution and gas supply equipment 306 through a conduit, and the other end of the cavity is connected to the extension component 304 .

[0056] Through the above technical solution, a cavity is set inside the vertical slider 303, so that the conduit and the extension component 304 can be connected, so that when vacuuming, the demoulding suction cup 305 can generate suction to adsorb the product.

[0057] Specifically, the extension component 304 includes a sleeve tube 3041, a ventilated chamber is provided inside the sleeve tube 3041, and the chamber is in an inverted T shape. A rotatable limiting ring 3042 is installed inside the sleeve tube 3041, and the outer surface of the limiting ring 3042 is completely in contact with the inner wall of the sleeve tube 3041;

[0058] The bottom of the limiting ring 3042 is fixedly connected with a suspension rod 3043 . The suspension rod 3043 passes through the bottom of the sleeve tube 3041 . The demoulding suction cup 305 is installed at the bottom of the suspension rod 3043 .

[0059] Through the above technical solution, the sleeve 3041 is used to connect the vertical slider 303 and the suspension rod 3043, and a limiting ring 3042 is set at the top of the suspension rod 3043 to limit the suspension rod 3043 inside the sleeve 3041. When the suspension rod 3043 is driven by the transmission disk 402, the suspension rod 3043 can rotate to achieve the purpose of driving the product to rotate.

[0060] When in use, the vertical guide rail 302 is provided to drive the vertical slider 303 to rise and fall vertically, so that after the injection molding is completed, the demoulding suction cup 305 is driven to descend to absorb the product, and the demoulding is achieved by the rise of the demoulding suction cup 305. During the demoulding process, the transmission plate 402 drives the extension component 304 to rotate, so that the demoulding is smoother, and only one visual inspection device 5 is needed to inspect the product in an all-round manner, thereby achieving the effect of reducing the number of visual inspection devices 5 arranged;

[0061] By fixing the horizontal guide rail 301 on the inner top of the support mechanism 1, the horizontal guide rail 301 drives the vertical guide rail 302 to move horizontally. When the visual inspection device 5 completes the inspection, the electric push rod in the horizontal guide rail 301 drives the product to move forward or backward according to the inspection result, and places qualified products and unqualified products in different directions, thereby achieving the effect of product classification.
