Description

Technical Field

[0001] This utility model relates to the field of telescope accessory processing technology, specifically a multi-cavity injection mold for a telescope plastic body. Background Technology

[0002] For example, a multi-cavity injection mold for telescope accessories, as disclosed in patent publication number CN222004319U, includes a base with vibration mechanisms fixedly connected to the four corners of the top of the base. Through the cooperation of a first motor, a second threaded rod, a first support rod, a second support rod, and a top block, it has the advantage of ejection function. The user can move the position of the first movable plate using the first motor and the second threaded rod. During the movement of the first movable plate, the first and second support rods will move upwards, and the second support rod will move the top block upwards, enabling the accessory to be ejected after molding. This avoids the inability to remove the accessory from the mold when the user needs to collect it, thus saving the user a significant amount of time and effort, thereby improving molding efficiency.

[0003] However, during the use of the above-mentioned equipment, due to the setting of its internal vibration mechanism, the use of telescopes with different focal lengths and apertures requires frequent mold switching. When replacement is needed, the entire mold needs to be disassembled, which is inconvenient to start installation and disassembly, seriously affecting production efficiency. Therefore, in order to address this situation, we propose a more convenient and practical multi-cavity injection mold to meet the usage requirements. Utility Model Content

[0004] The purpose of this invention is to provide a multi-cavity injection mold for the plastic body of a telescope, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-cavity injection mold for a telescope plastic lens body, including a base, a disassembly mechanism provided at the top center of the base, the disassembly mechanism including a fixing ring, a fixing plate fixedly connected to one side of the fixing ring, a limit hole through the bottom side of the fixing plate, insertion slots provided on both sides of the top of the fixing plate, an L-shaped support plate fixedly connected to one side of the top of the base, and insertion blocks fixedly connected to both sides of the support plate, the insertion blocks and the insertion slots being compatible with each other.

[0006] Furthermore, the top of the fixing plate has multiple equally spaced slots, and a lower mold is fixedly connected inside the slots. Circular connecting plates are fixedly connected to the outer walls of both ends of the lower mold, and a mold core is provided on the inner wall of the lower mold.

[0007] Furthermore, a vibration motor is installed on the inner wall of the top of the connecting plate, and a first cylinder is installed on the inner wall of the bottom of the connecting plate.

[0008] Furthermore, a lifting plate is fixedly connected to the output end of the first cylinder, and multiple equidistant extrusion blocks are fixedly connected to the top of the lifting plate, with the extrusion blocks being adapted to the lower mold.

[0009] Furthermore, a limiting bolt is installed on one side of the bottom of the plug block, and the limiting bolt and the limiting hole are compatible. A second cylinder is installed on the inner wall of the top of the support plate, and a movable plate is fixedly connected to the output end of the second cylinder.

[0010] Furthermore, the top of the movable plate has multiple equidistant through holes, and a sliding column is slidably connected inside the through holes. One end of the sliding column is fixedly connected to an upper mold, and a spring is installed on the outer wall of the sliding column.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This telescope's multi-cavity injection mold for the plastic lens body, through its disassembly mechanism, allows for rapid assembly of the support plate and base. First, the insert blocks on both sides of the support plate are aligned with the insert slots on the top of the fixing plate, then horizontally pushed into the limiting holes. The limiting bolts are then inserted to secure the mold. The lower mold is then injected into the upper mold, which closes with the lower mold, allowing molten plastic to be injected into the mold core to form the lens body. Simultaneously, a vibrating motor vibrates synchronously to promote uniform filling of the molten plastic. During demolding, the first cylinder drives the lifting plate and extrusion block to extrude the mold. This device requires no complex tools or cumbersome steps, facilitating installation and disassembly, improving work efficiency, and demonstrating strong practicality, making it suitable for widespread adoption.

[0018] 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.

[0019] In the manufacturing process of telescopes, injection molds are required. The injection mold provided by this utility model is specifically used for the injection molding of plastic lens bodies in telescope manufacturing. When using this equipment for injection molding, the mold should be preheated before the injection operation begins to ensure that the plastic material can fill the mold cavity evenly and quickly, thereby improving injection efficiency and product quality. During the injection process, the injection pressure and injection speed should be strictly controlled to avoid the mold being subjected to excessive pressure and damaged. At the same time, it should be ensured that the plastic lens body can be fully formed and the surface is smooth and without defects. After the injection is completed, the mold should be allowed to cool down completely before disassembly to prevent the plastic lens body from deforming or being damaged due to excessive mold temperature.

[0020] like Figures 1-3 As shown, this utility model provides a technical solution: a multi-cavity injection mold for a telescope plastic lens body, including a base 1, a disassembly mechanism 2 is provided at the center of the top of the base 1, the disassembly mechanism 2 includes a fixing ring 201, a fixing plate 202 is fixedly connected to one side of the fixing ring 201, a limit hole 203 is provided through one side of the bottom of the fixing plate 202, and insertion grooves 204 are provided on both sides of the top of the fixing plate 202. An L-shaped support plate 3 is fixedly connected to one side of the top of the base 1, and insertion blocks 4 are fixedly connected to both sides of the support plate 3. The insertion blocks 4 and the insertion grooves 204 are compatible with each other.

[0021] like Figure 2 As shown, a limiting bolt 5 is installed on one side of the bottom of the plug block 4. The limiting bolt 5 and the limiting hole 203 are compatible. A second cylinder 6 is installed on the inner wall of the top of the support plate 3. A movable plate 7 is fixedly connected to the output end of the second cylinder 6. Multiple equidistant through holes are opened on the top of the movable plate 7. A sliding column 8 is slidably connected in the through holes. An upper mold 9 is fixedly connected to one end of the sliding column 8. A spring 10 is installed on the outer wall of the sliding column 8.

[0022] It should be noted that during use, the upper mold 9 is connected to the movable plate 7 via the sliding column 8 during injection molding. The first cylinder 209 drives the movable plate 7 to press down, causing the upper mold 9 to close with the lower mold 206. When opening the mold, the first cylinder 209 pulls the movable plate 7 up, disengaging the upper mold 9 from the lower mold 206. At the same time, the spring 10 buffers the impact when the upper mold 9 returns to its original position, thus preventing damage to the mold or product from rigid impacts.

[0023] like Figure 3As shown, the top of the fixed plate 202 has multiple equally spaced slots, and a lower mold 206 is fixedly connected inside the slots. Circular connecting plates 205 are fixedly connected to the outer walls of both ends of the lower mold 206. A mold core 207 is provided on the inner wall of the lower mold 206. A vibration motor 208 is installed on the top inner wall of the connecting plate 205. A first cylinder 209 is installed on the bottom inner wall of the connecting plate 205. A lifting plate 210 is fixedly connected to the output end of the first cylinder 209. Multiple equally spaced extrusion blocks 211 are fixedly connected to the top of the lifting plate 210. The extrusion blocks 211 are compatible with the lower mold 206.

[0024] It should be noted that during use, firstly, align the plug-in blocks 4 on both sides of the support plate 3 with the plug-in slots 204 on the top of the fixing plate 202, push them horizontally into the position of the limiting hole 203, insert the limiting bolts 5 to fix them, and complete the quick assembly of the support plate 3 and the base 1. When the lower mold 206 is injected into the upper mold 9 and the lower mold 206 are closed, the plastic melt is injected into the mold core 207 to form the mirror body. At the same time, the vibration motor 208 vibrates synchronously to promote uniform filling of the melt. When demolding, the first cylinder 209 drives the lifting plate 210 and the extrusion block 211 to move and extrude the mold. The disassembly mechanism 2 allows for flexible adjustment of the number of lower molds 206 or replacement of lower molds 206 of different specifications according to production needs, adapting to the production mode of multiple varieties and small batches.

[0025] During use, the plug-in blocks 4 on both sides of the support plate 3 are aligned with the plug-in slots 204 on the top of the fixing plate 202, and pushed horizontally into the position of the limiting hole 203. The limiting bolts 5 are then inserted to fix the plate, completing the quick assembly of the support plate 3 and the base 1. During injection molding, the upper mold 9 is connected to the movable plate 7 through the sliding column 8. The first cylinder 209 drives the movable plate 7 to press down, causing the upper mold 9 and the lower mold 206 to close. The plastic melt is injected into the mold core 207 to form the mirror body. At the same time, the vibration motor 208 vibrates synchronously to promote uniform filling of the melt. When the mold is opened, the first cylinder 209 pulls up the movable plate 7, and the upper mold 9 is separated from the lower mold 206. At the same time, the first cylinder 209 drives the lifting plate 210 to push out the extrusion block 211. During this process, the spring 10 can buffer the impact when the upper mold 9 is reset. This device does not require complicated tools or cumbersome steps, making it easy to start installation and disassembly, and improving work efficiency.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
