[0017] An automatic unloading mechanism in a glass guide groove mold, such as Figs. 1-2 As shown, it includes a support plate 1, a product plastic insert 2, a mold plate 3, a moving plate 4, a joint assembly 5, a drive mechanism 6, a core retraction assembly 7, a first connecting rod 8, a second connecting rod 9, a reserved empty stroke groove 10, a baffle 11, a protrusion 12, a front bending plate 13, an elongated hole 14, a screw sleeve assembly 15, a lever 16, an insert plate 17, a demolding undercut area 18, a through hole 19, a limiting plate 20, and a sliding key 21.
[0018] A mold plate 3 is provided on the support plate 1. The product plastic insert 2 is installed on the mold plate 3. A movable plate 4 is slidably installed at the middle position of the left and right sides of the bottom of the support plate 1. One end of the movable plate 4 is connected to a drive mechanism 6 through a connector assembly 5. The other end of the movable plate 4 extends out of the bottom of the support plate 1 and a core retraction assembly 7 is installed on its upper surface. A first connecting rod 8 is installed on the core retraction assembly 7. A second connecting rod 9 is slidably installed on the front side of the upper surface of the support plate 1. A reserved empty stroke groove 10 is provided on the upper surface of the end of the second connecting rod 9 that extends out of the support plate 1. A baffle 11 is provided. The bottom of the first connecting rod 8 is provided with a protrusion 12 corresponding to the reserved empty stroke groove 10. The protrusion 12 is set in the reserved empty stroke groove 10. The second connecting rod 9 is provided with a front bending plate 13 at one end above the support plate 1. An elongated hole 14 is opened on the front bending plate 13. A screw sleeve assembly 15 is inserted into the elongated hole 14. A lever 16 is fixedly connected to the bottom of the screw sleeve assembly 15. The lever 16 is slidably installed on the support plate 1. An insert plate 17 is installed at the other end of the lever 16. The insert plate 17 is inserted into the demolding undercut area 18 of the plastic insert 2 of the product.
[0019] The second connecting rod 9 has a through hole 19. A limit plate 20 is fixed to the upper surface of the support plate 1 by bolts. The limit plate 20 is set in the through hole 19, and the length of the limit plate 20 is less than the length of the through hole 19.
[0020] The end of the lever 16 is provided with a mounting groove and a slide key 21 is provided in the mounting groove. The insert plate 17 is fixed to the top of the slide key 21 by bolts.
[0021] The upper surface of the support plate 1 is provided with a groove, and the bottom of the lever 16 is provided with a mounting block, which is slidably installed in the groove.
[0022] The driving mechanism 6 is a cylinder, but is not limited to a cylinder, and any driving assembly that can achieve this function can be used.
[0023] The product plastic insert 2 is fixed on the positioning pin hole of the mold plate 3 through the positioning pin shaft, and the first connecting rod 8 is fixed on the core retreat assembly 7; the first connecting rod 8 and the second connecting rod 9 have a reserved idle stroke groove 10 and a protrusion 12 that cooperate with each other, and when moving relative to each other, the other is driven to move, and the reserved idle stroke groove 10 is arranged in the relative position relationship to meet the retreat demand of the plug-in plate 17; the screw sleeve assembly 15 is fixedly installed on the lever 16 and passes through the long circular hole 14 on the front bending plate 13; according to the demolding direction demand of the product structure, the second connecting rod 9 and the lever 16 have a certain angle in the movement direction; the other section of the lever 16 wraps the slide key 21, which can drive the slide key 21 to move; the plug-in plate 17 is fixedly installed on the slide key 21; the driving mechanism 6 is connected with the core retreat assembly 7 through other connecting rod assemblies in the mold, i.e., the moving plate 4, to drive the core retreat assembly 7 to act.
[0024] When the demolding action starts, the driving mechanism 6 starts to exert force, drives the moving plate 4, first drives the core retreat assembly 7 to retreat, and the first connecting rod 8 fixed on the core retreat assembly 7 also retreats; because there is a difference between the required demolding retreat stroke of the plug-in plate 17 and the required demolding retreat stroke of the core retreat assembly 7, the required retreat amount of the plug-in plate 17 is smaller, so an idle stroke is reserved between the first connecting rod 8 and the second connecting rod 9. When the first connecting rod 8 retreats a certain distance and starts to contact the second connecting rod 9, the second connecting rod 9 retreats, and the long circular hole 14 on the second connecting rod 9 drives the screw sleeve assembly 15, because the screw sleeve assembly 15 is fixed on the lever 16, the lever 16 retreats; the lever 16 retreats to drive the slide key 21 to retreat, and at the same time, the plug-in plate 17 retreats. The retreat of the plug-in plate 17 releases the demolding reverse buckling area 18, meets the demolding demand of the final product, can exert force upward to make the product plastic insert 2 positioning pin hole part separate from the mold plate 3, and completes the demolding.
[0025] When preparing for the next molding, the mold is in an open state, first, the product plastic insert 2 is fixed on the mold plate 3 through the positioning pin shaft, and then the driving mechanism 6 is reversely moved, the first connecting rod 8 on the core retreat assembly 7 drives the second connecting rod 9 and the lever 16, and drives the plug-in plate 17 to return to the original position, the whole action process is opposite to the demolding action, and the cycle is repeated.
[0026] The utility model solves the problem that the end of the guide groove product has plastic inserts and glue reduction reverse buckling cannot demould, guarantees that the product is beautiful and has no deformation after demoulding, improves product pass rate, reduces product mould time, reduces the labor intensity and manual cost of workers, is stable in movement, is convenient for feeding operation after demoulding is completed and is returned to the original position, improves production efficiency, and satisfies various requirements of large-scale production.
[0027] The utility model is described above in connection with the drawings, and obviously, the specific implementation of the utility model is not limited by the above mode, and various improvements adopting the method concept and technical scheme of the utility model or direct application in other occasions without improvement are all within the protection scope of the utility model.
