Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of CT molds, in particular to a slider structure of an inverted buckle ring mold for a medical CT front cover. Background Art
[0002] Medical CT is computer tomography, which uses precisely collimated X-ray beams, gamma rays and ultrasound, together with extremely sensitive detectors, to perform cross-sectional scans one after another around a certain part of the human body. The front cover, as an important component of medical CT, has extremely high requirements for its quality and precision.
[0003] In the production process of the front cover, demolding is required after injection molding is completed. During the injection molding process, the plastic material is injected into the mold cavity and solidified after cooling to form the shape of the front cover. When the plastic is fully solidified, the mold needs to be opened and the molded front cover is taken out of the mold. The operation of separating the front cover from the mold is demolding.
[0004] In order to meet specific functional or assembly requirements, an undercut structure is set in the front cover to ensure that the front cover is more secure after assembly and is not easy to loosen or fall off. However, this causes the undercut structure to form a reverse engagement or hooking with the mold cavity, preventing the product from being directly ejected along the normal demolding direction. The traditional demolding mechanism uses simple linear motion, which is difficult to cope with the complex undercut structure, resulting in slow demolding speed and inaccurate demolding. Therefore, a medical CT front cover undercut ring mold slider structure is proposed to solve the above problems. Utility Model Content

The sides away from the plurality of T-shaped sliders 6 are fixedly connected to the slider inserts 7, and the bottoms of the plurality of slider inserts 7 are slidably connected to the guide rails 8, and the outer walls of the plurality of slider inserts 7 are fixedly connected to the linkage inserts 10, and the bottoms of the plurality of linkage inserts 10 are provided with moving mechanisms 2, and the moving mechanisms 2 are used to drive the linkage inserts 10 to slide; the adjacent sides of the plurality of linkage inserts 10 are fixedly connected to the cover plates 9, and the tops of the plurality of cover plates 9 are provided with mounting holes 12; the top of the slider seat 5 is fixedly connected to the limit plate 13, and the top of the limit plate 13 is arranged at the bottom of the shell 3;
[0034] Specifically, the cylinder 4 provides power to drive the slider seat 5 to move up and down, and the slide groove 15 opened inside the slider seat 5 supports the sliding of the T-shaped slider 6. The slider insert 7 connected to the T-shaped slider 6 can slide left and right in the bottom guide rail 8. When the cylinder 4 moves up and down, it drives the slider seat 5 to move up and down. When the T-shaped slider 6 is at the top of the slider seat 5, it and the slider insert 7 are against the product front cover 1. When the slider seat 5 moves upward, a gap is left between the T-shaped slider 6 and the slider seat 5, so that the slider insert 7 slides inward autonomously, so that the slider insert 7 drives the linkage insert 10 to detach from the product front cover 1, so as to achieve fast and accurate detachment from the double-layer inverted structure of a ring on the inner side of the product front cover 1, thereby reducing the demolding time and improving the production efficiency.
[0035] See attached Figure 1 , Attachment Figure 2 and attached Figure 3The moving mechanism 2 includes a plurality of guide seats 201, the outer walls of the plurality of guide seats 201 are fixedly connected to the inner side of the bottom of the linkage insert 10, the inner sides of the plurality of guide seats 201 are provided with a plurality of annular grooves 205, the middle parts of the plurality of linkage inserts 10 are fixedly connected with a fixed block 202, the bottoms of the plurality of fixed blocks 202 are fixedly connected with a plurality of guide pillars 204, the outer walls of the plurality of guide pillars 204 are slidably connected to the inner side of the annular groove 205, the far side of the plurality of fixed blocks 202 are fixedly connected with a limiting block 203, and the bottoms of the plurality of limiting blocks 203 are arranged on the top of the guide seat 201;
[0036] Specifically, through the fixed connection between the linkage insert 10 and the fixed block 202, when demolding, the linkage insert 10 moves inward, driving the guide column 204 set at the bottom of the fixed block 202 to move, and the accuracy and safety of the movement of the linkage insert 10 are guaranteed by the guide seat 201 and the limit block 203. At the same time, the annular groove 205 is provided to support the movement of the guide column 204, avoiding equipment damage caused by excessive movement. This design can effectively reduce the shaking and deviation of the linkage insert 10 during the movement, making the entire demolding process more stable, and reducing the risk of mold damage or product defects caused by unstable movement.
[0037] See attached Figure 1 , Attachment Figure 2 and attached Figure 3 , a plurality of linkage inserts 10 are provided with a moving groove 11 on the adjacent side, and a plurality of cover plates 9 are slidably connected to the inner side of the moving groove 11 on the far side; a plurality of slider inserts 7 are provided with a moving groove 2 17 on the top, and a plurality of connecting pieces 16 are slidably connected to the inner side of the moving groove 2 17; a plurality of cover plates 9 and connecting pieces 16 are provided with a mounting hole 12 on the top, and the top of the cover plate 9 is threadedly connected to the housing 3; a mounting hole 2 14 is provided at the four corners of the top of the limiting plate 13, and the inner side of the mounting hole 2 14 is threadedly connected to the bottom of the housing 3;
[0038] Specifically, when the linkage insert 10 moves, the cover plate 9 slides in the moving groove 11, and when the slider insert 7 moves, the connecting member 16 slides in the moving groove 2 17. The cover plate 9 and the connecting member 16 are both connected to the top shell 3 through the mounting hole 12. At the same time, the mounting hole 2 14 is set on the limit plate 13, which can connect the shell 3 and the limit plate 13 to ensure the integrity of the structure.
[0039] Working principle: a slider structure is arranged on the inner side of the product front cover 1. In the initial state, the T-shaped slider 6 is at the top of the slider seat 5 and fixed in the slide groove 15 inside the slider seat 5. When the product front cover 1 needs to be demoulded, the cylinder 4 is started to lift the slider seat 5, and the slider seat 5 moves upward, and the T-shaped slider 6 slides in the slide groove 15. At this time, the inclined surface on the top of the T-shaped slider 6 is separated from the inclined surface on the top of the slider seat 5, so that the T-shaped slider 6 loses its support, and a gap is left between the T-shaped slider 6 and the slider seat 5, so that the slider insert 7 slides inward on the guide rail 8 autonomously, and pushes the T-shaped slider 6 inward to resist the slider seat 5. The four slider inserts 7 slide inward, driving the four linkage inserts 10 engaged with the outer wall of the slider insert 7 to move inward, thereby disengaging from the double-layer inverted structure of a ring on the inner side of the product front cover 1.
[0040] When the linkage insert 10 moves inward under the force, the fixed block 202 fixed on the inner side of the linkage insert 10 also moves accordingly. The bottom of the fixed block 202 is connected to the inclined guide column 204 which slides in the annular groove 205 on the inner side of the guide seat 201. Finally, the limit block 203 limits the sliding range of the guide column 204 to prevent excessive movement of the linkage insert 10.
[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.
