Description

Technical Field

[0001] This utility model relates to the field of mold core removal, specifically a device for removing the lower mold core of a multi-cavity mold. Background Technology

[0002] In the molding process of optical glass aspherical lenses, multi-cavity molds are widely used. The diameter of optical glass aspherical molds is mostly between 5-65 mm. In the industry, mold cores with a diameter of 5-17 mm commonly use three, six, or nine cavities to improve production efficiency. These molds are usually composed of an upper mold core and a lower mold core. The lower mold cores are embedded in a common mold core fixing plate (or cavity plate) in an array. The mold is usually composed of upper and lower mold cores. When using it, if one cavity needs to be removed, one hand needs to hold the other cavities in place while the other hand removes it. However, when there are many cavities in the mold, the mold core size is small, and the number of cavities is large, it is not very convenient to remove it.

[0003] Therefore, a device for removing the lower mold core of a multi-cavity mold is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a device for removing the lower mold core of a multi-cavity mold.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The multi-cavity mold lower mold core removal device of this utility model includes a mold removal shell; the bottom of the mold removal shell has a first opening, and the side of the first opening has a second opening; a cylinder is fixedly connected to the surface of the mold removal shell, and a limiting piece is fixedly connected to the output end of the cylinder; a groove is provided on the inner side of the mold removal shell; this step, by setting the first opening and the second opening, allows the position of the lower mold to be observed through the first opening, and the cylinder pushes the limiting piece to fit against the surface of the cavity to position the angle of the mold removal shell, so as to align the second opening with the lower mold to be removed, and then the lower mold can be removed, avoiding damage caused by the lower mold falling in batches under its own weight.

[0006] Preferably, a groove is provided on the side of the second opening, and a limiting plate is slidably connected to the inner side of the second opening. The limiting plate is slidably connected to the second opening. This step allows the limiting plate to slide inside the second opening, which can limit the lower mold and prevent the lower mold from falling through the second opening before the second opening is rotated to the point where the lower mold is to be removed.

[0007] Preferably, an annular groove is provided on the inner side of the mold-taking shell, and a ball bearing is rolledly connected to both the annular groove and the top of the limiting plate. This step, by setting the annular groove and several ball bearings, allows the ball bearings to support the bottom surface of the lower mold while rolling, thus supporting the bottom of the lower mold and reducing wear on the bottom surface of the lower mold when the mold-taking shell rotates.

[0008] Preferably, the surface of the mold-taking shell is bolted with an identification mark, and the identification mark is slidably connected to the mold-taking shell; this step, by setting several identification marks, allows the identification marks to be disassembled and replaced, and different acupoints can be distinguished by color or marked with numbers, thus avoiding operational errors.

[0009] Preferably, a spring is fixedly connected inside the slide groove, one end of the spring is fixedly connected to the limiting plate, and a handle is fixedly connected to the bottom of the limiting plate; this step allows the limiting plate to be pulled and moved by the handle, and the limiting plate can be pushed to reset by the spring, increasing the stability of the limiting plate when supporting the bottom of the lower mold.

[0010] Preferably, the bottom of the mold-taking shell is provided with an observation window, and several observation windows are provided; this step, by providing several observation windows, makes it easier for the staff to observe the remaining quantity of the lower mold inside the mold-taking shell.

[0011] The advantages of this utility model are: 1. The multi-cavity mold lower mold core removal device of this utility model is provided with a first opening and a second opening. The position of the lower mold can be observed through the first opening. The cylinder pushes the limiting plate to fit with the surface of the cavity to position the angle of the mold removal shell so that the second opening is aligned with the lower mold to be removed. Then the lower mold can be removed, avoiding damage caused by the lower mold falling in batches under its own weight.

[0012] 2. The multi-cavity mold lower mold core removal device of this utility model, by setting an annular groove and several balls, allows the balls to support the bottom surface of the lower mold while rolling, which can support the bottom of the lower mold and reduce the wear of the lower mold bottom surface when the mold removal shell rotates.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 4 As shown, a multi-cavity mold lower core removal device includes a mold removal shell 1; the bottom of the mold removal shell 1 has a first opening 12, and the side of the first opening 12 has a second opening 13; a cylinder 14 is fixedly connected to the surface of the mold removal shell 1, and a limiting piece 15 is fixedly connected to the output end of the cylinder 14; a groove 16 is provided on the inner side of the mold removal shell 1; during operation, when it is necessary to remove one of the cavities, the mold removal shell 1 is inserted into the bottom of the cavity, and then the corresponding second opening 13 is rotated to the cavity to be removed. At this time, the cylinder 14 pushes the limiting piece 15 out of the groove 16, so that the groove 16 abuts against the surface of the cavity. Position the mold removal shell 1, and then the lower mold can be removed. When it is necessary to continue rotating the mold removal shell 1, the cylinder 14 drives the limiting piece 15 to separate from the cavity surface and enter the groove 16, so that the second opening 13 is misaligned with the lower mold. This step is achieved by setting the first opening 12 and the second opening 13. The position of the lower mold can be observed through the first opening 12. The cylinder 14 pushes the limiting piece 15 to fit against the surface of the cavity to position the angle of the mold removal shell 1, so that the second opening 13 is aligned with the lower mold to be removed. Then the lower mold can be removed, avoiding damage caused by the lower mold falling in batches under its own weight.

[0018] like Figure 1 and Figure 5As shown, a sliding groove 21 is provided on the side of the second opening 13, and a limiting plate 22 is slidably connected to the inner side of the second opening 13. The limiting plate 22 is slidably connected to the second opening 13. During operation, when the mold housing 1 rotates, it drives the limiting plate 22 to move. The limiting plate 22 supports the bottom of the lower mold. When the lower mold needs to be removed, the limiting plate 22 is pulled outward to separate the limiting plate 22 from the bottom of the lower mold. Then the lower mold can be removed. This step is achieved by the limiting plate 22 sliding inside the second opening 13, which limits the lower mold and prevents the lower mold from falling through the second opening 13 before the second opening 13 is rotated to the point where the lower mold is to be removed.

[0019] like Figure 2 and Figure 4 As shown, an annular groove 31 is provided on the inner side of the mold-taking shell 1. Both the annular groove 31 and the top of the limiting plate 22 are rolled with balls 32. During operation, when the mold-taking shell 1 rotates, it drives the annular groove 31 to rotate. The balls 32 support the bottom of the lower mold. When the mold-taking shell 1 rotates, the balls 32 roll. When the limiting plate 22 moves, the balls 32 on the top of the limiting plate 22 roll at the bottom of the lower mold. This step, by setting the annular groove 31 and several balls 32, allows the balls 32 to support the bottom surface of the lower mold while rolling, thus supporting the bottom of the lower mold and reducing wear on the bottom surface of the lower mold when the mold-taking shell 1 rotates.

[0020] like Figure 1 and Figure 3 As shown, the surface of the mold-taking shell 1 is connected to an identification mark 41 by bolts, and the identification mark 41 is slidably connected to the mold-taking shell 1. This step, by setting several identification marks 41, allows the identification marks 41 to be disassembled and replaced, and different acupoints can be distinguished by color or marked with numbers to avoid operational errors.

[0021] like Figure 1 and Figure 5 As shown, a spring 51 is fixedly connected inside the slide 21. One end of the spring 51 is fixedly connected to the limiting plate 22, and a handle is fixedly connected to the bottom of the limiting plate 22. This step allows the limiting plate 22 to be moved by pulling it with the handle, and the limiting plate 22 can be pushed back to its original position by the spring 51, thereby increasing the stability of the limiting plate 22 when supporting the bottom of the lower mold.

[0022] like Figure 1 and Figure 3 As shown, an observation window 61 is provided at the bottom of the mold-taking shell 1, and several observation windows 61 are provided; by setting several observation windows 61, this step makes it easier for the staff to observe the remaining quantity of the lower mold inside the mold-taking shell 1.

[0023] The working principle is as follows: When it is necessary to remove one of the cavities, the mold-removing shell 1 is embedded into the bottom of the cavity. Then, the corresponding second opening 13 is rotated to the cavity to be removed. At this time, the cylinder 14 pushes the limiting piece 15 out of the groove 16, so that the groove 16 abuts against the surface of the cavity, positioning the mold-removing shell 1. Then the lower mold can be removed. When it is necessary to continue rotating the mold-removing shell 1, the cylinder 14 drives the limiting piece 15 to separate from the surface of the cavity and enter the groove 16, so that the second opening 13 is misaligned with the lower mold. When the mold-removing housing 1 rotates, it drives the limiting plate 22 to move. The limiting plate 22 supports the bottom of the lower mold. When the lower mold needs to be removed, the limiting plate 22 is pulled outward to separate the limiting plate 22 from the bottom of the lower mold. Then the lower mold can be removed. When the mold-removing housing 1 rotates, it drives the annular groove 31 to rotate. The lower mold bottom is supported by the ball bearings 32. When the mold-removing housing 1 rotates, the ball bearings 32 roll. When the limiting plate 22 moves, the ball bearings 32 at the top of the limiting plate 22 roll at the bottom of the lower mold.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
