Description

Technical Field

[0001] The utility model relates to the technical field of sliders, in particular to a slider mechanism for a mold. Background Art

[0002] The slider mechanism is an important part of stamping machinery, mainly used for stamping and forming of metal materials. It is usually composed of an upper die and a lower die. The slider is the main stamping component, which forms the material during its movement. The working principle of the slider mechanism is that the slider reciprocates between the upper die and the lower die, so that the material gradually deforms and forms the desired product shape under the action of the die pressure. The synchronous drive of the upper die and the lower die can ensure that the die always maintains an accurate relative position during the closing and opening process, which is conducive to improving the forming accuracy of the product.

[0003] After searching, a slider mechanism is disclosed in the announcement number: CN202123621U, which is applied to a mold for producing products with a large-area barb on one side wall. The mold includes a female template, a male template, a female mold core and a male mold core, and is characterized in that the slider mechanism includes: a lower middle plate, which is arranged on the male template; an upper middle plate, which is arranged between the lower middle plate and the female template; a first slider, which is movably arranged on the upper middle plate; a second slider, which is movably arranged on the lower middle plate; a first positioning pull plate, which connects the female template and the upper middle plate when the mold is opened; a second positioning pull plate, which connects the upper middle plate and the lower middle plate when the mold is opened; a mold locker, which connects and locks the female template, the upper middle plate and the male template when the mold is closed; an opener and closer, which is arranged between the lower middle plate and the male template. The slider mechanism of the utility model has a simple structure, low manufacturing cost and high stability. In this application, a one-mold-multiple-cavity design can be made, avoiding the low production efficiency during the horizontal mold design. At the same time, it has a simple structure, low manufacturing cost and high stability. Such a setting makes it difficult to achieve synchronous drive movement of the upper mold and the lower mold, resulting in uneven stress on the mold when opening the mold, increasing the risk of mold damage.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0030] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: a slider mechanism for a mold, comprising an upper template 1, a lower template 2 is arranged below the upper template 1, a limiting assembly is arranged on the outer wall of the lower template 2, an ejector plate 4 is arranged below the lower template 2, a support rod 5 is fixedly connected to the upper surface of the ejector plate 4, one end of the support rod 5 is fixedly connected to a bearing 6, a gear 7 is fixedly connected to the outer wall of the bearing 6, a rack 8 is arranged inside the upper template 1, the rack 8 is meshed with the gear 7, the outer wall of the rack 8 is arranged inside the lower template 2, a telescopic rod 9 is fixedly connected to the lower surface of the lower template 2, a spring 10 is sleeved on the outer wall of the telescopic rod 9, one end of the spring 10 is fixedly connected to the lower surface of the lower template 2, and the other end of the spring 10 is fixedly connected to the upper surface of the ejector plate 4, the limiting assembly comprises a limiting plate 3, the outer wall of the limiting plate 3 is slidably connected to the outer wall of the lower template 2, and the lower surface of the limiting plate 3 is fixedly connected to the upper surface of the ejector plate 4;

[0031] Specifically, the upper template 1 is first driven to move, which not only drives the rack 8 to slide inside the lower template 2, but also due to the meshing relationship between the gear 7 and the rack 8, the gear 7 will rotate with the movement of the rack 8. In order to ensure the smooth rotation of the gear 7, a bearing 6 is designed to enable the gear 7 to rotate smoothly at one end of the support rod 5. As the gear 7 rotates, the rack 8 on the other side of the meshing will move in the opposite direction. The reverse movement causes the lower template 2 to gradually move downward, and at the same time, pressure is applied to the spring 10 to shrink it, thereby realizing the synchronous movement of the upper template 1 and the lower template 2. When the product needs to be removed from the mold, only the drive to the upper template 1 needs to be released. At this time, the previously compressed spring 10 is no longer subjected to force, so it will rebound and push the lower template 2 back to its original position. Through this design, the automatic mold closing function of the upper template 1 and the lower template 2 is realized, which greatly improves the production efficiency and the convenience of operation.

[0032] Reference Figure 1 - Figure 3 The upper template 1 is fixedly connected with an inclined guide column 11, the outer wall of the inclined guide column 11 is fixedly connected with a module 12, the outer wall of the module 12 is arranged inside the upper template 1, the bottom of the module 12 is fixedly connected with a slider 13, the outer wall of the slider 13 is slidably connected to the inside of the lower template 2, a top head 14 is arranged inside the module 12, a slide groove 19 is opened inside the ejector plate 4, the outer wall of the top head 14 is rotatably connected with an inclined ejector rod 15, one end of the inclined ejector rod 15 is rotatably connected with an inclined ejector seat 17, the lower template 2 is fixedly connected with a limiting block 16, the limiting block 16 is slidably connected to the outer wall of the inclined ejector rod 15, the bottom of the inclined ejector seat 17 is provided with a sliding block 18, the outer wall of the sliding block 18 is slidably connected to the inside of the ejector plate 4, and a guide column 20 is arranged at the bottom of the top head 14;

[0033] Specifically, the upper template 1 and the lower template 2 move respectively. First, the upper template 1 drives the inclined guide column 11 to move outward. The inclined guide column 11 is connected to the module 12. Therefore, as the inclined guide column 11 moves, the module 12 will move outward accordingly. At the same time, the movement of the lower template 2 will drive the limit block 16 to move. The limit block 16 cooperates with the inclined ejector rods 15 on both sides. When the limit block 16 moves, it will drive the two inclined ejector rods 15 to move in the opposite direction, ensuring that the product inside the mold can be accurately ejected. During the entire movement process, the inclined ejector seat 17 and the sliding block 18 play a key role. The inclined ejector seat 17 and the sliding block 18 cooperate with each other and slide inside the slide groove 19, which not only ensures the stable guidance of the bottom of the inclined ejector rod 15, but also ensures the smooth progress of the entire ejection process. Finally, the top of the inclined ejector rod 15 drives the ejector head 14 to move, and the ejector head 14 is in direct contact with the product, thereby achieving the purpose of ejecting the product from the mold, which not only improves the production efficiency but also ensures the integrity and quality of the product.

[0034] Working principle: When the slider mechanism for the mold is needed, first drive the upper mold plate 1 to move, thereby driving the rack 8 to slide inside the lower mold plate 2. At the same time, due to the meshing of the gear 7 and the rack 8, the gear 7 rotates with the movement of the rack 8. At this time, the gear 7 rotates smoothly at one end of the support rod 5 through the bearing 6, and then the rack 8 on the other side moves in the opposite direction through the rotation of the gear 7, so that the lower mold plate 2 gradually moves downward, and at the same time, the spring 10 contracts, thereby realizing the synchronous movement of the upper mold plate 1 and the lower mold plate 2. When the product is taken out, release the upper mold plate 1, and the spring 10 is no longer stressed and rebounds, thereby The lower template 2 is pushed to its original position, realizing the automatic mold closing of the upper template 1 and the lower template 2. When the upper template 1 and the lower template 2 are opened, the movement of the upper template 1 drives the inclined guide column 11 to move outward, thereby driving the slider 13 to move outward through the module 12, and at the same time, the movement of the lower template 2 drives the limit block 16 to move, and then the movement of the limit block 16 drives the inclined ejector rods 15 on both sides to move in the opposite direction. In this process, the inclined ejector seat 17 cooperates with the sliding block 18 to slide inside the slide groove 19 to guide the bottom of the inclined ejector rod 15, and finally the top of the inclined ejector rod 15 drives the ejector head 14 to move, thereby ejecting the product.

[0035] 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.
