[0033] Reference Figure 2-Figure 3 , the right side of the top column 4 is fixedly connected with a top plate 5, the outside of the top plate 5 is slidably connected to the inner wall of the fixed mold 1, the four right corners of the fixed mold 1 are fixedly connected with limit columns 6, the limit columns 6 here are used to ensure the stability of this device, the outside of the limit columns 6 is slidably connected to the inner wall of the movable mold 2, the inner walls of the front and rear sides of the movable mold 2 are slidably connected to the limit frame 11, the outer side of the limit frame 11 is fixedly connected with the frame 7, and the limit frame 11 here can drive the frame 7 to move together when moving;

[0034] Reference Figure 2-Figure 3 The left inner wall of the frame 7 is in contact with the outer side of the fixed mold 1, and the right side of the movable mold 2 is fixedly connected with a back block 8, where the fixed mold 1 supports the frame 7, and the left front and rear ends of the back block 8 are fixedly connected with a cylinder 9, and the driving end of the cylinder 9 is fixedly connected with a slope block 10, where the cylinder 9 can drive the slope block 10 to move to the left, and the inner side wall of the slope block 10 is slidably connected to the outer side of the movable mold 2, and the front and rear sides of the movable mold 2 are fixedly connected with sliders 12;

[0035] Reference Figure 2-Figure 3 , the frame 7 and the slider 12 are in an engaging relationship. The slope block 10 here can squeeze the frame 7 so that it is higher than the horizontal line of the slider 12, thereby moving the movable mold 2, so that the slider 12 moves to the engaging range of the frame 7. At this time, the control cylinder 9 is recovered to complete the engagement of the slider 12 and the frame 7, so as to achieve the effect of fixing and preventing loosening. Springs 13 are provided on the front and rear sides of the movable mold 2, one end of the spring 13 is fixedly connected to one side of the inner wall of the movable mold 2, and the other end of the spring 13 is fixedly connected to one side of the limit frame 11.

[0036] Reference Figure 3-Figure 4 The inner wall of the movable mold 2 is slidably connected with an extrusion assembly, and the extrusion assembly here is used to extrude the unformed product during injection molding, thereby ensuring the sealing of the device, preventing bubbles from appearing inside it, and improving the quality of the product. The extrusion assembly includes a plate 14, and the outer portion of the plate 14 is slidably connected to the inner wall of the movable mold 2. A plurality of disks 15 are fixedly connected to the right side of the inner wall of the movable mold 2, and the left side of the disk 15 is rotatably connected to two brackets 16.

[0037] Reference Figure 2-Figure 4The left side of the bracket 16 is rotatably connected to the right side of the plate 14. The plate 14 here provides a stable support for the bracket 16. The right side of the bracket 16 is movably connected with a ball 17. The inner wall of the movable mold 2 is provided with a plurality of springs 18. One end of the spring 18 is fixedly connected to the outside of the ball 17, and the other end of the spring 18 is fixedly connected to one side of the inner wall of the movable mold 2. The ball 17 and the movable mold 2 here provide a stable expansion and contraction space for the spring 18, and provide a fixed support for it, so that the plate 14 squeezes the disk 3 tighter.

[0038] Working principle: First, the movable mold 2 can be manipulated to move to the right side of the fixed mold 1 along the limit of the limit column 6, and then the two cylinders 9 on the left side of the back block 8 are started. At this time, the cylinder 9 will drive the slope block 10 to move, so that the slope block 10 squeezes the frame 7, and drives the limit frame 11 to slide outward until the slope block 10 is inserted into the interior of the slider 12 to lift the frame 7, so that it is ready to engage with the slider 12. At this time, the movable mold 2 can continue to be controlled to move to the left, so that the fixed mold 1 and the movable mold 2 are tightly fitted. At this time, the slider 12 moves to the inner side of the inner wall of the frame 7, and by retracting the cylinder 9, the elastic force of the spring 13 decreases and the frame 7 is pulled back to its original position, so that the slider 12 and the frame 7 are completely engaged, thereby ensuring the stability of the fixed mold 1 and the movable mold 2, and the injection molding work can be started at this time.

[0039] When the injection molding starts, as the injection liquid flows into the space between the fixed mold 1 and the movable mold 2, the plate 14 will gradually be stressed, causing it to be squeezed to the right. At the same time, with the cooperation of the ball 17 and the spring 18, the two brackets 16 will begin to bend and provide a reaction force therefor, so that the molded disc body 3 is squeezed tighter, greatly improving the sealing of the device.

[0040] After the injection molding is completed, the cylinder 9 is controlled again and the above-mentioned mold closing operation is reversed to separate the slider 12 from the frame 7, and then the top column 4 is controlled to drive the top plate 5 to push out the injection molded product. At this time, the staff can take out the plate body 3.

[0041] 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. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
